What is a U-Value?
U-Value measures how well a product prevents heat from escaping a home or building. U-Value ratings generally fall between .20 and 1.20. The lower the U-Value the better a product is at keeping heat in. U-Value is particularly important for homes located in cool, northern climates and during the winter heating season.
What is Solar Heat Gain Coefficient?
Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from entering a home or building, whether directly transmitted or absorbed and subsequently released inward.

Blocking solar heat gain is particularly important for homes located in warm, southern climates and during the summer cooling season.
