Review: effective sound deadening mat - This is my 2nd order for this same material. It adheres well and definately controls sound. Consider 36 sq ft necessary for a proper basic job on a full size car or SUV. I used part of this on a different project, used the rest to perform about a 40% coverage on the inside of the exterior door panels and some basic treatment of some areas in the back of my SUV. Significant improvement. More to be done, I recommend this material
Review: Good product - This material works great and is easy to install. I used a heat gun to heat it before applying to my 75 chevy floor, which made it plyable and easy to mold to the shape of the floor. Holds down great.

## Features

## 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.

### ⭐⭐⭐⭐⭐ A quality, cost effective sound deadening.
*by B***R on June 14, 2025*

I bought a box of this deadener to do the liftgate on my 2015 Jeep Compass. I only have a 12” powered sub, not super loud or anything. I just wanted to reduce/eliminate rattles in the cargo area. I only put this on the plastic lift gate panel, but I might go back and put another layer on the metal. It’s thin enough where you can go over the holes where the plastic clips onto the metal door panel, and then partially cut the holes out to add some extra gripping power for the clips. Just make sure to cut/clear the holes out enough so the clips can go through without bending. But it’s still thick enough to work well to reduce vibrations. Would I use it in a vehicle with a huge system that needed extensive deadening? Maybe not for the main layer. There might be better products on the market for that. But as a secondary or alternative layer for smaller panels or areas? Absolutely. Or if your system is smaller like mine and your sound deadening needs are less severe, this product is just fine for you. Basically, you wanna approach your deadening like your system. If your system is high wattage, high dollar, don’t skimp on your deadening. Get the best product you can. If your system is budget or mid level, this product will work just fine for you if you use it right. I’d recommend buying a set of rollers in the 3 main sizes for sure. Putting on deadening without them is both difficult and less effective. And the different sizes make a huge difference, even for a smaller project like mine.
