Abstract
A sheathing material includes a layer of ceramic paper to help prevent the burning of the sheathing during a fire. The material may include insulation disposed between the ceramic paper and the substrate to further reduce damage to the substrate, and may include a thin layer of wood or paper placed over the ceramic paper to protect the ceramic paper and to allow the sheathing to be used in a manner similar to that of a conventional sheathing material.
Claims17
A preformed construction sheathing material comprising:
- a generally planar and continuous sheet of gypsum board having a length and a width and having a first side and a second side and a thickness disposed between the first side and the second side;
- and
- a layer of ceramic fiber material affixed directly to the first side of the sheet of gypsum board to cover substantially all of the first side thereof;
- wherein substantially all of the second side of the sheet of gypsum board is exposed and forms a second exterior surface of the sheathing material opposite the first exterior surface of the sheathing material;
- wherein the sheathing material is attached to a building as wall sheathing or ceiling sheathing, such that the second side of the sheet of gypsum board is attached to the building, such that the first side of the sheet of gypsum board faces away from the surface of the building to which the second side of the sheet of gypsum board is attached, and such that the sheet of gypsum board is disposed between the layer of ceramic fiber material and the building such that the layer of ceramic fiber material covers the sheet of gypsum board.

A preformed sheet material for use in construction comprising:
- a generally planar sheet of gypsum board having a length and a width and having a first side and a second side and a thickness between the first side and the second side;
- and
- a layer of ceramic fiber material having a first face and a second face, wherein the first face is attached to the first side of the generally planar sheet of gypsum board such that the ceramic fiber material covers substantially all of the first side of the sheet of gypsum board;
- wherein substantially all of the second side of the sheet of gypsum board is exposed and forms a first exterior surface of the sheathing material;
- and
- wherein the second face of the layer of ceramic fiber material is exposed and forms a second exterior surface of the sheathing material which is opposite the first exterior surface of the sheathing material.

A preformed sheet material for use in construction comprising:
- a generally planar sheet of gypsum board having a length and a width, a first side and an opposed second side, and a thickness between the first side and the second side;
- a thin layer of ceramic fiber fire barrier sheet material which has a first side and a second side, wherein the first side of the layer of ceramic fiber fire barrier material is attached to the first side of the sheet of gypsum board to cover substantially all of the first side of the sheet of gypsum board;
- an outer paper layer attached to the second side of the layer of ceramic fiber fire barrier material to cover substantially all of the layer of ceramic fiber fire barrier material;
- wherein substantially all of the second side of the sheet of gypsum board is exposed and forms a first exterior surface of the preformed sheet material;
- and
- wherein the outer paper layer forms a second exterior surface of the sheathing material disposed opposite the first exterior surface of the sheathing material.
