Acoustical Properties

Airborne sound transmission class/STC 27 per ASTM C423.

Mass Loaded Vinyl External Pipe Lagging – Sound Transmission Loss (STC)
125 250 400 500 1K 2K 4K 5K STC
Mass Loaded Vinyl Pipe Lagging 13 17 19 21 28 33 40 42 27

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.

pipe2Pipe 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.
