Innovations

Kalzip XT – for a new architectural eraKalzip XT profiles enable for the first time the implementation of computer-generated forms and design principles. Evolutionary animations, visualised in 3D objects, give birth to new architectural-organic forms – the fusion of biology and architecture.

The advantages in summary:• Horizontal and vertical profiled sheets in

convex and concave forms are possible• New variations in the design of

geo me tries thanks to XT free-form profiled sheets

• Small bending radii guarantee the roofing of unusual building forms

Further information can be found on page 7 and page 28.

The integrated Kalzip renovation concept – the durable roof renovationEmergency repairs to the roofs of old existing buildings are connected with risks, since expensive consequential damage can still occur despite that and the costs can rise dramatically when ‘permanent building sites’ are the result. The Kalzip renovation concept for old roofs takes a new, sustainable path: the sloping roof with a roof cladding made of aluminium profiled sheets and adaptation to the latest thermal insulation standards.

The advantages of the Kalzip renovation concept: • Maximum corrosion resistance due to salt

water-resistant aluminium base material• Permanent, virtually maintenance-free

building protection• High creative freedom due to individual

roof forms• No interruption of use during renovation• Economical, fast installation

The thermal bridge-optimised composite clip for Kalzip profiled sheets for the achievement of EnEV 2009-compliant roof structuresThe Kalzip composite clip consists of a stable steel core, which is encased by a glass-fibre reinforced plastic.

Advantages of the product:• Minimum heat transfer enables a roof

structure that is virtually free of thermal bridges

• Safe load dissipation into the substructure

• In order to achieve the desired thermal insulation thicknesses in EnEV 2009-compliant Kalzip roof structures and to compensate for height tolerances, the new Kalzip composite clips can be combined with spacer pads

The system and its components

3.2 Aluminium clip and thermal barrier pads

Aluminium clip rods can be used for clip rods, eaves, gutter brackets and fixed points. The clips must be fixed to a steel, aluminium or timber substructure. The clips are attached to the substructure with the building authority-approved connecting

elements. To connect the profiled sheets to concrete substructures, spacer struc-tures made of steel, aluminium or timber and anchored sufficiently in the concrete must be placed in-between. Thermal barrier pad (TK 5 or 15 mm thick)

Kalzip composite clipThe energy-saving clip for attaching Kalzip profiled sheets. According to the European energy-saving directives, which are an inte-gral part of building regulations in several countries, it is now obligatory to take account of thermal bridges when planning building projects.

The Kalzip composite clip, which is used to attach the Kalzip aluminium profiled sheets to the substructure of the roof, fulfills this

requirement in an exemplary manner. It pre vents thermal bridges and succeeds in creating a system which is virtually cold-bridge free, therefore optimizing the per-formance and efficiency of the roof. This creates a roof design with heat transfer coefficients which are entirely determined by the thermal insulation. All characteristics and functions relating to the load carrying capacity and attachment are fulfilled and are documented in the approval granted by the German General Bulding Inspecto-

rate approval. The clip has a PA structure which is reinforced with steel. E spacer caps can be connected in between for varying the required thickness of thermal insu lation.

In principle, the Kalzip composite clip type E is attached to the substructure using the same connecting elements as those used with the aluminium clip.

Kalzip DuoPlus rotatable clips and Kalzip DuoPlus rail, perforatedWith the development of the DuoPlus rail and the DuoPlus clip, a solution has been found which makes the installation of the attachment elements for Kalzip profiled sheets even more secure. This solution significantly increases ease of installation and further improves thermal insulation in comparison to conventional roof designs. (See diagram page 47).

After installing the insulant (d = 100 mm), the rails are aligned according to the cal-culation and mounted with the fastener systems of SFS intec SD2-S16-6.0 x L in the steel trapezoidal profile subshell.

Sub sequent ly, the DuoPlus clips are ma-nually screwed in. Although these remain adjustable, the DuoPlus rail still offers a secure hold; therefore DuoPlus 100 can

be adapted to the individual circumstan-ces depending on the profile dimension and/or tolerance. Therefore a customised and convenient installation is guaranteed every time.

Use of spacer caps in combination with the Kalzip composite clip The Kalzip composite clips can be combined with spacer caps (DK) in order to compensate for height tole-rances. A combination is thereby permissible only in following variants.

3.3 Different finishes and colours

Stucco-embossed surfaceThe standard version of Kalzip profiled sheets is stucco-embossed. The robust stucco embossed finish is created by treat-ment with additional embossing rollers. Due to the special texture of the material surface, minor dents and accidental damage is hardly visible. In addition, the surface diffuses reflected light and minimises the risk of any dazzling effect.

Kalzip AluPlusZincAluPlusZinc from Kalzip GmbH is a fusion of two of the most established materials in industry – aluminium and zinc. Manu-factured according to the most stringent quality standards, this is a technically ad-vanced product which sets new standards. It combines stunning aesthetics with the highest quality materials to achieve design perfection.

The patented PEGAL process produces a durable fusion between aluminium and zinc. An additional surface treatment creates a stable patina with exceptionally high resis-tance to the effects of weathering. Indeed, tests in accordance with DIN 50017 KFW (cyclic condensate tests) in addition to HCT tests have proven that Kalzip AluPlusZinc out performs conventional zinc surfaces in terms of resistance to corrosion. This sur-face finish creates an appearance of classic elegance, which makes it ideal for a wide range of applications.

Kalzip AluPlusZinc offers unique product advantages:• Zinc patina with surface protection• Sophisticated, traditional impression• Bright surface• Longevity due to aluminium core• UV-resistant

Kalzip AluPlusPatinaSpecial surface treatment of the pre wea-thered, stucco-embossed profiled sheets significantly reduces their natural sheen, thereby creating a new and attractive de-sign with a high-quality appearance. With charac teristics comparable to those of an aluminium profiled sheet which has been weathered over years, this elegant and matt surface pro vides roofs and facades with impressive style.

The natural ageing process, which the profile sheets undergo during exposure to weathering, is not hindered and pro ceeds in the usual manner. In addition to the new and attractive surface finish, and the highly diverse design opportunities which this creates for planners and architects, Kalzip AluPlusPatina offers all the product advan-tages of the standard, stucco-embossed design.

Advantages of the product:• Resistant to weathering and to

aggressive environmental influences• Considerably less light reflection• Matt look due to pre-weathered surface• Decreased glare due to diffuse light

reflections• Dirt-repellent surface

– insensitive to fingerprints• Available in a stucco embossed

or smooth finish• UV-resistant

Coil-CoatingLiquid lacquer is rolled onto the alumi ni um layer in a coil coating process. These colour coated coils are then used to roll-form the Kalzip profiles.

Kalzip profile boards with polyester coating The coating is robust and insensitive to scratching; it has very good forming cha-racteristics and good resistance to weat-hering and UV light. Kalzip profiled sheets in a polyester execution are mainly used in locations with normal environmental influences.

Kalzip profiled sheets with a PVDF coatingThis coating is particularly well suited for aggressive environments and extreme climatic conditions, e.g. proximity to salt water. Profiled sheets with a PVDF coating are characterised by outstanding UV-resis-tance, have very good forming characte-ristics and are primarily used for façade design.

Kalzip ProTect coatingFor the protection of the surfaces, Kalzip additionally offers a high-quality and extra-ordinarily weather-resistant special high-end coating on the basis of a polymer technology using fluorocarbon (FLP). It is characterised by extremely high resistance to scratching, maximum colour and gloss stability as well as considerably higher surface hardness and temperature resis-tance.

The system and its components

Characteristics of the ProTect coating:• Available for RAL, NCS and metallic

shades of colour• Outstanding long-term characteristics

with minimum chalking tendency• Very good dirt repulsion due to a

Teflon-like behaviour, thus less cleaning effort necessary

• Resistant to chemicals and also to aggressive emissions such as aircraft exhaust gases

• An ‘anti-graffiti effect’ is achieved by means of the FLP technology and an additional clear lacquer, offering effective protection against vandalism

• Also available with high gloss surfaces• Corresponds to the test conditions

of the Florida test (outdoor storage for over 20 years)

Colour rangeIn addition to the diverse range of shape variants, Kalzip also offers a wide range of colour and surface finishes which provides optimum design freedom and safety. Spe-cial colours are available on request.

