? about DYNAMAT

[Tom Welch]

Third Base, put it where you want to, it sticks, it stays. A useful site is E.A.R. specialty composites. Also Polymer Technologies Inc.

[USAZR1]

Useful if you're an accoustic engineer,I guess. Most of what I read on those sites went right over my head,Tom.

[Tom Welch]

I'm no engineer but these sites fairly represent the real deal in acoustical insulation and vibration damping info. The part I like best is that they offer a no BS approach to solving sound and vibration problems.

Was any more work done on this kit?

[Jagarang]

I'm at a critical point now as well, and need any help with this stuff that I can get! Tom?

I didn't read all this post but let me add that I used FatMat on my convert and it made alot of difference in the ride quality. The car feels and sounds "more solid". The doors sound better when closed. Easy installation, no smells, good stuff.

I didn't read through all the posts... so I'm sorry if it's a repeat answer...

Thermotec (the company that makes header wrap) has come out with acoustic mat that is much like Dynamat...without the expense of Dynamat. They sell it in all sizes, including a 30 foot roll for shop use.

Holy crap that was a long read. I'm getting close to needing somthing also. Tom how is the progress?

[69Rathead]

Have not read in this thread for awhile...thanks for the Thermo-tec post...I'm going to go with it as it is reasonably priced and looks to be comparable to Dynamat.

^^bump^^

anyone have any new input on the subject?

Seems like FatMat and LizardSkin have favorable experience here.

My buddy in the audio business just mentioned HushMat to me. It seems to have a large following as well. (at least for sound, not sure if they offer the heat-resistant stuff.

Gotta research them some more....

I'll be ready to buy something soon!

[blackwidow]

i seen somebody recommend this place www.rammaudio.com, price seems good. mike

[fladoans]

Yes I used Rammat also, both the sound deadening mat and the acostical foam. Give Rick at Rammat a call great people to work with the price is reasonable.

I bought Dynamat in bulk from Ebay and the cost was about 1/2 of what my local dealer was charging. The results are good. I installed two layers in the door panels. I imagine doing the floor would provide even great results.

The stereo sounds MUCH better and I don't have to crank the volume up all the way anymore for decent listening.

Check out the photos and some great links:

Well, I've read all that I can read, I've talked to everyone, and every company that I needed to and I've made a decision. (no small feat!)

I'll be buying Hushmat!! http://www.hushmat.com/index.html

A. I called Hushmat and Lizardskin people. I got much better answers, and more technical answers from Hushmat. Hushmat also has a large OEM customer base of Ford, GM, Chrysler, Toyota/Lexus and others. Lizardskin has no manufacturer or large corp. reference at all. (seemed odd)

B. Another selling point: Hushmat should have a much broader temperature range while still giving great results. Lizardskin or similar spray-on product doesn't have the same wide temperature range of flexibility/damping.

c. I can get a discount on Hushmat via a stereo installation shop!

D. Logically, at least in MY head, it's just seems like a 1/4" of flexible foamy/rubber/butyl thing would block more soundwaves and frequencies than would a 1/16" of a 'coating'. Soundwaves are just like that. (like a recording "sound room", home insulation, or a thick winter jacket)

Hope this isn't to late for some of you.....

I did a bunch of research on this and decided on FatMat's RattleTrap Extreme - it's not asphalt based and it's the thickest one I could find (and among the most affordable). 80 mil thick and $139 for 100 sq. ft.

[deak350]

I just installed 36 square feet of Dynamat Extreme from the bulk pak inside my Nova. I covered most of the firewall, trans tunnel, doors, and rear tubs. I can't say enough good things about this product. It is a night and day difference. This product is awesome. I am however going to buy another bulk pak and cover every single inch of the passenger compartment.

[Damn True]

How much does 36 feet of the stuff weigh?

[BA.]

The Dynamat Extreme is about .5lb per square foot.

There's some other product specs at this link, but note that the FatMat used here is the asphalt stuff.

Sorry for the stupid question, but what exactly are the benefits of using Dynamat/Fatmat?

Thanks,

It's used to help eliminate resonance sounds that are caused in the vehicle. For example take a thin panel and tap it with something metal and it makes a tinging noise. Cover the panel with some sound absorber material and try again. This time you should only hear a thump and not the high frequency sound.. Cars have alot of things that make sounds and moving metallic parts add to the noise level in the car.Sound competitors use it so when the music is playing there's no unwanted sound. If you have a certain frequency in you car and another freq or the same ineracts and cancels out both sounds. There playing against each other. There's been alot of research on all the freq in a car from the factories. The last one I saw was a brand new car had some 50 different sounds. Adding sound deadening material helps stop all those sounds. You notice I never used a trade name for sound deadening material. Dynamat has been at it the longest while there are several companies with less noticable names coming on strong. You can also try Hush Mat. I met with them at Year One and have been impressed with there products and not as much money. The new kid on the block can't be the highest. www.hushmat.com
