Soundproof window there are two choices. The first one is 75 series broken Bridge aluminum window with three layers hollow glass, the second is 70 series laminated glass. Both of them have good sound insulation effect and have been tested by many years of practice in the factory.
Three-layer hollow glass soundproof window:
the window material uses Zhongwang broken bridge aluminum 75 series Internal flat profile, the wall thickness of the profile cavity is 1.8mm, and 12 sealing structures. The glass uses 5 12a 5 12a 5 three-layer hollow glass, and the width between the glass is aluminum spacing strip 12mm.
Three-layer laminated glass soundproof window:
the window material uses Zhongwang broken bridge aluminum 70 series Internal flat profile, the wall thickness of the profile cavity is 1.8mm, and the 10-channel sealing structure. Glass uses 5 0.76PVB 5 0.76PVB 5 three-layer laminated glass, triplex glass the glue thickness of the interval is 0.76mm.
The principle of soundproof window is multi-cavity sealing, block sound transmission and prevent glass resonance. For specific selection, please determine which series of products to use after actual measurement by the designer.
