Colt 2UL Universal Louvre fixed metal ventilation louvre system

Colt 2UL Universal Louvre is a roll-formed or extruded double bank system, used for screening and/or ventilation. It is very often used as plant room louvre, or indeed anywhere where plant needs to be covered up.

Product information

2UL is a double bank louvre system which provides high airflow performance with a good degree of rain defence.

When 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.

Colt Universal Louvre can be uniquely configured to provide the solution to your needs.

Here are some of the features and benefits of Universal Louvre:

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 EN 13030:2001.

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. See the options tab.

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.

Performance - Universal Louvre has been tested to EN 13030:2001. See the performance tab for the test results.

Options

Description

Colt Universal Louvre is a versatile louvre system providing either screening and/or rain defence in a wide variety of product options, materials and finishes.

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.

Mullions are concealed at maximum 1250mm centres and the points of support along their length are set in accordance with prevailing site wind pressures (as calculated and specified by a structural engineer).
