By the next morning the radiant heat was running and the crew was already laying finish flooring. In twenty-two years of building, I've never seen a subfloor cut install time that dramatically. The slab is warm under bare feet by the time we sit down to dinner.

February in Stowe. The cabin sat unheated for three weeks, then we came up, hit one button on the thermostat, and the floor was comfortable by the time the car was unpacked. No boiler cycling, no cold-stone shock — just warm wood.

Heating an ADU over an unconditioned garage has always been a fight. The ThermaSlab panel solved it in one step — and our slab-on-grade heating bill is actually lower than the old baseboard setup. The whole loft is one warm surface.
