Monolight (formerly Vitral SkyVision)

Monolight is a bespoke single unit rooflight which can transform a dull room by flooding the space with natural light from above. Due to the glass top construction the light incidence is maximised, meaning that the light area is equal to the hole in the roof. Monolight consists of a glass top unit and a built-in wooden upstand and is available as a fixed or comfort venting unit.

Monolight fixed is a non-venting single unit solution that provides daylight through the roof, and is a perfect solution when making natural light a priority. For a nice finish the builders inner lining can be connected into the groove just under the glazing.

Monolight venting is an optimal solution where light and natural ventilation are required. An elegant and functional product, with a fully integrated chain actuator concealed within the wooden upstand. For a clean finish the builders inner lining can be connected into the groove just under the glazing.

Monolight Burglary-resistant is available as versions of Monolight fixed and venting and of Linearlight fixed. These products are approved according to EN 1627 and NEN 5096 Resistance Class 2. A vapour barrier is pre-fitted to the upstand.

Monolight Walk-on is a non-venting single-unit rooflight intended for residential use and ideal for houses that require both natural light and an accessible roof. Made with toughened and laminated glass, the rooflight is designed to be safe to walk on and can be provided with double glazing and an optional anti-slip feature. A vapour barrier is pre-fitted to the upstand.

Modular Rooflight modules are supported by a 10-year guarantee. Actuators and other electrical components that are part of the modular system come with a three-year guarantee.

VELUX Commercial specialists can offer support throughout design, specification and installation.

Monolight module construction

1. Aluminium frame (height varies depending on glazing unit)
   Pre-assembled corners and powder coated aluminium frame with the standard colour RAL 7043, gloss 30.
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 gaskets on the alumium profiles provide watertight and airtight construction.
5. Upstand 
   90° angle provides a straight connection with the interior. The timber-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 blind
   Hidden pre-wiring is optional for nice and easy installation of VELUX roller blinds.

1. Aluminium frame (height vary depending on glazing unit)
   Welded corners and powder coated aluminium frame with the standard colour RAL 7043, gloss 30
2. Insulating Glass Unit (IGU)
   Available in double and triple glazing, standard with LowE coating or with additional Sun protection.
   Walk-on:
   Outer 3-layer laminated glass: Special walk-on glass construction (EVA Foil) with step.
   Inner 2-layer laminated glass: (PVB foil), space between outer and inner glass is filled with air. An anti-slip coating is optional.
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 gaskets on the timber upstand provide watertight and airtight construction.
5. Internal lining
   90° lining defining the clear internal part of the product and provides a great connection with the interior.
6. Lining groove
   Makes the plaster board connection easy and intuitive during installation.
7. Insulating mineral wool
   Insulation material in the frame ensures a good insulating performance of the entire produc.
8. Vapour barrier
   The pre-fitted vapour barrier ensures an easy and secure connection to the vapour barrier in the roof construction.

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

Monolight burglary-resistant. Stronger fixation of the top unit to upstand and roof.

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, thus there is no visual difference between fixed and vented modules.

The stroke length is 260 mm resulting in an opening of approximately 190 mm. The venting 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 chain actuators depending on the clear internal area and module width. For further information, see size overview.

The modules can be controlled by either a VELUX io-homecontrol a Motorlink™ or a third-party ± 24 V DC control system.

Monolight Walk-on

Walk-on is designed for residential application and to be safe to walk on. It can be provided with double glazing and an optional anti-slip coating.
Modular Rooflights Walk-on with pedestrian walkability are only intended for light residential or light commercial use. They are not intended to be installed for industrial use, or in any other public or domestic situation where for instance driving through, use of cleaning agents, detergents and other chemicals may occur.

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.

Monolight low-energy triple glazing

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). For Walk-on only, double glazing with Ug-values of 1.3 W/m²K is available.
• Toughened outer glass. For Walk-on, toughened and three-layer laminated glass (EVA foil) with step.
• 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)
• Optional anti-slip for Walk-on
• 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 of the rooflight preventing thermal breakage.
