SpeedDeck® is the original secret fix profile and has a tremendous track record.

In the 40 years since its inception, SpeedDeck® has been used in Australia, the

Far East, mainland Europe and in the UK where many millions of square metres

have been installed since 1979.

In all of this time, and through enormous and profound changes in regulations

and the expectations from roofing systems, SpeedDeck® has maintained the

Product Information - On-site Rolling

On-site Rolling

Production on-site involves the full-size

SpeedDeck mobile rolling mills mounted in

self-sufficient lifting platform containers.

The factory essentially moves to site

for the manufacture of the SpeedDeck

profile and requires minimal production

involvement from the roofing contractor.

The production unit is fully mobile and any

length of profile can be manufactured on-site

at ground level, on a tower or direct to the

roof suspended by crane. The SpeedDeck®

on-site manufacturing process involves a

minimum of input from the installer with

SpeedDeck Building Systems Ltd providing

production personnel, method statements,

safety and training certification, lifting beam

and slings etc.

The manufacturing process is carried

out by SpeedDeck factory personnel, in

controlled conditions and to identical QC

and ISO9001 procedures as in the factory.

Detailed method statements and risk

assessments covering the manufacturing

process, safety, training certificates,

hoisting and roofing contractor

requirements etc are available on request.

Further information on the implications

of on-site manufacture such as space

requirements, personnel needs, etc. are

available from SpeedDeck along with site

visits by production personnel to establish

the feasibility of on-site manufacture

to a particular project. SpeedDeck will

advise on the optimum method of on-

site manufacture with the choice being

to produce at ground level, suspended

by crane at eaves level, from an inclined

structure or up a slope, or on a secure

platform directly at eaves level.

Product Information - Curves

[email protected]

Curves

The versatility of SpeedDeck and its simple installation

method enables it to be cost-effectively curved to

suit most designs. Curved SpeedDeck is installed in

the same manner as straight SpeedDeck and can

create a roof with no exposed fixings or penetrations.

The various methods and parameters of curving

SpeedDeck are described in this section. Lifting beams

and slings are provided with natural and smooth-

curved SpeedDeck to assist in hoisting onto the roof.

For further information on the use of curved

SpeedDeck refer to the installation section.

Natural convex curves

minimum radius (convex)

55m* - 0.6 - 0.7mm steel SpeedDeck

55m* - 0.9mm aluminium SpeedDeck

40m - StramLiner/WalkLiner

[*50m minimum radius, risk of non detrimental oil canning

from 55-50m radius]

SpeedDeck is manufactured flat and curves to the

curvature of the structure as it is lowered onto the

roof in bundles. A double clip arrangement is needed

for curved roofs under 90m radius, see diagram.

The minimum radii are set by aesthetic standards

and tighter radii can be achieved by low additional

cost pre-curving, to avoid potential ‘oil canning’ etc.

Design using the load/span charts from

performance section.

A suggested maximum span of 1.5m is advised for

all materials to facilitate the optimum curvature.

MultiVault and shallow CurveLight GRP rooflights

are suitable for use in natural-curve roofs.

Purlins must be radial to the curve. If facetted

rafters and extended cleats are used, tolerances

on cleat angles can result in surface marking

(generally not detrimental to performance) this

can apply to natural or smooth curved SpeedDeck.

Install SDS20 screws through the male rib into the

clip at the two/three apex purlins as a fixed point.

These will be covered by the overlapping female rib.

StramLiner/WalkLiner will naturally curve to these radii.

There is no length limit to this form of curve.

Natural concave curves

minimum radius (concave)

25m - 0.9mm aluminium SpeedDeck

Natural concave curves are currently available in

0.9mm aluminium to a minimum radius of 25m.

For other materials and specific design input for

concave curves, please contact the SpeedDeck

Technical Department. In general, 1.2m maximum

spans and 80% of design capacity should be used,

along with a minimum sheet length of 6m, with

the end spans straight and tangential. WalkLiner

may need to be pre-curved to match concave

SpeedDeck, subject to material and radius.

SpeedDeck is smooth-curved as a low additional

cost secondary operation to the original roll

forming. The process forms a smooth curve with

no crimping or additional swages and does not

induce stresses leading to oil canning.

Note that the ‘hockey stick’ sheets for waveform

roofs are handed.

SpeedDeck sheet lengths are only limited by

transport, subject to radius, sheet length and rise

above the chord. StramLiner/WalkLiner sheet lengths

are generally shorter and not limited by radius.

The normal maximum spans and load/span

capacities apply to smooth curves.

WalkLiner in steel is smooth-curved by a similar

process and to suit the SpeedDeck curvature. This

gives a smooth and clean internal appearance.

Rooflights are best restricted to running along the

apex in barrel form, supported on upstand kerbs.

At radii over 20m shallow CurveLight can be used.

Crimp-concvex curves

minimum radius (SpeedDeck, convex only) 450mm

no maximum radius

max sheet length 8.8m

Constant or varying radii are possible

StramLiner/WalkLiner can be concave and

convex crimp-curved

SpeedDeck is crimp-curved as a secondary

operation to the original roll forming. The process

consists of regularly placed and controlled mini-

ribs across the width of the pan with mini-rib

spacing and depth governing the radius. For larger

radii, the crimps are very shallow and not readily

noticeable. Sheet lengths are limited to 8.8m,

due to sheet handling restrictions in the factory

during the crimping process.

StramLiner/WalkLiner in all standard materials

can be curved by the same process.

The special eaves detailing is not required with

crimp-curve sheets. However, clip positions should

not coincide with the crimps.

The normal maximum spans and load/span

capabilities apply to crimp-curves.

Curved eaves can be created using SpeedDeck

and StramLiner/WalkLiner. The minimum radius

is 450mm; this is the external radius of the

inner sheet. Clearly, if StramLiner/WalkLiner is

employed at a 450mm radius then the SpeedDeck

radius will be greater.

r = 450mm minimum external radius

L = overall length (8.8m max.)

a = 200mm minimum

k = included angle

NOTE: that SpeedDeck sheets can only be laid in one

direction and that the orientation of the sheet must be

specified when ordering. The dimension ‘a’ should be kept as

small as feasible to ease installation.

When crimp-curved SpeedDeck forms a part of

a wall sheet, with a maximum length of 8.8m, a

step or secret gutter should be designed between

the curved eaves and roof sheet. Longer sheet

lengths can be used in this situation if an ‘in-to-

out’ flashing is used between the curved eaves

and vertical cladding.

If the crimp-curved sheet involves a straight

section, the handing of the sheet will need to

be specified at order. SpeedDeck provides an

ordering form to reduce the risk of errors.

Please refer to SpeedDeck for information

required for ordering and using crimp curved

SpeedDeck and StramLiner/WalkLiner.

Waveform roofs

Waveform SpeedDeck roofs combine the features

of convex and concave SpeedDeck. The basic

design criteria are very similar and assistance

should be sought from the SpeedDeck Technical

Department. Part-curved SpeedDeck sheets allow

a smooth-curved convex area to be used with

a natural-curved concave area, as illustrated

below. The minimum radii for 0.9mm aluminium

SpeedDeck are 15m convex (pre-curved) leading

into 25m concave (formed naturally on-site).

Note that sheets are handed.


Waveformroof

Bow-overroof–NorvicHouse,Norwich Curvedon-planroof

Bow-Over roofs

An eaves-to-eaves bow-over design can minimise the number of interruptions in a roof and, in so doing, speed

installation and reduce cost. SpeedDeck sheets are made in one length from eaves-to-eaves with no ridge

treatment required. The roof consists of two uniform slopes generally at 1-2° with a radiused central section at

the apex. Bow-over roofs are best formed in 0.6mm steel SpeedDeck and 0.9mm aluminium SpeedDeck. Install

SDS20 screws through male rib into clip at the two purlins each side of the apex, as a fixed point. These will be

covered by the overlapping female rib.

L = SpeedDeck span

established relative to

wind loads.

S = at least 2 bays (3

purlins) down slope on each

side of the bow, to be in a

straight plane.

R = purlin positioned at

ridge line to support sheet,

in case of foot traffic

causing deformation. Particularly useful for aluminium. The curved ridge effectively becomes the fixed point.

Penetrations

Openings can be weathered using in-situ welding

for aluminium SpeedDeck or GRP in-situ bonded

soakers. Curved roof constructions are generally

not appropriate where the roof has openings

involving apron flashings, because these normally

terminate at the ridge flashing.

