What are the advantages and disadvantages of broken aluminum doors and windows?

In recent years, many buildings have adopted thermal insulation materials, and the broken bridge aluminum doors and windows with thermal insulation strips are one of the more promising ones. In the past, the production of heat insulation strips was mostly abroad, and domestic demand was met by imports. Nowadays, through unremitting efforts, domestic production technology is becoming more and more mature. In China, the insulation strips of broken aluminum doors and windows are mostly made of PVC and PA66. According to the different production materials, the key points of broken aluminum doors and windows are also different. Let's take a look at some advantages and disadvantages of broken aluminum doors and windows!

Advantages of broken bridge aluminum doors and windows

1. Reduce heat conduction: The thermal conductivity of aluminum alloy profiles with thermal insulation and broken bridges is 1.8 ~ 3.5 W/㎡ k, which is much lower than that of ordinary aluminum alloy profiles.

2. Anti-condensation: The temperature of the inner surface of the profile with heat insulation strip is close to the indoor temperature, which reduces the possibility of dew condensation on the profile surface due to oversaturation.

3. Energy saving: In winter, the window frame with heat insulation strips can reduce 1/3 the heat lost through the window frame; In summer, if there is air conditioning, window frames with heat insulation strips can reduce energy loss to a greater extent.

4. Environmental protection: Through the application of heat insulation system, energy consumption and environmental radiation caused by air conditioning and heating can be reduced. ⊙ Good for health: The heat exchange between human body and environment depends on indoor air temperature, airflow speed and outdoor air temperature. By adjusting the indoor temperature of doors and windows not lower than 12 ~ 13℃, the most comfortable environment is achieved.

5. Noise reduction: The hollow glass structure with different thickness and the hollow structure of heat insulation broken bridge aluminum profile can effectively reduce the vibration effect of sound waves, prevent the sound from spreading and reduce the noise by more than 30dB.

6. Colorful colors: After surface treatment such as anodizing, powder spraying and fluorocarbon spraying, aluminum profiles with different colors can be produced. Indoor and outdoor double-color windows with different colors can be produced by rolling aluminum alloy doors and windows.

Disadvantages of broken bridge aluminum doors and windows

Due to the low strength and poor heat resistance of PVC resin itself, the overall strength and safety of processed aluminum doors and windows cannot be guaranteed. However, due to its low cost, it still has some low-end markets. At present, only PA66 insulation strip can meet the performance requirements of energy-saving door and window insulation strips, but its price is high. So this is also the reason why some broken aluminum doors and windows have high prices and some offer low prices.

Broken-bridge aluminum doors and windows, as a new type of thermal insulation building material, are increasingly loved by people. However, the production characteristics of broken-bridge aluminum doors and windows are quite different due to the different production materials of heat insulation strips. The use of broken aluminum doors and windows is a close combination of technology and life to a certain extent, and the progress of technology promotes the comfort of life. Broken-bridge aluminum doors and windows also have many shortcomings, but it is undeniable that the use of broken-bridge aluminum doors and windows still makes people's living conditions more comfortable to some extent, and its good thermal insulation effect enables people to feel the coolness from the house in hot summer!
