Frequently asked questions
What is a Breather Membrane?

A breather membrane, also known as a vapour-permeable membrane, is a type of building material used in construction primarily for its ability to allow moisture vapour to pass through while preventing liquid water from penetrating into the structure. It is typically installed on the external side of a building's insulation, beneath the external cladding or roofing materials. Breather membranes help to manage moisture within the building envelope, reducing the risk of condensation and mould growth while improving energy efficiency by allowing buildings to "breathe" and maintain a balanced internal environment.

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 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.
