All the doors and windows of the real energy-saving system are not only the use of broken aluminum profiles or the use of Low-E insulating glass energy-saving materials, but also the perfect combination of a system and the comprehensive results of the performance of each link. Three factors should be considered to measure whether building doors and windows are energy-saving, namely, heat convection, heat conduction and heat radiation. First, heat convection is the circulating flow of hot and cold air through the gap between doors and windows, and heat exchange is caused by gas convection, which leads to heat loss; second, heat conduction is the heat transfer carried out by the molecular movement of the materials used in doors and windows, which is transferred to the other side through one side of the materials themselves, which leads to heat loss; third, radiation is mainly transmitted directly in the form of rays, which leads to energy loss.

so how to choose the system doors and windows?

1. Select the correct hardware

Hardware can be said to be the soul of the doors and windows of the whole system, so that the doors and windows can exert the greatest practicality and beauty, including the combination of handles, hinges and auxiliary parts. The doors and windows of the system can be optimized to design the linkage of all parts, so that the doors and windows are "alive" and more beautiful and humanized. The hardware used for the doors and windows of Xin Sheng Yuan is imported from Sigilia, Germany.

2. Select the correct glass

Glass occupies most of the area of the system doors and windows, which is related to the sound insulation, collision avoidance and compression resistance of the system doors and windows. If the glass material is not good, the heat insulation and sound insulation are poor. There will be unnecessary cost of living. Xin Sheng Yuan doors and windows are made of hollow tempered glass, which has better heat preservation, sound insulation and noise reduction effects.

3. Correct installation

Installation is also very important. Even if the doors and windows of the system are of good quality, there will be security risks if the chain is broken in installation. It is not uncommon for high-altitude doors and windows to fall, among which improper installation is the main reason.

4. Select the correct adhesive tape

After some system doors and windows are installed for a period of time, it will be found that the wind creaks and water will accumulate in rainy days. This is actually a problem with the sealing strip. After a long period of wind, rain and sunshine, the inferior strip is easy to age, corrode and fall off, which affects the sealing performance of doors and windows. EPDM sealing strip should be used as the sealing strip.
