Performance
The Step Longlight and Step Ridgelight solutions enable great daylight design in buildings with large, open atriums.
The solution consists of multiple rows of VELUX modular skylights connected as Step Longlights 5-25°, Step Ridgelights 25° or as Step Ridgelight 5-25° on Girder.
The rows are connected by a factory finished flashing that ensures drainage of water between the rows. The rows must be supported by structural beams on the inside of the building.
VELUX modular skylights are delivered with a 10-year guarantee on modules and flashings.

VELUX modular skylights require the following minimum and maximum measurements:
- Module width: 675-1000 mm
- Module height: 600-3000 mm
VELUX modular skylight system is a turnkey solution comprising prefabricated skylight modules with dedicated claddings, flashings and vapour barrier connection strip to allow for design of watertight rooflight and glass roof structures.
Comfort ventilation is possible via an integrated chain actuator that can be controlled with VELUX INTEGRA® system or with your preferred building management system. Smoke ventilation can only be controlled with your preferred building management system.
For optimal daylight and heat control consider internal roller blinds that can be pre-mounted from the factory.
CAD/BIM
The VELUX modular skylight profiles (sash and frame) are made of pultruded fiberglass (80%) and polyurethane composite (20%). The composite material provides high insulation performance and thermal stability as well as excellent profile stiffness and bending strength.
Due to the concept of prefabrication, we are able to test our products extensively against all thinkable hazards and stressful events. Tests are performed in controlled environments in accordance with harmonized standards for both Windows and doors and for Smoke and Heat control systems.
