Overview
Plan the panel divisions around the opening width and the existing glass layout. Where the panes are unequal, use cumulative T-post centres so the joins can follow them. Each resulting panel must remain within its manufacturing limits.
Measuring Panels
Multiple panels allow shutters to cover wider openings while keeping each panel within its manufacturing limits. Individual panels can be approximately 900 mm wide; the frame adds to the overall assembly width. Check the available layout and hinge limits for the selected size.
What If I Require Multiple Panels but Have Uneven Window Panes?
Unequal panes can be matched with custom T-post positions rather than forcing equal shutter panels across them. Keep every resulting panel within the applicable limits, including the approximate 900 mm individual-panel maximum. Check the opening path of each panel too.
Measuring Custom Panel Widths
Record each T-post centre as a cumulative distance from the same far-left reference. Do not record one panel width after another.
For an inside fit, start at the inside left recess edge. For a face fit over trim, start at the outer left architrave edge. Without trim, start at the finished outside-frame reference, including the specified coverage allowance.
