sound deadening mat or insulation inside doors

[spacedebris]

I've not used it but in my research for a sound deadening / heat shield product I ran across one that claims to prevent condensation and does not hold moisture.

Its called EZ Cool Automotive Insulation.

sounds good on paper but I have no experience with it.

For doors you want a butyl peel & stick type sound deadener like Dynamat, Second Skin Damplifer, etc. They have a layer of butyl rubber and a layer of aluminum and if installed right will not be able to trap moisture. The butyl damps vibration of the panel reducing noise transfer, and the aluminum provides both protection for the butyl and some heat transfer protection.

I've used damplifier on a few vehicles now and always been happy with it. A 1' x 1' square in the middle of the outer door panel with reduce the 'tinny' sound of doors by an impressive degree, more will end up with them sounding like bank vault doors. My plans for the truck once the door rust is fixed is a 1'x1' square on the lower outer skin and a small piece on the upper inner skin by the door handle, then cover the entire inside of the removal inner panel(and possible one piece on the lower inner door panel depending on access).

Here are some pics from other vehicles:

(the grey stuff is a plastic based carpet padding from lowes that won't rot if it gets damp like jute will)


And here is the damplifier installed in the cab of my truck(the newer version of it is black instead of shiny). Sadly I'm now replacing the cab so I'll have to do this all over again.
