SOUND-INSULATING GLAZING UNITS

Sound-insulating glazing units reduce city and traffic noise. The most economical way of sound insulation is to use asymmetric glazing in the glazing packet.

For better sound insulation, it is recommended to use laminated glass packets with a special sound insulation film. At the same time, the laminated glass with sound insulation film provides a safety function for the glazing packet.
