2. Whether the length of air tight waterproof rubber strip and brush strip meets the use requirements and whether their quality meets the standard

3. When purchasing the inner window, you should pay attention to whether the air tight rubber strip is the same length as the lower branch of the inner window, whether the brush strip is hairless and inverted, and whether the glass batten is the same length as the glass

the standard for the air tightness of doors and windows can be divided into three levels, with an air tightness of 2m3/hr. M2 air tightness 8m3/hr. m2 ; Air tightness 30m3/hr. M2, the lower the air tightness value, the better, which means that it is less likely to leak gas into the room

intersections, railway sides, airports, markets, etc. the surrounding buildings with complex noise adopt the air tightness level of 2m3/hr. Aluminum alloy doors and windows less than m2

3. Quiet areas

the air tightness grade of 30m3/hr can be used in suburban and rural residential areas where it is quiet. Aluminum alloy doors and windows less than m2
