VELUX Northlight 25-90°
by VELUX Commercial
A rooflight series for sloped, shed or saw tooth roofs.
Northlights are rows of modules installed up to 90° in order to provide large amounts of glare-free daylight, ideal for spaces that require soft light for optimum indoor conditions, e.g. at schools, offices, museums and galleries.
The Northlight solution does not require a sub-construction for installation and can be integrated into a sloped roof.
The modular Northlights allow fast and easy closure of the roof to reduce costs and make room for the interior works.
Suitable for:
- Sloped, shed or saw tooth roof
- Flat roofing material
- Opening width in roof min./max. 0.6-3.1 m (for venting modules 0.8-2.5 m)
- Rooflight installation pitch 25-90°
Key benefits:
- Possibility of upright design
- Prevents glare and lets in a soft light when facing North
- Designed for installation directly in sloped roofs without adding a sub-construction
VELUX modular skylights are delivered with a 10-year guarantee on modules and flashings.
