As most of you know, I didn't need the storm windows I put up during the Atlantic Passage, other than peace of mind.
But being my lazy self, I have yet to take them off.
They are 1/2" Lexan and other than where some idiot
got water between the glass and the Lexan on one of them, they are pretty much invisible.
Said idiot will at some point this winter, remove, dry and reinstall.
But the point of this post is that i have discovered that they do an absolute wonderful job of insulating the window so that no condensation forms.
And where they did not totally cover the entire window, lots of condensation does form there,
but I am pleased that it is such a small area on two windows only.
Bottom line is that they do a wonderful job of insulation and now I think I will keep them up year round.
