The ThermaEZE™ Thermal Insulation System consists of panels of expanded polystyrene (EPS) foam, available in a number of dimensions that work well with most form systems. The panels are set within the wall forms prior to the concrete pour, and are held in place by a patented web structure that weaves throughout the concrete. The resulting walls thus consist of a concrete layer and an attached insulation panel, with fastening strips on the exposed face to facilitate application of drywall or other finish materials. Depending on the thickness of the concrete, R-values range from 9.6 to 11.7. Panels are termite-resistant, odor-free, and contain no CFCs, HCFCs, HFCs, or formaldehyde. The UL-approved system is IECC code-compliant for foundation walls, and meets ASTM C578 Type 1 and ICC-ES EG239 requirements for below-grade use.
Once the concrete cures, the forms are removed to reveal a wall surface that is fully insulated. The ThermaEZE webs incorporate fastening strips on the exposed face to facilitate application of finish materials like drywall. ThermaEZE is suitable for both interior and exterior walls; consult local building codes for interior finish requirements.
