Universal Louvre 1UL/SH

Colt International Ltd Variant:

A range of external universal louvres for screening and/ or ventilation.

Jump to:
+44 (0)23 9245 1111 Website

Application

Screening and/ or ventilation including plant rooms and areas requiring a high level of rain defence.

Description

A range of external universal louvres for screening and/ or ventilation.


  1. 1UL is a single bank louvre system designed for screening or cladding applications when rain defence is not of primary importance.
  2. 2UL is a double bank louvre system which provides high airflow performance with a good degree of rain defence.
  3. 3UL is a roll-formed triple bank louvre system designed for applications requiring ventilation with the maximum degree of rain defence.
  4. Universal Louvre Roof Turrets are available in a wide range of standard sizes in single bank or double bank configurations.


Features and benefits:

  • Highly aerodynamically efficient; this reduces air resistance, allowing the plant and the aperture to be minimized thereby saving running costs.
  • Enhanced rain defence performance (2UL and 3UL only).
  • Durable and maintenance free: 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: tested to HEVAC 4th Edition (1UL, 2UL and 3UL).
  • Easy to install: can either be delivered to site pre-assembled or as a kit of parts.
  • A wide range of options: 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 anodized; plain, perforated or stucco embossed.
