Good sound deadening material

Hello all. What, in your opinions, is the best sound-deadening material to use on our cars? Of course, it would be fire -resistive material and lightweight. And hopefully, not too expensive.

What do you-all use?
 
I just replaced all the original sound deadening material in my TR7 with Dynamat Original. It took 1 1/2 of the large rolls and cost $80. You can pick it up from any car audio shop.
 
I just read on the Classic Motorsports website in the projects updates that they used a roofing material in the Volvo 142. It comes in rolls about and is a rubbery/asphalt materal that has adhesive on one side. You can get it at Lowes, Menards, etc., but don't take my word for it:

They claim it does a great job at 1/4 the cost of dynamat.

Dynamat is great and $80.00 isn't that much, but as always, expensive is a relative thing.
 
Check with anyone that builds metal buildings, there is a foil covered type bubble wrap that they use for insulation, it is light and inexpensive, I do not think I would use on firewall but other places ok. I used in my GT6 it is easy to work with when covering anything
 
I wish I had known about that stuff before I bought the Dynamat! Oh well, at least I'll know the next time I do something like this.

I haven't rechecked with the article on the Volvo, but I wouldn't bet that an asphaltic roofing material would be fire resistant. I have read of people finding a Dynamat like material for a lot less money, just don't recall where. If you go back trhough archives, you may find a reference.
 
The stuff is called ICE AND WATERSHIELD. It is self adhering and used under roofing shingles along the eave line and in valleys. About $50 for a 3' x 33' roll. Keep an eye out for a roof job, If the foreman isn't around you can barter an ice cold 6-pac for a few feet of it.
 
I would not use any roofing material. You will never get the tar smell out of the car, probably has toxins. The dynomat seems the great way to go, looks original also.
 
Lots of goof suggestions. Here's another one:

VB2

I have used this stuff and been very impressed with its low weight, high dampening properties and ease of use. Its similar to dynamate, but in my humble opinion is better and easier to apply. The downside: It ain't cheap.

Thanks for all the great suggestions. I was looking for an alternative to what I now use, the aluminum bubble sandwich stuff (two layers of aluminium with plastic bubble material in the middle) from Lowe's that's intended for wrapping heat & A/C ducts. It's heat resistant up to 350F and easy to manipulate. Best of all, it's inexpensive at about $25 for a huge roll, more than enough to do my entire car.

It's currently on my firewall, gearbox tunnel cover and floor pans. After these suggestions, I'm putting it everywhere.

Thanks again for the input, everyone!

The VBlok I recommended is more of a sound shield that a heat shield, although it does help reduce transfer of heat, its probably not as good as some of the other products mentioned.
 
If you want sound deadening, get dynamat or the roofing stuff Per found for the Volvo. He's a smart guy... if he says it works, it works.

If you want heat shielding, then go back to lowes/home depot, and look for water heater insulation... shiny foil backed with about a half-inch of a sort of shredded felt stuff. Extremely good insulator, and of course, given it's intended use, has good heat/flame resistance.
