    1. Aluminium frame 
    (height vary depending on glazing unit) Pre-assembled corners and powder coated aluminium frame with the standard colour grey.

    2. Insulating Glass Unit (IGU)
    Available in double and triple glazing, standard with LowE coating or with additional Sun protection.

    3. Silk screen print
    The silk screen print gives a nice finish as well as UV protection to the gaskets and the underlying construction.

    4. Double gaskets
    The top plate gasket and the gasket on the aluminium profile provide a watertight and airtight construction.

    5. Upstand
    90° angle provides a straight connection with the interior. The wood-EPS sandwich construction provides a stable and well-insulated upstand for a good insulating performance of the entire product.

    6. Lining profile
    This multifunctional part defines the clear internal part of the product. It offers the possibility for a secure connection to the vapour barrier in the roof construction. It also makes the flush plaster board connection from ceiling to glazing easy and intuitive during installation. Vapour barrier and inner lining are to be supplied by others. The profile also supports installation of an optional roller blind.

    7. Pre-wiring for roller blinds
    Hidden pre-wiring is optional for nice and easy installation of VELUX roller blinds.

    8. Minimized beam
    The beam with optimized reinforcement is supporting the top unit while it is kept as slim as possible in order to maximize light entrance. 

    9. Drainage gutter
    Rain water flows down the drainage gutter and is transported to the outside of the product.

  • Functions and sizes
    Modular Rooflights are made to measure and can be configured, manufactured and delivered in bespoke sizes for specific requirements. Linearlight fixed is available as burglary-resistant versions according to EN 1627:2011 and NEN 5096-2012+A1:2015: Class 2 (RC 2).

    Venting modules

    In venting modules, the actuator is fully integrated in the wooden upstand.

    The actuator is not visible from the inside when the module is closed, therefore there is no visual difference between fixed and venting modules.

    The stroke length is 260 mm, resulting in an opening of approximately 190 mm. The venting modules modules meet the requirements of the harmonised standard EN 60335-2-103(2015), see comment below for reference. A venting module is operated by either one actuator or two synchronised actuators depending on the clear internal area and modules width. For further information, see size overview.

    The modules can be controlled by either a VELUX io-homecontrol, a Motorlink™ or an Open System ± 24V (OS ±24V DC) control system.

    Comfort venting Modular Rooflights 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).

    Modular Rooflights have a recommended minimum installation height of 2.5 m above floor level (inside) and ground level (out-side). 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.

  • Glazing

    Modular Rooflights glazing unit

    Modular Rooflights can be designed with double or triple glazing units with the following features:

    • Insulated glazing (Ug values down to 0.5 W/m2K). 
    • Toughened outer glass.
    • Laminated inner safety glass. Class P4A for burglary-resistant glazing.
    • Warm edge spacer (protects insulation properties over time and minimises the risk of condensation at pane edges)
    • Sun protection coating (optional)
    • The glazing unit is glued into the aluminium frame with a UV resistant silicone
    • The glazing unit has a 115mm black silk print along the edge (50 mm at beam side) of the rooflight preventing thermal breakage.
