I'll try to remeber to take a photo of the doors I have on my boat. I may even have a web able photo............ i know where that is at, I'll modify this post if it is where I think it is. Mine are smoke plexiglass. They would have a bit more ventilation than you have, but reality is, those will work.
My slats are teak plywood veneer, they need varish yearly. I'm going to try and build the new ones of solid teak or iron wook my sons had left over from building a dock.
Found it, not the best photo, but will work, bottom right of page 2 of link, or page 14 of the actual magazine article. I'll get a better one if it looks appealing for version 2 if you ever get that far........
