INSULATIVE SIDING APPARATUS AND METHOD OF MAKING THE SAME
The present invention is (in some embodiments) a system of decorative siding panels made from high-density expanded polystyrene (EPS) foam, such panels configured for overlapping, having interlocking tongue and groove structure. These panels for covering a surface, such as wall sheathing, of a structure.
The present invention is a non-provisional of U.S. Application Ser. No. 60/746,910, filed on May 10, 2006, the disclosure of which is incorporated by reference.
FIELD OF THE INVENTIONThe present invention generally relates to coverings for structures such as homes, commercial or industrial buildings. One embodiment of the present invention particularly relates to foam insulative panels for such structures.
BACKGROUNDStucco has been used for many years as a veneer covering for both commercial and residential walls. There are three typical representative methods of stucco construction:
(1) The house is first covered with plywood, wafer board (OSB) or insulation board, then lathe is attached to the walls and sprayed with a cement coating to form a stucco wall. The surface would then be painted.
(2) The utilization of an Exterior Insulated Finishing System (“EIFS”). In one example implementation of EIFS, the relevant portions of the exterior of the house is covered with one-pound extruded polystyrene foam (“EPS”), one-inch thick. Lathe or fiberglass mesh is then attached to the EPS. A coating, called “brown coat,” is then troweled or sprayed onto the EPS as an under coat. After the brown coat dries, a finish coat of synthetic stucco is applied, usually with the coloring in it.
(3) Most recently, due to water intrusion problems which can result in mold issues, a combination of the two (stucco and EIFS) has been tried to reduce costs. Installation of this hybrid system usually begins with the exterior side of the sheathing covering the house being covered with a water resistant barrier of house wrap or weather resistant felt paper. The barrier covered house is then covered with a wall sheathing or surface (in example, plywood, OSB and EPS foam). Chicken wire or mesh (called lathe) then is installed over the substrate. A concrete layer is then either sprayed or troweled directly on the substrate/lathe. After drying, the concrete layer is painted with an acrylic top coat. This is commonly referred to as a “two-coat” or “three-coat” stucco system. The “three-coat stucco system” requires a “brown” coat, a second concrete coat, and then the finish coat (usually an elastomeric acrylic stucco or paint coating).
The problems with these prior systems include: (1) if the concrete coating ever fractures, which it inevitably does, water can run in behind the stucco and/or foam and cause problems (in example, mold, mildew, or wood rot) since the moisture cannot escape; (2) as the seasonal temperature changes, a large wall without expansion joints is continually stressed and develops waves, bulges, and eventually cracks; and (3) the onsite labor time window required is not especially friendly to stucco construction, for instance, bad weather can bring stucco work to a halt, low temperatures may result in the concrete not curing correctly (which itself results in later cracks and peeling), and freezing temperatures often negatively affect the curing of cement products.
The present invention is a system for covering the inside or outside surface of a structure, and the method of making said covering and its components.
While the present invention is susceptible of various modifications and alternative constructions, certain illustrated embodiments thereof have been shown in the drawings and will be described below in detail. It should be understood, however, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.
In the following description, the use of “or” indicates a non-exclusive, alternative without limitation unless otherwise noted. The use of “for example,” “in example,” “i.e.,” “e.g.,” “such as,” and the like indicates the disclosure of certain listed examples with the express intention that there are other objects of the same category that are not listed. The use of “including” means “including, but not limited to,” unless otherwise noted.
The figures show a number of embodiments of the present invention. One or more of these embodiments could be used in a wall panel system. One representative wall panel system would comprise the application of decorative siding panels (and associated structure) made from high-density expanded polystyrene (EPS) foam to the outside wall surface of a structure. These siding panels configured for overlapping, having an interlocking tongue and groove structure, for purposes of sealing out moisture.
Referring to
Because they are comprised of foam board, the panels can be cut into various decorative patterns, including but not limited to flat, grooved, lapboard, log shapes for log cabin look, etc. The panels could even be embossed by stamping, or various designs, such as brick patterns, rock or stone patterns, etc., could be applied or melted therein. The panels can also be colored and/or covered with various finishing treatments, as desired, to further add to their appearance. This variety of panel shapes and configurations (including how they are configured for attachment to one another) allows a designer and/or an installer great freedom in creating decorative patterns in the structure's covering.
In this description, the term “panels” refers to a sheet, regardless of length, width, thickness or shape, that forms a distinct (usually flat) section or component of a structure.
In the preferred embodiment, the main panels are 4′ by 8′ in size. One example of such a 4′×8′ panel can be seen in
The panels are configured to be interlocking and for being generally water/air tight. Being interlocking prevents water from traveling through the tongue and groove of the panels and/or from running horizontally (like lapboard siding typically does), thereby preventing water damage and/or mold.
Referring to
It is preferred that one or more of the top/bottom/first/second sides is configured to interlock with one or more adjacent panels/structures. The preferred manner of interlocking is through use of “tongue and groove” style interlocking. By such interlocking (overlapping/abutting), water and vapor flow is blocked and the resulting damage is prevented.
