db Shield is a lightweight, thin, and highly moldable vibration damping material consisting of vinyl-based sheets.
Designed to mold and conform to irregular surfaces, db Shield achieves a 100 percent bond, maximizing damping performance.
Stretching up to 40 percent, db Shield makes an irregular surface appear as if it has been dipped in plastic.
It has less than half the weight and twice the damping of asphalt damping materials, handling continuous temperatures up to 250 Degree F.
Consisting of a proprietary component blend in a lightweight vinyl carrier, db Shield has been engineered to convert structural resonance (vibration) into low-level heat through friction.
The friction is created from the proprietary component blend coming into contact with each other as the substrate (or panel) vibrates.
Ideally suited to create or replace a vapor barrier behind an interior door panel, db Shield is much more dense and rugged than flimsy plastic provided by many OEM's.
This makes db Shield far more capable of blocking airborne sound that normally enters the vehicle via the doors.
Additionally, db Shield blocks speaker back-wave and prevents an acoustical short circuit, improving audio system performance by preventing the conversion of sound energy into vibration energy, giving your speakers cleaner, crisper sound.
