Acoustic PVB
Product Classification:
Product Introduction
Safety glass using sound insulation film can provide acoustic glass to meet most needs. In a variety of glazing, the product combines sound control with all the advantages of traditional PVB film. Even in the integral safety laminated glass, the sound insulation film shows outstanding sound control performance. Compared with float glass of the same thickness, the sound insulation film can increase the sound insulation value by 2-5 decibels.
Insulating glass can not solve the low-frequency noise, such as tire noise on the road, train sound using clamping glass can be a good solution. This is because the film in the middle of the sandwiched glass can hinder and buffer the vibration of the glass, block the noise transmission, especially the medium and low frequency noise.
