Description

A high performance louvre system to suit most applications. 1UL is a roll-formed Single Bank Louvre System designed for screening or cladding applications and ventilation application when rain defence is not critical. Double (2UL) and triple bank (3UL) Universal Louvre are designed for applications requiring ventilation with a good degree of rain defence. The louvres unite to create drainage channels for rain water while still permitting an easy airflow path.

Uninsulated panels available.

Noise control:

Acoustic louvre panels can be mounted behind the louvre. If a single bank of acoustic louvres does not provide the required noise levels then a second bank may be added. As an alternative, duct silencers may be selected to give the desired noise reduction.

There are 2 acoustic Louvre options:

  • Type R - Optimum acoustic performance with normal pressure drop.
  • Type LP - Normal acoustic performance with minimum pressure drop.

For performance details, contact Colt.
