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

Seem to work well

Excellent alternative to the big name sound deadener. This product does not give off a foul odor like other less expensive sound deadener.

This seemed to help make my small Yaris iA quieter by adding it to the rear of the car, around the wheel wells behind the back seat, and the trunk, especially under the spare tire. I had some issues with cutting it every now and then, as the foil part would separate and crinkle from the adhesive foam layer. Other than that it works seemingly well, definitely has some weight and effectiveness to it by reducing the tin sound of the sheet-metal as well.

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. Its highly advised you purchase a wood roller. I attempted to push it flat and flush by hand. It wasnt long before I noticed LOTS of small but annoying cuts on my fingertips. Use the wood roller if you dont 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 wasnt 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 youre flattening the mat, the black glue expands about 1/8-inch beyond the mat, letting you know that its going to hold firm. In short, Im 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.

I was very impressed by the thickness of the rubber and foil backing on this product. It did an amazing job of reducing the road noise in my cargo van. I installed it on a hot day and it very easily stuck to the metal panels. Make sure its where you want it to be when applying it because once you use a roller to press it down its not coming off without a fight.

Very nice stuff easy to cut and apply. Be warned this adds a ton of weight to the car

Im using this in my 66 Chevy truck to kill the tin can drone it has. Did the firewall, front floor pans, and the inside of both doors (both panels on each) with one box. I went ahead and bought another box to finish out under the seat and the back wall of the truck before I start making a sub box. Easy to cut, stickier than all get out, and no smell so far. Worth the money and time. Doors close with a thud now rather than a clank.

Very pleased with the quality and overall performance of the product

Cheapest, best, sound dampener out there. Works just as good as the big names and applies just as easily. My entire interior is covered in this and their foam insulation. Almost a Lexus inside now. Save your money and get this over the others.

Easy to work with, quality product. Recommend!
