Breathable underlay for
cold and warm roof applications in non-ventilated
picthed 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.
