To a friend to say that under the sound of the glass how to choose it?
Laminated glass: laminated glass laminated glass structure is a safe glass production process, also known as laminated glass, can be two layers together, it can be multi-layer together. Some laminated glass sun will dry for a long time later, this is because the use of wet folder method, so used in architectural glass laminated glass are generally used dry folder method, so you can avoid sandwich.
Vacuum glass: because the vacuum glass between the two layers of glass was drawn into near vacuum, so with thermal resistance (Note 3) high characteristics, is a good insulation products, which is the original intention of the design of vacuum glass, with the insulation performance is hollow Glass is hard to compare. In the sound insulation performance of vacuum glass is also better than hollow glass.
Hollow glass: hollow glass in the high frequency noise (such as people speak the sound, the school tweeter horn sound, etc.) have good sound insulation effect, but the traffic low frequency noise (such as bus engine noise, train noise, aircraft noise, etc.) effect is not obvious The
