Description

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.

Features and benefits:

Prefabricated solution for large, glazed roofs.
Elegant design with option of slim beams between the rows/ steps.
Maximum daylight through the roof.

Glazing:

Insulated glazing (Ug values down to 0.5 W/m²K).
Toughened outer glass.
Laminated inner safety glass.
Falling through safety.
Sound insulation (traffic, rain and hail).
Warm edge spacer (protects insulation properties over time and minimizes the risk of condensation at pane edges).
Step pane (leads water off the unit).
Sun protection coating (optional).
