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 skylight specialists offer support throughout design, specification and installation, including design of structural beams. Please note that beams and sub-constructions are not included in the VELUX delivery.

Venting skylight modules have a recommended minimum installation height of 2.5 m above floor level (inside) and ground level (outside).
In case of installation below that level, safety measures must be applied by the installer/user to prevent serious injury.

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.

Pre-fabricated modular skylights from VELUX come with perfectly matching cladding, flashing and roller blinds.

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.

In combination with low energy glazing units, the modular skyligths are able to achieve one of the lowest overall U-values for frame and glazing assembly in the skylight market (Uw values down to 0.86 W(m2/K)).
