Low cost insulation job

I need to insulate an existing metal building. It currently has none. Any creative ideas?

What's the approximate cost of foam, cellulose or others per 100 sq ft ?

The building is just a workshop. Would like to limit solar radiation in the summer, and heat it to about 50 or so in the cold of winter.

How cold is winter?

How much do you want to spend?

Foil/bubble sheet may be sufficient. They do make insulation for metal buildings, but most is designed to be isntalled when the building is assembled, not after the fact.

If this were mine, in my climate (cold, New ENgland) I'd consider rigid foam with a foil face. Put that between the wall girts, and between the purlins on the roof. Rigid fiberglass would also work, but may be much harder to work with.

Obviously, to keep it low cost you'll be doing the work yourself.

You would have to check the prices in your area. I think you may want to check the price per cu. ft. Foam tends to cost more than cellulose, but the cellulose is harder to work with in walls. You may want to go with cellulsoe in the ceiling and foam or fiberglas batts in the walls.

Depending on how much you use the shop, the insulation could pay for itself in no time. Also depending on your climate and how good you insulate, you may not even need a heat source to maintain 50 deg. in the winter.

Oklahoma. Our mean temperature runs from about 35 in Jan, to 85 in July.

Actually, whatever it takes, including having a contractor spray in foam. But I'm thinking this would be the most expensive, and may be overkill for my needs. My top priority is roof heat in the summer, I don't plan to heating it in the winter time, unless perhaps just enough to keep it above freezing.

I'm not certain, but that's what I'm assuming.

I had wondered some type of foam panels. I guess my concerns here are fire resistance, what would make a fast and reliable adhesive for installing it, and how much could I save? I just didn't know if it was practical solution due to the need for just the right adhesive. The building skin is wavy corrugated "ag" type metal, meaning no flat areas to adhere to.

Probably so, I'm a highly skilled do-it-yourselfer with more time than money. But I will eventually hire a spray contractor if necessary. At least the roof needs some kind of attention before next summer.

I'm not sure how I could ahere fiberglass batts to the walls. It is not a stud wall construction.

That's very true. My main concern is the heat of summer. I might infact insulate only the roof, and let it freeze during the worst part of winter. It measures 30 x 80, so the cost of keeping it above freezing all winter might not be worth it. The contents do not demand it.
