8 Points ofattention forthe specifier

1 The product is delivered in rolls packed in a protective sealed bag and should include product name, dimensions,the BDA identification mark and the number of this Certificate.

2 Roof insulation- special attention should be given to the air tightness of the ceiling, being the most important measure toavoid excessive condensation in the space above the insulation; if ventilation has been provided above theSuperQuilt layer, there is no requirement for a vapour control layer above the (plasterboard) ceiling, providedthat the SuperQuilt layer is thoroughly sealed at all joints, resulting in an airtight layer;

- the building physical behaviour of roof structures incorporating the insulation must be analyzed by a specialist;The specialist can be either a qualified employee of the specifier or a qualified consultant or a qualifiedemployee of the certificate holder. He will check the building physical behaviour of the designed roofconstruction and if need be, advice about improvement to achieve final specification;

- if ventilation openings are used they should be positioned along two opposite sides of the roof at eaves levelin accordance with BS 52503;

- ventilation openings should be arranged in such a way that blockage is prevented and also the ingress of rain,snow, birds and small mammals.

3 Thermal performance aspects- for the purpose of U-value calculations to determine if the requirements of the Building (or other statutory)Regulations are met, the thermal resistance of the product in combination with a non-ventilated air cavity onboth sides of the SuperQuilt layer of 25 mm (nominal value) is to be calculated according to BS EN ISO 69464

and/or BR4435, the thermal bridging effect has to be assessed according to BBA Information BulletinNo. 3: Reflective foil insulation – Conventions for U-value calculations, March 201010;

- to minimize the effect of thermal bridging cross-battening is advised;- the requirement for limiting the heat loss through the building fabric, including the effect of thermal bridgingcan be satisfied if the U-values of the building elements do not exceed the maximum values in the relevantElemental Methods given in the National Building Regulations of England and Wales (Approved Documents L),Scotland (Technical Standards Regulations 9) and Northern Ireland (Technical Booklet F); further informationon regulations is given in section 11 of this Certificate.

4 Condensation risk- roofs incorporating the product will adequately limit the risk of interstitial condensation when designed inaccordance with BS 52503;

- roofs with insulation at rafter level should be ventilated along the eaves and the ridge in accordance withBS 52503;

- when installed in accordance with this Certificate the product will provide a convectionfree envelope of highvapour resistance;

- when installed against the external side of the rafters or battens a vapour control layer is required, unless aspecialist advises otherwise (see section 8.2);

- when installed against the internal side of the rafters or battens the product will perform as a vapour barrierand should be used in conjunction with a suitable breather membrane against the sheathing on the externalside of the studs or battens, see also section 10.

5 Behaviour in relation to fire- when installed with an internal lining board, e.g. 12.5 mm thick plasterboard, the insulation will be containedbetween the external part of the roof and internal lining board, until one is destroyed. Therefore, the insulationwill not contribute to the development stages of a fire or present a smoke or toxic hazard;

- the insulation must not be carried over junctions between roofs and roofs required to provide a minimumperiod of fire resistance;

- the continuity of fire resistance must be maintained, for example as described in: England and Wales-Approved Document B, Volume 1, Sections 5.11 to 5.12;Scotland-Mandatory Standard 2.2, clause 2.2.10; Northern Ireland-Technical Booklet E, paragraph 3.21;

- the use of the product will not affect the fire rating obtained by tiled or slated roofs when evaluated byassessment or test to BS 476-3:2004.

6 DurabilityThe product is stable, rot-proof and durable and will remain effective as an insulant for the life of the building inwhich it is installed. There is no risk for moth or beetle infestation.

Performance factors in relation to the Major Points of Assessment

2.1.7 Thermal insulation propertiesThe Product is effective in reducing the thermal transmittance (U-value) of flat timber roofs and helps to reduce energy transfer by conduction, convection andradiation, and it reflects infra-red radiation. The Product acts by creating a low emissivity air space in the roof, thus reflecting heat back into the building. TheProduct is effective in winter by reflecting heat back into the building and cold out, and in summer the Product is an effective barrier to solar over-heating. TheProduct is most effective with a minimum 25 mm air gap on either side, battens can be used to create this gap.

The requirement for limiting heat loss through the building fabric, including the effect of thermal bridging can be satisfied if the thermal transmittance (U-value) ofthe roof incorporating the Product does not exceed the maximum and target U-values in the Elemental Methods given in the national Building Regulations.


