1UL Universal Louvre is a roll-formed single bank louvre system designed for screening or cladding applications, as well as ventilation applications when rain defence is not critical.
Colt 1UL Universal Louvre is a roll-formed or extruded single (1UL) 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.
1UL is a single bank louvre system designed for screening or cladding applications when rain defence is not of primary importance. Where rain defence is needed, we recommend the use of either 2UL or 3UL.
Colt Universal Louvre can be uniquely configured to provide the solution to your needs.
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 - UL has been tested to HEVAC 4th Edition. See the performance tab for the test results.
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.
If noise reduction is required, acoustic louvre panels may be used.
“UL Select” is an Excel sheet which enables users to make their own selection of Colt louvre systems based on the weathering classification and aerodynamic performance required for the system. If the area of louvre or the airflow is known, the program provides the pressure drop. If the flow rate and the maximum pressure drop are known, the program provides the minimum size of louvre.

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).
Class D at all velocities. Single bank louvres are ideally applied in sheltered locations or where rain penetration may be acceptable.
