Smoke ventilation for flat roof
VELUX® flat roof windows for smoke ventilation keep escape and fire access routes free by leading smoke and heat up and out of a burning building. This means that buildings retain their fire-resistant properties longer and that damage to valuable assets is limited as much as possible.
The VELUX® flat roof window also offers ventilation for daily use. Keeping occupants comfortable by letting in fresh air as needed.
The VELUX® Smoke Ventilation System – a complete natural smoke and heat exhaust ventilator system complies with building regulations on smoke ventilation.
Natural smoke and heat exhaust ventilators are typically used in common access areas such as stairways and annex connections, as well as in industrial buildings and offices.

Smoke and heat ventilation windows
Natural smoke and heat exhaust ventilators are typically used in common access areas such as stairwells and annex connections as well as in industrial buildings and offices.
The smoke ventilation window is activated either automatically by a smoke sensor or manually with a break glass point.
Natural ventilation for daily comfort is activated with the integrated switch in the control system or via an auxilliary wall switch.
Excellent energy efficiency
The new high-performance insulation system uses a core of thermally modified timber in combination with a special gasket for a better airtight seal that minimises heat loss and energy consumption.
The VELUX® smoke ventilation window is also available with triple-glazing for maximum insulation.
Same design as other VELUX roof windows
The external design of VELUX smoke ventilation windows matches that of standard VELUX roof windows ensuring a harmonious appearance when installed in the same roof
(when wind deflectors are not required).
Tested and certified
VELUX® smoke ventilation systems are tested and certified according to EN ISO 12101-2 for roof pitches 15°-90°. Available without wind deflectors where a geometric opening area is required, and with wind deflectors where an aerodynamic area is required.
