Kingspan taper zero ODP Systems

INSULATION & DRAINAGEThere are many critical factors which must be takeninto consideration when designing a flat roofconstruction. Two of these factors – insulation andrainwater run–off can be addressed with one productrange: Kingspan Thermataper zero ODP Systemsfrom Kingspan Insulation Limited.

Kingspan Thermataper zero ODP Systems areavailable in a range of facings which means they canbe used under most waterproofing systems.

A SOLUTION TO WATER PONDINGA high proportion of flat roof failures can be traced tothe inability of the roof to shed rainwater from thesurface, leading to the formation of water ponds.Ponding of rainwater can seriously decrease thedesign life of the roof by subjecting the membrane toattack from many sources such as:● thermal stress;● alkaline formation; and● mould growth.

Excessive ponding can also increase roof loading,causing further deflection of the deck, which onlyadds to the problem of drainage. Patching is not apractical option: the only effective solution is toeliminate the ponding by designing an adequate fallinto the roof.

Kingspan Thermataper zero ODP Systems havebeen developed to solve these problems KingspanThermataper zero ODP Systems encompass arange of tapered insulation boards, which can bedesigned to provide adequate roof falls.

NEW FLAT ROOFSOn new roofs, the use of Kingspan Thermataperzero ODP Systems eliminate the need to incorporatea fall into the design of the structure, which canrequire complex structural supports (e.g. on metal roofdecks or firrings).

Using Kingspan Thermataper zero ODP Systems toachieve the requirements of the new BuildingRegulations/Standards could yield a saving of at least21% over the cost of using alternative methods tocreate a fall in a flat roof for drainage purposes.

Kingspan Thermataper zero ODP Systems are alsoa simpler alternative to screeding as they do notpresent the risk of an overloaded structure due toexcessive screed depths, avoids a wet trade andavoids the need for the drying out of screeds.

Kingspan Thermataper zero ODP Systems areestimated to be as little as 1% of the weight of asolution using screed to falls with a flat insulationboard.

Because Kingspan Thermataper zero ODP Systemsdo not need time to dry out, they save time in thescheduling of a construction project. A recent analysisof screed to falls systems shows that, in the examplesanalysed, they may require between 100 and 200days to dry.

REFURBISHMENT OF EXISTING FLAT ROOFSOn existing roofs, Kingspan Thermataper zeroODP System and a new waterproofing system can belaid on top of the original waterproofing. This eliminatesthe need for stripping down the roof to deck level, andthe provision of a vapour check is not required.

The existing insulation/substrate and waterproofingmust be sound to provide a satisfactory surface for theKingspan Thermataper zero ODP System. In allcases, the risk of interstitial condensation must be fullyassessed (please see ‘Heat Loss/Condensation Risk’ onpage 8).

Kingspan Thermataper zero ODP Systems comewith a first class design package, which is availablefrom initial concept design through to the completionof the project.

This ensures that the most cost–effective solution forany problem is identified and that the end result is aroof, which meets your specification for rainwaterrun–off and insulation requirements.

ROOF SURVEYThe design of a successful Kingspan Thermataperzero ODP System must take several factors intoaccount:● the position of the roof outlets;● the extent of water run–off required;● the dimensions of the roof;● the presence of any existing falls or steps on the

roof; and● the location and dimensions of permanent

projections such as roof lights, vents etc., andperimeter restrictions.

Normally, an architects drawing should suffice fornew roofs. Any additional information required wouldbe requested by our Tapered Roofing Division beforedesign commences.

On existing roofs, a free survey of the roof will becarried out by one of our experienced surveyors tocollect the required information.

DESIGN CONSIDERATIONSUtilising our CAD system, even the most complextapered system can be designed quickly andeffectively, ready for client approval. The design willillustrate the required direction of drainage and willalso take into account U–value, condensation riskanalysis and wind uplift requirements, as well asminimum/maximum rise restrictions. Amendments orrevisions can be easily incorporated.

HEAT LOSS/CONDENSATION RISKIncluded in the design service is the calculation ofcondensation risk in accordance with BS 5250: 1989(1995) (Code of practice for control of condensation inbuildings) and as defined in BS 6229: 1982 (Code ofpractice for flat roofs with continuously supportedcoverings), based on the psychometric conditions for agiven occupancy/building use.

