Breather Membranes for the Best Roofing Protective Layer

Breather membranes are designed to sit between the outer layer of insulation and underneath your roof, creating a moisture-free and breathable barrier for your home. Made from durable materials, your roof will stay waterproof during the toughest of conditions; whether heavy rain or treacherous winds. They are simple to install, so whether you are a DIY enthusiast or a professional roofer, it will work for you.

All of our breather membranes are fully approved by organisations including BBA, IAB, and UKAS.

What are the benefits of a breather membrane?

Breather membranes are used in construction to control the movement of air and water vapour and protect the building from rainfall and wind. There are many benefits to using a breather membrane including:

• Improved air tightness resulting in better indoor air quality.
• Protection from moisture, preventing unseen growth of mould and mildew during the building’s construction.
• Easy to install as they are lightweight, flexible and can be cut to size seamlessly.
• Widely versatile as they can be used on roofs, walls and flooring.

Breather membranes are the go-to material if you need to improve air tightness. If you need a membrane that offers total water vapour resistance, check out our range of vapour control layers which include ELOTENE Vapour Barrier and ALUTRIX Self Adhesive Vapour Barrier.
