The most important thing is to suit yourself. The southern region does not have to pursue system doors and windows. In the northern region, aluminum-clad wood doors and windows can be considered.
For high-rise coastal areas, consider wind resistance: three glass and two cavities.
The road school considers the sound insulation capability: angle glass, triple glass and two cavities.
The furnace city considers the thermal insulation capacity: thermal insulation strip brand and width, LOW-E glass.
Consider the thermal insulation capacity in cold areas: LOW-E glass, wall thickness, sealing performance, it is better to have a test report.
The landscape community considers the viewing ability: ultra-white glass, frame window design.