Controlled colour qualityThe aluminium strips coated using the coil coating process pass through a large number of elaborate processing steps.Depending on the type of coating, they are subjected to different pretreatments and painted in the desired colour or sealed with a clear varnish. Aluminium strips with a single-sided coating are given a coat of protective varnish on the rear side.

In order to achieve a weather-resistant and colourfast coating, only high-quality enamels on a polyester, PVDF or CFTE basis are used. The coil coating process is monitored according to the standards of the ECCA (European Coil Coating Asso-ciation). Important criteria here are: colour, degree of gloss, paint coating thickness, paint hardness, paint adhesion and ductility.

There are additional long-term tests such as the acid salt spray test, QUV-B test, condensation climate in an atmosphere containing SO2 and outdoor weathering tests in an aggressive environment.

PlatingPlated with a special alloy, the aluminium core is additionally protected. The thick- ness of the protective layer is only 4 % of the material itself. During the rolling process, a permanent joint between the plating and the core material is achieved.

The electro-chemical potential of the pla-ting is lower than that of the core material and therefore has the effect of a sacrificial anode in case of exposure to corrosive agents. Corrosion does not attack the core material but is limited to the plating. This protection remains effective even if the surface of the sheets is damaged.

The performance of the protective plating has been proved by several tests carried out by “Bundes anstalt für Materialforschung und Prüfung (BAM) in Berlin” (German Federal Institute for material research and testing).

The advantages in summary:• Reduced surface reflection compared

to Alu-Natur• Calm metallic impression• Salt water resistant• Even surface greying• Resistant to weathering and to

aggressive environmental influences

Protective filmAt the customer‘s request and/or due to production requirements, surfaces are protected against possible damage with an appropriate film. It must be ensured that the film is removed within two weeks of delivery in order to prevent increased effort for its removal.

Metallic enamelsIn the case of metallic enamel coating, variations in colour may occur between different production batches. For this reason it is advisable to take care when planning facades or visible roofs to make sure that the profiled sheets are roll for-med from the same batch of material.

Anti-condensation andanti-drum coatingsIf required the profile sheets can also be fitted with an anti-condensation or anti-drum coating.

Kalzip range of applications

4. Kalzip range of applicationsWithin the context of the amendment of the German energy saving regulations (EnEV 2009), the energetic requirements of exter-nal structural components are an important component of the new energy saving regu-lations for improving the sustainable energy efficiency of buildings in the context of economic viability and in accordance with the state of the art.

On the basis of newly-developed materials, Kalzip system components make a signifi-cant contribution to EnEV-compliant roof structures.

Application specific system build-upKalzip sheets can be used both for venti-lated and non-ventilated roofs as well as for any roof shape or down to a minimum pitch of 1.5°.

Furthermore it may be combined with any kind of support or substructure. The system depends on the special requirements of the individual application.

The likely effects of snow, wind, humidity and weathering are fully taken into account. Kalzip can easily be configured to provide the highest levels of thermal insulation.

Thermal insulation requirements can be easily fulfilled. The thickness of the insu-lation can be perfectly adapted to the individua lrequirements of the building. In addition, the system offers advanced detailed solutions for effective interior or exterior draining of the roof which means a high degree of reliabilty throughout the long serviceable life of the roof.

Insulated roof systems are the norm The main applications for Kalzip roof systems are insulated roof structures supported by trapezoidal steel, timber linings, purlins or concrete elements. • Chemically neutral, fibrous insulating

materials as specified by e.g. the German DIN 18 165 are recommended as suitable thermal insulation. The insu-

lation is laid into position and is then compressed to its required final thick-ness when are installed the profiled Kalzip sheets on top. There should be no cavity between the Kalzip sheets and the insulation.

• A vapour barrier must be incorporated. Properly installed it provides the

required air tightness.

• Of course, ventilated roof implementa-tions are also possible

• The sound reduction values of the standard roof are subsequently described. Further improvements can be achieved by including additional layers.

• Information on U values can be found in chapter 7, Kalzip dimensioning tables, starting from page 47.

Non-ventilated Kalzip roof on a trapezoidal steel deckR’w = ~ 35 dB (A)*

Non-ventilated Kalzip roof on a trapezoidal steel deckThis very economical roof system is used both for industrial and residential buildings. In order to make sure that there are no air cavities under the Kalzip roof skin, compres-sible thermal insulation is used. Incorpo-rated within the roof system the insulation material is compressed by approx. 20 mm.

The loading on the top skin is not transfer-red to the inner skin as an evenly distributed load but rather at set points via the secret fixing clips. The design roof load must be increased by 15 % when dimensioning the trapezoidal steel sheets. The clips must be staggered on the inner sheet to make sure that the load is evenly distributed across all corrugations of the inner sheet.

* varies depending on thickness and material qualities

Page 17: KALZIP Roof Technical Brochure

Kalzip 17

Kalzip range of applications

Non-ventilated Kalzip roof on purlins with trapezoidal inner sheetIf the roof is supported on purlins, the in-ner sheet has to be oriented parallel to the top layer. If the module of the inner sheet does not correspond with the Kalzip ele-ments a top hat section must be installed to support the clips. If the Kalzip sheets can span the existing spacing of the purl-ins, the top hat sections will be positioned on top of the purlins. By this way the inner sheet carries only the weight of the insu - lation.

For larger purlin spans additional top hat sections are required. In this instance, part of the load needs to be transferred by the inner sheet.

Non-ventilated Kalzip roof on timber rafters with visible timber liningIn residential buildings the roof system is frequently built-up using wooden rafters with visible timber lining. This is advanta-geous, because:

1. there is a clear separation between the trades of carpenters, roofers etc.

2. a continuous flat vapour barrier can be installed.

The clips can only be fixed directly in the timber lining if this has a minimum thick-ness of 23 mm. A minimum thickness of 19 mm applies for flat press boards, and 18 mm for OSBs. In both cases the fastener is visible from below. If the timber lining is too thin, then a timber purlin must be installed over the lining and attached to the rafters. See Kalzip approval No. Z-14.1-181.

* varies depending on thickness and material qualities

Kalzip range of applications

Kalzip DuoPlus 100 and Kalzip Duo 100 on a concrete substructureThe Kalzip DuoPlus and Kalzip Duo system can likewise be installed on a concrete sub -structure. In the case of a solid concrete slab, the DuoPlus rails can be arranged at a 90° angle to the Kalzip. The rotary clip rails are fixed using approved dowels (SFS MBR-X-S4-HX-10x160). The dowels are arranged alternately in the rails. The distance bet-ween the rails depends on the static calcu-lation. In the case of slabs made of porous concrete or non-solid concrete slabs, the DuoPlus rails are arranged at an angle of less than 45° to the Kalzip. The dowelling possibilities must be precisely checked in each individual case and statically calculat-ed. The choice of approved dowels must be matched precisely to the concrete material.

Kalzip DuoPlus 100The Kalzip DuoPlus 100 system combines the advantages of rigid insulation with the constructional possibilities offered by the conventional Kalzip roofing system. The special design is almost cold-bridge free and has excellent sound absorption proper-ties. An aluminium rail is placed on the 100 mm thick rigid thermal insulation and is fixed onto the substructure through the insulation. Special clips are inserted in the rail and are adjusted to suit the respective conditions. Connection of the individual clips to the rail is not necessary. The paten-ted and type-tested system consists of rigid thermal insulation, DuoPlus rail, Duo-Plus clip and connecting elements to secure the DuoPlus rail, the compressible heat insulation and the Kalzip profiles sheets.

Kalzip DuoPlus 100R’w = ~ 43 dB (A)*

Kalzip Duo 100If there are no specific sound insulation requirements then the Kalzip Duo 100 system can be used, whereby a full layer of rigid thermal insulation is not necessary. The base for the Kalzip DuoPlus 100 is simply provided by rigid insulation strips with a width of 24 cm and a thickness of 10 cm. The resulting spaces are filled with soft heat insulation or low-priced rigid insulating material. In the case of Kalzip DuoPlus 100, rigid thermal insulation only needs to be used in those areas specified by the statistical requirements. The rigid thermal insulation is replaced by a layer of soft insulation in all areas where no reduc-tion in snow loads is required.

