We used Superscreen, a brand. it is more expensive, but you can have expanses of 120 sf, allowing for less vertical/horizontal members and more wide open views.

Thank you! That's the product we're considering for a similar sized enclosure. I was concerned about it appearing too dark/opaque. I've seen other pictures where it almost looks black, but this photo looks so pleasing. Have you found that your visibility is lessened compared to traditional screens?
