Custom Acoustical Barriers

Polyfill products are based on mineral filled, ethylene co-polymer formulas that impede the transmission of sound waves, thereby reducing noise within a given environment. This acoustical barrier effectively reduces noise on its own, but takes on enhanced acoustical properties when combined with sound absorbing materials. The flexible and customizable nature of our acoustical barrier allows us to provide customer specific solutions to various industries.
