    • A royal pain to install ...but excellent adhesion and very good noise/heat blocking properties.

BOTTOM LINE: After looking at the various manufacturers & products here on Amazon I decided to try this SOOMJ sound & heat proofing; it works pretty well and was within my budget. (I've used Dynamat before and highly recommend their products, but they had nothing big enough for my needs that didn't cost and arm & a leg.) For the SOOMJ - be prepared to spend the longer time required to properly, carefully install this stuff - or you'll end up extremely frustrated with a complete mess on your hands. THE STORY: I recently purchased a lightly used 2014 Grasshopper ZTR mower. I had an older model for years and I did the same modification to it that I'd intended for this 'new' one: install sound baffling under the engine hood, muffler shroud, operator's seat & main deck shield in order to quiet down the beast so that I can mow for hours without suffering from noise fatigue by the end of the day. Sound & Heat baffling/insulation can be applied to pretty much anything you're trying to quiet down or protect from heat (or, in my case, both). The SOOMJ baffling arrived quickly, in good shape and well-packaged; no damage to the fairly fragile product inside. THOUGHTS: First impression was of flimsiness. I unhappily discovered that, unlike Dynamat, (which has a spongy yet cohesive cloth-like texture), this SOOMJ matting gives you ZERO chance to nudge it &fudge it during installation. It's like black cotton candy fused to a sheet of thick aluminum foil. Once that brown paper backing comes off, whatever you touch with it - and I mean ANYTHING; intentional or accidental - is glommed with the SOOMJ. It instantly sticks but thankfully is just as easily removed. However the ultra-tacky adhesive sticks to whatever it touches, including your fingers, so you may want to wear a pair of thin surgical-type gloves or else you'll be washing, rubbing & scrubbing that black gummy gunk off of your fingertips for hours. The sound-deadening material itself is fluffy, almost like cotton wadding - but about as cohesive as jello. (Imagine air-whipped black paint and you'll get the general idea.) The style I purchased was in one huge sheet, like 3ft x 6ft. I quickly discovered that it's best to make a mock up pattern of what the SOOMJ will go on, tracing it onto something like heavy butcher's paper or cardboard, then transfer the pattern onto the backing or the foil side, (I used a Sharpie marker), of the SOOMJ. Just remember: preparation is the key! Measure, remeasure and then measure one more time BEFORE you cut. The aluminum heat-blocking part of this product is fairly thin and thankfully gridded (see my pics), which makes measuring & tracing on it much easier. As I said, this stuff is VERY unforgiving. Remember: once you press it, it's stuck there! Installing it was sort of like working with a giant film of partially-liquefied gummy bears fixed to a thick sheet of Reynolds Wrap. I got better at it as I went, but regardless this product scored zero points from me for user-friendliness. LOL But it's the end results that count and so far I'm quite pleased. I placed it around the rear engine/exhaust guard, mere centimeters from the muffler, and after over a month of mowing (in temps soaring close to 100 degrees) the SOOMJ has stayed intact, with no signs of breakdown or decomposition despite the intense heat generated inside that compact space over the coarse of a long hot summer's day. The install under the seat and on the underside of the primary deck shield are also holding up very well. The noise of my Grasshopper 930D has been noticeably quieted down. It's still loud make no mistake, but it's more like a Piper Cub now than a 747. With a few reservations I would definitely recommend SOOMJ to others. Just take the mistakes that I made to heart and hopefully you'll avoid them yourself - IF you decide to buy this product. ... show more

So far so good, I used the old heat shield as a template to cut the new insulation before removing the paper backing. Make SURE to get aluminum tape to finish the edges if you want this stuff to look good and last, I used ADHES 2" wide heat resistant tape that I also ordered from Amazon. It worked perfect and was very thin and formed well. If you don't use aluminum tape on the edges I don't think that you can get a nice cosmetic finish, in addition I believe that the wind would eventually work under the adhesive of the insulation, get debris on the adhesive and eventually cause it to fail. In my photo you can see that I was fairly aggressive forming it to the shape of the underside of the hood, this causes the aluminum backing of the insulation to crack where you are stretching it, this was expected and easily repaired by adding some additional foil tape where I had cracked the covering. I will now be doing the engine cover on my boat and the firewall in another vehicle. Five stars, exactly what I needed. ... show more

This stuff seems to work good. If your looking for a one source for heat and sound then this is the way to go. It is a little think but it works very well for noise and heat. I’m running a big block and this did great on the interior firewall and floors and trunk .. quieted the car right down and made it a lot cooler in the summer. Try it out only down side I can say is it is think ... show more

    • Strong adhesion and close fitting, perfect for boat use
Size: 78" x 39" (21.13sqft) Color: 10mm/394mil
I used this product inside the fiberglass enclosure of my engine compartment that sits above the deck and doubles as a seating area. I needed to reduce the noise. The adhesion was better than expected, in fact i dont see this coming off unless you were to scrap and use some pretty tough remover. The depth was just right as i could not have the product hang into the engine area, needed a close fitting buffer, yet still needed a sound barrier. This definitely helped. Good product and price when i looked around at other comparable marine application products. ... show more

This product was used in a 1971 Corvette to shield the firewall and transmission tunnel (both inside the car and between the transmission and a chassis). It was able to reduce but not eliminate the significant heat which pours off the engine. Not sure about the noise. The vette is made of fiberglass and noise ... show more
