This one is a bit complex. Because there are a variety of different screens, the prices of these screens also tend to vary wildly. Typically, inflatable outdoor screens tend to be the most expensive. A typical eighteen feet back-projection inflatable screen can cost as much as a luxury car. However, you don’t need them unless you are operating an outdoor cinema. On the other hand, you will be able to find a really cheap foldable projection screen for around fifty dirhams. A typical portable screen that is suitable for classrooms will cost between two or three hundred dirhams.
