A Flat Glass AOV (Automatic Opening Vent) NSHEV (Natural Smoke and Heat Exhaust Ventilation) rooflight manufactured to BS EN 12101-2 for heat and smoke ventilation. The smoke vents come in two standard sizes, which achieve a Geometric Free Area (GFA) of 1.0 m² and 1.5 m² respectively.

Features and benefits:

Powered by two 24v concealed folding arm actuators.
Control Panel comes with electric lock, battery backup and 24v transformer.
Fully thermally broken aluminium frames prevent cold bridging, reducing the risk of condensation.
Fully insulated base frame provides excellent thermal efficiency.
Access and ventilation options.
Smoke, gas, wind, and rain sensors available.
Break glass and override switches available.
Full integration to building fire management system.
Excellent thermal performance, with total system U-values as low as 0.9 W/m²K achievable.
Quick and easy to install.
Minimal framework: daylight is maximized while the visible framework is minimized.
Can also be used for natural ventilation.
Can also be used for occasional access.
More daylight -> less artiﬁcial light -> energy savings.
