Because my house has shutters, I can't use regular screens because then I can't reach through to close the shutters. Instead, we use curtains of netting stretched between spring-loaded curtain rods. The panels meet in the middle and it is easy to reach through to close a shutter.

All the spring-loaded rods I have found are ferrous metal and they rust. Our windows are open 24/7 and we only close them if it rains really hard. The rods often get a little water on them and rust.
