Abstract
A coating for an exterior surface contains acrylic resin, silica sand and sufficient reinforcing fibers to provide surface coverage of fibers of 5- 50%. Different acrylic resins may be mixed to vary the resilience and hardness of the coating. Exterior panels are prepared using the coating by spraying the coating on a foam sheet. Designs, such as grout lines resembling bricks, uneven rocks or blocks are made by first applying the design to the foam and then rolling or spraying the coating over the imprinted foam. Designs may be applied using heat or solvent or other techniques. The panels made are fastened to the exterior surface of a structure using fasteners or adhesives. The coating may be used as the adhesive and may also be used to caulk between adjacent panels.
Description
1 "DECORATIVE EXTERIOR WALL PANEL"
2
3 FIELD OF THE INVENTION
4 Embodiments of the invention relate to exterior wall panels and, more particularly, to aesthetically pleasing panels for installation on an exterior 6 wall of a static structure, such as a building.
9 Structures, such as commercial and residential buildings, are typically finished on an exterior surface with an aesthetic, decorative finish.
11 Traditionally, the exterior finishes have been natural materials, such as rock, and 12 manmade materials, such as brick. Typically, however such materials are very 13 expensive and require specially trained artisans and installers to properly 14 prepare and install such materials.
Veneer-type panels using natural and brick materials have been 16 created however these type of exterior panels are still relatively expensive as 17 they are labor intensive to manufacture.
18 In order to reduce the cost and labor involved while maintaining the 19 aesthetics of a rock or brick finish and the insulating properties associated therewith, it is known to provide exterior surface materials which are made of a 21 variety of composite materials and the like.
22 One such technique is to provide a multilayer finish to a wall 23 comprising an inner styrofoam layer covered with a fiberglass wire mesh and 24 fastened, using fasteners or adhesives, to the wall's exterior surface. The fiberglass wire mesh is coated with a top coat which adheres to the mesh 26 followed by a base coat and a finish coat. One such material used as the top and 1 base coat is a flexible joint compound such as Sto Gold FiIIT"~ available from Sto 2 Corp. of Atlanta Georgia USA 30331. The finish coat is typically a waterproof 3 coating such as Sto Gold CoatT"~ also available from Sto Corp. of Atlanta 4 Georgia USA 30331. The joint compound is typically applied using a trowel and the finish coat is applied using a roller. Skill is necessary to provide a desirable 6 finish, such as a stippled stucco look, to the surface. Added effects, which may 7 be created on the surface of the joint compound, rely on the artistic ability and 8 the skill of the installer.
9 Construction systems are also known, using complete composite wall panels which comprise an inner layer of foam, such as a polystyrene foam, 11 covered with coatings, including cementitious materials. One such system is 12 taught in US patent 4,774,794 to Grieb wherein a fiberglass mat is positioned 13 over a foam core and the mat is subsequently coated with a cementitious 14 material containing fiberglass roving and a polymer adhesive acrylic material.
The mixture is laid over the fiberglass mat wherein it penetrates the mat and 16 adhesively bonds the coated mat to the foam core. Structures are constructed of 17 the blocks created using the method taught.
18 Others, such as US Patent 4,944,127 to Clear, utilize a plurality of 19 grooves on an outer surface of a foam layer to improve a mechanical lock between a cementitious layer applied to the foam layer and the foam layer itself.
21 There remains interest in the industry to provide an exterior panel 22 having an aesthetically pleasing surface that can be fastened to an exterior wall 23 of both new and existing structures and which is capable of imitating other 24 conventional exterior surface materials such as rock and brick or providing other architectural designs thereon. It is desired that coatings applied to the exterior 1 surface of such panels be strong, durable and relatively impenetrable yet 2 breathable to prevent moisture buildup between the panel and the exterior 3 surface of the structure. Further, the panel should be relatively inexpensive, 4 simple to manufacture and easy to install.
