To insulate or not to insulate?

Bill,

If there is a source of heat, cold or moisture in any building, then it will sweat. Even highly insulated top dollar homes will sweat, just look at the windows.

My statement is based on sheds and barns without heating or cooling systems.

I dont' think the second layer of roof eliminated the humidity four guys are creating in a small cabin, but instead your allowing it to disipatate into a new area and it is now less noticable.

My shop is 40X50 with slab and I just have the roof insulated and during the winter I have had a few nights where I wished I would have insulated the walls. But no sweating problem.

The building doesn't sweat. It's the stuff inside that does. I had a car in an enclosed trailer. We had a false spring last year and the motor in the car rusted up pretty bad. What happened is the days were fairly warm and the nights got fairly cold. The uninsulated trailer got full of warm moist air in the day and the cold nights condensed the moisture out of the air onto the the big iron that didn't heat up during the day--the engine block. It was a done car, now I have to re-do the motor. Sheet metal didn't get hurt.
