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.

A multi-sheet glazing unit includes a spacer frame having a pair of legs joined to a base to provide a U-shaped cross-section. A sheet e.g. glass sheet is secured by a moisture-impervious adhesive to the outer surface of each of the legs of the spacer frame. A plurality of sheet retaining members in a spaced relationship to one another is maintained on the legs of the spacer frame between the glass sheets and spaced from the base. The sheet retaining members each have a pair of flexible fingers mounted on a platform member, angled away from the platform member toward one another and spaced above the platform member. A sheet mounted between the fingers is maintained spaced from the outer sheets. A method for making the unit is also disclosed.
