INSULATING SIDING SYSTEM

BACKGROUND

The present disclosure relates to systems for providing insulation and siding panels on the exterior of a building, such as a house. Methods and processes for making and/or using such insulating siding systems are also disclosed.

In a building structure, such as a house, a frame is typically built. An exterior wall of plywood or material of similar function is then placed upon the frame to provide an exterior surface. A weatherproofing layer may cover the exterior wall. An insulation layer can then be placed, and finally a cladding, paneling, veneer, or siding is placed to provide the final exterior view.

Vinyl siding is a popular substitute for wood paneling and aluminum siding. It is easily cleaned, and it is resistant to deterioration. It may also be easily installed around windows and doors. Moreover, it may be produced in a variety of shapes and colors by known extrusion and molding processes at a relatively low cost per sheet or panel.

To enhance the thermal insulation of building structures, one or more layers of insulating material can be placed between the vinyl siding and the exterior wall of the building. For example, a layer of insulation can be placed on a exterior wall, and the vinyl siding then installed over the insulating layer. In other insulated siding systems, an insulated panel is generally attached to a veneer, such as a vinyl siding panel.

Current insulation and exterior finishing products are complex to install and have performance shortcomings. For example, rigid insulating sheathing and siding are installed in two separate steps and function separately from one another as well. The installation of insulation and siding is a two-step process that is complicated, time-consuming, and requires the installer to put excessive penetrations into the walls of a building, creating areas that are vulnerable to moisture intrusion. Because the fasteners used to attach siding panels to a wall restrict the movement of the panels, visual defects due to thermal expansion can occur as well. Also, when installing plank siding product, there is no natural alignment from course to course integrated into the siding product or the sheathing product. This forces the installer to strike chalk lines or use other secondary alignment devices, increasing the time and cost of the installation.

It would be desirable to produce additional insulated siding panel systems or assemblies that allow for simple production and easy installation.

DETAILED DESCRIPTION

A more complete understanding of the components, processes and apparatuses disclosed herein can be obtained by reference to the accompanying drawings. These figures are merely schematic representations based on convenience and the ease of demonstrating the present disclosure, and are, therefore, not intended to indicate relative size and dimensions of the devices or components thereof and/or to define or limit the scope of the exemplary embodiments.

Although specific terms are used in the following description for the sake of clarity, these terms are intended to refer only to the particular structure of the embodiments selected for illustration in the drawings, and are not intended to define or limit the scope of the disclosure. In the drawings and the following description below, it is to be understood that like numeric designations refer to components of like function.

The insulating siding systems of the present disclosure comprise a combination of a sheathing panel and a siding panel. Various embodiments of sheathing panels and siding panels will be described herein. Generally, any sheathing panel can be combined with any siding panel.

In some embodiments, referring to FIGS. 1-3, the insulating siding system 10 comprises a sheathing panel 20 and a siding panel 50. The sheathing panel 20 comprises a front surface 22 and a rear surface 24 which are spaced laterally apart from each other. The rear surface is generally planar or flat to conform to an exterior wall. The front surface 22 comprises a first slot 30 and a second slot 40. Each slot extends laterally into the sheathing panel and includes an upwardly facing channel 32, 42 spaced laterally from the front surface 22. Alternatively, each slot may be considered has having an upper surface 31, 41, and a lower surface 35, 45, the upwardly facing channel 32, 42 being located along the lower surface. The siding panel 50 comprises a front face 52, a first downwardly facing channel 60 that extends rearwards and has a rear wall 62, and a second downwardly facing channel 70 that extends rearwards and has a rear wall 72. The first slot 30 is sized to receive the rear wall 62 of the first downwardly facing channel 60 and the second slot 40 is sized to receive the rear wall 72 of the second downwardly facing channel 70. The front face 52 may generally be contoured to provide any desired profile.

In some embodiments, the first downwardly facing channel 60 extends rearwards from an upper edge 54 of the siding panel and the second downwardly facing channel 70 extends rearwards from a lower edge 56 of the siding panel.

