Kömmerling window systems have been tested and proven to perform in all kinds of extreme conditions.

One test took place at 2,300 metres above sea level with windows exposed for fifteen years to strong UV-radiation, freezing temperatures and heavy storms.
From windows to glazing seals, everything proved to be in the same condition at the end of the test period and still performing effortlessly.

Up to 90% of heat can be lost through windows in modern homes. Replacing your inefficient windows with high performance double-glazing windows will help you to make huge savings on your heating bills. Not only will they reduce the amount of heat lost, but also low-emissive glass allows the suns heat and light to pass through the window more easily without letting it escape back out so your home will be naturally warmer too.
