Insulation for concrete floor slabs.

Insulating a concrete floor can save you money on your heating bill making an attached garage or basement warmer and by extension the rest of your house. Where the heating is likely to be turned on and off such as in new build domestic properties and a faster thermal response is required the floating floor arrangement of.

Otherwise both codes require that slab on grade floors with a floor surface less than 12 in.

These codes do not require any insulation for slabs that are more than 12 in. The foil within the product acts to spread out the heat signature of the heating coils. Such spaces typically have a sound level concrete slab floor but lack sufficient floor insulation to achieve the thermal performance targets for. Insulation below the slab suits continuous low level heating gradually warming the thermal mass of the concrete and sustaining it at a consistent temperature.

Check out this article for a list of slab edge insulation solutions and episode 125 for my interview with henry edney of maxraft. The codes are silent about whether above grade slabs need to be insulated.
