VELUX modular Longlight and Ridgelight solutions enable great daylight design in buildings with large, open atriums.

The modular skylights enable fast and intuitive design when multiple rows are simply put together to cover the atrium – big or small.

For maximum daylight, we recommend either mono-pitched Longlights installed at low angle or Ridgelights at 5° with beams.

For optimum thermal comfort, we recommend Ridgelights 25-40° with venting modules.

The rooflights are connected via drainage gutters and supported by structural beams. The beams also serve as support for the sub-construction used for mounting the skylight modules.

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 and drainage gutters. Please note that beams, drainage gutters 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.

Pre-fabricated modular skylights from VELUX come with perfectly matching cladding, flashing and roller blinds.

The VELUX 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 unique skylight solution

By adapting the interior linings, the modular skylights can meet the demands of modern architecture featuring irregular or curved shapes, e.g. obtuse angles, acute angles or ovals.

Adaptation of the interior lining creates an oval shape by means of rows of Longlights

 

Asymmetrical solutions

The great flexibility of VELUX Modular Skylights enables design of asymmetrical atrium solutions.

By combining Ridgelight modules of different heights, you can create an asymmetrical glass roof solution. The Ridgelight solution can be installed between roof sections of varying height. This solution is not a standard solution, project specific evaluation needed.

Combining solutions

Combining different types of modules creates beautiful solutions that optimize comfort and ventilation. Let us help you find the right solution for your next design idea.
