• Better heat retention using styrofoam with layers of air.
• Panasonic’s patented technology from Japan – curve-shaped styrofoam slows down heat transfer.
• The curved shape creates small air pockets that block the flow of heat transfer which minimises heat loss.
What is Styrofoam?
A type of heat insulation material that forms an air layer to prevent heat loss.
