IKO Armourvent Base, 1Mx12M Roll
$111.31 / ROLL
Armourvent Base is a SBS modified bituminous base sheet that is specially designed for partial adhesion to the roof substrate. A unique pattern of discontinuous modified bituminous strips provides for easy installation, stress distribution from substrate movements, and primarily aids venting (vapour diffusion) of any moisture below the membrane. Thus, the product minimizes roofing system blisters that may form due to un-vented moisture build-up. The top surface is finished with a micro-perforated poly-film to allow heat welding application of the cap sheet, and also includes a self adhesive selvage lap.
