Roof Single Leaf – Residential Glass (RSL-RG) smoke vents are principally designed for smoke and heat ventilation in protected stairwells and corridors within residential apartments. They are available as square or rectangular in a range of sizes.
The RSL-RG is a high quality, high-performance flat roof smoke vent combining a double glazed flush glass rooflight, with hidden tandem actuators giving an unobstructed daylight view. The units incorporate a fully welded aluminium frame and cill detail for efficient drainage of rainwater and the double glazed warm edge glazing provides excellent insulation and sound reduction values. The smoke vent is operated by tandem 24 volt DC actuators opening fully within 60 seconds to release smoke and heat. They may also be used for roof access and to provide natural ventilation
