Design Considerations

4 General4.1 Thermo-Foil ES/Thermo-Brite III, Thermo-Foil and Eco-Brite and Tape provide thermal resistance of adjacent airspace in new or existing dwellings and buildings of similar occupancy, type and condition. Additional insulation will be required in order to meet the thermal requirements of the national Building Regulations.

4.2 The use of the products does not in itself promote infestation and there is no food value in the materials used. The creation of voids within the structure, ie gaps between the lining and the sheet, may provide habitation for insects or vermin in areas already infested and such infestation may be difficult to eradicate.

4.3 Plasterboard used in conjunction with the products must comply with BS EN 520 : 2004 and be installed in accordance with BS 8212 : 1995.

4.4 Penetration of the products by services should be kept to a minimum and sealed to limit water vapour penetration.

Masonry and timber frame walls4.5 The wall or sub-frame must be structurally sound, designed and constructed in accordance with the following standards.

Masonry• BS EN 1996-1-1 : 2005• BS EN 1996-2 : 2006.

Timber• BS EN 1995-1-1 : 2004• BS EN 351-1 : 1996.

4.6 Existing walls must be in a good state of repair with no evidence of rain penetration, damp or frost damage.

Pitched roof4.7 The products are for use in constructions where the ceiling follows the pitch of the roof and encloses a habitable space. They are fitted above the rafters and must be installed in accordance with BS 5250 : 2011 and the Certificate holder’s instructions.

4.8 Roofs must be constructed and tiled or slated in accordance with the BS 5534 : 2003.

4.9 Due to the reflective finish on the products, distortion of television reception may occur when using an aerial in the roof space. External aerials will not be affected.

4.10 The products can also be used underneath existing insulation in a metal roof construction, in accordance with BS 5427-1 : 1996.

Ceilings — lofts4.11 In lofts the products can be used at ceiling level below joists providing thermal resistance to the structure and also preventing water vapour from entering.

Floors4.12 The products are suitable for use with ground supported, suspended, exposed and semi-exposed concrete and timber floors, suspended ground floors must include suitable ventilation or a dpm.

4.13 The floor finish should be installed in accordance with EN 12871 : 2010.

5 Practicability of installationThe products are designed to be installed by a competent general builder, or a contractor, experienced with these types of products.

6 Thermal performance6.1 Calculations of thermal transmittance (U value) should be carried out in accordance with BS EN ISO 6946 : 2007 and BRE Report BR 443 : 2006 using the following values for the outer foil of the products Thermo-Foil ES/Thermo-Brite III, Thermo-Foil, Eco-Brite and Tape:

• 0.05 outer surface emissivity of the products• 0.45(1)(2) m2·K·W–1 R value of an air cavity adjacent to the products 13 mm thick (upward heat flow)• 0.66(1)(2) m2·K·W–1 R value of an air cavity adjacent to the products 20 mm thick (horizontal heat flow)• 1.33(1)(2) m2·K·W–1 R value of an air cavity of 50 mm thick, adjacent to the products (downwards heat flow)(1) Unventilated cavity with a width and length at least 10 times the thickness and one high emissivity surface.

7 Risk of condensationInterstitial condensation

7.1 Roofs (with the products at joist level and/or above rafter level), walls and floors incorporating the products, depending on constructions can adequately limit the risk of interstitial condensation when designed and constructed in accordance with BS 5250 : 2011, Annexes D and F to H.

7.2 Consideration must be taken in the overall installation to minimise perforations by services. Joints at wall/ceiling and wall/floor level must be well sealed to offer significant resistance to water vapour transmission.

7.3 As with other types of insulation applied to the inside of a wall, there may be a risk of cold bridging from the floors or ceilings, particularly in concrete slab construction.

7.4 When the products are used in conjunction with sarking boards (insulating or otherwise) an appropriate ventilation gap between the underlay and the sarking boards must be maintained.

Surface condensation7.5 Roofs (with the products at joist level and/or above rafter level), walls and floors can adequately limit the risk of surface condensation when the thermal transmittance (U value) does not exceed 0.35 W·m–2·K–1 (roofs) or 0.7 W·m–2·K–1 (walls or floors) at any point and the junctions with walls are designed in accordance with

section 6.3 of this Certificate.

7.6 Roofs (with the products at joist level and/or above rafter level), walls and floors can adequately limit the risk of surface condensation when the thermal transmittance (U value) does not exceed 1.2 W·m–2·K–1 at any point and designed in accordance to BS 5250 : 2011, Annexes F to H. Further guidance may be obtained

from BRE Report BR 262 : 2002.
