VEVOR Car Sound Deadening Mat, 200 mil 25 sqft Butyl Sound Deadener, Noise Insulation and Vibration Dampening Material

What I really like about this product is that it's very budget friendly and can be had for cheap when Vevor is running coupons or discounts here on Amazon. I've installed Dynamat and Noico in the past in multiple vehicles. What is great about this product is that is has the normal butyl mass layers that lowers the resonant frequency of your car's light panels but that it ALSO has a thin foam decoupler layer on top. This layer stops plastic doors panels and wires connectors from making noise when they rub against the panel. The adhesive strength and cutability is similar to other products that I've worked with in the past. I'd buy this again in a heart beat.

So I purchased this stuff for my DIY CNC enclosure, I ended up measuring the sound after the install with the door open and closed.Door open = 80.2dbDoor closed = 46.5 dbThat's a 42% reduction in sound from just a few of these on select surfaces and features of the interior of the enclosure. And a 38% reduction from just insulation foam and wood.I'm pretty sure if I add more I can get it to 50% reduction in sound.I'll be using this stuff in the future as a liner for my big 3D printer enclosure.It really knocks out the high pitch sounds, the low stuff kicks through it though. If you layer it I'm sure it's better.I purchased the thick stuff, but I wish that had something thicker than 200mill. This will stop almost all high pitch sound though and that is what I really needed for my project.Also the adhesive backing sticks to almost everything, wood and foam insulation sticks fine to it. Don't let it get on carpet though 🤣Will be keeping this is my arsenal of building materials.

I think I paid $18 per 25sqft and I got the best deal I could have imagined. Make sure to clean the surface with a degreaser and then with soapy water. Works great, easy to work with, finished result is perfectly adequate. The only downside is it is easy enough to rip the top foam layer, but that’s easily resolved by not sliding around on it while installing. Lift your knees and feet and you’re good to go. Definitely has a stink for a bit, but that’s good. It is butyl after all. If it didn’t smell I’d be worried haha. 200mil thickness is about 2mm or so but with MLV on top, any thicker and you’d have an almost impossible time reinstalling interior. I can’t really tell if it’s made a difference in heat or temperature.

I actually used 1 of the sheets to line the inside of a Eureka Filtro coffee grinder case.The body of the coffee grinder is aluminum and produced a higher pitched sound while grinding the beans. With the Vevor mat installed on the inside of the case, the sound was lower pitched and softer.

I bought 3 brands of butyl sound deadener to see which one lived up to the hype and the best value. Measured a random sheet out of each box with calipers in 20-30 spots around the sheet, then weighed on a digital scale.- Vevor 80 mil butyl is 80 mil thick average. Sheet weighs 10.87oz and is 145sqin (10"x14.5"), which calculates to 13.4sqin per ounce. This was the heaviest butyl of the bunch, nice and sticky, no noticed odor. Installing this sound deadener.- Kilmat 80mil butyl is 80 mil thick average. Sheet weighs 8.2oz and is 160sqin (10"x16"), which calculates to 19.5sqin per ounce. Sticky, but weighs the least and I could notice an odor while handling it. Sending back.- Uxcell 80 mil butyl is actually 65 mil thick average. Sheet weighs 9.67oz and is 151sqin (9.75"x15.5"), which calculates to 15.6sqin per ounce. This was the least sticky of the bunch, probably poor adhesion as mentioned in another review, no noticed odor. Sending back. (65 mil = false advertising?)As for sound deadening qualities I'm not sure how Vevor will compare to Kilmat, but Vevor is heavier and it's less expensive.

This stuff is great. A little thicker than I would have thought but that’s a plus. I used this on my Tacomas plastic door panel because it had some rattles and decided to put some on the door itself as well. And boy I tell you what, the rattles are gone! I can now play bass heavy music without being annoyed of any rattles. 10/10 recommend

Why spend a fortune for this type product. Easy to install. Easy to size to fit. Adhesive backing is strong. You must, however, use a quality roller or your results will be poor.

great product for not alot of money
