The following disclosure is directed to a wall system for receiving cladding. The wall system offers improved water drainage, and diminished probability of occurrence of mold, mildew and rot formation behind the cladding. The wall system is also inexpensive, and simple to install and use. In addition, the wall system is generally material agnostic, and may be used as an interface between a structural wall (including sheathing, house wraps, gauge-metal framing, and felt), and exterior-façade materials, including, but not necessarily limited to: faux masonry, faux stone, stone, brick, mortar, stucco, and other aesthetic or exterior-façade materials.
The following disclosure is also directed to systems and methods of attaching faux or natural stone, and other artificial or natural aesthetic-façade materials to a wall.
Most building codes in the United States require that a water-resistive barrier or non-water-absorbing layer or designed-drainage space be installed before application of a hard-coat stucco or faux stone or other veneer.
Nevertheless, many veneers adhered to the exterior wall (i.e., sheathing, house wraps, metal framing, and felt) still trap moisture behind the veneer. This can lead to damage and rot to the interior structure of a building, and mold issues. In addition, many of these systems often attract wood-destroying insects such as termites, and carpenter ants.
In particular, the advent of faux-stone veneer in recent years, has led to the finding that many of these wall systems were either improperly installed, or had improper water drainage or vapor-permeable barriers between the faux stone, and sheathing or housing wraps.
Consequently, many houses and buildings that use or used faux stone, will experience moisture and insect problems that result in 100% removal of the faux stone, and major structural repairs.
On the other hand, the advantage of not requiring a stone mason to install stone veneer to the side of a building is appealing to the construction industry. Further, because faux stone does not require mortar for their attachment means to a wall, there are less weather and seasonal restrictions to installations. So, faux-stone veneer is desirable to the consumer and building industry, because it is generally less expensive and quicker to install than natural stone. But attaching simulated stone to the sides of walls requires careful attention to water and mold, and requires expertise.
Thus, there remains a need for a simplified wall system for attaching cladding of all types, including faux stone. Such a wall system should offer water drainage, and diminished probability of occurrence of mold, mildew and rot formation behind the cladding.
In addition, there is a need for simplified method and system of attaching individual faux stones to a wall, requiring less time, expertise, and material to install.
The following disclosure is directed to a wall system for receiving cladding. The wall system offers improved water drainage, and diminished probability of occurrence of mold, mildew and rot formation behind the cladding. The wall system is also inexpensive, and simple to install and use. In addition, the wall system is generally material agnostic, and may be used as an interface between a structural-wall sheathing (including house wraps, gage-metal framing, and felt), and exterior-façade materials, including, but not necessarily limited to: faux masonry, faux stone, mortar, stucco, and other aesthetic or exterior-façade materials.
In one aspect, wall system includes a structural-separation-plane panel, a matrix, and a plurality of spacers. The panel is generally planar, and includes a back surface, and front surface. The front surface may be substantially flat and planar. Alternatively, the front surface may include one or more patterns and shapes.
In one aspect, matrix is a nylon mesh. That is, the matrix includes a mesh of interwoven-nylon strands. The matrix is embedded into the front surface of the panel when the panel is in a liquefied state (such as a mold). But as appreciated by those skilled in the art having the benefit of this disclosure, the matrix may be coupled to the panel by other means such as glue, staples, tacks, or other coupling means. As a whole, the matrix is permeable to both air and water.
The spacers are bumps that protrude from the back surface of the panel. That is, the spacers extend from the back surface of the panel, and form channels for drainage of water when the panel is secured to the wall. That is, spacers are sandwiched between the back surface, and an exterior-most portion of the wall of a building, thereby forming channels for drainage of water. The channels provide open drainage space for water, and do not catch or contain water.
The spacers may include different shapes, and dimensions. In one example, each spacer is approximately ⅛ of an inch thick measured from the back surface of the separation panel extending to a back surface of each spacer. Further, each spacer is molded into, or a part of the back surface of the panel.
Various other examples of wall systems (and constituent parts, shapes, and sizes) for attaching materials are described in the Detailed Description below, and are illustrated in the drawings.
The following disclosure is also directed to systems and methods of attaching faux stone and natural or other man-made materials to a wall.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below. This summary is not necessarily intended to identify key features or essential features of the claimed subject matter, nor is it necessarily intended to be used as an aid in determining the scope of the claimed subject matter.
Reference herein to “example,” “embodiments” or similar formulations means that a particular feature, structure, operation or characteristic described in connection with the example, is included in at least one implementation in this description. Thus, the appearance of such phrases or formulations herein are not necessarily all referring to the same example. Further, various particular features, structures, operations, or characteristics may be combined in any suitable manner in or more examples.
The detailed description is described with reference to the accompanying figures. In the figures, the left-most digit(s) of a reference number identifies the figure in which the reference number first appears. The figures are not necessarily drawn to scale.
Panel 104 is generally planar, and includes a back surface 110, and front surface 112. In one example, panel 104 is fiberglass. However, as will be appreciated by those skilled in the art, after having the benefit of this disclosure, panel 104 may be constructed of other light-weight materials such as polymeric materials, as will be discussed in other examples below.
In one example, panel 104 is approximately 1/16 of an inch thick measured from back surface 110 to front surface 112, but as will be apparent to those skilled in the art having the benefit of this disclosure, panel 104 may be other suitable thicknesses greater or smaller than 1/16 of an inch, such as, but not necessarily limited to: 1, 3/32, ¼ or ⅛ of an inch thick. Front surface 112 is may be substantially flat and planar. Alternatively, as will be described below, front surface 112 may include one or more patterns and shapes.
