What is a Breather Membrane?

Breather Membranes are designed to allow wall and roof structures to release excess moisture vapour into the atmosphere - to “breathe” - without allowing wind-driven rain and dust to penetrate wall or roof structures. They must be installed on the exterior (“cold”) side of any structure - beneath the main outer building lining, roof tiles or cladding.

It is advised to seal your Breather Membrane with corresponding Lap Tapes for a quality, breathable seal.

How do I Apply a Breather Membrane?

A breather membrane should be applied on the exterior side of any wall or roofing structure - under the outer building lining, roof tiles or cladding. It should be fixed at intervals with suitable, permanent fixings and finished with Breather Membrane Lap Tape for the most reliable and air-tight finish. It is best used in conjunction with a Vapour Control Layer applied to the interior of the structure.
