Impact Window Playbook

Impact windows are laminated, impact-resistant openings that stay in the wall after debris hits the glass. Angi prints professional installation at $700 to $2,875 per window. FEMA describes laminated glazing as two or more glass panes and an interlayer of film. PGT prints large-missile test geometry as a 2X4, 9 pounds, 50 ft./second. South Florida dealer tables print $400–$1,800 installed.

What should a buyer verify first?

Start with the product label and the approval document, not a storefront slogan. National cost guides and Florida dealer blogs publish different dollar bands; keep each band tied to the page that printed it.
