At present, the noise pollution in the city is very serious. If the sound insulation of doors and windows is not good, the noise will be very loud and people will be upset seriously. In the age of noise pollution, let the Windows help you with such sound insulation. Let's take a look at the 7 key points of window sound insulation decoration to help you avoid noise pollution.
1. Stick the window sound insulation film
the sound insulation film is a multi-layer structure, and the sound insulation resin is sandwiched in the middle by polyvinyl butyral (PVB) layer. The whole intermediate film evenly distributes fine particles (heat insulation fine particles) with heat insulation effect.
When using sound insulation film in buildings, the high-performance intermediate film sandwiched between the film has visible light transmission performance, so it will not block the visible light transmission rate of buildings and keep clear sight. Window sound insulation film is relatively cheap, and the usage is the same as that of mobile phone film.
2. Install windows soundproof seal strip
soundproof seal strip, it is only effective for Windows with poor sealing, and the price is also very cheap.
Before using, make sure whether the non-soundproof is caused by the large gap of the window, otherwise it is useless to paste it. The sealing strip blocks the gap of the window, which is the same as sound insulation cotton.
3. Add a layer of ordinary plastic steel window
this method is suitable for outdoor traffic noise is not particularly serious, and if the window sill in the home is relatively wide, a layer of ordinary plastic steel window can be installed inside or outside the original window.
Plastic-steel windows should be sealed well, and the cavity distance between the two windows should be more than 10cm. The sealing performance of casement window is better than that of sliding window, so it is better to choose casement window for the installed windows. This plastic steel window is relatively low in cost.
4. Add a layer of soundproof window
soundproof window is generally composed of double-layer or three-layer glass with the same texture or different thickness of glass and window frames. The glass used will be thicker than ordinary window glass.
Some soundproof window use specially processed sound insulation layer, or there is an aluminum alloy partition frame filled with desiccant between the sound insulation layer, and the glass components are bonded with sealant at the side; some use the principle of thermos flask to make transparent and recoverable flat glass components with balanced Compression Resistance, fill the window frame with sound absorption materials, fully absorb the sound waves of transparent glass, and isolate the noise of each frequency band to the greatest extent.
However, the price of this soundproof window is usually from 800 yuan/m2 to 1300 yuan/m2, and the price with ventilation device is higher. When purchasing, consumers should ask the merchant for a test report and check the sound insulation volume to judge. In addition, it is best to agree with the merchant in the contract to achieve the sound insulation effect after installation soundproof window.
5. Refit into window soundproof window
if the window sill in the home is not wide enough, or if you think the ventilation performance of adding a layer of soundproof window is not good enough, you can also remove the original window and refit a layer of low frequency soundproof window.
At present, double-layer hollow windows are mainly used for sound insulation, which can also play a role in isolating traffic noise, but in terms of sound insulation effect, it is worse than installing a layer of soundproof window.
6. Install soundproof curtains
sound insulation curtains are equipped with inner frame on the top of the curtain box beam installed in the window, and the curtain box is equipped with a curtain rolling shaft. The curtain is rolled on the rolling shaft and extends curtain box through a joint at the bottom of the curtain box, the two sides of the opposite window are respectively equipped with one curtain, and the two sides can slide curtain chute inside respectively. The bottom panel of the window is equipped with a curtain bottom groove, curtain box the bottom joint, the two curtain chute and the inner side of the curtain bottom groove are equipped with groove sealing strips, and both are in the same plane. Through the drive of coil spring and descending cable or ascending cable and descending cable, the bottom edge of the curtain moves up and down, the winding shaft rotates in the opposite direction to lower and fold the curtain on it.
In this way, after the curtain extends out from within curtain box and passes through curtain chute, the bottom edge of the curtain enters the bottom groove of the curtain to completely close the window, so as to completely close the window with the curtain and make sound insulation. Some places like cinemas use more soundproof curtains, and the effect is also good.
7. Sound insulation glass should be chosen well
now there are mainly hollow glass, laminated glass and vacuum glass in the market. The first two prices range from over one hundred to over 700 or 800 thousand. There is no need to say more about 100 or 200 glass, and there is no guarantee for the sound insulation effect of street stalls.
The principle that vacuum glass can not transmit sound is aimed at noise of various frequencies. After installation, it can reduce noise by 30-40 decibels.
After installation, the sealing of the surrounding frame will definitely not be as big as the window when soundproof window is made. Because it can't be put in. Therefore, some small gaps will be left around the window frame. After installation, be sure to stick around the window with silicon sealant. The seal around seems simple, but it still needs professional personnel to do it perfectly.
If you want to reduce the noise effect in the most cost-effective way, you can consider sticking sound insulation film on the glass first, then sticking sealing strip on the window gap, and then changing the curtain with good sound insulation effect. The operation is simple and inexpensive.
