Abstract
A method for directing a stream of bulk fibers while simultaneously spraying a solution of high temperature resistant tacky binder material into the stream of fibers. A layer of high temperature insulating fibers on a furnace, kiln, or other surface to be thermally protected may thus be formed. The layer of binder coated fibers is then cured to a monolithic layer.
