Detailing an Insulated Slab for In-Floor Hydronic Heat
I live in Minnesota in climate zone 6. I’m building a two story with a slab on grade foundation (no basement). I plan on doing in-floor hydronic heat. I’ll have some bearing points coming down from upstairs, so I’ll need some interior foundation walls. Do I just not put insulation under the slab where the foundation wall is and pour the slab thicker there? How would you detail that? Should it be thermally broken from the rest of the slab? This is new territory for me, so any advice would be great!
