Difference Between Hurricane Impact and Hurricane-Rated Windows

How Impact Windows Are Engineered For Storms

A true impact window is engineered for both pressure and debris resistance, which is why it behaves differently from a standard replacement window with a storm label slapped on it.

When the glass is hit, the laminated makeup is what keeps the pane from scattering and leaving the opening exposed. In real storms, that matters as much as the frame and anchorage.

The frame, glass, hardware, and installation all matter. A good impact window is a system, not just a pane of glass.

How Hurricane-Rated Windows Can Differ From Impact Windows

"Hurricane-rated" is a marketing term more than a single technical category. In practice, it usually means the window has been rated for wind pressure, but that does not always mean it is impact resistant.