For the purpose of U-value calculations the thermal resistance and U-value of flat roofs incorporating the Product (in combination with a minimum 25mm aircavity on both sides of the Product layer) should be calculated according to BS EN ISO 10211.

Due consideration should be given to BS EN ISO 6946, BS EN ISO 10456 and BRE Report 443, using the declared thermal resistance or conductivity (λD) valueof the Product.

Additional insulation in the roof void is required to meet the U-value requirements of the national Building Regulations.

Thermal bridging at junctions and around openingsThe overall design and construction of junctions with other elements and openings should minimise thermal bridges and air infiltration.

Guidance on linear thermal transmittance, heat flows and surface temperatures can be found in the documents supporting the national Building Regulations andBS EN ISO 10211, BRE Information Paper IP1/06, BRE Report 262 and BRE Report 497. To minimise the effect of thermal bridging cross-battening is advised.Account should be taken of Government Accredited Construction Details for Part L - Timber Frame Illustrations in England and Wales and AccreditedConstruction Details for Scotland.

2.1.8 Adequacy of fixingThe Product can be installed sufficiently taught in flat timber roofs, when using the correct fixings and correct distances between fixings to maintain its thermalinsulation benefit.

Interstitial condensationFlat timber roofs incorporating the Product can adequately limit interstitial condensation when they are designed and constructed in accordance with BS 5250and BRE Report 262.

Any openings or penetrations in the ceiling and the ceiling-wall joints must be well sealed. Special attention should be given to the air tightness of the ceiling toavoid excessive condensation in the space above the Product and additional insulation. If ventilation has been provided there is no requirement for a VCL abovethe ceiling, provided that the Product is thoroughly sealed at all joints with YBS Foil Tape (resulting in an airtight layer).

Ventilation to the air space should be in accordance with BS 5250. The water vapour resistance of any additional insulation material should also be taken intoconsideration.

Surface condensationFlat timber roofs incorporating the Product can adequately limit surface condensation on internal ceilings when the thermal transmittance (U-value) does notexceed the maximum values given in the national Building Regulations at any point, including junctions with walls and openings when designed in accordancewith BS 5250 and BRE Report 262.

2.1.11 Water vapour transmission resistanceWhen all joints are sealed using YBS Foil Tape, the Product has a high water vapour transmission resistance in accordance with BS EN 1931, BS EN 12086and BS EN ISO 12572 and can act as a VCL. The Product can adequately resist the passage of water vapour to the underlying structure and when installedagainst the internal side of the roof joists or battens the Product will perform as a vapour barrier.

2.1.12 Resistance to precipitation including wind-driven rainThe Product is protected by the roof covering to prevent rain water ingress across the roof void to the face of the Product. Design of joints through a roof shouldbe in accordance with BS 6093.

The Product has adequate water-tightness in accordance with BS EN 1928.

2.1.13 Water absorptionThe foam layers within the Product are sealed, stopping water from penetrating the air pockets whilst in-situ in the application. The Product does not absorbwater over the long-term in accordance with BS EN 12087 and BS EN 12088.

2.1.14 Behaviour in relation to fireThe Product is classified as Euroclass E in accordance with BS EN 13501-1.

The Product has a low rate of heat release and a low rate of fire growth when ignited.

When installed with additional insulation materials, the fire properties of the additional insulation materials must be taken into account.

Combustible materials are permitted in the roof void but require any opening or penetration to be sealed.


Care should be taken to avoid accidental ignition during maintenance works (e.g. by a roofer’s or plumber’s torch).

When suitably encapsulated in a roof void, the Product will not contribute to the development stages of a fire or present a smoke or toxic hazard.

Junctions between the roof and compartment walls must be fire stopped. The Product must not be carried over junctions between roofs and walls required toprovide a minimum period of fire resistance. The continuity of fire resistance (by compartmentalisation) must be maintained in accordance with the provisions ofthe national Building Regulations.

Proximity of flues and appliancesThe installed Product must be separated from any chimney or heat-producing appliance or an incinerator flue pipe passing through the roof, by a separation.The separations recommended are detailed in the Approved Documents to the national Building Regulations.

