CCarpenter Posted March 30, 2021 Share Posted March 30, 2021 My foundation (see attached image) is a 4" slab on grade with a 1'-6" deep turned down stem wall. My sill plate is a PT 4x6 so I can get 3 1/2" of insulation to obtain the R requirement. The 3/4" subfloor will sit on top of this and would be the floor level with the finish floor allowance on top. I cannot figure out how to do this in the settings. If I set the slab at the top of the stem wall there is no way to make the subfloor which is 4 1/4" above it the floor. I want the sill plate sitting on the stem wall. I've tried making the slab 8 1/4" to account for the insulation and plywood subfloor then set it 4 1/4" above SWT but the program seems to not like that and increases the stem wall depth. I'm trying to adjust this in the defaults. Any suggestions? Link to comment Share on other sites More sharing options...
solver Posted March 30, 2021 Share Posted March 30, 2021 I'm not clear on your structure, but you may need an additional floor. Floor 1 has the slab and is 0" high, and Floor 0 the foundation below. Floor 2 is the raised floor with insulation, subfloor and finish floor. Link to comment Share on other sites More sharing options...
