Products / IKO Armourvent Base

Partially adhered self-adhering SBS modified bitumen base sheet on a non-woven glass fiber mat, with a patterned underside of discontinuous bituminous strips that lets moisture vapour diffuse beneath the membrane. The top has a self-adhering selvage lap and a micro-perforated film for a heat welded cap sheet. The data sheet lists 2.8 mm (110 mils) in 1,000 mm x 12 m rolls. It is designed to limit blistering from trapped moisture.
