Nowadays people usually live in buildings. The neighbors of the building are short and relatively close. Sometimes they can hear and talk, so we need to install soundproofing to avoid these phenomena, especially if our windows are most in need of sound insulation, then What should I do if the windows are not soundproof ? What are the shopping tips for window soundproofing materials? If you need to know, just take a look at the small series of the decoration home network.
First, how to do if the window is not soundproof
1. Window sound insulation film
The sound-insulating film has a multi-layer structure in which a sound-insulating resin is sandwiched by a polyvinyl butyral (PVB) layer, and the entire intermediate film uniformly distributes fine particles (insulating fine particles) having a heat insulating effect. When a sound-insulating film is used in a building, the high-performance interlayer film sandwiched between the films has visible light transmission properties, so that it does not block the visible light transmittance of the building and maintain a clear line of sight. Compared with the window film, the usage is the same as that of the mobile phone film.
2. Use acoustic glass
The sound-proof glass has hollow glass, laminated glass and vacuum glass. Most professional soundproof windows use laminated glass and vacuum glass. Vacuum glass uses the principle that vacuum cannot propagate sound, and it is aimed at noise of various frequencies. If the house is very noisy, vacuum glass or composite three-layer acoustic glass can be used, and the sound insulation effect is good. If the noise is not too big, the choice of insulating glass or laminated glass is almost the same.
3. Sound insulation strip for window sound insulation
The domestic window frame is generally equipped with rubber sound insulation strips or wool sound insulation strips, but the wool sound insulation strips are not strong, and it is easy to remove hair after a long time. The rubber is easy to harden and age after being used for a long time. The foreign window sound insulation strip is made of leather material, which is filled with sound-absorbing cotton, so that it maintains toughness and is not easy to age, which ensures the sealing of the window.
Second, window sound insulation materials purchase skills
1. Most of the developers choose rubber sound insulation strips or wool sound insulation strips, but the wool sound insulation strips are easy to remove hair after a long time. The rubber has been used for a long time, and the capacity of the wind and sun and rain has become hard and aging, so the sound insulation strips must Anti-aging must maintain toughness. At present, there is an imported sound-insulating strip on the market, which is wrapped with cortex material. The sound-absorbing cotton is used inside, which can maintain the toughness and is not easy to aging, and the sealing of the window frame leakage problem is well ensured.
2. Nowadays, there are mainly hollow glass, laminated glass and vacuum glass on the market. If the building is more than 20 floors, and there are no trains, large trailers, etc., you can consider the choice of insulating glass or laminated glass; if the floor is low, there are roads or viaducts, and there are low-frequency noise sources, then vacuum glass should be considered. This will completely solve the noise problem. (The vacuum glass uses the principle that vacuum cannot propagate sound. After installation, it can reduce noise by 30-40 dB.)
The windows are installed in every building. For the living buildings, the windows are required to be soundproofed. If the windows are not soundproof, what are the purchase techniques and soundproofing materials? I think everyone knows through the introduction of the above small series. Well, if you still want to know more about decoration, please continue to pay attention to the decoration home Internet cafe.
The led smart flood light is made of aluminum alloy die-casting and electrostatic spraying surface treatment. The lamp head is made of tempered glass, which is safe, high temperature resistance, high strength and good light transmission.
The sealing strip is an anti-corrosion silicone rubber sealing strip, which has good sealing performance and is suitable for waterproof and dustproof applications. You can control the color change of the smart led outdoor flood light through a mobile phone to achieve all color spectrums and be used in various places. Due to its convenience and full spectrum lighting, rgb Led Flood Light can be used as led smart flood outdoor for Christmas, Halloween lights festivals.
