Poll for door insulation placement

[uao85]

Wondering what you guys think I should do with the dynamat on the doors. I have them stripped down ready to paint, so should I

A) Put the dynamat on the inside of the door shell on the inside of the outer door skin

or

B) Put the dynamat on the outside of the inner door skin underneath where the door panels mount?

If either one, please give some reasons why.

I always see the hot rodders putting it on the interior outer door skin.

I put mine on the outside of the interior door panel (underneath the cover). That way all the rattling from the window mechanism, door locks, and other noise makers would be blocked. It works very well.

good point. The reason why I am doing it is to drastically reduce road noise, as well as any other type of noise from the outside of the truck.

I put mine on the backside of the interior door shell, mainly to stop rattling of the door latch and window crank, worked great!

As long as the stuff is between your ear and the road, it'll reduce road noise.

the interior of the door can act like a giant reverberation chamber thats why damping the outer skin can be better at keeping the drone type noises out.

think of it like an empty oil barrel, if you line the sides it will keep sound from bouncing around. <- door skin. If you just line the lid all the noises bounding about off the interior walls will find their way out <- door panel

if you really want to cut the noise back, dynomat the door skin and put a layer of felt padding behing the door panel.

it's cheaper than dynomat and would be held in place by the screws and trim snaps of the panel.

I say do both, overkill in this situation is better then not enough, especially when your door is like a beer can.

I agree

I used dynomat extreme on the inside of the outer panel and the outside of the inner panel. I got it at a great price and wanted the best noise reduction. I also did the bottom of the roof and also have a head liner. It definitely helped, but the door that is not done, the floor, and the back of the cab are also on my list to do.

that sounds exactly like what I am currently doing to the cab of my pickup. Only I am afraid that doing the doors twice for both inside and outside, will take up alot of the material I bought. I got the largest kit they had, which is 36 sqft, so I guess I will just have to see how far it goes and if need be, order a few more sheets.

I am currently doing a project to do just that. I am putting raamat on the inside and outside skin, under the headliner and the entire floor. Then I am putting a layer of ensolyte foam over everything. Oh and also sound deadning under the rear quarter panels. The only issue that I have is how to do anything to the noisiest part and thats the fiberglass shell.

Some of the hot rodders and stereo guys are using this stuff, its much less expensive and available at Lowes and HD

I am going to have to check this one out if I need any extra material anywhere. I knew I had seen this sometime in the past, but didnt know where it was sold, or what its original use was for. Now I know, thanks.

Both... overkill good.
