Fiberglass Screen

What do people think about using used fiberglass screen as a layer of cloth? I don't think it could replace cloth, but I would think it could be added just to make things a little stiffer. I have some six foot square scraps which were removed from a screen room. I also have two 4x8' screens on my porch which have some small rips and will require replacement. I'm sure it would be considered garbage by local pros who replace screens. I saw a pile of it on the side of the road on the way to work this week. I would only consider used screen. New screen is about $130 for a 100'x7' roll at the orange box.
