From the point of view of noise control, the greater the thickness of the air layer of insulating glass, the better the noise control effect. If the thickness of the air layer is less than 6mm, its insulation volume is only slightly higher than that of a single piece of glass of the same thickness. Under normal circumstances, the thickness of the insulating glass air layer is commonly used in two specifications: 9mm and 12mm; In special cases, it can be stretched to 20~100mm.
The cavity of this configuration is too large, and if it is well sealed, the sound insulation effect will be good. Sound insulation first depends on the glass configuration, toughened glass sound insulation effect is better, followed by the cavity to flush argon, which can enhance the sound insulation effect
