Sound Deadener?

Postby mpdcop » 02 May 2011 10:16

Has anyone ever used Dynamat, Eastwood, Fatmat....? Which product is better? I realize that Dynamat is popular and it is very expensive. What have some of you used and what do you like better? thanks

Roll on roofing tar. Called 'Torch On' in some places. About a meter wide and 1/4 to 3/8" thick, absolutely dry to the touch, has clear plastic on one side. Install with plastic covering upward and replace carpet on top of that. Looks like rubber sheeting, cuts with tin snips or knife. For corners or odd shape lumps or depressions in floor warm with a propane torch to soften and mold into place. You can melt two pieces and they will 'weld' together. I got all I needed for asking at a construction site for the roll ends. Roofers like to use single pieces where possible and chuck shorter lengths.

Dynamat is good stuff, we've tried all the brands and Dynamat is by far my favorite. Nice and thick. We even put in on the roof before the headliners go in. Road noise gets annoying.
I liked Hainz better...... Can we trade back?

Ok, thanks... I kinda figured Dynamat is gonna be the best.

I did find a site www.streetsideauto.com that sales the Dynamat brand at a reasonable price... Just in case anyone is interested.

There is a site where many were compared. I can't find it now but I might have it aved at work. It was good, with some good testing, and many brands were tested. Sorry for the teaser, hopefully I can come through with a link.

I believe S15DET is referring to sound deadener showdown. Great read. This actually influenced the purchase of my sound deadener. I used tiles from second skin audio and bought the foam and mass loaded vinyl locally.

Hear is the old link http://www.dctra.org/files/1974_TR6_Car ... owdown.pdf

This was actually version 2. I had also read version 1 but can no longer find it. The guy who did the original comparison now sells his own products and has a lot of information on his site. http://www.sounddeadenershowdown.com/ Hope that helps.

I used Dynamat Extreme in my car. Great stuff. I shopped around and found that I got the best deal on eBay. 36SF pack was $120 shipped but that was a few years ago.
Enjoy The Ride!

Thank you all very much...I think I have decided to go to with the Dynamat Extreme. Found it for $125 for the 36 sq ft. That was from the site I posted above.

For the last 9-10 years, Mercedes Benz has been using a 1/4" thick foam pad with cardboard on both sides of it (1/4" Foam, sandwiched between 2 layers of thin cardboard) as a sound deadener on the roof panels of their sedans. It is as light as a feather, and is commonly sold in the USA as Poster board. I've seen it sold in drug stores and art stores. It's never used in areas where it would get wet, such as a door, but would work well in a roof, or a 2 door 510's quarter panles, and it's a lot lighter than any stick-on tar like material. They glue it on with several 1/4" beads of windshield glue, but I think even a tough sealer that dries like rubber (not silicone) and has really good adhesion would work well too.

Check Fatmat on Ebay . 200SQ ft. for 150.00 , its enough to do a whole 510. I did mine, its pretty amazing stuff.
