The exterior walls of buildings are comprised of multiple elements that provide structural support and bracing as well as weather protection for the structure and the interior elements of the building. Typical structural elements include columns, beams, studs, and sheathing. Weather protection elements include siding, panel siding, trim, various cladding systems, and, in some cases, the sheathing. When used on the exterior of a building, sheathing may be applied to the outer face of studs, roof trusses, or rafters of the building to brace the structure, resist wind and other loads and to provide a backing for the exterior weatherproofing systems. In cases, the sheathing itself can serve as one of the weatherproofing elements of the building. Sheathing can be manufactured from a variety of materials including wood, cement, gypsum, insulation, foam insulation, or other suitable materials. Sheathing panels are typically attached directly to wall framing or roof framing members and are typically covered with a wall cladding, siding, or roofing. One example of sheathing is Oriented Strand Board (“OSB”). OSB is a wood and resin based sheathing product typically manufactured in four foot by eight foot sheets. The OSB sheathing is an engineered product used in wood frame construction in applications that historically used plywood or solid sawn wood members. OSB sheathing is typically manufactured with smooth or slightly roughened faces and can be used as a subfloor, roof sheathing, or wall sheathing, among other uses. When used as roof sheathing, the roughened surface of the OSB provides a slip resistant walking surface. When used as wall sheathing, the OSB is nailed or screwed to supporting wood framing. OSB sheathing is not oriented in a particular horizontal or vertical manner and can be cut into different sizes and shapes to sheath the underlying wood framing or furring.
Cladding may be formed from wood, “hardboard” or “pressboard,” plastics, cement, gypsum, insulation, foam insulation, or other suitable materials. Cladding is generally referred to as an external weatherproofing element that is attached to the exterior sheathing or framing. The cladding is typically applied over a weather resistant membrane (as used herein the term includes building paper, felt, house-wrap, and similar products including liquid or spray applied breathable coatings). In addition to siding, trim, and panel siding, cladding systems include stucco, brick, stone and other materials used to cover the building and provide weather protection. Trim, siding, panel siding, and other cladding systems can trap moisture behind the cladding systems resulting in degradation of the building paper, underlying sheathing, and the wood framing.
Cement board siding, wood siding, and ‘hardboard’ siding or ‘pressboard” siding are typically manufactured with a smooth ‘back’ or unexposed face, and a ‘front’ or exposed face, of the siding with a smooth finish or decorative patterns that simulate wood grain. Siding is a subset of cladding that is typically layered, or “lapped,” on the exterior surface of the structure to shed water. For siding, the typical installation of the siding is lapped with the upper pieces of siding overlapping the lower pieces of siding as the siding is installed up the typical exterior wall face. This lapped siding installation allows water to shed down the exposed face of the siding. The ‘back’ or un-exposed face of the siding is typically in contact with the underlying sheathing or building paper. The siding is nailed through the face of the siding, through the sheathing if present, and into the underlying wood framing (studs) of the wall assembly. Some water will reach the back side of the siding and/or the face of the building paper, during rain, snow, or condensation events. In traditional siding, at each level of the siding installation, the back side of the siding is tight against the building paper. At these contact points, or ‘pinch points’ the flow of water down the building paper is potentially obstructed. In addition, the ventilation of the space behind the siding is potentially obstructed. In traditional siding, the back of siding cannot ‘breathe’ resulting in potential degradation of the building paper, underlying sheathing, the wood framing.
To reduce the potential for damage due to moisture and to create an omnidirectional ventilation space behind the siding, trim, or cladding, one embodiment of the present invention introduces raised patterns or bumps to the manufactured back side of siding, trim, or cladding. These raised bumps or patterns create a permanent, omnidirectional, air space and are integral to the manufactured siding, trim or cladding product.
To reduce the potential for damage due to moisture and to create a ventilation space between sheathing and the covering siding or cladding, one embodiment of the present invention introduces raised patterns or bumps to an outwardly facing surface of the sheathing. These raised bumps or patterns create a drainable ventilation space between the sheathing and siding, panel, or cladding materials that form the outer surface of a structure. The patterned sheathing may be covered with a spray applied weather resistant membrane, or other coating, providing increased weather resistance while maintaining the omnidirectional ventilation and drainage air space.
