CLASSIC VAPOUR BARRIER
It protects the roof’s thermal insulation layer against water vapour coming from inside the building. Thanks to the high sd coefficient, it is an excellent barrier against moisture on the roof surface. It is also an excellent insulation against harmful hydromigration between partition walls in skeletal structures buildings.
PROTECTION AGAINST MOISTURE
Thanks to the use of polyethylene, which is characterized by low water vapour permeability, the film effectively protects the structure of walls and roofs from moisture.
RESISTANT TO MECHANICAL DAMAGE
The multilayer structure ensures increased mechanical strength within reduced thickness.

MOUNTING & FASTENING
Subsequent strips of foil shall be mounted on the overlap, the size of which depends on the direction of laying – 15 cm for parallel laying and 20 cm for perpendicular laying to the rafters. The foil should be attached to the rafters with staples, and the overlapping strands should be tightly connected using double-sided Foliarex tape.
