Modular Rooflights

When people spend 90% of the time indoors, designing with daylight becomes an obligation. Great daylight design brings the qualities of the outdoors into the building. Daylight brightens the mind and invigorates the body. It carries warmth, provides clarity, and creates spaces for meeting, talking, relaxing and learning. Modular Rooflights offer a range of product features and accessories to optimise the indoor climate by controlling daylight, heat and ventilation.

Daylight and heat control

Control daylight and heat to create the best indoor climate. Modular Rooflights are designed to optimise the indoor climate and offer options to control daylight and heat.

The blind cloth of VELUX roller blinds is pulled on two tension steel wires on pulley wheels, which are accessible, when the roller blinds are installed on rooflights within reach, and therefore can cause serious injury if a person gets in contact with this during the electrical operation of the blind. VELUX roller blinds 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. No instruction or measure can eliminate the inherent hazards resulting from installation heights below 2.5 m.

We recommend you to observe national regulations and consider if the planned specific use of the building requires that additional safety measures must be applied by the installer/user to prevent serious injury.

Comfort ventilation

Natural ventilation through the roof with Modular Rooflights. Electrically operated venting modules ensure fresh air and optimum indoor comfort.

Comfort venting modules

An optimal solution where light and natural ventilation is required. In venting modules for both Monolight and Linearlight, the actuator is fully integrated in the wooden upstand. The actuator is not visible from the inside when the module is closed, thus there is no visual difference between fixed and venting modules. A venting module is operated by either 1 actuator or 2 synchronised chain actuators depending on the clear internal area and module width.
