Description

TECHNICAL FIELD

The present invention relates generally to foam insulation boards, such as foam insulation boards for installation in a residential structure.

BACKGROUND

In constructing a building, and in particular a residential building like a house, a relatively thin panel board is commonly used to cover the structural framework of exterior walls. The board is typically fabricated from a low-cost, lightweight material having enhanced insulating properties, such as, for example, extruded or expanded polystyrene, polyisocyanurate, or polyurethane foam. Usually, the boards are sized for use in conjunction with conventional frame selections (that is, frames with wooden studs on 16 inch or 24 inch centers). The boards may also have varying thickness and compositions, depending on, among other considerations, the desired resistance to heat flow.

In some applications, an air and water or moisture barrier is provided between the interior and the exterior of the building. Generally, the barrier system is configured to “seal” the entire structure. This air and moisture barrier may be achieved using a layer of a plastic sheet known as a water resistive barrier in conjunction with the boards. In the alternative, the air and moisture barrier may also be achieved by affixing an adhesive carrier such as tape over the joints where the boards abut one another.

SUMMARY

Exemplary embodiments of foam insulation board and methods of installing the same are disclosed herein.

In one exemplary embodiment, a foam insulation board comprises a plurality of insulation panels hingeably connected by hinged portions. The foam insulation board has a folded configuration and an unfolded configuration. The hinged portions allow the insulation panels to fold flat against each other in the folded configuration. The plurality of insulation panels includes a first insulation panel and a plurality of additional insulation panels, one of which is an adjacent insulation panel adjacent to the first insulation panel. The first insulation panel also includes a starter portion that extends beyond at least the adjacent insulation panel of the additional panels.

DETAILED DESCRIPTION

FIGS. 1A, 1B, and 1C illustrate an exemplary embodiment of a foam insulation board 100. The foam insulation board 100 is a rectangular board that can be folded at substantially parallel hinged portions into a folded configuration (FIG. 1A) and an unfolded configuration (FIG. 1C). In the unfolded configuration, the insulation board 100 may be about 4 feet wide by 8 feet high or about 4 feet wide by 9 feet high. The width (W) and height (H) of the panel may be varied to suit different wall heights and widths. The foam insulation board 100 comprises three hingeably connected panels: a first panel 102, a second panel 104, and a third panel 106. While three panels are shown, additional panels may be included. For example, the board may have a similar overall width but be divided into more than three panels, each panel having a reduced width as compared to the first, second, and third panels 102, 104, 106. Alternatively, the overall width of the unfolded board may be increased by adding additional panels, for example, additional panels that are attached to board 100 adjacently to the third panel 106 or between the second and third panels 104, 106.

The thickness (T) of the board 100 can vary depending on the desired insulation properties. For example, the board may be about 0.5 inch thick, about 0.75 inch thick, or about 1 inch thick. In some exemplary embodiments, the foam insulation board 100 is a polystyrene foam board, such as an extruded polystyrene foam board or an expanded polystyrene foam board. The board 100 may also include an air barrier, an air and moisture barrier, and/or an air barrier and moisture retarder on one or both sides. Air and moisture barriers prevent air or moisture from passing through the panels, while a moisture retarder allows moisture to pass through the panel to prevent moisture build-up. These elements of an exemplary board may be selected by a building designer for various reasons, such as, for example, to improve the efficiency of a heating and air conditioning systems installed in the building.

The panels 102, 104, 106 are hingeably connected by first and second hinged portions 110, 112. The first and second panels 102, 104 are hingeably connected by the first hinged portion 110, and the second and third panels 104, 106 are hingeably connected by the second hinge portion 112. The board 100 is unfolded from the folded configuration in one motion during which the second and third panels 104, 106 are unfolded from the first panel 102 along the first hinged portion 110 while simultaneously being unfolded from each other along the second hinged portion 112 to be laid flat in the same plane as the first panel 102. FIGS. 1A, 1B, and 1C illustrate the unfolding of the insulation board 100 with an intermediate step shown in FIG. 1B to more clearly indicate how the board 100 may appear during the unfolding process.

In the folded configuration, the first panel 102 extends beyond the second and third panels 104, 106 to form an optional starter portion 120. The starter portion 120 is exposed when board is in the folded configuration to allow an installer to begin installation of the board without unfolding the board. In the folded configuration, the panels 102, 104, 106 lay flat in a stacked configuration, one on top of the other, as shown in FIG. 1A, to reduce the overall size of the foam board 100. The reduced size of the folded board 100 improves transportation to the job site and handling during installation as compared to a full size board that cannot be folded.

In the illustrated embodiment, the first panel 102 is wider than the second and third panels 104, 106 to provide for the starter portion 120 and the second and third panels 104, 106 are approximately equal in width. For example, in a board 100 that is 4 feet (48 inches) wide, the first panel 102 may be 18 inches wide while the second and third panels 104, 106 may be 15 inches wide, allowing for a 3 inch wide starter portion 120. In additional embodiments, however, the second and third panels 104, 106 may have different widths than one another, with the first panel 102 being wider than each of the second and third panels 104, 106 to provide for the starter portion 120.

