How does laminated glass fail and still hold?

FEMA’s wall-openings fact sheet treats impact-resistant glazing as a retrofit option for window openings. Laminated systems use two or more glass panes and an interlayer of film laminated into the assembly. The glass may break; the interlayer is what keeps the opening from becoming a hole.

FEMA P-2181 Fact Sheet 3.2 prints laminated glazing systems as “two or more glass panes and an interlayer of film laminated into the assembly.” The glass panes may be broken by wind-borne debris, but the interlayer will remain intact to prevent wind and wind-driven rain entry.

How is this different from the Florida dealer band?

Keep Angi and Florida dealer dollars on separate rows. A South Florida installer guide prints $400–$1,800 per window installed and says most homeowners pay $800–$1,400 per window. That is a different geography and a different publisher than Angi.