Pipe penetrations can be weathered using the

‘Dektite’ form of soaker or by in-situ welding in

aluminium SpeedDeck. Typical welded soaker

details are shown in the typical construction

details section.

Flashings

The verge flashing is often the most noticeable

item on a curved roof and hence deserves special

attention in design, fabrication and installation.

Faceted flashings are commonly used on very

large radii. For tighter radii of 60m or less

pre-curved flashings are advisable; the tighter

the radius the greater the need for pre-curved

flashings.

Welded, dressed and post-painted 2.0mm or

thicker aluminium flashings potentially give the

best appearance.

Pre-painted steel and aluminium can be curved

using the lockform process in which the curved

junctions are welted together.

Natural aluminium flashings can give a poor

appearance and consideration should be given

to a solid light grey colour for flashings with a

stucco-embossed SpeedDeck roof, and increased

material gauge.

Accessories

SpeedDeckclip

The SpeedDeck clip anchors every rib to every

spacer position. It engages with the SpeedDeck

rib providing the strength of attachment and

accommodating thermal movement.

Galvanised steel clips are suitable for the majority

of applications with both steel and aluminium

SpeedDeck. Where the clip-to-sheet connection

is likely to be wetted or in an aggressive

environment (single-skin canopy, single-skin

projecting eaves etc) additional protection can be

provided by using epoxy powder-coated clips and

starter clips with stainless steel screws.

For fixing to steel, the two central screw holes

should be used. When fixing to timber, four screws

per clip should be installed through the four outer

holes. Screws to suit the clip are supplied only by

SpeedDeck, standard hex-head screws must not

be used with SpeedDeck clips. If SpeedDeck sheets

are removed and then replaced, the SpeedDeck

clips must also be replaced.

Halfclips

Half clips are used to complete a roofing area i.e. at

gables, rooflights and valleys. Half clips are formed

on-site from a SpeedDeck clip cut in half, diagonally

for ease, across the narrow base of the clip.

Two screws should be used in half clips to prevent

rotation. At rooflights or at other positions, the

half clips can be turned through 180° so that

they point back into the construction and do not

protrude into and under the rooflight.

Pre-AssembledstarterClips

The starter clip is used as an adaptor to provide

a false male rib to one side of the full SpeedDeck

clip. It engages with the first female rib at the

commencement of each fixing sequence and

when re-commencing after forming openings.

The starter clip is factory pre-assembled onto the

SpeedDeck Clip.

The starter clip must be used whenever a clip has

to be engaged into the female rib.

Fillerblocks

25mm polyethylene SpeedDeck vented filler

blocks are provided in 1020mm long pairs for use

at the eaves and at the ridge. For valleys and hips

raking cut fillers are available.

50mm polyethylene StramLiner/ Walk-Liner solid

under profile air-seal filler blocks are provided for

sealing Stramliner/ WalkLiner at eaves and ridges.

For valleys and hips these are provided angle cut

to suit the rake.

50mm StramLiner/WalkLiner fillers are essential

to avoid draughts, air leakage and hence energy

loss. They should be positioned at the outermost

junction to prevent air movement to or from the

outside or from inside the building to within the

roof construction.

Wherever possible the 50mm air-seal under-liner

filler should be secured with the liner fixings with

at least 2 screws per pan.




IsoBar

IsoBar is an engineered bracket and rail spacer

system designed to reduce cold-bridging across

the insulation and provide a strong support . IsoBar

consists of a roll formed, high-tensile steel profiled

angle rail with joggle joints and steel support

brackets. The brackets are available in a range

of depths, slotting into and engaging within the

rail and have an integral sealer pad. The bracket

spacing, reduced metal-to-metal contact and

integral sealer pad result in minimal cold-bridging.

‘U’ values for SpeedDeck constructions and IsoBar

bracket centres relative to spans and loads are in

the performance - thermal section. IsoBar is an

integral part of SpeedDeck Agrément constructions.

The maximum IsoBar bracket centres are 1020mm

(one per StramLiner/WalkLiner width) and two

fixings per bracket should always be used.

Isobar

Length: 3060mm net cover

Other lengths available to order.

Depth (h): 60 - 250mm in 10mm increments

Width: 40mm

Thickness: Rail 1.25mm

Bracket 1.5mm

Weight: 1kg/m nominal

Material: Rail 275gsm galvanised steel

350N/mm2 yield

Bracket: 275gsm galvanised steel

The maximum cantilever beyond the last bracket

is 300mm. A bracket should always be located

within about 100mm of the joggle joint. Brackets

at the ridge (fixed point) purlin should be

positioned at 765mm centres.

When used in an acoustic construction

(SoundRoof or other) using top hat stools

under the brackets, the maximum bracket

centres should be 765mm nominal (every third

StramLiner/WalkLiner pan).

At the eaves of curved roofs where a double clip

arrangement is used, set brackets at 510mm centres.

Vapourcontrollayers

The primary vapour control layer within SpeedDeck

constructions is formed by sealed StramLiner/

WalkLiner, which can be backed-up by the optional

additional use of StramCheck. Unperforated

StramLiner/WalkLiner laps are always sealed.

Note that StramCheck is not optional in

constructions using perforated liner. There is no need

to seal the laps of the liner in this configuration.

Extra care is needed in design and installation

with perforated liners to achieve an air seal and

vapour seal at penetrations and perimeters.

If a membrane VCL layer is used and pulled taut,

increase the IsoBar bracket depth by 30mm to

give the insulation full depth.

SDSeal

StramLiner/WalkLiner with sealed laps and sealed

at perimeters is the primary vapour control layer.

SD Seal consists of robust, tear-resistant film with

a 1.0mm x 50mm butyl adhesive. SD Seal creates

an excellent seal that is robust and resistant to

damage. The plastic foil is tough and elastic and

very resistant to damage during installation.

Although SD Seal is tolerant of site conditions and

low temperatures, it should be applied to surfaces

that have been wiped clear of moisture or dust. SD

Seal should be wiped or rolled to get the best bond.

End laps are sealed using a 5x6mm diameter butyl

sealant strip within the lap.

SDSeal

Width: 50mm

Roll length: 35m

Adhesive: 1.0 x 50mm butyl

Facing : 50mm laminated film

StramCheck

StramCheck is a 2m wide reinforced 250gsm

polythene membrane for use as a vapour control

layer in a double-skin construction.

StramCheck is produced from 100% virgin

resin which is UV-stabilised and includes anti-

oxidant agents. This provides resistance to

photodegradation by UV of up to two years’

exposure and good protection against loss of

flexibility with temperature and time. StramCheck

retains its flexibility in a double-skin roof for over

20 years.

The StramCheck lap adhesive is a 1.5x20mm

butyl strip. Use a single strip in most

circumstances, applying the strip to a dry, dust

free surface. Apply a pressure to the strip to help

a bond to form.

StramCheckAL is an aluminium reinforced

polyethlene VCL for high humidity applications. Use

twin lines of adhesive strip for StramCheckAL..

StramCheck

Composition: Clear two-layer UV

stabilised polyethylene with

polypropylene reinforcement.

Size: 2m x 50m roll

SD100Breathermembrane

SpeedDeck constructions are designed to breathe

and the SD100 breather membrane is an optional

component in the roof construction.

SD100 helps to keep insulation dry during

construction, particularly at ridges or hips where

the flashing may not be installed immediately

leaving the breather exposed.

SD100 enables any moisture that should manage

to bypass the well sealed StramLiner/WalkLiner to

breathe out without affecting the insulation.

at 20°C, or 56 days’ heat ageing at 60°C, or after 100 hours’

UV ageing.




Tophatspacerstools

The 2mm galvanised steel 31mm deep top hat

spacer stool is used in roof constructions involving

pan-perforated WalkLiner and acoustic batts. The

stools are positioned under IsoBar brackets in the

pans of StramLiner/WalkLiner panels at 765mm

nominal maximum centres. The StramCheck vapour

control layer is sandwiched between the top hat

spacer stool and IsoBar bracket.

The top hat spacer creates a 31mm space for the

acoustic batts to fill.

The top hat spacers are in extruded 3mm aluminium

in high-humidity buildings

The top hat stools are always fixed using two hex-

head 5.5mm diameter screws with bonded washers

if appropriate.

Acousticbatts

These are 31mm thick 60kg/m3 rockfibre insulation

batts with integral black tissue facings to one side.

