A multi-sheet glazing unit includes a closed spacer frame, the spacer frame has one side having a pair of legs joined to a base to provide the spacer frame with a U-shaped cross-section. An inner sheet has an edge mounted in an edge receiving member mounted between the legs of the U-shaped side of the spacer frame.
