Ridgelight 25-40°

Ridgelight 25-40° is a classic rooflight solution, where two rows of Modular Skylights are connected at the ridge. The dual pitched Ridgelight solution is ideal for buildings with large roof openings.

Ridgelight 25-40° 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.

Optional gable modules can be supplied with different types of glass or infill panels, depending on the visual expression you want to achieve with the installation.

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 the sub-construction needed for installation.

VELUX comfort venting Modular Skylights meet the requirements of the harmonised standard EN 60335-2-103 (2015). Therefore, comfort venting skylights can be installed within reach, i.e. at installation heights below 2.5 m above floor level (inside) and ground level (outside). We recommend that you observe national regulations and consider if the planned specific use of the building requires additional safety measures that must be applied by the installer/user to prevent serious injury. For more details and information on smoke venting Modular Skylights, please refer to the Technical Handbook and the safety guidelines delivered with each product. If VELUX roller blinds are installed, please observe recommendations.

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.

Prefabricated Modular Skylights from VELUX come with perfectly matching cladding, flashing and roller blinds. 

Modular Skylights come with standard low-energy double or triple glazing with the following features: 

• 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)

The 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)).  

Create a rooflight solution to match your design

By adapting the interior lining, modular Ridgelights 25-40° can be used in non-square designs, e.g. obtuse angles, acute angles or ovals. By using adapted linings, the modular skylights meet the demands of modern architecture featuring irregular or curved shapes.

Create an asymmetrical solution

Modules of different heights can be combined to form an asymmetrical Ridgelight solution that bridges roof sections of different height and slope. Using glazing with different characteristics on each side of the Ridgelight help maximize daylight and minimize heat intake.
