  • High quality, super sticky, very effective
Style: 30 sqft
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. ... show more

  • Nice and thick. Very shapeable. Sticks great. Big improvement.
Style: 30 sqft
Used on an empty trunk. Had zero carpet, padding, nothing. My car had tons of vibration and road noise coming from the trunk area. I lined the entire bottom, and floor area, basically everything but the wheel wells. Even did the underside of the package tray. The volume of noise is night and day. I’m somewhat surprised by how much quieter it made the inside of the car. I bought the thicker MAX version and I’m glad I did. Grid pattern makes it easy for cutting straight. Cuts with a razor knife or heavy duty shears. No smell. Super thick. Easy installation, peel and stick. Can smooth with fingers or use a roller if you want. I will say be careful with the edges of the foil top liner. It is SHARP!!! I didn’t use gloves and got about 20 paper cut like cuts on my fingers. Would purchase again. ... show more

  • Easy Installation, Amazingly Effective
Style: 30 sqft
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. ... show more

  • Impressive Stuff
Style: 30 sqft
This sound deadening material works amazingly well. Easy to work with. The adhesion is perfect. Not so sticky that it is a pain to work with. The adhesion is just right and the thick textured foil is easy to form and works as a nice guide for cutting. No weird smell either.

  • I bought the 120 mil. It does seem like 120 mil as compared to Noico 80 mil.
Style: 30 sqft
I like it, it worked great. It does not seem to have any bad smell, although it has a slight scent if you put your nose right up next to it (but all brands are like that). FYI if you don't already know, most of the noise comes from the wheel wells so DO THE WHEEL WELLS FIRST! And you probably don't need to do anything else besides that because 90+ % of all the noise comes from the wheel wells area (from road noise as the tires roll on the road and vibrate the air). Don't bother with the floor, the doors, the trunk, or the roof unless are looking for that last 10% of improvement because you are a car stereo enthusiast (or you like to waste money and do extra work LOL). I put multiple layers of butyl sound mats totalling about 1/4 inch on my four wheel wells (plus about 2 inches farther around the perimeter of the wheel wells), and just a little bit on the front floor (driver and front passenger floor) but I probably didn't even need the floor. The wheel wells made a HUGE difference. My car had NO sound insulation whatsoever and was horrible to drive on the highway, now it is PLEASANTLY QUIET and a joy to drive. I actually also put alot of sound mats on the middle and back floor, but it didn't make any difference so I removed it. So I recommend a minimum of two 80-mil layers on all four wheel wells, but preferably four layers to total about 1/4 inch. Or use three layers of the 120-mil mats. The more the better, but it seems to me that 1/4 inch is enough to bring the noise down to a luxury level. ... show more

  • Great deadener
Style: 30 sqft
Ill have ordered this multiple times over the years and recommend it to anyone, I would have left 5 stars, but the print I received on my last order was faint as could be and my ultimate goal was to show off the deadener but with the print that way I'll have to end up covering it up. It's a nice easy install btw, I've even installed in the winter with the use of a heat gun below freezing outside and it's still able to be applied. No odd odors like some foam ones I have used in conjunction. ... show more
