1. Technical Field
The present invention relates to an insulating system for use in buildings. More particularly, the present invention relates to a supplemental insulating cover for insulating attic openings. Specifically, the present invention relates to an insulating cover configured to fit over and receive therein a rigid insulating and sealing member atop an attic opening.
2. Background Information
Houses are commonly provided with a pull-down foldable ladder providing access to an attic. The attic opening is provided with a spring-loaded door which is pivotally mounted at one end. The foldable ladder is mounted to the top side of the door and such offers support to the ladder when it is unfolded, the foot of the ladder resting on the floor of a hallway or a room. The door is provided with a rope on the bottom side to pull the door downwardly so that the ladder can be unfolded to provide access to the attic.
The closure is generally located between two joists so that when the ladder is in a folded mode, it is located between the joists. Although insulation is commonly provided between the joists in the attic, for obvious reasons it is believed, the area surrounding and over the ladder is not. Moreover, it will be appreciated that the attic closure does not, in and of itself, provide a good seal with the opening in the attic floor. Thus, there is a crack or void through which hot air can be lost from the house in the winter and cold air in the summer, if the house is air conditioned. The heat loss through the stairwell, even though the area not provided with insulation is small, is considerable particularly in the colder climates. This, of course, results in greater heating bills. In a similar manner, an air-conditioned or cooled home in a warmer climate can allow hot air to flow into the living space, particularly, leading to greater costs to cool the living space within the home.
To combat these problems, devices are known to exist that cover attic openings, and many devices are known to cover attic openings having staircases in the folded position. Exemplary proposed solutions of others to combat these problems are shown in U.S. Pat. Nos. 5,628,151; 4,281,743, 4,658,555, 5,475,955, 4,151,894, 4,832,153; as well as in U.S. Pat. App. Publ. Nos.: 2004/0055819; 2013/0219804; and in a device commercially available for sale, known as a Therma-Dome® by Yankee Insulation Products, LLC of New Boston, N.H.
Although these devices are somewhat satisfactory in insulating attic openings, in real world applications issues continue to exist with their insulation properties inasmuch as they still lack the insulation rating (R-value) equivalent of the surrounding attic floor space. One way of combatting these problems associated with the relatively low R-value of the above mentioned devices is draping loose insulation over or affixing it to such insulating cover units. However, this option does not ensure that the insulation remains in place when the cover is moved, and it does not guarantee a completely effective insulative barrier, since any voids in the insulation will diminish the desired effect of any additional insulation placed thereon. The present invention addresses these and other issues.
In one aspect, the invention may provide a manner in which an individual that is concerned about maintaining a consistent insulation rating between attic floor space and the area over attic openings may do so by neatly and evenly applying additional insulation to an existing attic opening insulating cover. One embodiment of the invention may provide a preformed containment area, which allows the individual to install one of a number of types of insulation (including, but not limited to fiberglass batt or blown-in cellulose insulation), to an even and consistent depth on all sides of the existing attic opening insulating cover.
In another aspect, an embodiment of the present invention is configured to meet the need for supplemental insulation as required by building code requirements or individual preference when a standalone device, such as an insulated attic cover lacks the required R-value. An embodiment of the invention may provide a supplemental cover having preformed panels to fit snugly over an existing insulated attic opening cover, and will form a container that allows an even distribution of an insulating material on the top and each of the four outer sides (or any combination thereof) of the existing attic insulating and sealing member.
In another aspect, the invention may provide an insulating supplemental cover to insulate an area above an attic opening, the supplemental cover comprising: a plurality of connected walls creating a box-like structure; an interior chamber defined by the inner surfaces of connected walls, said interior chamber adapted to house insulation therein; and a cavity defined by the outer surfaces of connected walls, the cavity adapted to receive a rigid attic insulating and sealing member at least partially therein.
In another aspect, an embodiment of the invention may provide an insulating system for placing within an attic above an opening, the system comprising: a rigid attic insulating and sealing member; and a supplemental cover defining a chamber therein for filling with insulation, and a cavity formed by the outer surface of the cover, wherein the sealing member is received at least partially in the cavity.
A sample embodiment of the invention, illustrative of the best mode in which Applicant contemplates applying the principles, is set forth in the following description, is shown in the drawings and is particularly and distinctly pointed out and set forth in the appended claims.
