Casement vs Double-Hung Windows for Florida Hurricane Zones

How Each Window Style Handles Wind Pressure

The big difference between casement and double-hung windows is not just how they look, it is how they resist wind and water when a storm pushes hard against the house.

A casement window opens with a hinge and crank, and when it shuts, the sash pulls snug against the weatherstripping and frame.

Double-hung windows use two vertical sashes that move past each other, which is familiar, practical, and common in older Florida neighborhoods.
