Projection screen material can be divided into a number of varieties. The main factor to be placed under consideration is the ability of a particular material to reflect a certain amount of light. Matte white, pearlescent, silver and glass beads are the most common ones being used nowadays. These four types can be used to produce projection surfaces of varying quality and performance. Of the four, pearlescent and silver are the ones being commonly used because they reflect approximately 15-30% of the light that is placed upon them.

This results in images that are either dull or too bright.

Permanent screens are ones that are installed permanently upon a wall and cannot be removed easily.
