What Window shape Is Used Most Often In Hurricane-Prone Areas?

Casement windows are the most commonly used window style in hurricane-prone areas because they offer the strongest wind resistance and sealing.

In regions frequently hit by hurricanes, like coastal Florida, casement windows are favored because of how well they function and perform under pressure. Their side-hinged design allows them to close tightly and lock securely along the entire frame. When high winds push against the glass, the wind pressure actually forces the window more tightly improving the seal rather than weakening it. This makes them less likely to break or leak during a storm.

This window style is also practical for meeting strict building codes in High-Velocity Hurricane Zones, where windows must pass large and small missile impact tests. While other window styles like sliding or double-hung windows are used in some homes, they are generally more vulnerable because of looser seals and more moving parts.

So, when choosing window styles for hurricane protection, casement windows are the most commonly installed because they combine structural strength, strong closure, and tested reliability in high-wind conditions.
