Velux Wind Deflector for Pitched Roof Smoke Ventilation System

The Velux Wind Deflector has been designed as an upgrade for the Velux Pitched Roof Smoke Ventilation System to comply with the aerodynamic smoke ventilation requirements.

The Velux windows and wind deflectors have been tested for:

  • Operational reliability of the window including use for comfort ventilation.
  • Aerodynamically effective opening area determining the rate of smoke and heat exhaust ventilation.
  • Opening reliability with a snow load on the window.
  • Stability and the ability to operate even after exposure to a wind suction.
  • Low ambient temperature testing to determine the reliability of the system at low winter temperatures.
  • Heat resistance to determine the resistance of the window to heat from fire.
