Soundac PVP is a metal sheet with sandwich anti-drumming designed to reduce vibrations and noise transmission. Soundac PVP consists of two metal sheets with a thin viscoelastic inner layer.
Soundac PVP provides a significant improvement in comparison to a normal metal sheet. The high loss factors make is very well suited for e.g. ceilings, walls and even floor systems.
The system is based on the principal of sandwich anti-drumming with a constrained layer. When the Soundac PVP sheet starts to vibrate the vibrations are converted to a small amount of heat.
