Suitable for above- and below-grade applications, the ThermaEZE thermal insulation system consists of expanded polystyrene foam panels. The panels are set within the wall forms prior to placing the concrete, and are held in place by a patented web structure that becomes embedded in the concrete, cutting labor time. Because there are no gaps between the insulation and concrete, moisture and mildew resistance is heightened. Certain-Teed Corp. 800-233-8990.
