Because the door and window are not soundproof, the main reason is the problem of the tightness of the window frame and the sash itself, and the thickness of the glass. Therefore, you must transform your door and window into soundproof windows and doors.
Is all the windows soundproof?
Yes. It is only the size of the sound insulation. The sound insulation of ordinary doors and windows is below 10 decibels, and there is basically no energy saving effect. The soundproofing of the soundproof window is 1 to 2 times that of the ordinary door and window, and the energy saving is more than 50%, and it is cheap and inexpensive; this is why the soundproof window is used.
Living on the highway/viaduct/railway, why are there “noise†when closing doors and windows?
Because the main reason why the doors and windows are not soundproof is in the glass, because the penetrating power of the sound waves is very strong, especially in the case of the "highway" sound energy, the ordinary single-layer glass or insulating glass is more "powerless". ". Therefore, you must replace your glass with soundproof glass, preferably vacuum soundproof glass. Secondly, the tightness of the window frame and the window sash is not good, and the sound leakage problem is serious. It is necessary to replace the high quality sound insulation strip.
Which sound insulation effect is better for "vacuum" soundproof glass and "hollow" glass?
Vacuum sound-insulating glass and hollow sound-insulating glass are also "double-layer" glass: vacuum glass is the principle of "warm bottle". Two pieces of glass are sealed around, and the gap is "vacuum-vacuum" to seal the exhaust port to form a "vacuum layer". Air is the best medium for sound transmission. Vacuum glass is equivalent to “cutting off†the path of sound transmission. The hollow sound-proof glass does not take out the air, and the medium is still there, but the noise can also be reduced by the consumption of double-glazed glass. If you add a hollow soundproof window inside the original window, the sound insulation effect is better. But even though the noise has dropped, the sound can still be heard clearly because its principle is "consumption of noise."
Why can traditional aluminum alloy windows be directly modified with vacuum glass?
The thickness of the glass of the aluminum alloy window is 5mm, plus the gap of 3--4mm on each side, a total of 11--13mm cavity, and the vacuum soundproof glass is only 6-10mm thick, the existing residential window frame is intact. Replace the original glass to install.
Why do you have to install noise barriers when installing soundproof windows?
Ordinary windows, especially sliding windows, have the most serious leaks. Simply replace the soundproof strips, and the noise can be reduced by 3-5 decibels (compared before and after the same pilot installation in the room, the noise reduction of 3 decibels means that the potential energy of the sound has been reduced by half) .
What is the principle of sound insulation strip sound insulation?
The sound is also a wave that travels forward like a wave of water. It is driven by sound energy. The soundproof strip contains special soundproof cotton, which can consume the sound energy to the utmost extent. The sound insulation performance of the sound insulation strip is not possible for the top and rubber strips. Realized.
Why add noise ventilators?
Air pollution is very harmful. In areas with high noise, the air is not circulated after closing the window. It is easy to cause various diseases, which seriously threaten people's health. The ordinary ventilator does not close the window, and the soundproof ventilator guarantees the sound insulation capacity. After the window, there is fresh air all year round; more air purification function, also suitable for renovated customers.