They are positioned within the perforated liner, the

acoustic batts providing excellent sound absorption.

The black tissue facing helps to avoid the ends of

batts from showing through the perforations as

shadows. The batts should always be installed with

tissue face down and ends butted together well.

Stick pins can be used if necessary over purlin

positions on steeper slopes to prevent slippage,

though they must not snag the StramCheck layer.

Adaptorbracket

The adaptor bracket is a universal device which

allows accessories to be secured to the roof

without penetrating the SpeedDeck roof sheet -

lightning conductors, walkways etc.

The basic adaptor consists of two pressings to fit

either side of the rib, two square washers to go

one either side and an M6 bolt plus Nyloc nut. All

components are 3 series stainless steel.

Two angle brackets are available as standard to

suit any combination that the customer desires.

These fittings are positioned between the square

washer and pressing.

The adaptor bracket should be fitted to the

interlocking rib and can safely withstand a 100kg

pull-off load.

Snowguard

An aluminium castellated snow guard is available

to prevent slippage of snow build-up on a roof

while allowing clear drainage of rain water. The

castellated shape prevents ice slippage under

the snow guard. The snow guard is secured to

SpeedDeck using the stainless steel adaptor

brackets without penetrating the roof surface.

SpeedDeckclipscrews

Enquire with SpeedDeck for applications not

shown in the table.

Sockets and drive bits to suit the screws are

available from SpeedDeck. 5.5mm diameter

screws plus 15mm diameter washers are

used to fix Walkliner and are tested to

ACR[M]001:2000. Note that shallow hex

heads require a modified 8mm magnetic hex

drive bit, available only from SpeedDeck.

Slottedzed

The 30mm deep slotted zed has slots in its web.

It is produced from 1.5mm galvanised steel (with

powder coated option) and is intended to provide

a ventilation zone in high-humidity application

roofs. The slotted zed is fixed at 500mm centres

via 10mm packers using 304 stainless steel screws

and is located between the breather membrane

and SpeedDeck sheet. The slotted zed requires

the inclusion of vented perimeter flashings (ridge/

eaves) for effectiveness.

SpeedDeck Designer�

SpeedDeck Designer4 interactive

software is a tool to allow the designer

to assess the critical factors in a

SpeedDeck roof design and obtain

an NBS-style draft specification

quickly and easily. It enables the

user to choose or input items

such as materials, spans and

loads. SpeedDeck Designer4 then

indicates the percentage of the

SpeedDeck structural performance

capacity used and various other

items such as ‘U’ value, weight,

condensation risk etc.

SpeedDeck Designer4 then prints

a summary of information input, the

performance criteria established and an NBS-

Structural

The published load/span data was derived by the

British Board of Agrément following full-scale

vacuum-rig, static and cyclic load tests on every

material. The static tests allowed characteristic

values to be established which were then

factored in accordance with BS5427 : 1996 to

give design values.

The design values are then proved by cyclic

testing to simulate fatigue.

The cyclic testing fluctuates the loading over

thousands of cycles to represent in-service

load conditions. Aluminium SpeedDeck was

fatigue tested to simulate 50 years of service

after which the residual factor of safety had

increased to beyond 2.5. This indicates that the

strength had actually increased over time rather

than decreased and gives great confidence in

SpeedDeck and its clips.

SpeedDeck also provides gauging templates to

assist the installer to achieve the correct profile

gauging and, hence, optimum in-situ strength.

Checking for complete rib attachment is simple

and achieved by viewing across the rib in the

direction of lay. Ribs not fully interlocked are

apparent to the eye. Refer to the installation

section for further guidance.

The derivation of wind loads for a roof covering

is a specialised activity. The roof loadings should

be provided by the structural engineer, who

should also verify that roof covering calculations

have been carried out and ideally check the

calculations for validity. The specifier should

consider including this within the contract and his

roof specification.

stainless steel fixings.

��



Non-fragility

SpeedDeck is one of the few standing seam

systems that can accept foot traffic on the

ribs. This results in a superior post-installation

appearance. The profile has above average

resistance to in-service foot traffic, be this

maintenance or unauthorised foot traffic through

vandalism or trespass.

Walking on the ribs is preferred to reduce the risk

of marking the profile. Areas of regular or heavy

foot traffic should be protected by boarding to

avoid damage particularly to the coating. Items of

plant requiring regular access should be served

by a walkway connected to SpeedDeck using the

adaptor clamps.

0.65 / 0.7mm steel WalkLiner, in multi-span

and when properly fixed is walkable at up to

1.8m spans. WalkLiner allows faster and safer

installation and very rapid initial weatherproofing; a

boon to the programme, installer, main contractor

and client.

To class as non-fragile to ACR[M]:2000. The

WalkLiner end laps must be minimum 60mm and

the profile fixed in every pan using 5.5mm hex

head screws plus 15mm diameter bonded washers.

SpeedDeck in 0.6mm steel, 0.7mm steel and

0.9mm Aluminium and Walkliner 0.65 / 0.7mm

steel are non-fragile class B. For other materials

refer to SpeedDeck.

Lateral restraint

StramLiner in 0.4mm or thicker steel provides

lateral restraint to the top flange of a purlin

by tie-action, if secured using 5.5mm diameter

screws in every pan.

Pan-perforated WalkLiner in steel will give lateral

restraint if secured by the top hats, or by 5.5mm

screws, positioned immediately adjacent to the

solid ribs.

Pan-perforated StramLiner in 0.9mm aluminium

will give lateral restraint

if secured by top hats or

screws immediately adjacent

to the solid ribs.

SpeedDeck alone does not

provide lateral restraint and

other methods of restraint

must be incorporated in the

structure.

Stressed-skin or diaphragm

action is possible with

the SpeedDeck range

of structural decks and

structural liner tray profiles.

Further information is

available from the SpeedDeck

Technical Department.

The maximum bracket centres are 1020mm nominal,

with 765mm as the maximum when top hat spacer

stools support the IsoBar (i.e. SoundRoof etc). 1020

and 765 are multiples of the StramLiner/WalkLiner

profile pitch of 255mm. Bracket centres should be

reduced to 765mm centres at ridges (for the fixed

point) and for spacers over 250mm total depth.

The IsoBar brackets at curved roof eaves using the

double clip arrangement should be 510mm.

Anti-sway brackets should be used with IsoBar,

at each end of a line and at 30m maximum

intervals between.

IsoBar rails can cantilever 300mm beyond the end

bracket, but a bracket should be positioned within

100mm of the joggle joint.

Two screws per IsoBar bracket must always be used.

Thermal expansion

The effects of thermal expansion are

accommodated within SpeedDeck by the clip-

fixing method of attachment and by the inherent

flexibility of the profile.

SpeedDeck originated in Australia over 30 years

ago, where the simplicity of the design was

evolved to deal with aspects such as thermal

expansion in the Australian climate.

Since SpeedDeck’s introduction to the UK in

the late 1970’s, the maximum lengths of sheet

manufactured have grown to exceed 100m in

0.9mm aluminium. The introduction of the on-site

rolling facility in 1996 had the greatest impact upon

this increase.

To avoid creep, SpeedDeck incorporates a fixed-point

anchorage, usually located at the ridge or apex and, in

the case of a pan fixing, concealed under the ridge cap.

For very long sheets in single slopes, i.e. over

40m, the fixed-point should be to three mid-slope

purlins, with expansion allowed at the eaves

and at the ridge. This requires fixing the ridge

independently of the SpeedDeck profile.

Curved roofs are effectively long sheets with a

fixed-point at the apex, giving no restriction on

sheet lengths. The fixed-point should be through

the male rib into the clip, concealed by the

overlap and installed at the three apex purlins.

On aluminium roofs, in-situ welded soakers should

be able to move if expansion occurs.

Verge flashings must be supported on verge zeds and

not secured to the SpeedDeck. The verge zed should

be fixed directly to the IsoBar spacer and not through

the SpeedDeck sheet. This allows independent

movement between SpeedDeck and flashings.

Aluminium flashings require movement to be

allowed at joints.


Fire• Rock-fibre and glass-fibre insulations

used with SpeedDeck constructions are

non-combustible to BS476: part 4: 1970

(1984) without any modification, special

treatments or need for bespoke specification.

• SpeedDeck sheets in all materials and finishes

have an AA classification in accordance with

BS476: part 3: 1958.

