Roof Louvre Blade (RLB-R) Description

Roof Louvre Blade – Residential (RLB-R) 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. RLB-R are fully certified to BS EN 12101-2. They are particularly suited to residential and institutional buildings and 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 wind shields 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.
