Abstract
A method for creating a vacuum insulated panel including preforming a continuous insulation member having male and female engaging surfaces and providing a barrier film envelope having an opening. The insulation member is disposed within the barrier film envelope and a tooling fixture is pressed against the barrier film envelope to press the barrier film envelope against the male and female engaging surfaces to remove gas from between the barrier film envelope and the male and female engaging surfaces. Substantially all gas is removed from within the barrier film envelope so that the barrier film envelope substantially conforms to an exterior surface of the insulation member. The opening of the barrier film envelope is then hermetically sealed, wherein the barrier film envelope forms a continuous layer over the core insulation member to form a vacuum insulated panel.
