The innovative 9-ply Thermal
Deluxe Health System 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.
