As moisture can pass through the membrane it passes up and out of the building to help ventilate.
Waterproof breathable roof membrane.
Breathable roof membranes are installed on the cold side of the roof s insulation and beneath the batten.
Uv stable 4 months exposure clean easy to use.
Waterproof breathable membrane test tyvek roofing membranes tyvek s breathable roof membrane test examines 36 waterproof breathable membranes.
How do i choose a breather membrane.
Thanks to superior material durability and a unique functional layer the tyvek membrane beats all others.
No additional ventilation required.
Breathable membranes are often water resistant or waterproof and can therefore be used as a temporary covering.
There are breathable and non permeable membranes.
Breather roof membranes are water resistant but allow the movement of air through the membrane.
Lightweight waterproof flexible.
Its proven track record of exceptional moisture management high vapour permeability and durability makes it the superior protection solution for rainscreen cladding.
Non breathable membranes also known as non permeable membranes are entirely waterproof and wind tight.
Warm cold roof applications.
However it s recommended that the roof covering is installed as soon as possible.
Breathable roof membrane is the newer of the two underlays and the one whose popularity has soared in recent years.
Excellent tensile tear strength.
What are breathable roof membranes.
For use in tiled slated or metal roof systems.
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.
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.
Why breather membranes are required moisture often passes into the roof space as vapour and then condenses when it reaches a cool surface.