7 A unique exterior surface coating is provided for coating exterior 8 surfaces and for manufacturing and installing exterior wall panels which are 9 durable and are not readily penetrated. The coating comprises at least one acrylic resin; silica sand; and an effective amount of reinforcing fibers to provide 11 a surface coverage of fibers from about 5% to about 50% when applied to the 12 exterior surface.
13 In an embodiment of the invention, the resin comprises a mixture of 14 hard and soft acrylic resin to provide a resilient resin mixture which is combined with an effective amount of glass fibers to provide about 20% surface coverage 16 of fibers, The glass fibers are added to one part of resin and mixed therein after 17 which 2 to 3 parts by volume of a fine silica sand are added. The coating is 18 mixed after which it can be applied to the exterior surface using conventional 19 means such as a texture spray machine or by rolling.
In another embodiment, an exterior wall panel adapted for 21 application to a surface of a static structure is manufactured using the method 22 according to another embodiment of the invention. The panel comprises: a foam 23 sheet; the coating, as described, applied to an exterior surface of the foam 24 sheet; and means adapted for attaching the wall panel to the surface of the static structure. The panel can be fastened to the exterior surface using conventional 1 fasteners and adhesives or alternatively can be fastened using the coating as an 2 adhesive.
3 Preferably, a pattern, design or surface texture is imparted to the 4 foam sheet prior to the application of the coating. The markings are imparted using a variety of techniques including, but not limited to, the application of heat, 6 a heated template or solvent to the surface of the foam.
7 The panel may be manufactured having tongue and groove edges 8 which are engaged between adjacent panels for forming a substantially 9 continuous decorative surface. Alternately the panels may simply be butted against one another and the space between the adjacent panels filled with 11 caulking or with the coating.

5 2 Having reference to Figs. 1, 2, 3 and 7, exterior panels 1 of varying 3 shapes, sizes and surface finishing are shown according to embodiments of the 4 invention. In each embodiment the panel is manufactured using a foam sheet 2, such as Styrofoam to which a unique coating 3 is applied. Further, indicia or
6 designs 4 may be applied to an exterior surface 5 of the foam sheet 2 prior to
7 application of the coating 3 to achieve a plurality of decorative design finishes, as
8 may be desired.
9 An embodiment of the unique coating 3 comprises a 100% acrylic resin to which reinforcing fibers and silica sand are added. Reinforcing fibers, 11 such as those conventionally used in the concrete industry and typically ranging 12 from about 1/8" to about 5/8" long and even up to about 1'/2" long, are added to 13 the resin in an effective amount so as to provide a surface coverage of fibers, 14 when applied to the foam, in a range of from about 5% to about 50%. Most preferably, the fibers used are about'h" long and are added to provide a surface 16 coverage, when applied to the foam, of about 20%. The acrylic resin and fibers 17 are first mixed, such as in a hopper, after which silica sand is added to impart 18 additional strength, uniformity and to improve the aesthetics of the coating.
19 Sufficient silica sand is added in an amount sufficient to obtain a consistency which can be applied to the exterior surface 5 of the foam sheet 2 21 using conventional means, such as by roller or using a texture spray machine 22 such as is known in the industry. Additionally dyes or other coloring may be 23 added and mixed with the acrylic resin to improve the aesthetics of the finished 24 panel1.
1 In a preferred embodiment, the acrylic resin may comprise a 2 mixture of one or more acrylic resins, such as Resin #2000 and Resin #2438 3 available from Akrilon Industries Inc., Calgary, Alberta, Canada. Each of the 4 acrylic resins has a different hardness when applied and therefore when mixed together in varying amounts, the hardness and resilience of the coating can be 6 altered as desired. In one embodiment, the acrylic resin mixture comprises about 7 1/3 Resin #2000 (hard) and about 2/3 Resin #2438 (soft) to produce a resilient 8 coating which is durable and not readily penetrated.
