Pipe Noise S.T.O.P.™: Vinyl Pipe Soundproofing Wrap


Mass Loaded Vinyl Pipe Wrap 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 an acoustic pipe wrap insulation with a foam backing called “noise barrier with decoupler”.

How to DIY Install Mass Loaded Vinyl Pipe Wrap

  1. Measure and cut: Measure the length of the pipe you want to wrap and cut a piece of soundproofing wrap that is slightly longer than the pipe to ensure full coverage.
  2. Prepare the surface: Clean the surface of the pipe to remove any dirt, dust, or grease that may hinder the adhesive or reduce the effectiveness of the soundproofing wrap.
  3. Apply adhesive (if applicable): If your soundproofing wrap has an adhesive backing, peel off the protective layer and apply the adhesive side of the wrap directly onto the pipe. Make sure to press firmly to ensure good adhesion.
  4. Wrap the pipe: Begin wrapping the soundproofing wrap around the pipe, starting at one end and working your way along the length of the pipe. Apply firm pressure to secure the wrap in place.
  5. Overlap the edges: As you wrap the pipe, overlap the edges to create a tight seal. This helps to prevent sound or vibration from escaping through gaps in the wrap.
  6. Secure the ends: Once you have wrapped the entire length of the pipe, secure the ends of the soundproofing wrap with tape or adhesive to ensure they stay in place.
  7. Repeat if necessary: If additional layers of soundproofing wrap are desired for increased sound treatment, repeat the wrapping process, overlapping the edges of each layer.

Inspect and adjust: After installation, inspect the wrapped pipe to ensure there are no gaps or areas where the wrap has come loose. If necessary, make any adjustments or reapply adhesive to secure the wrap properly.

Acoustical Properties

Airborne sound transmission class/STC 27 per ASTM C423.

Mass Loaded Vinyl Pipe Lagging w/Decoupler – Sound Transmission Loss (STC)
Pipe Lagging w/Decoupler131719212833404227

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.

pipe2Vinyl 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.