• SpeedDeck and StramLiner/WalkLiner

are Class O in accordance with the

Building Regulations, BS476 pt 6: 1989

and BS476 pt 7: 1987.

• SpeedDeck double-skin constructions

are insurer friendly.

• SpeedDeck has LPCB approval under

certificate 738a/01.

These performances mean that SpeedDeck

constructions present a very low fire risk.

They add little to the fire load and do not present

a risk from toxic fumes in fire, or from flaming

droplets endangering firefighters.

GRP rooflights, unless specified otherwise, are

SAB/3 externally and SAA/1 internally. GRP is

thermosetting and does not drip in fire situations.

GRP tends to char but not melt or run. Class O

GRP is available for internal skins.

LPCB approval ��a/0�

SpeedDeck Building Systems has invested in the

successful testing of its roofing products to LPCB

LPS1181-1. SpeedDeck has approval under LPCB

certificate 738a/01 to grade EXT-B.

The testing arose from customer requests and

demonstrates the continuing development of

SpeedDeck roofing systems to meet customer and

market demands.

LPCB approval gives specifiers and building

owners assurance that the complete systems

have been tested, which should lead to better

insurance premiums and complete peace of mind.

WhatisLPCBapproval?

LPCB approval is independent third party

confirmation that products and systems meet and

continue to meet appropriate standards. It is different

from a test, as approval helps ensure, through regular

audits, that the product continues to comply with the

prevailing standards, which are themselves, subject

to revision and up-issue. The auditing process also

helps to confirm that the product available on the

marketplace is exactly the same as the product which

was originally tested and approved.

LPCBapprovedsystem

The approved system consist of:-

• SpeedDeck® (0.6 and 0.7mm steel with 200

micron PVC coating, 0.9mm aluminium with

plain stucco, pvdf or ARS coating)

• 180 to 220mm Knauf Factoryclad glass quilt

Junction of compartment wall with roof

In situations where SpeedDeck passes over party

or compartment walls, the detail can be adopted

to meet the spirit of the Building Regulations

Approved Document B3 Section 8 paragraph 8.24.

SpeedDeck roof coverings meet a designation of

AA to BS476: Part 3: 1958.

Rockwool Insulation is classed as non-combustible

to BS476: Part 4: 1970.

StramLiner/WalkLiner liner panels meet the

designation of Class 1 to BS476: Part 7: 1971 and

Class ‘O’ in the Building Regulations.

The detail consists of filling the roof void with

compressed Rockwool quilt for a distance of

1.5m either side of the wall. The gap between the

underside of the liner and top of the wall should

be filled with Rockwool or similar fire stop blocks,

shaped where necessary to the liner profile. The

fire stop blocks should be secured in position

using angle trims.

The side-laps of the liner should be stitched at

300mm centres, using steel rivets or stitcher screws.

Thermal insulation

The building regulations AD L2 and BS EN

10211-2 have substantially changed the method

of calculation for ‘U’ values. These must now

take into account any thermal bridges within

the construction and are affected by insulation

thickness and type, spacer type, spans, profile

shape etc.

The ‘U’ values in the table provide values for

SpeedDeck constructions taking all of the above

into account.

Performance - Acoustics

Acoustics - Sound insulation and sound absorption

SpeedDeck constructions are very good barriers

to sound and highly efficient absorbers of sound

energy. SpeedDeck roofs have been successfully

used on cinemas, schools, under major airport

flight paths and to combat rain/hail noise. The

SpeedDeck Agrément double-skin construction,

for example, provides sound insulation of Rw =

45.7dB for 0.6mm steel SpeedDeck and 42.5dB

for aluminium SpeedDeck.

The performance of SpeedDeck constructions

can be further increased depending upon the

insulation and other materials used. Typical tested

values assessed by Sound Research Laboratories

are 48dB, using 0.7mm steel SpeedDeck and

WalkLiner and 49dB using 0.9mm aluminium

SpeedDeck and 1.25mm steel liner, in practical and

simple build-ups using no layers of plasterboard

and other boards. The low frequency responses in

these constructions are also very good.

The control of echo or reverberation within a

building is provided by choosing perforated steel

WalkLiner with acoustic batts and a StramCheck

vapour control layer. This assembly provides

excellent absorption and is very effective in

sports halls etc.

Perforated liner is however transparent to

sound and, while providing good absorption

characteristics, reduces the Sound Reduction

Index (SRI). The SoundRoof constructions provide

a combination of excellent sound absorption along

with good sound insulation. The constructions

were assessed by the British Board of Agrément

and are a part of SpeedDeck Agrément certificate

No. 96/3262.

48dBconstruction

Sound reduction/insulation

Sound reduction or sound insulation refers to

the reduction of sound energy passing through

a dividing element, also commonly referred to

as break-in or break-out. The principal factors

affecting the ability of an element to prevent sound

from passing through it are mass, shape, size and

the absorbent qualities of constituent materials.

The SpeedDeck Agrément certificate U=0.25W/

m2K construction provides Rw = 45.7dB with

0.6mm steel SpeedDeck and 42.5dB with

aluminium SpeedDeck (Rw being a weighted

average sound reduction value over a frequency

range of 125 - 4000 Hz). Rw of 45.7dB and

42.5dB compare very well by a factor of 8 with

the typical value of Rw=26-27dB, achieved by

foam composite panels.

A wide range of constructions are possible

with SpeedDeck, combining different insulation

thicknesses, densities and types of liner. A

range of sound reduction values are provided

in the table either from test data or calculated

on SpeedDeck’s Computer Acoustic Modelling

Facility, developed by Salford University.

The computer modelling facility allows SpeedDeck

to assess the potential performance of a double-

skin construction and to tailor it to the client’s

needs. Experience has shown the computer

assessed performance to be accurate when

verified by testing for a project.

Test data is to BS EN ISO/140/3 : 1995 and is

the most reliable guide to performance. The

components used within the tests (i.e. liner

profile/spacer etc.) cannot be substituted for

others and the test results cannot be assumed to

apply to other roof profiles without risking a loss

in performance. Because of the potential number

of combinations of materials and components and

the large number of tested constructions, it is

not possible to provide an exhaustive list in the

table. Please contact SpeedDeck for assistance

with other constructions. Acoustic performance

assessed for SpeedDeck Agrément certificate

96/3262 is indicated in the table.

To achieve the full potential sound insulation,

the construction (insulation plus membranes)

must continue over roof features such as ridges

and valleys with minimal interruption. Any

penetrations will affect performance, particularly

lightweight rooflights!

Sound absorption

Sound absorption is the control of reverberation

within an enclosed space. This is achieved

domestically by floor coverings, curtains and

furniture. On a larger scale, SpeedDeck with

pan-perforated WalkLiner or perforated deck

with acoustic batts provides excellent sound

absorption.

The absorption performances of WalkLiner and

deck were tested by Sound Research Laboratories

(SRL) to BS3638:1987/ ISO354:1985.

The sound absorption performance is independent

of the insulation layer above the StramCheck

vapour control layer and applies to all

constructions using perforated WalkLiner and

acoustic batts.

The perforated liner and acoustic batt

construction uses IsoBar supported by its

brackets at 765mm nominal maximum centres,

IsoBar is carried in turn by galvanised steel top

hat spacers. The StramCheck vapour control layer

is transparent, allowing the top hats to be seen

for fixing. The acoustic batts are faced with black

tissue, minimising visible butt joints.

SoundRoof (SRST/AL� and SRST/AL�)

The SoundRoof constructions assessed by the

BBA for SpeedDeck Agrément certificate 96/3262

combine a good sound absorption and sound

reduction performance. The perforated WalkLiner

is effectively transparent to sound transmission

and this affects the overall sound reduction Rw

value. This is compensated for by using more

dense 33kg/m3 semi-rigid rock-fibre for the main

insulation. The SRST/AL2 construction also

includes an additional 50mm of 140kg/m3 insulation

to boost the sound insulation value achieved.

The 33 to 42dB values achieved by SoundRoof

constructions do not compare well with the 45.7dB

achieved by the Agrément double-skin U=0.25W/

m2K construction - until the sound absorption

capacity also provided is appreciated and taken into

consideration. The SoundRoof constructions give a

good combined performance in terms of both sound

insulation and sound absorption.

In roof systems with perforated inner profiles

(WalkLiner/ StramLiner/ structural decks)

it is essential that the reinforced polythene

StramCheck vapour control layer is good, any

tears repaired, sealed at perimeters, sealed at

penetrations, continuous over hips and valleys,

and robustly connected to the wall air barrier. The

StramCheck layer is the roof air barrier and so

subject to the air pressure testing.

