High u-factor
WebMay 3, 2013 · U-value (also known as U-factor) is a measure of heat transfer (heat gain or loss through glass), while R-value is a measure of heat resistance. U-value is not a material rating; it is a calculation of the conduction properties of various materials used in the construction of windows, doors and skylights. WebHigher bills indicate the importance windows with a lower U-factor for added energy efficiency. In mixed climates in the South and central regions that use both heating and cooling, the U-factor should be less than or …
