Klober reflective air barrier for exceptional vapour resistance

Among Klober’s specialist airtightness products, Wallint® solar is a reflective air barrier and vapour control layer which is used on the warm side of insulation and rafters.

Ideal for energy-efficient construction projects, it can be applied either to ceilings and walls of rooms in the roof or to ceilings below non-habitable lofts.

With a vapour resistance of over 500 MNsg this is way above the requirement of BS9250 (Code of Practice for design of ceiling airtightness in pitched roofs). It is the best performing product in its class for preventing water vapour entering the roof space during a building’s drying-out period and offers the added benefit of a reflective surface to reduce heat loss.
