A multiple pane glass window unit comprising an outboard glass sheet spaced apart from an inboard glass sheet, spacer members positioned between and connected to the horizontal and vertical portions of the glass sheets to space them apart, said spacer members including a horizontal head spacer member connected to a horizontal sill spacer member by a pair of spaced-apart vertical side spacer members, said vertical side spacer members spacing apart the glass sheets and stiffening and supporting the side edge portions of the glass sheets against pressures of wind and rain and the elements, and factory-affixed gasket members attached to the vertical edges of the side spacer members for sealing the vertical space between side-abutting window units, said gasket members being adapted to be compressed between the sides of side-abutting window units, said side spacer members including a side spacer member that is U-shaped in cross-section with the legs of the U facing sideways from the window unit, a foam spacer tape adhered to the edge portions of the legs of the side spacer member and to the side edge portion of the outboard glass sheet, and adhesive layers sealing the side spacer legs to the interior surface of the glass sheets, whereby the sides of abutting window units may be sealed by placing the sides close enough together that they compress the foam spacer tape between them, and whereby the window units may be installed from the inside of the building. In the space formed between the vertical edges on the inside glass of two-abutting units and the inside edges of the factory-affixed gasket members silicone caulking is applied at the time of installation to completely seal the vertical joint between units.

A multiple pane glass window unit comprising an outboard glass sheet spaced apart from an inboard glass sheet and having horizontal and vertical edge portions, a horizontal head spacer member connected to a horizontal sill spacer member by a pair of spaced-apart vertical side spacer and stiffener means for spacing apart the glass panes and stiffening the multiple pane glass unit, said vertical side spacer and stiffener means being positioned between and connected to the glass sheets at the vertical edge portions of the glass sheets to space them apart and protect the edge of the glass sheets from damage, said vertical side spacer and stiffener means being U-shaped with a pair of legs extending from a base portion, said vertical side spacer and stiffener means being mounted at the vertical peripheral edges of the glass sheets with the edges of said legs substantially flush with the vertical peripheral edges of the glass sheets and mounted solely within the interior of the glass sheets, and gasket means attached to the vertical edges of said legs for sealing the vertical space between side-abutting window units, said gasket means being adapted to be positioned and compressed between the vertical sides of side-abutting window units, whereby the window units may be installed from the inside of a building.
