Klober reflective air barrier for exceptional vapour resistance

Klober Wallint® solar is a reflective air barrier and vapour control layer used on the warm side of insulation and rafters. It is ideal for application to ceilings and walls in warm roof construction and to ceilings below non-habitable lofts. The reflective surface greatly reduces heat loss while a vapour resistance of over 500 MNsg far exceeds the requirements of BS9250 (Code of Practice for design of ceiling airtightness in pitched roofs). As a result, Wallint solar is extremely effective in preventing water vapour from entering the roof space during the building’s drying-out period.
