How to install soundproof window (sound insulation glass)?

Windows are necessary channels for indoor and outdoor air circulation, and of course they are also channels for noise transmission. In order to have a quiet home environment, the sound insulation effect of windows must be guaranteed.

Method 1: Use soundproof curtains; If the window can't be replaced, it is recommended to replace it with soundproof curtains, which will be better. If the curtain is closed, it will be much quieter than if it is not closed, which proves that it is the effect of soundproof curtain.

Method 2: change the glass; If you can change the glass, you can choose double laminated glass. With good window profiles and well-sealed window joints, double-layer laminated glass can often achieve better sound insulation effect.

Method 3: refit it into a window soundproof window; If the window sill at home is not wide enough, or the ventilation performance of adding a layer of soundproof window is not good enough, the original window can be removed and a layer of low-frequency soundproof window can be modified. At present, double-layer hollow window is mainly used for sound insulation, which can also isolate traffic noise to a certain extent, but in terms of sound insulation effect, it is worse than adding a layer of sound insulation window.

Method 4: Stick the window sound insulation film; The sound insulation film has a multilayer structure, and the sound insulation resin is sandwiched between polyvinyl butyral (PVB) layers. Particles with heat insulation effect (heat insulation particles) are evenly distributed throughout the intermediate film. When the sound insulation film is used in the building, the high-performance intermediate film sandwiched between the films has visible light transmittance, so it will not block the visible light transmittance of the building and maintain a clear line of sight. Window sound insulation film is cheaper, and it is used in the same way as mobile phone film.

Method 5: Install the window soundproof sealing strip; The soundproof sealing strip is only effective for windows with poor sealing, and the price is also very cheap. However, it is necessary to determine whether the lack of sound insulation is caused by the large gap in the window, otherwise it will be useless to post it. Sealing strips are used to plug gaps in windows, just like sound insulation cotton.

Method 6: add a layer of sound insulation window; Acoustical windows are generally composed of two or three layers of glass and window frames with different thicknesses, and the glass used will be thicker than ordinary window glass. 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 consumers buy, it is best to ask the merchant for the test report and check the sound insulation to judge. In addition, it is best to agree with the merchant in the contract on the sound insulation effect to be achieved after installing the sound insulation window.

Method 7: 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 at 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 well sealed, and the cavity distance between the two windows should be above 10 cm. The sealing performance of casement window is better than that of sliding window, so it is best to choose casement window for additional window. This kind of plastic steel window

In terms of cost, it is relatively low. If you want to reduce the noise impact in the most cost-effective way, you can consider sticking a sound insulation film on the glass first, then sticking a sealing strip on the window gap, and then changing a curtain with good sound insulation effect. Simple operation and low price.
