Abstract
An insulation panel comprises an insulation board of glass fibers and a partially evacuated gas-tight envelope encapsulating the board, where, prior to the evacuation of the envelope, the board has been subjected to a heat setting process in which the board is raised to a heat setting temperature above the strain temperature of the glass but below the softening temperature of the glass and to a pressure applied by opposed platens followed by a quick release of the board from the platens prior to substantial cooling of the board.
