Disclosed herein is a trough-edge building panel used in the fabrication of panelized wall systems with elastomeric joints that are resistant to cracking. The panels are preferably fiber cement. The front surface of each panel has a trough adjacent to an edge of the panel. Panels are fastened to a frame with the trough-edges adjacent to each other. A joint tape is applied to the seam between the panels such that the edges of the joint tape fall within the troughs of the adjacent panels. The wall is then finished with an elastomeric finish. Also disclosed is a method of manufacturing the trough-edge panels.

What is claimed is: 1. A trough-edge building panel comprising: a building panel comprising a front surface, a back surface, and a plurality of edges and a plurality of troughs on the front surface of the panel, each trough on the front surface of the panel extending along an edge of the panel, whe
What is claimed is: 1. A trough-edge building panel comprising: a building panel comprising a front surface, a back surface, and a plurality of edges and a plurality of troughs on the front surface of the panel, each trough on the front surface of the panel extending along an edge of the panel, wherein independently for each trough, the trough is spaced inwardly from the edge of the panel by a trough edge offset, the trough is sized and configured to accept an edge of a backing material applied over a seam between adjacent panels, and the trough comprises a wall and a floor, wherein a side of the trough proximate to the edge of the panel forms the wall, wherein the height of the wall is a trough depth, the floor of the trough is lower than a surface of the panel between the wall of the trough and the edge of the panel, and the width of the floor is a trough width, wherein the building panel substantially comprises a material selected from the group consisting of inorganic substrates, fiber-reinforced inorganic substrates, aluminum, cement composites, wood, plywood, oriented strand board, wood composites, and gypsum. 2. The trough-edge panel of claim 1, wherein the panel is fiber cement. 3. The trough-edge panel of claim 2, wherein the panel is about 4' by about 8'. 4. The trough-edge panel of claim 2, wherein the panel is from about 3/16" to about 2" thick. 5. The trough-edge panel of claim 2, wherein for at least one trough, the trough edge offset is from about 쩍" to about 3", the trough depth is from about 0.005" to about 0.25", and the trough width is from about ⅛" to about 2". 6. The trough-edge panel of claim 2, further comprising a surface offset depth of from 0" to about 0.1". 7. The trough-edge panel of claim 1, wherein the troughs are formed by embossing, using a plate press, using a profiled accumulator roll in the Hatschek process, or by post-cure machining. 8. The trough-edge panel of claim 1, comprising two troughs on opposite edges of the building panel. 9. A method of fabricating a trough-edge building panel comprising: creating a plurality of troughs on the front surface of a building panel, each trough on the front surface of the panel extending along an edge of a panel, wherein independently for each trough, the trough is spaced inwardly from the edge of the panel by a trough edge offset, the trough is sized and configured to accept an edge of a backing material applied over a seam between adjacent panels, and the trough comprises a wall and a floor, wherein the side of the trough proximate to the edge of the panel forms the wall, wherein the height of the wall is a trough depth, the floor of the trough is lower than the surface of the panel between the wall of the trough and the edge of the panel, and the width of the floor is a trough width, wherein the building panel substantially comprises a material selected from the group consisting of inorganic substrates, fiber-reinforced inorganic substrates, aluminum, cement composites, wood, plywood, oriented strand board, wood composites, and gypsum. 10. The method of claim 9, wherein the panel is fiber cement. 11. The method of claim 10, wherein the panel is about 4' by about 8'. 12. The method of claim 10, wherein the panel is from about 3/16" to about 2" thick. 13. The method of claim 10, wherein for at least one trough, the trough edge offset is from about 쩍" to about 3", the trough depth is from about 0.005" to about 0.25", and the trough width is from about ⅛" to about 2". 14. The method of claim 10, further comprising a surface offset depth of from 0" to about 0.1". 15. The method of claim 9, wherein the troughs are formed by embossing, using a plate press, using a profiled accumulator roll in the Hatschek process, or by post-cure machining. 16. The method of claim 9, wherein the trough-edge panel comprises two troughs on opposite edges of the building panel.
