Optoglas insulates 30% better than similar thermal windows and has a better U-value (2.2) than a 2-layer thermal pane. By using special neutral energy glass, a U-value of 1.7 is achieved – equivalent to a 3-layer thermal pane (DS 418).

We have extensive experience in restoration craftsmanship and offer both guidance and installation of Optoglas on your existing windows.

Optoglass improves the indoor climate while reducing outside noise, making your property more comfortable.
