An insulation board assembly includes an insulation board body that has a front face, a back face, a top edge, and a bottom edge. The back face has a drainage channel extending from the top edge to the bottom edge. A drainage insert is positioned in the drainage channel proximate the bottom edge of the insulation board body. The drainage insert has a front face, a top edge, a bottom edge, and two side edges, and an insert height measured between the top edge and the bottom edge of the drainage insert. The drainage insert defines at least one interior drainage passage extending from the top edge of the drainage insert to the bottom edge of the drainage insert. A channel height of the drainage channel is preferably at least twice the insert height.

A composite wood prefabricated wall panel configured for reduced moisture absorption includes a composite wood panel body, one or more connection components, and a priming layer. The composite wood panel body includes a front face, a rear face, and at least one edge. The one or more connection components are affixed to the rear face or the at least one edge, and the one or more connection components are configured to secure the composite wood prefabricated wall panel to one or more structural members of a prefabricated wall system. The priming layer is disposed over one or more surfaces of the composite wood panel body.
