In Phoenix, choosing window glass is not only about how much light you want—it’s also about how much solar heat you want to bring indoors.🏠🌱
That’s where Solar Heat Gain Coefficient, or SHGC, becomes an important number to understand.
A lower SHGC generally means less solar heat enters through the glazing. For homes exposed to intense desert sun, that can be an important consideration alongside U-Factor, glass configuration, and shading strategy.🪟
The key is not simply choosing the lowest number available. The right glazing specification depends on the home’s orientation, climate, window size, and overall design.
So when comparing windows for a Phoenix or Scottsdale project, don’t stop at “double pane.” Ask what the glazing is designed to do.
Good window selection starts with the climate—and the way the space is actually used.
