摘要： A method of forming an insulation panel with an insulating core sealed within an envelope. The envelope formed from a single sheet of highly flexible material with a pair of opposing edge portions sealed together contiguously along the entire respective lengths thereof to form a sleeve with a single and two open ends. The sleeve may be folded to define sides. A longitudinal pleat may be formed in at least one of the sides of the envelope. One open end is sealed to form an envelope and a core of insulation material is inserted. The remaining open end is sealed and the envelope is evacuated.
