My half doors have nothing in them except a huge reverberation chamber. I didn't even have the clear plastic moisture barrier, with super-duper goopey goo adhesive. So, while I was in there putting in my power door lock actuators, I decided to take care of that. $15 later and it's a lot better. I put pipe insulation in there, vertically, figuring that any moisture and/or dirt will still settle to the bottom and drain, like it should. I used a little less than 3 pieces of 6' long insulation designed for 1" pipe (a hair over 2" OD total), in each door. I just roughly measured, cut and wedged them in there, taking care to avoid the linkages. In fact, I didn't go all of the way up to the horizontal linkage rods between the door handle and the lock mechanism.
It's not perfect and I still get a lot of noise from the windows themselves but it is a noticeable difference. Maybe it will stay a little warmer too.
