Acoustical Transmission Loss properties are for a single layer of barrier material. Actual STC of pipe wrap insulation applied to piping or other structures will vary in performance.

Pipe wrap insulation dramatically reduces the amount of noise that transmits through the walls of ductwork, PVC and cast iron pipes. When a decoupler layer is added sound transmission is improved.

CAUTION: Polyurethane foam is flammable and may emit toxic fumes when burned. Do not use near open flame. Check local codes for allowed use. Manufacturer assumes no liability.
