2. Description of the Related Art.
25 Walls of buildings not formed of reinforced concrete typically comprise of structural elements made of steel, concrete and like materials and have cladding components attached thereto. The cladding is generally finished with a decorative finish such as, wood boards, vinyl siding, hung pre-.cast decorative concrete siabs with varying textures or an exterior multi-layered system 30 terminating with an outer surface of a polymerJparticuEate decorative material. In the latter case, the exterior finish is also provided as a rain-fast surface.
Certain types of walls of buildings have an inner cavity between the outer cladding and an inner wall, typically consisting of a plasterboard material.
The 35 aforesaid cavity permits air movement with the outside atmosphere to provide an air pressure equalization chamber and moisture vent conduit for moisture infiltrating through the outer cladding. Notwithstanding the high degree of care during construction to provide a moisture-impermeable outer surface, over time by the action of wind and rain, temperature fluctuations etc, small cracks invariably are formed in this layer which allows moisture to enter the cavity and 5 into the interior of the building. Thusly the cavity must include a weep or vent hole to drain water from the cavity.
One cladding system presently in use which lacks an inner cavity, comprises of a multi-layer system of a typically 6-8 cm thick layer of insulating foam, such as, to (EPS) which is adhered to a wall sheathing with adhesives and mechanical fastening devices with large washered heads. Adhered to the outer surface of the foam layer is, typically, a reinforcing layer of two or more glass fiber meshes floated in a polymer-cement modified basecoat which is hand applied by a trowel. This basecoat protects the foam insulation layer from both physical damage and moisture ingress. To this outer basecoat layer is applied an exterior decorative layer of a polymer-particulate material, typically, sand dispersed in an acrylic polymer.
Such multi-layer cladding is formed, generally, from handle able, rectangular (EPS) panels of dimensions of 1.2 m. by 0.6 m. by 4 cm. being adhered to a wall substrate then the other materials being built up upon it.
The cEadding comprising an accumulation of such (EPS) panels is formed by them being cooperatively bonded in adjacent relationship as to provide insulation to the wall. Such construction lies well within the skill of plasterboard tradesmen.
In considering the desirability of a particular type of cladding system for use on a wall, regard must be given to the effect of wind pressure and rain on the outer wall surface.
With the absence of airflow between the outside atmosphere and' the atmosphere between the cladding and the substrate, significant air pressure differentials may result depending on the velocity of the wind acting on the wall system as well as the geometric design of the building and the resulting wind turbulences.
With large pressure differentials existing between the outside and inside of the building, significant moisture ingress through hair-line cracks and other unintentional openings such as around windows and doors can occur. In the 4o absence of a cavity in the wall, such moisture will reach and damage the inside surface of the wall of the building and with no means to escape, will begin the process of rot, mold and mildew formation.
Accordingly, a cavity within a clad wall system is preferred. Cladding systems which make every attempt to seal water from entering by way of a sealing membrane or other means, suffer the risk of water penetration over time.
Thus, while the aforementioned system may offer a reasonable esthetically pleasing exterior wall finish, such a wall often suffers from the effects of water damage hidden beneath its surface A system was required emerging from efforts to apply basic- moisture management principals arising from the 1990's "Leaky Condo" situation in British Columbia, Canada with good quality construction principals in an industry losing its skilled labour resources. The industry is currently using well-tested products that have been modified to overcome adverse criticism. An inherent problem io discovered in the conventional (EIFS) currently being used is the growth of mould and mildew resulting in rotting and often total failure of the underlying substrate and even the structural building components themselves.
When masonry walls were thick and the materials used were quite porous, their very mass absorbed the rainwater and later released it. Eventually, though, walls became thinner and something had to be done to prevent rain penetration. That could be either a face-sealed wall, which in a sense is a rainwater barrier in the form of vinyl or aluminum cladding on the-outside wall, or a cavity wall, which consists of one wall just to catch the rain and an adjacent cavity to serve as a moisture break. With open rain screen walls, which reflect current thinking in wall construction, the cladding constitutes the first line of defense. And then there is a second line of defense."i Current (EIFS) rely on the on-site assembly of a series of laminated layers of unlike building materials attached to the substrate with adhesives, cement based coatings, and fiber mesh reinforcement before the finished coat of stucco can be applied. The drying time between some layers can take up to 48 hours, weather permitting. Furthermore, any infiltration of water or moisture during the installation period can be trapped, beginning its destructive course even beforip the new job is completed. In this regard, even a careful professional installation cannot guarantee short term subsequent moisture protection to the structure.
SUMMARY OF THE INVENTION
Thi$- -nvention relates to the design and installation of a- wall cladding syster>1 which comprises an assembly of engineered cementitious coated (EPS) StuccoBase Panels mechanically fastened with screws or similar devices to an existing wall surface.
