A customizable glass wall system is disclosed. The system comprises at least two glazed, transparent panes mounted to a frame, creating an internal space less than approximately five inches thick. At least one upper roller is mounted to an upper portion of the frame, preferably on a removable headboard, and at least one lower roller is mounted to a lower portion of the frame, preferably to a removable tailboard. At least one partitioned film is attached to the upper and lower rollers. The partitioned film has partitions with varied properties and functions, ranging from thermal insulation to decoration, which can be selectively positioned behind the transparent panes by rotating the partitioned film by means of the rollers until a selected partition of film is displayed. The system can be automated based on time, weather, amount of sunlight, or user preference, and it may include window coverings or solar cells.
