Manufacture and carbon reductionwww.marleyeternit.co.uk/EnvironmentAssessing the sustainability offibre cement profiled sheeting900114001Our factoriesAll Marley Eternit’s factories in theUK are ISO 9001, 14001 and ISOOHSAS 18001 accredited. This means theyoperate under internationally recognisedstandards and controls providing the best inquality and sustainability for the people workingin them and the products coming out of them.18001Manufacture of fibrecementThis is a low energy process usingreadily available locally sourced or sustainableresources which are natural and abundant.Production waste is recycled into theproduction process.Cement can often be a main contributor to theequivalent carbon dioxide emission during themanufacture of fibre cement products, so wecontinually develop formulations that replacecement by raw materials of low carbonequivalent.As the only UK manufacturer of fibre cementslates and profiled sheeting, we can guaranteefewer delivery-miles for these productscompared to imported products.Water recyclingWe’re saving around 2,000 m 3of water each year through recyclingwater recovered from manufacturing processes.Reducing wasteWherever possible, all our sitesrecycle waste rather than send it tolandfill. We’ve installed waste-to-heat powerplants at two of our factories, converting allsorts of waste – from cement bags toirreparably damaged timber pallets – to heat.Our Keele plant recycles all green waste andre-uses waste water. as well as having its ownnatural water sources (boreholes).We have various schemes in place where were-use all waste concrete material within ourproducts as well as using locally importedre-usable material from other manufacturers.The level of recycled material we use currentlyin the production of concrete tiles is 20%.Energy usagemonitoringand savingMany organisations simply rely on informationfrom a single meter to gauge energyconsumption.We’ve introduced sub-meters and mobilemetering that enable us to identify precisely howmuch energy is used by different facilities onour sites. This means that energy usage can bemanaged in a much more sophisticated andinformed way.Electricity, gas, oil and water consumption ismeasured and compared across our factories.The monthly data helps us to identify whereimprovements can be made. At one site weperiodically use methane produced by a locallandfill to generate the heat which cures tilesand heats the workplace.Reducing our carbon footprintMarley Eternit is developing its sustainableCarbon Management Programme aimed atreducing carbon emissions and improving its‘carbon footprint’. We have set ourselves atarget to reduce the carbon emissions frommanufacturing processes over six years from anindex of 100 (based on 2006 data) to an indexof 75.The monitoring of Marley Eternit’s carbonreduction target is overseen by an internalEnergy Action Group, which uses asophisticated computer based energymanagement system which monitors energyusage and CO 2 generated, against tonnageof material produced.Lower embodied energyproductsA product manufactured using a process whichuses less energy and less primary raw materialswill generally have a much lower embodiedenergy (the energy used to acquire, process,and manufacture the product, including anytransportation related to these activities). Theseproducts will be more sustainable and will helpspecifiers to attain higher ratings againstsustainability requirements set out in currentlegislation.When used in A + ratedconstructions, fibre cementprofiled sheeting can achieve3 credits in the materialscategory of the Code forSustainable Homes andcan help achieve ‘Good’ or‘Excellent’ ratings for BREEAMfor non-residential buildings.BRE Green Guide on-lineOur range of fibre cement profiled sheeting isUK manufactured and as such, is the only fibrecement profiled sheeting able to achieve A + or Aratings in the BRE Green Guide to Specification.The BRE ‘Green Guide’ onlinewww.thegreenguide.org.uk contains a listingof building materials and components which areassessed in terms of their environmental impactacross their entire life cycle – from ‘cradle tograve', within comparable specifications.DescriptionLow pitched roofThe Green Guide contains more than 1200specifications used in various types of buildingwhich examine the relative environmentalimpacts of the construction materials commonlyused in six different generic types of buildingcovering six sectors.Materials and components are arranged on a‘building element’ basis so that designers andspecifiers can compare and select comparablesystems or materials that may be used in, say,roofs, walls, floors etc.When used in one of the construction types † listed in the table below, fibre cement profiledsheeting achieves an A + rating.† The constructions shown right are recent additions to the ‘Green Guide to Specification’.

