For a Strong, Internal Sound Barrier, Turn to Peacemaker® Sound Insulation


Peacemaker® by Audimute is a heavy rubber sheeting product designed to add mass and density to wall, floor, and ceiling structures as an impact and sound barrier. Crafted from recycled tire rubber, Peacemaker® effectively transforms sound energy into heat and dampens sound transfer between structural elements. Peacemaker® sound barrier offers superior noise reduction and moisture protection perfect with a range of thicknesses designed for walls or how to soundproof a floor. Peacemaker sound barrier is ideal for soundproofing apartments, multi-family residences, condos, commercial spaces, studios, theaters and more. With impressive results at an affordable price, Peacemaker® is the perfect answer for how to soundproof a floor, wall, and ceiling.

2mm Peacemaker® is most commonly recommended for wall applications. This sound room barrier installs directly onto studs or retrofit between sheets of drywall. Audimute’s 2mm Peacemaker® sound barrier has been lab tested for a Sound Transmission Class (STC) rating of 11. This rating determines a materials ability to block or isolate sound. In field testing, 2mm Peacemaker® adds 3 points to a structure’s overall STC score to help reach code compliance regulations for soundproofing in residential and commercial buildings.


2mm Peacemaker® is available in a variety of roll and pallet sizes for every application. Peacemaker® is in stock and available to be shipped directly to building sites for contractor.


2mm Peacemaker® Soundproofing Room Barrier:

  • Made from recycled rubber with superior resilience that will not compress over time, decreasing results.
  • Installs directly to wall studs during original construction or over drywall in retrofit applications
  • STC rated 11 (adding 3 points to finished structure’s score) for sound isolation
  • Natural moisture barrier, reducing potential harm to other structural components.
  • Peacemaker® is also available in 3.2mm and 6.4mm thicknesses for additional wall and soundproof floor underlayment


How to Soundproof a Floor with Peacemaker®

Impact Isolation Class (IIC) ratings are used to determine a soundproof floor underlayment ability to attenuate impact noise. In some field testing, 2mm Peacemaker® has scored a higher IIC rating than our 6.4mm sound battier. However, because of its less-compressed design, 6.4mm Peacemaker® is always the ideal sound barrier when looking how to soundproof a floor.

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

The Peacemaker did a fantastic job with improving the listening environment of my car. The music is much easier to hear, and a good amount of the higher pitched road noise has been eliminated. I'm really enjoying the clarity of the music! I had my brother contact a specialist via chat, and we got all the info we were looking for. The discussion was mainly to verify what we'd already read, and it was simple and clear.

I was looking at the dB-3 sheets, and probably would have gotten that instead, except that Audimute had customer service that I could, you know, talk to. And Audimute was able to ship immediately, which was critical in my case. Arrived 2 days later. Perfect. - Dave

I'm a music producer and a DJ. I was tired of paying out big dollar to go into a studio which people defined as "pro-studios." I purchased a house in October of last year and just got around to building one of the rooms in the basement into a pro-studio. I knocked down walls, built up walls, put up insulation, then peacemaker, 5/8 sheet rock and I was golden baby. No more noise coming into the closet from the utility room at all- it's great! I have nothing but great things to say about this product called peacemaker it works what else do i need to say- it works great.- Hakim Alhaqq

I make instrumentals and record as a hobby and I'm big in quality. Most of recordings are in my basement that is at about 20x20. I would always receive echos and returning sound not to mention my family members upstairs screaming. So I planned to construct a recording booth. I searched soundproof materials. That's when i stumbled on Audimute Peacemaker. It was right for my budget. I ordered 4 and got started with construction on my recording booth. Installation was very easy, and I can already "not" hear results. Pros: The peacemaker is very easy to install. Its cheap and within my budget for soundproofing. The sheets are very flexible. Ive dropped them, stepped on them, nailed and re-nailed over them and they don't tear. Cons: Not much. I'm happy with its performance. -Cheng Kong

Very effective at lowering volume levels from our rocking worship center to children church rooms just one wall away.

I pulled out the entire interior of my Land Cruiser and double layered Peacemaker to the metal floor. It does a great job of reducing the road noise and exhaust noise.

Kudos to Audimute! Happy to purchase your product for my project as well as help the environment. With millions of tires going to the landfills, nice to know you are creating a product to recycle all that rubber.

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.
