Roof Louvre Blade - Residential Glass Access (RLB-RGA)

Product features and details.
Roof Louvre Blade Residential Glass Access Description

Roof Louvre Blade – Residential Glass Access (RLB-RGA) louvre smoke vent and air supply units incorporates a manually operated access hatch base for roof access and may also be used in natural and mechanical 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-RGA are fully certified to BS EN 12101-2. They are particularly suited to residential and institutional buildings and may also provide roof access and natural comfort ventilation.

They are available in a wide range of sizes, louvre options and types of upstands. With the addition of double glazed glass glazing they can also bring natural daylight into the building. 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.
