Passive House Roof Windows

We are introducing GGU 008230, which is ideal for situations where Passive House-certified building components are required. This is the first and only roof window on the market certified for Passive House building constructions in cold climate regions*.

This roof window consists of a triple outer-glazing plus an additional inner double-glazing. The roof window itself has a Uw 0,51 W/(m2K) (EN ISO 12567-2), which is the best on the market.

The roof window is powered by the sun. For increased comfort, solar-powered shutters or awning blinds can be added. Our unique touch-screen control pad lets you operate the complete solution in a convenient and intuitive way.

In the VELUX organization we believe in sustainable living. Utilizing the power from the sun to open and close the roof window is one way. Another is letting the warmth from the sun in and keeping it there, making the roof window an energy contributor.
