* The breathable sarking membrane can be placed over thecounter battens, draped to provide for drainage and overlainwith tile/slate battens. This will yield a marginally betterUvalue but it will be more difficult to seal the breathablesarking membrane effectively.

** The requirement for a vapour control layer and/or under tileventilation should be assessed to BS 5250: 1989 (1995).Vapour check plasterboard or a separate vapour control layercan be used as preferred.

*** Kingspan Thermawall TW56 zero ODP contains an integralvapour control layer.

**** If tiles are to be used then this normally necessitates the use ofcounter battens and tiling battens over the breathable sarkingmembrane to allow for water drainage and attachment of thetiles.

5An additional benefit of two layer systems and theInsulation Over Rafter approach (see Figure 1, 2, 5 & 6)is that thermal bridging caused by the rafter is preventedand the potential for pattern staining in the position of therafters is completely avoided. The choice maybeinfluenced by the available headroom and concerns overthe depth of bargeboards.

Approaches with a layer of insulation over rafter arelikely to yield very large fascia boards and sogenerally, between and under rafter insulationapproaches are probably more desirable e.g. (Figures 1 and 2).

Note: However, where the choice is for two layers,the layer with the greatest effective Rvalue should beplaced uppermost in order to prevent condensationbetween the two layers.

UNVENTILATED ROOF VENTILATIONCONSIDERATIONSUnventilated roof approaches create a warm pitchedroof space, which does not require cross ventilation.Recent research suggests that sealing an unventilatedroof, yields a more energy efficient roof as theimpacts of ventilation and incidental infiltrating coldair are negated. Therefore, if creating an unventilatedroof, it is preferable to fully seal all joints in thebreathable sarking membrane with tape. Any watervapour reaching the breathable sarking membraneescapes without condensing. There is then adequateair movement beneath the tiles to dissipate this watervapour to the outside atmosphere. Tape for sealingjoints in the breathable sarking membrane should bespecified in accordance with the recommendations ofthe breather membrane manufacturer.

The requirement for a vapour control layer and/orundertile ventilation should be assessed to BS 5250:1989 (1995) (Code of practice for control ofcondensation in buildings). Vapour check plasterboardor a separate vapour control layer can be specified,as preferred if required.

Note: Kingspan Thermawall TW56 zero ODP, asused in Figure 1, contains an integral vapour controllayer.

VENTILATED ROOF VENTILATIONCONSIDERATIONSIn these cases the Building Regulations/Standards requirea 50 mm ventilation air gap between the insulation andthe sarking felt, so as to avoid condensation.

The requirement for a vapour control layer should beassessed to BS 5250: 1989 (1995) (Code of practicefor control of condensation in buildings). Vapour checkplasterboard or a separate vapour control layer can bespecified, as preferred if required.

Note: Kingspan Thermawall TW56 zero ODP, asused in Figure 2, contains an integral vapour control layer.

BREATHABLE SARKING MEMBRANEBS 5250: 1989 (1995) (Code of practice for control ofcondensation in buildings) recommends that the vapourresistance of the breathable sarking membrane e.g.Kingspan nilvent TM must not exceed 0.25 MN.s/g.

DESIGN CONSIDERATIONS

SUSTAINABILITYIt is widely recognised that there are four main globalenvironmental sustainability issues: global warming,nonrenewable resource depletion, toxic pollution and ozone depletion, and that these global issues far outweigh any local sustainability issues in theirneed for immediate attention and potential impactfrom 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, nonrenewableresource depletion and toxic pollution.

Therefore, saving energy by specifying the lowest Uvalue possible and using zero ODP insulationmaterials are the best actions to take whenconsidering sustainability for the insulationrequirements of a building.

Kingspan Thermapitch TP10 zero ODPis manufactured without the use ofCFCs/HCFCs and has zero OzoneDepletion Potential (ODP).

In the past, erroneously, the relativesustainability of insulation materials has beencompared on the basis of embodied energy. It is nowknown that the embodied energy of insulationmaterials is insignificant compared with the energysaved by insulation over the lifetime of a building inwhich it is used and so is of limited importance.However, it is a matter of social responsibility to statethe environmental impact in the manufacture of aproduct, and a full Life Cycle Analysis (LCA) ratherthan embodied energy is recognised as the preferredtool to achieve this.

An LCA, independently certified by theBRE, has been carried out for UKproduced Kingspan Thermapitch TP10zero ODP and a copy is available fromKingspan Insulation, see rear cover.Kingspan Insulation Limited is the first insulationmanufacturer to publish openly such information.

