Multiple rows of skylight modules that can be combined to create a large glass roof.
- Flat roof
- Flat roofing material
- Roof opening extra large
- Rooflight installation pitch 5-40°
- Ideal for construction of large, glazed roofs
- Easy, fast and secure installation
- Great design flexibility
VELUX modular Longlight and Ridgelight solutions enable great daylight design in buildings with large, open atriums.
The modular skylights enable fast and intuitive design when multiple rows are simply put together to cover the atrium – big or small.
For maximum daylight, we recommend either mono-pitched Longlights installed at low angle or Ridgelights at 5° with beams.
For optimum thermal comfort, we recommend Ridgelights 25-40° with venting modules.
The rooflights are connected via drainage gutters and supported by structural beams. The beams also serve as support for the sub-construction used for mounting the skylight modules.
VELUX modular skylights are delivered with a 10-year guarantee on modules and flashings.
VELUX skylight specialists offer support throughout design, specification and installation, including design of structural beams and drainage gutters. Please note that beams, drainage gutters and sub-constructions are not included in the VELUX delivery.
