Defenestrate the Headaches

February 27, 2009 · Posted in Uncategorized 

I couldn’t resist the temptation of using the word defenestrate in my title.  So… windows huh?  Have you ever wondered how to compare them?  Wonder no more.  It’s the NFRC to the rescue.  There actually is a coucil that has put together a standard for rating windows.  They are called the National Fenestration Rating Council.  Five categories prove the difference between the good, the bad, and the ones that leak a lot of air.  The categories are:  U-factor, Solar Heat Gain Coefficient, Visible Transmittance, Air Leakage and Condensation Resistance; and all of these categories are displayed on a sticker (if the window has been certified).  Me and my wife wish our 50 year-old windows didn’t leak air and resisted condensation a little better.  Atleast we’ll know what to look for now!