UNVENTILATED (SEALED AND UNSEALED) ANDVENTILATED CONSTRUCTIONSThere is generally a choice between either approach,except in the case of refurbishment/loft conversions.In these instances, unless the whole roof is to bestripped, it is impossible to use an unventilated roof,because a breathable sarking membrane cannot beinstalled.

Recent research suggests that the unventilated, sealedroof approach yields a more energy efficient roof asthe impacts of ventilation and incidental infiltratingcold air are negated.

POSITION OF INSULATIONDependent on the designed insulation value of theconstruction and the available rafter depth and headroom,different approaches can be taken. It may be necessaryto use two layers of insulation to achieve requiredUvalues e.g. Figures 1, 2 & 5.

6The Uvalue requirements as detailed in theappropriate Building Regulations/Standards can beeasily achieved utilising the appropriate thickness ofKingspan Thermapitch TP10 zero ODP. Thecalculation of Uvalues for pitched roof insulationpurposes is determined by a number of factors: will the loft space be habitable or not; does the ceiling line follow the pitch of the roof or

is it a flat horizontal ceiling; the pitch of the roof (where a horizontal ceiling is

to be used); and rafter centres/depth/width where insulation is

between rafters.

The following examples have been calculated usingboth the combined method and the proportional areamethod. The combined method is required forcompliance with Building Regulations/Standardsrevised after the year 2000. These examples arebased on the constructions shown in Figures 1 to 6with 50 mm wide rafters at 600 mm centres and12.5 mm plasterboard.* If your construction is anydifferent, please consult our Technical ServicesDepartment (see rear cover).

Combined Method Uvalues were calculated usingthe method which has been adopted to bringNational standards in line with the EuropeanStandard calculation method, BS/I.S. EN ISO 6946:1997 (Building components and building elements.Thermal resistance and thermal transmittance.Calculation method).

Proportional Area Method Uvalues were calculatedusing the method detailed in The Chartered Institute ofBuilding Services Engineers (CIBSE) Guide A3(Thermal Properties of Building Structures).

NB when calculating Uvalues using the combined method asdetailed in BS/I.S. EN ISO 6946: 1997, the type of mechanicalfixing used may change the thickness of insulation required. The effectof fixings has been ignored for the purposes of these calculations.Please contact the Kingspan Insulation Technical Services Department(see rear cover) for project calculations.

NB for the purposes of these calculations the standard ofworkmanship has been assumed good and therefore the correctionfactor for air gaps has been ignored.

The figures in the Uvalue tables (pages 79) are for guidance only.A detailed Uvalue calculation together with a condensation riskanalysis should be completed for each individual project. Please callour Technical Services Department for assistance (see rear cover).

*Unless otherwise stated.

TYPICAL UVALUES

POSITION OF BREATHABLE SARKING MEMBRANEThe taping of breathable sarking membrane joints isconsiderably easier to achieve if the membrane isinstalled on a continuous surface (Figures 1a, 1c, 1d,3a, 3c, 3d, 5a, 5b, 6a & 6b).

In these cases, the breathable sarking membrane isinstalled under the counter battens, which provide achannel for water drainage, or in situations with a sarkingboard under a slated roof, directly under the slates (asneither tile battens nor counter battens are used).

Generally, when a continuous surface is available, itwill prove easier to install the breathable sarkingmembrane in horizontal runs, whilst still enabling easysealing between runs.

In some cases with a continuous surface (Figure 1a,3a, 5a & 6a, and 1c, 1d, 3c, 3d, 5b & 6b whencounter battens, tiling battens and tiles replace slatesnailed directly into the sarking board) the breathablesarking membrane can be installed over the counterbattens. This yields a marginally better design Uvaluebut it may be more difficult to seal the breathablesarking membrane joints effectively, as the membranemust be draped over the counter battens in horizontalruns so as to provide a water drainage channel.The air movement allowed by the unsealed membranemay negate the benefit of putting the membraneabove the counter battens.

In situations where there is no continuous surface(Figures 1b and 3b), the breathable sarking membranecan be draped over the rafters in horizontal runs toprovide a channel for water drainage. In this situation,sealing of the breathable sarking membrane joints willprove difficult.

In roofs with no continuous surface, it is preferable,though more difficult, to install the breathable sarkingmembrane in vertical runs with junctions between runssealed by counterbattens placed over the laps inrafter positions. The breathable sarking membrane isinstalled taut as the counterbatten provides a spacefor water drainage.

RECOMMENDED SOLUTIONS FOR NEW BUILD/REROOFINGThe ideal solution for new build or reroofing projects is,therefore, between and under rafter insulation with acontinuous surface for the breathable sarking membraneso that it can be installed in horizontal runs undercounterbattens with laps sealed (Figures 1a, 1c and 1d).

