Hurricane Impact vs. Hurricane-Rated Windows: What’s the Difference?

People often hear "impact windows" and "hurricane-rated windows" as if they are identical, yet the label on the product tells only part of the story.

In Tampa, the product name alone is never enough. The actual approval, test data, and installation details determine whether the window fits the job.

What "Hurricane-Rated" Usually Means

A hurricane-rated window is generally a window that has been tested or approved to perform under severe wind conditions, but that does not automatically mean it can take a direct hit from debris.

If a salesperson uses the term loosely, ask whether the product is impact-rated, what testing it passed, and what documentation comes with it.
