  • Durable acoustical panel and method of making the same
    Patent number: 6616804
    Abstract: An acoustical panel has a fiberboard which includes a fibrous filler and a base binder, and a nodulated overlay disposed on the fiberboard, wherein the overlay includes nodulated wool and an overlay binder and has a substantially smooth surface. In one embodiment of the present invention, the fibrous filler is mineral wool and the base binder is granular starch. In an another embodiment of the present invention, the nodulated wool is nodulated mineral wool and the overlay binder is cooked pearl cornstarch. A method of making the durable acoustical panel in accordance with the present invention is disclosed. Initially, an aqueous slurry comprising a fibrous filler, a base binder, and water is formed. The aqueous slurry is deposited onto a moving foraminous support wire to form an aqueous felt, thereby creating a continuous process. Thereafter, the aqueous felt is de-watered to form a wet felt.

  • Method of making perforated vinyl film ceiling board
    Patent number: 3954540
    Abstract: A standard fiber composition ceiling board is provided with an outer laminate of plasticized vinyl film. The holes in the film are smaller than the holes in the fiber composition ceiling board. The product is made by laminating the vinyl film to the ceiling board, then perforating the film and the ceiling board with pin punches. The perforations in the board stay at the size at which they are formed, while the holes in the film shrink in size.
