Patent number: 5527411Abstract: Improved insulating modular panels are manufactured to incorporate into each insulating modular panel at least one vacuum insulation panel. Vacuum insulation panels are conveyed seriatim toward a pultrusion die which ultimately produces the insulating modular panels as a continuous block. Joint spacings or gaps between adjacent vacuum insulation panels and sides of the vacuum panels are filled with foam or preformed filler material to form a substantially continuous inner core which has substantially continuous side edges. Reinforcement material is applied to the inner core. The reinforcement material can be impregnated with resin prior to its application to the inner core or resin may be injected into the pultrusion die. In either event, a continuous elongated block of insulating modular panels emerges from the pultrusion die. The continuous elongated block is severed at joint spacings or gaps between adjacent vacuum insulation panels to form insulating modular panels of desired sizes from the block.Type: GrantFiled: March 31, 1995Date of Patent: June 18, 1996Assignee: Owens-Corning Fiberglas Technology, Inc.Inventor: Ralph B.