Kalzip FOAMGLAS® System as a standard and combined solutionThis roof design and the system com-ponents used are particularly suitable for building projects which place high demands on ensuring that the roof sys-tem is free from condensation and where there is therefore a permanent risk of condensation formation. The Kalzip FOAMGLAS® System offers a high level of energy efficiency as the thermal insulation is airtight and impervious to water vapour. What’s more, there is no mechanical at-tachment between the Kalzip profiled sheets and the supporting structure. This means there is no coldbridging. As FOAMGLAS® is impervious to moisture penetration the insulation can also act as a watertight substructure.

The FOAMGLAS® slabs are bonded to different substructures using either a cold-bonding agent or hot bitumen. In order to attach the composite clips, the galvanized steel claw plates are inserted under heat in a fixed installation plan taking into ac-count the respective roof geometry. The composite clips are installed on the claw plates using the recommended fastening elements. The Kalzip profiled sheets are installed in the usual manner and are fric-tion-fitted together. In order to ensure economic efficiency, the thickness of the compressible thermal insulation can be varied. FOAMGLAS® has a minimum thick-ness of 80 mm.

The manufacturer’s installation regulations are to be observed. The installation and di-mensioning are governed by the Kalzip ap-proval Z-14.4-475.

Kalzip AF profiled aluminium sheets are especially designed for installation above rigid support layers. Under the trade mark “ProDach insulating system” Rockwool offers an accessible, compression-proof, water repellent mineral wool insulating board featuring a special fixing system. Kalzip AF is available in sheet lengths up to 50 m (longer lengths are available on request).

The level ribless profile provides a smooth and attractive appearance. The AF system offers outstanding thermal as well as acoustic properties. Kalzip AF profiled aluminium sheets are not only used in

combination with the ProDach-insulation system but may also be used with FOAM-GLAS® insulation and timber lining.

The twin layer Prorock insulating board: the ideal base for Kalzip AF• non combustible • very efficient thermal insulation and acoustic properties• dimensionally stable • vibration dampening• open for diffusion• high accessibility during installation and maintenance • safe absorption of pressure and suction loads

AssemblyThe corrosion-proof and weather resistant Kalzip AF aluminium external skin is fixed with clips in the usual way. How ever, and this is the distinctive feature of the ProDach insulation system, rather than being fixed directly to the substruc ture the skin is fixed instead to special U-rails embedded in the insulation material.

The stainless steel system fasteners con-necting the U-rails to the substructure of the roof penetrate the insulation material only locally. This almost entirely eliminates the effect of cold/heat and sound bridging.

Kalzip AF with ProDach-insulation on trapezoidal steel deckIn order to meet increased demands for sound reduction and to reduce cold/heat bridges it is advisable to install the ProDach Insulation System. Fixing rails are embedded in the top-side of the insulation material and fixed to the trapezoidal steel deck.

Kalzip AF with ProDach-insulation on timber rafters with formworkWith this type of roof, a timber lining which remains visible serves as a supporting element. This structure has proved to be ideal for residential buildings and other buildings of similar use. The potential extends from public buildings to multi-pur pose halls and sports-arenas. The rails are invisibly fixed to the rafters. There are no visible joints or fasteners.

Kalzip AF with the insulation layerat rafter level*This structure is comparable to tradi tional standing seam systems. It is frequently used in order to minimise the overall height of the roof structure. If there is an air gap under the timber lining adequate ventilation is essential.

With this in mind, we recommend filling the total height of the rafters with insulating material for efficient performance. A vapour barrier beneath the thermal insulation is also of critical importance.

For the minimum thickness of timber ma-terials, see Kalzip approval Z-14.1-181.

Kalzip AF on FOAMGLAS® insulation*Kalzip AF can also be used on the proven FOAMGLAS® insulation. Various installation methods are possible. The method shown here using the L-shaped claw plate does entirely without a mechanical connection between the Kalzip profiles and the sup-port skin and is free of thermal bridges. The composite clips employed allow opti-mum sliding of the profiles in the case of a temperature-related change of length.

A thermally stable isolation layer must be arranged between Kalzip and a bituminous secondary covering.

When referring to photovoltaic systems, architects make a distinction between roof-mounted and roof-integrated systems. Kalzip GmbH offers solar power systems which are perfectly coordinated with Kalzip for both options.

Because of the small dead weight and the lack of structural height, the additional load on the main support structure remains very low, which positively affects the costs of the building. These advantages are par -ticularly effective in the case of renovation measures. The problem of the existing support structure not being able to absorb additional wind and snow loads, which frequently arises with crystalline systems, usually does not arise with Kalzip Solar systems. The necessary static examination of the existing building can often be omit-ted due to the low loads.

Kalzip AluPlusSolarThe new Kalzip AluPlusSolar profiled sheets are the first to combine a system of solar power generation using roof-integrated photovoltaics with the maximum freedom of architectural design to create stunning buildings. The solar laminates are flexible and extremely durable. Depending on the particular roof design, they are permanent ly bonded to straight, convex or concave Kalzip aluminium profiled sheets. The flexi-bility of Kalzip AluPlusSolar can accom-modate barrel vault or monopitch roofs, as well as customised roof designs.

Kalzip AluPlusSolar is available as a fully integrated system, including inverter and accessories, on the AF 65/537/1.0 mm

profiled sheet in RAL 9006 (other colours available on request). The solar film, avail-able in two lengths, is laminated in the factory and then permanently bonded to the outer surface of the Kalzip profiled sheets. This film will subsequently gene-rate the power in the photovoltaic system. Kalzip profiled sheets which have already been installed cannot be retrofitted with laminated solar film. However, existing Kalzip roofs can be retrofitted with Kalzip SolarClad. In addition to a roof-integrated, regenera tive method of energy production, Kalzip SolarSystems also offer the oppor-tunity of generating energy in the facade. We can send you detailed information on request.

The silicon thin-film solar cells use triple-junction technology to generate more energy in diffuse light conditions than crystalline solar cells of the same rated power and are therefore ideal for use in

European regions. The durability of the Kalzip profiled sheets and the guaranteed efficiency of the solar modules now make it possible to create contemporary, modern buildings which combine maximum freedom of architectural design with the integration of ecological concepts.

Planning tips• Kalzip profiled sheets cannot be retro-

fitted with laminated thin-film solar modules. We recommend the use of Kalzip SolarClad.

• Minimum radius in the area where the rofiled sheets are fitted with modules 13 m.

• Recommended roof pitch min. 5 % (3°).

Kalzip range of applications

Kalzip SolarCladKalzip SolarClad is a photovoltaic cladding which has been optimised for use in buil-ding envelopes. Its flexibility and versatility enable solar modules to be integrated into virtually all standing seam systems made from a variety of materials. Kalzip Solar-Clad is a retrofit solar solution which can be harmo niously integrated into existing building structures and also used in new builds.

The system consists of extremely robust thin-film modules made from amorphous silicon (a-Si), bonded onto aluminium sys-tem rails, which can be installed on any metal roof system in a non-penetrative manner. These extremely lightweight mo-dule units are suitable for all roof shapes.

Kalzip SolarClad is supplied as a com plete system, including inverters, for different standing seam designs. The solar film, available in two different lengths, is lamina-ted onto Kalzip system rails in the factory to ensure high quality and fast installation. The solar laminates generate power from the sun as soon as they are connected. Kalzip SolarClad is suitable for all roof shapes with a pitch up to a maximum of 60° from horizontal. As the system is ex-trem ely lightweight, this generally means there are no additional structural require-ments for the roof. Kalzip SolarClad is therefore suitable for all roof structures and all Kalzip widths.

General data and characteristics

5.1 Roof pitch

The Kalzip system consisting of self sup-porting aluminium elements was specially developed for roofs with pitches down to 1.5° or 2.6 % together with long sheet lengths. Owing to the attractive appea-rance of the modular system, architects often use this system for visible steep roofs and increasingly for wall claddings.

Continous falling gradient requiredAll parts of the roof must have a conti nous downward gradient towards the draining system.

