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>
