Insulation for office in a metal building
I’m ready to build an 8 x 20′ living quarters in my 30 x 50 metal shed (not insulated) in Southwest Virginia. The living quarters will use a mini-split for heating and cooling. I plan to live in it while I build my house. The price difference between doing a general build using 2×4 regular insulation versus a 2×6 Rockwool insulated is about $1200. My future plan is to use this as an office.
Will the thicker walls be a good return on investment, or is that overkill?
Thanks,
Charlie

I’m not a builder and haven’t worked in the trades for decades, here’s my 2 cents…We have just had a 40 x 50 pole barn for the tractor, etc. put up with a dog bath room down here in the Western Piedmont of NC. Dog bath isn’t done but the walls are up, I’m insulating the room with rock wool. We are using a space heater for winter when needed as they tend to like to find skunks in Winter and early Spring. The building is insulated, though this Summer it’s been really hot in it even with both big doors open for the breeze. It took months for the building to go up starting last year and the Electrician will be hanging lights on Monday. Seems weather and materials being on back order has delayed the project a lot, not to mention the Electrician and Grader being extremely busy. I think our Grader is overbooking and having difficulty getting back to us. He’ll get it worked out, I have faith in him, just young and a new business.
Here’s my thoughts on yours - I’d go with the rock wool. I had some left over from a project and we used it when we had to have our master bath and closet remodeled before we could move in. The master bath is the coolest room in the house during the Summer. It has the least amount of shade, farthest from the HVAC system and shares a wall with the garage. It was the warmest room before the rock wool went in, especially when the sun hit it in the afternoon. Since you don’t know how many delays will occur during the home build, being prepared is never a bad thing.
I’m in Oklahoma. There’s a massive amount of metal buildings here they all use close cell foam.
Wood structures use open cell foam