Minimum roof pitch• without horizontal joints 1.5° respectively 2.6 % - running from the eaves in one length - all joints are welded - factory welded soakers welded into

the roofing skin

• sheets with horizontal joints 2.9° (5%) - with sealed horizontal joints - soakers sealed into the roof skin - Factory welded soakers sealed into

the roof skin

AnomaliesThe specification limiting the minimum roof slope is not applicable along the ridge area where roof elements run with out joints from eaves to eaves over the ridge.

5. General data and characteristics5.2 Minimum radii for crimp-, smooth- and on site curving

Exacting design calls for creative and de-tailed solutions. Today curved corners or arched roofs can be easily achieved by advanced industrial prefabrication. They provide modern industrial architecture with a high level of functional and aesthe-tic quality combined with future oriented perspectives.

The minimum radii for smooth curving of Kalzip elements are specified on the following page.

Installation width is the actual width of the assembled sheets. If the clips are pre-installed the installation width must be increased. (Installation width = cover width + 3 mm)

If crimp-curved profiled sheets are connected with straight ones, the rounded sheet determines the dimension. It is recommended to carry out the distribution in accordance with the measured dimensi-on of the rounded profiled sheet.

General data and characteristics

General information

Kalzip AF und AS:With Kalzip AS and AF profiled sheets, an in -crease in construction width of up to 20 mm must be taken into account following cur-ving, so that an overlap with straight sheets is not possible.

Smooth-curved Kalzip AF profile sheets can show signs of increased buckling in the base plate. As it is impossible for tech nical production to prevent this buckling, it will not be accepted as grounds for complaint. When the optical characteristics of a buil-ding are of increased importance, then smooth-curved Kalzip AS profile sheets should be used instead.

Standard:Constant radius with a short (approx. 400 mm) straight segment at the beginning and the end of the profile sheet. Any radii below the standard minimum as well as multiple radii and/or straight elements in one Kalzip sheet must be agreed with our technical department in Koblenz.

It is unavoidable that inter mediate radii occur in the transition area of different radii as well as between curved and straight sectors. Clips must not be located in these areas.

Tolerance limits. Only after consultation with our technical department in Koblenz. Special measures are necessary in order to reach the tolerance limits.

Finish:• stucco-embossed• AluPlusPatina• coated material with protection foil• AluPlusZinc with protection foil • Anti-condensation coating on request

Installation width:For pre-installed clips: cover width + 3 mm successive installation of clips: cover width + 0 to + 3 mm

Length of profiled sheet:Minimum length 1.5 m. Shorter lengths on request. The final overall length depends on the individual radii and possibility of transport. Minimum length of segment per radius = 500 mm.

Transportation:Maximum loading height 2.4 m. It might be necessary to coordinate details of trans-portation with our logistics department.

Transitional area:If a Kalzip profiled sheet is roll-curved with several radii, a transitional area is created in which no clip may be placed (except a fixed point clip).

This transitional area can be safely estima-ted to be ± 300 mm (600 mm in total) if the two adjacent radii both have the same sign has, or ± 600 mm (1200 mm in total ) if the two adjacent radii have different signs, i.e. from concave to convex or vice versa. It is necessary to consult the Application Tech-nology Dept. in Koblenz for a more exact determination of this transitional area.

General information

Naturally curved:The profile sheets are supplied in straight form and are curved by hand to the res-pective radii during installation.

Cover width:Depending on the radius, the nominal width (construction width) must be increa-sed to the cover width (installed width).

Support spacing:When the supporting spacings are too large the supports will appear as polygon lines.

Accessibility:Due to the risk of buckling, access to the sheets must not be gained without load spreading equipment.

Appearance:The minimum radii outlined above reflect current experiences. As it is necessary to curve the profile sheets to the respective radius, buckling cannot be ruled out.

Installation tip:It is advisable to provide a support on the ridge over which the profile sheets can be curved. Installation should take place from the direction of the non-covered side.

Packaging:If the pitch is greater than 1.70 m, then this information must be supplied when ordering. The reason for this is that spe-cial packaging may be necessary.

5.3 Tapered shapes

Tapered Kalzip profile sheets have become increasingly significant for roofing appli ca -tions as they can be formed into a diverse range of shapes. A roof can offer more than just protection: it can enable a build-ing to achieve architectural perfection. In order to achieve the perfect structure, it is necessary to take into account several fundamental considerations. The cover widths are between 230 and 740 mm. Fur-thermore, accessibility is limited.

The bottom sheet must be additionally supported by rigid insulation. Load distri bu-ting walkways must be provided. In order to ensure that the bottom sheet is ade-quately rigid, it is essential to incorporate an eaves angle.

The full surface is always covered with foil. Anti-condensation coating is only subse-quently available in the spraying process. Aquasine coating is not possible. Tapered Kalzip sheets must be installed on the roof in accordance with the installation instruc-tions. It is advisable to compare the actual dimensions of the substructure with the dimensions stated on the installation in-

structions before production in the factory begins. Larger building tolerances can require repartitioning of the area which is to be covered. The tables on the following page apply to a sheet width of 500 mm.

5.4 Kalzip XT free-form profiled sheetsKalzip type 65 /… / 1.0 mm

The XT production technology allows diffi-cult roof and wall surfaces, even if they are free-form surfaces, to be clad with Kalzip profiled sheets. Different radii, convex and concave, as well as side radii, bulges and narrowings can thereby be combined in one profiled sheet.

The limit values are subjected to constant changes and improvements. The combina-tion of the various possibilities in particular has a big influence on the various limit values.

The following, non-binding limit values serve as an aid to orientation:Convex curved 2.50 mConcave curved 10.0 mSide radius 20.0 mMinimum width 275 mm*Maximum width 740 mm*

The maximum length depends on the transportation possibilities and the basic material available. The minimum length depends on the contour and on the pro-duction procedure and must be examined in detail.

For reasons related to production, excess lengths of at least 400 mm are necessary at the ends of the XT profiled sheets; these have to be cut off on the building site. They offer additional flexibility in the alignment of the profiled sheets.

The quality of the finished Kalzip surface depends to a large extent on the quality of the spacer structure between the sup-port structure and the outer skin. It must be adjustable in order to be able to com-pensate for building tolerances.

The planning and installation of XT pro-filed sheets requires a great deal of effort.

XT constructions are planned completely in 3D. A 3D GUI, preferably in the format .3dm (Rhinoceros), is necessary for editing. The suitability of other file formats must be checked.

5.5 Accessibility/fall arrest systems

For maintenance and cleaning Kalzip sheets are accessible both during and after installation without any load distributing measures. As far as the installation is con -cerned this will only be valid if the profiled sheets are zipped on at least one side. The following table specifies the critical spans up to which the profiled sheets are acces-sible without any additional measures.

It is advisable to install walkways leading to any units requiring regular maintenance or operational elements such as daylight units, chimneys or heating plants. When exceeding the critical span, load distribu-ting elements such as wooden planks of a minium cross section of 4 x 24 cm and a maximum length of 3 m have to be installed length – or crosswise over the Kalzip sheets.

In situations where no rigid thermal insu-lation has been installed along the ridge and eaves areas, the sheets in these parts of the roof should not directly be walked on. The reason being that this might lead

to deformation of the flat area of the Kalzip sheet resulting in a possible accumulation of rain water.

The last free sheets along the gable end, single unzipped sheets and of course translucent panels should not be walked on. During the installation of the roof any areas which are frequently walked on or used for the transport of materials should be protected by temporary walkways, which should be secured with seam clips to prevent them from sliding down.

The Kalzip fall arrest system is a reliable solution to secure walkways on the fin-ished roof. It consists of a stainless steel rope which is fastened to permanently fixed Kalzip roof anchors and coupled to the safety harness by means of a guide link. Project related planning is carried out by Kalzip GmbH.

