Product overview
The VBB EV 7.0 is our premier noise barrier for the most critical areas of the vehicle, such as the floor and wheel arches. It features a sophisticated “sandwich” construction that combines a 3mm heavy acoustic membrane with a 4mm layer of lightweight Aerospace Mastic . This design leverages the “Mass Law” principle with a density ratio of approximately 2.5:1, effectively blocking low-frequency road noise and rumble. It offers a sound insulation improvement 28% higher than previous generations while maintaining a lighter weight profile suitable for electric vehicles.
Key product details
- Advanced Sandwich Design: Combines a heavy blocking membrane with a vibration-absorbing ASRM base for dual-action noise control.
- Superior Isolation: Delivers significantly higher sound insulation (ΔR) compared to standard multilayer mats, working effectively from 150 Hz to 10,000 Hz.
- Thermal Stability: The ASRM layer provides excellent thermal insulation, helping to regulate cabin temperature and reduce energy consumption.
- Aerospace Technology: Replaces traditional foam layers with our aero-granule mastic for better durability and performance without bitumen odors.
