Abstract
A substrate having a bead of a moisture and/or gas pervious adhesive having a desiccant therein is shaped to provide U-shaped spacer stock. The spacer stock is bent to provide a spacer frame having continuous corners.
Claims8
A strip to be shaped into spacer stock for maintaining adjacent glass sheets of an insulating unit in a predetermined spaced relationship to one another, the strip comprising:
- an elongated flat bendable metal substrate having opposed major surfaces, at least one of the surfaces being fluid impervious, said substrate having a structural stability sufficient to maintain adjacent glass sheets in the fixed relationship when said substrate is shaped into the spacer stock;
- an elongated bead of fluid pervious adhesive adhered directly to one of said major surfaces spaced from edges of said substrate, said adhesive having structural stability less than the structural stability of said substrate;
- and
- a desiccant in said bead.
