Quieting Noisy Waste Lines
I want to finish part of my basement, but my main waste line runs along one of the walls and it’s very noisy when water goes gurgling through the pipe. How can I reduce the noise?
Noisy waste lines are a more common problem now that most main waste lines are plastic (PVC) rather than cast iron. The fastest and most reliable (but not necessarily the least expensive) solution is to install an acoustic pipe wrap insulation with a foam backing called “noise barrier with decoupler”.
Mass Loaded Vinyl and PVC Foam with Decoupler
High density limp material with acoustic foam decoupler to reduce noise transmission.
Reduces noise transmission through ceilings, walls, floors, machinery, & equipment, enclosures, PVC waste pipe, HVAC ducts. Apply on any solid surface or on floor under carpet for effective noise containment.
54″ Wide × 20′ Roll; custom sizes available.
UL 94-HFTI Class C (Class A available upon request)
Metal collars or bands. Pipes can be wrapped and taped in place.
Airborne sound transmission class/STC 27 per ASTM C423.
|Mass Loaded Vinyl Pipe Lagging w/Decoupler – Sound Transmission Loss (STC)|
|Pipe Lagging w/Decoupler||13||17||19||21||28||33||40||42||27|
Acoustical Transmission Loss properties are for a single layer of barrier material. Actual STC of acoustic pipe wrap insulation applied to piping or other structures will vary in performance.
Vinyl pipe wrap lagging dramatically reduces the amount of noise that transmits through the walls of ductwork, PVC and cast iron pipes. When a decoupler layer is added to the acoustic pipe wrap insulation, 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.
