Abstract (en)
[origin: WO2008124414A1] The present invention is directed to a lightweight, gas-filled, highly insulative cellular structure and methods for manufacturing the cellular structure. The cellular structure can be incorporated into outdoor gear and apparel to make the outdoor gear or apparel warm, while still maintaining a desired thinness and flexibility. The insulative article takes advantage of the superior insulative properties of dry gases and preferably highly insulative gasses such as argon. In addition, the size and shape of the cells in the cellular structure are selected to minimize convection.
