After Hurricane IVAN, we had our windows appraised because some "fogged." Later, I was told that one could perform an "ice test" to ascertain the integrity of the seal of double pane windows which has been compromised and they are destined to fail. The test is as follows: Rub an ice cube on the inside pane of the double pane window until one is sure that the temperature has fallen -- usually indicated by frost forming on the glass or definite condensation between swipes with a cloth to wipe off the ice melt. After several swipes to keep the window dry, if condensation forms on the iced area BETWEEN the panes, and cannot be wiped off, it indicates that water has entered the space between the panes since the seal has been compromised. It follows that the window needs to be replaced because fogging is inevitable, but it might take a while.
I have done this with our windows. Many more test “positive: for compromised seals than is evident through frank fogging. I have mixed opinions from window companies. Some have said it’s a very valid test, but they don’t do it. Others have never heard of it.
