Linearlight

Linearlight is designed to create wide, uninterrupted daylight sources, which is ideal for these types of spaces. This installation uses an advanced connector system that allows for larger bands of natural light without the need for additional support. This means that the light incidence is maximized because the light area is equal to the roof opening, ensuring full utilization of the opening without intrusive framing blocking daylight. This makes Linearlight particularly suitable for creating continuous bands of natural light, providing consistent daylight distribution across large open spaces.

Linearlight contributes to sustainability goals through:

• Use of 99.6% FSC or PEFC certified wood in European factories.
• Natural ventilation capabilities that reduce reliance on mechanical systems.
• High thermal performance with U_g-values as low as 0.5 W/m²K for triple glazing.
• Optimized daylight penetration: Installing skylights increases daylight in the room, which can reduce the use of artificial lighting by up to 60%

Linearlight offers extensive design flexibility, making it ideal for seamless integration with modern architecture. Its made-to-measure modules can be configured to the millimeter, with widths ranging from 250 to 3000 mm and lengths from 250 to 2000 mm, depending on the module type. Upstand heights are also customizable, from 150 to 600 mm. It is available in both fixed and venting versions. A wide range of glazing options is offered, including double and triple glazing with various coatings to suit performance and aesthetic needs. Importantly, there is no visual difference between fixed and venting modules when closed, preserving a uniform appearance.

Linearlight has impressive performance ratings for various weather conditions:

• Resistance to wind load: Class C3.
• Watertightness: Class E1200 (tested to withstand water pressure equivalent to 1200 Pa).
• Air permeability: Class 4 (highest class)..
• An optional snow gasket can be post-mounted to prevent snow from getting between the modules.
• The glazing includes UV protection through the silk screen print around the edges.

Yes, ventilation options are available with Linearlight. The venting version includes motorized openings through chain actuators that are fully integrated in the wooden upstand. These modules can be controlled by either VELUX io-homecontrol® or Open System ±24V (OS ±24V DC) control system.

Linearlight is a lean, linear solution for flat roofs, ideal for fast retrofits or targeted daylighting, whereas VELUX Modular Skylights offer scalable, architectural flexibility for larger or more complex daylighting needs.

Key differences:

1. Application & Design Focus 
   Linearlight is designed for rooflight installations in flat roofs, creating long, narrow strips of daylight. 
   Modular Skylights are intended for larger roof glazing systems, often in more complex solution types or spans.
2. Installation Context 
   Linearlight is ideal for corridors, narrow rooms, or hallways in flat-roofed buildings. 
   Modular Skylights are typically used in large atriums or open-plan areas, where bigger daylight areas or multiple modules are needed.
3. Configuration options 
   Linearlight uses smaller, factory-assembled units configured in a linear series. 
   Modular Skylights offer a broader range of configurations (e.g., ridge, gable, wall-mounted) with larger module options and complex joining capabilities.
4. Target Use Case
   Linearlight is often specified in smaller-scale commercial renovations or retrofits.
   Modular Skylights are typically used in new builds or large-scale daylight design projects.