5.6 Material/corrosion resistance

An essential advantage of Kalzip sheets is the lightness of the aluminium material. Seawater proof alloys are used as basic materials. Protection by natural oxidationDue to the natural formation of a protective coat of oxide, Kalzip profiled aluminium sheets are reliably protected against cor ro-sion when exposed to normal weathering by maritime, continental and industrial atmospheres. With plated material this effect is even greater, as the plating acts as a sacrificial anode protecting the core material against corrosion for many years. If, however, the roof is exposed to a highly aggressive atmosphere occurring in the immediate vicinity of the building, for in-stance, industrial premises such as copper plants emitting high levels of aggressive chemicals; appropriate resin coatings with a minimum thickness of 25 µm will provide lasting protection. Contact corrosion In contact with other unprotected metals and under the influence of humidity, alu-minium produces an electrochemical con-tact element, which may lead to corrosion. The annexed table is the result of extensive tests and investigations carried out in Sweden and proves that the Kalzip alloy can be combined with most of the com-mon materials used for building purposes without the risk of corrosion.

Protective measures to avoid contact corrosion are • plastic coating• neutralizing the steel surfaces for

instance by hot-dip galvanizing• interrupting the metallic conductive

contact by applying a primer or by in-corporating a suitable separation layer

Installation in combination with different materials

Steel:Direct contact between the profiled alumi-nium sheets and unprotected steel parts of the substructure must be avoided due to the likely risk of contact corrosion. There are a number of different protective meas-ures such as plastic foils, interme diate layers coated with bituminous, zinc chro-mate or chlorinated rubber paint or the galvanizing of the contact areas of steel parts.

Timber:Timber parts in contact with Kalzip should be dry. For the protection of timber rafters and other wooden construction elements in direct contact with aluminium structures only compatible (f.i. oil based) wood pre-servatives must be used. They must not belong to the group of naphta lenic chlorines and must not contain any copper, mercury salts or fluorine compounds.

Concrete and mortar:Any direct and indirect contact with con-crete and mortar must be avoided. The concrete/mortar must be set and must not be damp. As dampness can never be completely ruled out, it is always advis-able to separate concrete and aluminium profiled sheets by means of a suitable intermediate layer. Do not allow drilling dust to get onto the aluminium surface; if this does occur, ensure that the dust is immediately and carefully removed.

5.7 Sustainable construction

Aluminium – functional and long-livedAluminium contributes substantially to the effective protection of buildings against external influences over many years and to the retention of their value. Kalzip alu-minium roof and façade systems have been used for 40 years worldwide as a preferred solution for building envelopes.

One of the outstanding characteristics of the material is its resistance to weathering and the associated durability. This result in security and retention of value, in particular when high demands are placed on the use of the buildings e.g. at airports or in demanding locations, e.g. near the coast.

The material for Kalzip has been submitted to increasingly critical tests over the course of the time, including an examination by the BAM (Federal Institution of Materials Testing and Research) of the improved weather resistance of plated Kalzip profiled sheets after nearly 40 years of exposure.

Sustainable construction with aluminium building envelopesThe introduction of certification systems such as Breeam, Leeds and DGNB has for the first time provided evaluation crite-ria for sustainable planning and building, which urge us to use our resources res-ponsibly and hence to contribute decisi-vely to the protection of the environment.

The building and property business in particular can make a decisive contribution to the sustainable development of our society, because around 40 per cent of worldwide CO2 emissions are caused by buildings (source: DGNB)

The planning and construction of buildings will demand integrated solutions in the future. The entire lifecycle of the building must be considered. Sustainable construc-tion aims at a minimisation of the consump-tion of energy and resources as well as the lowest possible impact on the ecologi-cal balance in all phases of the lifecycles of buildings – from the planning, construc-tion and use to the renovation and demo-lition. All individual measures for the mini-misation of the energy consumption and use of resources must be optimally coor-dinated with one another and external in-fluences must also be considered.

Sustainable construction means conscious planning and construction. A comprehen-sive quality concept, which is already applied during product evelopment at Kalzip, is particularly effective here and serves both the building industry and our society. The influence of sustainability is at its greatest during planning.

The lynchpin of the Kalzip sustainability is the aluminium itself, a material that can

be recycled any number of times and is sufficiently abundant: It is the most com-monly occurring metallic element on Earth.

Three-quarters of the aluminium ever pro-duced is still in use today. Approximately 95% of aluminium from the roof is recyc-led. The recycling of Kalzip profiled sheets and other aluminium products requires 95% less energy than the primary produc-tion from bauxite, without loss of quality. This avoids approx. 80 million tonnes of greenhouse gases worldwide per year.

Kalzip is a member of the association for sustainable construction, the DGNB.

General data and characteristics

5.8 Offi cial approvals/design calculations

The use of Kalzip roofing elements is subject to the official building regulations. Proof of stability and the suitability for use must be provided in each individual case. The basis for the design calculations is always the German Inspec torate Approval No. Z-14.1-181 issued by the Institute for Building Technology. Kalzip is officially approved by many European building authorities and is subject to continuous monitoring. This includes a description of technical characteristics, materials and dimensions. The stipulations for design and measure-ment contain information on design loads, static systems and safety values. The stipu-lations on specification govern, amongst other things, roof pitch, edge design, accessibility, technical expertise/training requirements of the installers. The appen-dices contain tables relating to standard details and characteristic values for the proof of stability and suitability for use. For frequently recurring applications you

will find load-span-tables, from which the maximum spans under practical wind- and snow loads can be extracted. So the proof required by law can be easily pro-vided at any time.

5.9 Transport

When designing unusual special roof shapes (for instance, long profiled sheets with small curving radii) the feasablity of transportation has to be checked with our logistics department. The dispatch department at the pro duction factory is available to advise you here. Permits are required from the local road authorities for the transportation of lengths of 18 m and more. When extreme lengths are to be transported, it is essential to allow for the time required to obtain permits from the local road authorities.

5.10 Sheet thickness

According to the licensing agreement issued by the building authorities the mini-mum thickness for Kalzip profiled sheets is t = 0.7 mm. Although these sheets are accessible both during as well as after their installation for main tenance and cleaning without the need of load distributing measures, it is however not advisable to use sheets of this thickness because of the risk of denting resulting from people walking on the sheets during installation. For aesthetic reasons it is advisable to choose a minimum sheet thickness of 1 mm on any visible areas.

Design specifications

6. Design specifications6.1 Moisture proof

For insulated roofs and walls it is essential to provide sufficient protection against condensation in each and every case. In this context vapour diffusion (e.g. accor ding to DIN 4108-3) as well as air flows must be considered.

Superficial formation of condensate on structural componentsIf the minimum values of heat transition resistance according to DIN 4108-2 are observed, a verification of the protection against condensation in non air-condi-tioned rooms such as residential premises and offices is generally not required pro-viding that these rooms are adequately heated and ventilated according to the normal standards.

In special cases for instance with perma -nent high humidity levels it is necessary to calculate the required heat transition resistance in relation to the actual internal climatic conditions.

Formation of condensate inside multi-layer constructionsA vapour barrier must be installed in order to prevent vapour from penetrating from humid internal rooms into the roof con-struction. In wall structures vapour barriers are generally not necessary. To prevent humid internal air from diffusing into the roofing system, an airtight barrier must be installed, which is fully sealed at all joints to the adjacent structures, as required by the Energy Saving Directive. A professionally fitted Kalzip vapour barrier meets these requirements.

6.2 Ice barriers

In some regions where exceptionally severe weather conditions can be experienced, ice barriers can form on metal roofs with certain structural features. These are block-ages or plates formed from snow, melt water or rainwater which have frozen toge-ther and can impede the flow of water on roofs.

Known regions include:• the Alpine region• the Central German Uplands• other areas which have a high snow fall

Structural features which have led to ice barriers on roofs:• Shaded areas created by additional fitting or structures• Cold roof overhangs • Complicated roof shapes, a multitude of fittings or structures• Guttering and downspouts which can freeze up (bends, no gutter heating)• Accumulated snow, uneven distribution of snow on the roof• Linear snow guard systems• Fall arrest systems with cable

connections• Lightning conductors• Walkways• Discontinuities in the thermal insulation effect• Thermal bridging• Poor workmanship (defective connec tions on penetrations or roof edges, defective vapour barriers in the case of warm interior rooms)

Exceptional weather conditions experienced in recent winters:• Rapid and frequent alternation between freezing/thawing • Catastrophic snow quantities• Frost coldness and snow at the same time

If ice barriers impede or stop the flow of rainwater or melt water above guttering there is a risk that the water will accumu-late and enter the attic area and therefore the building through the joint overlap of the profiled sheets.

