EWL is a single bank extruded weather louvre, providing high performance rain defence. Suitable for applications requiring screening and ventilation. EWL is a single bank louvre system with comparable performance to a double bank louvre, achieving Class A up to 3 m/s. See for performance details. Highly aerodynamically efficient – this reduces air resistance, allowing the plant and the aperture to be minimised thereby saving running costs. Durable and maintenance free – UL is completely made from corrosion resistant materials. Thermal expansion of the louvres enabled – the louvres are clipped (and not riveted or screwed) to structural supporting mullions. Proven performance - EWL has been tested to EN 13030:2001. Easy to install – EWL can either be delivered to site pre-assembled or as a kit of parts. 50mm pitch Colt EWL Extruded Weather Louvre is a versatile louvre system providing either screening and/or rain defence. Louvre blades form an aerodynamically efficient profile to achieve a high degree of rain defence. Allowance is made for thermal expansion without distortion along the length of each louvre blade. Water drains efficiently onto the cill through the mullions. Static louvre Extruded blades: Aluminium 6063-H T5 All other components: Aluminium 3005 H14 50mm pitch at 45°