In an embodiment, a vented and water control panel for securing to the exterior of structure includes an omnidirectional relief pattern formed on a back surface of the vented and water control panel. The omnidirectional relief pattern forms an omnidirectional ventilation and drainage plane for moving water and water vapor. The vented and water control panel may be siding, trim-board, siding panel, or cladding element.
In an embodiment, a vented and water control panel sheathing is disclosed. The vented and water control panel sheathing includes a panel body having an outer face, and an inner face. The panel sheathing further includes a plurality of raised surface features extending from the outer face in the form of an omnidirectional relief pattern to provide points of contact between the sheathing and an exterior finish or cladding, when the exterior finish or cladding is applied with the sheathing. Also, a plurality of channels is formed between the raised surface features to facilitate omnidirectional draining and/or ventilation between the panel and the applied exterior finish or cladding. If used as an insulating panel, the sheathing may have an omnidirectional relief pattern on both the outer and inner face (both faces) of the panel.
In another aspect, a structure has improved water drainage and air ventilation, the structure includes a first layer having an interior facing surface and an exterior facing surface, the exterior facing surface having an omnidirectional relief pattern of raised elements thereon; wherein the omnidirectional relief pattern forms an omnidirectional ventilation and drainage plane.
Disclosed is a vented and water control siding, trim-board, cladding, and sheathing with improved omnidirectional drainage and integrated air space. The vented and water control siding, trim-board, or cladding may be formed as long, narrow sheets used in siding the exterior of a buildings, is fabricated with an omnidirectional relief pattern formed on the on its back (unexposed) surface. Omnidirectional relief pattern, as used herein means a three-dimensional pattern of raised elements (or lowered elements) on the plane of a surface that allows for air ventilation or moisture drainage in any direction, and not solely a linear direction. The omnidirectional relief pattern holds the siding, trim-board, or cladding away from a structure to which it is secured (hereinafter called “the structure”), thereby providing a ventilation and drainage plane between the back surface of the siding and the structure. This drainage plane provides an omnidirectional path for air and water to flow, and is therefore an omnidirectional drainage plane. An omnidirectional path here means a path for a flow (e.g., air, water, or water vapor) to move substantially unimpeded both along a siding's or series of siding's length and width.
The vented and water control sheathing may be formed as sheets or panels used in sheathing the exterior of a buildings, is fabricated with an omnidirectional relief pattern formed on its front surface. The omnidirectional relief pattern holds subsequent siding or cladding away from the sheathing, thereby providing a drainage plane between the front surface of the sheathing and the siding or cladding. This drainage plane provides an omnidirectional drainage plane.
In the present description, the omnidirectional relief pattern is shown and described as a grid (or array) pattern of raised bumps or “dot” shaped structures and an egg-crate or other three-dimensional pattern of raised features, but it will be understood that any pattern and shaped structures that facilitates an omnidirectional drainage plane can be used without departing from the scope herein. For example, the “bumps” may be pyramids, squares, rectangles, or other shapes may be formed in a grid pattern. A feature of the raised “dot” and “egg-crate” shaped structures is the air space on all sides of the raised shaped structures, which facilitates water and air flow.
By providing an omnidirectional ventilation and drainage plane the risk of moisture related damage to the structure is significantly reduced. The omnidirectional drainage plane provided by the raised patterns allows moisture to spread unhindered over a large surface area, as such drainage is improved and an integrated air space is provided. This differs from the prior art structures, for example using furring strips or similar structures that only provide for a limited substantially linear drainage plane. For example, U.S. Pat. No. 7,472,523 to Beck (“the '523 patent”), entitled “Rainscreen Clapboard Siding” discloses siding with linear protrusions or recesses on the backside of clapboard siding. These protrusions are described as “preferably oriented substantially vertical to the bottom edge 106, i.e., perpendicular to the bottom edge, but may vary as much as ±85° from vertical.” (3:38-41). The vertical and horizontal protrusions or recesses of the '523 patent fail to provide omnidirectional drainage, but instead are limited to a linear drainage plane defined by the direction of the vertical or horizontal protrusions/recesses. In addition, the present system eliminates the need for additional structure, such as furring strips, which increase cost and associated with additional material and labor.
