1. A method of fabricating a spacer frame for maintaining two sheets in spaced relation comprising the steps of:providing a piece of spacer stock of sufficient length to provide the spacer frame, the spacer stock having at least a pair of side walls joined by a base to provide the sidewalls and base with a U-shape, the spacer stock having a bead of a moisture pervious material having a desiccant therein in contact with surface of the base between the sidewalls defined as inner surface of the base, the bead having structural stability less than the structural stability of the spacer stock; bending the piece of spacer stock to form the spacer frame, while maintaining the bead on the inner surface of the base during the practice of the bending step.