7 Annualverificationprocedure

8 Points ofattention forthe specifier

In order to demonstrate that the FPC is in conformity with the requirements of the technical specification described in thisCertificate the continuous surveillance, assessment and approval of the FPC will be done in a frequency of not less than1 time per year by Kiwa Ltd. For the purpose of the annual assessment a sample of the product (1 roll) will be independentlytaken at the production site. The annual assessment will concern the following product characteristics, which will bedetermined and assessed by BDA and Kiwa Ltd.:

• Thickness BS EN 823:1995• Width BS EN 1848-2:2001• Length BS EN 1848-2:2001• Mass BS EN 1602:1997• Thermal resistance of core BS EN 16012:2012, method B (BS EN 12667: 2001)• Hemispherical emissivity of foil faces BS EN 16012:2012, Annex D

Remark: If at the time of the verification testing a new version of a mentioned Test Standard has been issued, the newerversion shall prevail

1 The product is delivered in rolls packed in a protective sealed bag and should include product name, dimensions,the BDA identification mark and the number of this Certificate.

2 Wall insulation- special attention should be given to the air tightness of the internal lining, being the most important measure toavoid excessive condensation in the space behind the insulation; if ventilation has been provided in the externalcavity, there is no requirement for a vapour control layer behind the internal lining, provided that the SuperQuiltlayer is thoroughly sealed at all joints, resulting in an airtight layer;

- the building physical behaviour of wall constructions incorporating the insulation must be analysed by a specialist;the specialist can be either a qualified employee of the specifier, a qualified consultant or qualified employee of theCertificate holder. The qualified person will check the building physical behaviour of the designed wall constructionand if need be, advice about improvement to achieve final specification;

- if ventilation openings (not greater than allowed for a ‘non-ventilated air cavity’ according BS EN ISO 6946) areused they should be positioned at the top and bottom of the external lining in accordance with BS 52504;

- ventilation openings should be arranged in such a way that blockage is prevented and also the ingress of rain, snow,birds and small mammals.

3 Thermal performance aspects- for the purpose of U-value calculations to determine if the requirements of the Building (or other statutory)Regulations are met, the thermal resistance of the product in combination with a non-ventilated air cavity on bothsides of the SuperQuilt layer of nominal 20 mm or 13 mm (to be achieved as shown in Figures 1, 2, 3 and 4 insection 9 of this Certificate) is to be calculated according to BS EN ISO 69465 and/or BR4436, the thermalbridging effect has to be assessed according to BBA Information Bulletin No. 311;

- the requirement for limiting the heat loss through the building fabric, including the effect of thermal bridging canbe satisfied if the U-values of the building elements do not exceed the maximum values in the relevant ElementalMethods given in the National Building Regulations of England and Wales (Approved Documents L), Scotland(Technical Standards Regulations 9) and Northern Ireland (Technical Booklet F); further information on regulationsis given in section 11 of this Certificate.

4 Condensation risk- walls incorporating the product will adequately limit the risk of interstitial condensation when designed inaccordance with BS 52504;

- when installed in accordance with section 10 of this BDA Agrément® the product will provide a convection-freeenvelope of high vapour resistance;

- when installed against the external side of the studs or battens a vapour control layer is required, unless a specialistadvises otherwise (see section 8.2);

- when installed against the internal side of the studs or battens the product will perform as a vapour barrier andshould be used in conjunction with a suitable breather membrane against the sheathing on the external side of thestuds or battens, see also section 10.

5 Behaviour in relation to fire- the product does not prejudice the fire-resistance properties of the wall. Therefore, the insulation will not contributeto the development stages of a fire or present a smoke or toxic hazard;

- when properly installed, the product will not add significantly to any existing fire hazard;- the product will be contained within the wall by the overlay until the overlay itself is destroyed. Therefore, theproducts will not contribute to the development stages of a fire or present a smoke or toxic hazard;

- the continuity of fire resistance must be maintained, for example as described in: England and Wales- ApprovedDocument B, Volume 1, Sections 5.11 to 5.12; Scotland-Mandatory Standard 2.2, clause 2.2.10; NorthernIreland-Technical Booklet E, paragraph 3.21;

- the use of the product will not affect the fire rating obtained by brick or block walls when evaluated by assessmentor test to BS 476-3:2004.

6 DurabilityThe product is stable, rot-proof and durable and will remain effective as an insulant for the life of the building in whichit is installed. There is no risk for moth or beetle infestation.
