ABSTRACT:
A corner piece for connecting adjacent hollow spacer members to form a spacer frame used in the construction of thermally insulated windows. The corner piece includes horizontal and vertical legs forming a right angle. One end of each leg has a cutting edge. When the ends of each leg are inserted into a hollow spacer which has internal partitions, the sharpened cutting edge is able to cut around the adjacent partition and thus enter the spacer fully. The corner piece is constructed in a manner which permits sealant to be injected into the corner pieces and the spacers after assembly to seal off any gaps around the installed corner piece.
