That's because you now only have a few areas with holes, right? Not
because the holes in the vinyl are bigger than the holes in whatever
you have now?

I'm no judge but the townhouses here were built with windows screening
-- I forget if it is vinyl or aluminum -- the whole width of the
house, front and back, about 4 inches wide.
If you are going to put screening behind it, maybe all you need is the
screening? Not it.
