Roof Louvre Blade - Commercial (RLB-C)

Product features and details.
1
Product Overview

Roof Louvre Blade – Commercial (RLB-C), are smoke vent and air supply units used in natural smoke and heat exhaust ventilation systems (nSHEVS). Mounted on roofs, louvre smoke vents exhaust smoke and heat from a building, allowing low level escape routes to be kept clear of smoke. Roof Louvre Blade – Commercial (RLB-C) units are fully certified to BS EN 12101-2. They are particularly suited to industrial and commercial buildings and may also provide natural comfort ventilation.


They are available in a wide range of sizes, louvre options and types of upstands. With the addition of polycarbonate glazing they can also bring natural daylight into the building. They may be installed at any angle, 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.
