Which is better sound insulation effect of vacuum glass or insulating glass?
Today, a customer asked which sound insulation effect of vacuum glass or insulating glass is better? If we want to clarify this problem, we must first make clear the insulating glass and vacuum glass. Now, there are few enterprises doing vacuum glass. And the price of vacuum glass should be at least 400 yuan / m2.
If it is double insulating glass, the price is about 50 per square meter more than that of single insulating glass.
The insulating glass is composed of two layers of glass with a layer of air about 9mm thick sealed in the middle. It has the function of heat preservation.
Vacuum glass is a seal between two layers of glass. The distance between the two glasses is about 1 mm. And the sealing space is vacuumed. In order to prevent atmospheric pressure from deforming the glass, there will be very small supporting points on the vacuum glass.
What kind of sound proof window is the best? What kind of sound insulation glass is used for sound insulation windows?
Nowadays, there are three kinds of sound insulation glass on the market, insulating glass, laminated glass and vacuum glass. So which kind of sound insulation glass has the best sound insulation effect? What are the advantages and disadvantages?
Insulating glass doors and windows
Insulating glass of soundproof window glass
Insulating glass was invented by Americans in 1865. It is a new building material with good heat insulation, sound insulation, beautiful appearance and application, and can reduce the self weight of buildings. It is made of two (or three) pieces of glass, using high-strength and high air tightness composite binder, and bonding the glass sheet with the aluminum alloy frame containing drying agent. In contrast, the sound insulation effect is not very good, but its heat insulation effect is beyond doubt.
Laminated glass for acoustic window glass
Laminated glass is composed of two or several pieces of float glass sandwiched with strong and tough PVB (ethylene polymer butyrate) film, which is pressed by hot press and discharged as much as possible, and then put into a high-pressure steam kettle to dissolve a small amount of residual air into the film by high temperature and high pressure. Compared with insulating glass, its sound insulation effect is still good, but compared with vacuum, there is still a certain gap, for low-frequency noise, the effect is not ideal for vacuum, but because of its price, cost performance is relatively high, is a relatively popular sound insulation glass.
Vacuum glass for soundproof window glass
Vacuum glass is a kind of two-layer glass, which is developed and manufactured by using the principle of flat thermos bottle. The interlayer of two layers of glass is vacuum with air pressure lower than 10-1pa. The inner wall is coated with low radiation film, transparent or transparent. A "support" square array is set between the two layers of glass to withstand the atmospheric pressure of about 10 tons per square meter, so as to keep the interval between the glasses and balance the compression resistance Vacuum layer of new glass products.
Vacuum glass is because it makes use of the principle that sound cannot be transmitted in vacuum, so the sound insulation effect is the best. It has good sound insulation effect for all kinds of noise frequencies. But its price is slightly higher than the laminated glass.
How to choose the appropriate sound insulation glass?
When choosing sound insulation glass, first of all, you should consider your own needs. If you live on a high floor, such as 20 floors or above, and there is no train or large trailer nearby, you can consider choosing laminated glass. The sound insulation effect is almost the same. If the floor is low and close to the road or viaduct and there are low-frequency noise sources nearby, then you should consider using vacuum glass In this way, the noise problem can be completely solved.
