The function of soundproof windows is also often seen in our lives. It can be said that it is an indispensable part of the living environment. Imagine if the soundproofing effect is not good, then the outdoor noise will be transmitted to the interior, which is undoubtedly a torment for the leisure or work and study in the home, and the soundproof windows effectively absorb the sound waves of the transparent glass, making the noise effective. Segregation has become a necessary building material for the family. The following small series introduces the methods of window sound insulation and soundproof windows. “ Window sound insulation method 1, converted into a window sound insulation window If the window sill in the home is not wide enough, or if it is considered that the ventilation performance of an additional soundproof window is not good enough, the original window can be removed and a low-frequency soundproof window can be modified. The double-layer hollow windows that are mainly used now are used for sound insulation. This method can also play a certain role in isolating traffic noise. However, from the perspective of sound insulation, it is worse to install a more soundproof window. 2, affixed with window sound insulation film The sound-absorbing film is a multi-layered structure sandwiched by a polyvinyl butyral (PVB) layer. The entire intermediate film uniformly distributes fine particles (thermally insulating particles) having a heat insulating effect. In the use of sound insulation film in buildings, the high performance intermediate film sandwiched in the middle of the film has visible light transmission properties, so it does not block the visible light transmittance of the building and maintain a clear line of sight. Window noise film is relatively cheap, the usage is the same as mobile phone film. 3, equipped with soundproof curtains The soundproof curtain is installed on the top of the inner frame beam installed in the window and the curtain box is installed on the top of the window. The curtain box is provided with a curtain winding shaft. The curtain rolls are wound on the package shaft and extend out of the curtain box through a slit at the bottom of the curtain box. Each of the two sides is equipped with a curtain chute in which two side edges of a curtain can slide respectively, and a bottom curtain groove is arranged on the bottom plate of the window, and a through slit at the bottom of the curtain box, two curtain chutes and The inner side of curtain bottom groove is equipped with groove sealing strips, and all in the same plane. Driven by coil springs and descending cable or rising cable and falling cable, the bottom of the curtain moves up and down, and the winding shaft is upside down The curtain that is rolled onto the package is lowered and retracted so that the curtain extends from the curtain case, passes through the curtain chute, and enters the bottom of the curtain at the bottom edge of the curtain. The window is completely closed and the window is opened with the curtain. Completely closed and soundproofed. Some areas such as movie theaters use more soundproof curtains, and the effect is also good. 4, install the window soundproof seal Soundproof seals are only valid for poorly sealed windows, and they are cheap, but make sure that no sound insulation is the cause of large window gaps. Otherwise, it is useless. The sealing strip is to block the gap in the window, and it acts like a soundproofing cotton. 5, add a layer of soundproof windows The soundproof window is generally composed of two or three layers of glass or window frames of different thickness or glass thickness. The glass used is thicker than ordinary window glass. However, the price of such soundproof windows is usually between 800 yuan/m2 and 1300 yuan/m2, and the price of ventilation windows is higher. When consumers purchase, it is best to ask the merchant for a test report and check the size of the sound insulation. In addition, it is best to contract with the merchant in the contract to achieve the sound insulation effect to be achieved after installing the soundproof window. 6, add a layer of ordinary plastic steel window This method is suitable for outdoor traffic noise is not particularly serious situation, and the sill in the home is relatively wide, you can add a layer of ordinary plastic steel window inside or outside the original window. Plastic window to choose a good seal, the distance between the two layers of the window is preferably 10 cm or more. Casement windows have better sealing than sliding windows, so it is best to choose cased windows for retrofit windows. This plastic window is relatively low in terms of cost. To reduce the noise impact in the most cost-effective way, consider putting a sound-absorbing film on the glass first, and then applying a sealing strip to the window gap, and then change the curtain with good sound insulation. The operation is simple and inexpensive. Soundproof window type 1, double vacuum Double-layer vacuum glass and double-layer hollow glass are completely different in structure and production. Double-layer hollow glass simply bonds two pieces of glass together with an air layer in between, and double-layer vacuum glass is in two pieces of glass. In the middle, the film support is sandwiched, and the two glasses are completely fused in a high-temperature vacuum environment. The middle of the two glass sheets is vacuum. Of course, the vacuum degree of the double vacuum glass cannot reach 100% vacuum, but the window is so large. There are so many emotions and bridges. These are just tiny acoustic bridges that can be ignored. In fact, the soundproof properties of vacuum glass and insulating glass are not much different. 2, double layer adhesive Double-layer laminated glass is a layer of film material sandwiched between two layers of glass. This film is the same material as the support of vacuum glass. The support of vacuum glass is negligible, and the film of laminated glass is As large as glass, that is, all support points, noise will certainly be conducted through the support, of course, if there is a good window profile, do a good job in window sealing, double laminated glass can also achieve a part of the sound insulation effect. In fact, laminated glass is mainly designed for safety. Some stations and public places use laminated glass. Editor's summary: The window sound insulation method and the type of soundproof window are introduced here, and we hope to help everyone.
