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

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.

Just as described by seller great product easy to work with first time installing the sound deading product no issues sticks extremely well with roller cuts easy with scissors once installed you can hear the difference quiet awesome product great price also purchased the insulation foam padding

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!

It works and is good quality for vehicles and more. Sticks great easy to use

Great product if you want to reduce the road noise in your car while driving. Was commuting on the highway about 1hr each way everyday in a 2010 Kia Soul and the road noise was killing me. Ended up buying a db meeter and found cabin noise to be +/- 80 db at highway speeds. Had to have the radio on nearly full blast to listen and hands free phone calls were nearly impossible to hear. I used the sound deadening material on all bare metal areas I could access, full rear trunk, under rear seats, front firewall, and all four door panels. The difference it made was incredible and worth every penny spent and minute installing. Dropped the db down to 73 db in the cabin at the same speed. Could finally have a conversation without shouting and listen to music on low. Honestly the reduction in noise saved my sanity. Installation is straight forward, just need a few tools to access the panels you want to cover, a box cutter and/or scissors, and a hard rounded surface to press it on. I do recommend wearing disposable gloves as well, as the sticky material is hard to get off by design. Will be using on all my cars going forward regardless of make or model to reduce every db I can.

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.

This stuff is really fantastic, and is a real bargain at this price. The only issue that I ran in to was that one of the sheets had 3 long, wide gouges. It may have happened during packaging. I planned to cut one sheet into tiles to put inside of a hollow rail under the rear deck, so fortunately it did not hold me up. The main reason I purchased this product was to reduce the drone from the Roush exhaust on my 5.0L Coyote. It accomplished that for sure, reduced road noise that came up after some suspension mods, helped to really clear up the sound of the subwoofer in my trunk, and reduced rattles in-car. This is not a magic bullet to creating a silent car interior, but will put you pretty far along the path to a quieter ride. Look into some quality closed cell foam and mass loaded vinyl if you're wanting to get as quiet as possible. For those of who you have not used sound dampener products before, these are typically most effective for reducing structure-born noise by preventing resonance in body panels. You do not have to have 100% coverage to be effective, though I have always found it to be beneficial to have 100% coverage in the trunk or other highly resonant areas(wheel wells, door skins, in some cases the roof, etc.). I would also recommend installing this stuff in doors, behind sail panels, on or below rear decks, etc.- basically any panel that a speaker mounts to; this will reduce the energy your speaker wastes resonating that panel, and make your speakers have a much more clearly defined sound in the mid and low range. I would highly suggest that in addition to whatever roller you get, you use the knobby/round end of a screwdriver to help properly seal the dampener. Especially in tight areas or if you lay the product in a tiled fashion. Also, if you have not worked with a similar product before- disposable nitrile gloves work far better than basic work gloves; your hands will be able to work with greater dexterity, you will not get cut, and you can avoid black, sticky smears all over your work gloves.

I’ve never installed Dynamat, nor experienced its performance, so I can’t speak to personal difference between these two, though one can speculate that Dynamat is objectively superior quality so the performance should be better. I can, however, confirm without a doubt that this made a noticeable difference in *my* car. I drive a 2015 Mitsubishi Lancer ES. The vibration dampening in these particular cars is virtually non-existent. My doors actually feel and sound “premium” when I open and close them, not hollow tin cans like they did before. 36 sq ft was enough to do all 4 doors, the surface behind the rear seat head rests, and the trunk lid, with a few scraps left over. My speakers are JBL GX602, and a cheap-o Walmart sub I got as a placeholder while I finish building the real deal. The sound difference is actually remarkable. The speakers sound much clearer, but the bass was the biggest change. All the rattles and vibrations that existed before are now gone, and the bass is so clean and punchy, even for such a cheap sub. I drive for Lyft, and I had two passengers complement how “clean” and “comfortably loud” my music sounds (the second passenger actually asked me to turn it up because I was listening to Parquet Courts!). Can’t wait to hear the difference with a quality sub setup. I’m very satisfied with this, especially for the price. I think people need to set their expectations, they’re expecting this to perform like the significantly more expensive Dynamat. Based on the public consensus on Dynamat, it’s very effective and hard to beat. That performance comes at a premium, and honestly, I think most people would be satisfied with the performance per dollar that Noico offers. Also consider your specific car. If it already has decent vibration dampening, then you’re not going to notice as much of a change as someone like me whose car had virtually no dampening. If you have two enormous subs that your neighbors down the block can hear, then don’t expect this *alone* to work miracles. All in all, it does what it’s supposed to do at *this* price point, and at this price, I don’t think anything can outperform it, so for that, I’m giving it 5 stars.
