Breathable Membrane is a 3-layer thermo-bonded product that consists of a PP non-woven fabric on the top and bottom layers for protection and reinforcement. It also includes a micro-porous PE film in the middle layer, which acts as a breathable membrane.
This breathable membrane is designed to be UV stable for up to three months, making it ideal for use in more moderate climates. For projects located in windier areas, our membrane with a higher tensile strength is recommended.
Additionally, we offer non-breathable membranes and waterproof breathable roof membranes. These products provide different benefits and functionalities depending on your specific needs. Lastly, consider checking out our breathable membrane from the Cromar brand, which is known for its quality and performance.