Those areas of the roof which are at risk include, for example, channels, single-skin roof overhangs, areas which are partially roofed and shaded areas.

Standing water must be avoided on metal roofs. For this reason, these roofs must always be sloping. This is to prevent the loading capacity of the roof covering from being exceeded and the roof from col-lapsing as a result of the load exerted by standing water.

For this reason, the values given in the standards and in the directives for roof pitches stipulated by the building authori-ties must be observed on all points of a roof as a minimum.

Furthermore, metal roofs which have longi-tudinal and cross joints or overlaps which have not been welded or soldered, will not be watertight (against “pressing water”), but only rainproof. This means that when accumulated water exceeds a specific level it will penetrate via the joints and connec-tions. This is another reason why a minimum pitch must be maintained.

Standing water on roofs may not only be caused by inadequate roof pitches but also as a result of other factors. For example, as a result of blockages in the flanges on the profiled sheets which carry the water, in the case of superstructures or projections which have been incorrectly designed or installed or when ice barriers have formed.

An essential planning task is to ensure that ice barriers are avoided. Various measures can be recommended. However, no list of recommendations can be regarded as complete. As the effectiveness of recom-mended measures depends on local con-ditions, these measures can only be regar-ded as suggestions and do not release the company carrying out the work from the obligation to check feasibility. No liability can be accepted for this.

In view of the experiences of the particularly catastrophic snow conditions experien ced in winter 2006, it should be noted that absolute safety against ice barriers cannot be guaranteed.

Page 34: KALZIP Roof Technical Brochure

34 Kalzip

Design specifications

Planning and constructive measures: • Roof projections should be avoided or at least insulated• Shaded areas should be avoided or heated• Areas at risk should be equipped with roof heating• Substructure should be installed at least 3 mm towards the inside of the roof and connected at the gutter• Flow directions/roof pitch should not be directed into cold roof areas• Gutters should be heated, particularly internal structures• Bends in downspouts should be avoided• Keep downpipes free, service gutters and downpipes• Direct gutter heating into the downpipes

right through to the frost-free ground area

• Be aware of the risk of suspended gutters breaking away• Ensure snow remains evenly distributed on the roof (use a lot of individual snow

guards rather than just a few linear sys-tems)

• Connect vapour barrier to gutter, use as an emergency downspout?• Fall arrest equipment, walkways and other obstacles should be protected by snow guards to prevent snow and ice from collecting• Thermal bridges should be minimized or completely avoided• Large discrepancies in U-values should

be avoided.

The planner must check that individual measures are adequate or whether the com-bination of several measures is required in order to achieve adequate efficiency. If ice barriers have occurred and these are to be avoided in the future, then the following measures can be successful – depending on the causes. However, there can be no guarantee of absolute safety here:

• Long joints should be avoided, e.g. through welding or masking• Panel heating should be installed (gutter heating should always be available)• Linear snow guard systems should be redesigned and either replaced by systems which provide a more even distribution of snow or supple- mented by additional systems.

• Accumulated snow should always be removed as quickly as possible. Snow and ice should be cleared away.

In the case of each of these measures, the specific conditions of the individual building in question must always be taken into account. For this reason, it is not possible to make general statements.

6.3 Sound absorption

Highly efficient sound absorption can be easily achieved with Kalzip roofs by con-structive measures such as incorporating additional layers, while all benefits of the lightweight constructions remain unaffected.

6.4 Fire protection

The demands concerning fire protection of building materials and structural parts etc. are specified in the local building regu-lations. According to DIN 4102-4 aluminium alloys are classified in category A1 (”not inflammable“) without special verification. Kalzip profiled sheets – even with organic coatings on both sides and with class B insulation layers underneath – are classi-fied as resistant against flash-over and radiating heat without any special verifi-cation (“hard roof covering“).

6.5 Lightning protection using Kalzip aluminium profiled sheet envelopes

Economic and efficient protection against lightning strikes and their effects can be achieved by using Kalzip systems:• As a lightning arrest or conducting

device to prevent lightning strikes affecting the structure

• As a protective screen to counter the electromagnetic effect of lightning strikes

When installing Kalzip roof or wall clad-ding systems there is generally no need for dedicated or additional lightning pro-tection devices. The calculated probability of structurally damaging lightning strikes is once in every 500 years. Such a strike hitting a Kalzip clad building would cause, at worst, no more than a small hole in one of the sheet seams. Damage of this na-ture would lie above the line of weather-ing and could be easily sealed again with no risk of damage to either the sub-struc-ture or to the rest of the Kalzip cladding.

Kalzip as a conductor of lightningAccording to the lightning protection standard BS EN 62305-3 or VDE 0185-305-3 ‘Protection against lightning - Part 3: Physical damage to structures and life hazard’, metal roofs are suitable as ‘natu-ral arresters’ for lightning protection.

In the table in Supplement 4 of this stand-ard, ‘Use of metallic roofs in lightning pro-tection systems’, it is specified that un-coated metal roofs whose roof elements (profiled sheets) are connected by folding (Kalzip foldable aluminium in the finishes FalZinc and Titansilver) or by flanges (Ka-lzip profiled sheets in the finishes stucco embossed, mill finish, AluPlusZinc or Alu-PlusPatina) are suitable for use as a natu-ral component of a lightning protection system without further requirements.

Roof elements that are bolted or riveted to one another (trapezoidal and corrugat-ed profiles) for use with and without an organic coating are suitable without fur-ther requirements. The same applies to welded profiled sheets. Type testing is re-quired if the flanged or folded roof ele-ments are coated. Kalzip has passed this examination in accordance with report BET/Corus 08-06-17-1d issued by the BET Blitzschutz und EMV Technolo-giezentrum - OBO Bettermann, D-58710 Menden.

Hence, roofs made of Kalzip profiled sheets are suitable without further re-quirements for use as a natural compo-nent of a lightning protection system.

The same applies to standing seam roofs as well as trapezoidal and corrugated profiles. The prerequisite for this is that the roofs are capable of conducting cur-rent, e.g. they are connected to ground via approved lightning conductors from OBO Bettermann GmbH (www.obo.de).

Technical requirements for lightning conducting devices:• The Kalzip sheets must be conductively

connected to earth• The seams of the Kalzip sheets must be

fully zipped to ensure contact• There must be conductive connection

of the roof sheets to: - a conductive wall cladding (metal) - a steel or aluminium sub-structure - any concrete sub-structure must be

reinforced

Construction details relating to these requirements should be checked with a lightning protection specialist.

Figure 3. Cross section showing connection and earthing across the structure.

Figure 1 Kalzip as a conductor of lightning

Figure 2 Kalzip as protective screening

Page 36: KALZIP Roof Technical Brochure

36 Kalzip

Design specifications

Kalzip as protective screeningIf the complete building envelope consists of aluminium (Figure 2 on page 35), i.e. Kalzip systems used for both the roof and wall cladding, the envelope will halt and collect the electrical energy from lightning and safely conduct it to earth thereby pre-venting dangerous voltages from affecting the power supplies.

IT networks and electronic control systems connected to the mains power supplies will be safely protected from damage and in most instances there will be no need for additional protective devices.

For optimum screening, the Kalzip profiled sheets right across the building envelope should each be con-ductively connected to earth and any larger openings in the building should be by-passed. Tests on Kalzip installations have shown that, de-pending on the design of the screening, the electromagnetic field inside the system, corresponding voltages and strength of current, are reduced by a factor of more than 100.

Technical requirements for protective screening• The envelope of the building must be

completely conductive at all points and connected to earth (Figure 3).

• Kalzip must have a metal finish (stucco-embossed, AluPlusZinc or mill finish).

• Where coated Kalzip sheets are used: - the ST Clips must be secured to a

metal substructure - on timber substructures, the ST Clips

must be connected with aluminium strips (minimum 60 mm wide and 0.7 mm thick) below the sheeting.

• At the Interface between roof and walls, each and every profiled sheet must be connected using short aluminium strips (minimum 50 mm wide and 1.0 mm thick).

• Window openings should not exceed 1.5 m x 1.5 m. Larger openings must be by-passed using aluminium strips (mini-mum 50 mm wide x 1 mm thick) or must be connected to the wall substructure by means of aluminium frames, in which case no other conductive structural connections are required.

