Solid dark line on chart indicates maximum frame height possible for a given maximum panel width with double glazing.
Broken line on chart indicates maximum frame height possible for a given maximum panel width with single glazing.

The total number of panels in a unit is only restricted by structural steel consideration. Any custom size is possible up to the maximum size shown.

The maximum size limits are based on the weight of a double glazed panel that has a net glass thickness of 5/16" (8 mm). This glass is insulated and each pane is 5/32" (4 mm). For other net glass thickness, this maximum size limit chart will not apply.
