This paper presents the design, material characteristics, and thermal performance of a new insulating material. Development of this material is motivated by the need for non-CFC based high performance insulations with applications for refrigeratorlfreezer and building walls. This suyr insulating gas filled panel technology achieves R-values of between 8 hr-ft2-F/Btu per inch and 15 hr-ft2-F/Btu per inch (one to two times that of CFC blown foams and two to four times that of fiberglass insulations) at estimated costs of $0.40 -$1.50/in-ft2. Prototypes have been built using commercially available materials and components, tested by the developers, and sent to an independent laboratory for independent thermal performance testing.
