Abstract
Vacuum insulation panels include an insulating media made up of glass fibers having a carbonized asphalt coating thereon. When such carbon-coated glass fibers are used as fillers for metal jacketed vacuum insulation panels, the resulting panels can be used for substantially higher temperature applications. The carbon on the carbon-coated fibers can be activated to absorb any outgassing that occurs from the insulation media within the panels to help ensure satisfactory vacuum levels over time.
