A multi-sheet glazing unit has a pair of outer glass sheets spaced from one another and secured to a spacer frame having a generally U-shaped cross section defined by outer legs secured to a base. The recess of a sheet retaining member is mounted on peripheral edge portions of an intermediate glass sheet. The intermediate glass sheet and sheet retaining member are mounted within the outer legs of the spacer frame to position the intermediate sheet between and spaced from the outer sheets. A method of making multi-sheet units is also disclosed.