Design considerationsSetting out the roofLaying the sheetsRoof sheeting should commence from one end ofthe building at eaves level, rising in vertical tiers,one sheet wide, from eaves to ridge. Wherecranked crown sheets are used, it is especiallyimportant that the slopes are accurately alignedwith each other. Vertical sheeting should also befixed in tiers, one sheet wide, from the lowest levelof the profiled sheeting.PURLINS: the horizontalbars on the roof to whichthe sheets are fixed.The end laps of each row of sheets should form acontinuous straight line from gable to gable andmust not be staggered. Similarly, the side lapsshould be aligned from eaves to ridge.Checking the structureBefore sheeting is commenced, the structureshould be checked to ensure that all purlinsand rails are in a true plane, correctly spacedand securely fixed and adequately restrained.RAILS: the horizontalbars on the wall to whichthe sheets are fixed.Setting out planTypical double slope roof is shown belowwith two-piece adjustable close fitting ridgeand Profile 6 sheets.NoteFor typical mitring detail with 150mm end lap, seefollowing page.Direction of lay: right to left (right hand fittings)Hooded two pieceridge finialTwo piece adjustableclose fitting ridgeC LRidgeRidgecourseNote: Sheeting should be laid in tiersfrom eaves to ridgeMitreBargeboardIntermediatecourseMitre150 minend lapMax purlin centres:Profile 6: 1375Profile 3: 925EavescourseEavesfillerpieceMax purlin centres:Profile 6: 1375Profile 3: 925Direction of lay: left to right (left hand fittings)Max supported overhang:Profile 6: 350Profile 3: 25032 Profiled sheeting design guideProfiled sheeting design guide 33

Design considerationsMitringFixingGeneral guidanceMitring layoutsGeneral guidanceTo avoid four thicknesses of sheeting at theThe procedure for mitring the sheets for single andAll sheets must be fixed in accordance with theTraditional fastenersjunctions of side and end laps, it is necessary fordouble slope roofs is indicated on the mitre plansrecommendations of BS 8219.In certain circumstances it may be preferabletwo of the sheets at each junction to be mitred atthe corners so that they lie in the same plane.Mitres on Profile 6 and 3 sheets should be cut froma point 150mm up the vertical edge from thecorner (or the amount of the end lap) to a point70mm (131.2mm for Profile 3) along the horizontaledge, ie, the width of the side lap by the length ofthe end lap.Mitres on fibre cement lining sheets should be cutfrom a point 75mm up the vertical edge from thecorner (or the amount of the end lap) to a point43mm along the horizontal edge.Ideally, the gap between mitres should be aminimum of 3mm to a maximum of 6mm.Box mitres should be avoided. The mitred jointis covered top and bottom by the other twosheets, and is thus weatherproof and unseen.below (Figs.1-3).On double slope roofs with two-piece adjustableclose fitting ridges or cranked crown ridges, oneslope must be laid left to right and the other rightto left.When cranked crown ridge pieces are used, bothtop courses of roofing sheets and the crankedcrowns should be mitred.When using 2 piece ridges, the top courses ofsheets and the ridges should not be mitred.NoteAll mass-produced building products are allowed certaindimensional tolerances. This applies to both profiled fibrecement sheets and steelwork. Because of these permittedvariations in dimensions, regular checks should be carriedout on measurements at mitres, and adjustments made asand when necessary.Profiled sheeting should always be fixed with2 fasteners per sheet per purlin.The selection of the correct sheet fastener isextremely important. The integrity of the roofcovering, type of purlin or rail system, andweatherproofing with washers and caps all mustbe considered to avoid premature failure, corrosionor a leaking roof.Topfix fastenersSelf-drilling, self-tapping ‘topfix’ fasteners aregenerally used to fix P6 sheets to the purlins.These fasteners drill through the P6 sheet, creatinga 2mm oversize hole and self tap into the purlin.It is important that the fasteners are installed usingthe correct power tools, which should have anadjustable depth setting device to ensure thewashers are seated correctly. The fastenersto use traditional fasteners such as hook bolts,crook bolts and drive screws. There are, however,additional health and safety implications to considerwhen using these fixings.The fasteners are generally 8mm diameter forProfile 6 and are fixed through 10mm diameterpre-drilled holes in the sheet. For hook and crookbolts, the fixing should be positioned 4mm upslopefrom the back leg of the purlin. Drive screws shouldbe located centrally on the purlin.Profile 3 sheets are generally fixed using 6mmdiameter fasteners and an 8mm diameter holeshould be drilled through the sheet.NotesWhen fixing to timber purlins, BS 5268: Structural use ofTimber, recommends that the minimum edge distance ofthe fixing should be five times the fixing diameter to avoidundue splitting of the timber.(See typical mitring details below.)NoteMitres must not be cut in situ.typically have different drill points to suit thedifferent purlin types:When following the recommendations of thefastener manufacturers, please give particularFasteners should be installed perpendicular to the plane ofthe roof.With some types of insulated cladding, or where sealant hasbeen used, sheet settlement can take place.

