Replacing double-paned window glass
Old window is Willmar Window uPVC, 70/32, installed horizontally in 2001. The seal failed in 2016 on the lower left hand side.
We replaced only the window glass in the summer of 2017. Synergy Solarban 70XL
After a recent winter storm, the frame of the Willmar seems not to support the new window glass.
The base of the new window (at the same place where the first window seal failed), made a scrapping, metallic noise during the storm. Then the top left corner of the window made a tapping sound and I could see that it was moving back and forth. I applied duct tape to frame and window at these locations to minimize the movement.
The bottom corners of the glass are secure to the frame. However the frame is bowed out about 1/8 inch. I should mention that below this window are two small windows, the left one is stationary and the right one slides.
I’d like your opinion. Is my problem the glass or the window frame? Or the installation.