Also, be aware that the perforated liner or deck

will allow air/ sound/ smoke to travel over the top

of a wall abutting the soffit of the profile. Suitable

measures should be taken at design and installation

stage, both within the roof construction and under

to avoid air/ sound/ smoke flanking the wall.

Performance - Moisture/Airtightness

Condensation

The performance of SpeedDeck constructions

under various environmental conditions can be

checked using the SpeedDeck Designer4 software.

SpeedDeck roofs are designed to be breatheable,

airtight and watertight constructions in the same

way that human skin is breatheable but watertight.

Vapour control

The vapour control layer is formed by

StramLiner/WalkLiner with side laps sealed

using 50mm SD Seal tape. End laps are sealed

using 6x5mm butyl seal within the end laps. This

method is weather tolerant and damage resistant.

StramLiner/WalkLiner is secured to purlins with

5.5mm diameter screws with 15mm diameter

bonded rubber washers and by IsoBar brackets

with integral sealer pads.

StramLiner/WalkLiner is sealed at perimeters by

sealing and stitching to verge angle trims and by use

of 50mm air-seal filler blocks at eaves/ridge/hip/

valleys. Two fixings per pan are used to compress

the 50mm filler and achieve a good air-seal.

On roofs that have many interruptions, such as

rooflights hips and valleys, StramCheck is an

optional additional item to back up the sealing of

the liner. In these instances, it is easier to install

StramCheck and maintain an effective seal.

Special attention is needed in design and on-site

to anticipate air leakage paths in constructions

using a perforated liner or deck.

A StramLiner/WalkLiner vapour control layer

is, to a great extent, unaffected by weather

during installation and easily checked before the

SpeedDeck is installed:-

- externally, the SD Seal tapes and liner screws

can be inspected.

- internally, missing filler blocks are

easily spotted due to visible light at the

perimeter junctions.

Falls

The minimum actual fall for SpeedDeck is 1°, with

the basic provision that water does not pond for a

long period after rainfall. To achieve a 1° minimum

actual fall may require designing for 2° - 2.5° to

overcome structure dead-load deflections and

installation tolerances.

Curved roofs go through a position of zero fall at

the apex. This is not detrimental to the roof due

to the limited extent and position of the zero fall.

Even under 1 in 50 year rain storms and with very

long low pitch sheet lengths, the flow rates from

SpeedDeck result in minimal depths of flow (85m

sheet length, 0.056l/s, 6mm depth of flow).

Airtightness

The control of air leakage is now a requirement of

the building regulations with most buildings to be

the subject of air tightness testing.

The permitted air leakage rate is 10m3/hr/m2at a

pressure difference of 50Pa.

SpeedDeck’s approach to airtightness employs

simple, low cost methods that are easy to

install, and straightforward to check, yet have

a significant impact on running costs, energy

efficiency and comfort, and help the building to

pass the airtightness tests. SpeedDeck has carried

out airtightness testing on sealed StramLiner/

WalkLiner. The simple, positive and easy to check

method of sealing a SpeedDeck roof gave the air

leakage rates given in the table.

Note that any penetrations, rooflights/ pipes etc

should also be sealed to the liner. Use white dektite

soakers internally for pipes.

A typical 2000m2 roof with 240 lm of eaves/

ridge, 66.7 lm of verge, 1960 lm of side lap and

360 lm of end lap would have an air leakage of

0.1 m3/hr/m2 at 50Pa through the roof. This is

a fraction of the permissible air leakage rate

of 10m3/hr/m2 and demonstrates the potential

airtightness achievable by a SpeedDeck roof.

In roof systems with perforated inner profiles

(WalkLiner/ StramLiner/ structural decks) it is

essential that the reinforced polythene StramCheck

vapour control layer is good, any tears repaired,

sealed at perimeters, sealed at penetrations,

continuous over hips and valleys, and robustly

connected to the wall air barrier. The StramCheck

layer is the roof air barrier and so subject to the air

pressure testing.

Also, be aware that the perforated liner or deck

will allow air/ sound/ smoke to travel over the

top of a wall abutting the soffit of the profile.

Suitable measures should be taken at design

and installation stage, both within the roof

construction and under to avoid air/ sound/

smoke flanking the wall.

Breathability

In assessing SpeedDeck for the risk of interstitial

condensation, the Agrément Board allowed a

defect area in the vapour control layer of 10mm2/

m2. This is, in effect, a factor of safety on the

vapour control layer and allows for damage or

workmanship factors.

Breatheable insulation, and the SpeedDeck profile

ensure that an ingress of moisture through this

theoretical defect area can dissipate harmlessly.

Vapour-permeable quilt insulation allows any

moisture vapour present to pass through.

Cold roofs

The SpeedDeck Double-Skin System is effectively

a warm roof. Ventilated cold roof designs are

generally used in refurbishment, where SpeedDeck

is used to over-roof an old BUR or asphalt roof.

The existing roof must be made good to act as a

vapour control layer and any penetration points

for new structure anchorage points sealed. A

sealed StramCheck membrane can additionally

be laid over the existing roof. Any existing vents

must be extended to exhaust outside the roof void,

otherwise they will generate condensation within

the void. The void between the new insulation laid

on the existing roof and the new SpeedDeck needs

to be effectively cross-ventilated.

There may be a risk of some condensation occurring

in a cold roof at certain times of year. If it cannot be

tolerated then the condensation can be controlled

and stopped from dripping by using StramSorb or

SD100 pulled taut immediately under the SpeedDeck.

StramSorb cold roof condensation control

Condensation due to night sky radiation can occur

in single-skin metal roofing constructions, such

as flat-to-pitch conversions, where the insulation

is positioned on the old roof, creating a void

under the new outer sheet. In extreme cases,

condensation water can penetrate into the building,

giving the illusion and discomfort of a roof leak.

Ventilation of the void removes the moisture when

the conditions are right. Where this occasional

moisture cannot be tolerated, SpeedDeck

StramSorb provides a cost effective alternative

solution. It absorbs surface condensation,

preventing drips, until essential ventilation and the

temperature of the metal roof allow the moisture

to dissipate. This factory-applied treatment has

a fleece surface, affording a large drying area for

rapid evaporation.

SpeedDeck StramSorb consists of a soft, textured,

off-white, self-adhesive polyester fleece applied in

the factory to the SpeedDeck profile.

StramSorb is applied to the reverse side of

SpeedDeck prior to roll forming. Areas such as

SpeedDeck’s keyhole ribs do not receive StramSorb

to avoid impairing the clipping action. This does not

affect the function of the StramSorb coating.

StramSorb allows surface condensation to occur,

but retains moisture in its pores (up to 360g/m2)

until evaporation occurs. The textured finish

increases the overall surface area, promoting the

drying rate. Most metal roofs experience rapid

heat gain soon after direct exposure to sunlight.

This, together with adequate roof ventilation,

dissipates the moisture held within StramSorb.

The amount of gap at perimeter details and

ridge to allow ventilation for cold roofs should be

equivalent to a continuous gap of 25mm either

side of a roof. (Source: BRE Guidebook “Thermal

Insulation : Avoiding The Risks”).

A vapour control layer is required in roofs using

SpeedDeck StramSorb. The existing bitumen or

asphalt roof made good or a reinforced polythene

membrane over the old roof can provide this.

StramSorb conforms to a Class 3 Surface Spread

of Flame to BS476;Part 7 and Class M1 (non-

flammable) in French Norm NF.P.92-5. Where

appropriate, fire breaks should be allowed for as

required in the Building Regulations Approved

Document B3.

StramSorb must be isolated from timber items

(including purlins) by waterproof PVC tape

or a strip of bitumen felt and powder-coated

SpeedDeck clips with stainless steel fixings can

be specified for extra corrosion protection to

these items, if desired.

Performance - High Humidity

High-humidity buildings / swimming pools

The roofs of high-humidity buildings and

swimming pools require a different design

approach to that used for buildings with lower

humidities and more normal environments.

Two basically similar constructions are described

in the following sections. One has a solid liner

for no sound absorption; the second has a pan

perforated liner for good sound absorption.

It has to be recognised that swimming pool halls

potentially place quite onerous demands upon

the fabric of the building. A simple example is the

humidity and vapour drive trying to push moisture

vapour into the building fabric. A typical school or

office has an internal vapour pressure of 1.1 kPa,

this doubles to typically 2.2 kPa in a swimming

pool (source BS6229:1982).

