Abstract

Aspects of the disclosure relate to lath/rainscreen assemblies including a sheet defining lath and rainscreen faces, first and second ends, and first and second sides. A plurality of protrusions extend from the rainscreen face and also optionally the lath face. The protrusions on the lath face in combination with the lath face provide a substrate for application of a stucco veneer. If no protrusions are provided on the lath face, the lath face can be secured to siding. The rainscreen face and protrusions of the rainscreen face collectively form channels through which moisture can drain to a weep screen or the like. Each of the lath face and the rainscreen face include area free of protrusions so that multiple lath/rainscreen assemblies can be secured to the structure in an overlapping fashion. Methods of installing and making lath/rainscreen assemblies are also disclosed.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application Ser. No. 62/772,740, filed Nov. 29, 2018, which is incorporated in its entirety herein by reference.

FIELD

The present technology is generally related to laths, rainscreens and methods of installation and manufacture.

BACKGROUND

Developments in the construction of buildings has generally resulted in “tighter” buildings, thus meaning there is less airflow leakage and between the interior and exterior of the building. As a result, “tighter” buildings have an increased risk for moisture and mold problems. Known rainscreen systems reduce the risk of moisture and mold damage by enabling moisture that has penetrated an exterior siding material to swiftly exit the building envelope.
The present disclosure addresses problems and limitations associated with the related art.

SUMMARY

The techniques of this disclosure generally relate to a combination lath and rainscreen provided in a single assembly. Various embodiments of the disclosure simplify installation as well as reduce labor costs and requirements. In addition, various embodiments of the disclosure are non-corrosive and are metal-free.
In one aspect, the present disclosure provides a lath/rainscreen assembly including a sheet or strip defining a lath face and a rainscreen face, a first end and a second end, and a first side and a second side. In one embodiment, the lath/rainscreen assembly further includes a plurality of protrusions extending from the lath face and the rainscreen face. The lath face includes a first area free of protrusions, the first area at least partially defined by the lath face, the first end, the second and the first side. The rainscreen face includes a second area free of protrusions, the second area at least partially defined by the rainscreen face, the first end, the second end and the second side. In an alternate embodiment, the lath face does not include any protrusions and is undisrupted, smooth or flat.
In another aspect, the disclosure provides a method of installation including providing a building including a wall supported by a frame having a plurality of beams. A water resistant barrier is secured to the wall. Also provided is a first lath/rainscreen assembly including a sheet made of extruded material having a lath face and a rainscreen face; wherein the rainscreen face includes a plurality of protrusions. The lath face can optionally also include protrusions. The method further includes positioning the rainscreen face of the lath/rainscreen assembly against the water resistant barrier such that the protrusions contact the water resistant barrier and inserting a fastener through the sheet and the water resistant barrier and into the wall. The method may also include securing a facade or veneer (e.g., siding, stucco or masonry) to the lath face. In situations where stucco is applied to the lath face, the lath face may include a plurality of protrusions to provide a structure to grip the stucco.

