1 lb Mass Loaded Vinyl MLV Soundproofing Barrier, See Options

Used as a sound deadener over an existing ceiling along with another layer 5/8 drywall. Doesn’t do great blocking all the impact noise, like footsteps on hardwood and doors closing, but definitely muffled neighbors' voices and music to a noticeable degree, except heavy bass tones. It worked as intended and I’m happy with results. Though it was a lot of work, stuff is heavy! It is expensive so you will have to decide if potential peace and quiet is worth it to you?

I had never worked with this type product before and after using 9 rolls, it's exactly what I needed. Although it's heavy, that's what I needed. I used this as one (1) of a four (4) layer subfloor in an older condominium (a soft layer, Soundsulate, 1/4" plyboard, engineered vinyl . The sound dampening was super helpful. The distributor was nice enough to refer me to the manufacturer for their feedback. I received a call back right away and the gentleman was very helpful as far as being a soundboard for usages and application. What they recommended is to not just take up the subfloor but to remove the baseboards as well and push the product under the drywall all the way to the 2x4 that is bracing the wall otherwise there is a gap that allows sound to go up into the walls and you're not getting the proper usage of the product. I also used a soundproofing calking around the edge next to the wall brace. Being new to this type of DIY job, I could not have had a better experience. With the lessons learned I would certainly use this product again but I would also consider a heavier pad. This does not stop structural noise, that requires going into the walls.... different project.

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.

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.

This product smells absolutely disgusting, even after letting it air out for 2 days and washing multiple times. It makes me sick. It was described as having no smell. Their support doesn't even exist and it redirects to some AI website that hasn't been established yet. Such an awful waste of money I really have no clue how it has positive reviews.

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.

As much continuous coverage as possible is the key to success. My extremely noisy Prius C now has a quiet interior. I can now use the handsfree telephone features at highway speeds without cranking up the stereo volume to painfully loud levels while still straining to hear. Dismantling the interior of the car then covering every square centimeter with this material is a time consuming project and it is so worth the trouble. I feel like I drive a luxury vehicle now. I used this in conjunction with an 80 mil thick vibration dampening butyl rubber applied to the inside of the car’s metal body. Then the MLV goes over that. 10/10 would do again.

I will put the caveat on here that this review is for sound dampening a pickup truck, which is not the original intent of the product. The product could work well in a household application, but I know it did not have much of an effect for my automotive experience. I recently installed this 1lb mass loaded vinyl product on the floor and doors of my Dodge RAM 2500 2004 quad cab pickup truck to enhance sound dampening while driving down the highway. Unfortunately, even when combined with 80 mil noico butyl CLD, I did not achieve results any better than the stock carpet and asphalt dampeners. I removed the old, hardened, stock damping asphalt CLD and replaced it with "superior" butyl. I made sure to cover as much of the floor as possible while making minimal cuts in the MLV, as you can see in the pictures. I also replaced the old carpet with a vinyl floor for easier cleaning. Unfortunately I did not notice any change in the sound levels. I used Decibel X to measure sound damping before and after. I made sure to take the pickup out on a calm day both before and after measurements. Before installation: 54 dB @ idle 60 dB @ 30 mph 64 dB at 60 mph 66 dB @ 70 mph 65 dB @ 40 mph on a dirt road After installation, with 1lb mass loaded vinyl: 56 dB @ idle 59 dB @ 30 mph 65 dB @ 60 mph 66 dB @ 70 mph 67 dB @ 40 mph on dirt road I have to admit, the sound dampening effect was below my expectations. I suppose if you are working on a vehicle without any dampening at all, you would notice a big change. I will say 100 sq ft of 1 lb / sq ft mass loaded vinyl was more than enough for 100% coverage. 36 sq ft of CLD was more than enough to cover about 1/3rd of the metal surfaces underneath the MLV. Another thing to note, if you're considering such an upgrade yourself, I would highly recommend not trying to install your own vinyl flooring. The wrinkles in my vinyl flooring haven't come out and it's been almost a week. The stuff is hard to work with and I screwed up more than once. Overall this project didn't come out like I had hoped.
