Like roller blinds, black-out blinds consist of a fabric that is wrapped around a tube. This fabric is made of light-tight material, which can be completely darkened and rolled up as required. Because of the side rails with connection to the wall a complete light termination results. Black-out blinds from erfal are mainly used in industrial buildings with large glass façades as well as in public facilities such as event halls or schools.
