Ventilation louvres provide external weather protection to supply and exhaust duct openings. They are typically used in large commercial or industrial buildings where there is a need for a constant supply of air. Read More

Fixed louvres are designed to prevent rain from entering the building, while allowing moisture and air to escape from inside.

Adjustable louvres can be closed, either manually or using a powered mechanism, to control air movement, prevent heat loss and eliminate draughts and daylight penetration.

Louvres can be specified in aluminium or steel according to the requirements of the application.

They often provide acoustic damping for ventilation openings and plant rooms, absorbing the sound emitted by equipment while also providing weatherproof ventilation.

Louvred grilles and diffusers are fitted internally for duct terminals.
