Insulating a metal shop?

HankRearden said

I have a buddy that insulated his steel garage and I will be insulating mine the exact sane way.
He cut rigged foam to fit between the studs and trusses. Then he used a case of great stuff spray foam and glued the rigid foam the inside of the steel siding.

This is the most cost effective solution we could come up with.

I think I'm going to go the same route except I'm going to mount some furring strips on the metal studs and then attach a flat simpson strong tie plate across it to hold the foam in. This way the foam will be even with the furring strip and that'll allow me to cover it with whatever I want in the future. Otherwise the foam will stick out further than the stud.
