Thread: Sound Deadener

Tweet

Dyanamat and Hush Mat are a bit too proud of their product for me. I know I've seen an alternative here, but my searches don't find it. Anyone have more reasonably priced alternatives?

I bought a lot of the fancy insulation for my 33 and I didnt think it was worth it. This time I want to try lizardskin on my 32.

Check these guys out..............

Take a trip to Home Depot's insulation and roofing aisles. You'd be surpised what they have these days, I saw a foil covered fiberglas/bubble wrap stuff that looked promising.

One of my father's buddies ordered a precut sound dampner/insulation mat kit for his car and what arrived was just template cut peices of Grace water and ice shield, a common roofing product.

I'm looking for that stuff too. Thanks for the links.

I kinda like the second skin damplifier pro based on price and thermal performance for Texas use ..............

Jack which way are you leaning? There are of course the real cheap aluminized fiberglass products. Having it stick to the sides of the roadster at temps approaching 140F in the direct sun is paramount for me.

Kitz,

The RAAMmat with an Ensolite overlay in the cabin was kind of interesting - but apparently they're out of stock.

Right now, I think the Damplifier Pro is the way to go. That should give me a heat and sound barrier, then the carpet an matting will add more sound deadening. I need that in the cabin, because the two big Flowmasters, cross-over pipe and 2-1/2" tubing run right underneath. Also, with a channelled car, I'm sitting pretty low.

Then again, I kind of like the look of these. Maybe I'll change out and get rid of all the under-car heat. It will move some of the noise outside also.

...VERY interesting articles! I'm about ready to pull the trigger on insulation for my '32 & was going to get Dynamat BUT after reading these sites I think I'll go with Second Skin Audio.... A LOT less money & a better product! I had over $500 dollars worth of Dyanmat in the doors alone of my Firebird & that's WAY to much to spend! THANKS, Bill

How about the stuff under the Diesel truck hoods? Would that stuff work? It cuts the diesel noise down pretty good.

It's all marketing, shop wisely...

Great info articles , Bringing early reading for me but hope to be at this stage by late fall .

Well, I just received 80 SF of Damplifier Pro. It looks like good stuff, but you'd think for $300.00 they could have supplied some directions. None in the box, none on the website (that I could find).

Be carefull with any of the foil backed "peel and stick" stuff that you can buy at Home Depo or any other hardware store. When I built the roadster pickup, I tried to save a few dollars, and used the home Depo stuff in the doors. I followed all the instructions, cleaned the inside of the doors carefully before the application, and used a roller to make sure that the "insulation" was carefully pressed into place. After a week of setting out in the sunlight, I had a great big ugly wad of this stuff in the bottom of the doors, and nowhere else. Then I had to dig it all out, and start over again with Dynamat---and have had no problems since.---Brian

I was on a budget, so for the time being, I used the Home depot stuff that is made up of a small bubble wrap, covered in fiberglass, then encapsulated in foil... It works great and is extremely inexpensive.

Denny,

Yep, that's the stuff. I've put in 7 or 8 sheets already, and no cuts. I can't wear gloves because it's too difficult to handle the stuff. However, I don't smooth it into place with my hands. I use a bondo spreader and a roller. I bought some aluminum foil HVAC tape and am using that over all the seams. These pictures don't show it very well since I was using a flash.

Brian,

This is butyl based, not asphalt-based stickum. I think it will bond just fine. I researched a bunch of different products and decided to stay away from the big-box store roofing materials.
