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.

A vacuum insulation panel containing a volume of microporous insulating material and having a useful life measured in years, comprising: a semi-rigid thermoformed container made of a material impervious to gases and moisture and having a central receptacle area with an open top for receiving said volume of said microporous insulating material and being bounded by a peripheral ledge area; a porous layer providing a boundary between ambient atmosphere and said volume of microporous insulating material in said receptacle, said porous layer permitting passage of gases and moisture, but preventing passage of said microporous insulating material; and an impermeable layer sealingly received along the entire peripheral ledge area to close said top after said receptacle area and volume of microporous insulating material has been evacuated of gases and moisture, to prevent entry of gases and moisture into said receptacle during the useful life of said panel; said container and impermeable layer both being formed of a material such that said panel, when sealed closed, is able to maintain an evacuation pressure level of approximately 20 mm Hg for several years.
