The other day, I was on a mission to seal up some drafts and prevent heat loss.
I noticed that the casement window in the basement was just single pain glass.
I removed the screen and planned on cutting to size a piece of poly-carbonate storm window to replace the screen with.
Before I did this, I scraped away the flaking paint, sanded and prime the surface and then finished it with an exterior latex based paint.
I waited a day for this to dry and then installed the poly window and siliconed in place. Today I checked the window to see if I sealed it up OK and noticed that there is now fogging/moisture sticking to the poly window.
I figured a dead air space would help the R-value of the single pain glass window but, don't want moisture between the pains.
Is this a temporary condition from the paint still curing or should I expect this to be the case all winter long.
For now, I have the casement window open to the inside trying to help the silicon, paint and moisture dry out. I even sprinkled some descicant silica in the window to absorb some of the moisture but, in the long run, I want a moisture free condition.
Did I do something wrong in my efforts to help retain heat and ward out the cold?
