What makes a window energy efficient

Windows and energy efficiency

Although - or precisely because you look through them every day and usually use them just as often, most people only perceive windows subconsciously. As before, however, most of the heat is usually lost through them. Leaky or outdated windows can ruin even the most sophisticated energy concept in a house. Conversely, this means: Windows offer huge savings potential if you deliberately examine them for weak points and replace outdated models with more modern ones.

Even more money can be saved if replacement or renovation measures are not planned separately but in conjunction with the entire building fabric. Sanier.de shows you how you can reliably check with simple means whether your windows are still tight. We also present the features you should pay attention to when purchasing new glasses and windows, and the connections between the heating and the windows. We also asked the managing director of the Windows and Facades Association for assessments and advice on the subject of energy efficiency. Have fun while reading!
