Exterior cladding VELUX roof windows As standard the window is supplied with maintenance-free exterior cladding of grey aluminium. The grey colour has colour code NCS S-7500-N, making it easy to fit in with different colours and types of roofing materials. The colour has also been selected to obtain harmony, even under very different light conditions, between the grey cladding and the window glass. One of the reasons why NCS (Natural Color System) has been selected is that the colours in this system do not contain environmentally damaging pigments. Frame and sash VELUX roof windows are made of pine with triple coat finish. GIU/GGU/GHU/GPU have a timber core with two coats of white polyurethane lacquer finish. Ventilation flap The control bar with ventilation flap is positioned at the head of the sash. The ventilation flap makes it possible to get fresh air in the room without opening the window. An air filter keeps out dust, insects, etc. when the ventilation flap is open. Blind brackets VELUX roof windows are supplied with brackets, ensuring an easy and simple installation of VELUX interior decoration and sunscreening products. Barrel bolt VELUX roof windows can be fully rotated and securely locked with the barrel bolt for easy cleaning of the exterior pane. In addition, the centre-pivot roof windows can be secured in open position. Insulating glazing unit All VELUX roof windows are supplied with insulation panes in many variants. Data plate The data plate with product code is used as documentation for production and subsequent service. In addition, the data plate is used for ordering VELUX decoration and sunscreening products. Quality control Roof windows are particularly exposed to changing weather conditions, and VELUX roof windows are therefore designed to be able to resist such conditions. In addition, all functions have been tested so that the window can withstand the varying degrees of exposure. Section 3.00.02 Products q Roof windows 022009 2009 VELUX Group
