ABSTRACT:
A glazed unit having three sheets 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 is also disclosed for making the triple glazed unit and for filling the compartments between the sheets with an insulating gas e.g. Argon.
