ABSTRACT:
The present invention provides a multi-sheet unit with a spacer frame having at least three sides, at least three corners, a first sheet supporting surface and an opposite second sheet supporting surface. The spacer frame includes a spacer stock member having a first end, an opposite second end, the at least three sides and at least two corners of the at least three corners; a corner key comprising a bendable elongated body having a first end in the first end of the spacer stock member, an opposite second end in the second end of the spacer stock member to provide one of the corners of the at least three corners of the spacer frame, and a cut out between the ends of the corner key, the ends of the corner key bendable relative to one another to decrease the spacing of the cut out; a first sheet secured to the first sheet supporting surface by a first moisture and/or gas impervious layer, and a second sheet secured to the second sheet supporting surface by a second moisture and/or gas impervious layer.
