What Should Be Noticed in the Sound - insulation Design of Doors and Windows
1. Glass Selection
Glass is the most significant factor that affects the sound - insulation performance of the whole window. To achieve a better sound - insulation effect of the whole window:
(1) Thicker Glass
The thickness of the glass panel itself. For example, the sound - insulation performance of the insulating glass with a physical structure of 8 + 12A + 8 is better than that of 5 + 12A + 5, and 5 + 12A + 5 + 12A + 5 is better than 5 + 12A + 5.
(2) Selection of Laminated Glass
Laminated glass is a composite glass product in which two or more pieces of glass have one or more layers of organic polymer interlayer film sandwiched between them. After a special high - temperature pre - compression (or vacuum - extraction) and high - temperature and high - pressure processes, the glass and the interlayer film are permanently bonded together. The organic film among them can effectively suppress the vibration of the glass, thus effectively improving the sound - insulation performance of the glass.
