When designing a home extension or connecting adjacent buildings with different ceiling heights, architects and homeowners often face a unique challenge: how to seamlessly join the structures without losing valuable natural light. The Wall-mounted Longlight 5-45° is a revolutionary residential modular skylight system designed precisely for this purpose.

Engineered to connect different building heights—using a flat or sloped roof as the base and a vertical wall at the top—this innovative VELUX system doesn't just solve a structural puzzle; it dramatically adds daylight, height, and a sense of spaciousness to any room.

Here is why the Wall-mounted Longlight 5-45° is a versatile, must-have solution for modern building extensions and architectural renovations.

1. Innovative Design for Home Extensions

The Wall-mounted Longlight consists of a continuous row of modular skylights that are mounted flush against a vertical wall at their highest point. This makes it an incredibly powerful tool for bringing daylight much further into a building, particularly in home extensions where traditional windows simply can't reach.

Whether you are joining a new addition to your existing home or connecting two adjacent buildings, this system permits a flawless transition between different ceiling heights. Furthermore, because these skylights can be installed at a steep pitch of up to 45°, they draw the eye upward, actively adding vertical space and volume to your interior.

2. High-Performance Comfort and Ventilation

Like all premium VELUX modular skylights, the Wall-mounted Longlight system isn't just about static glass. The system includes options for both fixed skylight modules and motorized comfort venting modules.

The motorized venting modules can open up to 410mm, acting as a crucial component of your home's natural climate control. Powered by an integrated chain actuator, this ventilation can be fully automated and controlled using the VELUX INTEGRA® system or tied into your preferred smart home building management system to keep your air fresh and comfortable year-round.

3. Superior Insulation and Structural Strength

When you are tying a glass roof into a vertical wall, structural integrity and insulation are non-negotiable. The sash and frame profiles of these modular skylights are forged from an advanced composite material consisting of 80% pultruded fiberglass and 20% polyurethane.

This specific blend offers excellent profile stiffness and bending strength, ensuring the skylight can bear weight and withstand the elements. Simultaneously, the polyurethane provides outstanding thermal stability and high insulation performance. Because the modules are completely pre-fabricated, they are rigorously tested in controlled environments against extreme weather events, guaranteeing a robust, weather-tight addition to your home.

4. A Fully Watertight Turnkey Solution

Worrying about leaks at the junction where a roof meets a wall is a common concern in home additions. The VELUX Wall-mounted Longlight completely eliminates this risk by providing a turnkey, pre-fabricated system.

Every delivery includes dedicated claddings, precision flashings, and a specialized vapor barrier connection strip. These meticulously designed components guarantee a watertight rooflight and glass roof structure. The system's fast and easy installation process means your interior is closed to the elements quicker, reducing overall labor costs and accelerating your renovation timeline.

5. Factory-Fitted Sun Control

For spaces where you want to optimize daylight without suffering from midday glare or excessive heat, sun control is essential. To make the installation even smoother, internal roller blinds can be pre-mounted directly from the factory, ensuring your new glass roof is beautiful, functional, and perfectly shaded from day one.
