2nd Gen Non-Engine/Transmission Door panel noise reduction?

[Clinton]

Noise reducers and sound proofers I have a question for you. I did pretty much the rest of the cab last year and thought I'd finish the job by doing the doors. I'm using GSI 1/2" Soundstop and wondering about where to glue it on the door. If I glue it to the inside of the outer sheet steel won't water run on and through the foam? That's where I'd like to put it, but I'm not sure that it'll stay glued there or that I like the idea of the foam possibly holding moisture against the panel. I've got the door panels off and I can reach the entire area inside there, but I don't want to waste time and have to re-do the whole thing later. Also, for coverage sake you can get a lot more coverage on the inside of the outer steel than you could by gluing to the inner steel under the door panel (i. e. more noise reduction). What do you think? Thanks.

I glued mine to the plastic door panels. I also did 2 layers of dynamat type stuff on the metal and the difference is great

Dynamat Extreem Inside all 4 of my doors mad a huge difference. Especially in terms of the audio enhancement. I did the back wall as well. Killed the drone thats for sure.

Clinton,

I have done what you are proposing, I used 1" GSI soundstop on the door skin inner surface. I used Weldwood contact adhesive to bond the soundstop to the door skin inner. A couple of hints are to: Make a template out of paper or cardboard first. Cut the foam to the template and trial fit it. For the most sound reduction, you want the foam to cover the door inner skin completely. Once you are happy with the fit, then apply the adhesive to the foam and the sheet metal. Attach the foam to the skin while the adhesive is still a little wet, this will allow you to slide the foam into position. To minimize any water problems, I applied foil tape to the top edge of the foam after the install. I used the Weldwood to adhere foil tape to the door skin and to the foam top edge and to the foil backing of the GSI foam. Any water that gets past the window seal will move down the foil tape, and down the foil backing of the foam. Hopefully not saturating the foam.

I also applied Dyna-mat type material to the door inner structure, and I also glued insulating foam to the inside surface of the door inner trim panel.

I did the same to the rear doors of my quad cab.

The difference in sound / noise coming into the cab is significant. It is most noticable when driving next to a wall or next to a semi.

I have done this level of sound reduction all over the inside of the cab, and under the hood. Most will think this is way overkill. My wife and I really enjoy the quiet ride, it is especially appreciated at the end of a long day on the road. We arrive at our destinations a lot less fatigued. For us, it has been worth the effort.

Maybe Greg the noise Nazi (the patron saint of noise reduction in the 2nd gen. trucks) will chime in and share some insight?

great post Geoff! I forgot to mention that I Cleaned the inside of my doors themselves with 91% alcohol and while that was happening I had my pre cut pieces layin on the Hot Summer fried blacktop (or in the bed is good too) then applied it to the doorskins. Even after that I hit it with the heat gun for ultimate transfer. My doors close with a resounding THUD wheras before you can hear the door workings giggle.
