The Roof Louvre Blade – Residential range of louvre smoke vent and air supply units are used in natural smoke and heat exhaust ventilation systems. Mounted on roofs, louvre smoke vents exhaust smoke and heat from a building, allowing low level escape routes to be kept clear of smoke. They may also provide natural comfort ventilation.

They are available in a wide range of sizes and types of upstands. They may be installed at any angle from 0 to 90°, but are generally installed horizontally and supplied with aerodynamic windshields as standard. They consume minimal energy during the opening and closing cycle and have high resistance to weather and are therefore suited for use on exposed and high wind areas. They provide good security, are impact resistant and do not create a fall hazard when open.
