Aluminum vs. Vinyl Window Frames in South Florida: Which Material Performs Better?

Many national window companies promote vinyl as the superior choice because of its insulation properties and lower cost. However, South Florida presents a very different environment than northern states where many of those recommendations originate. Between year-round UV exposure, extreme summer temperatures, hurricane-force winds, salt air, and strict building code requirements, the performance demands placed on windows in South Florida are unlike those in most parts of the country.

The Answer Isn't Just Energy Efficiency

The right choice comes down to structural integrity, long-term durability, hurricane protection, and maintaining a watertight seal for decades. For most South Florida homes, architectural-grade aluminum impact window frames remain the preferred structural solution for extreme wind-load resistance and long-term durability.
