A window construction set in a pre-existing frame includes upper and lower horizontal channel members that respectively engage horizontal top and bottom edges of at least two window panes and first and second laterally spaced vertical channel members that respectively engage vertical outboard edges of the window panes. Each channel member is secured to a corresponding part of the frame and a structural shim is sandwiched between each channel member and its associated frame. The preferred embodiment includes multiple window panes disposed in lateral relation to one another so that all panes are secured at their top and bottom edges and two outboard window panes are further secured along their respective vertical outboard edges. Respective abutting inboard vertical edges of contiguous window panes are joined together by respective strips of silicone, there being no vertical frame members between abutting contiguous window panes.

1. A window construction, comprising: a header structure that engages a top edge of at least two window panes disposed in lateral, edge-abutting relation to one another, said header structure adapted for mounting to a horizontally disposed, upper perimeter frame;a footer structure that engages a bottom edge of said at least two window panes, said footer structure adapted for mounting to a horizontally disposed, lower perimeter frame;a first jamb structure that engages an outboard end of a first window pane of said two window panes, said first jamb structure adapted for mounting to a vertically disposed, first side perimeter frame;a second jamb structure that engages an outboard end of a second window pane of said two window panes, said second jamb structure adapted for mounting to a vertically disposed, second side perimeter frame;said header structure including a horizontally-disposed, downwardly-opening U-shaped channel having a lateral extent substantially equal to a combined lateral extent of said at least two window panes;said footer structure including a horizontally-disposed, upwardly-opening U-shaped channel having a lateral extent substantially equal to the lateral extent of said two window panes;said first jamb structure including a first vertically-disposed U-shaped channel that extends from said downwardly-opening U-shaped channel to said upwardly-opening U-shaped channel at an outboard end of said first window pane;said second jamb structure including a second vertically disposed U-shaped channel that extends from said downwardly-opening U-shaped channel to said upwardly-opening U-shaped channel at an outboard end of said second window pane;said respective U-shaped channels of said first and second jamb structures opening towards one another;a strip of silicone disposed between contiguous vertical free edges of said at least two laterally disposed, edge-abutting window panes;said single frame holding at least two laterally disposed, edge abutting window panes;each of said window panes formed of three laminations;said three laminations including an exterior pane having a thickness of about a quarter inch (¼″), a middle pane having a thickness of about three-eighths of an inch (⅜″), and an interior pane having a thickness of about three-eighths of an inch (⅜″);there being no frame where said two laterally disposed, edge-abutting window panes abut one another. 2. The window construction of claim 1, further comprising: a first structural shim positioned between a top wall of said horizontally-disposed, downwardly-opening U-shaped channel and a bottom wall of said upper perimeter frame;a second structural shim positioned between a bottom wall of said horizontally-disposed, upwardly-opening U-shaped channel and a top wall of said lower perimeter frame;a third structural shim positioned between a bottom wall of said vertically-disposed U-shaped channel of said first jamb structure and said first side perimeter frame;a fourth structural shim positioned between a bottom wall of said vertically disposed U-shaped channel of said second jamb structure and said second side perimeter frame;said downwardly-opening U-shaped channel secured to said bottom wall of said upper perimeter frame with said first structural shim member being sandwiched between said downwardly-opening channel and said upper perimeter frame;said upwardly-opening U-shaped channel secured to said top wall of said lower perimeter frame with said second structural shim member being sandwiched between said upwardly-opening channel and said lower perimeter frame;said first vertically disposed U-shaped channel secured to said first vertically disposed side perimeter frame with said third structural shim member being sandwiched between said first vertically disposed U-shaped channel and said second vertically disposed side perimeter frame;said second vertically disposed U-shaped channel secured to said second vertically disposed perimeter frame with said fourth structural shim member being sandwiched between said second vertically disposed U-shaped channel and said second vertically disposed side perimeter frame. 3. The window construction of claim 2, further comprising: a first strip of silicone disposed along an exterior lateral extent of said first structural shim and a second strip of silicone disposed along an interior lateral extent of said first structural shim;a first strip of silicone disposed along an exterior lateral extent of said second structural shim and a second strip of silicone disposed along an interior lateral extent of said second structural shim;a first strip of silicone disposed along an exterior lateral extent of said third structural shim and a second strip of silicone disposed along an interior lateral extent of said third structural shim; anda first strip of silicone disposed along an exterior lateral extent of said fourth structural shim and a second strip of silicone disposed along an interior lateral extent of said fourth structural shim. 4. The window structure of claim 1, further comprising: said first and second window panes being disposed in a common plane. 5. The window structure of claim 1, further comprising: said first and second window panes being disposed at an angle relative to one another that is between approximately one hundred thirty five degrees and one hundred eighty degrees (135°-180°). 6. The window structure of claim 1, further comprising: a strip of silicone disposed between an exterior wall of said horizontally-disposed, downwardly opening channel and respective upper exterior edges of said at least two window panes and a strip of silicone disposed between an interior wall of said horizontally-disposed, downwardly opening channel and respective upper interior edges of said at least two window panes;a strip of silicone disposed between an exterior wall of said horizontally-disposed, upwardly opening channel and respective lower exterior edges of said at least two window panes and a strip of silicone disposed between an interior wall of said horizontally-disposed, upwardly opening channel and respective lower interior edges of said at least two window panes;a strip of silicone disposed between an exterior wall of said first vertically-disposed, inwardly opening channel and an exterior surface of said first vertically disposed outboard edge of a first window pane and a strip of silicone disposed between an interior wall of said first vertically-disposed, inwardly opening channel and an interior surface of said first vertically disposed outboard edge of said first window pane;a first strip of silicone disposed between an exterior wall of said second vertically-disposed, inwardly opening channel and an exterior surface of said second vertically disposed outboard edge of a second window pane and a strip of silicone disposed between an interior wall of said second vertically-disposed, inwardly opening channel and an interior surface of said second vertically disposed outboard edge of said second window pane.