Similar numbers refer to similar parts throughout the drawings.
As shown throughout the Figures, an insulation system 1 comprises a supplemental insulating cover shown as 10 in
With primary reference to
Endwalls 22, 24 intersect sidewalls 18, 20 in a generally perpendicular manner to define a generally box-like structure. Top panel 16 and bottom panel 26 connect to sidewalls 18, 20 and endwalls 22, 24 to respectively define the top and bottom of the box-like structure. Cover 10 defines a fillable and hollow chamber 44 therein. While it is preferable in this embodiment that sidewalls 18, 20 are generally parallel, there may be instances where sidewalls 18, 20 are not parallel. For example, some generally rigid members 12 known to exist in the art are not rectangular in shape, they are trapezoidal. If generally rigid member 12 is trapezoidal, then clearly sidewalls 18, 20 will not be parallel either to allow cover 10 to properly fit over member 12.
Cover 10 is preferably a substantially non-rigid and at least semi-flexible structure, yet there may be some semi-rigid components as described below. In one particular embodiment, top and bottom panels 16, 26, sidewalls 18, 20 and endwalls 22, 24 are constructed of a polymer based flexible material such as an LDPE (polyethylene film). Alternatively, a fabric or non-woven fabric (NWF) could be used to construct the top and bottom panels 16, 26, sidewalls 18, 20 and endwalls 22, 24 that define cover 10. Further, while it is preferable that top and bottom panels 16, 26, sidewalls 18, 20 and endwalls 22, 24 are flexible, it is clearly possible that top and bottom panels 16, 26, sidewalls 18, 20 and endwalls 22, 24 may be semi-flexible or generally rigid to define chamber 44. The material thickness of top and bottom panels 16, 26, sidewalls 18, 20 and endwalls 22, 24 of cover 10 is sufficient to hold insulation 46 in chamber 44 without adding unnecessary weight of system 1 by creating an unnecessarily thick cover 10. Seams (unnumbered) extending along the intersection of respective panels and walls of cover 10 are formed using a heat-seaming device (not shown) to seal overlapping segments of adjoining panels, however it is clearly contemplated that other manners of forming seams are entirely possible as one having skill in the art would understand. If cover 10 is a NWF, the seams could need to be stitched or heat-seamed or formed in another manner as one having skill in the art would understand.
In one exemplary embodiment for covering an attic staircase opening, supplemental cover 10 has the following non-limiting dimensions when filled with insulation 46: a longitudinal length measured endwall 22 to endwall 24 from about 70 to about 85 inches; a lateral width measure sidewall 18 to sidewall 20 from about 40 to about 50 inches; and a vertical height measured top panel 16 to bottom panel 26 from about 15 to about 25 inches.
As shown in
With primary reference to
Chamber 44 may be filled with blown insulation 46 by inserting hose 48 through slit 42. Alternatively, a non-blowable insulation 46, such as fiberglass insulation as understood in the art, may be inserted through slit 42 into chamber 44 by hand. Chamber 44 may have a depth configured to fit full sized R-30 fiberglass insulation. By way of non-limiting example, interior chamber 44 has a depth of about nine inches measured from top panel 16 to bottom panel 26. The nine inch depth is configured to accommodate R-30 fiberglass insulation, however the depth could vary to accommodate alternatively R-valued fiberglass insulations which would have associated thicknesses.
Insulation 46 is a conventionally acceptable form of attic insulation. Some non-limiting examples of insulation that may be used are fiberglass, mineral wool, plastic fiber, natural fiber, conventionally known batting, foam or foam board, cellulose, conventionally understood expanding insulation, or any variety of combinations thereof. Alternatively, if a non-blown insulation is used, such as a blanket or roll type, insulation 46 may be inserted into chamber 46 through slit 42 by hand. A non-limiting example of insulation 46 that may be used in system 1 is a R-30 fiberglass unfaced continuous roll, commercially known as EcoTouch™ available for sale by Owens Coming Corporation of Toledo, Ohio.
