VELUX GGU SD0L140 Smoke Ventilation System Packs, Slate Flashings

For situations where smoke ventilation is required. Available for 1m²
(SKO6 size) or 1.5m² (UKO8 size) of smoke free ventilation area.

GGU 0073 Roof Window + Flashing for slate up to 8mm thick (suitable for 15°-90° roof pitch)

Package includes: Single electrically operated GGU White polyurethane roof window, toughened outer pane with clear and clean coating with laminated inner pane for additional safety, 1 smoke sensor, 1 break glass point, 1 wall control unit and suitable flashing or kerb.

This is a centre pivot window.

The laminated inner pane makes for added safety. This is because, should the glass break in an unfortunate event, the pieces will remain within the window frame, as opposed to shattering on the ground creating a hazard. The clean and clear coating makes your windows stay cleaner for longer, and makes them easier to clean when you need to.

System can be upgraded to comply with aerodynamic smoke ventilation requirements by the inclusion of the optional KFD external wind deflector.


System tested and certified to EN ISO 12101-2 Smoke and heat control systems .

10 year guarantee for windows and panes, 3 year guarantee for the electrical items.