9 Glass fibers, such as CONTROLT"" fibers available from Nycon, Inc., Rhode Island, USA, are added to the acrylic resin or acrylic resin mixture so 11 as to produce a surtace coverage of about 20% fibers. Approximately 3oz 12 (0.084kg) of fibers are added to each 5 gallon pail of acrylic resin and the fibers 13 and acrylic are then mixed to disperse the fibers therein.
14 Silica sand, in an amount ranging from about 2 to about 3 - 5 gallon pails is then added to the acrylic/fiber mixture and the resulting coating is mixed 16 until a uniform suspension is obtained. Preferably, fine silica sand such as 070 17 silica sand, available from Target Products Inc. of Burnaby, British Columbia, 18 Canada, is used.
19 Therefore, in one embodiment, the coating 3 comprises about 1 part by volume of acrylic resin combined with from about 2 to about 3 parts by 21 volume of silica sand and an effective amount of fibers to produce about 20%
22 surface coverage of fibers when applied to the foam sheet 2.
23 According to embodiments of the invention, a variety of exterior 24 surface panels 1 can be produced using the foam sheet 2 and embodiments of the coating 3, as described above. Further, the coating 3 may also be used to 1 coat existing surfaces such as drywall, wood, concrete and the like and can be 2 used as an adhesive for fastening panels 1 to exterior surfaces 6 of static 3 structures 7, regardless the surface material and as a caulking compound 4 between installed exterior surface panels 1, such as those described herein.
Preferably, desired patterns are applied to the foam sheet 2 prior to 6 applying the coating 3. Random patterning or patterns and designs using a 7 template can be imprinted on the exterior surface 5 of the foam 2 without a 8 requirement for specific artistic skills for economically producing large quantities 9 of a high quality product and the coating can be applied using conventional techniques such as spraying. Thus, reliance on artistic skills is reduced both in 11 the manufacture and in the application of an aesthetic surface to the exterior of a 12 building and the like.
13 Having particular reference to Figs. 1 and 2, in order to simulate 14 brick or stone or other architecturally-produced design, the exterior surface 5 of the foam sheet 2 may be initially imprinted with a pattern. One method of 16 imprinting the foam 2 as shown, is to apply a heated template 10, such as an 17 aluminum grid, to the exterior surface of the foam sheet 2 to brand the surface 5 18 of the foam 2 with the pattern by melting at least a portion of the foam's surface 19 5. For some designs, the branding creates depressions which simulate grout lines between brick or stones. In another embodiment, not shown, a narrow 21 heated roller is rolled along the surface of the foam to melt the depressions for 22 creating regularly spaced lines on strips of foam for simulating a block-like finish 23 or for other patterns as desired.
24 Patterns need not necessarily simulate only grout lines of regular or irregular stone and brick patterns. Other means may be used to texture the 1 exterior surface 5 of the foam 2, such as using solvents including lacquer 2 thinner. Such texturing may be used to simulate a hewn stone-like pattern on 3 the surface 5 of foam 2 for creating single block-like panels. Other architectural 4 patterns and pleasing finishes may be applied to the foam 2 using any means of marking the foam 2.
6 Once the exterior surface 5 of the foam 2 has been imprinted with 7 the pattern or marking, the coating 3 is applied to the foam 2.
8 Panels 1 may be created as single sheets of foam having an 9 overall pattern formed thereon or, as shown in Figs. 1 and 3 may be created using elongate strips 12 of foam 2 having a pattern formed on at least a portion 11 of each strip 12. The strips 12 can be fastened to the wall individually, using 12 fastening means 14 such as adhesives and fasteners, or can be held together as 13 a panel 1, such as by fabric strips 16 which are fastened to a top edge 17 of 14 each adjacent strip 12a, 12b and extending beyond for fastening to the wall or optionally to an overlapping strip. The overlapping strips 12a, 12b may optionally 16 be supported by vertical frame members 18 for installation on an exterior wall 17 surface.
