ABSTRACT:
This invention consists of a flame-retardant, coated fabric material for use in the manufacture of rolling-door panels, blades, or leaves. It is particularly designed for use in the kind of high-speed, light-weight doors currently found in the garages and vehicle bays of warehouses, factories, and other industrial facilities. In addition to being much lighter than the metal doors being replaced, the material of the present invention has to its further advantage a flame-retardancy not present in earlier fabric doors.
