Product Description

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.

  • Centre pivot window made of high quality polyurethane, perfect for toilets, bathrooms and kitchens
  • For Geometric Smoke Ventilation, VELUX systems are tested and certified to EN ISO 12101-2 for roof pitches from 15-90°
  • For Aerodynamic Smoke Ventilation, VELUX systems are tested and certified to EN ISO 12101-2 for roof pitches from 15-60°
  • Double glazed unit with laminated inner pane for additional safety
  • System can be upgraded to comply with aerodynamic smoke ventilation requirements by the inclusion of the option KFD external wind deflector.
