Key Performance Factors for Windows

What makes a window energy efficient in the Gulf South Two ratings matter most in this climate, U-factor and SHGC, and the low-E package you choose controls both. Reducing conductive heat transfer with a strong U-factor means the AC cycles less. For the Gulf Coast, a low SHGC is critical to limit the sun’s radiant heat. Low-E coatings are not all the same, and the right stack will block infrared heat without darkening the room. Dual-pane, argon-filled units with quality spacers hold their ratings better in the long, hot season. Frames see as much humidity as the glass; vinyl and fiberglass hold shape and seal better than wood here.
