In most cases, at least prior to pivoting the glass panel 11, at least some of the interior finish surround 78c, 78d is removed from around the interior of the right side member 14c and left side member 14d, to allow the glass panel 11 to be pivoted interiorly. Also, if the window assembly 10 includes a fin member 58, the fin member 58 is removed by removing the fasteners attaching the fin member 58 to the shelf portions 52a, 52b, and removing the structural adhesive 94.
In an alternative method, the glass panel 11 may be removed to the exterior of the window frame 12 by removing the respective exterior retainers 68c, 68d from the respective interior retainer attachments 62c, 62d of the right side member 14c and left side member 14d. Then, the glass panel 11 is removed similarly to method described above, except that the bottom edge of the glass panel 11 is pivoted exteriorly, and the glass panel 11 is removed to the exterior of the window frame 12. Similar to the method above, at least prior to pivoting the glass panel 11, at least some of the exterior finish surround 79c, 79d is removed from around the exterior of the right side member 14c and left side member 14d, to allow the exterior retainers 68c, 68d to be removed and to allow the glass panel 11 to be pivoted exteriorly.
Another method is directed to removing a glass panel 11 comprising multiple glass panes 84a, 84b attached edge to edge using structural adhesive from an installed window assembly 10 with finish surround 78, 79 installed around an entire interior and exterior of the installed window assembly 10. The method includes detaching the first glass pane 84a from the and second glass pane 84b removing the structural adhesive 94. The first glass pane 84a is removed from the window assembly 10 by first moving the first glass pane 84a sideways out of the right side member 14c (i.e., sliding it to the left, as viewed from the exterior, which moves the right edge of the first glass pane 84a out of the right side member 14c. The first glass pane 84a is moved upward into the edge space 104a in the head member 14a and then is pivoted to move the bottom edge of the first glass pane 84a interiorly out from the sill member 14b. The first glass pane 84a is moved downward to remove the top edge of the first glass pane 84a out from the head member 14a. The second glass pane 84b is removed from the window assembly 10 similarly, except that it is moved sideways out of the left side member 14d (i.e., sliding it to the right, as viewed from the exterior). In a very innovative aspect of this method of removing the multi-paned glass panel 11, the entire glass panel 11 is removed without removing any of the finish surround 78, 79, including not removing any of the finish surround 78c, 78d from around the interior of the right side member 14c and left side member 14d.
If the glass panel 11 comprises one or more additional interior panes 84 attached edge to edge between the first glass pane 84a and second glass pane 84b, they may be removed by simply moving the interior glass pane 84 upward into the edge space 104a in the head member 14a and pivoting the interior glass pane 84 to move the bottom edge of the interior glass pane 84 interiorly out from the sill member 14b. Then, the interior glass pane 84 is moved downward to remove the top edge of the interior glass pane 84 out from the head member 14a.
In alternative methods of removing the glass panel 11 from the window assembly 10, any one or more of the exterior retainers 68a, 68b, 68c, 68d and/or interior retainers 76c, 76d may be removed prior to removing the glass panel 11 or glass panes 84 of the glass panel 11. Removing one or more retainers 68, 76 may facilitate moving the glass panel 11 or glass panes 84 within the frame members 14, and also pivoting and removing the glass panel 11 or glass panes 84.
