This week we have our second mini lesson on windows.  Last week we went over the different window styles.  If you don’t know the difference between a single hung and a double hung window or what a casement window is, take a listen to last week’s show, episode 41. 

Today we’ll learn about the energy efficiency of windows.   A window's energy efficiency is dependent upon all of its components—the window frame, the glazing and the coatings.  We’ll talk specifically about each of those components, including the different materials used for the frames, double and triple glazed windows and low E windows.
