Mike asked for some information about the wet wall I built so here are a few photos taken during the construction process. I started with a modular kit but had to modify it in a gazillion ways to make it work the way I wanted it to in this setting. For example ... the shutter motors are supposed to be mounted below the shutters & pull them open (downward) with a chain. That wouldn't work for my project so I mounted them above & built an actuator setup instead. Anyway ... the system works beautifully ... no regrets except for cost.