In exemplary embodiments, about twenty pounds of insulation 46 is used to fill chamber 44 by inserting the insulation 46 through slit 42. When using roll insulation 16 as described above, it is contemplated that the roll will be cut into various segments so the cut insulation segments can be laid within chamber 44. For example, a first set of two cut segments of roll insulation 46 have a width of about 15 inches and a length of about 62 inches and a thickness of about 9 inches. One of these two segments from the first set is disposed between a sidewall 18 and inner wall 32 within the chamber 44. The second of these two segments from the first set is disposed between sidewall 20 and inner sidewall 30 within the chamber 44. A second set of two cut insulation segments of roll insulation 46 have a width of about 15 inches and a length of about 46 inches and a thickness of about 9 inches. One of these two segments from the second set is disposed laterally between endwall 22 and inner endwall 36 within chamber 44. The second of these two segments from the second set is disposed between endwall 24 and inner endwall 34 within chamber 44. A third set of three cut insulation segments of roll insulation 46 have a width of about 15 inches and a length of about 78 inches and a thickness of about 9 inches. Each of the cut segments are disposed longitudinally side-to-side and positioned below top panel 16 and above the first set, the second set, and the upper inner panel 28 within chamber 44. When arranged in the above described manner, flexible cover 10 retains the shape of the laid insulation 46 segments and retains the shape of insulating and sealing member 12 when covering the insulating and sealing member 12.
As depicted in
With continued reference to
As shown throughout the Figures, supplemental cover 10 receives generally rigid insulating and sealing member 12 at least partially in cavity 40. Rigid member 12 is also a box like structure configured to engage the attic floor 60 above attic opening 14. Rigid member 12 includes a generally rigid top panel 12a, sidewalls 12b, 12c, and endwalls 12d, 12e, and a bottom wall 12f. The rigid member walls define a rigid member cavity 12g. In one non-limiting embodiment, generally rigid member cavity 12g receives the attic staircase therein when the staircase is in a closed position. Alternative examples may be free of a staircase, such as when the supplemental cover 10 is placed atop member 12 placed above an attic scuttle opening.
In the example embodiment, when in the assembled position (
Elements of insulating and sealing member 12 are herein described relative to elements on supplemental cover 10. When viewed in cross section (
By way of non-limiting example, rigid insulating and sealing member 12 may be a Therma-Dome® commercially available for sale by Yankee Insulation Products, LLC of New Boston, N.H. Although the Therma-Dome®, is the preferred rigid member 12, clearly other commercially available rigid members configured to seal an attic opening 14 may be used.
Commercially available rigid insulating members are ordinarily lined with an insulating foil, which gives the generally rigid sealing member 12 an insulation value of about R-13. However, typically, many states set forth guidelines for a newly constructed or newly renovated attic to have an insulation value of about R-30, some states, such as Massachusetts, for example, have released weatherization assistance programs and technical manuals which suggest that attic insulation have an insulation value of at least R-38. The MASSACHUSETTS WEATHERIZATION ASSISTANCE PROGRAM TECHNICAL MANUAL recommends using a Therma-Dome® or equivalent (i.e., generally rigid insulating and sealing member 12) to be used whenever possible. See Page 60 of the MASSACHUSETTS WEATHERIZATION ASSISTANCE PROGRAM TECHNICAL MANUAL, the entirety of which is hereby incorporated by reference as if fully re-written herein and a copy of which may be obtained at https://masscap.files.wordpress.com/2010/04/wap-technical-manual-2008.pdf at the time of filing this disclosure.
Thus, when the state codes require or guidelines suggest a certain R-value for the attic, supplemental cover 10 has an R-value to meet those thresholds in order to ensure the system 1 R-value is similar to a surrounding attic floor R-value. In the non-limiting example stated above, if the surrounding attic R-value is R-38, supplemental cover 10 is filled with insulation so insulation system 1 has a resultant R-38 insulating value as well.

Additional components may be included to further accomplish the purpose of system 1. By way of non-limiting example, a shape retaining member (not shown), like a belt or even a skeleton frame, may be included with system 1 to surround and reinforce cover 10 to retain the intended shape of cover 10 when it is filled with insulation.
