An insulating cell element comprises a hermetically sealed shell defining a closed chamber having a volumetric space contained by the chamber wall. The space has a vacuum established in an amount sufficient to achieve a heat conductivity of substantially zero through the space. The shell has a structural configuration effective to resist the outside pressure resulting when the vacuum is established in the closed chamber and is further effective to maintain the vacuum over a substantially unlimited period of time. The energy transfer for a single layer of these elements is down to at least about 0.050 BTU per square foot per degree Fahrenheit (°F.) at an overall thickness of about ⅛of an inch. A plurality of the insulating cell elements are contiguously disposed with respect to each other to form a monolithic structure.

A thermal insulation structure comprising: (a) a plurality of insulating cell elements contiguously disposed with respect to each other to form a monolithic structure, (b) each of the insulating cell elements including a hermetically sealed shell defining a closed chamber having a volumetric space with a vacuum established in an amount sufficient to achieve a minimal heat conductivity through said space, (c) each of the shells having a structural configuration effective to resist the outside pressure resulting when said vacuum is established in the closed chamber and being further effective to maintain said vacuum over a substantially unlimited period of time, (d) each shell being separate and independent with respect to each other to form individual cell elements whereby the loss of vacuum in any single chamber does not adversely affect the vacuum conditions in a contiguously disposed insulating cell element, (e) the monolithic structure having a heat transfer of down to at least about 0.050 Btu\s per square foot at an overall thickness of about ⅛of an inch.
