Sound deadener?

[vette427sbc]

Anyone have any recommendations on a good sound deadener? Im not worried as much with the heat insulating characteristics as I am the sound.
I like Dynamat, but its way too heavy to do the entire interior in... lizard skin sound insulation looks like a contender. Any other brands? Bed liner?

I have heard good things about lizard skin but I do not have any personal experience with it. Eastwood sells something, too, that i have heard good things about.

I know this is heresy in some circles, but why not the stock sound deadener?

I bought this kit for my 1990 (not sure if they have C3 kits) anyways it came from a company called madvette or something like that. Foil over like plastic inflated air pockets sort of. Nice kit ... Down side a ACC massback carpet kit that is molded to the car likes original thickness sound deadening material or it won't lay down right.

think I paid like 105 for the kit.

I hate to tell you but that exact same appearing material is available at Lowes Depot for about 20 bux/roll, and it took about 1/2 a roll to do my vette, it lays down easy, all it took was some U knife work, I did mine in about a hour....

I used stock replacement padding when I did the interior on the 70BB. Works just fine if you crank up the music when you have the tops on. The stock replacement does not deaden the sound like you would experience in a modern vehicle.

I didn't have to cut anything, so worth the extra. More time to do other work needed on the car.

Since my corvette is a convertible and has sidepipes, I didn't bother with sound insulation, only Reflexit (Lowes) for the heat.
When I did the 72 442 I used Fatmat (ebay). You dont need to cover the entire panel to take a lot of the noise out, but I did anyway. Since this was my comfy cruiser I laid down adhesive fatmat, followed by reflexit glued to it. I put the tar paper life factory noise insulation over the reflexit followed by jute backed carpet. It's as quiet and comfy as a new caddy.

That isnt for sound insulation though, is it? Seems like most sound insulating products need to adhere to the body panels to reduce vibrations.

I think ill just deal with the added weight to do both sound and heat insulation from lizard skin... two 2 gallon buckets of paint should negate the couple lbs I just lost for $200 nicely :skeptic:

I feel EXACTLY the same re sound insulation...mines a convertible so the sound will easily travel through the top/windows/holes- why even bother? My BMW has double paned windows and about 700lbs of sound deadening from the factory- and you can hear every word my girlfriend says...in the Vette- I hope I won't hear a single word...

I'm am working put thin aluminum covering IN the engine compartment spaced a ¼inch or so from the firewall-and trans tunnel to keep heat OUT of the interior. My feeling is once the heats IN the cabin- the padding is just gonna STORE it...

IF you are driving it right, it won't be words, but screams of terror......:crylol::evil::hissyfit:

I insulated my 69 Z28 Camaro with some great stuff I got at HomeDepot
The insulation is like aluminum foil with fiber glass in the middle and on one side you peal off and it has adheasive on it.
The insulation was very easy to install and the price was great.
Works like a charm.
I plan on using it on my Vet as soon as I redo the interior.

OK, I'm a bit confused, wouldn't a sound deadener and a heat blocker be near identical? Maybe sound blocker would be denser whilst heat blocker would have more dead air?

Here in Vegas I'm thinking of heat block cuz it really comes up thru my bare floors.

 

[4 SPEED]

The stuff I bought at HomeDepot works for sound and heat.
It's the same stuff they use on duct work.
After you put it down and flatten it out it's probably no more than 1/8" thick.
My Camaro had a lot of HP generating interior heat and ground noise until I used this stuff.
Can really notice the difference now.

Generally sound deadener will have a lot of mass. Products like fatmat adhere to the metal will decrease resonance in the flat metal panels too. Reflective surfaces have some effect on temp. But generally thermal insulation will have little mass and prevent heat transfer from one side to the other. Think about fiberglass insulation in your house. Reflexit has the foil coating on both sides with an air space in between.
I used just the reflexit in the corvette footwells and made my feet very happy.
