We are in the middle of the design stage with the pole barn company in building a 40x40x14.4 with a 16x48x16 gable end RV garage attached. I am planning to insulate the slab in the 40x40 section so that I could do a radiant heat floor at some point. I plan to have a lined ceiling and going to get double bubble walls and roof right now, will finish the walls with OSB and batt insulation later on my own when I can save up some more pennies.
I'm in NJ
What are peoples opinions on doing the 2" rigid foamboard and pex tubing before pouring the 5" slab versus just doing gas fired heating blower. I plan to pull natural gas into the pole barn in a separate trench when I do the electric at the same time. I am not looking to be 70 degrees, but more like 40-50 degrees. Melt the snow off vehicles and not freeze things during the winter.
