Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product. Review: Awesome product 👌 - I love this stuff. I use it alot. Sticks great Easy to use Molds super easy Really helps with sound. Great product. I wish I could get sponsored for this product on my projects.. ## Features - Very sticky self-adhesive 80 mil automotive butyl and foil sound deadening! It is user-friendly viable material suitable for DIY installation. KILMAT is really efficient and easy-to-install. - * Now the material is 1,5 times thicker that will get you 1,5 times more effective insulation. The thicker the material the more performance you get! - * Automotive self-adhesive insulation consists of butyl. KILMAT sound deadening has a total weight of 0.5 lbs/1sqft.

KILMAT 80 mil is light weighted sound deadening material! - * Audio insulation KILMAT has a special indicator as to if it is installed correctly. The special embossing on the foil must be rolled out till it is plain smooth, then you'll be 100% sure that the soundproofing is set correctly and professionally! The sound dampening material comes in handy size sheets which make it easier in terms of cutting and installation process! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B082Q2J2T4 | | Best Sellers Rank | #146 in Automotive ( See Top 100 in Automotive ) #1 in Automobile Insulation | | Brand | KILMAT | | Brand Name | KILMAT | | Coverage | 18 square foot | | Customer Reviews | 4.8 out of 5 stars 26,052 Reviews | | Item Dimensions L x W | 15.7"L x 9.8"W | | Item Thickness | 80 Mils | | Item Weight | 4.4 Kilograms | | Manufacturer | KILMAT | | Manufacturer Part Number | KLM8018 | | Model Number | klm8036 | | Product Dimensions | 15.7"L x 9.8"W | | Recommended Uses For Product | Car soundproofing | | UPC | 857195006450 | | Unit Count | 1 Count | ## Product Details - **Brand:** KILMAT - **Item Thickness:** 80 Mils - **Manufacturer:** KILMAT - **Product Dimensions:** 15.7"L x 9.8"W - **Recommended Uses For Product:** Car soundproofing ## Images ![80 mil 18 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening - Image 1](https://m.media-amazon.com/images/I/71QsYM0QNtL.jpg) ![80 mil 18 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening - Image 2](https://m.media-amazon.com/images/I/4113E5xboUL.jpg) ![80 mil 18 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening - Image 3](https://m.media-amazon.com/images/I/71-aNbPgWeL.jpg) ![80 mil 18 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening - Image 4](https://m.media-amazon.com/images/I/71d1zkelTQL.jpg) ![80 mil 18 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening - Image 5](https://m.media-amazon.com/images/I/6140bI92XiL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Could anyone post a picture of the installed insulation?** A: I'm pure sure anyone could do it **Q: How many boxes i need to cover my ford transit 350 extended cargo van, but in a very strategic way.** A: You would need 5 boxes of material to cover the floor (apply long narrow strips in between the ribs), double the layer on the rear wheel wells (from interior side), apply long narrow strips to the roof from the interior side and apply some to the wall panels, specifically to the sheet metal tiles in between the ribs-columns. You would need an additional box for the cab if you decide to soundproof it as well. It is worth mentioning that you'd need to do 100% coverage on the floor, roof if you are after maximum effect as those are the most important areas. Make sure to roll every piece of it with a roller and clean/degrease the surface prior to installation. Wear gloves! **Q: Would this work under the hood?** A: Kilmat has a working temperature from - 49 degrees to 212 degrees F with allowance for only short term heating of up to 392 degrees F. We recommend using our material when installed under the hood in combination with a hood liner type of material (acoustic foam) to protect it from excessive heat (if any) and to add the additional insulation. The first layer that goes on a hood metal would be Kilmat 80 mil material The second layer on top of Kilmat 80 mil would be hood liner type of material. We are sorry, but we do not carry hood liner materials. **Q: I have a 1968 Mustang the exhaust is pretty loud can I double the insulation how much less noise will this have on exhaust** A: The exhaust on my '79 Camaro is pretty loud too behind 400hp. This 80mil should be thick enough. You'll want to cover 100% of the floor board and make sure you cover under and behind the back seat and also up the sides of the inner quarter panels. I used a precut heavy underlayment layer on top of this Kilmat, then the carpet of course. The layers I have tamed the exhaust decibels inside the car tremendously. My car's interior was never this quiet before the restoration. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great sound mat for the price! *by M***E on December 3, 2025* This is a good product.
