Wind Barriers

- also called housewrap, to contribute to efficient insulation
Walki wind barrier or house wrap solutions are complementary to the roofing underlay and part of the building envelop that efficiently contribute to the building energy saving thanks to its excellent resistance to water penetration, while ensuring appropriate vapor breathability in every situation.

Walki®Wall Breath Walki®Wall Breath is a watertight, vapour-open membrane designed to be used as a wind protection underlay behind the outer wall construction. The membrane can withstand temperatures of up to 80°C, making it suitable for most wall structures. Walki® Wall Facade Walki®Wall Facade is a premium membrane which is watertight, vapour-open and designed to be used as a wind protection underlay behind the outer wall construction (closed or open cladding). The membrane can withstand temperatures of up to 100°C, and is UV resistant (5000h UV) making it suitable for most wall structures that needs to be exposed to weather conditions up to 6 months. Walki®Wall Film Perforated Walki® Wall Film Perforated is designed to address a good compromise between performance and costs as it develops a W2 resistance to water penetration with high strength resistance, which is very effective to prevent moisture and water to enter the building, while allowing moisture to flow from inside to outside. Walki®Wall Film Reflex Perforated Walki® Wall Film Reflex Perforated is designed to address a good compromise between performance and costs as it develops a W2 resistance to water penetration with high strength resistance, which is very effective to prevent moisture and water to enter the building, while allowing moisture to flow from inside to outside. In addition, the reflective surface contribute to global insulation by increasing heat reflection.