It is possible to design for minimum or average U–valuesdependent on the client's requirements. However, thecompleted scheme ensures that any dew point ispredicted above the vapour control layer at the minimumboard thickness, whilst also ensuring any condensationrisk is within the safe limits of tolerance of the insulationand the guidelines of BS 6229: 1982 (Code of practicefor flat roofs with continuously supported coverings).

THE TAPERED ROOFING DRAWING SERVICEKingspan Insulation’s Tapered Roofing Departmentoffers a drawing service that allows existing plans tohave the Kingspan Thermataper zero ODP Systemincorporated quickly and effectively. Designs can besupplied in the following ways:● by *e–mail to [email protected] ;● on a *computer disk/CD ROM; or ● on a drawing.

GENERAL INFORMATION

SUSTAINABILITYIt is widely recognised that there are four main globalenvironmental sustainability issues: global warming,non–renewable resource depletion, toxic pollution and ozone depletion, and that these global issues far outweigh any local sustainability issues in their need forimmediate attention and potential impact from inaction.

Recent studies have shown that the first three issuesare essentially one. The extraction and consumption(burning) of fossil fuels is by far the most significantcontributor to global warming, non–renewableresource depletion and toxic pollution.

Therefore, saving energy by specifying the lowest U–value possible and using zero ODP insulationmaterials are the best actions to take when consideringsustainability for the insulation requirements of a building.

Kingspan Thermataper zero ODPSystems is manufactured without the useof CFCs/HCFCs and has zero OzoneDepletion Potential (ODP).

In the past, erroneously, the relativesustainability of insulation materials has been comparedon the basis of embodied energy. It is now known thatthe embodied energy of insulation materials isinsignificant compared with the energy saved byinsulation over the lifetime of a building in which it isused and so is of limited importance. However, it is amatter of social responsibility to state the environmentalimpact in the manufacture of a product, and a full LifeCycle Analysis (LCA) rather than embodied energy isrecognised as the preferred tool to achieve this.

An LCA, independently certified by theBRE, has been carried out for UKproduced Kingspan Thermataper zeroODP Systems and a copy is availablefrom Kingspan Insulation, see rear cover.Kingspan Insulation Limited is the first insulationmanufacturer to publish openly such information.

AVAILABILITYKingspan Thermataper zero ODP System isavailable through specialist insulation distributors andselected roofing merchants throughout the UK, Irelandand Europe.

PACKAGINGThe boards are supplied in labelled packsshrinkwrapped in polythene. The labels show productname, board size, type and quantity. Each packcontains one board type which facilitates the laying ofthe system.

STORAGEThe packaging of Kingspan Thermataper zeroODP System should not be considered adequate forlong term outside protection. Ideally boards should bestored inside a building. If however, outside storagecannot be avoided the boards should be stackedclear of the ground and covered with a polythenesheet or weatherproof tarpaulin. Boards that havebeen allowed to get wet should not be used.

HEALTH AND SAFETYKingspan Insulation products are chemically inert andsafe to use. A leaflet on this topic which satisfies therequirements set out in the Control of SubstancesHazardous to Health Regulations 1988 (COSHH) isavailable from our Technical Services Department (seerear cover).

Warning – do not stand on or otherwise support your weight on theseboards unless they are fully supported by a load–bearing surface.

Kingspan Thermataper TT46 zero ODP Only: Please note that the reflective surface on this product is designed toenhance its thermal performance. As such, it will reflect light as well asheat, including ultraviolet light. Therefore, if this board is being installedduring very bright or sunny weather, it is advisable to wear UV protectivesunglasses or goggles, and if the skin is exposed for a significant periodof time, to protect the bare skin with a UV block sun cream.

WATER VAPOUR CONTROL The need for a separate vapour control layer withKingspan Thermataper TT40 zero ODP in a warmroof construction should be assessed in accordancewith BS 5250: 1989 (1995) and as defined inBS 6229: 1982. A minimum vapour control layershould consist of a coated roofing felt complying withBS 747: 2000 Type 3B, or any appropriatemetal–cored vapour control layer.

