No gap to insulation (convective loops), fire-blocking required every 10' horizontally, no poly on concrete unless an interior drain system (water will drain down, pool at frame wall plate, depends on location), no empty cavities (conv. loops), use foamboard thick enough per location (varies- to prevent condensation), foamboard (better than poly/sill sealer for thermal break)under bottom plate, poly or other, between studs/concrete wall (p.t. not required per code here), air-tight drywall (keep interior air from concrete), and no poly under drywall ( U.S. code dropped this due to mold- keeps cavity wet, though in very cold locations may work).
