VELUX Modular Skylight – Northlight 25°–90°
The rooflight series for monopitch or saw tooth roofs.
Northlights are rows of rooflight modules installed at up to 90° in order to provide large amounts of glare-free daylight due to their north-facing orientation.
They are ideal for spaces that require soft light for optimum indoor illumination, e.g. in schools, offices, museums and galleries.
The Northlight solution does not generally require a sub-construction for installation. The modular Northlights allow fast and easy closure of the roof to reduce costs and save time.
