Hi, I am in the process of building a large garage in northern WI and will be installing in floor hydronic heat. I will have 2" on foam under the floor and 1" of foam as thermal break between the slab and the walls.

My question is... What is the best way to install the thermal break at each of the garage doors. The mason has poured the 4' frost wall and left roughly a 6" deep opening at each of the garage doors so that he can pouring the threashold at the same time as the floor is poured. I know I need a thermal break somewhere... Does anyone have a suggestion for the best energy efficient and yet asthetic and functional approach?

I know he is planning on a black expansion joint between the door threashold and the apron, but my guess is that this would still allow significant heat loss at each door apron...

I need your help and suggestions!!!

DJFlak;

I would continue the 1" foam thru the door opening and cap off with a PT wood cap for wearability
