The Role of Low-E Glass in Hot, Humid Climates

Why Humid Heat Is Hard On Windows

Windows in hot, muggy weather are dealing with two problems at once. Solar heat keeps pounding the glass, and high indoor-outdoor humidity makes it harder for the home to stay comfortable. If the window system is not doing much to resist either one, the AC ends up carrying the load.
