When the glass panels are open, what do you use to stop someone from falling off the porch? We have the same situation. We looked at Lumon's screen system but did not like it. We looked at other screen systems that rise and lower with a remote and have a strength such that you cannot push through. It is a tough screen material but it is also very heavy and not good for viewing through. And, expensive. We talked about trying to invent a handrail that would lower when the windows were closed and pulled up in place when the glass panels are open. Something similar to the side of crib. Just a though at this time.
