Suitable for wall applications, and use on timber frame and offsite/ modular constructions.
Description
A high quality, four-layer laminate, class W1 water-resistant wall breather membrane, for insulated wall applications.
To maximize the products performance the reflective face is unbranded, with no text or images, and is white on the reverse.
Features and benefits:
- Four-layer laminate, wall breather with microporous core.
- 98% reflectivity, which can achieve an additional R-value of up to 0.74 m²K/W.
- Class W1 water resistance to EN 1928.
- CE compliant to EN 13859-2 (walls).
- Reflective face allows cooler in summer and warmer in winter.
- Airtight, and highly vapour permeable.
- Fire classification E to EN 13501-1.
