Cold air and low temperature are standard in winter! When the outdoor weather is very extreme, doors and windows become an important line of defense to protect the warmth of the interior. Do you know?
Sealant strips
The thermal insulation performance of doors and windows is closely related to the overall sealing of doors and windows, and the difference between the sealing of doors and windows depends on the quality of the rubber strip and the number of sealing channels (usually the thermal insulation effect of three seals will be better than that of two) and whether there is an isothermal line (or plane) inside the profile. When the cold and hot air exchange inside and outside the doors and windows, the two broken bridges are in the same straight line, which is more conducive to forming an effective cold-hot bridge barrier, which can reduce the cold and heat conduction of the air and reduce unnecessary heat loss.
Heat insulation strips
The core difference between broken bridges and non-broken bridge windows is the insulated strip. As an important part of the energy saving of doors and windows, the quality of the heat insulation strip not only determines the thermal insulation effect of the aluminum alloy doors and windows, but also determines the application experience of the doors and windows.
Many people take it for granted that the higher the value of the window series, the better the thermal insulation effect. In fact, it is not, the larger the series, the more insulation is only relative, only the wider the insulation bar, the better the insulation effect of the whole window is absolute!
glass
The glass area on the doors and windows accounts for about 65 - 75% of the door and window area, or even higher, so the role of glass on the insulation performance of the whole window is also increasing. In order to improve the insulation of the whole window, it is matched on the doors and windows in the glass types such as insulating glass, three-glass two-chamber, Low-e insulating glass, Low-e three-glass two-chamber to enhance the overall thermal insulation effect.
Profile cavity filling
Profile cavity structure filling insulation material (sponge or styrofoam) can also improve the overall thermal insulation performance of doors and windows. The principle is to fill the cavity between the glass and the profile, the heat insulation strip and the insulation strip, reducing the exchange rate of hot and cold air between the chambers.
