cost effective, trussing and sub roof membrane

DUO extra roofing membrane

3-layer, vapour-permeable sheathing membrane with microporous film and woven grid
Can be used in ventilated and unventilated roof assemblies as a trussing, sub-roof or sheathing membrane
Can be used as a sub-roof glued to sheathing or a dimensionally stable underlay
Two vertically aligned, integrated self-adhesive strips ensure economical and lasting adhesion of longitudinal seams