Construction details relating to these requirements should be checked with a lightning protection specialist.

6.6 Roof systems

6.6.1 Rafter roof: Kalzip sheets perpendicular to the trapezoidal steel deck

A supporting trapezoidal deck forming the substructure of the roof spans from rafter to rafter running parallel to the eaves. The clips are either fixed directly to the top corrugations of the deck or indirectly by means of spacers. The fixing points are visible underneath the supporting steel deck. The clips are diagonally distributed on top of the steel deck, so that all corru-gations of the deck are load bearing. The clips must be located following a special pattern to ensure even load distribution on the trapezoidal steel deck both in the case of positive loads (due to snow) or negative loads (due to wind or aerodynamic suction).

Page 37: KALZIP Roof Technical Brochure

Kalzip 37

Design specifications

• A continous row of clips is to be fitted along the ridge and the eaves.

• In between the clips are arranged diago-nally. Distances depend on the design loads, the Kalzip sheet widths, the pitch of the ribs and the support spacing of the trapezoidal sheet underneath.

• The number and positioning of the clips as well as the joining elements are indicated in the assembly plan.

• Depending on the likely loads it may be necessary to halve the spacing of the clips at the corners and along the edges of the roof.

(See dimension tables)

6.6.2 Kalzip perpendicular on timber lining

The clips are fixed directly to the timber lining. The clips must be positioned on the timber lining in accordance with positioning diagram 1 or 2. If the clips are to be posi-tioned next to each other, then the timber board and its attachment to the substructure must be statically verified. A carpentry attachment is not sufficient.

Determination of wind loadsThe wind loads are calculated from the gust velocity pressure and the coefficient of the wind pressure. The gust velocity pressure is determined from the wind load zone and the height above the terrain (location and height of the building).

For the coefficient of wind pressure, distinction must be made between the roof form, the position on the roof (zone) and the load induction area. An example of distribution according to zones is shown on the right. More exact details for the determination of the wind loads are given in DIN 1055 Part 4.

6.6.3 The purlin roof: Kalzip parallel to inner skin

The clips are fixed to the purlins or the inner skin spans parallel to the Kalzip sheet. Depending on the design of the bottom skin, an inter mediate section may be necessary with double skin roofs. The clips are normally positioned on top of each purlin.

In re-roofing projects with narrow spaced purlins it may be sufficient to position the clips on every second purlin only. With regard to an even load distribution the clips are alternately arranged on the purlins.

A design calculation is required. Please consult our local representative for design calculations.

6.6.4 Kalzip DuoPlus 100 and Kalzip Duo 100

The Kalzip DuoPlus 100 system always consists of a full layer of 10 cm thick, rigid thermal insulation, the DuoPlus rail, the DuoPlus clip and the special screws for fixing the rail onto the substructure.

In contrast to this, the Kalzip Duo 100 system does not contain a full layer of rigid thermal insulation. Strips of rigid insulation with a width of 24 cm and a thickness of 10 cm are simply inserted under the Kalzip DuoPlus 100 rails.

In the case of both systems, only the named components will be permitted. The arrange-ment of the rails and the number of connec-ting elements are outlined in the installation plan. The DuoPlus clips are secured against shifting by means of a plastic strip that is attached in the factory.

First of all the rigid thermal insulation is placed on the substructure. A full layer of rigid insulation is used in the case of Kalzip DuoPlus 100. Strips of rigid insulation are used in the Kalzip Duo 100 system and any spaces between these strips are filled with soft thermal insulation or rigid insula-tion. The DuoPlus rails are then arranged on the thermal insulation in accordance with the installation plan and are connec ted to the substructure through the thermal insulation.

The special DuoPlus clips are inserted into the rail and rotated so that they are positioned parallel to the seam direction (minimum rotation angle = 45°).

The first row of clips, at the start of the installation surface (gable end), is aligned precisely and fixed into the rail by means of a screw through the base of the clip. The remaining clips are inserted into the rail and positioned parallel to the Kalzip seam direction. Every tenth row of clips is fixed with a screw to prevent shifting.

The final row of clips, at the end of the installation surface (gable end), is also secured into the rail by means of a screw through the clip base. The compressible thermal insulation is then placed on top and pressed over the clips. The Kalzip roof structure can then be installed as normal.

The DuoPlus rail must be long enough to cover at least two ribs of the trape zoidal deck and can be secured in it. If this is not possible, then a section of adequate length can be installed next to the first row (see positioning diagram for rafter roof and purlin roof).

Positioning scheme Kalzip rafter roofThe system requires that the DuoPlus rails are positioned at an angle of 45°.

Positioning scheme Kalzip purlin roofThe system requires that the DuoPlus rails are positioned parallel to the purlins.

6.6.5 Kalzip FOAMGLAS® System

The system always consists of FOAM-GLAS® insulating slabs installed and bonded across the full surface area, the L-shaped claw plate, the composite clip with fixing elements and optional com-pressible thermal insulation.

No compressible thermal insulation is used with Kalzip AF; in this case, a PE film is used as a separating layer.

Kalzip FOAMGLAS® slabs are available in different formats and are suitable for substructures such as:• steel trapezoidal profiles• timber lining• concrete slabs

The slabs are bonded to the substructure using either a cold-bonding agent or hot bitumen and the bonding process can be carried out in an external temperature as low as +5° C. In lower temperatures the substructure should be prewarmed accor-dingly. In the case of trapezoidal profiles, bonding is carried out on the upper flanges. When the substructure is closed, the entire surface of the FOAMGLAS® and all joints are sealed with hot bitumen. The butt joints of the plates are completely sealed using the edge dipping process. A hot bi-tumen top coat seals the surface and cre-ates a prepared base for the subse quent construction work.

In order to attach the Kalzip composite clips, the newly developed, galvanized L-shaped steel claw plates are inserted under heat in a fixed grid, taking into ac-count the respective roof geometry and wind/suction load. A friction-fit, cold bridge-free connection is created with the insu-lation layer (in accordance with building approval Z-14.4-475 issued by the Institute for Building Technology).

In addition to this, a layer of bitumen with polyester fleece should also be applied above the insulation layer and claw plates. The Kalzip composite clips are installed on the claw plates using the recommended fastening elements.

Kalzip AF profiled sheets retain the possibi-lity of free movement due to a durable PE film as an isolating layer.

Design specifications

The Kalzip profiled sheets are installed in the usual manner. When Kalzip AF is used, the Kalzip backing strip should be used during welding. Only components which have been approved by the building autho-rities should be used with the FOAMGLAS® system. The arrangement of the L-shaped claw plates and fastening components (type/no.) is specified in the installation plan.

Curved roofsAll roof shapes are possible. In the case of large radii, the insulated slabs are con-nected in a polygonal manner or, in the case of smaller radii and freely shaped designs, they are delivered already in the respective shapes or cut to size at the construction site. The suppliers have a team of technical advisors who will be delighted to advise you on these roof shapes. We recommend that you seek their advice at the earliest possible stage.

The reference values for the radii (r) are:r 12 m: slabs installed in a polygonal manner (grind edges if necessary)r 6 m: half slabs installed in a polygonal mannerr 6 m: special roof shape with formed parts from factory

FOAMGLAS® is made from 100% pure glass and is therefore totally inorganic. It is manufactured from recycled glass pro-ducts and the natural mineral materials sand, dolomite and chalk in the thermal foaming process. It contains no CFCs, flame retardants or binders, does not release any emissions and does not shed any fibres.

Fire protectionFOAMGLAS® is non-combustible and when used in combination with the fixing system and the Kalzip aluminium profiled sheets contributes to wards fire protec-tion.

Fire cannot spread across the foam glass insulating layer. FOAMGLAS® insulating materials, the L-shaped claw plate and the Kalzip profiled sheets are non-combustible and as so-called “hard roofing” are resistant to flying sparks and radiating heat (“fire from the outside”).

A roof featuring a design made from FOAMGLAS® and Kalzip specified by the manufacturer, is able to meet DIN 18234-1 requirements and can therefore be used in accordance with the construction stan -dards for industrial buildings.

