Minimum Profile Inertia to correct bended plate

Hi Everyone,

I'm having some troubles solving a problem. It might be an obvious answer, but I'm kind of stuck.
The problem consists on a glass sheet that came out bended due to thermal treatment in aprox. 4/5 mm. This deformation doesn't allow a mosquito net to slide behind it.

As the panel is simply supported at the top and bottom, I need to find the minimum inertia for some lateral edge beams to straight the panel up to a miminum of 1/2 mm.

Can someone please help me on how to properly approach this situation?
I tried to apply a Line Load in the center of the panel that would cause the 4/5 mm deformation, and then find the inertia from there. I did this in a FEM software but this assume that the plate is flat.

y=2 mm , but I doubt that you can straighten glass in this way
