Eastwood sound deadening mats - 04/24/13 04:51 PM
Eastwood sells an inexpensive version of the Dynamat product. I've read the reviews and it seems that they work good but melt under high temps? Anyone used them? What's your experience?

I have heard mixed opinions on the Eastwood mats. You are correct, the problem is the ability to withstand the heat Dynamat does. I ended up using the Dynamat because of the fact I have used it before and works well. I kinda go by the, "You get what you pay for." If the mufflers are close, or something that makes a lot of heat, MAY be a problem. I will be watching to see if anyone has used it before.

I am also interested in adding some type of sound deadening mat in my car. I searched for a thread I started sometime ago regarding the same thing, but gave up when I couldn't find it.
My 70 Charger is fine for short trips but once you drive for more than 45 minutes to an hour, the noise and drone tend to wear on me. I am leaning heavily toward Fat mat. Amazon sells a roll that is 1 ft wide, 50 ft long and 80 mils thick. $93. I figure that 2 rolls will cover the whole floor, package tray, trunk divider and behind the door and kick panels. If it only reduces the interior noise by 15-20%, I'd consider that a win.

The cheapest way that I know of is to use Modified bitumen rolled roofing and a layer of bubble foil insulation. Find a commercial roofer and ask to buy some scraps or cut-off ends from a roll. Or buy a whole 39"x 33' roll at a commercial roofing wholesaler for about $80. The bubble insul is about $14 at Menards.
I did this on my 67 Olds 442, and was amazed at how effective it was. Much quieter and cooler than before. I didn't even cover the hump or the doors. I just made sure to get the firewall really well and the floor pans. Since it is a convert, I din't know if I would notice any sound deadening because of wind noise, but it was very noticable.

The roofing type matting is a cheap alternative but every testimonial that I have heard involves an odor of the tar imbedded in the mat. Some say it went away within a few days, others say it is still there after a year. If you don't have an overly sensitive nose, this may be a great option.

I just used the eastwood mats...Did a complete floor...As with all of these types of mats they're heavy !!! Added alot of weight quick...So far so good...No odor with the mats that I could tell and the dual exhaust has'nt created any melting issues I'm aware of...I did break the cheezy roller supplied with the kit in short order and stepped up to a better one...And the edges were sharp and unforgiving during the install...
Eastwood just had a sale on the mats...

I did the "Fat Mat" stuff off ebay, covering the complete floor, hump, firewall, rear wheel well part that is in passenger compartment, and the package tray . . . WOW !!! Can certainly tell the car is quieter inside, and you can barely hear the wonderfull exhaust sound . . . so, I say it is worth the effort to install and the little bit (ok, maybe more than a little) of added weight !!!
I also noticed the heat was way down too !!! I had run the engine without the mat installed and noticed how warm the tranny tunnel got - nothing now with the mat installed !!!
I think for the money, the fat mat stuff, is worth it !! As far as it melting or coming unglued . . . can't say as I have gotten things that warm !!!
Cheers
Mark

I know some here are weight consious. A good place to look for lightweight sound deadining products is the aircraft industry. Costs more but in some cases definitely worth it. Just some food for thought.

2 boxes in my dart convertible. I did inside doors, floors firewall, inner rear quarters, basically everywhere i could. No problems melting. Im in az, and been out in 110F with the asphault temps likely in the 150s. AC kept the car reasonable comfortable. As far as sound deadener quality, worth the weight. Mine is a cruiser so i wanted comfort over power. Ive got heat shields on the mufflers and so far no melting of the insualtion. Stuff is easy to work with, and makes a world of difference.
I wouldnt definately do it again.

I used this in my Challenger floor. Didn't add too much weight but made a difference in db in the cabin. Good "bang for the buck"...
