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

Works great. Used this in my jeep. Put inside door panels and on celing. Noise is reduced. Very easy to work with and easy to cut. I would strongly suggest using disposable gloves when applying this. It is very sticky and the skin on your fingers will take a beating if you don't use gloves.

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!

Just finished installing this in the main cabin of my '98 Jeep TJ. I pulled the OEM carpet out, center console, and the rear and passenger seats, then performed a sound test using a db measuring app on my iphone 6s at 65 mph with the app running and measuring and held at head-height over the center tunnel. Outdoor temp was 91 F with high humidity at 3pm. Had soft top on with all windows on and closed as well as full steel doors with windows up. Had blower on 3rd highest setting to keep the soft top from flapping and slapping. Measured for one mile on level road. App measured a consistent 92db. Using one box of 80 mil, covered entire floor area and sides, excepting the tailgate. Measured db levels again-outdoor temp was 87 F with high humidity at 3 pm on the same level stretch of highway at the same speed with soft top on, all windows in, full steel doors with windows up and blower set on 3rd highest setting to keep the top from flapping and slapping. Measured for one mile, and app measured a consistent 71db. Returned home and installed new carpet with mass backing, center console, front and rear passenger seats, and measured again on the same stretch of road and same conditions of soft top and doors with blower on 3rd highest setting. App measured a consistent 64db. Interior is noticeably cooler as well, and the majority of noise is coming from the bare tailgate and the soft top. At 55 mph the sound level drops to 61db. Note that I did not install on the tailgate, inside the doors nor on the inside rear wheel wells. Given these results I feel that this product is well worth the price and the work to install. Definitely have leather gloves, a sharp knife, a silver and a black sharpie, some cardboard as a cutting surface, a roller, and a high powered hair dryer for heat-blow torches and heat guns are not necessary. When cutting and trimming, cut slightly larger than your pattern. For larger size install pieces, I recommend grabbing a helper at the least. If a helper is not available, then only peel 1/3 of the backing paper off from the area that's farthest from you and install that first. Once that is in, carefully peel off the remainder and slowly apply the rest. Start from the center of the sound deadener and smooth outward from there to remove air pockets. Roll with the roller until you have flattened or mostly flattened the little triangles in the foil. Save all of your offcuts so that you can fill in the irregular shaped areas later. Start with the largest areas and cover those first. Keep a small bag or box handy to put all of the little pieces you trim off-this will keep these from becoming a mess later. Take your time and budget twice as long as you think you will need. Hope this is helpful.

Great value. I bought this as an more cost-effective alternative Dynamat. Came quickly, went on as described. I did front and rear doors of my 2017 Toyota Tacoma. It took me about 3X longer than I thought it would (that way with any project of mine it seems). The doors of my Tacoma sound like a BMW when they shut...very solid. I was surprised (pleasantly) at how much better the bass of my 4 door speakers (JL Audio) sounded...not more bass, but tighter and no longer had as many buzzes from door or door panel. I had about 2/3 of a sheet of the Noico left when finished. I would recommend this to a friend and I would purchase again.Tip 1: I DID use weatherstripping foam between the speaker and the door panel in the rear doors--NO buzzes. I ran out and didn't use the weatherstripping foam in the front doors and I have a buzz at higher volumes at certain bass frequencies. Plan to go back and fix that someday.Tip 2: I didn't use the Noico material behind the plastic panels in the rear driver's side where my 10" JL sub is located. Mistake. I now hear buzzes and rattles that I never noticed BEFORE I installed the Noico in the doors...no other changes. What that means to me is that these buzzes and rattles from the sub were always there, I just couldn't hear them as they were masked from similar sounds from the door speakers. Now that I have the Noico in the doors, I CAN hear them. I plan to go back and use the rest of the Noico to deaden those panels one Saturday morning soon I hope.