The first and second hinged portions 110, 112 can be any kind of hinge that allows the panels 102, 104, 106 to lay flat in a stacked configuration, one on top of the other, as shown in FIG. 1A, when the board is in the folded configuration. For example, the panels may be separate parts that are joined with adhesive tape (not shown) or a hinge member (not shown). The hinge portions 110, 112 may also be formed by cutting nearly through one side of the foam insulation board 100, leaving a portion near the surface of the board 100 to operate as a hinge portion 110, 112. The hinge portions 110, 112 may also be bidirectional or unidirectional. That is, the hinge portions 110, 112 may allow the panels 102, 104, 106 to fold in both directions or only in one direction to lay flat upon one another in a stacked configuration. The hinge portions 110, 112 may act as an air barrier, sealing the panels 102, 104, 106 together.

In some embodiments, retaining portions (not shown) may be included on the surface of the panels 102, 104, 106 to prevent the panels 102, 104, 106 of the board 100 from unfolding until desired. The retaining portions are easily released, however, when the panels 102, 104, 106 are intentionally unfolded for installation of the board 100. In some embodiments, the retaining portions are released by applying force to unfold the panels 102, 104, 106. In some other embodiments, a releasing member (not shown) may be used to release the releasing portions and allow the board 100 to be unfolded. In these embodiments, the retaining portions may be located anywhere the panels 102, 104, 106 contact each other. The retaining portions can be any kind of retaining portion, such as, for example, non-permanent adhesive or other tacky substance, double-sided tape, hook and loop fastener, a mechanical latch, or the like.

In various embodiments, a retaining member (not shown) is secured to the exterior of the board 100 in the folded configuration. The retaining member is then untied, cut, or otherwise removed to allow the board 100 to be unfolded. The external retaining member may comprise one or more straps that wrap around the entire folded board 100, or may comprise one or more straps that connect any combination of the panels 102, 104, 106. In other various embodiments, the retaining members may be fasteners that penetrate the panels 102, 104, 106 to prevent the board 100 from unfolding. If a penetrating retaining member (not shown) is used, however, the resulting hole may require patching to maintain the insulation performance of the board 100.

FIGS. 2A and 2B show an end view of the insulation board 100 in the folded configuration. Each panel 102, 104, 106 has a first end 210 and a second end 212. When the board is unfolded into the unfolded configuration, the first end 210 of one panel interfaces with the second end 212 of an adjacent panel. As can be seen in FIG. 2A, the first and second ends 210, 212 of the panels 102, 104, 106 are flat and form a butt joint when the board 100 is unfolded. In other embodiments, as seen in FIG. 2B, the first end 210 comprises a tongue portion and the second end 212 comprises a groove portion, thereby forming a tongue and groove joint when the board 100 is unfolded. While the tongue and groove of the first end 210 and second end 212 in FIG. 2B are shown with a square shaped profile, any shape profile may be used, such as, for example, a triangular profile, a trapezoidal profile, a round profile, or the like. The ends 210, 212 do not have to be square and in some embodiments allow the board 100 to include a corner portion (not shown) when unfolded.

FIGS. 3A, 3B, and 3C illustrate the steps to affix an exemplary foam insulation board 100 to a framed wall 300 typical of a residential structure. The framed wall 300 is comprised of a plurality of framing members. In particular, vertical studs 302, 304, 306 are affixed to a bottom plate 310 and top plate 312. The studs are typically spaced approximately 16 inches apart on center. While a common wood frame wall is shown, the board 100 may be installed on any kind of interior or exterior wall of a structure if so desired by the builder or owner of the structure.

To install the foam insulation board 100, the installer holds the folded board 100 against the studs and secures the starter portion 120 of the first panel 102 to the wall using one or more fasteners (not shown). At this point, the board 100 is secured to the wall 300 and the installer can safely release the board 100 without risking damage or injury. In an embodiment of the board 100 including retention portions, such as adhesive portions, between the first, second, and third panels 102, 104, 106, safety of the installation procedure is further improved because the second and third panels 104, 106 are prevented from swinging out from the wall 300 after the starter portion 120 has been secured to the wall 300.

The installer continues installation by unfolding the board 100 until the second panel 104 and third panel 106 are flat against the wall 300. Additional fasteners are then used to secure the board 100 to the wall. The fasteners can be any kind of fasteners, such as, for example, nails, screws, adhesive, rivets, staples, or the like. The fasteners should be selected such that they securely affix the board 100 to the wall 300 without damaging the board 100. A combination of fasteners may also be used. For example, the board 100 may be glued to the wall 300 during installation and then further secured with nails.

