Velux Smoke Ventilation System

Natural smoke and heat exhaust ventilators are typically used in common access areas such as stairwels and annex connections as well as in industrial buildings and offices. The smoke ventilation 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 conrol system or via an auxillary wall switch.

The new high-performance insulation system uses a core of thermally modficied timber in combination with a special gasket for a better airtight seal that minimises heat loss and energy consumption. 

The extrernal 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).

Velux smoke ventilation systems are tested and certified accdording 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.

Package includes: 

Single electrically operated GGU white Polyurethane roof window with laminated inner pane for additional safety, 1 smoke sensor, 1 break glass point, 1 wall control (KFX 210) and suitable flashing. Additional smoke sensors and break glass units can be purchased separately.