This materialcharacteristic has a significant effect in reducingcondensation occurrence.of natural finish fibre cement sheets. The acrylicpaint finish provides added protection against manyacids, alkalis and solvents normally found in theatmosphere.Where fibre cement is to be used in particularlyaggressive atmospheres, with higher than normalconcentrations of acids, alkalis, fats or salts, pleasecontact the Marley Eternit Technical Department atMeldreth for advice.BiologicalProfiled sheeting is vermin and rot-resistant, butlichen may grow on the outer surface. For adviceon removal, please contact the Marley EternitTechnical Department.Effects of low and hightemperatureProfiled sheeting is designed to be minimallyaffected by frost or climatic temperature changes.For buildings in which higher than normaltemperatures occur, or in areas which are expectedto be subjected to sudden changes intemperature, special considerations may benecessary.

RidgesCranked crown ridgesCranked crown ridge pieces are one-piecefittings for closing off Profile 6 sheeting at thecrown of a roof.They are made with an accurate profile, givinga precise fit and are manufactured in pitchesof 5° to 22 1 /2° in 2 1 /2° increments. These sheetpitches can be used with any roof pitch from5° to 23 1 /4°. (See table opposite.)Available girths are 750 and 900mm.Before laying cranked crown ridge pieces,it is important to ensure that the sheets onboth roof slopes are aligned correctly.The ridge purlins should be positioned so thatthe fixings are located not less than 100mmfrom the ends of the cranked crown ridgepieces. (See Figs.1 and 2).To form a non-fragile ridge detail, the crankedcrown should be lapped by 300mm onto thesheeting on each side of the ridge.Where cranked crown ridge pieces overlap,both the cranked crowns and the lowersheets are to be mitred on each roof slope.100mm min.General methods ofapplicationFigs 1 and 2 are typical details which, using thesame principles, can be applied to situations otherthan those illustrated.Cranked crown Roof pitchessheet pitch from to5° 5° 5 3 /4°7 1 /2° 6° 8 1 /4°10° 8 1 /2° 10 3 /4°Built up systemsPlease contact Marley Eternit for further details.Ventilating cranked crown ridge pieces12 1 /2° 11° 13 1 /4°Profile 6sheet300mmFig.1 – Cranked crown fixingsStandard 300mmradius750 or 900mm girth to underside of sheet100mm min.Profile 6sheetFig.3 – Typical built up systemThese match in with cranked crown ridge piecesand give ventilation whilst providing reasonableweatherproofing.They may be used in continuous runs, orintermittently with plain cranked crown ridge pieces.If used in continuous runs, provide one standardcranked crown ridge piece at each end of thebuilding.

Roof windowsPhotovoltaics and profiled sheetingRoof windows can generally be incorporated into a profilesheeted roof provided they have a flashing kit suitable for thedepth of profile. It is, however, important that the positions ofthe windows are coordinated with each other and with thesheeting layout at an early stage of the design.There are various types of fixing systems for PVpanels, most of which have brackets fixed throughthe fibre cement sheets to the purlins.It is important that there is a sheet lap immediatelybelow the roof window so the malleable flashingcan dress over the course of sheets below, beforethe sheets to the side of the window are installed.It is preferable, but not essential that there is asheet lap immediately above the window.The windows should be positioned to avoid anarrow strip of sheet to the side of the rooflight.If the water barriers on the flashing kit are not deepenough to provide a weathertight detail, particularlywhen considering wind driven snow, Marley Eternitmay be able to provide some solutions.In some cases, this method of fixing can affect thelong term performance of the roof covering so apreferred solution is to fix a secondary frameworkabove the roof sheets. A series of stub columnscan be fixed on top of the structural frame tosupport a secondary rafter above the roof surface;the PV framework can then be fixed to thissecondary rafter. The holes through the sheetingfor the stub columns should be weathered withpipe flashings, possibly in conjunction with a metalapron flashing that extends up to the ridge.When selecting a fixing method for PV panels, thefollowing points should always be considered:• Fibre cement profiled sheets should always have2 fasteners per sheet width per purlin, the fixingpositions being in the first full corrugation oneach side of the side lap. There should be noadditional fasteners fixing the sheets to thepurlins. The fasteners should be fixed through2mm oversize holes in the sheet to allow forexpansion/contraction and differential movement.• The roof structure should be designed for theadditional loading of the PV system, and alsofor possible additional snow loadings as thePV panels could increase the build up of snow.It has been shown that there may also be anincrease in wind loadings after PV panels havebeen fitted to a roof.• The additional loading on top of the profiledsheet will increase the downslope loadings onthe fasteners and rotation of the purlins. Can thefasteners withstand this loading? Where Zedpurlins are used, is the purlin thicknessadequate to prevent the fasteners rotatingdownslope? Is the purlin restraint systemadequate to withstand the additional downslopemovement/rotation?• The installers must work from crawling boardsto minimise damage to the sheets and to avoidwalking on a fragile roof. As fibre cementembrittles with age, existing roofs will be morevulnerable to damage from foot traffic and whenworking on the roof.• There should be no foot traffic directly on thesheet surface when cleaning the PV panels.If access onto the roof surface is required,crawling boards or roof ladders should be used.When considering installing PV with Marley EternitProfiled Sheeting, please contact the TechnicalDepartment.74 Profiled sheeting design guideProfiled sheeting design guide 75