Generally, the upwardly facing channel 32 of the first slot 30 has a height 34 that is equal to or greater than a height 64 of the first downwardly facing channel rear wall 62. Similarly, the upwardly facing channel 42 of the second slot 40 may have a height 44 that is equal to or greater than a height 74 of the second downwardly facing channel rear wall 72.

The siding panel 50 may further comprise a lower upwardly facing channel 80 between the lower edge 56 of the siding panel and the second downwardly facing channel 70.

If desired, an insulating panel 90 may be included with the insulating siding system. The insulating panel 90 can be located between the siding panel 50 and the sheathing panel 20 when they are assembled. In particular, the insulating panel 90 can have an upper edge 92 and a lower edge 94. At a minimum, the lower edge 94 of the insulating panel extends into the lower upwardly facing channel 80. The upper edge 92 of the insulating panel can also extend into the first or upper downwardly facing channel 60. Depending on the thickness of the insulating panel, the rear face 96 of the insulating panel 90 can abut or contact the front surface 22 of the sheathing panel 20.

The upper downwardly facing channel 60 should be sized so that it can contain the lip 36 of the first slot 30. If an insulating panel 90 is also used, then the first or upper downwardly facing channel 60 should be sized to contain the upper edge 92 of the insulating panel and the lip 36 of the first slot.

As seen in FIG. 4, as siding panels are integrated or connected to the sheathing panel 120, the second or lower downwardly facing channel 170 of a siding panel 110 will contain the first or upper downwardly facing channel 260 of the siding panel 210 below it. Put another way, the first or upper downwardly facing channel 260 of the siding panel is generally sized to fit within the second or lower downwardly facing channel 270.

However, this should not be construed as requiring the entire upper downwardly facing channel to fit within the lower downwardly facing channel. For example, the heights of the rear walls generally can vary. Thus, the height 74 of the lower downwardly facing channel rear wall 72 and the height 64 of the upper downwardly facing channel rear wall 62 can be the same or different. In addition, the thicknesses of the various walls of the channels may vary, as shown in later embodiments.

Again referring to FIG. 4, the two downwardly facing channels 260, 270 of the siding panel are not necessarily placed in two adjacent or consecutive slots. A third slot 150 may be located between the first slot 130 and the second slot 140.

Generally, the siding panel 210 is integrated with the sheathing panel 120 by inserting the rear wall 62 of the upper downwardly facing channel 60 into the first slot 30 and inserting the rear wall 72 of the lower downwardly facing channel 70 into the second slot 40. The siding panel 210 is then pushed downwards so that rear wall 62 enters upwardly facing channel 32 and rear wall 72 enters upwardly facing channel 42.

The first slot and the second slot need not have the same dimensions. As mentioned above, all that is required is that the first slot be sized to receive the rear wall of the upper downwardly facing channel and the second slot be sized to receive the rear wall of the lower downwardly facing channel. This feature may be helpful, for example, in specifying locations on the sheathing panel in which the siding panel(s) can and cannot be placed. However, in specific embodiments, the first slot and the second slot have the same dimensions to promote interchangeability and allow the installer to fit the panels as needed. In addition, the spacing between adjacent slots and the size of the channels, both in height and width, can vary in the various embodiments of the sheathing panel.

Referring to FIGS. 5-7, the insulating siding system 310 may be considered as comprising a sheathing panel 320 and a siding panel 350. The sheathing panel 320 comprises a rear surface 324 and a forward surface 326. The forward surface 326 comprises a first row 330 and a second row 340. The two rows extend laterally from the forward surface 326 to define a front surface 322. The second row 340 has a ridge 342 extending upwardly at the front surface 322 between the first row 330 and the second row 340 to define a slot 345. The siding panel 350 comprises a front face 352 having an upper edge 354 and a lower edge 356. A lower downwardly facing channel 370 extends rearwards from the lower edge 356 and has a rear wall 372. The slot 345 on the sheathing panel is sized to receive the rear wall 372 of the lower downwardly facing channel. The ridge 342 may have a height 344 that is equal to or greater than a height 374 of the lower downwardly facing channel rear wall 372.

