Natural smoke and heat exhaust ventilators keep escape and fire brigade access routes free by leading smoke and heat up and out of a burning building. This means that buildings retain their fire-resistant properties and that damage to valuable assets is limited as much as possible. 

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. 

The VELUX Smoke Ventilation System – a complete natural smoke and heat exhaust ventilator system, facilitates compliance with building regulations on smoke ventilation.

The VELUX Smoke Ventilation System is available for 1m² or 1.5m² of smoke free ventilation area.
