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

PVC Sound Barrier with Closed-Cell Foam PVC Decoupler

Quick, Clean, and Effective Noise Control for Drain and Waste Pipes

Our PVC Decoupler pipe soundproofing wrap with closed-cell PVC foam backer is a high-performance, roll-applied acoustic solution designed for anyone—from contractors to DIYers—looking to reduce plumbing noise before walls or ceilings are enclosed. This heavy, yet flexible noise barrier combines a dense 1 lb/sf mass loaded vinyl with a soft ¼” thick closed-cell foam decoupling layer to dramatically cut down on annoying pipe and drain noise.

Ideal for drain, waste, and vent (DWV) piping, the material wraps easily around PVC or cast iron pipes and is secured using zip ties and locally available plastic-adhesion tape. No special tools or training required.

• Moisture & Mold Resistant: Built to withstand damp, enclosed wall cavities without degradation
• Safe for Buildings: Meets UL 94-HF1 Class C flammability standards for wall and ceiling assemblies
• Durable & Flexible: Heavy enough for performance, flexible enough for tight wraps and elbows
