Gas-Filled Panels Gas-Filled Panels, or GFPs, use thin polymer films and low-conductivity gas to create a device with extraordinary thermal insulation properties. GFPs are essentially hermetic plastic bags that can take on a variety of shapes and sizes. Inside the outer barrier is a cellular structure called a baffle. Argon gas filling provides an effective thermal resistance level of R-7 per inch, krypton gas provides R-12.5 per inch, and xenon gas provides R-20 per inch. Energy use of domestic refrigerator/freezers is directly influenced by the overall thermal performance of the cabinet and doors. An advanced thermal insulation technology can improve the efficiency of appliances such as refrigerators. Insulation materials are critical in buildings designed for low energy use and good thermal comfort. Increasing the thermal resistance, or R-value, of the insulation is an effective strategy to lower heating costs when thermal loads are dominated by the building envelope. Thermal insulation will be increasingly important in the future development of cars because significant improvements in gas mileage can be achieved by downsizing the heating, ventilation, and air conditioning equipment. Waste reduction and higher thermal performance compared to close-cell foam is possible using Gas-Filled Panels. The panels feature low mass and low volume.
