Find out moreThis Thermafleece Breather Membrane is a lightweight and breathable underlay, specially designed for enhancing the integrity of your floors, walls and insulation. Manufactured to meet the stringent standards of EN 13859-1 for pitched roofing and EN 13859-2 for walls, it offers an exceptional combination of water resistance, breathability and ease of handling.
With its light-grey colour on one side and clean white on the other, this Thermafleece Breather Membrane is free from any text or images except for a subtle 150mm overlap line. Consisting of three distinct layers, including two outer layers crafted from non-woven polypropylene and an inner microporous film, this membrane ensures long-lasting protection and performance.
When it comes to installation, securing this membrane to your wall structure is easy. Begin at the bottom and work your way up, making sure to overlap the upper layers with the lower layers. Horizontal joints should have minimum overlaps of 100mm, while vertical lap joints should be at least 150mm. Be sure to avoid starting a vertical lap joint within 300mm of a corner for optimal results. Additionally, safeguard the bottom timber by providing a protective overlap.
To ensure a secure and permanent installation, fix this Thermafleece Breather Membrane at appropriate intervals using galvanised nails, stainless staples or similar fixing that guarantee long-lasting results.