4o The invention is an innovative departure from conventional construction methods. The System is not only in the product, but also in the process itself.
1 Chown, G.A., W.C. Brown and G.F. Poirier Evolution of Wall Design for Controlling Rain Penetration Construction Technology Updates, No. 9.
Ottawa: National Research Council of Canada, Institute for Research in Construction 1997 Icon uses proprietary extrusion technology to produce an exterior cementitious cladding StuccoBase Panel for use in the residential and commercial construction industry. The product is factory manufactured by extruding a 1 cm thick polymerized concrete coating onto a pre-shaped (EPS) core material.
The StuccoBase Panels are installed in one step directly onto the substrate regardless of the weather conditions.
The joints are filled with a quick-drying polymerized mortar and the surface is io immediately ready for a durable finish coating.
Typically, the specific use is in the exterior wall cladding of a building which is characteristically finished with a synthetic stucco material, commonly known to the (EIFS) trade It is the intent of the present invention to provide an improved cladding system for the wall of a building which can be readily constructed on-site and which provides air pressure equalization with the outside air.
It is a further intended to provide a plurality of interconnecting air pressure and moisture vent channels which not only equalize pressure, but also permit the drainage of infiltrated moisture.
Further it is to provide a cladding system manufactured in a controlled environment resulting in a level of superior and consistent quality that incomparably surpasses that of any on-site assembly which is required by corrventional (EIFS).
The moisture management principals of the cladding system meet the 3o requirements of the (OAA) Ontario Associates of Architects Rain Penetration Control Practice Guide for exterior wall design without the addition of a secondary drainage mat.
The system is a continuous-sealed system that does not rely on the face-sealed system of the currently used in (EIFS), but rather on the secondary line of defense of engineered drainage channels and ventilation cavities built into the system that dissipate any moisture infiltration once installed.
Installation of the system does not require skilled specialty workers. The speed 4o and ease of the installation substantially reduces the construction timeline, which translates into a more efficient building project, which further translates into cost-savings for the builder.
The integrity of the system is not only in the discernible attributes of the design, but also w'rth the durability of the product. The system is idealty engineered from both sides. The potymerized cementitious surface is exceptronatty wett-suited for finish coatings and the underside is designed with unique moisture management principals integrated into its inherent structure providing moisture drainage by the action of gravity and evaporation of moisture through air circulation between the cladding and substrate.
Conventional flashing practices and caulking are applied at the unions with other building components and the cladding.
The invention provides in a further broad aspect, an improved cladding of the io walh of a bu'tk#irtg, said cladding system comprising a plurafity- of StttccoBase Panets in an adjacent relationship as to provide a continuom seated-installation and said StuccoBase Panels being so shaped as to provide said cladding system with a plurality of interconnecting air pressure equalization and vent channels.
By " adjacent relationship" it is meant that the cladding StuccoBase Panels are installed one adjacent to another atop the outer surface of a constructed wall in q pattern resembling brick-laying where the vertical end joints are staggered relative to the course of StuccoBase Panels and their edges in the previous course, as to create a continuous-seal layer to the exterior wall surface.
The term "cladding with a plurality of interconnecting air pressure equalization and moisture vent channels", is meant cladding having a plurality of interconnecting channels throughout a desired area of the cladding. It is not meant to include a system having parallel vertically aligned channels which intersect solely with a single, horizontally aligned channel extending across the width of the cladding, particularly, at a lower part thereof.
The StuccoBase Panels are shaped such that when they are part of the wall they produce, in consequence of adjacent relationship with other StuccoBase Panels, a plurality of channels which inter-connect with each other and via a lower perforated flashing member and an upper protected perforated flashing member with the outsideatmosphere. The plurality of channels may extend substantially across the full area-of the cladding. The wall may be provided with intervening structures such as doors or windows which may abut, directly or indirectly, the StuccoBase Panels according to the invention, but which wall still satisfies the object of the invention. With the staggered vertical edge joints of the StuccoBase Panels resulting in the non-alignment of the vertical drainage channels the StuccoBase Panels are so shaRed as to remedy the consequential btockage of water and air flow between courses.
The design of the StuccoBase Panel provides a portion defining a channel edge running along the full length of the back of the StuccoBase Panel which interconnects with the vertical beveled channels to provide interconnecting air pressure equalization, vent and drainage channels.
Each of the cladding StuccoBase Panels may be of any suitable shape and dimension. Preferably, the StuccoBase Panel is roughly a 1.2 m×0.4 m×5.0 cm rectangular shaped member.
