Breather Membranes
Breather membranes provide essential protection within roof and wall build-ups by allowing moisture vapour to escape while preventing water ingress. Suitable for use behind cladding and beneath roofing systems, they help support condensation control and protect the building envelope from weather exposure. We have a wide range available for you at our depot in Watford.

What is a breather membrane?
A breather membrane is a protective layer installed within roof and wall structures to prevent water penetration while allowing internal moisture vapour to escape. This helps reduce condensation risk and protects structural components from weather exposure.
Most common applications
- Pitched roof underlays
- Timber frame wall construction
- External wall cladding systems
- Sheathing protection layers
- Roof refurbishment projects
Why use breather membranes
- Helps control moisture and condensation
- Protects building fabric from weather ingress
- Allows vapour to escape from structures
- Supports long-term durability of construction systems
- Suitable for both roofing and wall applications

FAQ’s:
What does a breather membrane do?
It prevents water entering the building structure while allowing trapped moisture vapour to escape, helping reduce condensation risks.
Where are breather membranes installed?
They are typically installed behind cladding, beneath roof tiles, or within external wall systems to protect the building envelope.
Are breather membranes waterproof?
They are water-resistant rather than fully waterproof, meaning they block liquid water while remaining breathable to vapour.
Do modern roofs require breather membranes?
Most modern roof constructions include breather membranes to provide weather protection and support effective moisture management.
