About Ratings - Heat Gain & Loss

Windows, doors, skylights can gain and lose heat through:

  • Direct conduction through the glass or glazing, frame, and/or door
  • The radiation of heat into a house (typically from the sun) and out of a house from room temperature objects, such as people, furniture, and interior walls
  • Air leakage through and around them

These properties can be measured and rated according to the following energy performance characteristics:

U-factor is an indicator for how insulating your overall window is. The lower the U-factor number, the more energy-efficient the window/door is. Especially important in colder climates.

Solar Heat Gain Coefficient (SHGC) is the amount of heat the window absorbs and transmits to the inside of your house. The lower the SHGC, the less solar heat it transmits and the greater its shading ability. A product with a high SHGC rating is more effective at collecting solar heat during cooling loads during the summer by blocking heat gain from the sun. Your home’s climate, orientation, and external shading will determine the optimal SHGC for a particular window, door, or skylight.

Air leakage is how much air is leaking into your house through the window when there is a pressure difference. Typically, drafty homes have high air leakage windows and doors. A product with a low air leakage rating is tighter sealing than one with a high air leakage rating.

 

Sunlight Transmittance

The ability of glazing in a window, door, or skylight to transmit sunlight into a home can be measured and rated according to the following energy performance characteristics:

Visible Transmittance (VT) is how much visible light is going into your house through your window and door. A product with a higher VT transmits more visible light. VT is expressed as a number between 0 and 1. The VT you need for a window, door, or skylight should be determined by your home’s daylighting requirements and/or whether you need to reduce interior glare in a space.