In such a tongue and groove arrangement, at least one of the sides has a tongue or other flange extending there-from. This tongue is for receipt into a groove on a second panel or building structural element. Note: while the phrase “tongue and groove” is used herein, such exact functionality is not required, for instance opposing flanges are intended within the definition of “tongue and groove.”
Referring particularly to
As is shown in
In the embodiment shown in
Such tongues and grooves can be formed in a number of ways, including but not limited to being cut or otherwise formed in the foam and being made from a separate material (metal, plastic, etc.) that is attached to the panel side (for example, by adhesives or fasteners).
Preferably, as is shown in
The term “surface 30” when used herein intended to represent not only the outside or exterior “surface” of the building structure, but also includes any and all construction materials that the panel and associated components can be attached to, such as a sheet of OSB, plywood, dry wall, etc., regardless of their location on the structure (exterior, interior, etc.).
It may be desirable to have tongues on at least one of the horizontal ends as well as on the vertical ends, and grooves on one of the horizontal ends and one of the perpendicular ends. Such an arrangement would allow adjacent panels to interlock together and would allow the panels to be installed either vertically or horizontally in a continual pattern to achieve a desired height or width.
However, do to the layout used in constructing the wall (for instance, it may be advantageous to start at the ends of the wall and work towards the center), situations may arise where adjacent panels are not configured for such “tongue and groove” interlocking, for instance, as shown in
It is preferred that, on the panels, the tongue be consistently on one side (left or right) and the top, with the groove on the other side and the bottom. If the side grooves are reversed, the panels must be left and right handed and cannot be rotated interchangeably. Further, panels can be made with the tongue on top and the groove on the other edges, with the utilization of an adapter that can be glued or otherwise fastened into a groove to provide a tongue as required.
Using such interlocking joints allows for expansion and contraction to take place, something that traditional foam/stucco methods, such as the EIFS, 2- and 3-part systems mentioned previously, are not particularly effective at doing. Because EIFS doesn't account for such expansion and/or contraction, oftentimes cracking in the finish results.
As discussed above, the panels can be fastened to the structure through use of at least one fastener (for example, a screw or staple), inserted through the tongue (as shown in
It is preferred that the vertical seams be sealed, while the horizontal seams are not. This allows the wall system to ventilate vapor and/or moisture out from the interior portions of the building structure while inhibiting exterior water penetration. Further, the backsides of the panels could be vertically or diagonally grooved to assist in the evacuation of moisture/condensation.
Referring now to
Preferably, a fastener 28 would be utilized to attach the starter section 42 to the structure 30. The starter section can be the first general structure attached (using fasteners) mounted to the wall surface, providing a flange (or groove) that the lowermost siding panel bottom edge mates with.
Referring now to
The flat end of this panel (510) connecting to the flat end of a second panel (510′) so as to make a corner. This corner being covered by a corner cover 76. Such a corner cover being a trim piece designed to be glued in place without use of fasteners after siding panels are secured to the structure. Corner trims allow the present invention to traverse around corners without showing fasteners on the outside thereof. A second type of corner trim would be an outside 45-degree corner—a shallow pop-out design designed to be used on 45-degree corners such as bay window or angled walls. Another type of corner trim would be on the inside corner which is shaped like a triangle shape designed to be used on an inside corner of a structure to hide the seam where the siding joins.
This panel 510′ connecting with a panel 10. These panels (10, 10′, 510, 510′) connecting to the sheathing 30, 30′ for covering the structure.

Another example (not particularly shown in
The panels may be coated with any number of coatings, including but not limited to hard finishes, rubbery “stucco-like” coatings, etc. Resins including hardeners and fireproofing can be applied to the outside. These coatings preferably being applied at the factory, rather than in at the job site, but could be applied at the job site. Noise reduction is another benefit of the present invention, a benefit that may be enhanced through use of coatings. Preferred coatings include but are not limited to a “stucco” finish, “sandstone” finish, and “smooth” finish.
“Stucco” finish. One example would be the application, to the panels and/or other components of the present invention, of a hard coating of an epoxy, polyurea or urethane (or any such coating mentioned herein). The coating could include a quantity of sand (or other granular/textured material) for texture/added strength and a paint coat to create a stucco-like appearance. This granular material can be added to the coating before or after it is applied to the components. Multiple plies of the coating and the material may be applied to increase the strength of the coating. Various grits of the material could be used to change the roughness of the finish.
“Sandstone” finish. One example would be the application, to the panels and/or other components of the present invention, of an epoxy, polyurea or urethane coating (or any such coating mentioned herein) with a quantity of sand (or other granular/textured material). A coating of paint (preferably acrylic) would then be applied, followed by a second (or more) coat of the granular/textured material. The granular/textured material preferably being applied and immediately shaken off so as to provide an attractive “sandstone” finish. A urethane sealer, preferably clear, can then be applied as a finish coat. The color of the paint (preferably acrylic paint) can reflect through the sand to change the apparent color of the sandstone finish.
