The cold will come right through those ribs and cool down the inner steel skin unless you create a thermal break between the rib and the inner skin. How much time you want to spend on insulating will probably depend on where you'll be traveling and the time of year.
Wow.. missed your post somehow. Thank you for the explanation, yes the R-11 said 3" on it. I can see where people are leary of even rivet heads transferring cold. We have been having an unusually cold winter month this year but usually it's not that bad. Now people have me worried about the heat.

A 9/64th drill bit is perfect for sheet rock screws going into metal.

Thank you. Was going to buy one tomorrow. had one that was working until it broke.. think it was for wood. I was drilling out the aluminum heads on the rivets, some were steel I think.

We did not remove any of the interior sheet metal. We had NO rust at all in our bus. When we pulled and recaulked the windows, no rust. No rust in the floor, no rust under the floor. No rust in the doors. We had a little surface rust in the entry steps. A little surface rust at the bottom of the entry door. We removed the metal pieces directly above the windows where the wiring runs. Fiberglass insulation was in great shape (except for the two pieces that someone had removed and apparently tore up). No rust. And we even had a small leak in the ceiling. No rust though. We dealt with rust in our Eagle. We were looking for rust. My hearing is very good. I beat on all the walls listening for the sound of falling rust. Besides we have about a ton of rivets. No way we were going to deal with all those rivets just to remove insulation and then add different insulation. I firmly believe BlueBird pays their workers based on how many rivets they use. Rivets are all in good shape. BlueBird makes a well put together bus.

Rivets transfer heat as well. Here in NM, I had a rivet get hot enough during the summer that it blistered the bottom of my foot that I had propped up on the side wall. I have... "prop-itis". I prop on everything and laying on the bed with my feet propped up on the side wall while I read a book is very comfortable. Rivets can get very hot.

Thermal breaks and insulation are very very important. For both hot and cold.

Re: Transmogrifie and Me

I noticed some busses do have a lot of rivets. The panel I took off had maybe 15. Even my ceiling panels have one every 2 feet or so. Not as many as a lot of them I'm seeing. I just thought you meant that you put some sort of sealant behind the metal somehow.

I didn't want to cut corners but I can see the need to not tear off all of the interior sheeting at this point. Timing.

It was 1/4 inch luaun it said on the shelf, I dunno. Sometimes I get a guy at Home Depot that doesn't know anymore than I do it seems. I decided to go with half inch plywood on the floor. More expensive but I need the stability for the Allure Trafficmaster and the carpet guy thought it best as well for 1/2 inch. Course.. haven't bought it yet either.

Re: Transmogrifie and Me

I've been seeing some crappy looking Luan lately. It still looks like Luan basically, but it has a lot of imperfections like cheap quality plywood. I didn't think there was more than one grade of Luan. What the hell is going on? Seems like the quality of wood is getting worse every year!

The rivets on our bus are the same inside and out. One Rivet holds on the exterior AND interior skins. The vertical rivets on our bus are spaced 1-1/2" apart on center and horizontal rivets are 3-1/2" on center. No way we were going to drill out all those rivets. We would still be working on the rivets. I tried to count rivets one day but lost count.

On a ceiling panel: there are 55 rivets on each of the 8 seams. Then there are 7 more rivets between seams (7x7). So the ceiling alone has a total of 489.
