Vent 3 - Breathable Membrane
Breathable underlay for cold and warm roof applications in non-ventilated pitched roof systems.
Vent3 is a triple layer fabric,
high performance breather membrane made
from high tensile spun bonded polypropylene layers, around a micro-porous polypropylene film. Designed for used in a fully supported or unsupported tiled, slated or metal roof system. Superior moisture vapour permeability is achieved whilst maintaining the highest levels of water resistance. Vent3 has a printed dark blue upper surface and white under-face.
The higher vapour permeability
and waterproof nature of the membrane,
combined with excellent tensile/tear strength, make Vent3 an ideal product for use in both warm and cold roof applications. Vent3 is equally suitable whether draped unsupported over rafters or laid directly over insulation. It will allow the escape of eater vapour from within the roof structure whilst protecting against wind driven rain, snow and dust which may penetrate the main roof waterproofing, providing a permanent quality breather underlay, which will last the life of the roof construction.
