Vapour-insulation film ML

Vapour-insulation films ML 90 and ML 110 are three-layer films which are used to protect from vapour and dampness penetration in inclined and flat roofs and vertical wall constructions.

They are placed in parallel to or alongside the rafter, directly under thermal insulation. These films have intermediate resistance properties in comparison with MLS 98 and regular vapour-insulation films. ML vapour-insulation films fulfill the requirements of the European norm EN 13984:2006 and are marked with the CE symbol.
