Product Description
Both VB-3 and VB-4 are designed to yield maximum attenuation over a broad frequency range. Both offer a significantly higher transmission loss than damper alone. The VB-3 with its lead septum is used in areas where highly flexible and moldable barriers are required, like firewalls and transmission tunnels. The VB-4 with its loaded vinyl barrier is better suited for flat, high impact and high traffic areas, like trunks, floorpans and truck beds. Cabin flooring for both RV and marine are also excellent application areas. VB-3/VB-4 thickness: .250". Not adhesive backed.