The StuccoBase- Panels may be so shaped as to provide suitable joint configuration and dimension to permit satisfactory surface area for mortar joint material. In one embodiment, the StuccoBase Panel coating has radiuses edge portions along 2 edges. The radiuses portion may be defined by the edge io surface as a quadrant arcuate form, semi-square form or 45 degree angled form.
Preferably, the radius extends the whole length of each of the 't.2 m long sides.
The cladding system has preferably an airtight inner barrier either adhered to the substrate or disposed between the substrate and the cladding StuccoBase Panels.
One very important consideration that must be given to the construction of wall cladd.ittg, particularly, cladding of commerciat and industrial buildings, is that concerning fire prevention and retardation.
Prior to the commercial introduction to the trade of a novel wall cladding for use in a commercial or industrial building, the wall materials and constructed wall must undergQ extensive, standard fire testing: In one such test, a-flame is played onto the back of the (EPS) isatative cladding to determine whettrerthe resultant system meets the regulatory requirements.
It is known that (EPS) melts at 1700 degrees Celsius to a viscous, but rriobile fluid, thus, in the wall cladding structure according to the invention, it is reasonable to expect that, notwithstanding the fire retardancy of the-con-ventional (EPS), under certain high temperature conditions the (EPS) may melt and exit tq and through the lower perforated starting flashing according to the invention.
Further, it is realized that the cladding material itself can detach from the building and fall onto neighboring structures or people in the event of a fire.
Accordingly, to-red<uce the possibility of the cladding detaching in this manner tho invention provides in a further aspect, wall cladding of a building as hereinabove defined wherein the coating itself is mechanically fastened to the substrate with the fastening device securely embedded in typically 1.2 to 2.5 cm of the typically 1 cm thick cementitious material. This provides a stable non-moving cladding surface which would stand off the substrate in the event of liquefaction of the (EPS) portion.
In addition to the above consideration the formulation of the cladding coating is non-combustible for such installations and thus acts as an enhanced flame-spread protection and provides improved fire safety.
In its simplest form, this aspect of the invention comprises a non-combustible cementitious cladding coating mechanically fastened to the substrate with an (EPS) spacing material beneath with sufficient channels to properly achieve water drainage and air pressure equalization.
DESCRIPTION OF THE DRAWINGS

Figure 1 shows a side view of the installed wall cladding system Figure 2 shows and end view of the cladding StuccoBase Panel Figure 3 shows the top isometric view of a cladding StuccoBase Panel Figure 4 shouussa back isometric view of united StuccoBase Pan.els.
Figure 5 shows a cEose-up detait side view of section of instaRed cla"ng system Figure 6 shows a bottom isometric view of the wall cladding system 2o Figure 7 shows a top isometric view of the installed wall cladding system Figure 8 shows a front isometric view of the installed wall cladding system Figure 9 shows a top isometric view of the installed cladding system at an inner corner Figure 10 shows a top isometric view of the installed cladding system at an outer corner As shown in Figure 1, the wall cladding system comprises a wall stud member (12) onto which is attached a sheathing material such as (OSB) ****pressed board (13) covered in a vapor barrier such as tar paper or TyvecoD (14). The StuccoBase Panels (Figure 2 and figure 3) are attached to the exposed vapor barrier surface by means of fastening devices (17) preferably but not limited to deck screws, or Tapcon screws.
Figure 2 shows the preferred embodiments of the StuccoBase Panel comprising of: a pre- shaped (EPS) base (1) having channels cut preferably, but not limited to, full length into the upper surface which serve as reinforcing ribs (5) when the cementitious coating (9) is applied during the manufacturing process. These channels are typically, but not limited to, the dimensions of 0.635 cm wide by 0.635 cm deep.
Two additional channels (6) are cut into the same surface of the (EPS) cut s preferably, but not limited to, full length into the upper surface which serves as mechanical fastening ribs typically, but not limited to, the dimensions of 1.9 cm wide by 0.95 cm deep. It is into the width center of these ribs that a fastening device (17) is used. The said fastening device is located along points the length of the StuccoBase Panel such that it penetrates through the (EPS) back surface io feature (3) (figure 1 and figure 4) resulting in a seal (15) being formed between the vapor barrier (14) and the (EPS) (1).
The back or lower surface of the (EPS) materiaf has channels cut along and across the StuccoBase Panel's length and width. Channels (2) are cut along the length of the (EPS) (1) creating voids (evaporation cavities) allowing for air and 15 water movement when the StuccoBase Panels are installed. These channels can be of differing shapes with the sides of the channels being at 90 (degrees) to the base of the channel or other angles. The preferred, although not limited to, shapes are beveled channels running the length of the panel and square edged channels running across the width of the panel. The beveled shape of the 20 channels (4) draws flowing or dripping water from the substrate towards the (EPS) material core. The resulting dovetail features (3) serve four functions:
a) They provide a series of "legs" which support the StuccoBase Panel away from the substrate b) They are compressible allowing for adjustment of the StuccoBase Panel edges relative to one another when installed by adjusting the tightness of the fastening screws (17).
c) They serve as scoops to draw downward flowing or dripping water from the substrate (22) (figure 5) d) They create a seal (15) (Figure 5) around the fastening screws between the substrate and the StuccoBase Panel.
