Colt 3UL Universal Louvre is a roll-formed triple bank louvre system designed for applications requiring ventilation with the maximum degree of rain defence. When high level rain defence is needed, we recommend the use of either 2UL or 3UL. When rain defence is not of primary importance, we recommend the use of 1UL. Highly aerodynamically efficient – this reduces air resistance, allowing the plant and the aperture to be minimised thereby saving running costs. Enhanced rain defence performance - 2UL and 3UL versions have high resistance to rain ingress. Unlike other louvre types, Colt 2UL and 3UL panels have efficient drainage paths into their hollow section mullions, which in practice further increases their rain defence effectiveness. 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 - UL has been tested to HEVAC 4th Edition. Easy to install – UL can either be delivered to site pre-assembled or as a kit of parts. A wide range of options - it is available in various shapes, configurations, materials, finishes and coatings to meet the requirements of almost any project. Louvres can be extruded or roll-formed; either mill finish, polyester powder painted or anodised; plain, perforated or stucco embossed. Louvre panels can incorporate mitred corners, special shapes and louvre doors. Colt also has a range of turret units. If noise reduction is required, acoustic louvre panels may be used.
