GLU window is equipped with integrated ventilation flap. This unique solution lets in fresh air through a dust and insect filter even when the window is closed. Good for rainy days, and ensure a healthy indoor environment.

VELUX ThermoTechnology™

The new generation of VELUX GLU windows incorporates innovative materials and advanced technologies to deliver enhanced comfort, better energy efficiency, and lower heating costs.

With ThermoTechnology™, you benefit from windows that offer optimal protection against heat loss while improving airtightness compared to the previous generation – from Class 3 to Class 4. This improvement significantly boosts insulation performance, reducing energy consumption and enhancing comfort in your home.

A key element of ThermoTechnology™ is the use of thermally modified wood in the frames and sashes of the windows. This process, which involves heating the wood to over 175 °C, reduces its moisture content by up to 50%, making the material more stable and insulating. This method eliminates the need for chemical treatments, rendering the wood more resistant to aging and moisture. The result is a durable, resilient material with properties comparable to cedarwood.

The combination of thermally treated wood and an additional layer of water-resistant polyurethane provides excellent thermal insulation and protection against moisture, wind, and weather conditions. This new technology not only helps reduce your heating costs but also improves energy efficiency and comfort in your attic spaces.

Look for the ThermoTechnology™ seal on VELUX products – it guarantees outstanding thermal insulation for a better living experience.

Flashings

VELUX flashing: do I really need it?

Flashings are essential for the correct installation of roof windows. Precisely designed flashing details ensure a durable and neat fit with the roofing material used. The purpose of flashing is to ensure good drainage away from the window and to provide protection from the elements.
VELUX offers a range of flashings designed for different roofing materials and provide two options for installation height (standard and recessed).

VELUX flashing: standard or recessed installation?

Recessed installations offer a more sleek, streamlined appearance, sitting 40mm deeper in the roof structure. Recessed installations also offer greater energy efficiency, and when installed with the appropriate VELUX insulation collar actually offer a lower certified u-value, saving energy and providing architects with greater design flexibility.
