I bought a 40-year-old house last year. The previous owner had put new windows through most of the house. In some rooms, they are Andersen. In others Simonton (I never heard of them).
The Andersen windows are tight and warm. Our couch is in front of a
10'x5' bank of Andersen windows and I can sit with my arm on the back of the couch and not feel a difference in temperature. The Simonton windows are cold. I don't see the blinds move even in heavy winds but standing in front of them, I feel cold air.Do Simonton windows suck or are they poorly installed? If I pulled off the frame and put some Great Stuff around the window, might it seal it better or is it the window that is failing?
