Also available for purchase are screen wall panels for your structure. These can be popped in place or for behind the acrylic window panels; they are the same size. The acrylic window panels each slide on their own individual rails, but can also be removed. If you would like to configure an all screen wall, the gazebos up to 10 x 10 in size use 3 panels per wall (12 total panels), while gazebos over 10 x 10 size use 4 panels per wall (16 total panels).