DETAILED DESCRIPTION

FIGS. 1-6 collectively illustrate one embodiment of a lath/rainscreen assembly 10. In FIG. 1, the lath/rainscreen assembly 10 is operatively secured to a structure S having a frame F including beams B and a wall W sheathed in a water resistant barrier WRB and a weep screed WS positioned between the wall W and the water resistant barrier WRB. The water resistant barrier WRB and weep screed WS can be of any of the type known and used in building construction. The lath/rainscreen assembly 10 is positioned outboard of the water resistant barrier WRB and secured to the wall W of the structure S with mechanical fasteners (not shown) such as galvanized nails, staples, or the like. In some embodiments, a plurality of lath/rainscreen assemblies 10 are provided to be installed overlapping one another. In such embodiments, each lath/rainscreen assembly 10 can overlap an adjacent lath/rainscreen assembly 10 at least 1 inch. In other embodiments, the lath/rainscreen assemblies 10 overlap at least 1.5 inches.
As indicated by its name, each lath/rainscreen assembly 10 includes a sheet 12 having a lath face 14 a and a rainscreen face 14 b. The sheet 12 further includes first and second ends 16 a, 16 b as well as first and second sides 18 a, 18 b. The lath face 14 a is installed exterior with respect to the rainscreen face 14 b and supports a facade or veneer V (e.g., stucco, siding, masonry veneer including brick or stone, for example) applied the structure S. In some embodiments, a plurality of protrusions 20 a (only a select few of which are referenced for ease of illustration) extend from the sheet 12 and form at least part of the lath face 14 a. In one embodiment, the sheet 12 and protrusions 20 a collectively serve as a substrate for adhered stucco or other veneer V. In various embodiments, the plurality of protrusions 20 a are arranged to form a grid of linear intersecting channels 22, 24 oriented vertical, horizontal or diagonal with respect to the sheet 12 (only a few select channels are referenced for ease of illustration). In one illustrative embodiment, the intersecting channels 22, 24 each have a width of approximately ⅛ inch or more. The protrusions 20 a can take a variety for forms as will be discussed in greater detail below. In the present example, the protrusions 20 a include a stem 30 having a first end 32 and a second end 34. The first end 32 is secured to the sheet 12 and the second end 34 terminates at a head 36. The head 36 can be rectangular shaped, for example, and provides a structure onto which stucco can be applied for a more secure adherence or connection and provides a flat surface 38 on which the veneer V can be positioned. The flat surface 38 can be parallel to a plane defined by the sheet 12. The lath face 14 a forms voids between the sheet 12 and the protrusions 20 a, and the voids allow stucco to be received and retained therein. Because, in some embodiments, the protrusions 20 a are larger proximate their distal ends, the stucco has a more secure connection thereto. In the illustrated embodiment the stem 30 is tapered to have a greater diameter at the first end 32 as compared to the second end 34. As best seen in FIG. 6, each protrusion 20 a can have a height D1 and the sheet 12 can have a thickness D2. In one embodiment, for example, the height D1 could be approximately in a range of 0.25 to 3/16 inches and the sheet 12 could have a thickness D2 less than 0.25 inch. In one embodiment D2 is in a range of about 0.035 to about 0.045 inches. In various embodiments, the sheet 12 is solid, linear and has a uniform thickness D2. In an embodiment, the protrusions 20 a are spaced apart a distance D3 of approximately ⅕ inches. It is recognized that any dimensions could be different than the examples provided throughout the description because several factors, such as but limited to structural accommodations, manufacturing processes, and shipping accommodations, could affect the dimensions.
The rainscreen face 14 b of the sheet 12 can be similarly configured to the lath face 14 a and includes a plurality of protrusions 20 b (only a select few of which are referenced for ease of illustration) extending from the sheet 12. As with the protrusions 20 a, the protrusions 20 b collectively define a plurality of linear, intersecting channels 40, 42 that serve as an air gap and pathways for water to flow via gravity to the weep screen S (FIG. 4). The channels 40, 42 can be oriented vertically, horizontally or diagonally with respect to the sheet 12. The protrusions 20 b on the rainscreen face 14 b can be identically configured to the protrusions 20 a of the lath face 14 a or can differ in configuration and arrangement. Except as expressly stated, the lath face 14 a and the rainscreen face 14 b are preferably identically configured. In this way, there is no “front” and “back” side of the sheet 12 as both faces 14 a, 14 b are the interchangeable and this provides for easier installation.
As indicated above, it is envisioned that multiple lath/rainscreen assemblies 10 can be applied to the structure S and will be positioned on the structure S to overlap so that there are no gaps in coverage along the water resistant barrier WRB. To enable the lath/rainscreen assemblies 10 to be positioned in an overlapping configuration without bulging and creating the potential for moisture ingress, one end 16 a, 16 b of each face 14 a, 14 b of the sheet 12 includes an area 50 a, 50 b that does not include protrusions 20 a, 20 b. In addition, the areas 50 a, 50 b that do not include protrusions 20 a, 20 b can be rounded around building corners for securing to the next beam B. FIGS. 2A-7 collectively illustrate the lath face 14 a having a protrusion-free area 50 a at the first side 18 a and the rainscreen face 14 b has a protrusion free area 50 b at the second side 18 b of the sheet 12. In one example embodiment, each protrusion-free area has a width D4 of 1 inch or more. In another embodiment, the width D4 is 1.5 inches or more. In this way, as is depicted in FIG. 7, multiple lath/rainscreen