There is provided a board for building with a magnetic layer including the board for building; and the magnetic layer that covers at least a part of a surface of the building board, wherein the magnetic layer includes a magnetic material and an inorganic binder.

A cladding element, for use in a building envelope, comprising a first face, a second face and a plurality of edges. One or more of the plurality of edges includes a mating feature configured to resist moisture passage between cladding elements when the cladding elements are installed on a wall or other structure. The mating features of each cladding element including one or more concave arcuate bevelled edges designed to improve the overall aesthetic appearance of the mating interface between adjacent cladding elements when installed on a wall or other structure.

The mating features of each cladding element including one or more beveled edges designed to improve mating between the cladding elements and the overall aesthetic appearance of the mating interface between adjacent cladding elements when installed on a wall or other structure.

A lap siding product with a unique shiplap joint that spaces abutting pieces of siding correctly from each other without installer measurements. The shiplap joint comprises a bottom element and a top element. A lap siding panel or board has a bottom element shiplap joint at one end, and a top elements shiplap joint at the other end. The corresponding ends of two lap siding panels or boards (i.e., one bottom element and one top element) together form the unique shiplap joint of the present invention. One or more drainage channels or grooves help re-direct water from the joint, and at least one of the channels or grooves also provides a visual element for proper spacing. An engineered “stop” on the underside of the top element also helps space the pieces of siding correctly, without requiring measurement during installation.

A cladding element, for use in a building envelope, comprising a first face, a second face and a plurality of edges. One or more of the plurality of edges includes a mating feature configured to resist moisture passage between cladding elements when the cladding elements are installed on a wall or other structure. The mating features of each cladding element including one or more beveled edges designed to improve mating between the cladding elements and the overall aesthetic appearance of the mating interface between adjacent cladding elements when installed on a wall or other structure.

A building system including a first water resistant layer secured to a building substrate, first and second building articles secured to the first water resistant layer and the building substrate such that sides of the building articles are positioned adjacent one another along an abutment line, and a second water resistant layer secured to portions of the first and second building articles along the abutment line to prevent liquid from traveling past the sides of the building articles to the first water resistant layer and the building substrate. In some embodiments, the building articles are fiber cement building articles. In some embodiments, the building articles include a plurality of integrally formed drainage channels and a plurality of spacer sections disposed between the drainage channels, each of the plurality of drainage channels defining an air gap comprising a liquid flow path.

Methods and systems for form an omnidirectional drainage plane integral to a surface of a fiber cement panel. A felt belt used in a Hatscheck process for forming the fiber cement panel includes a belt adaptation that imprints a panel adaptation on the felt surface of the fiber cement panel. The belt adaptation may span the entire felt belt, or may be configured only on a portion, or portions, thereof.

A method for producing a building material includes a first step of applying an undercoat paint onto a surface of an inorganic base material, curing the undercoat paint, and polishing the undercoat paint; and a second step of applying an enamel paint onto the undercoat paint and curing the enamel paint. The undercoat paint contains an undercoat-forming material and a filler. The enamel paint contains an enamel-forming material and a pigment. The enamel-forming material is a solvent-based resin. A content of the filler in the undercoat paint is 40% to 70% by mass in terms of solid content. A content of the pigment in the enamel paint is 1% to 50% by mass in terms of solid content.

A cladding element, for use in a building envelope, comprising a first face, a second face and a plurality of edges. One or more of the plurality of edges includes a mating feature configured to resist moisture passage between cladding elements when the cladding elements are installed on a wall or other structure. The cladding element can include one or more joint features to improve mating between the cladding elements, reduce labor costs, and facilitate moisture drainage from the cladding elements.

A cladding system configured to be installed on a building substrate includes a plurality of fiber cement cladding elements and at least one trim element. The plurality of fiber cement cladding elements includes at least a first and second cladding element, each having a front face with a textured pattern, a rear face, first and second mating edges configured to allow mating between the first and second cladding elements, and a plurality of intermediate grooves recessed from the front face. The at least one trim element includes one or more channels configured to receive a portion of at least one of the first and second cladding elements. Each of the plurality of grooves includes a first curved surface, a second curved surface, a third curved surface, a fourth curved surface, and a planar surface positioned between the second and fourth curved surfaces and substantially parallel to the front face.
