Should You Put Rigid Insulation Under Concrete Slab?

Depending on where you live, rigid insulation under a concrete slab might be required! The IECC, a regulatory code that ensures new construction is environmentally conscious, requires a minimum of R-10 insulation in Climate Zones 4-8. You can check if you live in one of these zones on the IECC zone map.. If the IECC requires rigid insulation under concrete slab, you’ll also need to get an ...

Polyethylene Under Concrete Slabs - GreenBuildingAdvisor

04-07-2014  Because concrete is an extremely effective vapour barrier, we aren't concerned about vapour from the house condensing on the "cold side" of our insulation against the poly and building up there below the foam (which is why one would normally place poly on the warm side of their insulation a-la walls and roof).

What kind of foam do you use under concrete slab?

30-06-2020  Designers generally insulate both directly under the slab and around the perimeter as well. In cold climates it is advisable to use a minimum of 2 inches of extruded polystyrene under the slab. Many increase the under-slab insulating foam board thickness to 3 or 4 inches at the outer 2 to 4 feet of the slab.