6.7 Connections

The Kalzip profiled sheets are connected to the substructure by clips made of ext-ruded aluminium. The clips have diverse holes in the baseplate. Special connecting elements are used, depending on the substructure.

Note: The number of connecting elements depends on the static requirements and must be determined in each case. At the edges and corners of roofs as well as at the edges of walls, the connecting elements must be dimensioned for increased wind suction loads. The anchorage depth of

the screws in wooden substructures is determined according to DIN 1052 T2. The minimum anchorage depth of the screw in the wood is 4 x ds. The maximum accountable anchorage depth is 12 x ds. (ds = nominal diameter of the screw). The connecting elements must be made of stainless steel or aluminium. The use of galvanised carbon steels is not possible.

Design specifications

6.8 Thermal expansion

Temperature changes can cause length variations and these must be taken into account. The thermal expansion coefficient of aluminium in the observed temperature range is approx 24 x 10–6/K. When the pro-filed sheets are installed at a given tempe-rature of 20°C, there will be an expansion in sheet length of approx. 1.5 mm/m in summer (+ 80°C) and a contraction in sheet length of approx. 1 mm/m in winter (-20°C).

However, as adjacent components are also subject to variations in temperature, and the substructure can usually absorb elongations, a variation in movement of ± 0.5 mm/m may be applied to the sheet length in practice. If these requirements are not fulfilled then the maximum values stated above must be assumed.

6.9 Design of fixed pointsKalzip aluminium clip / Kalzip composite clip

The fixed point prevents slippage of the profiled sheets and is the point of each Kalzip profiled sheet that is not subject to a change of length. Each Kalzip profiled sheet is to be secured at the fixed point against displacement.

Fixed points are statically verified and are to be taken from the installation plan.

A hole for the blind rivet is drilled through the small flange into the head of the clip at an angle of 45-60° degrees, the rivet is in-serted and the swage head is covered by the large flange of the next profiled sheet.

Alternatively, the fixed point is manufactu-red by the insertion of bolts through the webs of the Kalzip and the fixed point clip. Sealing washers must be inserted on both sides (bolt head and nut). If a composite clip is used for the fixed point, all drilling swarf must be removed from the profiles, since the composite clip is made of plastic-sheathed steel. Rust stains on the profiled sheets are thus avoided. For the further installation of the roof surface, the Kalzip profiled sheets are placed with the large flange on the small flange, aligned to the eaves and only then pressed into the next row of clips.

If the fixed point is not located directly at the roof ridge, then the elongation of the Kalzip profiled sheets from the fixed point to the roof ridge must be taken into account when forming the covering of the roof ridge. Each Kalzip profiled sheet may have only one fixed point. Kinks in the Kalzip profiled sheet, fixed lighting elements etc. are like-wise fixed points and must be taken into account. No second fixed point may be manufactured.

6.10 Ridge, eaves, gable ends

The standard ridge consists of three com-ponents: The ridge closure with its chamber reduces the wind pressure and at the same time fixes and protects the foam filler against UV radiation and birds. The foam filler acts as an additional “sealing” of the end of the Kalzip sheet preventing rain water from pene trating into the system. The fol-ding up is the final protection against the ingress of rain water into the ridge.

Generally the ridge is also the place whe-re the fixed point is located. If the fixed point is positioned elsewhere, then the ridge must be designed as a sliding struc-ture to be able to accom modate the ex-pansion movement of the profiled sheets. It is a fact that ventilated ridges cannot be completely sealed against snow. In case of high sealing demands or direct exposure to strong wind additional mea-sures such as the installation of wind de-flector plates or similar devices will be neccessary. At the eaves the drip angle stiffens the bottom sheet and keeps the eaves filler in position. On extremely low pitch roofs both the eaves filler and the folding down of the bottom sheet ensures that no water can flow back towards the building. The gable end is secured by the gable end hook and the gable end clamping section. (see page 13).

Design specifications

6.11 Skylights/Smoke/heat extractors

Specially designed soakers are supplied for the installation of skylights and smoke extractors, etc.For arched roofs, special curved soakers are required. The soakers can either be welded or sealed (in the case of a minimum roof pitch of 2.9°) into the roofing. Welding is the recommended option.

The steel soaker is securely connected to the substructure. The vapour barrier is in-stalled on the soaker and extends up to the height of the thermal insulation. The covering frame is either welded or sealed to the Kalzip sheets and is able to move with the Kalzip roof skin. The upper con nec-ting frame securely connects/seals the sky -light or smoke extractor in the roof skin.

Skylights and smoke extractors must not be walked on. As these must be regularly accessed for servicing and maintenance work, it is recommended that the area around the opening is reinforced with rigid thermal insulation. Large lighting elementsor rows of sky lights can require special solutions and must be planned in detail.

6.12 Transverse joints

It is not always possible to produce the required Kalzip sheet length in one element. In most cases the length of the sheets is determined by transport limitations, so that the sheets must be joined by overlapping. Especially with arched roofs the maximum loading height of the trucks must be obser-ved. Obviously, the requirements for abso-lute tightness of the overlapping joints are very high. Therefore it is necessary to take great care when making over lapping joints. Overlaps are positioned on top of the sup-port, if the joint is located at the fixed point. Otherwise the profiled sheets have to be joined directly next to the support. Joints can be either welded or sealed.

Welded jointThe Kalzip profiled sheets to be joined are overlapped by approx. 10 - 20 mm. The welding seams should be supported.

The structure underneath the welding seam must be secured against fire, e.g. by means of the Kalzip welding underlay. Welding seams must maintain a minimum distance of 100 mm to the Kalzip composite clip in order to avoid the clip being damaged by heat. If necessary, the fire brigade must be informed before carrying out welding work.

Welded connecting frame

Page 45: KALZIP Roof Technical Brochure

Kalzip 45

Sealed joints(only possible with minimum roof pitch of 2.9°) The profiled sheets are installed in a precise sequence according to the assembly in struc -tions. The critical tightness of seal is achieved by three rows of silicone in the joint zone of the individual profiled sheets plus two rows of sealing rivets. The overlap is 200 mm.

6.13 Substructures

Kalzip roofs can be installed on all kinds of substructures. With metal or timber substructures the clips are directly fixed to the substructure. With metal substructures contact corrosion must be taken into con -sideration. As, with the exception of Kalzip AF, there is no direct contact between

Kalzip and the substructure, the thermal barrier pads under the clips provide suffi-cient separation.

On concrete substructures a suitably anchored steel section or timber batten (minimum thickness 40 mm) must be inserted.

6.14 Cantilevers/clip bars

If the roof is to protrude at the eaves, addi-tional substructures are dispensable provi-ding that the clips are installed as clip bars. They are fixed to the roof with appropriate length and serve as support for the Kalzip sheets as well as a fixing for the gutter (see table of roof projections and 6.16).

6.15 Installation rules

Individual verification is required in each and every case. Roof projections are not accessible. The ends of the Kalzip sheets must be joined with an eaves angle. The length of the clip bars is outlined in the diagram opposite.

Design specifications

6.16 Roof projections without clip bars

An additional substructure can be omitted in certain conditions where the roof extends beyond the eaves. This overhang can be installed without clip bars, whereby the roof projection without clip bars and subsequent accessibility is adjusted to comply with the respective building height and material thickness (see also table). The minimum length of the Kalzip tracks is 5 m.

In this kind of design a short clip piece can be installed within the seams to secure the gutter support. The clip is attached by using either 2 rivets in the clip head or 2 screws. As there is no connection to the substructure, the Kalzip profile sheets are able to expand freely. With a sheet length of greater than 12 m the downpipe must be designed to accommodate the elonga-tion of the tracks, e.g. by means of move-able pipe laps. The sheets must be con-nected with the eaves angle in each case.

Please note:The roof projections are not accessible during installation or before the seams are zipped. Please observe and follow all ins-tructions relating to safety measures and fall arrest equipment. Roof projections should be fitted with clip bars in the case of values above 1.0 and up to 1.5 m.

The roof projection (a) is calculated from the spacing between the first clip at the roof edge and the outer edge of the Kalzip.

When the Kalzip profile sheets are visible from below, it is advisable to always use load spreading equipment when gaining access.
