Comfort Ventilation for Dome Rooflights

Optimise the indoor climate with venting Dome Rooflights

Dome Rooflights are available with different comfort ventilation options to suit your specification requirements. 

Permanent rooflight ventilation

Permanent rooflight ventilation

Permanent Vent

As the name suggests, this option is permanently open and shielded from the elements by the outer skin of polycarbonate.

Please note that Permanent Vent is only available with uPVC Dome Rooflights.

Manual rooflight ventilation

Manual rooflight ventilation - Rota vent

Rota Vent

The pole-operated Rota Vent directs air flow upwards towards the glazing, reducing the risk of condensation and preventing cold draughts, whilst resisting ‘in-blown’ roof debris and water ingress.
Please note: Rota Vents are only available with uPVC Dome Rooflights.

Manual Hinged Vent

Operated by a winding rod, the whole Dome Rooflight top hinges to allow ventilation through the rooflight.

Electrical rooflight ventilation

Electrical rooflight ventilation - Electrical hinged vent

Electrical Hinged Vent

Electrical rooflight ventilation - Vertical Lift Vent

Vertical Lift Vent

Ideals for spaces with limited room, a Dome Rooflight with Vertical Lift Vent provides ventilation by lifting the lid vertically up. Wiring to the motor and switch is not completed by VELUX Commercial.

Please note: Vertical Lift Vent is only available with metal Dome Rooflights.

Mechanical Ventilation

Mechanical ventilation can also be integrated into our polycarbonate rooflight solutions by fitting a power fan to the rooflight unit.

There are two options:

  • Power fan unit built into the polycarbonate glazing. This option allows either a 150mm or 225mm power fan to be specified
  • A smaller fan mounted into the side wall of the kerb. With this option, the kerb will be higher to provide the 150mm clear upstand height to the base of the fan unit.
