I remember reading about taking a U factor by square foot ( of lets say a wall material or window) in one of my books but CANNOT refind it to save my life ( go figure) and search results on the internet and this forum have turned nothing up.

Can anyone shed some light on this or did I just make this up?

  I believe this information is in the ARE demonstration exam resources. It has a u-factor formula that accounts for opaque walls and windows. Hope this helps.
