    <font size="+1">  It is a small difference, basically negligible.  I
      switched a recent project I did with aluminum spacers to insulated
      in the windows only.  The LV-D report showed no difference, that
      could be because it reports the window U-value.  The LS-C report
      showed a small difference in the Window Glass + Frame, 19.500
      kBTU/h for the aluminum, </font><font size="+1">out of a building
      total 194.197 </font><font size="+1">kBTU/h,</font><font
      size="+1"> 19.413 kBTU/h for the insulated, total 194.109 </font><font
      size="+1">kBTU/h.<br>
        The building had 173 SF of windows in 14,492 SF of wall and 768
      SF of skylights in 7,616 SF of roof, a small percentage.  Also,
      most of the windows were 2'W x 5'H, 10 SF, if the edge effect is
      1" around the frame that is 1.15 SF, 11%, or 19 SF of 173 SF glass
      in 14,492 sf of wall.  If your edge effect is R-1 in aluminum and
      R-3 in insulated in a R-20 wall it becomes a very minor heat
      loss.  In an all glass building it would be the nearly the same
      except if you spent some money on glass you might have 14,492 SF
      at R-4.  The edge effect would still only apply to 19 SF.<br>
        The main effect as I mentioned earlier is to allow higher
      humidity levels in the winter in a cold climate without damaging
      surfaces below the window with condensation.  It shows that
      windows suck when it comes to insulating, edge effect or not. 
      Residentially it has a big effect, by spending an extra $12 on a
      $400 window you get an insulated spacer and argon fill, taking
      your glass from R-2 to R-4.2 but the wood frame will last 20 years
      instead of 5 or 8 because the condensation won't rot out the
      bottom of the frame.  Installation is more important, if you have
      a 1/16" gap around the window frame you just put in a R-4 window
      and a 3.24" square hole in your R-20 wall.<br>
