Waterproof Breathable Roof Membrane

Waterproof high performance triple layer breathable membrane.

Waterproof breathable roof membrane.

Uv stable 4 months exposure clean easy to use. Breathable roof membranes are installed on the cold side of the roof s insulation and beneath the batten. However it s recommended that the roof covering is installed as soon as possible. Why breather membranes are required moisture often passes into the roof space as vapour and then condenses when it reaches a cool surface.

Waterproof breathable membrane test tyvek roofing membranes tyvek s breathable roof membrane test examines 36 waterproof breathable membranes. Lightweight waterproof flexible. No additional ventilation required. Breathable membranes are often water resistant or waterproof and can therefore be used as a temporary covering.

They don t allow condensation to pass through the roof structure so they re installed on the warm side of the insulation to keep the insulation dry and. As moisture can pass through the membrane it passes up and out of the building to help ventilate. Dupont tyvek uv facade is the next generation in lightweight advanced protective membranes. Its proven track record of exceptional moisture management high vapour permeability and durability makes it the superior protection solution for rainscreen cladding.

There are breathable and non permeable membranes. Warm cold roof applications. Non breathable membranes also known as non permeable membranes are entirely waterproof and wind tight. What are breathable roof membranes.

Breathable roof membrane is the newer of the two underlays and the one whose popularity has soared in recent years. Breathable membranes or breather membranes have been designed to improve ventilation and reduce condensation build up within the roof space as well as ensuring insulation remains effective. Breather roof membranes are water resistant but allow the movement of air through the membrane. For use in tiled slated or metal roof systems.

Breathable membrane low resistance and non breathable membrane high resistance are modern lightweight underlay alternatives to the traditional bituminous type 1f products of yore. Thanks to superior material durability and a unique functional layer the tyvek membrane beats all others.