Allowance should be made for the adequate bonding ofthe vapour control layer to the deck so as to provide asuitable surface onto which the Kingspan ThermataperTT40 zero ODP is to be laid and to provide a sufficientresistance to wind up–lift (see ‘Wind Loading’ page 9).

TYPICAL U–VALUES

Kingspan Thermataper TT40 zero ODP can easilymeet all U–values required for compliance withBuilding Regulations/Standards revised after the year2000. A detailed U–value calculation together withcondensation risk analysis should be completed foreach individual project. Please call our TechnicalServices Department for assistance (see rear cover).

SITEWORK

LAYING PATTERNThe Kingspan Insulation working drawings willindicate the area of the roof to be covered, theminimum insulation level, fall direction and pitch of thetapered system. The location of each board type willbe indicated clearly on the drawing and each packwill contain one board type only.

Ridges, hips and valleys will be marked on thedrawings, together with the setting out, commencementpoints for laying of the boards. The flat packer boardsused to raise the height of the tapered system shouldbe laid so that where possible they are staggeredwith respect to the tapered boards on top. The packerboards should preferably be bonded in hot bitumen(or see ‘Mechanical Fixings’).

FIXING OVER METAL DECKSOn metal decks Kingspan Thermataper TT40 zeroODP should be laid into hot bitumen (max.temperature 240°C) mopped or poured over thevapour control layer which has been bonded to thedeck crowns. Alternatively the boards can be securedusing mechanical fixing systems. The KingspanThermataper TT40 zero ODP boards should belaid break–bonded with all joints lightly butted, andwith their long edges at right angles to the troughopenings, or alternatively, diagonally across thecorrugation line. Whichever system is chosen, caremust be taken to ensure that all joints are supportedby the deck. Taping of the joints is not required.

FIXING OVER CONCRETE DECKSConcrete decks should be clean, dry, without largeprojections, steps or gaps. To ensure an adequatebond between the vapour control layer and theconcrete deck, the concrete or screeded surfaceshould be suitably primed, in accordance with thespecified manufacturer’s instructions. The vapourcontrol layer should be fully bonded to the deck andsimilarly the Kingspan Thermataper TT40 zeroODP to the vapour control layer by laying into hotbitumen mopped or poured over the vapour controllayer. Alternatively the boards can be secured usingmechanical fixing systems. The boards should be laidbreak–bonded with all joints lightly butted.

FIXING OVER PLYWOOD DECKSThe Kingspan Thermataper TT40 zero ODP shouldbe fully bedded in hot bitumen over a continuousvapour control layer which has been nailed or fullybonded to the deck with laps at the side and endssealed with hot bitumen. Alternatively the boards canbe secured using mechanical fixing systems. The jointsshould be break–bonded and the boards laid at rightangles to the edge of the roof or diagonally acrossthe roof. All joints should be lightly butted.

FIXING OVER TONGUE & GROOVE DECKSOn timber tongue and groove decks, the vapourcontrol layer should be nailed. During the laying ofthe Kingspan Thermataper TT40 zero ODP, thenail heads will become sealed in hot bitumen to thevapour control layer by the subsequent bonding of theroof boards. The Kingspan Thermataper TT40 zeroODP system is then applied as described underplywood decks.

MECHANICAL FIXINGSThe number of mechanical fixings required to fix theKingspan Thermataper TT40 zero ODP boards willvary with the geographical location of the building,the topographical data and the height and width ofthe roof concerned.

Each fixing should incorporate a square or circularplate washer (70 mm x 70 mm or 75 mm diameter).

A minimum 5 No. fixings should be placed within theindividual board area and be sited >50 mm and<150 mm from the edges and corners of the boardgiving a minimum fixing rate of 3.47 fixings persquare metre (1200 x 1200 mm boards). Packerboards (if required) should be secured using a singlefixing prior to the overlay of the KingspanThermataper zero ODP System.

DAILY WORKING PRACTICEAt the completion of each day’s work, or wheneverwork is interrupted, a night joint must be made inorder to prevent water penetration of the roofconstruction.

