Multilayer material for car noise insulation. Combines sound absorption and soundproofing properties. The sound-absorbing layer of foam polypropylene does not absorb moisture into its volume, and the mastic adhesive layer is resistant to water. Qattara can be used even on areas where moisture is present periodically without the risk of drying out and peeling. The combination of layers is complemented by a heavy soundproofing membrane that reflects the sound wave.

• Air noise insulation index: 33 dB
• Temperature range of use: from -30 to +80, °C
