A method for making a glazed unit having three sheets. The unit includes a pair of outer glass sheets secured to outer legs of a spacer having a generally U-shaped cross section. On the base of the spacer between the outer legs is provided a layer of pliable material having a generally U-shaped cross section and having a desiccant therein. A third or intermediate glass sheet has its edge portion in the groove formed by the layer of pliable material. Movement of the third sheet toward an outer glass sheet is limited by the cooperation of the layer of the pliable material and portion of the outer legs of the spacer at the corners of the unit bent inwardly to move the layer of pliable material at the corner toward the unit during fabrication of the unit.

A method of making an insulating glazing unit having at least three sheets comprising the steps of: providing three sheets, two of the sheets defined as a first outer sheet and a second outer sheet, and the third sheet defined as an intermediate sheet; providing a flat substrate having opposed edges

A method of making an insulating glazing unit having at least three sheets comprising the steps of: providing three sheets, two of the sheets defined as a first outer sheet and a second outer sheet, and the third sheet defined as an intermediate sheet; providing a flat substrate having opposed edges and a leading end between the opposed edges and a major surface between the opposed edges with center portion of the major surface between and spaced from the opposed edges defined a receiving surface; shaping the flat substrate to provide a spacer having a predetermined length, a base, a first outer leg extending upwardly from the base, a second outer leg extending upwardly from the base and spaced from the first outer leg to provide the spacer with a general U-shaped cross section wherein surface of the base facing the space between the first and second outer leg is the receiving surface; flowing a layer of a pliable material onto the receiving surface the layer having spaced raised portions with a depression between the spaced raised portions, the depression defined as a groove; encircling the intermediate sheet with the spacer while positioning the peripheral edge portions of the intermediate sheet in the groove to provide a spacer frame about the intermediate sheet where the first and second outer legs of the spacer are first and second outer legs respectively of the spacer frame, wherein during the practice of the encircling step the spaced raised portions of the layer of the pliable material limit movement of the intermediate sheet toward outer legs of the spacer frame; and securing the outer legs of the spacer frame and the outer sheets together to provide respective compartments between one of the outer sheets and the intermediate sheet and the other outer sheet and the intermediate sheet.
