We came across a new product from RP Visuals (www.rpvisuals.com) that may be the answer to your screen problems. The bendable ULTRAFLEX projection screen ships in a cylinder as small as 40-inches in diameter. Once on-site, it is unrolled, tensioned and installed. The largest installed size available is 96-inches high x 300-inches long.
The small shipping size allows for installation in tight spaces, and the flexible screen works well on curved (concave or convex), contoured (S) and cylindrical applications. The flexible screen is perfect as a replacement for a damaged glass screen that cannot be replaced due to access limitations. The screens are appropriate for both front and rear projection.
