Open Sky Louvres can be fitted into any roof or glazed construction whilst the other two units have been specially designed for architectural feature walls and atria.
Open Sky for Roofs

Hopper Louvre Vent

When closed the Hopper Louvre blades provide an attractive surface and the clean, smooth lines of the louvre are enhanced by a fully concealed operating mechanism.
The Open Sky Louvres for walls and roofs both offer optional translucent blades which provide excellent daylighting. When fully closed, the louvres' average diffused light transmission is in excess of 80%.
Wall mounted Vent

All louvre ventilators are fitted with fusible links as standard as an override facility to release the louvers at a pre-set temperature in the event of a fire.
