Construction panels having an integrated drainage mechanism, and associated assemblies and methods

A building assembly, comprising:

• at least one structural sheathing panel with an integrated drainage mechanism, the panel comprising:
• a structural panel core, and
• a plurality of rows, each row of the plurality of rows comprising raised elements deposited on an external surface of the panel and spaced from one another, each of the raised elements having an elongated, linear profile which has a longitudinal axis, wherein the longitudinal axis of at least one of the raised elements of each row is not parallel to any edge of the panel;
• and
• cladding or insulation installed adjacent the at least one structural sheathing panel, such that the raised elements face the cladding or insulation, and provide an air gap and drainage plane between the external surface of the panel and the cladding or insulation.

A method of making a structural sheathing panel with an integrated drainage mechanism, comprising:

• applying series of material deposits onto an external surface of a structural sheathing panel in a plurality of rows;
• and
• setting the material to form raised elements on the external surface in the plurality of rows, the raised elements each having an elongated, linear profile which has a longitudinal axis and being spaced from one another,
• wherein the longitudinal axis of each of the raised elements is not parallel to any edge of the panel, and
• wherein each of the rows consists of raised elements that are parallel to the other raised elements within that row.
