What material is good for doors and windows? At present, there are four commonly used materials for doors and windows: plastic steel, aluminum alloy, aluminum clad wood and broken bridge aluminum.
Each of them has its own advantages. Plastic steel is relatively strong and the price is the lowest among them. It is not good, but it is relatively heavy. It is easy to fall off after being installed for a long time.
Aluminum alloy is used more, the material is lighter than plastic steel, the price is medium, but the heat insulation and sound insulation effect is just so-so.
Aluminum clad wood is not easy to deform, it is better to use in the north, and it is better to protect the air tightness when the temperature is low. At the same time, it is also beautiful. But the cost is higher.
Broken Bridge aluminum now there are relatively advanced materials in the country, which can keep mixed heat insulation and sound insulation. If it is not good, the price is relatively high.
