Polycarbonate privacy screen for balcony, solid or multi-wall?

I am building a privacy screen on one side of my balcony (main reason is to block visual contact with the short term rental place next to us). I have a couple of metal posts installed for this purpose. The size of the screen is 110cm (3.5 feet) wide by 210cm (7 feet) high. I bought a 5mm solid polycarbonate panel, drilled holes on the sides and attached to the mounting tabs I have on the metal posts. I found this panel to be a bit to flexible/wobbly at this size, so looking for alternatives for the remaining 3 same sized spaces. Going thicker is no good as this panel is already quite heavy. I found some multi-wall polycarbonate panels, 16mm thick, one type with X shaped cross section + middle layer, and another with 5-6 parallel layers inside. They are about half the weight of the panel I have. Since I am ordering online, I can't gauge how they compare to the 5mm solid panel. Could anyone help me understand if the multi-wall panels could be less flexible and more likely to stand up on their own? (And if so which cross section to get? what to do about exposed sides?) Thanks in advance! submitted by /u/Winter-Strike8903 [link] [comments]