The siding panel 350 may further comprise an upper downwardly facing channel 360 that extends rearwards from the upper edge 354 and has a rear wall 362 as well. Again, an insulating panel 390 could be placed between the siding panel 350 and the sheathing panel 320. Again, the downwardly facing channels of the siding panel do not need to be placed in adjacent or consecutive slots on the sheathing panel. The sheathing panel 320 can further comprise a third row 380 that extends laterally from the forward surface 326 so that the first row 330 is between the third row 380 and the second row 340. The third row 380 has a ridge 382 extending upwardly at the front surface away from the first row 330 to define a third row slot 385, and the third row slot 385 is sized to receive the rear wall 362 of the upper downwardly facing channel 360.

Each ridge 342 can extend from about one-third to about two-thirds of the distance between two adjacent rows. Put in different terms, the ridge 342 has a height 344, and the slot 345 has a height 347, wherein the ratio of the slot height 347 to the ridge height 344 is from about 1:2 to about 2:1.

Referring to the embodiments shown in FIGS. 8-10, the sheathing panel 420 comprises a front surface 422 and a rear surface 424 which are spaced laterally apart from each other. The front surface 422 comprises a first slot 430 and a second slot 460. Each slot 430, 460 comprises an upper surface 432, 462 extending laterally into the front surface 422, a rear surface 434, 464 extending downwards from the upper surface and having a rear surface height 436, 466, a lower surface 438, 468 extending from the rear surface laterally towards the front surface 422 for a lower surface width 440, 470, a forward surface 442, 472 extending upwards from the lower surface for a forward surface height 444, 474, a medial surface 446, 476 extending from the forward surface to the front surface for a medial surface width 448, 478, and a slot entry height 450, 480 between the upper surface 432, 462 and the medial surface 446, 476. The siding panel 500 comprises a front face 502 and a rear face 504, an upper channel wall 510 extending rearwards from the rear face and having an upper channel wall width 512, an upper channel rear wall 514 extending downwards from the upper channel wall and having an upper rear wall height 516, a bottom wall 520 extending rearwards from the rear face, a lower channel front wall 522 extending upwards from the bottom wall, a lower channel top wall 524 extending rearwards from the lower channel front wall and having a lower top wall width 526, and a lower channel rear wall 528 extending downwards from the lower channel top wall and having a lower rear wall height 530. The slot entry height 450 of the first slot 430 is equal to or greater than the upper rear wall height 516 and the slot entry height 480 of the second slot 460 is equal to or greater than the lower rear wall height 530.

In some embodiments, the upper channel wall 510 extends rearwards at an upper edge 506 of the siding panel, and the bottom wall 520 extends rearwards at a lower edge 508 of the siding panel.

The first slot forward surface height 444 can be equal to or greater than the upper rear wall height 516. Similarly, the second slot forward surface height 474 can be equal to or greater than the lower rear wall height 530.

When an insulating panel 550 is used, the lower edge 552 of the insulating panel can extend into a channel formed by the lower channel front wall 522, the bottom wall 520, and the front face 502. If desired, the upper edge 554 of the insulating panel can extend past an edge 518 of the upper channel rear wall 514. The upper channel wall width 512 should be equal to or greater than the sum of the insulating panel upper edge width 556 and the medial surface width 448.

Again, when the siding panels overlap, it is clear that the lower top wall width 526 is equal to or greater than the upper channel wall width 512. The upper rear wall height 516 and the lower rear wall height 530 can be different or the same (i.e. equal or unequal to each other). Again, the first slot 430 and second slot 460 can have the same dimensions or different dimensions. A third slot 570 can also be located between the first slot 430 and the second slot 460.

The ratio of the slot entry height 450, 480 to the forward surface height 444, 474 for each slot can be independently from about 1:2 to about 2:1. Alternatively, the forward surface height 444, 474 can be about one-third to about two-thirds of the rear surface height 436, 466.

