Choosing Energy-Efficient Windows for Louisiana’s Humid Climate

What Louisiana's Humid Climate Does To Windows

The window that works in a mild, dry market is not always the right answer for Louisiana's humidity, heat, and long cooling season. High humidity, UV exposure, and constant AC use all change how a window should be built and specified.