FIGS. 4A, 4B, 4C, 4D, and 4E illustrate an exemplary embodiment of a foam insulation board 400. The foam insulation board 400 is a rectangular board that can be folded at substantially perpendicular hinged portions into a folded configuration (FIG. 4A) and an unfolded configuration (FIG. 4E). The foam insulation board 400 comprises four hingeably connected panels: a first panel 402, a second panel 404, a third panel 406, and a fourth panel 408. While four panels are shown, additional panels may be included. For example, the board may have a similar overall width but be divided into more than four panels, each panel having a reduced width or height as compared to the first, second, third, and fourth panels 402, 404, 406, 408. Alternatively, the overall width of the unfolded board may be increased by adding additional panels between, for example, the first and second panels 402, 404 and the third and fourth panels, 406, 408, or attached to the board 400 adjacently to second panel 404 and fourth panel 408.

The thickness of the foam insulation board 400 can vary depending on the desired insulation properties. For example, the board may be about 0.5 inch thick, about 0.75 inch thick, or about 1 inch thick. In some exemplary embodiments, the foam insulation board 400 is a polystyrene foam board, such as an extruded polystyrene foam board or an expanded polystyrene foam board. The board 400 may also include a moisture vapor barrier on one or both sides.

The panels 402, 404, 406, 408 are hingeably connected by first, second, and third hinged portions 410, 412, 414. The first panel 402 and second panel 404 are hingeably connected by the second hinged portion 412. The second panel 404 and the third panel 406 are connected by the first hinged portion 410. The third panel 406 and fourth panel 408 are connected by the third hinged portion 414. The second and third hinged portions 412, 414 are substantially aligned, while the first hinged portion 410 is substantially perpendicular to the second and third hinged portions 412, 414. The addition of a perpendicular hinged portion allows the insulation board 400 to be folded in two different directions, thereby further reducing the length and width of the folded configuration of the board 400 to allow for transportation in smaller vehicles or insertion through smaller openings in a building prior to installation.

In the folded configuration, the first panel 402 and fourth panel 408 extend beyond the second and third panels 404, 406 to form first and second starter portions 420, 422. Because the board 400 is folded in two directions, however, the starter portions 420, 422 may obstruct each other when the board 400 is fully folded. Thus, depending on the fastener used, an installer may need to partially unfold the board 400 to secure one of the starter portions 420, 422 to a wall. Alternatively, the first and fourth panels 402, 408 may fold in different directions along the second and third hinged portions 412, 412 so that the first starter portion 420 extends from a different side of the folded foam insulation board than the second starter portion 422.

The first and fourth panels 402, 408 are wider than the second and third panels 404, 406 to provide for the starter portions 420, 422. The first and fourth panels 402, 408 are approximately equal in width, and the second and third panels 404, 406 are approximately equal in width. For example, in an insulation board 400 that is 4 feet (48 inches) wide, the first and fourth panels 402, 408 may be 26 inches wide while the second and third panels 404, 406 may be 22 inches wide, allowing for a 4 inch wide starter portion 420.

The insulation board 400 is unfolded by first unfolding the first and second panels 402, 404 from the second and third panels 406, 408 along the first hinged portion 410 until the first panel 402 is aligned with the fourth panel 408 and the second panel 404 is aligned with the third panel 406. In this intermediate unfolded configuration the first and second starter portions 420, 422 are easily accessible by an installer. The second and third panels 404, 406 are then unfolded from the first and fourth panels 402, 408 along the second and third hinged portions 412, 414 until they lie flat and are aligned with the first and fourth panels 402, 408 in the unfolded configuration. Like the foam insulation board 100 discussed above, the foam insulation board 400 with four panels may also be secured in the folded configuration by retention portions (not shown) or retaining members (not shown).

The hinged portions 410, 412, 414 can be any kind of hinge that allows the panels 402, 404, 406, 408 to lay flat in the stacked configuration, one on top of the other, as illustrated in FIG. 4A when the board 400 is in the folded configuration. For example, the panels may be separate parts that are joined with adhesive tape (not shown) or a hinge member (not shown). The hinge portions 410, 412, 414 may also be formed by cutting nearly through one side of the foam insulation board 400, leaving a portion near the surface of the board 400 to operate as a hinge portion 410, 412, 414. The hinge portions 410, 412, 414 may also be bidirectional or unidirectional. That is, the hinge portions 410, 412, 414 may allow the panels 402, 404, 406, 408 to fold in both directions or only in one direction to lay flat upon one another in a stacked configuration.

The foam insulation board 400 is installed similar to the foam insulation board 100 shown in FIGS. 3A, 3B, and 3C. The starter portion 400 is first secured to a wall, and then the board 400 is unfolded and the remaining panels are secured to the wall. As with the foam insulation board 100, any kind of suitable fastener may be used to secure the insulation foam board 400 to a wall.