In accordance with one exemplary embodiment of the present invention, supplemental cover 10 is designed and configured to supplement and raise the total insulation value of the insulating ability of an existing attic insulating and sealing rigid member 12. Insulating and sealing member 12 atop opening 40 with a pull-down attic staircase ordinarily has an approximate R-13 insulative value. Cover 10 allows the homeowner to raise the R-value to R-30 or higher by covering the existing insulating and sealing member 12 and placing additional insulation 46 on all outside surfaces (sides, ends, and top) of the insulating and sealing member 12 within chamber 44 of supplemental cover 10. The combination of supplemental cover 10 with insulating and sealing member 12 will allow the insulating and sealing member 12 (which has a relatively low R-value and is insufficient to meet some building codes by itself) to be used in applications that require compliance with building codes that specify minimum R-value insulation over attic access that exceeds the R-value of the insulating and sealing member 12 by itself. Insulating and sealing member 12 includes a first insulating R-value and supplemental cover 10 for placing atop the sealing member includes a second insulating R-value larger than the first insulating R-value of insulating and sealing member 12. The first and second insulating R-values combine to achieve the desired R-value of system 1. In one example, a first insulating R-value of the insulating and sealing member 12 is less than about R-13 and a second insulating R-value of the supplemental cover 10 is greater than about R-30, achieving a cumulative insulative R-value of at least R-40 which meets most state building codes at the time of this disclosure.
In one particular embodiment, system 1 including cover 10 capping sealing member 12 has an insulating R-value that is at least R-38. In another example, system 1 may have a R-value (collectively cover 10 plus insulating and sealing member 12) as high as an R-45 rating, which is a significant improvement over the R-13 rating of member 12 alone. Notably, cover 10 of system 1 is preferably not a stand-alone solution to insulating an attic opening, however alternatively contemplated embodiments may be standalone devices. Further, cover 10 can be used to supplement the insulating value of other attic cover units, such as by way of non-limiting examples, a whole-house attic fan cover or an attic scuttle hole access cover.
In operation, a user must first prepare and ensure the attic floor 60 is level to accommodate rigid member 12. Rigid member 12 is placed on attic floor 60 such that bottom wall 12f engages the floor 60 and top panel 12a is upwardly facing. Cover 10 is placed over the top panel 12a of rigid attic insulating and sealing member 12, or over the Therma-Dome®. The top panel 12a of member 12 is aligned with cavity opening 38. Then a user applies a downward force to cover 10 so that member fits into cavity 40. The sidewalls 12b-e frictionally engage inner sidewalls 30, 32, and inner endwalls 34, 36 that define cavity 40. The rigidity of member 12 provides the base structure for the flexible embodiment of cover 10. In some embodiments, prior to fitting the cover 10 over member 12, an adhesive may be exposed so cover 10 sticks to member 12 when member 12 is nested within cavity 40.
Then a user fills cover 10 with insulation 46. When using roll insulation, a user may cut segments of the roll insulation to a desired length. As described above, a first set of two cut segments of roll insulation 46 have a width of about 15 inches and a length of about 62 inches. One of these two segments from the first set is inserted through slit 42 and maneuvered such that it is disposed between a sidewall 18 and inner wall 32 within the chamber 44. The second of these two segments from the first set is inserted through slit 42 and maneuvered such that it is disposed between sidewall 20 and inner wall 30 within the chamber 44. A second set of two cut insulation segments of roll insulation 46 have a width of about 15 inches and a length of about 46 inches. One of these two segments from the second set is inserted through slit 42 and maneuvered such that it is disposed laterally between endwall 22 and inner wall 36 within chamber 44. The second of these two segments from the second set inserted through slit 42 and maneuvered such that it is disposed between endwall 24 and inner wall 34 within chamber 44. A third set of three cut insulation segments of roll insulation 46 have a width of about 15 inches and a length of about 78 inches. Each of the cut segments are inserted through slit 42 and maneuvered such that they are disposed longitudinally side-to-side and positioned below top panel 16 and above the first set, the second set, and the upper inner panel 28 within chamber 44. Alternatively, when using blown insulation 46, a user may insert a hose 48 through slit 42 and pump insulation into chamber until full.
Once supplemental cover 10 has been filled with insulation, the assembled system 1 is placed over the attic opening 14. Bottom wall 12f engages attic floor 60 to create an air tight seal.
It is noteworthy that the present invention can be used to raise the insulative R-value of any space above an attic opening equal to that of the attic floor, not just a ladder for the attic access opening. The present invention may be broadly used with scuttle openings and any other openings to the attic regardless of their location, such as a side opening or a roof hatch.
In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.
Moreover, the description and illustration of the example embodiment of the invention are an example and the invention is not limited to the exact details shown or described.