assemblies 10 can be assembled to the structure S in an overlapping fashion to provide a plurality of lath/rainscreen assemblies 10 having a continuous arrangement of protrusions 20 a, 20 b on both the lath face 14 a and the rainscreen face 14 b. In various embodiments, the protrusions 20 a, 20 b are all vertically and horizontally aligned and arranged in rows. In one example, one sheet 12 is configured to span three conventionally-spaced beams B (i.e. the width of the sheet is about 33.5 inches wide). The present disclosure, however, is not intended to be limited to any specific dimensions. As indicated above, the lath face 14 a can optionally be identically configured as compared to the rainscreen face 14 b with the exception of one area free of protrusions 50 a is located proximate the first side 18 a of the sheet 12 and the second area free of protrusions 50 b is located proximate the second side 18 b of the sheet 12.
Optionally, the sheet 12 can include a plurality of apertures or perforations 52 (only a select few of which are referenced in FIG. 2A for ease of illustration) that extend through an entire thickness of the sheet 12 that can serve to allow moisture to pass from the water resistant barrier WRB, through the sheet 12. The apertures 52 can be positioned within one or more areas 50 a, 50 b and/or can also be positioned amongst the protrusions 20 a, 20 b, within channels 22, 24, 40, 42, as desired. In one example, one or more of areas 50 a, 50 b includes two rows of apertures 52 extending along a length of the respective area 50 a, 50 b. In one example, a row of apertures 52 arranged in linear fashion is provided within one or more of the channels 42. As indicated with like reference numbers, lath/rainscreen assembly 10′ is otherwise identical to lath/rainscreen assembly 10 disclosed herein.
As previously stated, the protrusions 20 a, 20 b can take a variety of forms. In one alternate embodiment illustrated in FIG. 8, each protrusion 120 a, 120 b includes a stem 130 a, 130 b and a head 136 a, 136 b. The stem 130 a, 130 b defines a plurality of channels 150 a, 150 b and peaks 152 a, 152 b (both generally referenced) defining approximately a 90 degree angle. The head 136 forms a flat engagement surface 138 a, 138 b. Each flat engagement surface 138 a, 138 b being parallel with respect to a plane defined by faces 14 a, 14 b of the sheet 12.
In another alternate embodiment illustrated in FIG. 9, each protrusion 220 a, 220 b includes a stem 230 a, 230 b and a head 236 a, 236 b. The stem 230 forms a plurality of channels 250 a. 250 b and peaks 252 a, 252 b each forming an edge that is parallel to a flat engagement surface 238 a, 238 b of the rectangular head 236 a, 236 b.
In FIG. 10, each protrusion 320 a, 320 b includes a stem 330 a, 330 b and a head 336 a, 336 b. Each stem 330 a, 330 b includes a first end 332 a, 332 b connected to the sheet 12 and a second end 334 a, 334 b connected to the head 336 a, 336 b. Each head 336 a, 336 b is generally square shaped and each stem 330 a, 330 b tapers such that the first end 332 a, 332 b has a greater width as compared to the second end 334 a, 334 b. Each head 336 a, 336 b forms a flat engagement surface 338 a, 338 b that is parallel with respect to a plane defined by the sheet 12.
In an additional embodiment illustrated in FIG. 11, each protrusion 420 a, 420 b includes a stem 430 a, 340 b and a head 436 a, 436 b. Each stem 430 a, 430 b can include a tapered portion 432 a, 432 b and a straight portion 434 a, 434 b interconnecting the tapered portion 432 a, 432 b and a head 436 a, 436 b. Each head 436 a, 436 b can be rectangular and include a flat engagement surface 438 a, 438 b. In some embodiments, the protrusion configurations of the disclosure provided on the lath/rainscreen assembly may not all be identical and may vary both with respect to other protrusions on the respective face and as compared to the opposing lath face or rainscreen face of the sheet.
It is recognized that other configurations of protrusions could be used and the examples provided herein should not be limiting.
Methods of installation the disclosed lath/rainscreen assemblies (e.g., lath/ rainscreen assemblies 10, 10′) can include providing the building B including the wall W supported by the frame F having the plurality of beams B as is generally depicted in FIG. 1. The method includes securing the water resistant barrier WRB to the wall W in any known manner. In addition one first lath/ rainscreen assembly 10, 10′ is provided, the lath/ rainscreen assembly 10, 10′ being any of the type disclosed herein. In one embodiment, the lath/ rainscreen assembly 10, 10′ includes the sheet 12 made of extruded material having a lath face 14 a and a rainscreen face 14 b. The lath face 14 a can optionally include the plurality of protrusions 20 a, 20 b and the rainscreen face 14 b does include a plurality of protrusions. The rainscreen face 14 b of the lath/ rainscreen assembly 10, 10′ is positioned against the water resistant barrier WRB such that the protrusions 20 a, 20 b contact the water resistant barrier WRB. For ease of installation, the lath face 14 a and the rainscreen face 14 b can be interchangeable (i.e. identical). In some embodiments, the sheet 12 preferably spans three 2×4 inch beams, spaced 16 inches on center (e.g., a width of the sheet 12 or dimension of ends 16 a, 16 b can be 33.5 inches). Because the sheet 12 is made of a flexible material, the sheet 12 can be wrapped around a corner of the building B, as needed. The method further includes inserting a fastener through the sheet 12 and the water resistant barrier WRB and into the wall W.
As indicated above, the first lath/rainscreen assembly (e.g., lath/ rainscreen assembly 10, 10′) can include an area free of protrusions 50 a, 50 b. With such a lath/rainscreen assembly, the method further includes the step of providing a second lath/rainscreen assembly (e.g., lath/ rainscreen assembly 10, 10′) and securing the second lath/ rainscreen assembly 10, 10′ on top of the area free of protrusions 50 a, 50 b.

