Abstract:
A method of fabricating an insulating unit comprising the steps of:providing a pair of sheets;providing a substrate;forming the substrate into at least one spacer section having a base and a pair of outer legs connected to the base, the at least one spacer section having a surface designated as a supporting surface, and having a structural stability sufficient to maintain the pair of sheets spaced from one another;providing a bead on the supporting surface, the bead provided on the supporting surface includes a moisture pervious adhesive having a desiccant therein, the bead at least when provided on the supporting surface having a structural stability to maintain the pair of sheets spaced from one another less than the structural stability of the spacer section, andassembling a spacer frame that includes the at least one spacer section and the sheets to provide an insulating unit having the pair of sheets in a fixed spaced relationship to one another with the spacer frame therebetween to provide a compartment defined by the sheets and portions of the spacer frame wherein the moisture pervious adhesive having the desiccant communicates with the compartment.
