Regarding Fiberglass mesh screens, I agree with the looks and cost but did you know that grasshoppers have the ability to dissolve the mesh material? I'm currently experiencing this now because my property backs up to a farm field. We are watching our screens disappear a little bit at a time.
Answer:
I'd replace with vinyl mesh. I didn't know there was a problem with grass hoppers but its a handy bit of trivia to paly with. Thanx.