The prior art systems that utilize a linear drainage plane contain moisture in a restricted space, which may cause the linear drainage plane to become saturated. Additionally, air flow is limited, which would otherwise facilitate the removal of moisture and drying of the assembly. The omnidirectional pattern of the present invention resists saturation and allows air flow from any direction. The present invention resists plane saturation by allowing moisture to disperse over a large surface area. This has the additional benefit of exposing the moisture to substantially unrestricted air flow, increasing the rate of moisture removal by transferring moisture from the provided space to the moving air.
Siding, trim-board, cladding, or sheathing with an omnidirectional relief pattern formed on one surface may be fabricated from a number of materials, such as, but not limited to, OSB, cement, fiber reinforced cement, gypsum, paper backed gypsum, insulation, foam insulation, wood or wood products, etc.
Patterned Siding
Window 120 shows a back surface 114 of siding 110. Formed on back surface 114 of siding 110 is an omnidirectional relief pattern formed as a grid of raised elements 112. When secured to structure 150, raised elements 112 space back surface 114 of siding 110 away from sheathing 154 or optional barrier 156, thereby creating an omnidirectional drainage plane 116 (arrows shown are exemplary of drainage plane 116 only, and do not limit drainage to any particular direction within plane 116).
In the present example, siding 110 is formed from fiber cement material with raised elements 112 formed on back surface 114 utilizing an embossing process, although other materials and techniques may be used without departing from the scope herein.
In the embodiment of
In an embodiment, siding 262 is fabricated with a thickness of approximately ½ of an inch, that is, ⅜ of an inch of substantially solid material and ⅛ of an inch for the embossed three-dimensional pattern, and approximately 6 inches wide. The separation distance 229 between the peaks on siding 262's exemplary egg-crate pattern are spaced such that during installation, for example, by fixing to structure 250 with nails or screws, siding 262 is not prone to cracking. An exemplary separation distance 229 is ½ of an inch, although this may vary depending on the type of material used to make siding 262, the thickness of siding 262, etc. In an embodiment, a height 230 of the three-dimensional pattern is optimized to facilitate drainage while maintaining structural integrity. In this embodiment, height 230 is ⅛th of an inch. It will be understood that separation distance 229 and height may be selected to be greater than or less than the measurements disclosed here, for example, to compensate for environments with more or less humidity. Further, the height of the omnidirectional relief pattern elements may taper from the top of the siding or panel to the bottom of the siding or panel, or vice versa. It will be understood that siding 262 may be formed with any industry standard dimension, or any other dimension, without departing from the scope herein. The length of siding 262 may be of any industry standard length, for example, that conforms to fabrication and installation practices.
It will be understood that raised elements 212, 228 may additionally be utilized for alignment purposes during installation of siding 210, 262 by aligning raised elements 212, 228 with the outer top corner of the next lowest, adjacent siding 210, 262, as shown in
In the preferred embodiment, siding 110, 210, 262, 322, 372, is fabricated from a cement board or similar fiber-cement composite. In one example of fabrication, the raised features, such as raised elements 112, 212, 228, 312, 328, formed on siding 110, 210, 262, 322, 372 are formed using an embossing processes. Alternatively, siding 110, 210, 262, 322, 372 may be fabricated from any material know in the industry that may benefit from ventilation and moisture drainage between siding and a structure to which it is secured.
Raised features may be a bump or dot pattern similar to that shown in
In an alternative embodiment, siding, similar to siding 210, 262, may be fabricated to include, within a series of recesses (not shown) at the lower portion of its back surface, a moisture reactive material (not shown), one example of which is bentonite. In the situation where moisture contacts the moisture reactive material, the material expands thereby pushing the lower portion 216, 236 of siding 210, 262 away from the upper portion 217, 237 of the next lowest siding 210, 262. This process creates a drainage channel at location 218, 238 during wet conditions and closes the drainage channel during dry conditions. In this configuration, siding 210, 262 is formed of, with, or includes a semi flexible material, such that the expansion of the moisture reactive material does not fatigue or otherwise damage the siding.
In the embodiment of
In an embodiment, starter strip 365 is formed with raised elements (not shown) similar to raised elements 328 to act an additional egress for water or water vapor and to increase ventilation.