The lath/rainscreen assembly 510 includes a sheet or strip 512 having a lath face 514 a and a rainscreen face 514 b. The rainscreen face 514 b includes a plurality of protrusions 520, which can be of any of the type disclosed herein or similar. The protrusions 520 (a select few of which are referenced for ease of illustration) are configured to be positioned against a water resistant barrier WRB secured to the wall W of the structure S. In one embodiment, each lath/rainscreen assembly 510 is secured along (i.e. is aligned with) one support beam B of the structure S and terminates at a vented metal edge E as is shown in FIG. 12. In some embodiments the lath/rainscreen assembly 510 has a width that is less than 33.5 inches, however, the disclosure is not intended to be limited to any particular dimensions. The lath/rainscreen assembly 510 can be secured to the water resistant barrier WRB with mechanical fasteners (not shown) including galvanized nails, staples or the like. The lath face 514 a is protrusion free (i.e. generally smooth or flat) and provides a surface over which siding or other veneer V can be secured in any known manner. The lath/rainscreen assembly 510 and protrusions 520, for example, can otherwise be identically configured similar to other disclosed lath/ rainscreen assemblies 10, 10′. Furthermore, the lath/rainscreen assembly 510 can be identically configured and installed to lath/ rainscreen assemblies 10, 10′, except as explicitly stated.
In some embodiments, methods of installing the disclosed lath/rainscreen assemblies 510 can include providing a building B including a wall W supported by a frame F having a plurality of beams B as is generally depicted in FIG. 12. The method includes securing the water resistant barrier WRB to the wall W in any known manner.

