The unique composition of the product effectively deals with all forms of energy transfer. Thermally tested achieving a high thermal resistance of up to 2.07m²K/W for ThermaQuilt accompanied by a 38mm air cavity either side of the material. ThermaQuilt has been independently tested and certified to the latest Industry Standards, including BDA Kiwa certificate of Agreement. Application Installation of ThermaQuilt for pitched roof applications and additional insulation products should be in accordance with the manufacturers certificate, fixing instructions and current good building practice.
