Our classic panel consists of a foamed polyurethane core surrounded by a profiled steel exoskeleton on all four sides
This state-of-the-art box construction is unique to Enerpan, giving the panel exceptional rigidity and bend strength under load. Add up to 4 inches of environmentally-safe polyurethane for an R-value up to 31.6.
