How does under slab insulation reduce moisture movement from the ground?
Under slab or under concrete insulation are composed of low permeation materials and therefore resist moisture. Because our under slab insulation for concrete floors will resist moisture, the room in which the floor insulation is installed will be comfortably dry. This is why INSTA-PANELS® are great in garages, basements, and lived-in areas. Please note, it is best practice to ensure the area under the slab can drain and move moisture away from the insulation and concrete slab.
