[Greenbuilding] Condensation on Windows

[John E. Beeson]

Bob, got any good _external_ movable insulation examples that are simple
and cheap?


From: "Bob Korves" <bkorves at winfirst.com>

To stop condensation on the inside of windows on cold nights it is more 
effective if movable insulation is on the _outside_ of the glass and
fits 
fairly tightly.  This helps to _increase_ the temperature of the glass 
raising the glass temperature above the dewpoint and eliminating 
condensation.  Putting insulation on the inside of the glass helps
_reduce_ 
the temperature of the glass, increasing condensation unless the
moisture is 
tightly sealed away, which is quite difficult to accomplish.
