Abstract
The disclosure provides example drainage channels, drainage systems, building walls and methods. An example drainage channel includes a drainage panel for conveying water within a building wall. The drainage panel is impermeable and has a first end and a second end. A support panel is coupled to the first end or the second end of the drainage panel such that the support panel is configured to be arranged vertically relative to the building wall. The drainage panel is configured to be arranged either perpendicular to an exterior sheathing of the building wall or angled downward from the first end of the drainage panel toward both the second end of the drainage panel and the exterior sheathing of the building wall.
Claims20
A drainage system for attachment to an exterior sheathing of a panel structure, the drainage system comprising:
- a weather resistive barrier coupled to the exterior sheathing, wherein the weather resistive barrier forms a secondary drainage plane of the drainage system;
- an insulating material coupled to the exterior sheathing, wherein the insulating material is positioned outboard of and adjacent to the weather resistive barrier;
- a water channel material coupled to the exterior sheathing, wherein the water channel material is positioned outboard of and adjacent to the insulating material, and wherein the water channel material forms a primary drainage plane of the drainage system;
- a lath member coupled to the exterior sheathing, wherein the lath member is positioned outboard of and adjacent to the water channel material;
- and
- a drainage channel comprising (i) a drainage panel for conveying water within a building wall, wherein the drainage panel is impermeable and comprises a first end and a second end, and (ii) a support panel coupled to the first end or the second end of the drainage panel such that the support panel is configured to be arranged vertically relative to the building wall, wherein the drainage panel is configured to be arranged either perpendicular to an exterior sheathing of the building wall or angled downward from the first end of the drainage panel toward both the second end of the drainage panel and the exterior sheathing of the building wall, wherein the support panel is a front panel coupled to the first end of the drainage panel, and wherein the front panel is coupled to the lath member and arranged outboard of the insulating material, wherein the first end of the drainage panel is positioned outboard of the water channel material such that any water from the primary drainage plane is directed inboard toward the weather resistive barrier.
A method of installing a drainage channel within a building wall, wherein the building wall comprises (a) a weather resistive barrier coupled to an exterior sheathing, wherein the weather resistive barrier forms a secondary drainage plane of a drainage system;
- (b) an insulating material coupled to the exterior sheathing, wherein the insulating material is positioned outboard of and adjacent to the weather resistive barrier;
- (c) a water channel material coupled to the exterior sheathing, wherein the water channel material is positioned outboard of and adjacent to the insulating material, and wherein the water channel material forms a primary drainage plane of the drainage system;
- and (d) a lath member coupled to the exterior sheathing, wherein the lath member is positioned outboard of and adjacent to the water channel material, and wherein the drainage channel comprises (a) a drainage panel for conveying water within the building wall, wherein the drainage panel is impermeable and comprises a first end and a second end, and (b) a support panel coupled to the first end or the second end of the drainage panel such that the support panel is configured to be arranged vertically relative to the building wall, wherein the drainage panel is configured to be arranged either perpendicular to the exterior sheathing of the building wall or angled downward from the first end of the drainage panel toward both the second end of the drainage panel and the exterior sheathing of the building wall, wherein the support panel is a front panel coupled to the first end of the drainage panel, the method comprising:
- positioning the front panel of the drainage channel outboard of the water channel material such that any water in the secondary drainage plane is directed to a drainage well and any water in the primary drainage plane is directed to the drainage well via a drainage panel of the drainage channel;
- and
- coupling the lath member to the front panel of the drainage channel such that the front panel is arranged outboard of the insulating material.
