The codes are silent about whether above grade slabs need to be insulated. Ground bearing floors shall be of adequate strength and durability and use concrete mixed and reinforced as necessary to support floor loads safely and resist chemical and frost action. Eps can be a cost effective alternative to pir for floor insulation and the same thermal performance can be achieved with increased thickness. These codes do not require any insulation for slabs that are more than 12 in.

Insulation below the slab suits continuous low level heating gradually warming the thermal mass of the concrete and sustaining it at a consistent temperature. These overall r values do not account for the heat sinking effect of concrete piers where they are included to support a slab footing from below. Kooltherm k3 floorboard is a super high performance fibre free rigid thermoset closed cell phenolic insulation for solid concrete ground based floors.