Intersecting the channels (2) are channels (7) (figure 4) cut across the width of the back (EPS) surface of the StuccoBase Panel. Ideally, although not limited to lo being cut with square sides as opposed to beveled sides. These serve as drainage channels to flowing water as well as ventilation channels for air circulation by convection in the finished wall system. When the StuccoBase Panels are installed horizontally, the bevel (8) on each long edge of the (EPS) back surface, allow the flow of water (21) along the edges of the StuccoBase is Panel to the next closest drainage channel (7).
The top surface of the StuccoBase Panel is a cementitious layer (9) which is typically, but not limited to 0.95 cm thick which extends across the width of the (EPS) leaving typically but not limited to 1.mm to 2. mm (EPS) extending beyond the coating (19). This serves the function of installing the StuccoBase Panels 2o atop one another with the (EPS) edge of one StuccoBase Panel fully contacting the (EPS) edge of the adjoining StuccoBase Panel. The compressive quality of the (EFTS) prevents cracking of the cladding system joints during freeze thaW
cycles of expansion and contraction of the system components. The edge of this coating is shaped in a radius (10) to provide a larger surface area onto which the mortar (16) can adhere to. This radius can be of varying shapes to serve the same purpose such as but not limited to, straight beveled, wavy, notched and concave.
StuccoBase Panels are installed horizontally onto a wall as shown in Figure 7 and Figure 8 comprising of wall studs (12) sheathing (13) and a vapor barrier such as Tyvek or tar paper (14). The drainage channels (7) run vertically and the evaporation cavity channels (2) run horizontally. The vertical StuccoBase Panel joints (20) are staggered with a 2mm gap between the StuccoBase Panel io end joints allowing for mortar (16) penetration. The first course of StuccoBase Panel is installed on a starting strip of perforated plastic or rust-proof metal flashing (18) as shown in Figure 6. This flashing strip protects the lower edge of the (EPS) (1) from damage and deterioration but allows for air and water transmission through the perforations. The perforations in the flashing are small enough to prevent insects from entering, and are numerous enough to allow for drainage and ventilation.
All joints between the StuccoBase Panel and countersunk screw heads are filled with a polymerized mortar (16) or other suitable bonding material known to the art of adhesion. After installation the surface of the StuccoBase Panel and joint mortar (the cladding surface) is coated with a finish coating, preferably but not limited to Synthetic Flexible Stucco (11) to render a uniform desired finished surface.
When installing the cladding system at an inner corner (Figure 9), The StuccoBase Panel of one wall surface (27) are installed with their ends directed towards the adjacent wall surface, (28) leaving a gap (23) of 0.6 cm to 1 cm to allow for movement of the building structure independent of the cementitious coating (9) to prevent cracking of the cladding system at the corner due to settling of the building structure. The StuccoBase Panels applied to the adjacent wall (28) are fastened with their end surfaces touching the previously instailed StuccoBase Panels (27). A flexible caulking compound (24) previously known to the art is applied to the joint between the cladding wall surfaces where they form io the inside corner. This installation procedure will provide the cladding system with a "live joint" at the inside corner allowing for movement without compromising the integrity of the system as a whole.
When installing exterior corners (Figure 10), a portion of the (EPS) is removed from the back edge of one StuccoBase Panel equidistant from the end of the StuccoBase Panel as the thickness of a StuccoBase Panel which will be installed against it, and to a depth from the back towards the front as to be even with the cementitious coating at the point it unites with the (EPS) base (25). This configuration provides an outer corner edge of cementitious material, which when finished with a mortar coating (16) results in a solid exterior corner structure suitable for application of a finish material thereon.
The orientation of the resulting overlap corner joint is alternated with each course of StuccoBase Panels being installed (26). Fastening screws (17) are used back from the outer corner edge of the StuccoBase Panels so that they penetrate the substrate and not the overlapped StuccoBase Panel. Care must be taken at this point to ensure the fastening device is in fact penetrating the substrate.
At all other termination points on the building where the cladding system adjoins non-cladding elements such as windows, doors, roofs, etc., flashing, caulking 5 and other moisture protection devices are used in accordance with standard building construction practices known to the art.
