Mass Loaded Vinyl Pipe Lagging with Decoupler

  • Reduces Sound Transmission
  • Contains Intrusive Noise
  • Improves Health and Safety
  • Provides Thermal Insulation

 

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 a heavy vinyl barrier with a foam backing called “noise barrier with decoupler”.

Acoustical Properties

Airborne sound transmission class/STC 27 per ASTM C423.

Mass Loaded Vinyl Pipe Lagging w/Decoupler – Sound Transmission Loss (STC)
125 250 400 500 1K 2K 4K 5K 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 material applied to piping or other structures will vary in performance.

pipe2Acoustical Pipe 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 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.
