Siless 50 mil 26 sqft Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material (26 sqft)

This is an excellent product, especially for price point. The material itself is heavy enough, good quality aluminium backing on the facing side, easy to cut and mold. The adhesive is quite sticky and I had absolutely no issues with peeling or delaminating once applied to bare painted sheet metal inside truck doors. The difference in road rumble was pronounced, a 2014 Frontier Pro4x is not a Cadillac XTS and does make some noise, with my new Morel 6.5" separates I did all four door panels quilt-work layered (overlayed) up to three layers thick around the speaker areas themselves. With no new amplifiers or head unit the speakers are quite clearly audible and clean at two to three clicks lower on the volume control, and clarity and definition is improved. Dynamat-type materials recommend at least a 30% panel coverage for effectiveness, I did the entire door so 95%+. Highly recommend and a great price point, effective and economical.Update, 19 May 2020I first ordered some Siless mat in June 2018, it worked very well in my 2014 Frontier's doors and I ordered more for my rear cab wall and floor. Ended up installing that pack in my wife's new-to-us 2012 Toyota RAV4, but needed some more. Ordered two more packs to do the cab wall and floor as originally planned and to add some more areas and thickness to the RAV. Order arrived today, without going into any major details that would set any unreasonable future expectations, David from NY went above and beyond, the very definition of Customer Service, I would give them 6 stars if I could. A fantastic company to deal with and processing and shipping was very quick, more than satisfied. Please support this outstanding company.

23 sqft gave me more coverage than I expected. My doors are a pretty decent size I guess, Toyota Tundra. I didnt do a 100% blanket coverage of the exterior skin and the interior panel, I used the method that can be found on "soundeadner showdown" (sp?).I really liked the packaging. A box with plenty of, well, packaging to protect the smaller box inside. All the sheets were in new like condition.As for how it compares to other more popular brands, e.g.. Dynamat, Roadkill... And another similar one that's name I can't recall... Mmm, I really can't say cause my installs with those brands I wasn't satisfied with the quality I applied it with. You know, didn't really have as much as I would of wanted.... Due to cost.. And honestly not really understanding how to determine the areas of most importance. Little things like that.I did notice an improvement though and if the higher cost is within your budget it may be worth it just for the piece of mind knowing that those brands are top tier.But!!! I now also feel confident in some of these lower prices competitors available now. I got the results with this brand that I was expecting and still have a few sheets left to use later when the opportunity is available.This stuff applied just as well as the others. The prep that is given in the directions is the same as the others. Clean, clean again, dry, apply with roller.In conclusion, I'm sure cdl tiles and Dynamat extreme produce the best results but I don't think the difference in their cost vs brands like this ones are proportional compared to the difference in effectiveness.I'm glad I saved some cash and now feel comfortable knowing I can get these products at a respectable cost that meet my needs.

I like the price for the sq ft received. It looks good, looks like the Kilmat I've used. It installed easily. Seems like it will work.ONLY drawback is that when I put a sheet of the Siless 50 mil next to the Kilmat 50 mil it is obviously not as thick as the Kilmat. Also, when I installed it, if you tap on areas with the Kilmat and then opposite areas with the Siless (as seen in my pic) there is a noticeably audible difference. The Kilmat had a flatter sound than the Siless.

THIS STUFF IS GREAT! 1ST TIP: GET THE ROLLER!!! I USED A LAMINATE FLOORING ROLLER THAT WORKED IN THE END, BUT A SMALLER ROLLER WOULD HAVE HELPED IN THE CURVES AND CORNERS OF MY FLOOR PAN AREA. MAKE SURE THE TEMPS ARE AT LEAST 60-65 DEGREES AS IT BECOMES MUCH EASIER TO MOLD AND WORK WITH. ONCE THE SHEET COOLED OFF, IT BECAME PRONE TO TEARING THE FOIL. WILL DEFINATELY BUY THIS AGAIN IF I EVER DECIDE TO RUIN MY LIFE WITH PROJECT TRUCK AGAIN!

Bought product to reduce road noise due to taking out headliner. Great alternative, less noise in Jeep xj. Stuck well. Even used magnets to help me install. People recommended a roller, but I used a microfiber cloth, worked fine to get in the creases of the roof line. Made music sound cleaner. Make sure to check out their website for a variety of products that I only found out about with the QR code in box. Buying again to reduce vibrations in my Subaru from 2 12” subwoofers. And recommend to all
