Product Details
Housewrap breather membrane is a large roll of vapour-permeable material used to protect the walls of a building from wind and rain while allowing moisture from inside to escape. It is typically installed over the exterior sheathing or insulation before cladding or brickwork, helping to prevent damp and mould by letting trapped moisture evaporate. The membrane is lightweight, easy to cut, and can be fixed with staples, nails, or special tapes, with overlaps at joints to ensure a continuous barrier. Commonly called breather membrane or housewrap, it is essential in timber frame, masonry, and renovation projects for improving energy efficiency and wall durability. A 100m roll provides enough coverage for large sections of wall, making it suitable for both new builds and refurbishments.

Frequently Asked Questions
How much coverage does a 100m roll of housewrap breather membrane provide?
A 100m roll typically provides coverage for approximately 100-150 square metres of wall area, depending on the membrane width (usually 1-1.5m wide). You'll need to account for overlaps at joints which reduce the effective coverage by about 10-15%.
What's the difference between housewrap breather membrane and traditional roofing felt?
Housewrap breather membrane is vapour-permeable, allowing moisture to escape from inside the building while keeping rain out. Traditional roofing felt is impermeable and designed purely as a waterproof barrier, making it unsuitable for wall applications where breathability is essential.
Can I install housewrap breather membrane myself or do I need a professional?
Housewrap installation is suitable for competent DIYers with basic construction knowledge. The membrane can be fixed with staples, nails, or tapes, but proper overlapping and sealing at joints is crucial for effectiveness.
Is housewrap breather membrane suitable for both timber frame and masonry walls?
Yes, housewrap breather membrane is suitable for both timber frame construction and masonry walls. It's commonly used in new builds, renovations, and extensions to improve energy efficiency and prevent moisture problems in various wall types.
What tools do I need to install housewrap breather membrane?
You'll need a staple gun or hammer and galvanised nails, sharp knife or scissors for cutting, measuring tape, and specialist sealing tape for joints. Some installers also use a chalk line for marking straight installation lines.
