Vinyl vs. Aluminum Impact Window Frames for Tampa Humidity

How Tampa's Humid Climate Affects Impact Window Frames

In Tampa, the frame choice matters almost as much as the glass package.

Tampa spends long stretches with warm, moist air, and that steady moisture exposure puts pressure on every part of a window assembly.
