Trademark Soundproofing Mass Loaded Vinyl 1lb - MLV Soundproofing for Wall Sound Barrier - Sound Insulation - Made in USA - 4' x 4' - 16 Sf

I recently use 1 pound mass loaded vinyl for soundproofing my living room and it is fantastic. It’s significantly cut down noise and it was easy to cut and fit, but we had a hard time putting it up because of the weight. We installed it along with wood panels since my TV wall in the living room is against my bedroom wall, and it made a huge difference in reducing the noise. The quality is excellent, and it feels durable and long lasting. While it might be a bit pricey, the noise reduction benefits, made it worth it. I highly recommended for anyone needing to reduce the noise

I purchased 6 panel solid wood door slabs to reduce noise through our interior doors (we had hollow core doors before). I wanted more noise reduction so I bought some of this MLV. I attached it to the inside of my interior doors with Liquid Nails Fuze It caulk and used an 18 gauge stapler to secure it to the door. Excess is easy to trim off with a utility knife. I then stapled 1/4" thick natural wood panels on top of the MLV and am going to paint them white. I am VERY happy with the amount of increased noise reduction that this MLV provided. My wife also thinks it was well worth the price. I also used white rubber weather stripping to help seal the gaps between the door and the frame when the door is close. This combo reduced the noise coming through the door by at least 90%. 1lb MLV will increase your door weight by 1 pound per square foot of door, so it added around 20 pounds to the weight of each door

4 stars instead of 5 because I wish it were cheaper! First, the odor - the roll I received had little or no headache-inducing vinyl odor. Double thumbs up. Second, the application. My particular situation - I have a drum kit set up in my basement. The concrete foundation is good at blocking noise, but the windows at the top of the foundation, not so much. I don't want to bother the next door neighbors with loud drumming. The solution to this particular problem is to get 3" mineral wool, cut to fit the window opening, then cut a same-size piece of the MLV material and put on top of the mineral wool. The stackup of materials, from the outside in, is glass + mineral wool + MLV. This doesn't block 100% of the sound, but it does a really good job. In this case the MLV is one part of the solution. I put the mineral wool/MLV combo in a heavy duty plastic garbage bag to prevent dust coming off of the mineral wool into the basement space. There is nothing magical about the MLV - it is just a mass layer. Other materials of similar density and rigidity (rubber mat for example) would also work. The MLV advantage is it is very flexible and cuts easily with a razor knife. And you can fasten it or glue it fairly easily to another surface.If you are trying to block sound from an adjoining room or apartment, however, this can get really tricky because the sound can travel through many paths. Even if you completely cover one wall with a sheet of MLV (or an insulation layer such as the mineral wool plus the MLV), this may not effectively block the sound if the sound is also traveling through another path to get into the space you are trying to make quiet. Sort of like the water dripping through your ceiling, sound will go wherever physics permits it to go. There is some reasonably good practical information at this website: soundproofcow.com. This is a commercial website, and I am not endorsing their products, but you can find some good info on approaches to noise control here.If you want to study the physics of it all, get the book "Noise and Vibration Control", edited by Leo Beranek.

it is effective!

Very thick and heavy plastic material. Thank goodness I was able to cut with plain shears. It was a little hard for me putting it up because of the weight, but I attached it to the door with nails, and it worked. I also put a little around the door to the wall and made sure to cover the space at the bottom of the door. I tested it out with a loud TV, and it gave above 90% noise cancellation, and that is better than I can ask for. I would use it again by borrowing a man's muscles to help out. Very good product. It works way better than those felt squares and the so-say noise cancellation foam squares.

I live in a townhome and there is a portion of my master bathroom that has no sound proofing in the common wall. I can literally have a conversation with my neighbor through the wall. My plan was to apply this on top of the drywall since I can’t open up the wall because it’s shared. I applied it on top and can still hear everything at the same volume and pitch. I wanted to apply shiplap over it to hide the vinyl and also possibly get some more sound reduction. However, since it didn’t reduce the noise at all, there’s no point of doing it anymore. The package was heavy, but installing it wasn’t too difficult. I just nailed it into the drywall and the studs and it held well.

I used this in conjunction with some sound Rockwool insulation. It cuts easy and did not smell. If you buy a big roll it is heavy you definitely need help Don't be a hero trying to pick it up by yourself. I did purchase mass loaded vinyl tape and tacks also. No problems with delivery The big roll came by Amazon box truck.

This MLV made up a large part of the cost of my attempted sound proofing project. I'm really not sure it made much difference. I covered mulple finished walls with it, and added a 5/8" layer of drywall on top, and it is only marginally better. I guess I wasn't expecting a miracle, but I was hoping for better soundproofing than I got. Not a good value for the money.