The next best solution is, therefore, between andunder rafter insulation with no continuous surface forthe breathable sarking membrane, and the breathablesarking membrane installed in vertical runs with lapssealed under counterbattens (Figure 1b).

MANSARD ROOFS/WALLSKingspan Thermapitch TP10 zero ODP can be usedfor the construction of insulated tiled or slated mansardroofs/walls. Its application on such contracts is identicalto the standard specification, which is given here.

FIRE STOPSCurrent Building Regulations/Standards should beconsidered with regard to the requirements for and/orprovision of fire stops.

OVER RAFTER LAYER OF INSULATIONOver rafter insulation without a sarking board (Figures5a & 6a), is simply fixed by placing the KingspanThermapitch TP10 zero ODP boards over therafters and under 38 x 38 mm treated softwoodcounterbattens in line with the rafters. Secure thecounterbattens to the rafters by fixing through boththe counterbattens and the Kingspan ThermapitchTP10 zero ODP.

Over rafter insulation with slates fixed directly into asarking board (Figures 5b & 6b), is simply fixed byplacing the Kingspan Thermapitch TP10 zero ODPboards over the rafters with the sarking boardoverlaid. Secure the sarking board and KingspanThermapitch TP10 zero ODP to the rafters by fixingthrough both the sarking board and the KingspanThermapitch TP10 zero ODP.

Over rafter insulation with a sarking board and tileson tiling battens and counter battens, is simply fixedby placing the Kingspan Thermapitch TP10 zeroODP boards over the rafters with the sarking boardoverlaid, and with 38 x 38 mm softwood treatedcounterbattens in line with the rafters. Secure thecounterbattens to the rafters by fixing through thecounterbatten, the sarking board and the KingspanThermapitch TP10 zero ODP.

Boards of Kingspan Thermapitch TP10 zero ODPshould be tightly butted, they may be laid eitheracross or down the line of the rafters and shouldpreferably be laid break bonded. All board jointsrunning from eaves to ridge must occur over rafters.There is no necessity to tape board joints. Apreservative treated stop rail should be secured to therafters close to the eaves (see Figures 9a & 9b).

BETWEEN RAFTER LAYER OF INSULATIONBetween rafter insulation can be installed by threemethods.

In cases where the insulation between rafters is to beflush with the top of the rafters but does not fill the fullrafter depth (Figure 5), install the insulation by the useof nailable sarking clips. The nailable sarking clipsare driven into the upper surface of each rafter atonemetre intervals up the roof slope. The nailablesarking clips then support lengths of KingspanThermapitch TP10 zero ODP suitably trimmed tosize and placed between the rafters.

In cases where the insulation between rafters is to beflush with the bottom of the rafters but does not fill thefull rafter depth (Figures 1b, 1d, 2a, 2b, 3b, 3d, 4a& 4b), install the insulation with the aid of battensnailed to the side of the rafters. The battens should bein the appropriate position to ensure the insulation isflush with the bottom of the rafters.

SITEWORK

In cases where the insulation between rafters fully fillsthe rafter depth (Figures 1a ,1c, 3a & 3c), simplyinstall the correct thickness of insulation in such amanner that it is flush with the bottom of the rafters.

In all cases, ensure that insulation boards are tightlybutted and that there is a tight fit between theinsulation and the rafters. Fill all gaps with expandingurethane sealant.

UNDER RAFTER LAYER OF INSULATIONPlease refer to literature for Kingspan ThermawallTW56 zero ODP.

BREATHABLE SARKING MEMBRANEThe specified breathable sarking membrane(e.g. Kingspan nilvent TM) is applied as specified.Application advice should be sought from theappropriate membrane manufacturer.

SARKING FELTIn cases without a sarking board, the sarking felt isdraped over the rafters to provide a channel for waterdrainage and held in place by the slate/tile battens,which are nailed through the felt to the rafters.

In cases with a sarking board, the sarking felt isapplied over the sarking board and held in place bythe slates or counter battens which are nailed throughthe felt to the sarking board.

SLATING AND TILINGSlating and tiling over Kingspan Thermapitch TP10zero ODP is exactly the same as on any otherpitched roof except that in some instances the slate/tile battens are fixed to the previously appliedcounterbattens. It is, however, essential that slate ortiling rubble does not lay in contact with thebreathable sarking membrane (if used) as this mayallow wind driven rain or melted snow to penetratethe breathable sarking membrane.

SURFACE TREATMENTThe boards of Kingspan Thermapitch TP10 zeroODP have a foil faced durable surface and no furthertreatment is necessary. Kingspan Thermapitch TP10zero ODP is not intended to provide an internal finishand should be underlined with a suitable buildingboard.

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.
