Great upgrade for your older project vehicles. Easy to install and cuts down considerably on outside noise from engine and exhaust. Also a good heat insulator. 2 boxes are enough for a single cab truck. Can be double layered for further insulation and noise canceling. Buy the rollers to add with install. Save money compared to Dynamat. Would reccomend using gloves during install, foil backing can easily cut your hands.

These tiles are very easy to work with and the graph on the backside make cutting and trimming a breeze. They stick well but allow you time to manipulate and adjust. I was very pleased with this product overall and as a mechanic with 30 plus years experience I would highly recommend

I have a 1937 IHC Truck. took out the wooden floors and installed steel. Super noisey now. Installed these mats and the deadening qualities are fantastic. Fairly easy to install. cutting them is similar to drywall. score the aluminum fold, cut the black sticky stuff with a razor. Very easy install.

The Silass mat works awesome! I picked up 3 sets but doubled up on the floor so I’ll need another to finish the little bit left. It made my Jeep Cherokee XJ sound like a new car. It was noticeably better insulated and the sound is so much better. The noise is more dense sounding instead of rattly which I love. It sticks like crazy! And it was super easy to install and trim when needed. Wish I’d have put this in every Cherokee I’ve had.

I used this product for sound insulation in my motorhome, in which the V10 engine is just below and between the front seats. It was very hard to carry on a conversation while cruising on the highway. The Siless 3mm sheets are a very manageable size and easily cut with an old pair of scissors. They are quite sticky once the backing paper is removed (as you'd expect), but not so sticky that you can't slightly reposition them before rolling. Once you roll the material, it is stuck for good. I installed the Siless material on the engine cover, the floor under the front seats and the dash panels that had the engine compartment behind them. The noise reduction was very noticeable, even at idle and on surface streets and it's now possible to converse on the highway.

As long as the surface is thoroughly cleaned, these mats will stick to just about anything. They provide my car with a tremendous amount of sound dampening and have made riding in the car 10 times more enjoyable.I drive a Toyota Yaris and although the engine is built like it's meant to last forever (imagine that), the rest of the car is not of high quality. Which means we used to get A LOT of noise coming from the road, other cars, etc. After I installed these mats which, by the way, I wasn't able to install on every surface I wanted to install them on (due to lack of tools to be able to disassemble certain parts of the interior), the noise coming from outside the car is nearly completely gone.I covered the underside of my hood, the entire interior part of the hatchback, most of the floor in the trunk / spare tire well, and the entire interior side of the doors. The parts I couldn't get to (or didn't want to) were: the ceiling, underneath the driver & passenger seats, behind the dash and the floor for the 2nd row seating. As you can see I left a lot of surfaces untreated with this product AND STILL it blocks most of the sound.To note: people recommended getting the roller tools to help install these mats. I got a few of them in different sizes and they worked O K. Not because of the quality of the tool but because some places you need to install these mats in don't have enough clearance to use the tool. That being said, for the larger surfaces, the roller tools help a lot. Also I found it very beneficial to use aluminum tape while installing these. The tape I used is specifically designed for materials that undergo high temperature changes (like your dryer vents, etc.). This wasn't because the mats were not sticky enough but because there were some places I installed the mats with small gaps between them.I'd also recommend getting some kind of fluffy insulation-type material for large spaces that need noise dampening. Rock wool, for example, worked great for me. As an example, the interior sides of the 2nd row seating walls had large spaces between the plastic interior cover and the metal part of the car wall. I'd install the mats on the metal but was left with 6" - 7" of space between it and the plastic cover. I chose to fill those spots (and spots like it) with insulation which provided EVEN MORE noise dampening.

I used 2 and even 3 layers of this in some areas and my car hasn't been quieter. I bought it to prep for a complete sound system overhaul. I can confidently say it was well worth it even with some to spare and give to friends. it was hard to cut but with non-stick siccors with adjustable blades really helped with the cutting. easy to stick and rearrange if needed but the foil would split if enough of a gap or lip was present. I bought a Roller but if left in the sun it'll soften right up.

Used this product to deaden a pair of large speaker cabinets, great product to work with, used a pair of metal sheers to cut and trim the material which worked well, cleaned the MDF and it adhered very well too. The speaker cabinets sound much better now, when knocking on them they sound much less empty or hollow, playback sounds cleaner and has less echo as well. Overall very pleased with the outcome.For application I also purchased a metal roller which was a must, I couldn't imagine applying this much by hand alone.

This product is easy to cut and lay out to fit your space. The paper backing makes it easy to apply the sheets as they are laid in place, while avoiding air pockets. I highly recommend wearing clothes that you don't mind getting dirty. And work from far points to near points in order to avoid contact with sheets already put in place. The butyl can be pressed up between sheets and stick to clothing. I am pleased with the end result. My 2020 Ioniq is more quiet in the middle and upper frequencies so that I can listen to the radio comfortably.
