The sound insulation effect of our aluminum alloy doors and windows is determined by its air tightness. The higher the air tightness, the better the sound insulation effect, because the ability to stop the transfer of media is better. The factors affecting the air tightness of the door and window have the following points：
Whether the lap joint of the window and door frame sash meets the use requirements.
Whether the length of air tight waterproof glue bar and brush bar meets the requirements, whether its quality is up to the standard.
When you choose inner fan window, You should pay attention to whether the air tightness rubber strip is the same as the inferior branch of inner fan, whether the brush has lost its hair, hair down and whether the glass bar is as long as the glass.
The standard of air tightness of doors and windows can be divided into 3 grades,.Airtightness 2m3/hr.m2 Airtightness 8m3/hr.m2;; Airtightness 30m3/hr.m2 . The lower the better the gas density, the less easy the leakage of gas into the room.
The suggestion of selecting the grade of sound insulation:
1、A noisy area
The crossroads, the railroads, the airport, the market, etc. Aluminum alloy doors and windows of less than 2m3/hr.m2 air tightness grade are used in the surrounding buildings with more complex noise.
2、General area
General apartment houses, building communities, hospitals, factories, schools and other buildings can use aluminum alloy doors and windows of less than   8 m3/hr air tightness grade.
3、Quiet area
Aluminum alloy doors and windows of less than 30m3/hr.m2 air tightness grade can be used in suburban and rural residential areas in relatively quiet areas.
Home is a place for us to rest and the most relaxing place to relax. Tired for a whole day, back home, try to think about the noisy noise outside the window, how can you have a good rest? The above points are expected to help you select the right doors and windows and you will have a warm home.