The potential for moisture vapour to enter into

the roof is much greater and the SpeedDeck

constructions described provide a good barrier

against that moisture gaining entry in the first

place. However, they accept that no vapour

control layer can be perfect and therefore have

a ventilation/drainage zone where moisture that

does enter can dissipate.

The constructions use components with enhanced

corrosion protection - aluminium, powder-coated

galvanised steel, stainless steel - to provide additional

protection for components in case of condensation.

The constructions

1. The vapour control layer is the most important

item of all. The roof installer should recognise

this and design and install details appropriately.

2. Solid StramLiner consists of 0.9mm aluminium

polyester-coated to one side with all laps

sealed, stitched and taped. Air-seal filler

blocks under StramLiner to reduce air leakage

must not be overlooked. 0.9mm aluminium

StramLiner is not walkable.

3. The vapour check membrane is Stramcheck

AL, an aluminium/polythene reinforced

laminate with all laps sealed.

The vapour check should preferably run from

ridge-to-eaves in one sheet. The membrane

must be sealed to abutments and penetrations,

be continuous over ridges, hips and sloping

valleys and self-draining at the eaves.

Any damage to the membrane must be made

good. Connections to abutments etc. must

be durable and, if necessary, clamped by

securely-fixed metal strips. The VCL should

drape into the liner profile. If pulled taut,

increase IsoBar brackets by 30mm.

4. In cases where the vapour check is not

installed 100% correctly, there will realistically

be some seepage. The zone between the

breather membrane and the SpeedDeck is

ventilated and self-draining and will require

appropriate ridge and eaves detailing.

5. All primary fasteners should be stainless steel

as advised by the fixing manufacturer. While

stainless steel and aluminium are different

materials, stainless steel is better, on balance,

than carbon steel in this application.

6. If sound absorption is required then the liner is

changed to 0.9mm pan-perforated aluminium

StramLiner. Black tissue-faced acoustic batts

are incorporated within the liner troughs

along with aluminium top hats under spacer

brackets. The workmanship and integrity of

the vapour check membrane is paramount.

0.9mm perforated StramLiner is not walkable.

7. 0.9mm solid or perforated aluminium

StramLiner can provide lateral restraint to

the top flange of light gauge purlins. Position

the fasteners either side of ribs in the

unperforated edge and in every pan.

8. For additional peace of mind the specifier can

opt for all galvanised components above the

VCL to be powder-coated for extra protection

(clips, IsoBar, etc).

Detailing and workmanship

Detailing and workmanship need to be of a high

standard to achieve the best vapour control layer

possible as well as a good, consistent insulation

layer with no gaps or omissions, preventing cold-

bridging. Good attention to detailing will also

cut down draughts, reducing energy loss and

discomfort. Close supervision of workmanship by

the roofing contractor is essential.

Performance - Durability

Lightning

Tests on painted steel, painted aluminium and

natural aluminium show that electrical continuity

exists between the SpeedDeck profile and clips.

The resistance measured in tests was <1 ohm for

steel and aluminium SpeedDeck. This indicates

its suitability to be part of a lightning protection

system in compliance with BS6651 without the

need for additional bonding between sheets. In a

typical built up system the clips are connected

metal-to-metal via the steel spacer rail and

carbon steel screws to the steel purlins.

0.6mm and 0.7mm steel SpeedDeck and

0.9mm aluminium SpeedDeck comply with the

requirements of BS 6651 table 5 for the minimum

material thickness to act as a part of an air

termination network.

Durability

By its design, SpeedDeck avoids end-laps and the

ensuing risk of leakage and corrosion. Side-laps

double-interlock and do not rely on sealants.

The ridge includes a mechanical barrier to water

by means of the turn-up. The eaves uses a turn-

down to rapidly shed water.

On steel SpeedDeck, the factory-sheared ends are

factory-protected for increased resistance to end-

peel. Site-cut edges (valleys for example) can be

similarly painted on site.

The life expectancy of SpeedDeck is essentially

a reflection of the durability of each material, in

particular the life of the coating.

Performance - Durability


The coatings on aluminium SpeedDeck can give a false

impression of the overall durability of aluminium. While

Pvf2 may have a minimum life expectancy of 20 years,

the substrate, when eventually exposed, will oxidise

and self-heal, protecting itself from corrosion. The life

of the aluminium substrate is in addition to the life of

the protective paint finish.

200 micron Plastisol and Colorcoat HPS200® by

Corus are robust barrier coatings and resist site

conditions and foot traffic well. Minor damage can

be locally made good using touch-up paint.

Pvf2 on steel is vulnerable to foot traffic damage

and should be handled in an appropriate manner.

Pvf2 or ARS on aluminium are thin coatings but, if

damaged during installation, do not require repair

to maintain their integrity. The aluminium will self-

heal except in particularly onerous conditions.

Over the years, Pvf2 aluminium in typical roofing

colours has shown itself to be an excellent

product with first class resistance to fading and

chalking. There is no discernable paint loss or

significant change in appearance, after 20 years

exposure in urban environments.

Aluminium SpeedDeck with natural stucco-

embossed finish gives the optimum combination of

durability against cost. Aluminium is naturally a very

long life material and, in the stucco form, has no

paint finish to limit the lifespan.

Stucco aluminium is a light grey when first

manufactured and dulls as it develops its patina

over the first few months. The patina oxidised layer

provides protection to the aluminium, promoting a

long life. When the oxidised layer is breached, due

to scratching for example, it is self-healing.

Natural aluminium should be protected from

contamination on site by materials such as lime or

cement dust if stored at ground level. Aluminium

SpeedDeck should be protected from contact with

alkali-bearing materials such as mortar, copper

or materials containing copper (including timber

preservatives), run off from copper or lead materials.

The oxidised consistency of colour of Stucco

aluminium cannot be guaranteed. If appearance

is of prime importance, use pre-painted or

lacquered aluminium.

If stored on site SpeedDeck bundles must be kept under

a ventilated cover and on a slope to drain rainwater.

Contact with strong alkalis (lime/cement etc) must be

avoided otherwise discolouration will occur.

SpeedDeck is installed by experienced roofing

contractors recommended by SpeedDeck Building

Systems Ltd.

To assist in the installation, SpeedDeck provides

a number of items designed to make installation

easier and a smooth operation.

Documentation:- Every delivery is accompanied

by fixing and handling guides.

Tools:- Also provided at delivery is a gauging

template and a notching template. These are

provided free of charge with extra templates

available for purchase. The gauging template

enables the fixing gauge of 510+/-2mm to be

achieved consistently and simply.

Checking:- A SpeedDeck self-check list is available

to allow the roofing contractor’s supervisor to check

the installation as it proceeds for items related to

performance safety. This allows errors to be spotted

and corrected during installation.

Methodstatements

Method statement documents are available on

request from SpeedDeck Building Systems Ltd on

the following aspects of the use of SpeedDeck:-

• On site manufacture

• Handling and storage of coil on site

• Hoisting/Lifting Equipment/Bundle

• Sizes Fixing and Handling Guide

• SpeedDeck Sheet Removal and Replacement

COSHH

COSHH health and safety data sheets on SpeedDeck

components and accessories are available on

request from SpeedDeck Building Systems Ltd.

Deliveryandsite-handling

The SpeedDeck sheets are delivered in banded

bundles with the top sheet carrying a label bearing

the BBA identification mark, including the certificate

number. The maximum weight per bundle is one

tonne. Bundles should be handled using lifting

equipment with a spreader beam (supplied by

SpeedDeck Building Systems Ltd only for the

duration of delivery on loads over 13.6m long) with

slings set at every lifting point on the spreader beam

(nominally 2.5m apart). If storing at ground level on-

site, the sheets should be kept clear of the ground,

supported at 2m intervals and stacked with a slight

fall to shed rainwater.

Note: Stucco aluminium will discolour if exposed to strong alkalis

- i.e. cement, mortar, lime etc.

Loadingout

onRoof

Load roof over main supports.

Ensure frame will carry any point loading applied. Ensure

that all the male ribs are facing in the direction of laying.

This will prevent unnecessary handling and turning

around on the roof. The direction of laying should always

be into the prevailing wind where possible.

Lifting beams and slings provided for the hoisting

operation are tested and have current safety

certificates. Slings are regularly inspected for

damage and their condition is recorded.

