Radiant Heat in Slab -- HELP!
Is not-insulating the slab a fatal flaw? Is it the reason for the poor
heat-up? Will it cost a lot more to heat without it? He seemed to think it's
a nice to have but not a have to have.
I need to know if failing to insulate a slab above which will be a floor
with radiant heat is a negligent act.
