When I lived in Brazil, we had window screens, but it was on an affluent area in the coast of Rio. I'm not sure it made things that much better though. You need a lot of discipline to keep those screens shut all the time when you live in a tropical country and go outside all the time.
We just learned that during the summer, around 7pm, it was time to close doors and windows and turn the A/C on.
In England at least you can't easily find them and even if you could your local council would likely not approve the planning permission to install them.
