How successful is using Dynamat?

[64wagon]

Damplifier pro I believe also has b stock that is also cheaper. You get it straight dryin secondskin. google it. It should be the first thing to pop up more than likely. I'm not sure on the others

i have my hatch front doors and front half of the roof done with dynamat, mad a huge difference. all with just a single layer. i did the front half of the healiner because the map light and roof were getting annoying along with the doors. helped keep done ratles upfront for better sound upfront. next is the rest of the trunk and then the rear doors and last half of roof.

I'll bet you really need the sound deadener for what I imagine are mostly dirt roads in Alaska. That's awesome that even one layer would make such a difference!

Any material that increases the mass without increasing the stiffness will be an effective sound deadener and the building construction ice dam membrane will do just that.

The ice dam membrane you get at lowes may not be as effective as Dynamat but two or three layers is. Considering you can purchase a 4' wide by 50' long roll of the ice dam material for the same cost as a 18" by 32" sheet of Dynamat it is a much less costly way to go.

I have had two layers of the ice dam membrane covering the entire floor of my 68 Barracuda for over 10 years now. It works great and the heat from the headers right under the floor has not impacted it.

FWIW, most of the purpose made products are asphalt based too.

I'm using some stuff called Fatmat and I got it from http://www.fatmat.com/

Dynamat is way, way over-priced unless you get dealer cost for it. Butyl rubber is not asphalt based.

[Dgc333]

Butyl rubber by it self is not as dense as Dynamat meaning it has something else in the make-up. When I was researching sound deadener for my Barracuda I read a number of comparison articles and saw a number of references that these materials used asphalt to give them the density. These articles also said that the ice dam membrane was very effective.

In any case Dynamat if not the most expensive it is close, even the cheapest stuff is still about 3x or more, more expensive than the ice dam membrane material.

A actual deadener with the foil constraining layer deadens in a different manor than mass loading a panel to change its resonating frequency ...

most of the roads are paved, lmao.
