AudioSeal® Sound Barrier is a mass loaded vinyl (mlv) sound barrier used to reduce the amount of airborne sound from transmitting through walls, floors and ceilings. It can be added to various construction assemblies to increase STC (Sound Transmission Loss) of the structure. It is a limp-mass material made of high-temperature fused vinyl and no lead fillers. Audioseal® Sound Barrier is very dense, weighing one to two pounds per square foot. AudioSeal® is commonly used in new construction and also to correct noise problems in existing spaces.

Audioseal® Sound Barrier is a non-reinforced version for wall and ceiling installations. AudioSeal® is tear resistant, yet easy to cut with a utility knife. Its available in 48″ or 54″ widths and various lengths to provide the best utilization for your project.

Usually installed direct to the studs, vinyl sound barrier may also be installed between layers of drywall. Often, the mass loaded barrier is used in combination with other materials to create a soundproof system. Combining it with layers of sheet rock with Green Glue and resilient clips and channels will improve the sound transmission loss of the complete assembly. Reading about Soundproofing a Wall and Soundproofing a Garage may provide you with further insight on the uses of mass loaded vinyl in certain construction assemblies.

  1. Brian Davis

    All I can say is, it is heavy. I'm an amateur, first time working with this. Building a personal drum / recording studio. Learning as I go. The product is what it says. Hoping it works as I intended.

  2. Angela Stanley

    Product was delivered timely and as described. We installed on wooden fence to flatten dog barking. I have not heard from my neighbors so hopefully it has helped.

  3. Anthony Repass

    great product for soundproofing

  4. Philip H

    High material. Arrived in excellent condition.

  5. Judith

    Great product that works! Easy to install. A 8ft high x 12 ft wide wall took only two men and less than a day to hang and cover with drywall. Now the noise of a 4 lane highway only 30 ft from the house is minimized to the point of not even noticing any vehicular sounds.

  6. mdAudio

    excellent … liked the size option

  7. D. Davis

    Great stuff!!!

  8. S.S Karawi

    this stuff is heavy. takes a little man handling to get it in place. We used it on the ceiling in the theater to help deaden the sound transmission to the HVAC ducts and bedrooms above.
    this is part of system, so still in the building phase of the theater, hard to tell if this helps at this stage, but figured better safe than sorry. it is relatively inexpensive to include during building, but would be very costly to try to add after the fact. so I consider this cheap insurance.

  9. Chris Sears

    Works ok for underpayment material for carpeting when not doing new construction.

  10. Plasterform Inc

    We are using this product as a substitute for another acoustical treatment. Seems to work well for our application.

  11. carl

    great product!

  12. Custom Building

    Didn't do the job that was promised

  13. Hathaway Dinwiddie Construction

    Does what is advertised.

  14. Gregs Construction LLC


  15. Matchless Construction Group I

    Did what it was supposed to. We fit it into inset panel doors to reduce sound transmission from room to room. Good results.

  16. Verified Customer


  17. Verified Customer

    Used to insulate the space where my air handler is. It is much quieter since I have installed the sound barrier.

  18. Verified Customer

    Excellent material to sound proof a house or a cinema room

  19. Verified Customer


  20. Verified Customer

    We purchased this product for soundproofing office walls. (was specified by an architect)

  21. Verified Customer

    Worked well in ceiling application.

  22. Verified Customer

    The only reason I gave four stars is the material is hard to work with. No fault to the design, it's just so heavy and flexible, getting it on a wall and especially the ceiling is very hard.

  23. Verified Customer

    Arrived as expected and in perfect shape. Product is as described.

  24. Verified Customer

    Used for soundproofing studio. Works wonderfully.

  25. Verified Customer


  26. Verified Customer

    very good sound barrier.

  27. Verified Customer

    Does a great job!

  28. Verified Customer

    Weighted vinyl is very impressive. Yes it is heavy but what would someone expect from a sound proofing tool/product. Easy to work with and very strong. I’m installing it in the walls and ceiling of my studio. Highly recommended. When properly applied, this is top notch, very professional sound controlling product.

  29. Verified Customer

    To soundproof my basement

  30. Verified Customer

    Music room sound proofing.

  31. Verified Customer

    We use this inside trucks to keep outside noses out. Recommend this to anyone that needs to keep noise out and the quiet in.

  32. Verified Customer

    I have a 5×8 Mobil grooming trailer with a generator. We covered the inside walls and ceiling then useded pink foam insulation from Home Depot to fill in space from vibrations.

  33. Verified Customer

    We are using the mass loaded vinyl on our wood fence to block road noise. Works really well.

  34. Verified Customer

    Perfect sound decoupler for my car.

  35. Verified Customer

    I use it as sound barrier against loud neighbors. It makes a big difference, but of course, some noise still spills over the fence.

  36. Verified Customer

    How many effective and simple to use

  37. Verified Customer

    Surprised by the thickness

  38. Verified Customer

    Audio Seal Sound Barrier is serious sound blocking material. Loosely hung, I can't imagine a home theater without it. It drastically cuts sound transfer (and Acoustical Solutions had the best price for a mass loaded vinyl product!)

  39. Cindy Lewis

    More comments from satisfied customers. The sound barrier was installed yesterday and I put my boom box in the room, cranked it up, ran upstairs and could not hear a thing!!! Awesome. The sheet rock went up last night on the ceiling and I found that my singing sounds quite nice in the room! Maybe I should turn it into a recording studio. Thanks for your help.
