General information External wall designArchitect / consultant / contractorare to assume responsibility for thecorrect design and execution of theexternal wall and its cladding - in-cluding all thermal, water, vapourand wind insulation layers - all inaccordance with good buildingpractice.

Facade engineeringThis DIM has been based uponSwiss building standards. For anyproject abroad, the structural engi-neer must verify compliance withlocal building codes, standards andregulations. Structural engineer /contractor are to assume overallresponsibility for the facade engi-neering, including• to determine material and sizes

of all sub framing members• to determine all fastening details

to sub framing and panels

Project specific orderingThe characteristics of the raw ma-terials determine properties andappearance of the SWISSPEARLpanels. Subtile visual differencesmay occur between production bat-ches. Orders should make allowancefor this by itemising quantities ac-cordingly, so that panels for adja-cent surfaces on the same job canbe supplied from the same produc-tion batch.

System Description

CharacteristicsThe SWISSPEARL SIGMA 12 sys-tem consists of large size fiber ce-ment panels, with concealed me-chanical fasteners for high endarchitectural, rear ventilated faca-des.System descriptionThe SIGMA 12 rain screen facadesystem consists out of 12 mm thickSWISSPEARL panels with a maxi-mum net size of 3040�1220 mm(10�4 feet). At the factory, the pa-nels are cut to the required size, theedges slightly chamfered and im-pregnated. Still at the factory, un-dercut holes are drilled into the rearside of the panels. On building site,the cleats are fixed to the rear sideof the panels. After installation ofthe horizontal support rails onto ver-tical sub frame, the panels are hungby the rear attached cleats into thehorizontal support rails. Subse-quently each panel is levelled outby 2 adjusting screws and a loca-ting pin is inserted to prevent thepanel from horizontal wandering.

Anchor components

1 Undercut dowel anchor

2 Stainless steel socket head screw M6�12 mm

Undercut anchorUndercut hole is drilled at thefactory at positions as per pro-ject specific requirements [1].

Insert dowel anchor. The squareshaped collar (10/10 mm) standsproud of the panel surface andcorresponds to the square cut outin the cleat to be attached [2].

By inserting the socket screw thedowel anchor expands into theundercut zone of the drill hole.Thus the anchor gets held backand anchoring effect results [3]

PlanningThe SIGMA 12 system calls for ca-reful planning of all facade compo-nents, starting at the very beginningof the project. Based thereupon, allcomponents of the facade systemcan be manufactured according toprecise requirements and can beinstalled on building site the mostefficient way.

ResponsibilityThe architect, engineer, specialconsultant, contractor - as the casemay be - assumes full responsibili-ty for the planning and execution ofthe cladding system, including de-sign and calculations of buildingphysicist and structural engineer,water and vapour management de-sign, construction details, tenderdocuments, specifications, as wellas for all measurements and di-mensioning on building and clad-ding.

Fiber cement panelsSWISSPEARL panels 12 mm forSIGMA 12 cladding systems aremanufactured as ordered accordingto list of panels. At the factory, pa-nels are cut to size, panel edgesslightly chamfered and impregna-ted; undercut holes are drilled intopanel rear side.

Other componentsAnchors, socket head screws, cle-ats, double cleats and horizontalsupport rails and pertaining rivetswill be delivered as ordered per listof components.

Panel jointsWhen needful, it must be possibleto replace a panel in mid facadearea. Therefore provide sufficientjoint width to allow sliding in andout of the panels. Minimum jointwidth is 10 mm (13/32 inch). As pa-nel joints are open, paint supportprofiles black at joints and usethermal insulation with UV resis-tant black top layer.

Ventilation cavityNet cavity thickness is minimum40 mm (1 9/16"). The thermal insula-tion layer must be well fastened tothe wall as not to obstruct the airflow within the cavity.

Ventilation opening at bottomProvide perforated screen at bottomof cavity to keep out rodents/vermin.

Sub framingSub framing consists generally outof brackets and vertical supportprofiles provided locally, and hori-zontal support rail, to be suppliedby SWISSPEARL.

Architect, engineer, special consul-tant, contractor - as the case maybe – assumes responsibility for thedesign, specification and executionof all sub frame members includingall pertaining fasteners.

Butt joints within vertical sub fra-me profiles must coincide with pa-nel joints. Vertical profile lengthgenerally from storey to storey.

CleatsCleats and double cleats are at-tached to the panel rear face onbuilding site. Both double cleats inthe top row at each panel end bearthe panel dead load and are adjus-table in height by adjustment screwin order to level out the panel. Onedouble cleat per panel shall have alocating pin. All other cleats aresingle cleats and are bearing windload only. EPDM U-sections arefitted to the cleats in order to pre-vent rattling noise from wind.

SealantNo sealant shall be used in con-junction with the SIGMA 12 clad-ding system. Where the use is una-voidable, best suitable would behybrid polymer, poly urethane oracrylic sealant, do not use silico-ne, poly sulphide or Thiokol mate-rial.

