Flexibility for structure
The panels used in our chamber are 4” (100mm or 150mm) Thick urethane-foam sandwiched between a stainless-steel interior wall and a coated-steel exterior. An assembled box is self-supporting. So that no heavy structural members are required. Different door sizes, flooring upgrades,access ports, and other modifications are possible.
