Comparisons are often made between mass loaded vinyl (MLV) acoustic barriers and Peacemaker acoustic barriers.  In discussing the similarities and differences between Peacemaker and MLV, it’s important to emphasize the importance of balancing quality and affordability when shopping for acoustic barriers.

Overall, Peacemaker acoustic barriers offer superior value to customers.  Also, unlike vinyl acoustic barriers, Peacemaker is made from natural and recycled materials, making it an environmentally friendly choice.  Peacemaker acoustic barriers are moisture and mold resistant and dense enough to lay or hang flat between walls, floors or ceilings.  

So why choose Peacemaker acoustic barriers over MLV?

  • Price - MLV indeed may be more effective but it’s also extremely expensive, making it overkill for most projects
  • Ease of Installation - lighter, more flexible product makes Peacemaker easy to install and less expensive to ship
  • Green Product - Peacemaker is made from recycled tires, making it an eco-friendly choice for your immediate environment and the greater one as well

Customer Reviews


I used Peacemaker for a noise problem in my apartment located in a (very busy) town center.Incredible about of noise from heavy machinery from nearby condo towers construction, noisy neighbors, at all hours was making my bedroom impossible to sleep in. I took the measurement of the two tall bedroom windows where the source of the problem came from. I decided I would cut two "sheets" from the Peacemaker roll, one that would fit in inside frame of the window, against the glass, and the second one to cover the window casing, flush to the wall. I was happily surprised when I hung the two Peacemaker squares as just described, because it really did create a peace! I was able to sleep again without being jarred awake as the material was able to keep out the noise. I have been delighted by how well it has worked and is working. However, I did have some trouble after first figuring out how to get them to hang vertically from the wall (top of the window frame). I first tried a few different nails, including finishing nails, but the weight of the piece caused it to tear from the nail. My second approach worked: I went and bought some Velcro (1" wide heavy-duty kind) and this did work and was how I was able to hang the heavy Peacemaker pieces I had cut. The only con I've experienced is the annoying rubber smell. However, this has been diminishing as I've ventilated the room by opening the window and propping up the peacemaker "sheet" to let in a bit of air. Perhaps Audiomute can find a way to develop or obtain Peacemaker material so that is does not give off any odors or have the material breathe without losing it's noise eliminating qualities.

After moving into the apartment directly above my boyfriend, I soon discovered I could hear every little sound from the bedroom directly below mine. I work swing shift and often need to be up at 3:30 am. With teens in the bedroom below me the sound issue was destroying my relationship with them and their father. The first soundproofing product I found was Peacemaker and the name really caught my eye. I looked further but didn't find anything else that would have worked. I placed my order on Sunday night and received delivery on Tuesday afternoon. Working from the bedroom downstairs, we removed the tiles from the drop ceiling and revealed 3-4 inch gaps between the walls and the original ceiling. I cut the Peacemaker sheets into manageable lengths to fit around hooks and wires and cut the corners so I could staple the sheets to the wall in order to cover the gaps. I was easily able to cut the rubber with a razor knife and scissors. After covering the gaps, I then stuffed insulation between the ceiling and the ceiling tiles. Although I can still hear muffled giggling, I no longer hear complete conversations. I completed the project last week. So far I've been able to sleep in quiet and can feel the tension easing in my relationship, as well. --Daria Ferrantino

Your product is all you say it is, I used your 3.2mm Peacemaker on a party wall, affixed to wood lath over old dry wall, then installed new drywall after extending wall outlets on wall.The STC is GREAT !!! no more neighbors noise, we get total peace and quiet. This is my second time at Audimute, This is a good company,with a great product, and good people... Your people are AAA+ all the way. Thank You Audimute.!! M Paul Sparapani, Margate Fl.

I am very satisfied with my Audimute experience . I love the ease at which it was to shop, get information, shipping, and when I opened the boxes there was not a single problem to be found. The products themselves were constructed very well and work amazingly. Thank you to all and keep up the great work. I will be shopping with you again in the future. I have also been recommending your company to every person I know who needs these materials.

I'm very satisfied with Peacemaker. My original product choice was on backorder for almost 2 weeks. I had made the decision to cancel, since I was holding up my contractors. Mallory was very helpful and upgraded me to a similar product that shipped that very day. I was grateful, and everything arrived 2 days later. Thank you!

I own a 99 F350 Ford that we pull a fifth wheel with, the noise in the cab is quit loud. I used your product to put under the carpet and behind the rear seat, I would say it cut the noise by at least 50% and has made it a nice ride know. Thank you for a good product. Michael

Audimute products are easy and simple and they get the job done right!! As soon as Peacemaker 3.2 and Sound Absorption Sheets were installed, you could hear and feel the difference in the vocal booth. I was amazed how effective these products are.

Fire Safety

Peacemaker has been tested in accordance with Consumer Products Safety Commission FF 1-70 Pill Test as a standard to determine the surface burning of materials when exposed to small scale burning source. Peacemaker has passed the test, self-extinguished with no measurable flame spread.  For floor applications, thermal barrier and structural requirements are met by using either a raft thickness of 5/8" or more of plywood or 1 ½" of gypsum concrete.  Always check with local building codes regarding installation of all building components. ended materials for soundproofing a floor.

Consider Peacemaker noise barriers for your next DIY soundproofing project. Peacemaker products are eco-friendly and cost-effective flexible rubber noise barriers available in various thicknesses. Ideal for DIY soundproofing, apartment soundproofing, commercial installations, studio and home theatre soundproofing and much more.

Please note: You cannot add STC ratings together to obtain estimated STC ratings in a partition/wall configuration.  For example, the addition of Peacemaker sound insulation (2 mm.) will increase the STC of a wall by estimated 2-3 points, whereas the addition of Peacemaker (3.2 mm) will increase the STC rating by estimated 4-5 points. Adding double layers of each material further reduces the transmission of sound, by as much as an  estimated 10 points when using the 3.2 mm insulation.  STC does NOT provide enough information about a material’s isolation properties.
