CET’s high quality acoustic laminated glass offers excellent noise reduction without compromising on light transmittance or impact performance. Acoustic laminated glass improves performance by combining various thicknesses of glass with a special acoustic interlayer.
Our high quality acoustic laminated glass can be combined with other products to provide additional benefits, such as thermal insulation and/or solar control.
Incorporating noise insulation into buildings has become a major consideration because of increased road and air traffic noise. Glazing and windows can play an important part in reducing noise pollution.
Glass controls noise by both reflecting the sound back towards the source and absorbing the noise energy within the glass. We can improve the sound insulation of glass in various ways.
Noise insulation can be improved in double glazed windows by:
- Using thicker glass.
- Differing the thicknesses of the two glass panes (isometric glazing).
- Using an efficient insulating window frame.
- Using specially-laminated acoustic glass.
The highest noise insulation is achieved by using an acoustic laminated glass.
Acoustic glass consists of a polyvinylbutyral (PVB) interlayer sandwiched between the panes of glass, heat or pressure bonded together. The acoustic interlayer is soft and acts as a noise damper, weakening the energy of the sound waves as they travel through the glass.
Triple glazing can also sometimes reduce noise depending on the air space and type of glass used. If you need further advice, please contact our Technical Department who will be pleased to help.
