Can be sure to tell you can. Single-layer glass and double-layer glass and the pressure is not the same, for some of the glass can be combined with a layer of glass can be, and the previous glass can also be used, between the two layers of glass open
It can be replaced by a hollow glass into it
Of course you can change the glass bar on it. Sound insulation effect in general, will be better. High frequency noise is effective.