25 Walls of buildings not formed of reinforced concrete typically comprise of structural elements made of steel, concrete and like materials and have cladding components attached thereto. The cladding is generally finished with a decorative finish such as, wood boards, vinyl siding, hung pre-.cast decorative concrete siabs with varying textures or an exterior multi-layered system 30 terminating with an outer surface of a polymerJparticuEate decorative material. In the latter case, the exterior finish is also provided as a rain-fast surface.
Certain types of walls of buildings have an inner cavity between the outer cladding and an inner wall, typically consisting of a plasterboard material.
The 35 aforesaid cavity permits air movement with the outside atmosphere to provide an air pressure equalization chamber and moisture vent conduit for moisture infiltrating through the outer cladding. Notwithstanding the high degree of care during construction to provide a moisture-impermeable outer surface, over time by the action of wind and rain, temperature fluctuations etc, small cracks invariably are formed in this layer which allows moisture to enter the cavity and 5 into the interior of the building. Thusly the cavity must include a weep or vent hole to drain water from the cavity.
One cladding system presently in use which lacks an inner cavity, comprises of a multi-layer system of a typically 6-8 cm thick layer of insulating foam, such as, to (EPS) which is adhered to a wall sheathing with adhesives and mechanical fastening devices with large washered heads. Adhered to the outer surface of the foam layer is, typically, a reinforcing layer of two or more glass fiber meshes floated in a polymer-cement modified basecoat which is hand applied by a trowel. This basecoat protects the foam insulation layer from both physical damage and moisture ingress. To this outer basecoat layer is applied an exterior decorative layer of a polymer-particulate material, typically, sand dispersed in an acrylic polymer.
Such multi-layer cladding is formed, generally, from handle able, rectangular (EPS) panels of dimensions of 1.2 m. by 0.6 m. by 4 cm. being adhered to a wall substrate then the other materials being built up upon it.
The cEadding comprising an accumulation of such (EPS) panels is formed by them being cooperatively bonded in adjacent relationship as to provide insulation to the wall. Such construction lies well within the skill of plasterboard tradesmen.
In considering the desirability of a particular type of cladding system for use on a wall, regard must be given to the effect of wind pressure and rain on the outer wall surface.
With the absence of airflow between the outside atmosphere and' the atmosphere between the cladding and the substrate, significant air pressure differentials may result depending on the velocity of the wind acting on the wall system as well as the geometric design of the building and the resulting wind turbulences.
With large pressure differentials existing between the outside and inside of the building, significant moisture ingress through hair-line cracks and other unintentional openings such as around windows and doors can occur. In the 4o absence of a cavity in the wall, such moisture will reach and damage the inside surface of the wall of the building and with no means to escape, will begin the process of rot, mold and mildew formation.
Accordingly, a cavity within a clad wall system is preferred. Cladding systems which make every attempt to seal water from entering by way of a sealing membrane or other means, suffer the risk of water penetration over time.
Thus, while the aforementioned system may offer a reasonable esthetically pleasing exterior wall finish, such a wall often suffers from the effects of water damage hidden beneath its surface A system was required emerging from efforts to apply basic- moisture management principals arising from the 1990's "Leaky Condo" situation in British Columbia, Canada with good quality construction principals in an industry losing its skilled labour resources. The industry is currently using well-tested products that have been modified to overcome adverse criticism. An inherent problem io discovered in the conventional (EIFS) currently being used is the growth of mould and mildew resulting in rotting and often total failure of the underlying substrate and even the structural building components themselves.
When masonry walls were thick and the materials used were quite porous, their very mass absorbed the rainwater and later released it. Eventually, though, walls became thinner and something had to be done to prevent rain penetration. That could be either a face-sealed wall, which in a sense is a rainwater barrier in the form of vinyl or aluminum cladding on the-outside wall, or a cavity wall, which consists of one wall just to catch the rain and an adjacent cavity to serve as a moisture break. With open rain screen walls, which reflect current thinking in wall construction, the cladding constitutes the first line of defense. And then there is a second line of defense."i Current (EIFS) rely on the on-site assembly of a series of laminated layers of unlike building materials attached to the substrate with adhesives, cement based coatings, and fiber mesh reinforcement before the finished coat of stucco can be applied. The drying time between some layers can take up to 48 hours, weather permitting. Furthermore, any infiltration of water or moisture during the installation period can be trapped, beginning its destructive course even beforip the new job is completed. In this regard, even a careful professional installation cannot guarantee short term subsequent moisture protection to the structure.
SUMMARY OF THE INVENTION
Thi$- -nvention relates to the design and installation of a- wall cladding syster>1 which comprises an assembly of engineered cementitious coated (EPS) StuccoBase Panels mechanically fastened with screws or similar devices to an existing wall surface.
