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 in class A for Passive House building constructions in cold climate regions* as shown in the geographical map above.
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.
* requires flush installation with either EDJ 2000 or EDN 2000 flashings.
