It can be specified for lofts, although for larger contracts you may wish to specify Warmcel blown in by a specialist installer. For more information, please contact the manufacturers, Excel Industries Thermafleece has BBA approval, and can be specified for a wide range of contracts and applications. Please see the information below, and contact us for further information. THERMAFLEECE Technical specification and applications The low thermal conductivity of Thermafleece (0.039 W/m.K) compares favourably with that of other fibrous insulants. A range of three thicknesses is available (50mm, 75 mm and 100 mm), enabling any overall insulation depth to be achieved by combining different thicknesses. For example, 250 mm overall thickness provides a thermal resistance of R 6.35 (Km2/W). The table right shows thermal resistances provided by various thicknesses of Thermafleece. Thickness (+/- 5mm) (mm) Thermal Resistance (Km2/W) 50 1.25 75 1.90 100 2.55 150 3.80 200 5.10 250 6.35 Performance/Testing - International Standards Energy consumption in manufacture 14.6 Mj/jg or 136 MJ/m3 Thermal conductivity 0.039 W/m.K - ISO 8302 Water absorption (@ 100% RH) 40% Mould resistance 0 NORM B6010 Moth/bettle proofing Based on ISO 3998 Ignition point 560 C Spread of fire BS 5803-4 Technical service and back up In association with the manufacturers we can provide technical advice on how to incorporate Thermafleece into different forms of construction, for both refurbishment and new build projects. technical advice computer U-value and condensation risk analysis calculations site visits by technical staff copies of relevant reports and samples help and advice on meeting the requirements of Building Regulations (part L) Application Thermafleece should not be left exposed to sunlight or allowed to remain wet for extended periods. Store the insulant under cover and clear of the ground. Thermafleece is lightweight and easy to handle and install. It can be easily cut to shape and size with a sharp knife or guillotine. To retain the benefits of water vapour absorption and release, Thermafleece should be covered with a suitable breather membrane. Designers should consider specific project requirements and constraints before specifying breather membranes or other materials. Thermafleece in roofs Install Thermafleece between the rafters or ceiling joists, using sufficient to fit tightly without gaps. Alternatively, Thermafleece can be laid over the joists when the spaces between them are already filled and there is no risk of the material being compressed by foot traffic. Thermafleece should overlap the wall insulation to avoid thermal bridging at the eaves. Thermafleece in walls Push the Thermafleece into place between the studs. Fill all gaps between studwork, for example at trimmers around window openings. Thermafleece in suspended timber ground floors Drape a polythene netting or breather membrane over the joists and staple it in position on the top and sides of the joists to form a tray. Use the tray to support the specified thickness of Thermafleece level with the top of the joists. Thermafleece in intermediate timber floors The insulation can be supported on the plasterboard between pairs of joists. Simply push the batts into place.
