Vapour control foil made from LDPE that effectively prevents the transfer of water vapour from the interior of the building to the thermal insulation. The material is characterised by increased resistance to adverse weather conditions such as snow, rain and dust.

The Supervap Premium vapour barrier is primarily used as an insulating layer that controls vapour levels in wall, floor, roof and ceiling constructions. The product is also recommended for use as insulation and acoustic protection in floor finishes, such as under floor panels.
