ThermaEZE is a technology that provides a cost-effective means for building thermally efficient above- and below-grade poured concrete walls. The insulation panels, which consist of expanded polystyrene foam, are set within the wall forms prior to pouring, and are held in place by a patented web structure that becomes embedded in the concrete. Once the concrete sets, the forms are removed, creating a wall surface that is fully insulated on the interior or exterior faces of the structure. The webs also provide a fastening surface for subsequent application of finish board and cladding materials. Hardly any prep work is required; the panels are simply slid into the cavity as the forms are set. Certainteed.
