    You may find Martin Holladay's recent blog on Green Building Advisor
    titled "Rating Windows for Condensation Resistance" helpful.  He
    suggests, "Condensation on your windows is often an early warning
    sign that your interior humidity is too high."<br>

          One guideline that has been implied but not stated in any
          reply I've read is that whatever approach you choose, the
          innermost pane must be the air-tightest to limit condensation.
           The old "rule of thumb" was five times tighter than
          subsequent panes, if there is any leakage.  This allows any
          leakage (drying) to be to the outside.<br>

        <div>Re Bob's note on tight windows, we're now moving into the
          winter heating season.  Our windows are starting to condensate
          at the base on the inside.  Many of you have suggested this is
          the penalty of winter.  Isn't there anything I can do about
          it?  With the windows I have?  Or, are there windows out there
          that don't condensate in the winter?  Are there windows that
          don't leak cold air to the inside from the outside glass per
          Bob's dictum?  Or is this not a matter of tightness, but
          rather of the differences in temperature?<br>
          <br>
          thanks,  Sacie<br>