4o The invention is an innovative departure from conventional construction methods. The System is not only in the product, but also in the process itself.
1 Chown, G.A., W.C. Brown and G.F. Poirier Evolution of Wall Design for Controlling Rain Penetration Construction Technology Updates, No. 9.
Ottawa: National Research Council of Canada, Institute for Research in Construction 1997 Icon uses proprietary extrusion technology to produce an exterior cementitious cladding StuccoBase Panel for use in the residential and commercial construction industry. The product is factory manufactured by extruding a 1 cm thick polymerized concrete coating onto a pre-shaped (EPS) core material.
The StuccoBase Panels are installed in one step directly onto the substrate regardless of the weather conditions.
The joints are filled with a quick-drying polymerized mortar and the surface is io immediately ready for a durable finish coating.
Typically, the specific use is in the exterior wall cladding of a building which is characteristically finished with a synthetic stucco material, commonly known to the (EIFS) trade It is the intent of the present invention to provide an improved cladding system for the wall of a building which can be readily constructed on-site and which provides air pressure equalization with the outside air.
It is a further intended to provide a plurality of interconnecting air pressure and moisture vent channels which not only equalize pressure, but also permit the drainage of infiltrated moisture.
Further it is to provide a cladding system manufactured in a controlled environment resulting in a level of superior and consistent quality that incomparably surpasses that of any on-site assembly which is required by corrventional (EIFS).
The moisture management principals of the cladding system meet the 3o requirements of the (OAA) Ontario Associates of Architects Rain Penetration Control Practice Guide for exterior wall design without the addition of a secondary drainage mat.
The system is a continuous-sealed system that does not rely on the face-sealed system of the currently used in (EIFS), but rather on the secondary line of defense of engineered drainage channels and ventilation cavities built into the system that dissipate any moisture infiltration once installed.
Installation of the system does not require skilled specialty workers. The speed 4o and ease of the installation substantially reduces the construction timeline, which translates into a more efficient building project, which further translates into cost-savings for the builder.
The integrity of the system is not only in the discernible attributes of the design, but also w'rth the durability of the product. The system is idealty engineered from both sides. The potymerized cementitious surface is exceptronatty wett-suited for finish coatings and the underside is designed with unique moisture management principals integrated into its inherent structure providing moisture drainage by the action of gravity and evaporation of moisture through air circulation between the cladding and substrate.
Conventional flashing practices and caulking are applied at the unions with other building components and the cladding.
The invention provides in a further broad aspect, an improved cladding of the io walh of a bu'tk#irtg, said cladding system comprising a plurafity- of StttccoBase Panets in an adjacent relationship as to provide a continuom seated-installation and said StuccoBase Panels being so shaped as to provide said cladding system with a plurality of interconnecting air pressure equalization and vent channels.
By " adjacent relationship" it is meant that the cladding StuccoBase Panels are installed one adjacent to another atop the outer surface of a constructed wall in q pattern resembling brick-laying where the vertical end joints are staggered relative to the course of StuccoBase Panels and their edges in the previous course, as to create a continuous-seal layer to the exterior wall surface.
The term "cladding with a plurality of interconnecting air pressure equalization and moisture vent channels", is meant cladding having a plurality of interconnecting channels throughout a desired area of the cladding. It is not meant to include a system having parallel vertically aligned channels which intersect solely with a single, horizontally aligned channel extending across the width of the cladding, particularly, at a lower part thereof.
The StuccoBase Panels are shaped such that when they are part of the wall they produce, in consequence of adjacent relationship with other StuccoBase Panels, a plurality of channels which inter-connect with each other and via a lower perforated flashing member and an upper protected perforated flashing member with the outsideatmosphere. The plurality of channels may extend substantially across the full area-of the cladding. The wall may be provided with intervening structures such as doors or windows which may abut, directly or indirectly, the StuccoBase Panels according to the invention, but which wall still satisfies the object of the invention. With the staggered vertical edge joints of the StuccoBase Panels resulting in the non-alignment of the vertical drainage channels the StuccoBase Panels are so shaRed as to remedy the consequential btockage of water and air flow between courses.
The design of the StuccoBase Panel provides a portion defining a channel edge running along the full length of the back of the StuccoBase Panel which interconnects with the vertical beveled channels to provide interconnecting air pressure equalization, vent and drainage channels.
Each of the cladding StuccoBase Panels may be of any suitable shape and dimension. Preferably, the StuccoBase Panel is roughly a 1.2 m×0.4 m×5.0 cm rectangular shaped member.
