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.

An insulation panel comprising a heat set insulation board of compressed 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 glass fiber 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 within the range of from about 10 psi (69 kPa) to about 50 psi (345 kPa) followed by a quick release of the board from the platens prior to substantial cooling of the board.
An insulation panel comprising a heat set insulation board of compressed 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 glass fiber board is raised to a heat setting temperature at least 20 degrees C. above the strain temperature of the glass but at least 80 degrees C. below the softening temperature of the glass, and to a pressure applied by opposed platens within the range of from about 10 psi (69 kPa) to about 50 psi (345 kPa) followed by a quick release of the board from the platens prior to substantial cooling of the board.
An insulation panel comprising a heat set insulation board of compressed glass fibers and a partially evacuated gas-tight envelope encapsulating the board, the gas-tight envelope having an absolute internal pressure within the range of from 10.sup.-5 to about 10.sup.-1 torr, where, prior to the evacuation of the envelope, the board has been subjected to a heat setting process in which the glass fiber board is raised to a heat setting temperature at least 20 degrees C. above the strain temperature of the glass but at least 80 degrees C. below the softening temperature of the glass, and to a pressure applied by opposed platens within the range of from about 10 psi (69 kPa) to about 50 psi (345 kPa) followed by a quick release of the board from the platens prior to substantial cooling of the board.
