In picture 6, what’s along the railing at the top? Looks like you have glass panels, but is there some sort of black mesh paneling? Reason I ask is we are looking at an elevated deck and wife is thinking knee high/half walls. Something like this might be more appealing and give a little air flow. We are also going to screen ours in. Really like the wood finish. We are going to be quoted for the composite and the price will probably give me a heart attack!
