Vapour barrier membrane
SAFETY ALU is a polymer bitumen membrane made with APP compound; thanks to the fibre glass carrier coupled with aluminium acts as a vapour barrier to prevent its passage and preventing it from damaging the insulating materials (vapour transmissibility µ=1.000.000).
APP: (Atactic - Poly - Propylene) polypropylene with irregular distribution of metal groups along the polymer chain. A polymer with this configuration is defined as "atactic".
Great resistance to UV rays
Great heat resistance
Good cold flexibility
