In eQUEST, when I select insulation under a slab for a basement, the Construction El1 UFLyrs(B.W1.U2) doesn't seem to recognize the default horizontal R-10 insulation; for 2 or 4 foot selections. In other words, the Construction layers do not change from an un-insulated slab in a basement......4 inch HW Concrete slab, 12 inch damp light soil, and a "dummy" value showing an R-Value of 100. Any tips or explanations are appreciated.