Patterned Panels
It will be understood that panels may be fabricated from any number of materials that accepts a pattern, for example, by embossing or patterning, such as Oriented Strand Board (OSB), cement board, fiber-cements board, Medium Density Fiberboard (MDF), Gypsum sheathing, insulation, foam insulation, or any other material. Even though the present invention is suitable for use with any of many products, the invention will be disclosed in the context of OSB sheathing from this point forward.
As shown in
Fine wood strands of upper layer 716 facilitate stamping or embossing surface features 708 into outer face 704, as further described with respect to
Sheathing 700 may also be formed from other materials including, but not limited to, fiber reinforced cement, gypsum, paper backed gypsum, insulation, foam insulation, wood, metal, or other materials. For example, in one embodiment, a foam panel is press molded one surface to include features (similar to features 708). Upon insulation, the features are installed facing exteriorly from the structure to provide an omnidirectional drainage and ventilation path for moisture and air between the sheathing and attached siding, cladding, or trim-board.
Sheathing 700 may also include other features discussed herein. For example, sheathing 700 may include overlapping structures (such as structures 430(A) and 430(B), and 452(A) and 452(B), discussed above) such that adjacent panels of sheathing 700 overlap and are substantially in the same plane when installed. Alternatively, sheathing 700 may be butt jointed with adjacent sheathing panels and include flashing (such as flashing 466) therebetween such that adjacent sheathing panels are substantially in the same plane when installed. In addition, sheathing 700 may include an omnidirectional relief pattern on both a front and back side. By including omnidirectional relief pattern on both sides, sheathing 700 will provide an omnidirectional drainage and ventilation path on the exterior facing side. Also, the interior facing side will reduce thermal bridging where the panel meets the stud. Thus, the omnidirectional relief pattern on the internal side will increase the energy efficiency of the structure, particularly where steel studs are used in the construction of the structure.
A water-resistant barrier 722 (
The above described panels and siding may be used within a stucco (also referred to as exterior plaster, or exterior cement plaster) finish.
Stucco wall 1900 includes wall framing 1902. Sheathing 1904 is coupled to framing 1902 to provide structural support and backing to the cladding or siding and to transmit loads to the structural framing. Therefore, sheathing 1904 may be defined as a structural wood panel or structural board. One example of such sheathing 1904 is described in U.S. Patent Application Publication No 2009/0113838 to Paulsen, which shows “sheathing 502” attached to “framing 501” in
To build a typical three-coat stucco finish on wall 1900, a weather barrier 1906 may be applied to sheathing 1904. Then a lath 1908 may be applied to weather barrier 1906. In some instances, lath 1908 may be applied directly to sheathing 1904. Lath 1908 may be welded wire lath, woven wire lath, expanded metal lath, flat rib lath, plastic lath, or other similar materials that the stucco material is keyed into. The stucco is applied to the metal lath to fully key the metal lath in the stucco. Keyed into the lath 1904 is a first stucco coat 1910. This first stucco coat 1910 is often referred to as a ‘scratch coat’. On top of first stucco coat 1910 is a second stucco coat 1912. This second stucco coat 1912 is often referred to as a ‘brown coat’. Then, a third stucco coat 1914 is applied to second stucco coat 1912. This third stucco layer 1914 is often referred to as the ‘finish’ coat, and may be painted or otherwise colored. Within the stucco layers 1910, 1912, 1914 may be one or more vertical or lateral control joints 1916.
Wall 1900 has many disadvantages. First, the labor to apply the sequential coats of stucco is time consuming and costly. Moreover, each individual first, second, and third stucco coat 1910, 1912, 1914 must be applied individually, and then allowed to cure in accordance with a specific standard and building code requirement before the next coat can be added. The successive coats of stucco fill cracks in the coats below and produce a finish with less visible cracking. The sequential layers of cement plaster, each contain various amounts of aggregate and cement to cover cracks and imperfections in the prior coat of cement plaster. The present embodiments disclosed herein solve these disadvantages and reduces labor costs and greatly reduces or eliminates the curing time of successive coats of cement plaster.
