Velux GGU MK06 006640 780x1180 White Polyurethane Smoke Ventilation Window

The VELUX smoke ventilation window is designed to improve fire safety by allowing smoke and heat to escape upwards in the event of a fire. This helps keep escape routes and fire brigade access clear, preserving the building’s fire-resistant properties and reducing potential damage to valuable assets.

Ideal for stairwells, annex connections, industrial buildings, and offices, this window is part of the VELUX natural smoke and heat exhaust system, ensuring compliance with UK building regulations.
