Review: Excellent product at an affordable price - Product is excellent in noise reduction, thermal reductions, and it’s easy to work with. It is aluminum backed so when cutting you can create sharp edges, just be mindful of that. The adhesive side is great as it sticks well but is also forgiving if you need to adjust. Very pleased with the results.
Review: Great sound mat for the price! - This is a good product. 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.

## Questions & Answers

**Q: Can this hold up to Arizona heat?**
A: Please note that Kilmat is designed to reduce sound and vibro insulation of metal surfaces. It has some thermal insulation properties but for the less extend. 
Kindly note that Kilmat material has a working temperature from - 49 degrees to 212 degrees F with allowance for only short term heating of up to 392 degrees F.
Let us underline that Kilmat cant be installed in the engine compartment, only under the hood in combination with headliner. 
All of our materials should be installed from the interior (cabin) side of a vehicle
No exterior application allowed!

**Q: Restoring a old car pulled up all the mastic from original but cant get it all  if i cannot get it perfect cleaned up will it still be ok to put down**
A: The idea of the sound deadener is to bond it without voids to the metal. This keeps the metal from vibrating. A little mastic should not be a problem.  Just make sure you press out all the voids.

**Q: Can this go under the hood without melting?**
A: Kilmat 100 mil material is mainly intended to reduce noise, rattles, and vibrations of the metal of a vehicle. And it's not intended for thermal insulation and shouldn't be used as a heat shield.
It has a working temperature from - 49 degrees to 212 degrees F with an allowance for only short-term heating of up to 392 degrees F.
Kilmat 100 mil must not be installed in the engine compartment(except for the underside of the hood).
The temperature under the hood might be really high. For this reason, if the material is being installed under the hood, we normally recommend using Kilmat 100 mil in combination with the hood liner material.
The first layer that goes on a hood metal would be Kilmat 100 mil material
The second layer on top of Kilmat 100 mil would be a hood liner-type material to protect it from excessive heat.
We are sorry, but we do not carry hood liner materials, but one can easily find them on the market.

**Q: Is 100mm good  for a sound system or what size mm do i need?**
A: Works good for me. Can always add more layers to own preference. Honestly any sound deadening better than nothing

### ⭐⭐⭐⭐⭐ Awesome product!!!!
*by A***R on August 24, 2025*

I recently purchased the Kilmat sound deadening mats, and they work exactly as advertised. The material is thick, durable, and easy to cut to size. The adhesive backing sticks firmly without peeling up, and the foil surface adds extra heat insulation. Installation was simple with just a roller, and I noticed an immediate reduction in road noise and vibrations inside the vehicle. It also gave a more solid feel to the doors and panels. Overall, this is a cost-effective alternative to higher-priced brands, offering excellent soundproofing and thermal insulation.
