Insulation under a slab

I am in the process of building a pole barn and I'm wondering if putting insulation under the cement slab would be worth it/cost effective. I really want an in slab hydronic system, but right now it's not in the cards. I live in SE Michigan and the slabs are always so cold and take so long to heat up. Thanks.

Re:Insulation under a slab

unfortunatley you cant

BUT you can insulate the exterior walls of the foundation

using 1 1/2 to 2 inch " pink board " ( field name ) or any polystyrene with a 5.0 R factor per inch

then back fill your foundation

use a " Z" cap made from aluminum to cover the exposed board to protect it from UV deterioration and your weed whacker

" Z " caps can be formed with a siding brake to exact and custom specs.

Some may say you can insulate under the slab but what are you going to use the building for ? you parking cars ? semi trucks ?

It all falls down to what you or future owners are going to use the structure for

hope this helps