18 The panels 1 are typically fastened to the exterior surface of a wall 19 using fastening means such as fasteners or adhesives. Where adjacent panels 1a, 1b are installed to create a substantially continuous decorative surface, joints 21 20 between the adjacent panels 1 a, 1 b may be tongue 21 and groove 22 joints 22 as seen in Fig. 4 In the case of tongue and groove joints 21, 22, opposing sides 23 of each panel 1 a may be formed having either a tongue 21 or a groove 22 which 24 is mated with a groove 22 or tongue 21 on the adjacent panel 1 b. Further, all 1 sides of a panel 1 may be formed having tongue or groove connections to permit 2 installing panels side by side and above and below one another.
3 Optionally, panels 1 a, 1 b may simply be positioned side by side 4 against one another, as seen in Fig. 5, any space 24 between the adjacent panels 1 a. 1 b, being sealed with caulking.
6 As shown in Fig. 6 and largely as a result of the resilient nature of 7 the reinforced acrylic coating 3, a portion 30 of the foam sheet 2 may be 8 removed from behind the coating 3, such as a V-notch, so as to permit the panel 9 1 to be folded and wrapped around a corner 31 in an exterior wall eliminating the need to use a separate corner bead. Alternatively (not shown), panels 1a, 1b 11 may be positioned to abut adjacent each side of the comer 31 and the opening 12 therebetween at the corner 31 may be caulked.
13 As shown in Figs. 5 and 7, edges of the panel 1 may be formed 14 having a bevel 32.
19 Sufficient silica sand is added in an amount sufficient to obtain a consistency which can be applied to the exterior surface 5 of the foam sheet 2 21 using conventional means, such as by roller or using a texture spray machine 22 such as is known in the industry. Additionally dyes or other coloring may be 23 added and mixed with the acrylic resin to improve the aesthetics of the finished 24 panel1.
1 In a preferred embodiment, the acrylic resin may comprise a 2 mixture of one or more acrylic resins, such as Resin #2000 and Resin #2438 3 available from Akrilon Industries Inc., Calgary, Alberta, Canada. Each of the 4 acrylic resins has a different hardness when applied and therefore when mixed together in varying amounts, the hardness and resilience of the coating can be 6 altered as desired. In one embodiment, the acrylic resin mixture comprises about 7 1/3 Resin #2000 (hard) and about 2/3 Resin #2438 (soft) to produce a resilient 8 coating which is durable and not readily penetrated.
9 Glass fibers, such as CONTROLT"" fibers available from Nycon, Inc., Rhode Island, USA, are added to the acrylic resin or acrylic resin mixture so 11 as to produce a surtace coverage of about 20% fibers. Approximately 3oz 12 (0.084kg) of fibers are added to each 5 gallon pail of acrylic resin and the fibers 13 and acrylic are then mixed to disperse the fibers therein.
14 Silica sand, in an amount ranging from about 2 to about 3 - 5 gallon pails is then added to the acrylic/fiber mixture and the resulting coating is mixed 16 until a uniform suspension is obtained. Preferably, fine silica sand such as 070 17 silica sand, available from Target Products Inc. of Burnaby, British Columbia, 18 Canada, is used.
19 Therefore, in one embodiment, the coating 3 comprises about 1 part by volume of acrylic resin combined with from about 2 to about 3 parts by 21 volume of silica sand and an effective amount of fibers to produce about 20%
22 surface coverage of fibers when applied to the foam sheet 2.
23 According to embodiments of the invention, a variety of exterior 24 surface panels 1 can be produced using the foam sheet 2 and embodiments of the coating 3, as described above. Further, the coating 3 may also be used to 1 coat existing surfaces such as drywall, wood, concrete and the like and can be 2 used as an adhesive for fastening panels 1 to exterior surfaces 6 of static 3 structures 7, regardless the surface material and as a caulking compound 4 between installed exterior surface panels 1, such as those described herein.
