Mounting orientations for projection screens vary. There are different types that are better for certain uses and each type has its own characteristics that make it better suited to certain environments than other mounting orientations. Hanging projection screens are one such mounting method that has some unique characteristics.
Hanging projection screens are mounted on a wall or other secure base. Hanging screens are most likely to be used in situations where the screen is used on a regular basis. This is because the screen is usually difficult to take up and down.
A hanging screen is very convenient for places where it will be used often as it is ready for use at any time. A couple good examples of where hanging screens are best used are in a classroom or church. In both cases, people are going to usually be kept away form the screen and the screen will be used often.
There are two types of hanging screens. One type is permanently mounted, most often to a wall. This screen is attached to a frame and never moves from the ready position. The other type of hanging screen is a retractable screen. This type of screen is also mounted to a wall or other surface, but can be rolled up when not in use. Both types of screens are meant to be used in the same place every time, but retractable screens also allow for the screen to be stored away when not in use.
Hanging projection screen mounting is good for places like classrooms or meeting rooms, where the screen is going to get a lot of use. In places where there are a lot of people who are moving about, a retractable hanging screen may be a better choice than a permanent screen, as being able to store it away will help to protect it from damage.