Referring to embodiments shown in FIGS. 11-13, the sheathing panel 620 comprises a front surface 622 and a rear surface 624. The front surface 622 comprises a first slot 630 and a second slot 640. Each slot 630, 640 extends rearwards into the sheathing panel and includes an upwardly facing channel 650, 660 spaced apart from the front surface. The siding panel 670 comprises a front face 672, a rear face 674, an upper connecting wall 680 extending rearwards from an upper portion 676 of the rear face, an upper rear wall 682 extending downwards from the upper connecting wall, and a lower rear wall 692 connected to a lower portion 678 of the rear face by a lower connecting wall 690 and extending downwards from the lower connecting wall. The first slot 630 is sized to receive the upper rear wall 682 and the second slot 640 is sized to receive the lower rear wall 692. The upper connecting wall 680 can extend rearward from the upper edge 673 of the siding panel and the lower connecting wall 690 can extend rearward from the lower edge 675 of the siding panel if desired.

The height 652 of the upwardly facing channel 650 of the first slot 630 is equal to or greater than the height 684 of the upper rear wall 682. Similarly, the height 662 of the upwardly facing channel 680 of the second slot 640 is equal to or greater than the height 694 of the lower rear wall 692.

The lower connecting wall 690 can be shaped to provide a lower upwardly facing channel 695 between the front face 672 and the lower rear wall 692. An insulating panel 700 can be inserted there. A portion 697 of the lower connecting wall 690 adjacent to the lower rear wall 692 can also have a width 696 that is equal to or greater than a width 686 of the upper connecting wall 680. The upper connecting wall has a width 686 that is greater than the sum of the upper edge width 702 of the insulating panel and the lip width 634 of the first slot 630.

Referring to embodiments shown in FIGS. 11, 13, and 14, the sheathing panel 620 comprises a front surface 622 and a rear surface 624. The front surface 622 comprises a first slot 630 and a second slot 640.

The rear wall 1362 may comprise an upper portion 1364 extending transversely above the connecting wall 1360 and a lower portion 1366 extending transversely below the connecting wall.

The siding panel 1330 may also comprise an upper connecting wall 1370 extending from the rear face 1354, an upper rear wall 1372 extending downwards from the upper connecting wall, an lower connecting wall 1380 extending from the rear face, and a lower rear wall 1382 extending upwards from the lower connecting wall. As seen in FIG. 21, the upper connecting wall 1370, upper rear wall 1372, lower connecting wall 1380, and lower rear wall 1382 can be used to further secure the siding panel by fitting into parts of two other slots 1390, 1395. Put another way, these additional connecting walls and rear walls are sized to collectively fill the cavity of one slot.

Referring to FIGS. 22 and 23, the siding panel 1450 may alternatively be described as comprising a front face 1452 and a rear face 1454. The rear face comprises at least one receptacle 1460, including at least two receptacles. The receptacle has a receptacle entry height 1465 and extends into the siding panel to form a cavity 1470. The cavity has a cavity height 1475 which is greater than the receptacle entry height 1465. Though not shown here, if desired, a veneer panel, similar to that shown in FIG. 15, may be attached to the front face 1452. The sheathing panel 1420 may alternatively be described as comprising a front face 1422 and a rear face 1424. A connecting wall 1430 extends from the front face to a front wall 1432 extending transversely from the connecting wall. The height 1435 of the front wall 1432 is greater than the receptacle entry height 1465. The cavity 1470 may also be described as including a downwardly extending channel 1472 located along an upper surface 1462 of the receptacle 1460 and an upwardly extending channel 1474 located along a lower surface 1464 of the receptacle.

The front wall 1432 of the sheathing panel is sized to substantially fill the cavity 1470. In other embodiments, the connecting wall 1430 and the front wall 1432 of the sheathing panel are sized to substantially fill the receptacle 1460. The front wall 1432 may extend substantially perpendicularly from the connecting wall. The front wall 1432 may also comprise an upper portion 1434 extending transversely above the connecting wall 1430 and a lower portion 1436 extending transversely below the connecting wall.

The siding panel 1450 also has an upper edge 1456 and a lower edge 1458. In some embodiments, the lower edge 1458 includes a recess 1480 having a width 1482 that is equal to or greater than the width 1457 of the upper edge 1456.

