Eurovent 150g/m² Breathable Roof & Wall Membrane (1m x 50m Roll)

Engineered for peak thermal performance and moisture control, the Eurovent 150g/m² Breathable Membrane delivers professional-grade protection for warm and cold pitched roofs, as well as timber frame wall constructions. Manufactured by Eurosystem Polska, this 3-layer vapor-permeable underlayment acts as a high-strength weather barrier that allows internal condensation to escape while keeping wind-driven rain and snow completely out.

Built with a high 6800 mm, water-column resistance (Class W1) and enhanced 4-month UV stability, it provides outstanding durability during extended construction site delays. Its balanced 150 g/m² mass offers an ideal compromise between light handling and heavy-duty tear resistance.

Key Features & Benefits

• Superior Water Tightness: Class W1 resistance withstands up to 6800 mm $\text{H}_2\text{O}$ water column to protect timber framing and insulation during construction.

• High Breathability: Vapour permeability of ca. 3000 g/m²/24h reduces internal condensation and risk of rot.

• 4-Month Extended UV Stabilization: Withstands direct solar exposure for up to 12 weeks during installation delays.

• 3-Layer Composite Build: High tear strength and flexibility down to -40°C ensure easy handling without cracking.