Long straps, provided for naturally-curved

SpeedDeck, should be used when hoisting bundles

to the roof. Gently lower the bundles to allow

them to take up the curvature. Individual sheets

will fall naturally to the curvature.

Delivery and Handling


Installation

Pre-curved sheets must be hoisted directly onto

the roof. Special beams and slings are provided by

SpeedDeck, set to match the radius and sheet lengths.

2m x 50m StramCheck reinforced polythene rolls

and 1.6m x 100m SD100 rolls must be handled

carefully to avoid puncturing and must not be

stored on-end. For long-term storage, the rolls

should be protected from ultraviolet light by

remaining indoors or under non-translucent covers.

The polythene should be dry during installation.

WalkLiner

WalkLiner is provided in up to 1.5t to 2t bundles.

The WalkLiner panels are installed to a gauge

of 1020mm (tolerance 1016-1024mm) to suit

SpeedDeck and rooflights if specified. All joints

must be lapped and fixed to the roof purlins. Fix

StramLiner/ WalkLiner with a minimum of one

5.5mm diameter screw with 15mm minimum

diameter washers per trough. Position screws at

least 30mm from sheet ends in the 60mm end laps.

The above is the minimum criteria for WalkLiner

to be regarded as non-fragile. Do not walk on

0.4mm steel or 0.9mm aluminium StramLiner.

WalkLiner (solid and perforated) is walkable up

to 1.8m multi-span.

At spans over 1.8m, stitch StramLiner/ WalkLiner

laps at 500mm centres.

50mm air-seal solid filler blocks must be located

beneath the StramLiner/ WalkLiner profile at details

such as eaves, hips, valleys and ridges. These help

to provide a high standard of airtightness and can

be self-adhesive to the underside. StramLiner/

WalkLiner should be supported, sealed and stitched

to a firm ground at all side-abutments/verges and

at penetrations. At eaves and ridges, StramLiner/

WalkLiner should be fixed with two screws per pan

to help compress the filler block under the profile

and promote airtightness.

All ridge and verge flashings are turned

down in to the profile to deter vandalism and

complete a three-barrier defence of sheet

turn-up/filler block/flashing turn-down.

Turn-down 20° at the eaves

to ensure water neither

tracks back under the sheet

or overshoots the gutter.

Sheet turned-up 90°

water entering at ridge

and verge locations.

HowSpeedDeckworks

�� [email protected]

To check for missing or overlooked StramLiner/

WalkLiner filler blocks, inspect the roof from

within the building during installation. Daylight at

the eaves/ridge will indicate gaps.

Side laps of StramLiner/WalkLiner panels are

sealed with 50mm x 1.0mm butyl/foil SD Seal

which has an adhesive specially formulated to

be effective in typical cold site conditions. Wipe

the liner surface before applying SD Seal. Apply

pressure to SD Seal to give a good bond. Seal end

laps using 5x6mm butyl bead within the end laps.

Any swarf or debris must be removed from the

panels before the liner is covered where required

with StramCheck, which should be laid with the

slope and made continuous by lapping all joints

by a minimum of 75mm and sealing with the

1.5x20mm butyl-strip sealant provided.

The product comes in 2m x 50m rolls and should

be laid continuously over ridges/hips and sealed

to penetrations/abutments.

StramCheck should preferably drain (externally)

at eaves.

StramLiner/WalkLiner


StramCheck should be installed to sag between

StramLiner/WalkLiner ribs. If pulled taut, the

IsoBar bracket depth should be increased by 30mm

to compensate for the reduced insulation void.

Note that if StramCheck is specified, the non-perforated

StramLiner/ WalkLiner laps are still sealed, with SD Seal as before.

IsoBar

IsoBar is fixed through the StramLiner/ WalkLiner

panels to the roof purlins with two hex head screws

per bracket. The mineral wool quilt is packed

tightly around and under the IsoBar spacer, leaving

no gaps and made continuous over ridges/hips etc.

The IsoBar bracket spacing is 1020mm maximum,

or as specified to suit the loading design. The

bracket screws must be appropriate to the purlin

material type and thickness.

Install an anti-sway bracket at 30m max intervals

on each line of IsoBar.

Insulation

The full insulation and membrane construction

should be continued over ridges and hips. Any

gaps or omissions should be avoided.

SD100

The SD100 breather membrane is installed down

or across slope, as required, with minimum 150mm

laps and detailed to drain externally at eaves. SD100

is identified by its light blue colour and printed

SpeedDeck logo and comes in 1.6 x 100m rolls.

SpeedDeck

The pre-assembled starter clip is used at the

beginning of a sequence of SpeedDeck, i.e. at

verges and sides of rooflights. The dimension

from the edge of the structure for the first rib is

established and a straight line square to the eaves

is determined. All starter clips are aligned using a

string line or other straight edge. Clips should be

a minimum of 100mm from the end of the IsoBar/

rail. The starter clip adaptor engages with the

trailing female rib at the start of a roof area.

On curved roofs ensure that the 1st sheet is

plumb and true. Sheets out of plumb may not clip

together. Every SpeedDeck rib must be secured

with a clip at every purlin/spacer.

Installation

Pre-assembledstartercliponfullSpeedDeckclip


Always use the screws provided by SpeedDeck,

which have been designed and assessed for the

purpose of clip-fixing. Be aware of the purlin

thickness and request the correct screws.

Shallow hexagonal-headed SDS20 screws require

the use of the specific SDS20 sockets, supplied

by SpeedDeck.

Use a light touch in driving and do not over-run the

screws - this wears the socket and risks stripping

the thread. SDS20 screws are suitable for fixing

clips direct to IsoBar rails and steel up to 3mm

thick. Consult SpeedDeck for screws for other

applications (hot- rolled steel, fixing via thermal

break pads, stainless steel screws, timber etc).

The ridge end of a sheet is turned-up to vertical

using the correct end of the tool supplied. The

shoulders of the SpeedDeck rib profile must be

hammered flat for 50mm from the sheet end and

a 45° section from the female rib snipped off.

The turn-up end of the tool is inserted over the

end of each pan and rotated through about 90°.

If carried out in-situ, there must be access for the

tool to sit over the profile-end, otherwise the turn

up must be formed before installation.

The first SpeedDeck sheet is positioned over the

fixing clips with the male rib (identified by its anti-

capillary groove) as the leading rib. The centre rib

is engaged by applying foot pressure firmly over

each clip but the trailing rib is kept loose at this

stage. The ridge and eaves overhangs should be

between 125mm and 300mm. Install vented filler

blocks at the eaves, use only SpeedDeck Building

Systems filler blocks.

The next clip is inserted and engaged into the

leading rib of the SpeedDeck sheet and positioned

using the SpeedDeck gauging template. It is

essential to use the template to position the clip

correctly and achieve the gauge of 510mm +/-2mm.

Once the clips are secured using the screws

supplied, the trailing edge of the sheet is engaged

and the next sheet installed. Engage overlapping

ribs by walking the ribs together. This procedure

is continued until the roof is covered.

Fixed-point screws should be installed at the ridge

and hip. At pitches of less than 5°, an SDS20 clip

screw is installed through the male rib into the

clip and covered by the female rib. At pitches

over 5°, a hexagonal-headed screw with a bonded

washer is installed into the ridge spacer in the

centre of each pan. It should be positioned to be

hidden by a ridge flashing where possible. For

curved and bow-over roofs, an SDS20 screw is

installed through the male rib into the clip at the

three apex purlins and covered by the female rib.

The end of a sheet must be turned down by 20°

at eaves/valley, using the correct end of the tool

supplied, even on a 1° pitch roof. This permits good

water run-off, prevents run-back under the sheet

and laterally stiffens the pan.

As an alternative, and recommended for curved

roofs, install an angle drip under the eaves,

riveted to each pan with 2 No. Rivets. Refer to

Construction Detail BRO2. Butt the aluminium angle

at eaves positions where sheet lengths change.

Aturn-downoreavesanglemustbecarriedout

toallsheets,irrespectiveofpitch.

For additional security, the interlocking ribs can be

riveted together through the side of the rib head,

25mm from the sheet end at eaves/valley positions.

Every rib at a sloping valley, where the

SpeedDeck has been raking cut, must be secured

with a half clip, fixed with two screws to a

continuous spacer. The raking edge should be cut

with a nibbler or tin snips and, turned-down. A

grinder must never be used.

