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.
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.

## Questions & Answers

**Q: Does Kilmat acts as a heat barrier?**
A: Kilmat 50 mil does reduce the noise, rattles and vibrations of the metal of the car. It does possess thermal insulation properties as well but to significantly lesser extent. Its primary designation is vibration control.

We recommend you to look for some closed cell foam materials for heat insulation.

**Q: Will 50 sq.ft. cover the full trunk of a 78 buick regal**
A: 50 sq ft is a 10x5 area so yes it will. You should have plenty left over for another area

**Q: For application to underside of car hood, should I also use a spray adhesive?**
A: There should not be a problem adhering Kilmat 50 mil to the underside of the hood without using additional spray adhesive, thus we do not recommend any additional spray adhesives.
Make sure to clean and degrease the surface prior to installation.

**Q: If I'm taking the carpet out of my vehilce to put the Vinyl flooring, would this be going under it ?**
A: I assume that you are talking about replacing your auto carpet with a factory preformed vinyl mat. Regardless, this product will assist in "quieting" down the road noise and heat from your vehicle. Yes, it should be applied directly to your stripped and clean floor board to get a better adhesion. After installing, lay your new vinyl mat down and secure at the door sill. I used this material in the roof, inside the doors and the back wall of the cab of my 61' Ford unibody pickup. It's amazing the difference how effective the KILMAT performs. I highly recommend it !

### ⭐⭐⭐⭐⭐ Order plenty, youll love it! Excellent product.
*by T***N on November 16, 2025*

This is an excellent product. Very easy to apply and user friendly. Add layers to build up areas easily. I used acetone to prep the area and had excellent adhesion. No piece is wasted. You can add the smallest scrap to anywhere and roll it in. The foil is very strong and pliable. Easy to go onto curves. It is a perfect product. Excellent sound deadening results.