In one example, matrix 106 is a nylon mesh. That is, matrix 106 includes a mesh of interwoven-nylon strands 114. However, matrix 106 may include other suitable waterproof materials, such as but not limited to plastic, polyethylene, or polyester. In one example, matrix 106 is about 3/16 inch to ¼ inch thick, but may include other suitable thickness (greater or less than the aforementioned thicknesses).
In one aspect, matrix 106 is the nylon mesh portion of drainage mats, such as Driwall™ Rainscreen 075-1 mats from Keene company, Mayfiled Heights, Ohio, USA. Alternatively, mesh may also include fused and entangled filaments manufactured by Enka, or Benjamin Obdyke and others.
Matrix 106 is fastened to front surface 112 of panel 104. In one example, matrix 106 is embedded into front surface 112 of panel 104, when panel 104 is formed. But as appreciated by those skilled in the art having the benefit of this disclosure, matrix 106 may be coupled to panel 104 by mechanical means such as glue, staples, tacks, or other coupling means. As a whole, matrix 106 is permeable to both air and water.
Referring back to
Spacers 108 may include different shapes, and dimensions. For instance, in one example, each spacer 108 is approximately ⅛ of an inch thick measured from back surface 110 of panel 104 to a back surface 118 of each spacer 108. Further, each spacer 108 is simply molded into back surface 110 of panel 104. That is, each spacer 108 is formed when molding panel 104. Alternatively, one or more spacers 108 may be attached to panel 104, and may not necessarily be an integral part of panel 104. For instance, it may be desirable to attach spacers after the panel 104 is formed from a molding process (if a molding process is used).
However, each spacer 108 may come be of in different sizes and shapes, and distances apart from each other, so as not to catch or retain water as would be appreciated by those skilled in the art. For instance, spacers 108 may be circular, triangular, square, rectangular, star shaped or other suitable shapes as would be appreciated by those skilled in the art, after having the benefit of this disclosure. The water-drainage cavity (i.e. plane) formed on the backside of the separation panel from spacers—or other means such as mesh—is usually between about ⅛ of an inch and about three inches.
In addition, the ratio between spacers and no spacers may vary. So, the shape, depth and size of each spacer may vary, and ratio of spacers to no spacers may vary. Still further, spacers 108 may not crisscross at an angle. Instead, each spacer may be aligned in rows and columns, with each spacer in alignment with the other.
In addition, channels 116 may be formed by other means, such as by ribs, grooves, or other shaped protrusions formed on either back surface 110 of panel 104 or on a major surface of wall 102 (including sheathing, house wrap, felt, etc.).
Referring back to
In one example, a liquid applied waterproofing air barrier or DuPont's Tyvek® felt may be applied to wall 102 before fastening panel 104 to wall 102. Panel 104 may be nailed or screwed into plywood at different intervals. In one example, the fasteners 122 are inserted in the middle of each spacer 108. As would be appreciated by those skilled in the art, fasteners 122 may include nails, screws, staples or other fastening means (such as adhesives in the alternative).
Veneer, such as faux stones 120, may be fastened to a front face 124 of system 100 by structural (such as screws, nails or other fastening means) or chemical means (such as glue, adhesive, or mortar). Front face 124 faces away from wall 102. In addition, stucco (in lieu of veneer), and mortar may be adhered directly to matrix 106.
Veneer, such as faux stones 120 (see, e.g.,
Veneer, such as faux stones 120, may be fastened to panel 104 of system 500 by fastening means such as mortar, glue, adhesive, screws, nails, a combination of the foregoing, or other fastening means. In addition, stucco (in lieu of veneer), and mortar may be adhered directly to mesh 506.
Referring to
In addition, a bonding material 1506, such as cement, mortar and/or glue, may be applied to matrix 106 of system 1500 before each stone 1502 is attached. Next, each stone 1502 may be fastened to wall 102 using a fastener 1504, thereby holding the stone 1502 in place while bonding material 1506 cures. The fastener 1504 may remain in place after curing, for additional strength. If the fastener 1504 is thin enough, and of similar colors to stone, it cannot generally be seen by a casual observer. For instance, if stainless steel-pin nails are used (slightly countersunk into each stone 1502) then a casual observer should not perceive that the stones are secured to a wall by nails.
In addition, pins 1602 may have pre-adhesive materials applied to them before each stone 104 is affixed thereto. After each stone 1502 is slid onto one or more pins 1602, the stones become affixed thereto, pins 1602 are hidden from view. Because each stone is securely attached individually, and held in place by pins 1602 and possibly glue and mortar too, stones 1502 should not fall or become dislodged from wall 102, even if mortar or glue becomes ineffective over time.
At distal edges 2004(A), 2004(B) of each panel 2002 there may be a mechanical interconnect system 2006 to fasten panels 2002 to each other. For instance,
Exemplary embodiments have been disclosed herein, and although specific terms are employed, they are used and are to be interpreted in a generic and descriptive sense only and not for purpose of limitation. For example, it will be understood that when a layer is referred to as being “on” another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may also be present.
Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described. Rather, the specific features and acts are disclosed as illustrative forms of implementing the claims.
This application is a continuation of prior U.S. application Ser. No. 14/321,489 filed Jul. 1, 2015, which is fully incorporated by reference.
