VELUX roof window GNU 0064 | top-hung/pivoting | triple glazing | PVC

The VELUX GNU 0064 polyurethane roof window allows even price-conscious customers to install an original VELUX top-hung/pivoting roof window with 3-pane insulating glazing, ensuring they don't have to miss out on the proven quality of the world's leading roof window manufacturer. In terms of value for money, the affordable VELUX GNU roof window is unbeatable. The original VELUX GNU top-hung/pivoting window consists of a wooden core encased in a seamless, waterproof polyurethane coating.

This allows the roof windows to be installed even in rooms with higher humidity, such as bathrooms and kitchens. It is also suitable for rooms where easy-care, white roof windows are preferred. The GNU roof window combines all the advantages of standard pivoting windows with a white surface that blends an elegant look with protection of the wooden core from moisture.

The GNU top-hung/pivoting window is equipped with an ergonomic handle at the bottom, which allows the sash to be opened continuously up to a 45° angle. At the top, the GNU features the proven and comfortable control bar, through which the roof window can be opened in the pivot position. Opening it as a top-hung window allows you to lean out comfortably and enjoy the beautiful panoramic view, while the pivot option allows for a 180° rotation into the cleaning position. Additionally, the proven background ventilation is integrated into the top control bar. The unique, integrated ventilation flap allows for dust- and insect-free ventilation even when the window is closed. It is very suitable for rainy days and to ensure a permanent, healthy indoor climate, allowing for air exchange without opening the window. 

VELUX ThermoTechnology™

The new generation VELUX GNU windows rely on innovative materials and advanced technologies to provide more comfort, better energy efficiency, and lower heating costs. With ThermoTechnology™, you benefit from windows that optimally protect against heat loss and improve airtightness by one class compared to the previous generation – from 3 to 4. This improvement leads to a significantly higher insulation effect, reducing energy consumption and increasing comfort in your home.

A crucial part of ThermoTechnology™ is the use of thermally modified wood in the frames and sashes of the windows. This process, where the wood is heated to over 175 °C, reduces the moisture in the wood by up to 50%, making the material more stable and insulating. This process replaces chemical treatment and makes the wood more resistant to aging and moisture. The result is a durable, resilient material with properties similar to cedar wood.

The combination of thermally treated wood and an additional layer of water-repellent polyurethane ensures excellent thermal insulation and protects against moisture, wind, and weather influences. This new technology not only contributes to reducing your heating costs but also improves energy efficiency and comfort in your attic. Look for the ThermoTechnology™ seal on VELUX products – it guarantees outstanding thermal insulation for better living quality.

Flashing

VELUX Flashing: Do I really need it?

The flashing is an indispensable element for the proper installation of a roof window into the roof surface. It channels rain and meltwater around the window and also protects it from the wind. Only with a flashing can an absolutely tight connection between the roof window and the roof be guaranteed.
Furthermore, thanks to the universal installation bracket, you have the choice between two different installation levels: standard and recessed installation.

VELUX Flashing: Standard or Recessed Installation?

With recessed installation, the window sits 40 mm deeper in the roof. This further improves the window's excellent thermal insulation properties and creates a more harmonious look on the roof. To ensure the maximum likelihood of achieving the declared energy efficiency, we recommend installing the roof window with flashing for recessed installation. Combined with the installation of the BDX 2000F insulation and connection set, this variant offers further opportunities for energy savings.
