Specification notes

This record covers the standard laminated safety-glass FCM configuration. Impact, white laminated, triple-pane, and tempered options are separate configurations and are not projected onto this record.
The source proves two panes but does not state that either pane is tempered. No tempered-pane count is inferred.
FCM is fixed. Do not use this record to answer an operable-skylight mesh requirement.
Confirm size, curb, slope, flashing kit, glazing code, installation, and local approval for the ordered unit.
