Hello everyone! I'm new to the forum and need some window help.
The problem is that my neighbor's double pane Pella windows are concave and the resulting concentrated reflection is melting my vinyl siding.
The same thing is happening to my other neighbor's siding from the concave Pella windows installed in my home. They've only been in their house for a year and have replaced their siding twice, and it has already melted a third time!
I'm not sure why the windows are so concave, but if I place a 2' straight edge across the window, there is an 1/8" gap from the straight edge to the glass in the middle. Over the full length of the window the gap is even greater.
I've tried working with Pella to find a solution and they have not been helpful at all.
I think that the least expensive solution to this problem is to install screens on the outside of the concave Pella windows to reduce the amount of energy reflected onto the siding. The problem is that these are single hung windows and are not designed for a screen on the upper part of the window.
Is there a good way to attach a screen on the outside of the single hung windows?
Here are some photos of the problem...
