ABSTRACT:
A thermoformed vacuum insulation container is provided for use in a vacuum insulation panel. The container is preformed to have a receptacle area for receiving a quantity of microporous insulation material as well as a peripheral ledge area. The microporous insulating material is isolated by a porous sheet material which is either sealed to the ledge area covering the receptacle area, or completely bounds the microporous insulation material in the form of a pouch or sack. An impermeable layer is sealed to the ledge area following evacuation of the receptacle area and microporous insulation material of gases and moisture in order to complete the evacuated panel.
