Updated August 2026. Impact windows protect a house by keeping the opening closed after debris hits. Laminated glass can crack and still hold. That protects the building envelope so wind and rain are less likely to pressurize the interior. They are impact-rated, not hurricane-proof.

Quick answer

The tested assembly (glass, frame, anchors) has to match a Florida Product Approval or Miami-Dade NOA for your sizes and design pressures. A crack is not automatically a failure. A blown-out opening is. Statewide Windows & Doors installs these systems in Palm Beach, Broward, and Southwest Florida. Call (561) 816-4010.

What the glass actually does

  • Holds the opening: the interlayer keeps shards together instead of dumping glass into the room.
  • Limits pressurization: a missing window can let wind lift a roof. Keeping the hole closed is the structural point.
  • Needs a real install: CBS waterproofing and fasteners matter as much as the lite. See block waterproofing.

We do not claim nothing gets through, and we do not claim every non-impact house loses its roof.

FAQ

If it cracks, do I need a new window the same day?

After the storm, have the unit inspected. A cracked lite that still holds may be a warranty or replacement item. Do not leave a failed opening open.
