“Heat window” – how much money it actually saves?
The concept of “heat window” has figurative meaning because it does not, in fact, provide heat. The principle of energy efficient window is that it let heat pass to the apartment 2,5 times less: in winter, from the inside to the street, and in summer – vice versa. This characteristic is one of the basic ones and is defined by R coefficient. The higher this coefficient gets, less heat will pass out of the windows in the winter and you will have to turn on the air conditioning less often.
Double-glazing is the boss
Window – is a complex product, consisting of the frame, double pane, and window hardware.
Double pane or double-glazing is the most responsible for energy efficiency because it takes 75-85% of window space. Special energy efficient layer is sprayed precisely on the glass, which will keep the heat, and the panes between the glasses, filled with gas or air, will reduce heat transfer. There should be two such layers, on the external and internal glass, and, respectively two panes filled with argon.
Quick tip: always check if your double pane is the same in your contract that was in your estimate.
If your windows are highly exposed to the sun, and you suffer from extreme heat during summer, think about sun protection and multi-functional double glazing.
