STROTEX AKTIV PP

STROTEX ACTIVE PP is a four-layer roofing membrane for universal use thanks to its outer aluminium layer, which gives higher resistance to UV radiation and protects against heat loss (up to 25% more than a standard membrane). With their innovative technology, Strotex Q membranes equalise differences in water-vapour concentration and so protect the roof's thermal-insulation layer. It protects the thermal insulation from rain and snow from the outside. Every layer of the product contains UV stabilisers that slow down weather-induced ageing. High vapour permeability lets the membrane absorb moisture and carry it away through the ventilation layer. It is fully waterproof, allows the thermal insulation to fill the full rafter depth and serves as a wind barrier, while the metallic top layer improves heat reflection.
