I just had a new pole barn put up and had a couple of questions;
I am using fiberglass batting as the insulation

I am using cans of sprayfoam along the top and bottom of the wall to fill in the gaps from the ribbed steel, will this be enough or should I use the foam at every horizontal stud to fill the space at the ribs?

Once I get my walls done, what will I need to know before starting the insulation on the roof.
