Board and Batten Siding System

Abstract

A siding system has first and second pieces that are cast from cementitious material. The pieces interconnect and are applied to a structure to create a board and batten pattern. A first board piece has forwardly projecting ridges along each long side. A second piece is a board flanked by two battens that are integral with and an extension of the board. The battens of the second piece interconnect with the ridges on the first piece to create the board and batten pattern. Cast corner pieces finish the corners of the sided structure.

1 . A siding system comprising:
 a first siding piece cast of cementitious material, the first siding piece comprising opposing side edges and opposing ends, a face, and a back, ridges disposed proximate each side edge projecting from on the face of the first siding piece; and   a second siding piece cast of cementitious material, the second siding piece comprising opposing side edges and opposing ends, a face, and a back, hollow battens disposed along each side edge, the battens projecting from the face of the second piece and hollow in the back of the second piece;   wherein the first piece is attached to a structure, a second piece is placed adjacent the first piece so one hollow batten of the second piece interlocks with one projecting ridge of the first piece to create a board and batten pattern.   
     
     
         2 . The siding system of  claim 1 , wherein said projecting ridges are continuous along said each opposing side edge of said first piece. 
     
     
         3 . The siding system of  claim 1 , wherein said projecting ridges are discontinuous along said each opposing side edge of said first piece. 
     
     
         4 . The siding system of  claim 1 , wherein said projecting ridges of said first piece are disposed inside the opposing side edges to create a flange between said projecting ridges and said opposing side edges. 
     
     
         5 . The siding system of  claim 1 , further comprising corner pieces. 
     
     
         6 . The siding system of  claim 5 , wherein said corner pieces comprise opposing side edges and ridges are disposed along each side edge of said corner piece. 
     
     
         7 . A siding system comprising:
 a first siding piece cast of cementitious material, the first siding piece comprising opposing side edges and opposing ends, a face, and a back, ridges disposed inside each side edge projecting from the face of the first siding piece to form a flange between the projecting ridges and the opposing side edges; and   a second siding piece cast of cementitious material, the second siding piece comprising opposing side edges and opposing ends, a face, and a back, hollow battens disposed along each side edge, the battens projecting from the face of the second piece and hollow in the back of the second piece;   wherein the first piece is attached to a structure, a second piece is placed adjacent the first piece so one hollow batten of the second piece interlocks with one projecting ridge of the first piece to create a board and batten pattern.   
     
     
         8 . The siding system of  claim 7 , wherein said projecting ridges are continuous along said each opposing side edge of said first piece. 
     
     
         9 . The siding system of  claim 7 , wherein said projecting ridges are discontinuous along said each opposing side edge of said first piece. 
     
     
         10 . The siding system of  claim 7 , further comprising corner pieces. 
     
     
         11 . The siding system of  claim 10 , wherein said corner pieces comprise opposing side edges and ridges are disposed along each side edge of said corner piece. 
     
     
         12 . A siding piece cast of cementitious material, the siding piece comprising opposing side edges and opposing ends, a face, and a back, hollow battens disposed along each side edge, the battens projecting from the face of the piece and hollow in the back of the piece.
