The Elite Screens Insta-RP Rear Projection Screen Film is an optical roll film that can be applied to a wide variety of surfaces including store windows, resorts, restaurants and nightclubs. The self-adhesive surface is easy to use and is a more-than-viable option when a traditional rear screen installation is not feasible. The surface generates a bright 2.2 Gain rating so your image will be easily seen. The diffused nature of the film produces a diffused viewing angle of 180deg. making it easily seen from almost anywhere in the venue. In addition, the Insta-RP is easy to clean and maintain.