In these insulated siding systems shown in FIGS. 19-23, the siding panel is integrated with the sheathing panel by sliding the siding panel from the side into the sheathing panel. Unlike the siding panels shown in FIGS. 1-18, these siding panels cannot be inserted into the sheathing panel from the front. However, if desired, the siding panels of FIGS. 1-18 could be used with the sheathing panel of FIGS. 19 and 22.

FIGS. 24-26 show yet another exemplary embodiment of an insulated siding system 1510. Again, the sheathing panel 1520 has a front face 1522 and a rear face 1524. Here, rather than continuous slots running the length of the sheathing panel along the front face, the front face 1522 comprises a plurality of sockets 1530. The siding panel 1550 comprises a front face 1552 and a rear face 1552. Instead of channels, a plurality of plugs 1560 extend from the rear face. At least two plugs are generally required to prevent the siding panel from rotating; here, the siding panel is depicted as having six plugs. Again, the lower edge 1556 of the siding panel 1550 may include a recess 1570 having a width 1572 that is equal to or greater than the width 1555 of the upper edge 1554 of the siding panel. The siding panel is attached to the sheathing panel by pushing the plugs 1560 of the siding panel into the sockets 1530 on the front of the sheathing panel. Of course, not all sockets must receive a plug. As depicted in FIG. 24, the sheathing panel 1520 and siding panel 1550 are joined together by a ball-and-socket arrangement. Of course, the roles may be reversed if desired, so that the rear face of the siding panel comprises a plurality of sockets and the front face of the sheathing panel comprises a plurality of plugs. The plug can be shaped, if desired, with a tapered surface that makes inserting the plug into the socket easy, but removing the plug difficult, such as with a snap-fit mechanism.

Interestingly, in this embodiment, the cross-section of the sheathing panel 1520 shown in FIG. 25 is very similar to the sheathing panel 1320 of FIG. 19 and the cross-section of the siding panel 1550 shown in FIG. 26 is very similar to the siding panel 1350 of FIG. 20. For example, the socket 1530 could be considered a cavity 1340 and the plug 1560 could be considered a combination of the connecting wall 1360 and rear wall 1362. However, unlike the combination of FIGS. 19 and 20, the siding panel of FIG. 25 must be inserted from the front, not the side.

If desired, the insulating panel (reference numeral 90 in FIG. 2) can be attached to the siding panel (reference numeral 50 in FIG. 2) in a variety of ways including, but not limited to, adhesive, chemical bonding, interlocking complementary surfaces, and/or fasteners. Typically, however, adhesives are used. The adhesive may be used over the entire surface of the siding panel or in discrete locations instead. Suitable adhesives may include, but are not limited to, UV curable adhesives and hot melt adhesives, such as polyamines and urethanes, glue, thermosetting or thermoplastic adhesives, pressure sensitive adhesives or solvent-based adhesives.

The sheathing panel and/or the insulating panel, when present, may be shape molded. Such molding operations will generally impart the desired contours and/or design to the sheathing panel. Typically, pellets of a polymeric precursor material are placed in a suitably configured die mold, then reacted in the presence of water and heat to expand during the reaction process. The polymeric precursor material expands and presses against the die surface to form compressed elongated closed cells that form a characteristic tough smooth skin. The shape molded process produces a panel that is essentially straight, free of camber, and/or self-supporting. The various grooves, slots, and channels of the sheathing panel may be obtained by any combination of computer numerical control (CNC) cutting, milling, wire-cutting, or during the shape molding process as well.

The sheathing panel and/or insulating panel is generally made from a cellular foam product, i.e. a plastic or polymeric material with numerous cells of trapped air distributed throughout its mass. For example, expanded polystyrene (EPS) is a cellular foam plastic made from beads of polystyrene beads that are first pre-expanded and allowed to rest for a suitable interval, then molded in closed steam-heated shaped molds to produce closed-cell molded foams. The size and density of the closed cells can be controlled and may vary depending upon the application. Suitable materials for the sheathing panel can include expandable polystyrene (XPS), expanded polystyrene (EPS), polyurethane, polyisocyanurate, polyethylene, polypropylene, or combinations thereof.

