Abstract
A wall cladding panel comprising a substantially planar front face, a rear face comprising a plurality of drainage channels and a plurality of spacer sections disposed between the drainage channels, and an edge member disposed contiguously between the front face and the rear face. The wall cladding panel is locally thinner at the drainage channels than at the spacer sections. Each drainage channel is configured to form a liquid flow path and/or an air gap when a substantially planar building surface is placed adjacent to the rear face. A plurality of wall cladding panels with drainage channels may be arranged in series to cover at least a portion of a building.
Claims23
A building system comprising:
- a weather resistant barrier disposed external to a building substrate;
- at least one fiber cement wall cladding panel fixed to the weather resistant barrier and the building substrate such that the at least one fiber cement wall cladding panel is external to the weather resistant barrier and forms an exterior of the building system, the at least one fiber cement wall cladding panel comprising:
- a substantially planar front face configured to face away from the weather resistant barrier and building substrate when the wall cladding panel is fixed thereto;
- a rear face configured to face toward the weather resistant barrier and building substrate when the wall cladding panel is fixed thereto, the rear face comprising a plurality of integrally formed drainage channels arranged in a plurality of groups of adjacent drainage channels, the plurality of groups of adjacent drainage channels separated by one or more spacer sections, wherein each of the drainage channels comprises a curved channel surface having a c-shaped cross-section;
- and
- an edge member disposed contiguously between the front face and the rear face, wherein each of the plurality of integrally formed drainage channels has a depth that is between approximately 8% and approximately 60% of a thickness of the edge member;
- and
- a plurality of air gaps, each air gap being bounded by a portion of the weather resistant barrier and one of the drainage channels of the rear face, wherein each air gap comprises a liquid flow path.
A wall cladding panel comprising:
- a fiber cement substrate having a substantially planar front face, a rear face, and an edge member disposed contiguously between the front face and the rear face;
- the rear face comprising a plurality of substantially parallel drainage channels arranged in one or more groups of adjacent drainage channels, the one or more groups of adjacent drainage channels positioned adjacent to one or more spacer sections, each of the plurality of substantially parallel drainage channels comprising a curved channel surface, wherein the wall cladding panel has a first thickness at the one or more spacer sections and a second thickness at the drainage channels, and wherein the second thickness of the wall cladding panel at the drainage channels is between approximately 8% and approximately 60% of the first thickness of the wall cladding panel at the spacer sections;
- and
- wherein each drainage channel is configured to form a liquid flow path when a substantially planar building surface is placed adjacent to the rear face, and wherein the front face is configured to face away from the substantially planar building surface when the building surface is placed adjacent to the rear face of the wall cladding panel.
A method of mounting a wall cladding panel to a building substrate having a weather resistant barrier mounted thereon, the method comprising:
- obtaining a first wall cladding panel made of fiber cement, the first fiber cement wall cladding panel comprising:
- a substantially planar front face;
- a rear face comprising a plurality of substantially parallel drainage channels arranged in one or more groups of adjacent drainage channels, the one or more groups of drainage channels positioned adjacent to one or more spacer sections, wherein each of the plurality of substantially parallel drainage channels comprises a curved channel surface;
- and
- an edge member disposed contiguously between the front face and the rear face, wherein each drainage channel is configured to form a liquid flow path when a substantially planar building surface is placed adjacent to the rear face, and wherein each of the plurality of drainage channels has a depth that is between approximately 8% and approximately 60% of a thickness of the edge member;
- placing the first fiber cement wall cladding panel adjacent to the building substrate such that the rear face is parallel to and abutting the weather resistant barrier;
- and
- fixing the first fiber cement wall cladding panel through the weather resistant barrier to the building substrate to form a plurality of liquid flow paths, each liquid flow path comprising an air gap bounded by a portion of the weather resistant barrier and one of the drainage channels of the rear face.
