The larger the wall thickness of aluminum doors and windows, the better the performance? Don't be misled anymore, this is the truth of the facts Familiar with the doors and windows of friends know to judge the quality of aluminum alloy doors and windows, need to look at from these aspects:
1. Whether the structural design of the profile is reasonable;
2. Whether the sealing and thermal insulation of doors and windows meet the standards;
3. Hardware and glass of doors and windows
What about profile thickness? What is the thickness standard of aluminum alloy doors and windows, and the national standard has specific provisions.
The wall thickness of the main stress part of the aluminum alloy window profile is not less than 1.4mm; the doors and windows above the 20-storey building can be appropriately selected to increase the thickness of the profile. The wall thickness of the main force part of the heavy sliding door profile is not less than 2.0mm, and the thickness of the swing door profile is not less than 1.2mm. In addition, a single door and window of more than 3-4 square meters can be thickened, and too large can be added to the column to increase its physical strength.
However, many people will equate the wall thickness of the profile with the product price of the doors and windows, and the thermal insulation performance of the doors and windows. They believe that the greater the wall thickness of doors and windows, the higher the price of doors and windows, in the door and window market, many merchants will also take the profile wall thickness as a product selling point, but this does not mean that the thicker the door and window wall, the better the performance of doors and windows.
Aluminum wall thickness has little effect on the thermal insulation of doors and windows: and "The larger the series, the more thermal insulation? "Same. In fact, the wall thickness of the profile has an impact on the strength and wind pressure resistance of the doors and windows, but the impact on the thermal insulation performance is very small. After all, the wall thickness of the profile is not equivalent to the profile cavity structure, and the product thickness of the aluminum alloy doors and windows is not selected according to the minimum wall thickness of the specification, but is selected according to the requirements of the door and window hole size, wind pressure value and comprehensive environment.
