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. The remaining edges of the inner sheet are within the interior of the closed spacer frame and spaced from the spacer frame. The inner sheet is held within the spacer frame by sheet retaining members mounted to the spacer frame. A sheet e.g. glass sheet is secured by a moisture-impervious adhesive to outer surface of each of the legs of the spacer frame. One type of sheet retaining members has a horizontal member and a vertical member, and a locking member. The locking member is mounted on the horizontal member spaced from the vertical member to form a groove to hold the inner sheet within the closed interior of the spacer frame. Another type of the sheet retaining member includes a pair of flexible fingers mounted on a platform member, angled away from the platform member toward one another and having their ends spaced from one another to provide a groove to hold the inner sheet within the closed interior of the spacer frame. A method for making the unit is also disclosed.

[ What is claimed is:] [1.] A multi-sheet glazing unit comprising:a closed ended parallelepiped spacer frame having an interior space, each side of the spacer frame having a pair of spaced outer legs joined by a base, outer surface of one of the spaced legs lying in a first plane, outer surface of other one of the spaced legs lying in a second plane, the first and second planes generally parallel to and spaced from one another, outer surface of the base lying in a third plane and a fourth plane generally parallel to and spaced from the third plane with the third and fourth planes transverse to the first and second planes with the pair of spaced outer legs between the third and fourth planes and the fourth plane of each side of the spacer frame defining perimeter of the interior space and at least one side of the spacer frame having a generally U-shaped cross section defined as the first side of the spacer frame;a pair of outer sheets spaced from one another with the outer surfaces of the legs facing adjacent one of the pair of outer sheets and the spacer frame therebetween;adhesive securing the outer sheets in a fixed spaced relationship about the spacer frame;an inner sheet having four sides sized to have peripheral and marginal edge portions of one side inserted between the outer legs of the first side of the spacer frame and intersecting the fourth plane and remaining peripheral and marginal edge portions of the inner sheet within the interior space of the closed spacer frame, andat least one clip mounted on at least one of the remaining sides of the spacer frame to receive and engage peripheral and marginal edge portions of adjacent side of the inner sheet to maintain the inner sheet in position within the interior space of the spacer frame between the outer sheets.
