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.

Smoke sensors, control systems and break glass units to be purchased separately - please see the options above on the drop down menu.

The VELUX flat roof window also offers ventilation for daily use, keeping occupants comfortable by letting in fresh air as needed. It is a complete natural smoke and heat exhaust ventilator system, which 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.
