Application

Ventilated upstand for fitting under a roof-mounted natural ventilator. Suitable for both new and refurbished buildings.

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.
