OMEGA DRAINY PLUS Roofing Underlay Membrane

Description

The OMEGA DRAINY PLUS roofing underlay is designed for maximum vapour diffusion, while offering high-quality protection for ventilated pitched roofs, particularly those covered with sheet metal. Thanks to its three-dimensional polypropylene mesh, it ensures ventilation beneath the covering and protects against the effects of heat and damage caused by sheet metal. Main features: Sd value: 0.02 m, ensuring efficient vapour diffusion. Advantages: Specially designed for sheet metal roofs. Waterproof and windproof. UV stable and recyclable. Non-slip and anti-glare. Applications: Ventilated pitched roofs. Direct installation on roof boarding. Technical performance: Longitudinal extension (EN 12311-1): 50 - 60 %. Transverse extension (EN 12311-1): 50 - 60 %. Longitudinal tensile strength (EN 12311-1): 295 (± 40) N/50 mm. Transverse tensile strength (EN 12311-1): 205 (± 40) N/50 mm. Longitudinal tear resistance (EN 12310-1): 185 (± 30) N. Transverse tear resistance (EN 12310-1): 230 (± 30) N. Thickness: 0.75 mm (with three-dimensional mesh: 7.5 mm). Weight: 450 g/m² (± 5 %). Temperature resistance: -20 to 100 °C. UV resistance: 3 months. Reaction to fire class (EN 13501-1): E.
