Sound deadening and heat insulation

Cornpatch MO · Dec 1, 2014

I am trying to decide what to use on my 64 Dodge project. Most of what I have found is primarily for sound deadening-- not much said about heat insulation. I would think the inside roof and inside firewall would need the heat insulation. What you all using and how do you like it? Dynamat is expensive-is it really worth it? Best bang for the buck..........................MO

hi what I like to use is a insulation for the home it's @ 1/4" thick and it's foil faced bubble wrap. you can get a roll at Lowe's or Home Depot 48"x 25' for @ $43.00 it looks good and it works even at swap meets they are too expensive

Summit racing "B Logic", used it on my Charger. Great product at a great price.

Fatmat is 1/2 the price of Dynamat and works the same. Also I have seen people use lizzard skin recently and it looks great. As far as noise control i do not know but i was impressed how the Lizzard skin adhered and looked.

I tried looking that up on Summit Racing - I couldn't find it. Any additional details you can provide us to help us check it out?

Thanks,

Hawk

I used Fatmat.

I used a combonation of Fatmat and aircraft insulation

I recently used a product called Raamat BXT II. Its a rubber based product with aluminum layer as well. Its basically like dynamat but less expensive. Good stuff.

Thanks for all the input folks. I am thinking maybe some lower priced similar to Dyna-mat, adhered to the floor would be good sound deadening, topped off with a foil baked insulation from Lowes. I am a little leery about the bubble wrap stuff, but I have heard there is also a fiber filled -foil backed product. . Any more input is welcome...........................MO

First time around I used the insulation with aluminum on both sides of a layer of fiberglass. Wasn't too pleased with the sound deadening so I took it all out and went with Dynamat. Very easy to install and sticks like crazy. If you bang on a panel without it and then again after it's installed, the difference is night and day. Same thing with the door skins and quarters. I'm very happy with it. If you buy it in the box of 20 12" X 24" pieces, it's not too bad. Got mine from Summit; Free shipping.
A few pictures with the silver foil/fiberglass. The rest are the new black Dynamat.

Today, I saw on TV a resto shop that uses heat ducting insulation. They said it works much better than insulation for metal building walls. It is foil faced with peel and stick on the bottom side. I would prefer Lizzardskin, but pricey for my budget. I think I will use a product like fatmat or dynamat laid down first for sound deadening, and heat duct insulation on top of that
Thanks all for chiming in, and hopefully others will give their experience.................MO

Lots of choices. Doing the interior ceiling as you plan is critical.

I have heard Dynamat on the ceiling can get hot from the sun and pull itself off.
Has anybody else heard of that?

I sprayed lizzard skin inside and out when my car was stripped to the bone. It got EVERYWHERE. You can't get any kind of "peel and stick" type stuff where lizzard skin can get to , like even on top of the wheel cans, the engine compartment side of the firewall, etc. We had the car outside on the rotiss in 100 degree heat. You could really have fried an egg on the roof and could hold you hand as long as you wanted on the inside of the roof panel! i used both the heat and the sound deadening product, GREAT stuff. Be careful not to get it where you might not want it, like threaded posts or nut plates or you will be retapping them to clean it up. The nuts and bolts won't cut thru it.

Ran across this forum some time back, haven't done it myself but seems like a less expensive alternative to Lizard Skin. If you don't want to read the forum linked it's basically saying that you mix latex exterior house paint with cheap glass microspheres and end up with the same result.

Anyone tried it?

Went with the Fat Mat-Rattle Trap as well. Works great, easy to install.

Read a lot about this stuff on some other forums, but never tried it out:

Think i'll be giving it a shot on my current build.