Exterior panels 2102, 2104 may be any of the above discussed panels or siding (e.g. siding 110, 210, 262, 322, 372, 410, 420, 465, 475, or any other siding or panel discussed herein). Moreover, a back surface of exterior panels 2102, 2104 may include one or more raised elements to provide an omnidirectional drainage and ventilation path similar to any of raised elements 112, 212, 228, 312, 328, 442, 467 or any other raised elements discussed above. Therefore, exterior panels 2102, 2104 benefit from the ventilation and water drainage advantages discussed herein.
Further yet, exterior panels 2102, 2104 may or may not include overlapping portions 2110, shown in
Exterior panels 2102, 2104 may be of one piece construction and may comprise cement, metal, wood, woodbased, plastic, or other material including composites of these materials.
Exterior panels shown in
In step 2502 of method 2500, a structural layer may be installed on framing of a structure. In one example of step 2502, sheathing 2106 may be installed on framing 2108 of a structure.
In step 2404 of method 2500, a non-structural layer forming a base layer for a finishing layer of the structure is applied to the structural layer. In one example of step 2504, exterior panels are applied to the sheathing 2106, such as exterior panels 2102, 2104, and 2204.
In embodiments that include step 2506 of method 2500, a joint reinforcement may be applied to the non-structural layer applied during step 2404. In one example of step 2506, joint reinforcement 2202 is applied to exterior panels 2102, 2104 and 2204. In step 2506, joint reinforcement 2202 may be applied to substantially the entire surface of panels or only at the joints thereof. In one example of step 2506, joint reinforcement 2202 may be applied to every other joint between pluralities of exterior panels.
In step 2508 of method 2500, a finishing layer is applied to the previously generated layers. In one example of step 2508, finishing layer 2402 is applied to joint reinforcement 2202, or alternatively directly to exterior panels 2102, 2104, and 2204.
Patterned Trim-Board/Molding:
The disclosed trim-board/molding provides ventilation and water control by providing a raised pattern on the inward facing surface of the trim-board/molding. Examples of a pattern utilized on the trim-board/molding is a pattern of raised bumps/dots 1444 as shown
Water control trim-board/molding 1465 may be manufactured using a number of different materials, examples of which include but are not limited to, fiber cement, hardboard, OSB, PVC, wood fiber/resin composite, gypsum, foam, foam insulation, and glass fiber reinforced plastic composite.
The example of a pattern utilized on the trim-board/molding of
Water control trim-board/molding 1475 may be manufactured using a number of different materials, examples of which include, but are not limited to, fiber cement, hardboard, OSB, PVC, wood fiber/resin composite, gypsum, foam, foam insulation, and glass fiber reinforced plastic composite.
While the present invention has been described above, it should be clear that many changes and modifications may be made to the process and product without departing from the spirit and scope of this invention. For example, although pattern 706 is illustrated as a non-directional assortment of round bumps, other omnidirectional raised patterns (pyramids, squares, squiggles or other geometric or random shapes) may also provide drainage channels therebetween. Likewise, a sunken pattern of incuts may be formed into face 704 in place of or in addition to raised surface features 704, such that face 704 provides for attachment to an exterior finish, such as siding or cladding, and the incut pattern forms channels 710.
Patterned Insulation:
Although insulation 1502 is illustrated having omnidirectional relief pattern on the interior surface thereof, in an alternate embodiment, insulation 1502 may have an omnidirectional relief pattern on both the interior surface and the exterior surface thereof. Therefore, standard sheathing and standard siding or cladding may be attached to insulation 1502 while maintaining an omnidirectional drainage and relief path between each layer.
Omnidirectional drainage and ventilation provides significant advantages. As compared to linear drainage and ventilation systems, such as those with horizontal or vertical grooves or protrusions, the omnidirectional path provides an easier path for drainage and ventilation. Further, should one path get impeded, for example by dirt and debris, the air and moisture is easily redirected through another path. Moreover, the omnidirectional relief pattern may be manufactured using pressboard molding, stamping, or otherwise engraving. This simplifies manufacturing and thereby reduces associated costs. Further, because the omnidirectional relief pattern is not limited to a particular direction, large panels may be manufactured with the omnidirectional relief pattern and then cut into smaller sections without concern for the direction of the relief pattern. Additionally, where sheathing or insulation includes an omnidirectional relief pattern on an exterior (or interior) facing surface thereof, standard siding may be utilized while still achieving the moisture drainage and air ventilation benefits discussed herein.
