morton building

On the ceiling I would look as sprayed foam. One problem when heat is added in metal building is condensation on metal roof underside in area. IT RAINS in there after a while.

We have tin (?) siding on the inside of dads shop with blown in insulation in the walls and the ceiling. We have never had an issue with it raining on the inside. We keep it about 40 at night and warm it up to about 50-52 in the day time.

Whatever you do, don't use fiberglass or blown-in insulation that is going to provide rodents with a lifetime supply of bedding material.  I have a detached frame garage that a previous owner insulated half of with sheet rock walls and ceiling and fiberglass.  The fiberglass ablove the ceiling is absolutely full of rodent droppings/urine and acorn/hickory nut hulls.

I was actually cautioned as to not finishing out the inside of a truss construction pole barn as the roof truss load was not designed for internal loading.  These are not house designed trusses and they are not on 2' centers with center support walls in contrast to home construction.  I am looking to build a barn on our new place within a year or so, it will need to be designed with living spaces in mind to do just this same idea. 

Another of my cronies built a 'Game Room' pole barn but he has found why it wasn't a good idea; the roof does not seal well to the wall panels, it let moisture in large quantity to the inside, that in turn kept the insulation wetted over the last five years with this not only developed mold and damaged the drywall he put in but has started rusting out the wainscot panels around the base of the building.  He is in the process of tearing down the whole structure to the framing and roofing to start over as it is a mess.

One of the best ideas I've seen is to install horizontal "bookshellves" between the poles and use whatever insulation you choose between them.  The inside edge of the "shelves" then serve as nailers for whatever interior finish (sheet metal, drywall, paneling, etc) you wish to use.

Shameless, whats up with the rain once.

a friend of mine put that pink board in between the inside nailers on the outside walls, he then stapled plastic over that, then nailed nailers on the inside posts, nailed tin on the inside nailers up so far, about 6 ft, then used that blow in insulation behind the tin. he then went up the next 5-7 foot and did the same thing. reason for the 2-part job, was so the blow in stuff wouldn't get bridged up leaving a void in the wall. that was about a 60x80 building. heated the whole thing with one of those double barrel wood stoves, in the dead of winter like zero degrees and below outside, it was t-shirt weather inside!

I was warned of the same thing when they put up mine some years ago. Second day it rained inside, then quit and hasn't done it again. I was told it was due to the mositure wicking out of the concrete as it cured.
