Step Longlight/Ridgelight

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.
