Building cladding elements and systems

A cladding system configured to be installed on an exterior of a building substrate, the cladding system comprising:

• a plurality of cladding elements, the plurality of cladding elements comprising at least a first cladding element and a second cladding element, each of the first and second cladding elements comprising fiber cement and further comprising:
• a front face configured to face away from the building substrate when each of the first and second cladding elements is secured to the building substrate, wherein the front face comprises a textured pattern;
• a rear face opposite the front face and configured to face toward the building substrate when each of the first and second cladding elements is secured to the building substrate;
• a first mating edge extending between the front and rear faces and extending along a length or height of each of the first and second cladding elements;
• a second mating edge opposite the first mating edge and extending between the front and rear faces and along the length or height of each of the first and second cladding elements, wherein the first mating edge of the first cladding element is configured to mate with the second mating edge of the second cladding element to form a joint groove extending along the length or height of each of the first and second cladding elements;
• and
• a plurality of intermediate grooves recessed from the front face and extending substantially parallel to the first and second mating edges, wherein each of the plurality of intermediate grooves comprises:
• a first curved surface extending from the front face at least partially toward the rear face and having a first radius of curvature;
• a second curved surface connected to the first curved surface and having a second radius of curvature that is smaller than the first radius of curvature of the first curved surface;
• a third curved surface spaced from and opposite to the first curved surface, the third curved surface extending from the front face at least partially toward the rear face and having a third radius of curvature that is substantially equal to the first radius of curvature of the first curved surface;
• a fourth curved surface connected to the third curved surface and having a fourth radius of curvature that is smaller than the third radius of curvature of the third curved surface, wherein the fourth radius of curvature is substantially equal to the second radius of curvature of the second curved surface;
• and
• a planar surface connected to and positioned between the second and fourth curved surfaces, wherein the planar surface is substantially parallel to the front face.
