U-Factor and SHGC in Window Replacement

Why These Ratings are Crucial

  • The U-Factor is the rate of heat flow through the window - the lower the U-Factor in your window replacement, the less energy is needed to heat a home and better the window insulates.

 

  • The SHGC is the solar heat penetrating through the window - the lower the SHGC, the less solar heat will penetrate and the more you conserve on air-conditioning.
