A multiple pane glass unit for butt-glazing comprising an exterior glass sheet spaced apart from an interior glass sheet by horizontal head and sill spacers and a pair of vertical structural spacers, with the vertical spacers being constructed and arranged to provide structural support for the glass sheets against wind loads and the like and a first gasket strip mounted on a first vertical structural spacer, with a second, mating gasket strip mounted on a second vertical structural spacer, with the first and second gasket strips being arranged to contact one another along the vertical joints of side-abutting glass units to form a butt joint and being constructed and arranged to be substantially flush with the exterior glass sheets and to provide a weatherseal joint along the abutting vertical edges thereof, said gaskets being applied to the glass unit prior to installation and eliminating the need for an exterior applied wet weatherseal.

A multiple pane glass unit comprising an exterior glass sheet having spaced-apart horizontal and vertical edge portions an interior glass sheet having horizontal and vertical edge portions aligned with said horizontal and vertical edge portions of said portions of said exterior glass sheet, a horizontal head spacer located between aligned horizontal edge portions of said exterior and interior glass sheets, a horizontal sill spacer positioned between aligned horizontal edge portions of said glass sheets, a pair of vertical spacers positioned between aligned vertical edge portions of said exterior and interior glass sheets, said horizontal and vertical spacers being interconnected at their ends and being secured to the glass sheets at the edge portions thereof for spacing said glass sheets apart, said vertical spacers being constructed and arranged to provide structural support for the glass sheets against wind loads or the like, said vertical spacers including a first channel member extending along one pair of aligned vertical edge portions of the glass sheets and a second channel member extending along the other pair of aligned vertical edge portions of the glass sheets, said first channel member including a first leg portion which extends along the vertical edge portion of the associated exterior glass sheet and a second leg portion which extends along the vertical edge portion of the associated interior glass sheet, said second channel member including a first leg portion which extends along the vertical edge portion of said associated exterior glass sheet and a second leg portion which extends along the vertical edge portion of said associated interior glass sheet, said first and second channel members being mounted substantially entirely within the .interior of the spaced-apart glass sheets, and gasket means attached to said first leg portions of said first and second channel members for use in sealing the exterior vertical joint between adjacent glass units on installation thereof in abutting relation, said gasket means including a first gasket strip mounted on the first leg portion of said first channel member and a second gasket strip mounted on the first leg portion of the second channel member, said first and second gasket strips being arranged to contact one another along the vertical joints of side-abutting glass units to form a butt joint and being constructed and arranged to be substantially flush with the exterior glass sheets and to provide a weather-seal joint along the abutting vertical edges thereof.
