Product Description

An economy breathable roof underlay for cold and warm roof applications which give major benefits over traditional roof underlays.

Vent 3 Light is a triple layer, high performance breathable membrane, made from two high tensile spun bonded polypropylene layers, thermally calendared to a micro porous polypropylene film. Designed for use in fully supported or unsupported tiled, slated or metal roof systems. Vent 3 Light has full moisture vapour permeability, whilst maintaining the highest levels of water resistance. Vent 3 Light has a printed grey upper surface and plain grey underface.

The high vapour permeability and waterproof nature of the membrane, combined with excellent tensile/tear strength, makes Vent 3 Light an ideal product for use in both warm and Cold roof applications.

Vent 3 Light is equally suitable whether draped unsupported over rafters or laid directly over insulation. It will allow the escape of water 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.

Please note this product requires no ventilation.
