At a time of rising energy costs and increasing environmental awareness, choosing the right window frames is not just a matter of aesthetics, but more importantly of real savings and year-round comfort. The right windows protect not only from the cold in winter, but also from the heat in summer. How to choose the ones that will create optimal thermal conditions in the house?

Parameters that matter
How warm your new windows will be depends on a number of U. Uw (where "w" comes from "window") is the heat transfer coefficient, which tells you how much heat escapes through the entire window. The lower the value, the better. Uw is made up of Uf (heat transfer coefficient for the window frame and Ug (heat transfer coefficient for the glass). Modern energy-efficient windows should achieve Uw at a maximum of 0.9 W/(m²K), which is in line with the requirements of the "Clean Air" program and allows you to obtain financing for thermo-modernization.

From good to best - three levels of warmth
- The Kömmerling 76 window system is a solid foundation for those looking for a proven solution at an affordable price. With an installation depth of 76 mm and a five-chamber profile structure of 76 AD and six-chamber 76 MD, it provides a Uf of 1.0 W/(m²K) and above. Combined with a triple thermal glazing package, the entire reference window achieves a Uw as low as 0.76 W/(m²K). It is an excellent choice for single-family homes, where proven quality and good thermal performance without excessive costs are a priority. The system will also prove its worth in modernized buildings, where replacing the woodwork is expected to bring measurable savings on heating.
- The Kömmerling 88 system is a true premium windowsystem and an excellent choice for those designing an energy-efficient or passive house. With an installation depth of 88 mm and seven chambers in the profile, it provides exceptional thermal insulation: Uf is only 0.93 W/(m²K), and the entire reference window can reach Uw as low as 0.71 W/(m²K). Windows on the 88 profiles will prove themselves in extreme and demanding conditions - in harsh mountain climates, in buildings with large glazing, and in passive houses, where every tenth of a watt matters.
- The WarmCore system is the absolute top of sustainable window technology. The hybrid of aluminum and PVC is the answer to the needs of green and modern architecture: slender, minimalist frames that are not inferior in performance to warm plastic systems. WarmCore achieves a Uf of 1.0 W/(m²K), and the entire window can go below 0.76 W/(m²K). It is a choice for investors who value design and modern aesthetics - large-format glazing, dark aluminum colors and industrial character - without compromising on energy savings.

Benefits that make you warmer
Choosing Kömmerling windows is an investment that will pay off for years to come. Reduction of heating costs by up to 20-30%, absence of thermal bridges ("cold zones" at the windows), better acoustic insulation and higher property value are real and tangible benefits. And if you are planning to replace your windows as part of your thermal modernization, check out the "Clean Air" program - you can get a grant that will significantly reduce the cost of your investment.
