R stands for resistance an R-value is a measure of how well insulation resists heat flow. It is generally accepted that an off the peg pod floor offers minimal improvement in thermal insulation. The R-value of the installed insulation. Underfloor insulation needs a minimum R-value of 13. Total R-value R-value means the thermal resistance m2KW of a material calculated by dividing the thickness by its thermal conductivity. A reasonable R-value for a normal concrete slab can be estimated using an R-value the thermal resistance per inch of thickness between 01 and 02 and multiplying it times the slab thickness.
H1AS1 amends NZS 4218 so that concrete slab-on-ground floors are deemed to achieve a construction R-value of R13 unless a higher value is justified by calculation or testing.

The R-value of the floor structure and floor insulation. Typically it consists of an 85mm thick slab supported by a grid of ribs normally 100mm wide at 1200mm x 1200mm centres. When the required R-value exceeds R13 the case with slabs that have embedded heating systems the construction R-value must be established by calculation or physical testing. A reasonable R-value for a normal concrete slab can be estimated using an R-value the thermal resistance per inch of thickness between 01 and 02 and multiplying it times the slab thickness.
