db Defender™ is a thin, lightweight, and highly moldable vibration damping material that consists of vinyl-based sheets. db Defender™ is designed to mold and conform to irregular surfaces to achieve 100% bond, maximizing damping performance. db Shield will stretch up to 40% to make an irregular surface appear as if it has been dipped in plastic. It has twice the damping and less than half the weight of asphalt damping materials and has the ability to handle continuous temperatures up to 250°F.

db Defender™ consists of a proprietary component blend in a lightweight vinyl carrier. It product has been engineered to convert structural resonance (vibration) into low-level heat through friction. The friction is created from the proprietary component blend coming in contact with each other as the substrate (or panel) vibrates.

db Defender™ is ideally suited to create or replace a vapor barrier behind an interior door panel. db Defender™ is much more dense and rugged than flimsy plastic provided by many OEM’s. This makes db Defender far more capable of blocking airborne sound that normally enters the vehicle via the doors. db Defender™ also blocks speaker back-wave and prevents an acoustical short circuit. This improves performance of audio systems by preventing the conversion of sound energy into vibration energy giving your speakers cleaner, crisper sound.

One sheet of db Defender (P/N 040051) is enough to cover one set (2) door panels
