Chip-break aluminum doors and windows are currently a popular choice in home decoration, and glass, as an important component of doors and windows, its selection cannot be ignored.

When purchasing thermally-insulated aluminum doors and windows, consumers tend to pay more attention to brands, hardware, etc., but tend to ignore the configuration of glass. However, most of the door and window area is glass, and its heat insulation and sound insulation performance directly determines the overall effect of the doors and windows.

Different use environments have different requirements for glass. If you want the glass to have good heat insulation and thermal insulation effects, you can ask the merchant about the solar heat gain coefficient (SHGC) and heat transfer coefficient (k value, or U value) of the glass. The lower the SHGC value, the better the heat insulation effect of the glass; the smaller the k value, the better the thermal insulation effect. If you want the glass to have good lighting performance, you can understand its visible light transmittance. The larger the value, the better the indoor lighting effect.

The common configuration of thermally-broken aluminum doors and windows is double-layer hollow tempered glass, which is the basic configuration on the current market. There are various specifications such as 5+12a+5, 5+18a+5, 5+25a+5, 5+27a+5, etc., which can be used for different types of thermally-broken aluminum alloy windows. In addition, there is also three-layer hollow tempered glass, because it has one more layer than ordinary double-layer glass, the overall thermal insulation performance is improved, and the k value coefficient can reach 1.77.

In short, when choosing thermally-broken aluminum doors and windows, it is necessary to comprehensively consider various performance indicators according to actual needs, and pay attention to the overall quality of doors and windows to obtain a better user experience.
