Abstract
Abstract An insulation panel comprises a mineral fiber board having a density between 8 and 28 pounds per square foot, the fibers having no organic binder thereon, and between 5 and 40 percent by weight of particulate material packed in the interstices of the board, and a gas-tight envelope encapsulating the board, the envelope being evacuated to a vacuum between 10 -4 Torr and 10 Torr.
