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.
