Abstract
Refrigeration units such as walk-in coolers and freezers, particularly interlocking insulative panels used in construction of such units. The individual insulative panels are characterized by a densified urethane perimeter and a core of low density insulating urethane abutting the perimeter and held in place by a thin outer skin. The densified urethane perimeters of the panels have a tongue-in-groove configuration, as well as a cam locking means, securing abutting panels together.