The StuccoBase- Panels may be so shaped as to provide suitable joint configuration and dimension to permit satisfactory surface area for mortar joint material. In one embodiment, the StuccoBase Panel coating has radiuses edge portions along 2 edges. The radiuses portion may be defined by the edge io surface as a quadrant arcuate form, semi-square form or 45 degree angled form.
Preferably, the radius extends the whole length of each of the 't.2 m long sides.
The cladding system has preferably an airtight inner barrier either adhered to the substrate or disposed between the substrate and the cladding StuccoBase Panels.
One very important consideration that must be given to the construction of wall cladd.ittg, particularly, cladding of commerciat and industrial buildings, is that concerning fire prevention and retardation.
Prior to the commercial introduction to the trade of a novel wall cladding for use in a commercial or industrial building, the wall materials and constructed wall must undergQ extensive, standard fire testing: In one such test, a-flame is played onto the back of the (EPS) isatative cladding to determine whettrerthe resultant system meets the regulatory requirements.
It is known that (EPS) melts at 1700 degrees Celsius to a viscous, but rriobile fluid, thus, in the wall cladding structure according to the invention, it is reasonable to expect that, notwithstanding the fire retardancy of the-con-ventional (EPS), under certain high temperature conditions the (EPS) may melt and exit tq and through the lower perforated starting flashing according to the invention.
Further, it is realized that the cladding material itself can detach from the building and fall onto neighboring structures or people in the event of a fire.
Accordingly, to-red<uce the possibility of the cladding detaching in this manner tho invention provides in a further aspect, wall cladding of a building as hereinabove defined wherein the coating itself is mechanically fastened to the substrate with the fastening device securely embedded in typically 1.2 to 2.5 cm of the typically 1 cm thick cementitious material. This provides a stable non-moving cladding surface which would stand off the substrate in the event of liquefaction of the (EPS) portion.
In addition to the above consideration the formulation of the cladding coating is non-combustible for such installations and thus acts as an enhanced flame-spread protection and provides improved fire safety.
In its simplest form, this aspect of the invention comprises a non-combustible cementitious cladding coating mechanically fastened to the substrate with an (EPS) spacing material beneath with sufficient channels to properly achieve water drainage and air pressure equalization.
DESCRIPTION OF THE DRAWINGS
to Thus, in order that the invention may be better understood, preferred embodiments will now be described, by way of example only, with reference to the accompanying drawings wherein:
Figure 1 shows a side view of the installed wall cladding system Figure 2 shows and end view of the cladding StuccoBase Panel Figure 3 shows the top isometric view of a cladding StuccoBase Panel Figure 4 shouussa back isometric view of united StuccoBase Pan.els.
Figure 5 shows a cEose-up detait side view of section of instaRed cla"ng system Figure 6 shows a bottom isometric view of the wall cladding system 2o Figure 7 shows a top isometric view of the installed wall cladding system Figure 8 shows a front isometric view of the installed wall cladding system Figure 9 shows a top isometric view of the installed cladding system at an inner corner Figure 10 shows a top isometric view of the installed cladding system at an outer corner As shown in Figure 1, the wall cladding system comprises a wall stud member (12) onto which is attached a sheathing material such as (OSB) ****pressed board (13) covered in a vapor barrier such as tar paper or TyvecoD (14). The StuccoBase Panels (Figure 2 and figure 3) are attached to the exposed vapor barrier surface by means of fastening devices (17) preferably but not limited to deck screws, or Tapcon screws.
Figure 2 shows the preferred embodiments of the StuccoBase Panel comprising of: a pre- shaped (EPS) base (1) having channels cut preferably, but not limited to, full length into the upper surface which serve as reinforcing ribs (5) when the cementitious coating (9) is applied during the manufacturing process. These channels are typically, but not limited to, the dimensions of 0.635 cm wide by 0.635 cm deep.
Two additional channels (6) are cut into the same surface of the (EPS) cut s preferably, but not limited to, full length into the upper surface which serves as mechanical fastening ribs typically, but not limited to, the dimensions of 1.9 cm wide by 0.95 cm deep. It is into the width center of these ribs that a fastening device (17) is used. The said fastening device is located along points the length of the StuccoBase Panel such that it penetrates through the (EPS) back surface io feature (3) (figure 1 and figure 4) resulting in a seal (15) being formed between the vapor barrier (14) and the (EPS) (1).