Preferably, desired patterns are applied to the foam sheet 2 prior to 6 applying the coating 3. Random patterning or patterns and designs using a 7 template can be imprinted on the exterior surface 5 of the foam 2 without a 8 requirement for specific artistic skills for economically producing large quantities 9 of a high quality product and the coating can be applied using conventional techniques such as spraying. Thus, reliance on artistic skills is reduced both in 11 the manufacture and in the application of an aesthetic surface to the exterior of a 12 building and the like.
13 Having particular reference to Figs. 1 and 2, in order to simulate 14 brick or stone or other architecturally-produced design, the exterior surface 5 of the foam sheet 2 may be initially imprinted with a pattern. One method of 16 imprinting the foam 2 as shown, is to apply a heated template 10, such as an 17 aluminum grid, to the exterior surface of the foam sheet 2 to brand the surface 5 18 of the foam 2 with the pattern by melting at least a portion of the foam's surface 19 5. For some designs, the branding creates depressions which simulate grout lines between brick or stones. In another embodiment, not shown, a narrow 21 heated roller is rolled along the surface of the foam to melt the depressions for 22 creating regularly spaced lines on strips of foam for simulating a block-like finish 23 or for other patterns as desired.
24 Patterns need not necessarily simulate only grout lines of regular or irregular stone and brick patterns. Other means may be used to texture the 1 exterior surface 5 of the foam 2, such as using solvents including lacquer 2 thinner. Such texturing may be used to simulate a hewn stone-like pattern on 3 the surface 5 of foam 2 for creating single block-like panels. Other architectural 4 patterns and pleasing finishes may be applied to the foam 2 using any means of marking the foam 2.
6 Once the exterior surface 5 of the foam 2 has been imprinted with 7 the pattern or marking, the coating 3 is applied to the foam 2.
8 Panels 1 may be created as single sheets of foam having an 9 overall pattern formed thereon or, as shown in Figs. 1 and 3 may be created using elongate strips 12 of foam 2 having a pattern formed on at least a portion 11 of each strip 12. The strips 12 can be fastened to the wall individually, using 12 fastening means 14 such as adhesives and fasteners, or can be held together as 13 a panel 1, such as by fabric strips 16 which are fastened to a top edge 17 of 14 each adjacent strip 12a, 12b and extending beyond for fastening to the wall or optionally to an overlapping strip. The overlapping strips 12a, 12b may optionally 16 be supported by vertical frame members 18 for installation on an exterior wall 17 surface.
18 The panels 1 are typically fastened to the exterior surface of a wall 19 using fastening means such as fasteners or adhesives. Where adjacent panels 1a, 1b are installed to create a substantially continuous decorative surface, joints 21 20 between the adjacent panels 1 a, 1 b may be tongue 21 and groove 22 joints 22 as seen in Fig. 4 In the case of tongue and groove joints 21, 22, opposing sides 23 of each panel 1 a may be formed having either a tongue 21 or a groove 22 which 24 is mated with a groove 22 or tongue 21 on the adjacent panel 1 b. Further, all 1 sides of a panel 1 may be formed having tongue or groove connections to permit 2 installing panels side by side and above and below one another.
3 Optionally, panels 1 a, 1 b may simply be positioned side by side 4 against one another, as seen in Fig. 5, any space 24 between the adjacent panels 1 a. 1 b, being sealed with caulking.
6 As shown in Fig. 6 and largely as a result of the resilient nature of 7 the reinforced acrylic coating 3, a portion 30 of the foam sheet 2 may be 8 removed from behind the coating 3, such as a V-notch, so as to permit the panel 9 1 to be folded and wrapped around a corner 31 in an exterior wall eliminating the need to use a separate corner bead. Alternatively (not shown), panels 1a, 1b 11 may be positioned to abut adjacent each side of the comer 31 and the opening 12 therebetween at the corner 31 may be caulked.
13 As shown in Figs. 5 and 7, edges of the panel 1 may be formed 14 having a bevel 32.
