Soundsulate 1 lb Mass Loaded Vinyl Soundproofing 4' x 25' (100 sf), Made in USA, Click for Options

Good quality MLV. This alone doesn’t soundproof a room, but it’s great in combination with things like rockwool soundproof insulation, weatherstripping and more. Definitely a staple in soundproofing

I applied this in my 2022 Ram 1500 Limited to isolate inside and outside noise. It was super easy to work with using a box cutter and drill bits depending on the situation. I shopped around and this was where I fell on value for my money compared to other MLV products. It's very workable and was highly effective in reducing road noise when applied to my inner doors, rear wall, and floor pan. I attached it using factory bolt locations. It did not come with any adhesive backing, etc. which I expected. I purchased some 3M spray adhesive, but decided to use factory bolts to hold it in place instead, so it would be easy to remove if I needed to service my inner doors in the future.

My client wanted to enjoy his home theater experience without the entire house hearing it. If I had my way I would have put MLV b4 the drywall. But it did work well on top of the drywall. I was able to reduce the sound outside the room by 60%.I used roofing nails and a staple gun to Secure all the panels. You definitely want to have someone help you because the material has a little weight to it. To close all my seams I used a MLV tape.The other cool thing about the material I used every last piece of it. No need to waste any of it!!

So, mass loaded vinyl is heavy, cumbersome, and delicate. It tears easily, weighs a lot, and is difficult to install.That being said, it's good for reduced the sound in an area that's oddly shaped. This mass loaded vinyl does about the same work of sound resistant sheetrock. However, it's flexible and easy to cut, so it can be installed around utility lines, HVAC, and uneven beams (all of which I did).You will need industrial strength bonding agent, as it's too heavy to adhere with regular adhesives.

We live in a condo with a shared wall. On the other side of the shared wall are newborn twins. We love children, but during the night the crying was more than we can handle. Even worse, our bed is next to the wall. My wife and I were skeptical at first but decided to give MLV a try based on our research and positive reviews. The MLV arrived as expected. We nailed the MLV to the studs behind the existing drywall: caution – it is heavy! We used the recommended acoustic sealant around the perimeter being careful to cover all the gaps and outlets. We then covered the MLV with more drywall, again making sure everything was sealed. We learned from the installation instructions that sealing is key. We taped the drywall seams and painted. Today, you wouldn’t know that there was anyone living next door. Amazing stuff. We will be buying more.

I used this to dampen sound from a neighbor who has her kitchen and living room on the other side. She uses a machine, vaccum, and drops heavy furniture on the floor. After covering the entire wall, floor to ceiling with the 1 pound MLV, there was no noticeable difference. I could still hear her talking in a normal voice as well as all the other louder noises.

This is NOT odor free. It's off-gassing a lot. I unrolled and aired it out in my shop for a day, whole shop smelled like chemicals. Let it air out in the sun another day. After spending 5 hours installing in my truck, have a bad headache. But it's a lot cheaper than any of the professional sound deadener company MLV. When combined with CLD tiles and closed cell foam, it does really help cut the noise. I'm just hoping the odor abates quickly.

I’ve purchased several rolls of this 1lb mass loaded vinyl sheet from this supplier, and it has consistently delivered on quality, density, and material expectations—no surprises whatsoever.As is natural with this type of material, there is a slight smell when first unboxed, but letting it sit in the garage for a few days resolves that completely. Compared to other options on Amazon, this product has stood out for its reliability and performance.Whether for soundproofing or other applications, this product has not let me down. I’ll continue to purchase from this supplier for any future projects. Highly recommend!