“Smooth” finish. One example would be the application, to the panels and/or other components of the present invention, of a coating of urethane, polyurea, or the like (without sand), resulting in a smooth finish. Multiple coats can be applied for extra hardness and strength.

Optionally, as shown in the drawing, the sheathing wouldn't be a single piece but would be adhered directly to the panel 410′ (as described infra). In such an embodiment the fastener would pass through the sheathing and into a stud of the stud wall (or other structure), thereby attaching the panel to the structure. The sheathing, in this Figure, is shown configured for overlapping the joints of the connection, however such overlapping isn't mandatory and the sheathing could terminate that the end of rabbets.
As discussed above, the panels could be manufactured with the panels themselves backed, laminated, adhered or otherwise attached directly to the sheathing (the sheathing thus becoming, in this embodiment, a portion of the panel). Doing so would eliminate the need for the wall sheathing to be separately attached to the framed structure (for instance to the exterior portions of the stud wall).
This figure (
A foil coating and/or film could be applied to the back (house) side of the panels, this foil or other coating serving as additional R-value, as a moisture barrier, and/or providing a location for installation, instructions and other written materials to be printed.
Utilization of high-density expanded polystyrene (or equivalent foam) has an insulative benefit. Such panels provide an insulative R-value, typically an R-4.9 value for every inch of panel thickness. If the invented siding is used on the outside of a structure, the amount of insulation required within the building's wall can be reduced and/or eliminated, thereby saving construction costs and providing other benefits. For instance, if part of the R-value desired to be used in a wall, is applied to the outside of the building (as insulative siding), then the thickness of the walls themselves can be lower; from 2′ by 6′ construction, to 2′ by 4′ construction thereby saving the building and lumber costs.
In one example, two and one-quarter inch thick EPS foam is installed over a 2″×4″ framed stud wall having typical R-13 insulation. Such a combination would result in a wall with an overall thickness of approximately six (6) inches having a R-value of approximately R-24. Must most current walls (2″×6″ construction) have R-values around R-21. Thus, utilization of this embodiment in a 2″×4″ wall could achieve greater insulative value while reducing the costs of construction materials and labor over traditional 2″×6″ construction.
In another example, currently framed building structures have lower R-values at the location of studs and other structural members. Since the insulative siding's insulative value is applied over the entire exterior surface of the wall, as opposed to merely being insulated in-between the studs (as fiberglass insulation is, for example), the present invention provides superior insulation characteristics and a true R-value gain at all points in the wall.
Installation (in one embodiment) could start in the center of a stud wall with a panel having double tongue center pieces or using a female-to-female adapter (38) to convert a groove into a tongue. The installer would then work outwards both directions from there so that trimming would be equally on the wall's ends. Doing so would result in the most centered look upon the wall. Such a center piece thus designed as a starter panel for the center of a large wall. Thus allowing other siding panels to be installed on the sides creating even spacing at the end of the wall. Such a double tongue center piece could be used to utilize waste panel sections as well as on gables where a panel grooved on all sides is used. After cutting the panel diagonally, the tongue can be glued into the waste piece to locate the tongue where desired and make the panel usable.
Another manner of starting the wall would be to install a starter section (42) at the base of the wall. The installer could then begin at one side, preferably the left, and install the panels from left to right. The first panel is installed at the corner of the structure with the groove side of the panel adjacent to the corner. The groove side can be secured to the wall with the starter section or with screws or staples that will be hidden by the outside corner trim. For taller walls, the process would be repeated with the lower panel providing the tongue to interlock into the upper panels.
There are benefits to using some of the embodiments of the present invention. Some embodiments will be much quicker to install than traditional vinyl siding. Installation, in comparison to traditional stucco, has the potential of having about a thirty-percent (30%) lower installed cost than “EIFS” stucco applications and be competitively priced with “2 or 3 coat” stucco systems. Other benefits include the insulation R-value, expansion joints, reduced potential for cracks, flatness and consistency of the wall, and elimination of problems created from applying water based coatings under inclement weather conditions (i.e. freezing temperatures can inhibit or destroy the curing of cement or other water based products).
Since installation of the insulative siding is a siding process, it does not “shutdown” the construction of the building while it is being installed (a common problem with the installation of stucco). In addition, there is little mess and no overspray to get on windows or other parts of the structure that may be in a finished state. These benefits, again, are related to specific embodiments and may not be present in each embodiment.
There are many different types of siding panels that comprise the preferred embodiments of the present invention. This paragraph lists five examples of the many types. The first type being a siding panel that is 24″×48″ long having a tongue on top and one side, the groove on the bottom and the other side. A second being a 48″×48″ siding panel having a tongue on top and one side with a groove on the bottom and another side. Another siding panel could be the 24″×96″ panel having a tongue on top and on one side, the groove on the bottom and the other side. A fourth would be 48″×96″ in dimension having a tongue on top and one side, the groove on the bottom and the other side. Finally, a fifth would be a double tongue center panel having a tongue on top and on both sides with a groove on the bottom side. Other panel embodiments likewise exist.
