In broken bridge aluminum doors and windows, we usually use heat insulation strips as one of the materials. When choosing insulation strips, you should consider the following questions: 　　

① Reduce the heat conduction: the use of insulated broken bridge aluminum alloy profiles and hollow glass structure, the broken bridge aluminum doors and windows reduce the heat conduction through the doors and windows.　　

② Prevent condensation: The temperature of the inner surface of the broken bridge aluminum door and window profile with heat insulation strip is close to the indoor temperature, reducing the possibility of indoor moisture condensing on the surface of the profile due to oversaturation.　　

③ Energy saving: Broken bridge aluminum doors and windows with heat insulation strips can reduce one-third of the heat lost through the window frame; in summer, if it is air-conditioned, windows with heat insulation strips The frame can reduce the energy loss more.　　

④ Protect the environment: The application of the thermal insulation system for broken aluminum doors and windows can reduce energy consumption and at the same time reduce the environmental radiation generated by air conditioning and heating.　　

⑤ Good for health: The heat exchange between the human body and the environment depends on the indoor air temperature, air flow speed and outdoor air temperature. By adjusting the indoor temperature of the broken aluminum doors and windows, the temperature is lower than 12~13℃, which has reached the most comfortable environment.　　

⑥. Noise reduction: The use of hollow glass structures with different thicknesses and a cavity structure of thermally insulated aluminum bridges can effectively reduce the resonance effect of sound waves, organize sound transmission, and reduce noise by more than 30dB.　　

⑦Colorful colors: The aluminum profiles of different colors can be produced after anodic oxidation powder spraying and fluorocarbon spraying surface treatment. After rolling and combining, the insulated and broken aluminum doors and windows produce indoor and outdoor double-color windows of different colors.

Generally speaking, PVC heat insulation strips have the advantages of beautiful appearance and low price. However, due to the low strength and poor heat resistance of PVC resin, the overall strength and safety of processed insulated aluminum doors and windows cannot be guaranteed.

At present, only PA66 insulation strips can meet the performance requirements of energy-saving door and window insulation strips. This is why some broken bridge aluminum doors and windows on the market are expensive.

It is impossible to choose some cheap PVC heat insulation strips and broken bridge aluminum doors and windows. Not only did they not play a role in air tightness, water tightness, and wind pressure resistance, but also did not play a role in heat preservation, heat insulation and sound insulation. To work. If you use PVC insulation strips, it will not play the role of your wife. It can be said that it is better than nothing.
