The opinion Campi
This sound insulation gives absolutely stunning results. The resonance that we hear in commercial vehicles is linked to the vibration of the sheet metal. This sound insulation prevents the sheet metal from vibrating. Sound propagation is thus blocked (incoming sounds and outgoing sounds). To be paired with thermal insulation and trim for maximum comfort. We highly recommend. Price pose included.
