Royal Prestige® Cookware - 9-Ply Health Systems™

The innovative 9-ply Thermal Deluxe cookware incorporates a wall of air within the stainless steel sides of the cookware. This wall functions as insulation, which prevents heat loss during and after cooking. The technique used in creating this thermal wall is exclusive to Royal Prestige®. Only the Thermal Deluxe Health System™ features nine plies that flow up into the sides of the cookware, followed by a thermal wall.
