Passive windows. What are the benefits?

In connection with the rise in price of energy resources, more and more attention is paid to the construction of passive houses. According to calculations, investments in a passive house pay off in the first 10 years. Therefore, more and more customers are interested in windows for a passive house. Such windows are characterized by a high level of thermal resistance, i.e. The rate of heat loss is much less than that of conventional windows. In order to reduce heating costs once and for all, passive windows can be installed both during new construction and renovation.
Passive windows provide maximum heat, wind and sound insulation.
Suppose you are faced with the task of glazing (designing) a passive house.
Therefore, you should get the maximum energy-saving characteristics of windows. I.e. High coefficient of resistance to heat transfer (or, if desired, thermal conductivity) in a certain range of values.
Of course, the characteristics of the windows for a passive house will depend on the climatic zone in which you will build it and what energy efficiency indicators other systems in your house have.
But in any case, whether it will be a passive house or it will simply be the most energy-efficient house with extraordinary indicators of energy conservation it is important to understand that the performance of each window on different projects will have significant differences.
Please note that designing a passive house is the business of narrow-profile designers like And the information specified in this article is a basic fact-finding character.

1. The energy efficiency indicators are influenced by the size of your windows and how much space the profile share and the glass unit share occupy in them. The smaller the window is, the more space the profile occupies in it, the more it reduces the thermal characteristics of your windows. This suggests that energy-efficient double-glazed windows are now much warmer than any, even the warmest profiles. Therefore, the larger the proportion in the window of an energy-saving double-glazed window, the stronger it will store heat.

2. Positioning the window in the opening can also affect the ability of the window to save heat (or lose it). Incorrect continuation of the window in the opening can lead to unwanted cold bridges, and in the worst case, condensation and fungus.

3. The organization of junctions should provide a steam-wind and waterproofing.
Now we will consider in the context of using special configurations of the most warm windows.
As already mentioned, the characteristics of windows are affected not only by the materials from which they are made, but also by the size and area occupied by the profile or glass.

Thus, we see that, firstly, all the windows in the described comparisons have unique thermal characteristics, which depend not only on the presence of cool and warm materials in them, but also on the configuration. Well, also from many, many parameters.

All these factors are important and each of them should be professionally selected for your personal project with unique characteristics.
