A quiet environment is very important for us. However, with more and more cars on the road and more and more construction sites, the noise also comes along, which is very disturbing. So it's very important to add sound insulation to windows? So, how does aluminum alloy window sound insulation? What are the methods of sound insulation?

1. Window sound insulation method: paste the window sound insulation film

The sound insulation film is multi-layer structure, and the sound insulation resin is sandwiched in the middle by polyvinyl butyral (PVB) layer. Particles with heat insulation effect are evenly distributed in the whole intermediate film. When the sound insulation membrane is used in buildings, the high-performance intermediate film sandwiched between the membrane has visible light transmission performance, so it will not block the visible light transmission rate of the building and maintain a clear line of sight. The window sound insulation film is cheaper, and the use is the same as the mobile phone film.

2. Window sound insulation method: install the window sound insulation sealing strip

The sound insulation sealing strip is only effective for windows with poor sealing, and the price is very cheap. However, it is necessary to determine whether the reason for the large gap of the window is not sound insulation. Otherwise, it is useless to stick it. Sealing strip is to block the gap of the window, and the role of sound insulation cotton is the same.

3. Window sound insulation method: 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 of the home is relatively wide, a layer of ordinary plastic steel window can be installed inside or outside the original window. Plastic steel windows to choose good sealing, the best distance between the two windows in the cavity 10 cm above. The sealing of casement window is better than that of sliding window, so it is better to select casement window for adding window. This kind of plastic steel window is relatively low in cost.

4. Window sound insulation method: add a layer of sound insulation window

Soundproof window is generally composed of two or three layers of homogeneous or different thickness glass and window frame, the glass used will be thicker than ordinary window glass. Some sound insulation windows are made of specially processed sound insulation layer, or aluminum alloy partition frame filled with desiccant is sandwiched between the sound insulation layers, and the edge is bonded with sealant; some are made of transparent and daylighting flat glass components with balanced compression resistance based on the principle of thermos bottle, and the window frame is filled with sound absorption materials to fully absorb the sound wave of transparent glass The noise of each frequency band is isolated. However, the price of this kind of sound insulation window is usually 800 yuan / m2 ~ 1300 yuan / m2, and the price with ventilation device is higher. Consumers in the purchase, it is best to ask for a test report from the business, to see the size of the sound insulation to judge. In addition, it is better to agree with the business in the contract to achieve the sound insulation effect after the installation of sound insulation windows.

5. Window sound insulation method: refit into window sound insulation window

If the windowsill in your home is not wide enough, or you feel that adding a layer of sound insulation window is not good enough for ventilation, you can also remove the original window and refit it with a layer of low-frequency sound insulation window. Now the main use of double-layer hollow windows for sound insulation, this way can also play a certain role in isolating traffic noise, but in terms of sound insulation effect, it is worse than adding a layer of sound insulation windows.

6. Window sound insulation method: install sound insulation curtain

The curtain box is installed on the top of the inner frame beam installed in the window, and the curtain box is installed in the curtain box, and the curtain box is stretched out through a through seam at the bottom of the curtain box. Two sides of the opposite window are respectively equipped with a curtain chute in which the two sides of the curtain can slide respectively, and a curtain groove is installed on the bottom board of the window Groove sealing strips are installed on the through seam at the bottom, the two curtain chute and the inner surface of the curtain bottom groove, which are all in the same plane. Driven by the coil spring and the falling cable or the rising and falling cable, the bottom edge of the curtain moves up and down, and the rolling shaft rotates in the positive and negative directions, so that the curtain which is rolled up and down can be lowered and retracted The bottom edge of the curtain enters into the bottom groove of the curtain to completely close the window, so that the window can be completely closed with the curtain for sound insulation. Like the cinema and other places with sound insulation curtain more, and the effect is good.
