Confused With All Those Window Terms?

Thursday, May 26, 2011

If you’re shopping for windows or doors you’ve probable run across some terms that you are not familiar with.  Everything from R-Values and U-Values to solar heat gain coefficients.  These terms are great to know when it comes time to do window replacement, so we here at FAS Windows and Doors are going to share our knowledge with you.  

R-Value- The capacity of an insulating material to resist heat flow. The higher the R-value, the greater the insulating power
U-Value- a measure of the heat transmission through a building part (as a wall or window) or a given thickness of a material (as insulation) with lower numbers indicating better insulating properties
Solar Heat Gain Coefficients- The percentage of solar heat that is absorbed vs. reflected when it contacts a window
ENERGY STAR label- Energy Star is an international standard for energy efficient consumer products. It was first created as a United States government program by the Clinton Administration in 1992.
