Abstract
A plurality of rainscreen elements or features that are applied to the front or outer face of a structural panel or the weather resistant barrier layer on the structural panel. When an exterior cladding or sheathing product is installed over the structural panel, the rainscreen elements or features provide built-in water flow gaps or channels to facilitate and increase water drainage off the face of the structural panel, thereby minimizing water storage in the space between the structural panel and the outer cladding/sheathing. The rainscreen features are incorporated into the structural panel in-line or during the manufacturing process, and do not require any further work during assembly or construction on-site.
Claims13
A pre-manufactured integrated structural panel with integrated rainscreen, comprising:
- a base layer with an inner surface and an outer surface, and a first edge and a second edge, wherein the second edge is orthogonal to the second edge;
- at least one water resistant layer integrated with the base layer and substantially coating the outer surface;
- and
- a plurality of rainscreen features integrated with the at least one water resistant layer and arranged on the water resistant layer opposite the base layer, wherein said plurality of rainscreen features comprise
- a first type of raised linear element with a length and a width, wherein the length is greater than the width, with the length of the first type of raised linear element arranged parallel to the first edge of the base layer in a first orientation, and
- a second type of raised linear element with a length and a width, wherein the length is greater than the width, with the length of the second type of raised linear element arranged parallel to the second edge of the base layer in a second orientation;
- wherein the first orientation is orthogonal to the second orientation;
- and
- further wherein the plurality of rainscreen features create a plurality of fixed gaps or fluid channels therebetween.
