As the quality of life and living standards continue to improve, people's requirements for the living environment have also been strengthened, so the concern for the air quality and noise pollution around the place of residence is also increasing. In order to cope with the complicated sound of the neighborhood and the roar of factory machines 24 hours a day, more and more users will add a layer of soundproof windows when installing windows. For soundproof windows, we understand that it is a layer of glass that can isolate the sound or reduce the noise. Now we will come together to understand what is soundproof windows and the installation of which matters should be noted.
Adding soundproof windows-What are soundproof windows?
Soundproof windows by double or triple with the same texture or glass of different thicknesses of glass and window frames, the use of specially processed acoustic layer, the acoustic layer of glass used in the folder PVB film by the high temperature and high pressure firmly bonded into the acoustic layer of glass; or in the acoustic layer between the folder filled with desiccant (molecular sieve) aluminum alloy spacer, and then the side of the sealant (butyl glue, polysulfide glue, structural adhesive), the edge of the sealant (butyl glue, structural adhesive), the sound of the window is the sound of the window, the sound of the window is a very good, Polysulfide adhesive, structural adhesive) bonding synthetic glass components.
Adding soundproof windows-adding soundproof windows notes
1, ask for sound insulation test report
To the manufacturer to have a qualification unit to test the sound insulation test report, the Beijing testing units are mainly the Ministry of Construction Building Physics Inspection Center, Tsinghua University Building Physics Environmental Monitoring Center, Beijing Labor Protection Research Institute, Beijing Door and Window Hardware Testing Center and so on. The Beijing Municipal Door and Window Hardware Testing Center. Understand the sound insulation of doors and windows, according to their own economic conditions and practical needs, generally the higher the sound insulation, the higher the price of sound insulation windows, but the sound insulation should not be less than 30dB. If you are in the environment of serious noise pollution or high indoor environmental requirements, you should also pay attention to the low-frequency sound insulation of windows and doors and the lowest frequency of the sound insulation, because the energy of the traffic noise is concentrated in the low-frequency, low-frequency sound insulation of windows and doors is the weakest link, which will inevitably be the most important factor in the sound isolation of the windows and doors. The weakest link, is bound to cause low-frequency sound leakage, and ultimately will affect the sound insulation effect.
2, pay attention to the structure
Recently, some manufacturers on the market in order to improve the sound insulation of windows and doors and the use of three-layer glass and two-layer cavity process, the sound insulation by the test to improve the sound insulation is not obvious, Tsinghua University, director of the Center for Physical Environment Testing Yan Xiang teacher believes that the hollow glass sound insulation to have sufficient mass density and a larger air insulation layer, if the mass density remains unchanged, the air insulation layer change will certainly affect its sound insulation. The increase of the third glass interferes with the insulating glass cavity air sound insulation performance, sound insulation on the contrary has decreased, it is recommended to choose the sound insulation window should not be used in this process.
3, pay attention to the sealing tape
Sealing tape good or bad directly affects the sound insulation of the window, sealing tape should choose soft and flexible anti-aging materials, but the sealing tape function is sealed, the window does not leak relying on the tape to improve the window's acoustic insulation is not possible. In order to prevent acoustic window leakage due to gaps in the window sealing tape should be a closed, four corners should not leave gaps, if there are gaps will also cause sound leakage.
4, pay attention to the external wall materials
Solve the sound insulation of the living room noise reduction doors and windows of the sound insulation for the indoor acoustic environment is very important, but the materials used in the external wall, the thickness can not be ignored, because the material of the external wall, the thickness of the wall will have a direct impact on the wall of the sound insulation. If your wall sound insulation is not enough, only the installation of soundproof windows will not be good. Therefore, the wall should also be sound insulation treatment, such as railroad lines, airports around the living room, the choice of sound insulation window should pay attention to the sound insulation amount of more than 40dB, the lowest sound insulation frequency of the sound insulation amount is not less than 35dB, the use of double-layer sound insulation window, the outer window downward spiral, the inner window is open. This structure sound insulation can reach more than 50dB, and the sound environment of the living room will be greatly improved after treatment. Wall sound insulation monitoring and processing Tsinghua University Building Physical Environment Monitoring Center has accumulated a lot of experience after years of research.
Soundproof windows can be said to have been more and more widely used in home improvement now, but we must be clear before the installation of a point, the price of installing soundproof windows is relatively speaking, the cost is still relatively high. So we decided to install, we must look for the relevant formal company to consult, and check whether it has the appropriate qualification certificate, and do not act recklessly, so that in the end no half effect. The above also mentioned to us, if you want to install soundproof windows, be sure to consult the above notes, hope you can give you a little reference role.