The back or lower surface of the (EPS) materiaf has channels cut along and across the StuccoBase Panel's length and width. Channels (2) are cut along the length of the (EPS) (1) creating voids (evaporation cavities) allowing for air and 15 water movement when the StuccoBase Panels are installed. These channels can be of differing shapes with the sides of the channels being at 90 (degrees) to the base of the channel or other angles. The preferred, although not limited to, shapes are beveled channels running the length of the panel and square edged channels running across the width of the panel. The beveled shape of the 20 channels (4) draws flowing or dripping water from the substrate towards the (EPS) material core. The resulting dovetail features (3) serve four functions:
a) They provide a series of "legs" which support the StuccoBase Panel away from the substrate b) They are compressible allowing for adjustment of the StuccoBase Panel edges relative to one another when installed by adjusting the tightness of the fastening screws (17).
c) They serve as scoops to draw downward flowing or dripping water from the substrate (22) (figure 5) d) They create a seal (15) (Figure 5) around the fastening screws between the substrate and the StuccoBase Panel.
Intersecting the channels (2) are channels (7) (figure 4) cut across the width of the back (EPS) surface of the StuccoBase Panel. Ideally, although not limited to lo being cut with square sides as opposed to beveled sides. These serve as drainage channels to flowing water as well as ventilation channels for air circulation by convection in the finished wall system. When the StuccoBase Panels are installed horizontally, the bevel (8) on each long edge of the (EPS) back surface, allow the flow of water (21) along the edges of the StuccoBase is Panel to the next closest drainage channel (7).
The top surface of the StuccoBase Panel is a cementitious layer (9) which is typically, but not limited to 0.95 cm thick which extends across the width of the (EPS) leaving typically but not limited to 1.mm to 2. mm (EPS) extending beyond the coating (19). This serves the function of installing the StuccoBase Panels 2o atop one another with the (EPS) edge of one StuccoBase Panel fully contacting the (EPS) edge of the adjoining StuccoBase Panel. The compressive quality of the (EFTS) prevents cracking of the cladding system joints during freeze thaW
cycles of expansion and contraction of the system components. The edge of this coating is shaped in a radius (10) to provide a larger surface area onto which the mortar (16) can adhere to. This radius can be of varying shapes to serve the same purpose such as but not limited to, straight beveled, wavy, notched and concave.
StuccoBase Panels are installed horizontally onto a wall as shown in Figure 7 and Figure 8 comprising of wall studs (12) sheathing (13) and a vapor barrier such as Tyvek or tar paper (14). The drainage channels (7) run vertically and the evaporation cavity channels (2) run horizontally. The vertical StuccoBase Panel joints (20) are staggered with a 2mm gap between the StuccoBase Panel io end joints allowing for mortar (16) penetration. The first course of StuccoBase Panel is installed on a starting strip of perforated plastic or rust-proof metal flashing (18) as shown in Figure 6. This flashing strip protects the lower edge of the (EPS) (1) from damage and deterioration but allows for air and water transmission through the perforations. The perforations in the flashing are small enough to prevent insects from entering, and are numerous enough to allow for drainage and ventilation.
All joints between the StuccoBase Panel and countersunk screw heads are filled with a polymerized mortar (16) or other suitable bonding material known to the art of adhesion. After installation the surface of the StuccoBase Panel and joint mortar (the cladding surface) is coated with a finish coating, preferably but not limited to Synthetic Flexible Stucco (11) to render a uniform desired finished surface.
When installing the cladding system at an inner corner (Figure 9), The StuccoBase Panel of one wall surface (27) are installed with their ends directed towards the adjacent wall surface, (28) leaving a gap (23) of 0.6 cm to 1 cm to allow for movement of the building structure independent of the cementitious coating (9) to prevent cracking of the cladding system at the corner due to settling of the building structure. The StuccoBase Panels applied to the adjacent wall (28) are fastened with their end surfaces touching the previously instailed StuccoBase Panels (27). A flexible caulking compound (24) previously known to the art is applied to the joint between the cladding wall surfaces where they form io the inside corner. This installation procedure will provide the cladding system with a "live joint" at the inside corner allowing for movement without compromising the integrity of the system as a whole.
When installing exterior corners (Figure 10), a portion of the (EPS) is removed from the back edge of one StuccoBase Panel equidistant from the end of the StuccoBase Panel as the thickness of a StuccoBase Panel which will be installed against it, and to a depth from the back towards the front as to be even with the cementitious coating at the point it unites with the (EPS) base (25). This configuration provides an outer corner edge of cementitious material, which when finished with a mortar coating (16) results in a solid exterior corner structure suitable for application of a finish material thereon.
The orientation of the resulting overlap corner joint is alternated with each course of StuccoBase Panels being installed (26). Fastening screws (17) are used back from the outer corner edge of the StuccoBase Panels so that they penetrate the substrate and not the overlapped StuccoBase Panel. Care must be taken at this point to ensure the fastening device is in fact penetrating the substrate.
At all other termination points on the building where the cladding system adjoins non-cladding elements such as windows, doors, roofs, etc., flashing, caulking 5 and other moisture protection devices are used in accordance with standard building construction practices known to the art.
