Understanding U-Factor and SHGC

  • U-Factor: U-Factor measures a window’s resistance to heat transfer. A lower U-Factor indicates greater insulation capability, meaning less heat loss during cold weather and reduced energy consumption for heating your home.

  • Solar Heat Gain Coefficient (SHGC): SHGC measures a window’s ability to block solar heat from entering your home. A lower SHGC means the window effectively prevents solar heat gain, reducing the need for air conditioning and cooling costs during hot weather.


Anlin windows and patio doors are tested and certified by the National Fenestration Rating Council (NFRC), the American Architectural Manufactures Association (AAMA), and Energy Star. Each certification assures homeowners that our windows and patio doors are manufactured to the highest quality and energy standards.
