Effective Foundation Insulation Approach (Lakes Region, NH)
I’m learning my way through the construction of a two-car garage with 740 sq. ft. of living space above. The foundation walls are done, but the slab has not yet been poured — that’s coming soon.
I’m looking for advice on the best approach to insulate the foundation. I haven’t settled on any one approach, but so far I’m leaning toward insulting the outside walls only, based on the information in this earlier post (https://www.greenbuildingadvisor.com/question/insulated-garage-insulate-below-slab) and based on this post as well (https://www.greenbuildingadvisor.com/article/getting-slab-edge-insulation-right).
