The construction of a window, and in particular the insulating glass (IG) unit, is often a detail that is important to educate the customer about.  This triple pane corner cut window sample allows you to "look inside" the IG to understand how the window is assembled.  The window uses 1/4" super spacer technology and is constructed of three 1/8" panes of clear (uncoated) glass.  The length of the two sides of the window is 6 inches long with a thickness of 0.86 inches.
