An insulative, gas impermeable spacer frame is provided for the precision separation of two or more transparent glass or plastic panes, and is hermetically sealed in place to prevent the ingress or egress of moisture vapor, and to contain various noble gases, or air, between the adjacent panes, being used in insulated lights for windows and doors. The spacer is made of insulative organic material of suitable stiffness such as cardboard, or plastic over which is applied a coating or lamination of gas and moisture vapor barrier materials, thus forming a composite insulative web which may be fabricated into tubular structures to form separate frame units. Such spacer structures may possess extremely low thermal conductivity, so as not to constitute a thermal bridge between the panes being separated, thereby diminishing and even eliminating the problem of window edge frosting and/or peripheral dew point development, such as occurs when metal spacer devices are used. The hollow, tube-like spacer form may be used to contain desiccant materials for absorbing moisture and an organic vapors that evolve or may be present within the hollow window cavity, created when the spacer is sealed in place. The material or materials for the improved insulating spacer may be supplied in a flexible, planar, ribbon-like form, of continuous length rather or as a preformed stiff section, as at present, thus enabling the economic advantages of making various sizes of spacer frames without the cut-off losses which otherwise occurs when such spacer assemblies are cut from stock lengths of rigid, preformed hollow profile. However, the provision of the unique spacer, made up into predetermined lengths also is contemplated. The rigid stock lengths are then readily square cut or mitered and jointed with insert joints, to form insulating spacer frames. The provision of a protective film, against ultra violet degradation may also be readily incorporated in the spacer or coating formulation.

In combination, a multi-pane glazing unit having at least two glazing panes in mutually spaced relation and a composite insulative spacer for the precision separation of said glazing panels in substantially mutually parallel, hermetic sealed relation, comprising a low cost substantially porous, homogeneous resilient web substrate having a coefficient of thermal expansion substantially equal to or less than that of said glazing panels, said web substrate serving, in use, to hold said glazing panels apart, being subject to gas percolation therethrough and being faced with at least one overcladding layer of gas impermeable barrier material selected from the group consisting of polyvinyl alcohol, polyvinylidene chloride, thermoplastic polyesters, ethylene vinyl alcohol copolymers, a thermally isolated thin metallic coating, and combinations thereof, applied in sealing relation to a selected surface of the substrate, said spacer being edge sealed to said panels to enclose and hermetically seal a gas retaining space between said glazing panels.
