ABSTRACT:
A spacer stock has a pair of outer legs joined by a base to provide the spacer stock with a generally U-shaped cross section. The outer legs are formed e.g. each leg has a pair of members having a hairpin cross section to reduce the degree of torsional twist of the spacer stock and/or spacer frame with the legs preferably only connected by the base having only one thermal conducting path e.g. through the base from one leg to the other leg. The spacer stock may be shaped or sections of spacer stock joined to provide a spacer frame. The spacer frame may be used to fabricate a multi-sheet glazing unit e.g. by securing a sheet to each of the outer legs with moisture impervious adhesive or sealant.
