Where insulation is positioned above the slab.

Ground floor slab insulation details. Ground floor insulation below concrete slab thermal insulation is usually installed below the floor slab in buildings featuring continuous low level heating. Eps can be a cost effective alternative to pir for floor insulation and the same thermal performance can be achieved with increased thickness. The codes are silent about whether above grade slabs need to be insulated. It helps make effective use of the thermal mass of the concrete slab rather than repeatedly warming it and allowing it to cool.

These codes do not require any insulation for slabs that are more than 12 in. 4 10 2012 5 floor surfaces less than 12 inches below grade shall be insulated. Alternative solutions 4 and 5 for continuous insulation of on ground concrete floor slabs.
