Sound insulation of a vacuum insulated window.

　　Vacuum insulation window by double layer or three layer with the quality of a material or glass of different thickness of glass and window frame, use the special processing of sound insulation layer, sound insulation layer glass using a clip of PVB film by high temperature and high pressure solid glue them into a sound insulation layer of the glass; Or between the sound insulation layer, the clip has the aluminum alloy frame with the desiccant (molecular sieve), and the side part reuses sealant (butyl glue, polysulfide, structural glue) to adhere to the synthetic glass components; The other is to use the thermos bottle principle to make a transparent, light, balanced, pressure-resistant plate glass component. The vacuum insulation window effectively inhibits the "dovetail effect" and the formation of the sound isolation trough, fills the sound absorbing material in the window frame, fully absorbs the sound waves of the transparent glass, and isolates the noise of each frequency band to the maximum extent.

　　Introduction of hollow sound insulation window.

　　Hollow sound insulation window is a hollow sound insulation glass + import sound insulation sealing strip, conch and added to the national standard window frame specially. Article hollow sound insulation window in empty sound insulation can reduce 15 decibels of noise, generally can reach 50 db below the sound insulation effect. The noise is not large enough and is applicable without low frequency noise.

　　In between the soundproof layer, there are aluminum alloy spacers filled with desiccant (molecular sieve), and the side part is used to glue the glass components together with sealant (butyl glue, polysulfide and structural glue).

　　The performance of the hollow sound insulation window.

　　Noise insulation: generally can reduce noise of 15 decibels, the noise is small and does not have low frequency noise.

　　Optical properties: normal visible light transmittance ranges from 10-50% and reflectivity of 13-25%.

　　Thermal properties: can effectively reduce the heat transfer coefficient U value.

　　Sealing: the aluminum spacer frame adopts automatic bending technology to take shape and minimize the connection. Use butyl glue and polysulfide or structural glue double seal to ensure the sealing and prolong its service life.

　　Thermal properties: can effectively reduce the heat transfer coefficient U value. Can reduce sunlight transmission, reduce air-conditioning cost, save energy.
