Car Sound Deadening Material Mat - 197 mil 8.7 sqft Auto Audio Deadener Foam, Sound Dampening and Heat Insulation for Truck, Vehicle

Why did you pick this product vs others?:Product works well. Was the right size sheets for what i was working on. Used to insulate cargo floor area in an older Jeep Grand Cherokee, i used a little fabric stick spray first , but it wasn't necessary, as the self sticking sheets fastened well. This made a noticeable difference in road noise reduction. I would definitely buy again if i decide to do more interior floor area later..

Used this on the roof and door skins of my 2019 RAV4 to reduce vibration and rattles etc. Works great. Removed the headliner and installed directly to the roof then behind the b pillars and inside the doors. Now outside noises are lessened or at least more dulled. Definitely made my entry model feel more premium 🤣

This KOIKEY sound deadening mat works great. I used it on my work compressor, and it significantly reduced both vibration and noise. The foam is thick (394 mil), and the adhesive backing is strong—it stuck well to the metal housing. It also offers some heat insulation, which is a bonus in a hot work environment. Easy to cut and shape, and ideal for vehicles, compressors, or shop equipment. Definitely impressed with the results.Q&A Section:Q: Can this be used outside of cars, like on tools or machines?A: Yes, I used it on a compressor and it worked great—cuts noise and vibration well.Q: Is the adhesive strong enough for rough surfaces?A: Yes, it sticks firmly to clean metal and plastic surfaces.Q: Does it offer heat insulation too?A: It does provide some thermal insulation in addition to soundproofing.Q: Can it be cut to custom shapes?A: Absolutely—easy to trim with scissors or a utility knife for tight fits.

Easy to apply, very sticky when you pull the protective layer off the adhesive side. I advise fitting and cutting before removing the protective layer. I lined the spare tire area of my suv and it worked great. Also can be applied to round surfaces.

I installed it but haven't tested it yet. Very sticky. Nice stuff

Not what I was thinking. I've used insulation like this that was composed of heavy material, this one is not. This product must be for boats or airplanes where weight is a primary consideration and noise is not a problem. This is too light to have an effect on vibration or road noise. Absolutely zero difference. Anyways, I have both front doors full of the stuff and I'd pass if I were you.

These were perfect for what I needed them for. I have a Honda Fit that, by the factory, has near no sound insulation and is terribly loud when driving down the road. These were thick enough to be effective but not so thick that it kept my interior trip panels, headliner and console from obstructing them from going back on. The pill-and-stick feature was easy and fast. The paper backing was not only easy to remove but gave a surface to draw on when transferring over a pattern to cut out. Plus, they cut super easy with a good pair of all-purpose scissors, not once clogging up the blades with adhesive residue. The adhesion also seemed super strong even on the underside of my roof sheet metal. After using these over a good portion of the inside of my car, concentrating above the exhaust, the firewall and the roof sheet metal, my car is not only much quieter, but it now also gives the impression of a more solid driving car. I wasn't expecting that and it was a bonus. If you have the knowhow and time to take apart an interior to get to the car's interior sheet metal. I highly recommend these stick-on insulators. But I cant give feedback on engine compartment or outside of the interior use. I have no experience if they'll hold up to direct heat or moisture.,...For what I used them for.... 5-stars all the way

I had a heavy duty stainless steel sink installed as part of a new countertop. However when they install the sink They used a silicone adhesive for the sound deadening mat under them sink but forgot to remove the silicone facing. So the sound deadening Mat did not adhere and stay attached. When removed there was a noticeable difference between the side of the sink with them deadening mat and the side without the deadening mat. I tried every glue instant grab possible to no avail. Then I found this item on Amazon. $14 for 6 or 8 pieces but I only needed the one and it was worth the price many times over if I had just had it to begin with. I use the old Matt as a pattern cut it out with a good pair of seamstress scissors tested the fit. Remove them film from the glue halfway touch the deadening mat under the sink then remove the rest of the mat and attached just by pushing it tight to the under sink. What an amazing difference in sound hearing the water hit the stainless steel sink in just a nice soft sound. That whole process took about 1 year with no help from the countertop firm. They offered no help or suggestions. It's one of the few products like other products you can find on Amazon. Fast delivery to boot. That's one thing we could never do without the internet.