CUTTINGCutting should be carried out using a fine toothedsaw or by scoring with a knife and snapping theboard over a straight edge and cutting the facing onthe other side. Ensure accurate trimming to achieveclose butting joints and continuity of insulation.

Kingspan Thermataper TT46 zero ODP is taperedinsulation designed for use under PVC and EPDMsingle–ply mechanically fixed roofing systems.

ROOF WATERPROOFINGKingspan Thermataper TT46 zero ODP is suitablefor use with most mechanically fixed PVC or EPDMwaterproofing membranes.

Please note: Kingspan Thermataper TT46 zeroODP is not suitable for use with bitumen based built–up roofing systems or mastic asphalt.

WATER VAPOUR CONTROLThe need for a separate vapour control layer withKingspan Thermataper TT46 zero ODP in a warmroof construction may be assessed in accordance withBS 5250: 1989 (1995) (Code of practice for controlof condensation in buildings). Warm roofs aredescribed in greater detail in BS 6229: 1982 (Codeof practice for flat roofs with continuously supportedcoverings). A minimum vapour control layer shouldconsist of a 1000 gauge polythene membrane.

The specified vapour control layer should have aminimum 150 mm side and end laps which should beadequately sealed. The membrane should also be turnedup, but not sealed, to all vertical surfaces which abut theroof, to a minimum height of 250 mm and shouldoverhang the verge or gutter by the same amount.Before applying the roof finish, the projecting 250 mmof the vapour control layer should be turned over theinsulation and sealed down to form an envelope.

TYPICAL U–VALUES


SITEWORK


Ridges, hips and valleys will be marked on thedrawings, together with the setting out, commencementpoints for laying of the boards. The flat packer boardsused to raise the height of the tapered system shouldbe laid so that where possible they are staggered withrespect to the tapered boards on top.

FIXING OVER METAL DECKSOn metal decks Kingspan Thermataper TT46 zeroODP should be laid over the vapour control layer.The boards are normally secured using mechanicalfixings appropriate to the substrate. The KingspanThermataper TT46 zero ODP boards should belaid break–bonded with all joints lightly butted, andwith their long edges at right angles to the troughopenings, or alternatively diagonally across thecorrugation line. Whichever system is chosen, caremust be taken to ensure that all joints are supportedby the deck. Taping is not required.

FIXING OVER CONCRETE DECKSConcrete decks should be clean, dry, without largeprojections, steps or gaps. The boards are normallylaid over the vapour control layer and all securedusing mechanical fixings and washers. The boardsshould be laid break–bonded with all joints lightlybutted. The boards can also be restrained through theuse of ballast.

FIXING OVER TIMBER DECKSTimber decks should be clean and free of largeprojections, steps or gaps. On timber decks,Kingspan Thermataper TT46 zero ODP should belaid over a vapour control layer, the side ends andlaps of which have been sealed. The board arenormally secured using mechanical fixing systems andwashers. The boards should be laid break–bondedwith all joints lightly butted.

MECHANICAL FIXINGSThe number of mechanical fixings required to fix theKingspan Thermataper TT46 zero ODP boards willvary with the geographical location of the building,the topographical data and the height and width ofthe roof concerned. Each fixing should incorporate asquare or circular washer (70 mm x 70 mm or75 mm diameter). The requirements for securing thewaterproofing membrane should be consideredseparately.

A minimum 5 No. fixings should be placed within theindividual board area and be sited >50 mm and<150 mm from the edges and corners of the boardand be placed within the individual board areagiving a minimum fixing rate of 3.47 fixings persquare metre (1200 x 1200 mm boards). Packerboards (if required) should be secured using a singlefixing prior to the overlay of the KingspanThermataper TT46 zero ODP system.

The requirement for additional fixings should beassessed in accordance with BS 6399: Part 2: 1997(Code of practice for wind loads).

Where alternative mechanical fixing systems that notrely on large washers are specified, such as barfixing systems, the specified system must give similarrestraint to the board as would be attained by the useof conventional washer and washer systems.


CUTTINGCutting should be carried out using a fine toothedsaw or by scoring with a knife and snapping theboard over a straight edge and cutting the facing onthe other side. Ensure accurate trimming to achieveclose butting joints and continuity of insulation. 17
