How to Tell if Your Windows Are Hurricane Rated

Start With The Label, Not The Glass Thickness

The surest answer usually starts with the label on the glass or frame, because hurricane-rated windows are documented, not guessed at.

A real impact unit is usually tied to a product approval number, test report, or installation paperwork that shows it was evaluated for wind pressure and missile impact.

If the label is gone, look for the paperwork from the permit file, the contractor invoice, or the manufacturer’s specification sheet.

An experienced window replacement company can confirm the cause with a quick inspection.

Weight and appearance can be misleading, because some non-rated windows look substantial but were never tested for storm impact.