Siding panels V may extend between two or more lath/rainscreen assemblies 510 and can be secured to the lath/rainscreen assemblies 510 in any known manner.
Referring now also to FIG. 13, which illustrates an alternate lath/rainscreen assembly 610. The lath/rainscreen assembly 610 includes a sheet 612 having a lath face 614 a and a rainscreen face 614 b. The sheet 612 further includes first and second ends 616 a, 616 b as well as first and second sides 618 a, 618 b. The lath face 614 a is installed exterior with respect to the rainscreen face 614 b and supports the facade or veneer V (e.g., stucco, siding, masonry veneer including brick or stone, for example) applied the structure S in the same manner as described above with respect to other embodiments. Optionally, plurality of protrusions 620 a (only a select few of which are referenced for ease of illustration) extending from the sheet 12 and form a portion of the lath face 614. In one embodiment, the lath face 614 a and protrusions 620 a collectively serve as a substrate for the adhered stucco or other veneer V. In various embodiments, the plurality of protrusions 620 a are arranged to form a grid of linear intersecting channels 622, 624 oriented vertical, horizontal or diagonal with respect to the sheet 612 (only a few select channels are referenced for ease of illustration). In one illustrative embodiment, the intersecting channels 622, 624 each have a width of approximately ⅛ inch or more. The protrusions 620 a can take any of the forms disclosed herein.
The rainscreen face 614 b of the sheet 612 can be similarly configured to the lath face 614 a and includes a plurality of protrusions 620 b extending therefrom (only a select few of which are referenced for ease of illustration). As with the protrusions 620 a, the protrusions 620 b collectively define a plurality of linear, intersecting channels 640, 642 (a select few of which are referenced) that serve as an air gap and pathways for water to flow via gravity to the weep screen S (FIG. 4). The channels 640, 642 can be oriented vertically, horizontally or diagonally with respect to the sheet 612. The protrusions 620 b on the rainscreen face 614 b can be identically configured to the protrusions 620 a of the lath face 614 a. Except as expressly stated, the lath face 614 a and the rainscreen face 614 b are preferably identically configured.
As described above with respect to other embodiments, it is envisioned that multiple lath/rainscreen assemblies 610 can be applied to the structure S and will be positioned on the structure S to overlap so that there are no gaps in coverage along the water resistant barrier WRB. To enable the lath/rainscreen assemblies 610 to be positioned in an overlapping configuration without bulging and creating the potential for moisture ingress, one end 616 a, 616 b of each face 614 a, 614 b of the sheet 612 includes at least one area 650 a-c that does not include protrusions 620 a, 620 b. In addition, the areas 650 a-c that do not include protrusions 620 a, 620 b can be rounded around building corners for securing to the next beam B. In the illustrated example of FIG. 13, the lath face 614 a includes one area free of protrusions 650 a extending along the first side 618 a from the first end 616 a to the second end 616 a. The rainscreen face 614 b incudes one area free of protrusions 650 b extending along the second end 616 b from the first side 618 a to the second side 618 b. In addition, the rainscreen face 614 includes one area free of protrusions 650 c extending from the first end 616 a to the second end 616 b. In one example embodiment, each protrusion- free area 650 a, 650 b, 650 c has a width of 1 inch or more. In another embodiment, the width is 1.5 inches or more. In this way, multiple lath/rainscreen assemblies 610 can be assembled to the structure S overlapping at both the ends 616 a, 616 b and/or the sides 618 b, 618 b to provide a plurality of lath/rainscreen assemblies 610 having a continuous arrangement of protrusions 620 a, 620 b on both the lath face 614 a and the rainscreen face 614 b. In various embodiments, the protrusions 620 a, 620 b are all vertically and horizontally aligned and arranged in rows. The lath/rainscreen assembly 610 and methods of installation can otherwise be identical as compared to lath/rainscreen assemblies disclosed above.
The lath/rainscreen assemblies disclosed herein can be manufactured in a variety of ways. In one method, the process begins with extruding a solid sheet of extruded material, such as plastic. In one implementation, the sheet of extruded material is a plastic material having fire resistant characteristics or high impact poly styrene, for example. In one embodiment, the solid sheet of extruded material is 33.5 inches by 8-12 feet by 9/16 inches. Forming the lath/rainscreen assembly from a non-metal extruded material is beneficial in that it results in a product that is generally easier to work with, does not corrode or disrupt electrical or other signals, can be made of a fire retardant material and can be rolled-up for shipping and storage. It could also serve as a fire retardant. Once the sheet is extruded, the protrusions can optionally be formed via cutting with router blades to result in the desired protrusion configuration. In addition, apertures or perforations 52, such as those shown in FIG. 2B can be punched in the sheet, as desired.
It should be understood that various aspects disclosed herein may be combined in different combinations than the combinations specifically presented in the description and accompanying drawings. It should also be understood that, depending on the example, certain acts or events of any of the processes or methods described herein may be performed in a different sequence, may be added, merged, or left out altogether (e.g., all described acts or events may not be necessary to carry out the techniques).
