U.S. Cooler’s® foamed-in-place polyurethane performance rating of R-32 for freezers meets the Energy Independence and Security Act and exceeds the R-25 requirement for coolers. It’s 97% closed cell structure resists moisture from seeping into the insulation which helps maintain the high R-value. By utilizing state of the art horizontal presses and technology, panels lie flat during the foaming process which reduces voids in the insulation . The panels’ structural tongue and groove, cam-locking system provides an air-tight seal between the panels restricting air infiltration into the insulation core. Foamed-in-place polyurethane manufacturing techniques present an uniform adhesion to the metal skins causing the insulation to continuously adhere.
U.S. Cooler’s® polyurethane walk-in products are made with the same exceptional quality and performance construction that has proven successful in the industry for over 25 years. Every walk-in is pre-assembled in our manufacturing facility before shipment to ensure precise quality control and ease of assembly in the field.
