Block Stem Wall Slab W/ Limited Insulation Tapered Slab
Hi Guys, I’m in the process of finalizing a plan for a Stem Wall Slab foundation. I’m in CZ4 and nearly all the Stem Walls here are CMU and not poured.
I wanted to insulate the slab in some fashion and have attached images of two ideas and wanted to get your advice.
One is with 2×6 framing, a tapered slab, with a 6″ top course and insulated down to the inside footing as the attached image shows. The other is 2×6 framing with a 4″ top course. The insulation for that plan runs horizontally under the slab 24″ in a picture frame format.
I would like the keep the 6″ top course plan but am unsure of the tapered slab idea. What are your thoughts and suggestions? Thanks, Todd
