What's the difference between broken aluminum doors and windows and ordinary aluminum doors and windows?

Different heat insulation, different sound insulation effect, different hardness and different sealing performance.

The heat insulation effect is different. Many people install ordinary aluminum alloy doors and windows at home, and they will find that the sun shines directly in summer, and the surface temperature of aluminum alloy doors and windows is relatively high. Mainly because aluminum alloy is made of metal, which has good thermal conductivity, can dissipate heat and improve indoor temperature, so you will find that the temperature is relatively high.
