Description
Ventilated upstand.
Features and benefits:
- Fitted under a roof-mounted natural ventilator to provide weathered extract ventilation through two controllable side dampers irrespective of the weather.
- Made from lightweight aluminium.
- Aerodynamically-formed flaps are integrated into the device and open after closing the ventilator on top of it and thus allow ventilation to continue to operate even in rainfall.
- Night-time cooling.
- Smoke ventilation (via a vent placed on the top of the upstand)
- Suitable for both new and refurbished buildings
- Tests to confirm that Weatherlite in no way affects the performance of the ventilator placed above it as assessed according to the EN 12101-2 standard
- Can be fitted (including its dampers) with insulated panels to reduce heat losses.
Also available without controls and with a sheet metal top section where only weathered ventilation is required.
