VELUX Modular Skylight – Ridgelight 25°–40°
The ideal daylight solution for buildings with large roof openings.
Ridgelight 25–40° is a classic rooflight solution, where two rows of VELUX Modular Skylights are connected at the ridge. With venting skylight modules on both sides is an optimal solution for buildings that require day or night cooling.
The Ridgelights can be supplied with different types of glazing on each side to control heat and glare according to the orientation of the building.
The self-supporting solution is suitable for flat rooflights and ridgelights with a roof opening width of between 1.1 and 4.5 m for fixed modules and 1.4 to 4.5 m for venting modules.
