What Kind of Insulation Should Be Put Under a Concrete Slab in a Garage?
Generally, installing insulation under a concrete slab in a garage is not incorporated into the building of a new home. Usually, a homeowner does not think about insulation under the garage floor until the cold of the winter. At that point, it is impractical to insulate under the existing slab without tearing up the existing floor or installing an insulate floor on top of the slab. It is best to plan for and install insulation under the concrete slab from the start.
