Double Hung Impact Windows

Double hung impact windows represent a significant upgrade over single hung models by allowing both the upper and lower sashes to slide independently. This dual-operation design enables a natural ventilation technique known as stack ventilation: by opening the bottom sash to draw in cooler air while simultaneously opening the top sash to release warm air rising inside, you create a continuous airflow cycle that can reduce your reliance on air conditioning during South Florida's cooler months and pleasant evenings.

One of the most appreciated features of double hung impact windows is the tilt-in sash mechanism. With a simple release of the tilt latches, both the upper and lower sashes pivot inward, allowing you to clean the exterior glass from the comfort and safety of your home interior. This is especially valuable for second-story and third-story windows, where exterior cleaning would otherwise require ladders or professional window washers. In South Florida's coastal environment, where salt spray and mineral deposits can cloud glass quickly, the ability to clean your windows effortlessly is a genuine everyday benefit.

From a hurricane protection standpoint, double hung impact windows are every bit as robust as any other style. The laminated impact glass meets Miami-Dade County's rigorous testing standards for both large missile impact and cyclic wind pressure. The multi-point locking system engages at multiple points along the sash rail, distributing wind load forces evenly across the frame and maintaining a watertight seal even under extreme conditions. These windows are engineered specifically for the High-Velocity Hurricane Zone and comply with all current Florida Building Code requirements.

Double hung impact windows are available in a wide range of frame materials, colors, and finishes. Aluminum frames provide strength and slim sightlines popular in modern designs, while vinyl frames offer superior thermal performance and virtually zero maintenance. Decorative grid options including colonial, prairie, and diamond patterns allow you to match the specific architectural character of your home. With custom sizing available, double hung windows fit openings from compact bathroom windows to generous living room installations, making them one of the most versatile choices for whole-home hurricane protection in South Florida.
