Noico 80 mil (2 mm) 36 sqft (3.4 sqm) car Sound deadening mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

I had some custom door panels built for my car, and while they were being worked on realized the factory vapor barrier was in very poor shape. After some looking around, I decided to give this stuff a go - it gets favorable reviews from professionals against much more expensive products - like "90% as good as Dynamat for 50% of the price." Since I don't care so much about noise and was mostly trying to address missing vapor barrier, it seemed like a good fit for me.As I'd been driving around for a couple months with no trim on the doors, I really can't comment on how well this stuff does at sound deadening. The interior feels quieter than I remember, and the doors closing seems even more solid than it did before. But it's just how I feel, I don't really know.What I can comment on is that's very easy to work with. The diamond pattern gives you slack to deal with non-flat surfaces pretty easily, and helps you know when it's been properly rolled down. The foil layer is ultimately pretty thin, and I had no problem cutting with a sharp utility knife. The only installation issue I ran into is that in tight corners the rollers had a tendency to slice or mangle the foil, but after doing that twice I change my approach and had no further issues. I found with a light touch the mat could be placed and then removed, but once it's pressed down - even by hand - it's not readily coming off. I left my doors open with the mat applied for 5 or 6 hours to be sure it wasn't going to fall down, and it was very clear it was staying put. The 80 mil thickness seems like a good place to be - thick enough there is some mass there, but not too thick it'll interfere with trim going back on. Good choice there. Next day I can detect a *slight* smell from the rubber if I really try, but nothing I would describe as I problem and I am VERY committed to neutral smelling cars.I will log some miles with just the two doors done, but with quite a bit left over I will probably throw some in the rear quarter panels and the roof as well, then maybe I will have a sense of how it performs as a sound deadener. I've worked really hard to shed weight on this car so I'm hesitant to grow back even a few pounds in sound deadener.... but it's for science, right?UPDATE: Following good results with the doors, and having a substantial amount left over, I decided to apply this stuff to the doghouse cover of my older motorhome. The cover is just fiberglass and carpet, so there is a ton of engine noise and heat that makes it into the passenger compartment. I used a fair amount of the Noico, and sealed joints & unions with their "special" tape to ensure the rubber didn't get squeezed out or ooze onto the engine.2000 miles later - including several passes over the Cascades - I can say that this stuff has dramatically cut down on noise, but also improved the heat situation. It's now possible to have a conversation at a reasonable volume while cruising down the freeway. These mountain passes are about worst case scenario for engine heat, and the Noico stayed put and there's no indication of problems - the picture is *post* drive. This isn't exactly analogous to a car since there's a 1' air gap between engine and cover and substantial air flow, it's still putting up with some pretty direct heat here. Cool!

Much cheaper than the name brand stuff I've seen and heard about for years. Just used it to sound dampen my 2006 Infiniti M45 and even though I didn't cover the trunk with multiple layers (used the 25% method) the sound deadening it did was absolutely amazing! I'd recommend this to anybody trying to improve sound quality in their vehicle. My car had so many rattles & shakes that I wasn't sure if I'd find them all, but this stuff really did the trick!!!It doesn't smell bad either (I've read that other brands have a slightly bad odor). This material was easy to cut, adhered very well, was easy to punch holes in also, but you MUST be mindful of that ALUMINUM EDGE because it WILL rip your finger(s) wide open if you're not careful (unfortunately talking from experience).The plastic handle on the Noico roller I got was broken, but it didn't prevent me from using it effectively, and knowing what parts I had already used the roller on. Very helpful & pretty well thought out, but the quality of the roller is questionable.All in all, this is a good buy. In my case, I wasn't able to use all of it on my car because of the method I employed, and the fact that the doors on my car are sealed with a metal cover & rivets, so it's already solid and sealed for the most part. Had I known this ahead of time, I would have only purchased 18sq ft of this material because I have more than half of my box left over.I don't think my sound system would be the same without this stuff!! Wouldn't hesitate to buy it again, although they have a gold model that might be a bit better, but if it is, it must be mighty good!!!Hope this review helped! Best of luck with your intended purpose for this product!

Bought this product to "fix" the hollow, echoey sound my car doors were making.The contents came in a brown box and was much heavier than I originally expected. Roughly 30-pounds.Inside the box were 9 sheets of the sound deadening material, each sheet being 36 square feet.The material was thick, yet easy to cut with a simple box cutter. I was easily able to cut through the material and backing with no trouble what so ever. Applying the deadening mat was even easier. Wipe the exposed metal with alcohol (or alcohol and water mixture), then remove the backing and apply. It's highly advised you purchase a wood roller. I attempted to push it flat and flush by hand. It wasn't long before I noticed LOTS of small but annoying cuts on my fingertips. Use the wood roller if you don't want mutilated fingertips.In short, I spent more time removing and cleaning the door than I did applying the deadening material. For my Subaru Legacy, 1 and a half sheets covered the entire driver side door. That includes the panel behind the door speaker as well as the panel holding the door speaker. I applied the deadening matter pretty thick, there wasn't much exposed metal when I was done. The end result sound of the door went from a very hollow metal sound to a VERY satisfying full door sound. It sounds like the door is one solid piece of metal. In terms of added weight, the door feels no heavier, eventhough it sounds like it weighs a ton when closing the door.The one thing I like is as you're flattening the mat, the black "glue" expands about 1/8-inch beyond the mat, letting you know that it's going to hold firm.In short, I'm very happy with the product. And for those wondering if you have to be a professional to apply this. As long as you can remove your car door interior panel (tutorials are easy to find on YouTube), you should be able to apply this with very little problem and have some good results. Again, PURCHASE A WOODEN ROLLER AND SAVE YOUR FINGERTIPS!Again, great product. As a first time installer of it, the job was easy and gave satisfying results.