DimensioningThe sub frame and claddingconstruction is to be calculated bythe structural engineer on the pro-ject, employing FEM (finite ele-ments method) or special facadecalculation programs.

The number of anchors depends onpanel sizes, sub frame design andthe exposure to stresses; and mustbe calculated for each individualproject. Wall brackets and supportprofiles are assumed to be bend-proof.

Planning I Calculation values

Max. distances betweenanchor pointsBased upon Swiss building stan-dards, i. e. wind speed up to 140km/h or 0.9 kN/m2, (building fringezones with increase wind load), forpreliminary planning purpose thehorizontal distance between anchorsmay be determined according to thetable as follows:

m8otpu mm057 mm056

m22otpu mm057 mm045

m05otpu mm086 mm064

Horizontal rails at 750 mm centers.

For final determination of anchorquantities, the structural engineerwill take into consideration:• factor applicable wind speed• factor location in the field and

building height• factor building shape

Distance anchors to paneledgesHorizontally 70–150 mmVertically 70–150 mmRecommendation 100 mm

Distances for anchors must be cal-culated for each project individually.Maximum distance between an-chors is 750 mm.

Facade normal and fringe zoneParticularly concerning negativewind loads it is essential to diffe-rentiate between normal zone(mid field facade) and fringe zone(at building corners and on top) asshown on scheme.

The extent of the fringe zone is 1/10of the building length and height(minimum 1 m, maximum 2 m).

Storage on building siteFor storage on building site the pa-nels must be protected from humi-dity and dirt. The plastic foil co-vering the pallets serves only asprovisional protection, and is notsufficient for storage.

Protecting the panelsStore the pallets under roof. Wherethis is not possible use tarpaulin.If panels are stored longer than 2months, stack the panels betweenbattens to allow air circulation.

On site storage

Danger during transportationand installationFor transportation, handling and in-stallation all measures must be ta-ken to avoid damage to persons,material or property. All local, state,federal and other applicable safetyregulations must always be com-plied with.

Wrong: Do not drag panels from stack Correct: Always lift panel off the stack

AccessoriesUse only SWISSPEARL SIGMA 12accessories, do not use any materialsupplied by others.

Fabricating SWISSPEARLpanels• Use power tools with dust

extraction• Avoid the use of tools which

produce fine dust• Always work out of the weather• To cut panel use circular saw

have been delivered to site• Sub frames are to be designed bystructural engineer/contractor. Ther-mal expansion/retraction is to beaccounted for by providing fixed/expansion point brackets• Expansion joints within supportprofiles must coincide with paneljoints

• Uninterrupted air circulation, frombottom to top, must be maintainedbehind Swisspearl facade panels• Do not install Swisspearl facadepanels/systems directly onto wallsurfaces of any kind• Do not use any sealant in con-nection with Swisspearl facade pa-nels

Storage and Handling• For off loading lift long palletsfrom short side, using fork extensi-ons. Otherwise lift from pallet longside, setting forks apart to preventpallet from bending.• When lifting pallet up by crane,attach pallet at sufficient supportpoints to prevent it from bending• Stacked Swisspearl panels to bestored under roof. If not possible (e.g. on building site) use tarpaulin tocover the pallets (the plastic shee-ting the pallets are wrapped in, isnot sufficient)

• Pallets/stacks always to beplaced horizontally, and to be keptoff the grade• Never slide panels across oneanother. Lift panels individually toavoid scratching• Panel stacks to be max. 500 mm (2’)high, do not stack more than 2 pallets.When re-stacking panels, insert foamfoil between each panel to protect thesurface. Protect stack adequately• All manufacturer’s labels, in-structions, DesignInstallationManuals must be made available tothe entire staff on building site.When re-stacking/re-palletising,the instructions must be attachedonto the new stacks/pallets such asto be noticed easily

Fabrication and Handling• Fabricate Swisspearl facade panelswith vacuum equipped power tools• Fabricate Swisspearl facade pa-nels with tools recommended bymanufacturer• Immediately remove fabricatingdust from panel• Never use sawing system withwater cooled blade

• After saw cutting, each paneledge must be sealed by usingLUKO impregnation liquid• Do not allow LUKO impregnationliquid to flow onto the panel face• Install Swisspearl facade panels/systems by contractors trained &instructed by Swisspearl/distributor• Make sure that dust is removedfrom face and back side of panelprior to it’s installation• If a panel is to be rested on it’sedge, use protection pads to avoiddamage

Cleaning• Do not clean Swisspearl facadepanels by dry methods• Immediately remove cement tainsby applying a solution of 10% aceticacid in water, allow to react 5-20 mi-nutes, but do not allow to dry out.Follow up with a cold, clean waterrinse. If required, use high pressurewater blaster at 40-80 bars (580-160psi), always test this methodon in-conspicuous panel area• Never clean a facade in thebright sun light
