I didn’t mention the cost of the foam. Even the salesman told me to brace myself before he gave the price. on fartbook there is always lots of discussion on whether to use it or not. But, of course we should always follow fb for adviseI’ve done the spray foam on a couple houses now and was never convinced that it was worth the additional cost. I went back to bat insulation on my current shop and am quite satisfied with how it turned out. I have Hardi-Plank siding with a membrane between it and the OSB sheathing, 2x4 studs with bat insulation and then 5/8” Sheetrock. The ceiling got R30 bat insulation rather than blown in just because it’s all decked in for storage.
I keep a large ceiling fan turning at all times and the interior stays pretty consistent. When I do decide to turn on the 2T heat pump, it adjusts the interior temp quite quickly and maintains it with ease. All in all I have no complaints with my choice and would do it this way again.
My total cost on the fiberglass was around $1600 where spray foam was pricing out around 15k.
