Sepa solar is Klober’s new reflective air barrier and vapour control layer. With a vapour resistance of over 500 MNsg, it far exceeds the requirements set out in BS9250 (Code of Practice for design of the airtightness of ceilings in pitched roofs). Its reflective surface reduces heat loss through the roof. Moreover, when combined with other products in Klober’s airtightness range it will help you minimise energy loss. Features Use in conjunction with Klober’s other airtightness products to minimise energy loss. As even thicker layers of insulation are installed to comply with more demanding Building Regulations, so it becomes increasingly important to provide an air barrier and vapour control layer on the warm side of the insulation. Reflective surface increases construction’s thermal resistance when facing into the services void or room. Vapour resistance of >500 MNsg, far exceeding requirements of BS9250. Prevents large volumes of watervapour entering a construction from the interior, particularly during the drying-out period. Provides support for insulation boards or quilts. Application The inner face of an insulated roof. Walls (incl timber frame) & cold and warm roof applications. Ceilings & walls of rooms-in-theroof, and on the ceilings below nonhabitable lofts. Properties Material: Composite woven, non-woven, foil. Colour: outside - silver. Roll weight: 13.5kg. Certification: CE certified.
