Thanks for the input. I’m starting now with the double bubble. I know it’s not the best, but I do not like the look of spray foam. Funny fact, my Lowe’s had the 4x8 2” Kingspan panels marked at $7 a sheet, which they are $48 a sheet now lol. So I bought the whole store out
Hey guys, so I have a 30x30x10 shop. All the walls basically but the ceiling have 2” Kingspan foam board insulation. I’m sealing all my gaps now. Starting to insulate the ceiling. Btu calculator calls for 40k with poor insulation. Heater is a Mr heater big maxx 80k btu.
It’s not pointing to...
