At present, the glass configuration of bridge-cut aluminum doors and windows is mostly double-layer insulated tempered glass , and the sound insulation effect is already very good . However there are three layers of insulated glass now, is it necessary to extend or superfluous the function of the three-layer insulating glass as compared with the double-layered insulated glass?

bridge-cut aluminum doors and windows are basically configured with 5+9+5 or 5+12+5 hollow glass, which is a 9mm or 12mm air gap between two layers of 5mm glass, because the conductivity of glass and air is not the same. , In order to play the role of insulation, sound insulation.

In the case of a three-layer hollow glass, such as 5+6A+5+6A+5, the thickness of the intermediate air layer increases, and a layer of glass is added. The quality of the soundproofing of glass mainly depends on the space thickness of the air layer of the insulating glass. The greater the thickness of the air layer, the better the sound insulation effect.
