VELUX smoke ventilation for flat roof.


VELUX roof windows with smoke and heat ventilation* are perfect for buildings that need to meet safety requirements while providing comfort for the users of the building. In the event of a fire, the window automatically opens to let smoke and other harmful gasses out of the building.

The windows can also be opened and used to provide natural ventilation to the building as needed.

Smoke and heat ventilation windows are typically used in common access areas such as stairwells and annex connections as well as in industrial buildings and offices.
