My neighbor has had a sweating problem for about 6 weeks. I didn't think I had such a problem, but today with weather in the 20's and 30's, our windows are sweating galore. We are mainly using our unvented fireplace, with central heat kicking on very little. Anybody know why our thermal windows are sweating? Appreciate an answer. VB
P.S. We have a hip roof, 1260 sq. ft. home.
