Insulation over slab

Don Regan

2.5"? we use the 1" Crete-Heat with a 1.5 " light weight over pour. This gives you the thermo break you need or you end up heating the slab below.

I am about to finish my basement with an existing concrete slab. I will be installing electric radiant heating over top of this and am hoping to get some input on what products to use for insulation/thermal break. Styrofoam will be too thick Any help would be appreciated

Cast Iron Baseboard Radaitors.. Pricey, but can't beats the comfort when installed properly..
