OMEGA LIGHT Roofing Underlay Membrane

Description

The OMEGA LIGHT roofing underlay membrane is a highly vapor-permeable (HPV) membrane designed for direct installation on insulation or timber sarking boards. Its three-layer non-woven structure ensures excellent water vapor diffusion while offering optimal protection against rain and wind. Thanks to its two acrylic adhesive strips, it ensures fast and efficient installation for pitched roofs and ventilated facades. Main characteristics: Sd value: 0.025 (+ 0.035 / - 0.01) m, promoting optimal water vapor diffusion. Advantages: Watertight against rain and wind. UV stable and fully recyclable. Non-slip, easy to cut and anti-glare. Applications: Ventilated pitched roofs. Closed and ventilated cladding. Certifications: Watertightness test carried out by Holzforschung Austria (Order No.: 301/2003/1-T/HH). Technical performance: Longitudinal extension (EN 12311-1): 40 - 110 %. Transverse extension (EN 12311-1): 60 - 120 %. Longitudinal tensile strength (EN 12311-1): 305 (±40) N/50 mm. Transverse tensile strength (EN 12311-1): 225 (±20) N/50 mm. Longitudinal tear resistance (EN 12310-1): 170 (-17/+30) N. Transverse tear resistance (EN 12310-1): 230 (±50) N. Thickness: 0.6 mm. Weight: 145 g/m² (±5). Temperature resistance: -40 to 80 °C (briefly up to 100 °C). Fire reaction class (EN 13501-1): E.