�0eleco.com/speeddeckSpeedDeck is committed to the environment. Please think before you print.

Steel SpeedDeck sheets are factory-protected at

all sheet sides and ends. Site-cut valleys should be

painted using Beckers clear lacquer, available from

SpeedDeck. The raking edge of SpeedDeck at a

hip must be turned-up. A raking-hip turn-up tool is

available on hire from SpeedDeck for this purpose.

At hips, a sealed-washer hex-head screw can be

used instead of a clip to secure the sheet in the

pan under the hip-cap to a continuous spacer.

A notching template should be fabricated on-

site to allow notches to be marked consistently

and accurately. This can take a similar form to

the notching template for ridges, available from

SpeedDeck. Single-span areas (detail BR09)

should be crown-fixed using stainless steel screws

plus sealed washers to the clips in interlocking

ribs for additional security. This includes short

sheet overhangs, parts of valleys and parts of

hips. If raking valleys or hips are cut at an angle

sharper than 45°, resulting in longer raking

edges, the raking edges should be pan-fixed using

stainless steel screws plus sealed washers at

maximum 450mm centres.

Only the SpeedDeck ribs should be walked on,

to maintain the appearance of all SpeedDeck

materials. Protective boarding should be used in

regular access areas and any area where work is

carried out at flashings etc. SpeedDeck accepts

installation traffic, but regular or heavy trafficking

can lead to a diminution in appearance.

At the end of a day’s work the leading edge of

SpeedDeck must be made secure as a temporary

measure. Install a SpeedDeck clip over the male

rib and remove when installation recommences.

Keep the clips separate and re-use only for

securing SpeedDeck at the end of a day’s work, do

not re-use these clips as primary SpeedDeck clips.

• Use boarding where a roof is to be regularly

trafficked.

• Keep other trades off the roof.

• Walk on ribs wherever possible.

• Work off boards if working at one location

for a while on aluminium.

• Points of access to the roof can be the worst

affected and should be protected.

• The engagement of laps and ribs on clips must

be checked by sighting across the ribs in the

direction of laying; any non-engaged laps will be

obvious. All ribs should be walked on to ensure

that sheets are fully engaged on the clips.

• Check that eaves turn-down-angle has

been provided.

• Check that starter clips and half clips are

included where appropriate.

• Check that ridge flashings are fixed to every rib.

• Check that valleys are secure.

To assist the installer in self-checking during

construction, the checklist can be used.

SpeedDecksheetreplacement

It is possible to remove and replace damaged

straight SpeedDeck sheets. This operation must

be carried out with care by the roofing contractor

with appropriate attention to safe working

procedures. A method statement is available from

SpeedDeck, giving guidance on the removal and

replacement procedure for SpeedDeck sheets.

If the SpeedDeck sheets are to be re-used,

removal should be done carefully so that the ribs

are not distorted.

The clips should always be replaced in case of

damage or distortion to the clips.

The gauging of reinstated or new SpeedDeck

should be maintained between 508 and 512mm.

After replacement, checks should be made to

ensure that laps are fully engaged, the sheets are

fully locked into the clips and ancillary items such

as filler blocks/ridge etc. are completely reinstated.

Reused SpeedDeck sheets should be riveted

together through the interlocking rib sides 25mm

from the sheet end. (refer to SpeedDeck for

information on replacement of curved sheets).

Naturally-curvedandsmooth

pre-curvedSpeedDeck

Naturally-curved and smooth-curved SpeedDeck

are installed in the same way as straight

SpeedDeck, maintaining the simplicity of

installation. Additional general guidance is given

below relating to the installation of naturally or

smooth pre-curved steel or aluminium SpeedDeck.

1. Use double clips supported on a 20mm deep

inverted top hat spacer or ledger plate at the

eaves purlin, supported by an IsoBar spacer

20mm shorter than used over the general roof

area. Use IsoBar bracket at 510mm centres.

2. Use the gauging template to set out SpeedDeck.

On tighter radii clips can be laid ahead of

SpeedDeck using the slots in the gauging

template. Contact SpeedDeck for details.

3. WalkLiner will curve to the same radius as

natural curve SpeedDeck.

4. Purlin top flanges should match the pitch of

the roof at the purlin location to reduce the

risk of marking.

5. Keep foot traffic to a minimum and walk

on ribs wherever possible. This keeps foot

marking at purlins to a minimum. Protect

from following trades.

6. Provide SDS20 screws through the male rib

to the clips at the two/three apex purlins as a

fixed-point fixing. On a ridge-to-eaves curve,

SpeedDeck is fixed in the pan at the ridge

using sealer washer screws.

7. Work off boarding for flashings/ penetrations.

8. Natural curving of roofing profiles involves

a profile manufactured flat being laid to the

structure radius on site. This induces stresses

into the flat pan and any roofing profile,

SpeedDeck or others, can show oil-canning

or the substructure shadowing through due

to this and foot traffic. These effects are

not detrimental and are rarely visible or

commented on from ground level.

9. Ensure that the first sheet is set out true and

plumb. Curved sheets out of plumb (ie. where

the apex is perhaps aligned infront of the

eaves) may not clip together properly.

Tolerances

These tolerances are intended to help achieve a roof giving optimum performance and appearance and

apply to both the structure and to SpeedDeck. Exceeding the tolerances may lead to impaired performance

and/or surface blemishes. Refer to Steel Construction Institute (SCI) document P346, “Best practice

for the specification and installation of metal cladding and secondary steelwork”, section 4.4 Erection

tolerances for purlins and side rails, y=+L/180 or10mm; -L/180 or -5mm.

Notes

a) Choose the smaller value, positive = above design level, negative = below design level, L = purlin spacing. Tolerance is in the level of a

purlin relative to the purlins either side.

b) The incorrect spacing of clips can affect attachment strength.

c) Even at very low slopes, the purlin, or spacer top flat, must match the slope.

d) On curved roofs, the spacer/purlin flats must match the slope at that point. Any errors in purlin level tend to show up more on curved roofs.

Tolerances on profile shape and size conform with the MCRMA guide. Refer also to MCRMA guide No 3 ‘Secret-Fix Roofing’ for further

guidance on tolerances.

Panel Maintenance, Repair and Replacement

Panels are carefully packed and checked to

ensure good condition on delivery. If a panel

is damaged during installation or in service,

replacement or in-situ repairs are possible.

Installed panels should be protected from damage

by other trades. Bottom row panels should be

protected by covering with ply or similar boarding.

Ideally the lower panels will be protected in

service by barriers of some form.

Maintenance

Panels require minimal maintenance beyond

cleansing to maintain appearance.

Minor damage to the coating can be made good

by touching in scratches using colour matched

touch-up paint applied along the line of a scratch

using an artist’s paintbrush. The paint will be air-

drying and while the same colour reference, will

not blend in invisibly.

Repairs to major damage or professional repairs to

minor scratches can be carried out by a specialist

company. Contact SpeedDeck for details.

Washing to restore appearance or remove

stains should be carried out by suitably trained

personnel with safe access, using soft cloths/

brushes and water containing a mild detergent.

The area should then be rinsed using clean water.

Care must be taken not to damage paint surfaces.

Repair

Damaged panels can be repaired on-site by

specialist companies. Contact SpeedDeck for

contact details.

Panel Replacement

Panels that are damaged beyond repair can be

replaced following the procedure described below.

At least 4 fixers are needed to handle two panels

at a time in safety. Refer to detail VIT 120/15.

• A replacement panel, 50mm wide repair

brackets, 15mm x 19mm PVC air seal, vertical

joint insulation strip and a narrow extension nose

piece or socket for the screw gun are needed.

• Remove vertical gasket to either side of the

damaged panel.

• Cut out the damaged panel taking care not to

damage adjacent panels.

• Undo the brackets to the panel below and

replace with the repair brackets. Note: these

should oversail the panel by a sufficient

amount to allow the screws to be inserted via

the vertical joint. Hold panel in place.

• Check the air seal for damage and replace

if necessary.

• Tilt the lower panel out and offer up the

replacement panel. Engage the top joint first,

then the lower joint as it sticks outwards, and

then rotate the panels into position.

• Insert new insulation strip into the vertical

joint. Reinstate the vertical gasket.

• Insert the bracket screws via the vertical joint.

The screw gun drive bit will need to be narrow

enough to access the screws via the 10mm

vertical joint gap. Pre-drilling the screw holes

may assist in driving the screws.
