I almost put this in my ongoing thread in the owners section, but figured it would get more eyeballs here than 4 pages deep in a thread up there.
About to be building a metal building on commercial land. 40x60x14'. 2 12x12 doors, 2 man doors. Gulf coast, so AC is the consideration, heat is not a concern.
My initial thought is that I want the building spray foamed. I've worked in a couple spray foamed buildings (in a cold environment, though), and it sure seems like the cats meow. However, those were all old buildings, decades out of warranty. I'm finding that when building new, spray foam voids the sheet metal warranty, though the building salesman say that many folks do it anyway.
I'm trying to avoid the vinyl coated fiberglass rolls pinched between purlins and sheet metal. My current shop has them, not impressed. What are my other options? 2" thick foam board, cut and fitted into the walls and ceiling? 1" thick foam board with a 1" layer of spray foam over top (to better air seal gaps)? Is there some material that can be rolled out on top of the purlins under the sheeting that can have foam sprayed onto it? Or, just spray foam the thing, warranty be damned?
Yes, this is a question I should be asking the building companies, but I seem to have to hold their hands on anything that's not standard fiberglass batting.
I haven't been able to get much info on insulated exterior sheet panels, but I'm not sure they are going to be in the budget. The companies that seem to be more apt to offer them aren't interested in building such a small building.
And yes, I do plan on having insulated roll up doors, which seems to trigger an error message in the mind of a building salesman. Salesman for one company went on and on about how expensive these doors are when we discussed plans over the phone.
Another company doesn't offer said doors, but would happily build the building with just door openings, I get doors elsewhere. Called Overhead door company - he's going to email me a quote, but wanted to warn me ahead of time that these are going to be very pricey. Apparently, no one ever buys insulated doors.
