	The U-Factor is a standard industry measurement that rates how well a window product prevents heat from escaping. The rate of heat loss is expressed in terms of the U-factor (U-value) of the window's assembly. These ratings generally fall between 0.20 and 1.20, with a lower U-value offering greater resistance to heat flow and better insulating value.

	The solar heat gain coefficient (SHGC) measures a product's ability to block heat caused by sunlight. The SHGC is the fraction of solar radiation which is both directly transmitted and absorbed through a window and which is subsequently released inward. SHGC is indicated as a number between 0 and 1. Lower SHGC ratings transmit less solar heat into the house. Homeowners in different climates will look for differing SHGCs, based on the needs of their particular climate.

−	==== Condensation Resistance ====	+	=== Condensation Resistance ===
	Condensation Resistance (CR) measures the capacity of a window's frame, weatherstripping, spacer and glazing to resist the formation of condensation on the interior surface of the window. Higher CR ratings indicate that a window is more successful in resisting condensation formation. The rating is not meant to predict condensation, but rather to compare the various window products to assess their potential for condensation formation. CR is indicated as a number between 1 and 100.