The sheathing panel and/or insulating panel can be of any density desired, or be tuned to provide different densities depending on the location. For example, it may be desirable to have higher densities where the sheathing panel is thin, and lower densities where the panel is thicker. Similarly, it may be desirable to have higher densities near the edges of the insulating panel, and lower densities near the center of the insulating panel (where it is covered by the siding panel).

Expanded or expandable polystyrene are particularly desirable materials for the sheathing panel and/or insulating panel because they provide a solid feel; improve the R-value; deaden noise transmitted through the siding; and channel heat and water away into the external environment, protecting the exterior wall behind the sheathing panel and reducing mold growth.

The various slots, grooves, and channels could also be made out of different materials, such as plastics or metals, instead of being milled or wire-cut from a foamed sheet. For example, the rows, ridges, and lips could be inserted into a flat foamed sheet and fastened with adhesive, tape, screws, or other mechanical fasteners. Alternatively, the rows, ridges, and lips may be inserted into the foamed sheet and fastened mechanically during the shape molding process. The plastic or metal piece could be inserted and the foam would be expanded and fused around it. No secondary fasteners or additional fastening step would be required. FIG. 27 illustrates this method of making the slots in the sheathing panel. Here, a foam sheet 1600 is partially foamed to include holes 1610 into which plastic or metal pieces 1620 are inserted. The foam sheet is then expanded around the piece 1620 to form the final sheathing panel 1630 and fix the piece 1620 in place. For example, the piece 1620 has a lip 1625 which is filled with foam in the sheathing panel 1630.

The siding panel can generally be formed from any suitable polymeric, metallic, cementious or composite material. Exemplary materials include vinyl, polypropylene, fiber-cement material, polyolefins, polyvinyls, polycarbonates, polyacetals, polysulfones, polyesters, polyamides, multilayer films, polyethylene (HDPE), polypropylene, low density polyethylene (LDPE), CPVC ABS, ethyl-vinyl acetate, various extruded ionomeric films, polyethylene based films, or combinations thereof. Other siding materials suitable for the siding layer include wood, aluminum, and steel.

Generally, siding must be thick to resist sagging and retain the desired shape. However, the insulating panel allows the siding panel to be thinner than otherwise necessary. The siding panel only has to provide weatherability to the siding panel assembly. Whereas traditional vinyl veneer sidings have a minimum material thickness of 0.040 inches, the siding panels of the present disclosure may have a thickness from 0.020 to 0.036 inches.

The downwardly facing channels or connectors can be made integral with the front face of the siding panel, or as separate pieces attached to the front face.

In embodiments such as that shown in FIG. 15, the siding panel is generally made from a cellular foam product, as described above with respect to the insulating panel. The veneer panel can be made from suitable materials as described with respect to the siding panel.

The sheathing panel can have a length of between 12 and 240 inches and will typically have lengths of 48 to 96 inches, as desired or required. The sheathing panel's height may be between 12 and 240 inches, and the sheathing panel may have a width (from rear surface to front surface) of 0.1875 to 36 inches. The siding panel or veneer panel can have a total thickness of from about 0.2 to about 4 inches.

The sheathing panels and siding panels are used in suitable combinations as insulating siding systems of the present disclosure to be affixed to or attached to exterior walls of a building. The foam sheathing with integral receivers/connectors allow easy, straight alignment and fastening of the siding panels without the use of fasteners that must go through the siding panel. The combination of the slots/channels of the sheathing panel with the siding panels above and below generally restrict the movement of a siding panel in any direction. Installation and alignment of the siding panels is made easier. Because the siding panels present a solid, unpenetrated façade, there are fewer places through which moisture can penetrate into the exterior wall. Defects related to the expansion of the siding panels is also minimized.

While particular embodiments have been described, alternatives, modifications, variations, improvements, and substantial equivalents that are or may be presently unforeseen may arise to applicants or others skilled in the art. Accordingly, the appended claims as filed and as they may be amended are intended to embrace all such alternatives, modifications variations, improvements, and substantial equivalents.
