My truck (82 D150) came to me with bare floors. It's hot and noisy, so I'd like to add some kind of sound deadener and insulating material to the floor, firewall, and rear cab wall. I will probably do inside the doors when I get time. I have vinyl flooring to add after laying down the sound and heat deadener. What kind of material have you used, and how well did it help after installation?
 
Killmat. The same as Dynomat but less expansive. Make sure to use the .80 mil.

Based on recommendations from various members I went with the 80 mil Kilmat in my 65 aagon. Just installing it made a noticeable difference in the sound level inside. When I finally get the interior installed, should be even better

would you guys recommend this kilmat under a headliner, stuck right to the roof?

i suppose it could be used on the roof as long as the roof was clean with no surface rust. My floors were clean with just paint so the mat stuck like glue. I needed to ajust a piece ir two after it had been down a couple of weeks and it was pretty tough to to move it and readjust.

I used stuff called Noico from Amazon. Was very similar to Dynamat except the foil was thinner. Also used aluminum furnace tape for sealing.
 
I heard that stuff is a nightmare to remove if you need to do a full restoration down the road. True? Short of a torch, how to you get it all off and down to bare metal?
 
Noico wont come off with a torch. I tried. Stuff doesent burn. It melts though. I used the noico without the foil, for the roof panel. Its been in the sun on 99 plus days, nothing let go. Made a difference for noise and heat.

I tried to pull some back after a couple weeks. No go, it really sticks after a few thermal cycles. I’m old enough that I figure down the road isn’t my problem…..

Yup. That's what I did. I didn't use any insulation. The Killmat insulates heat and sound.
 
Nothing...carpet with the jute padding. I don't want anything glued to my floors. And, who cares about noise when the top is down?
 
In my 65 Bcuda I used the 40? 50? Mil Killmat under new ACC carpet w/o the mass/moss backing. Seems to muffle ambient road noise, but once the /6 and single exhaust is up to temp on a sunny day I get the feeling that mastic gets warm and radiates the heat throughout the floorboard. I’m no fool- I know darn well its a dark blue car with black interior in CA, so theres that…

Is there a carpet supplier in the PNW that offers moss backing?

Dynamat Extreme on sale from Amazon with free shipping has always been my choice. It's a good start to insulating the interior, but unless you add a double foil sided insulating blanket type material too, you are only doing half the job. I use that wax paper sided foil ducting tape to seal the mat together and hold it down at the seams. I buy my mat from Speedway Motors or Aircraft Spruce.

My '70 E-Body sounds like you are sitting in a bank vault when you close the doors. I did both treatments under the entire interior of the car from the bottom of the front windshield to the rear window, door sill to door sill and under the headliner and door panels. The sound, heat and fumes were dramatically reduced inside the car.

Dynamat or equivalent used by itself is only half the job. It is really only good at stopping panel resonation, but not so much for heat and noise. The mat, properly installed, does the majority of the sound and heat and fume rejection.

I used the Noico, went in easy, Haven't drove car yet so don't know how effective it is.
