Basic Material List
I asked Bing AI to take the Basic Materials List and get the current prices from Lowes.com — It didn’t do a perfect job, but it wasn’t too bad.

XPS comes in 2”, 1.5”, and 1” thick pieces. The thickness you get depends on the width of your joists. If you have 2×6 or 2×8 joists, then using 2” panels and layering them is ideal. Each XPS 2” panel is R10, so if you have three, then you have a value of R30, which is excellent.