VentilationAgricultural systems (numbered 1 to 4)* Please note that agricultural ventilation systems are generally used on roof pitches of 15° and above.Good ventilation is a critical factor in the design of a building,whether it be new construction or conversion and whether foran agricultural, commercial, industrial or residential application.Marley Eternit offer four main types of ventilation system foragricultural structures*, one system developed specificallyfor industrial applications and two for domestic. These aredesigned to meet almost any ventilation requirement.System 1: Open ridgesThere are two types of open ridge: unprotectedand protected. Both provide efficient ventilationwhilst simultaneously reducing draughts.Rain falling into the ridge area will be drained awayabove the profiled sheeting. It is, however,important to protect the supporting rafters from theelements with a flashing.Advantages of open ridges• Provides an efficient outflow of air• Designed to fit any roof design, but particularlysuitable for spaced roofingThe critical factor for open ridge ventilation is theair gap marked ‘y’ on the diagrams below. Theclear width of this air gap relates to the numberof animals that will be kept inside the building.Marley Eternit recommend that professional advicebe sought during construction in order to establishthe optimum air space.To meet the requirements of HSG 33, the gapbetween the purlins at the apex of the roof shouldbe no more than 300mm. For this reason we showtwo purlins on each side of the apex. Theventilation gap (y) is therefore limited to 250mm.Protected open ridges (Fig.2)In this ventilation system, the ridge units should beinstalled in the same fashion as for unprotectedopen ridges. Additionally, however, the ridge unit isbridged at 750mm centres by galvanised metal strapsmanufactured to suit the pitch of the roof. Thestraps are fixed at an angle of 5° from the horizontal,semi-compressed flat sheeting is then bolted to thestraps along the length of the ridge to form a cover.This cover must be positioned 20mm minimumbelow the top of the upstands of the ridge unitsand the total gap between the cover and the open• Allows rain to be channelled away over the roofUnprotected open ridges (Fig.1)Ideal for farm buildings with central cleaningridge (x) is such that x = y2passages.

Sheet lengthsshould be calculated to give a minimum end lapof 150mm.

Sheeting stacks should generally notexceed 1200mm high unless a level concrete baseis available, in which case the maximum height is1500mm. A separate stack should be made ofeach length of sheet; if this is not possible, stackwith longest sheets at the bottom and the shortestat the top. It is important when stacking Profile 6sheets on site that the smaller ‘under rolls’ are allon the same side of the stack. Sheets shouldalways be stored weather (smooth) side upwards.Stacks of sheets should not be stored in full sunduring the summer months as the differentialWhen handling sheets, lift by the ends only.Natural Grey sheetsThe plastic wrapping should be retained for as longas possible to control the environment around thesheets. Once the pack has been opened, or if thewrapping is damaged and allowing the ingress ofwater, the sheets should be stored under cover.Coloured sheetsColoured sheets should be stored under cover atall times, preferably inside a building, but if this isnot available they can be stored under a tarpaulin.The tarpaulin should be spaced off the top andsides of the sheets to allow effective air circulationPreferably sheets should be cut at ground levelon suitable rigid supports using hand or poweredsaws. Powered saws should be of the reciprocatingsaw type and NOT disc or circular blade devices.Experience has shown that hand or powered sawblades having 3-3.5mm tooth pitch are most suited.NotesWhen roofing buildings where there will be higher than normaltemperatures (e.g. buildings housing foundries or kilns),cement based sheets should be stored near a heat sourceprior to fixing, and be fixed on a dry day.
