Designed for life: a flexible portfolio for every situation

This flexible product offering, covering various performance, aesthetic, and budget requirements, allows architects to design without compromise.

Scenario 1: Top Energy Parameters (nZEB, Passive House)

In projects with high thermal insulation requirements, the solid wood GLL and maintenance-free GLU roof windows (with a wooden core covered by a 3-5 mm thick layer of white polyurethane), equipped with highly insulating glazing 85 [1], set a new standard. The extraordinary value of Uw = 0.9 W/m²K [2], further supported by the integrated insulation system ThermoTechnology™, allows architects to design large glazed areas without compromising the thermal envelope of the building.

Scenario 2: An Oasis of Calm in the City (Acoustic Comfort)

In a noisy and densely built urban environment, comfort is defined by silence. The GLL and GLU roof windows with 85 glazing combine excellent thermal insulation properties with a significant reduction in noise (Rw = 38-39 dB), enabling architects to design quiet, daylight-filled interiors even in acoustically demanding conditions.

Scenario 3: Smart Modern Home (Automation)

For clients seeking contemporary comfort, electrically and solar-controlled roof windows are available at a more affordable price. Thanks to insulating triple glazing 64 with anti-condensation treatment [3] and a fully integrated, visually invisible motor, the windows appear sleek and minimalist. An integrated rain sensor provides real peace of mind – the window automatically closes at the first drops of rain, protecting the interior even when the residents are not home or are engaged in other activities.
Control is simple using a remote control, and the windows can also be connected to smart home systems. Architects can choose either the electric or solar version at the same price, allowing for greater flexibility in design.

Scenario 4: Freedom in Design (Panoramic Views)

For architectural designs where views are crucial, the GNL pivot-and-tilt roof windows in wooden finish and maintenance-free GNU with polyurethane layer offer unobstructed openings up to an angle of 45°. This creates the feeling of a "mini-balcony," which greatly enhances the connection between the interior and the exterior.
Until now, pivot-and-tilt roof windows were perceived as a premium solution intended primarily for high-end projects, especially due to the higher prices of previous versions. The new GNL and GNU models now bring the experience of unobstructed views to a significantly wider group of customers.

Scenario 5: Budget-Conscious Renovations (Price/Performance Ratio)

Renovation projects are often associated with tight budgets. Glazing 64 now represents a base solution that is affordable. It allows architects to choose the quality and long lifespan of VELUX products while avoiding replacements with lower-quality alternatives as a cost-saving measure. Customers can choose from several types of roof windows – pivot, pivot-and-tilt, or remote-controlled. All have a uniform design, with insulating triple glazing 64 and full compatibility for mutual combinations, offering broad options while maintaining affordable prices.

Designed for a Sustainable Future

"Sustainability is not an addition, but the starting point of our design," says Zsolt Szabó. VELUX products support highly energy-efficient and sustainable construction by enhancing the energy efficiency of buildings, optimizing the supply of daylight, and contributing to a healthy indoor environment through natural ventilation.
Roof windows are designed with circularity in mind – they are durable, repairable, and made from FSC®/PEFC® certified wood. They also provide the documentation necessary for sustainable building certifications and support the corporate goal of the VELUX group – achieving lifelong carbon neutrality by 2041.

An Essential for Summer Comfort

"To ensure year-round comfort and optimal functionality, it is important to perceive roof windows as part of a fully integrated system," concludes Zsolt Szabó.
In energy-efficient buildings, thermal insulating exterior shutters (e.g., SML) are an essential element for regulating solar gains, preventing overheating, reducing dependence on air conditioning, and maintaining the projected energy demands of the building.
