They are simple to install, so whether you are a DIY enthusiast or a professional roofer, it will work for you.

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.

They are used as roof membranes to regulate temperature and moisture levels within the roof, preventing condensation and promoting the longevity of the roof.

They are installed under the roof covering and should be securely fastened to the roof structure using appropriate fixings to ensure proper protection. Please consult the manufacturer's instructions for specific installation guidelines.

As lightweight membranes, they are suitable for various roof types, including pitched roofs and flat roofs. Choose the right product for your roof type based on the manufacturer's recommendations.

Selecting the right membrane for your building project will depend on what you require. Breathable roofing membranes are designed to let the building "breathe" and allow movement through the membrane to ensure water can leave the roof. Alternatively, if you require a completely water-resistant membrane, vapour control layers are often the route to go as they prevent any moisture from entering the roof.
