Breathable House Wrap Membrane Roofing Waterproofing Membrane
breathable membrane, which has good water resistance and vapor breathability, e.g., prevents moisture from entering the buildings, while permits water vapor exit the building. And the breathable membrane can thus improve building durability by protecting wall sheathing and framing from moisture.
One key point : Breathable Waterproofing Membrane for Timber Frame helps reduce homeowner energy bill because homes stay cool in the summer and warm in the winter and dry all year round.
How does Breathable House Wrap Membrane Roofing Waterproofing Membrane works?
breathable membrane is made by two layers of non-woven fabrics and one layer of microporous polymeric membrane in the middle.
1. It has superior air resistance that helps to protect insulation from drafts, reducing energy costs.
2. It provides water resistance that helps to prevent water from entering walls, avoiding costly damage.
3. It allows moisture vapor to escape while protecting against air and bulk water instrusion.
4. It has excellent tear strength and allows 120days of UV exposure.
