Abstract
An attic access covering kit features a cover panel, a perimeter seal running along a perimeter thereof to provide sealed closure against framing members in the ceiling that delimit the access opening, and a decorative frame sized to overlie the perimeter of the cover panel at an underside thereof and reach slightly outward therefrom. The cover panel is installed with the ceiling in an unfinished state, and interior finish work is performed on the ceiling around the installed cover panel, during which heat loss through the access opening is prevented by the cover panel and any insulation placed within the access opening thereover. After the finish work, is completed, the decorative frame is installed to cover the unfinished edges of the ceiling drywall around the access opening.
Description
KIT AND METHOD FOR SEALED COVERAGE OF AN ATTIC ACCESS OPENING
FIELD OF THE INVENTION
The present invention relates generally to solutions for covering an attic access opening in the ceiling of a building, and more specifically to a kit and method useful to provide both coverage thereof during the attic and ceiling finishing stages of the building construction, and an aesthetic final appearance once the finishing stages are completed.
BACKGROUND
Typical construction of an attic access door involves fastening of a wooden frame (or jamb) inside the ceiling between adjacent floor joists to delimit the attic access opening. Wood casing or trim is nailed to the underside of the jamb over the finished ceiling. A foam gasket is installed on the top edge of the jamb and an insulated box sits on top of that gasket to act as an openable/closeable door.
The box is typically made as a plywood box filled with fibreglass batting, or stacked blocks of rigid polystyrene insulation with a plywood sheet fastened to the underside of the stack.
To gain access to the attic, this insulated box is made 1/2-inch to 1-inch smaller than the cavity between the ceiling joists so that the insulated box can be pushed up through the cavity into the attic space. This 1/2-inch ยจ 1-inch gap between the insulated box and the ceiling joists has no insulation and can be very difficult to equip with a fully functioning seal, resulting in escape of air and vapours from the main interior space of the building to the attic space between the jamb and the ceiling joists.
In at least some jurisdictions, building code now requires the R-value (thermal resistance) of the covered access opening to be equivalent to the rest of the

The present invention relates generally to solutions for covering an attic access opening in the ceiling of a building, and more specifically to a kit and method useful to provide both coverage thereof during the attic and ceiling finishing stages of the building construction, and an aesthetic final appearance once the finishing stages are completed.
BACKGROUND
Typical construction of an attic access door involves fastening of a wooden frame (or jamb) inside the ceiling between adjacent floor joists to delimit the attic access opening. Wood casing or trim is nailed to the underside of the jamb over the finished ceiling. A foam gasket is installed on the top edge of the jamb and an insulated box sits on top of that gasket to act as an openable/closeable door.
The box is typically made as a plywood box filled with fibreglass batting, or stacked blocks of rigid polystyrene insulation with a plywood sheet fastened to the underside of the stack.
To gain access to the attic, this insulated box is made 1/2-inch to 1-inch smaller than the cavity between the ceiling joists so that the insulated box can be pushed up through the cavity into the attic space. This 1/2-inch ยจ 1-inch gap between the insulated box and the ceiling joists has no insulation and can be very difficult to equip with a fully functioning seal, resulting in escape of air and vapours from the main interior space of the building to the attic space between the jamb and the ceiling joists.
In at least some jurisdictions, building code now requires the R-value (thermal resistance) of the covered access opening to be equivalent to the rest of the
2 ceiling. To achieve this equivalent R-value, the insulated box often has to be built to a minimum height of 12-inches. As a result, the insulated box can be particularly heavy and awkward to push up through the cavity.
In the typical case where the attic has blown-in loose-fill insulation, when the insulated box or door is pushed up and placed into the attic space to enable access to the attic through the opening, the box or door has to sit on top of the blown-in insulation. This causes compression of the insulation, and a resulting reduction in the effectiveness thereof. The person exiting the attic space can attempt to fluff up the insulation to counteract its compaction by the door, however this can be a challenging task, particularly due to the need to hold the attic door in a balanced manner over the attic opening with one hand while using the other hand to try and re-fluff the insulation with the other hand.
Rather than temporarily placing the box on the insulation, one can alternatively raise the box up off the frame or jamb, and manually turn the box into an orientation in which it can be withdrawn down through the cavity and stored in the main interior space of the building until such time attic access is no longer required, at which time the box is lifted back up through the cavity and re-oriented into its seated position atop the frame or jamb. This approach may present some safety concern, specifically in that two hands are required to lift and reorient the bulky insulated box, creating a potential fall hazard for the person standing atop a ladder or other elevated structure to access the attic opening.
Typically the frames of attic access openings are made from wood, and usually not installed until the finish carpenter arrives to install the interior woodwork.

If the
3 building is being constructed during winter months, there is a considerable amount of heat loss through the opening, which results in unnecessary expense and potential damage to the attic insulation from frost build up within the attic. After the finish carpenter builds and installs the attic access door, the painter usually removes the door a couple weeks later for several days during painting which, also leaves the attic space open.
In view of the forgoing shortcomings, it is desirable to provide an improved solution for the coverage of attic access openings.

Figure 1 illustrates a fully installed cover assembly for an attic opening in __ a ceiling, as viewed in vertical cross-section.
Figure 2 is an exploded view of the cover assembly of Figure 1.
In the drawings like characters of reference indicate corresponding parts in the different figures.
DETAILED DESCRIPTION
Figure 1 shows a cover assembly 1 of the present invention in a fully installed state over an attic access opening 10 in a finished ceiling. The attic access opening 10 is rectangular in shape and delimited by a pair of parallel ceiling joists, the bottom edge of one of which can be seen at 12, and a pair of bridging or blocking members 14 (e.g. pieces of 2 x 4 lumber) perpendicularly spanning between the two __ ceiling joists at spaced apart positions therealong.

DETAILED DESCRIPTION
Figure 1 shows a cover assembly 1 of the present invention in a fully installed state over an attic access opening 10 in a finished ceiling. The attic access opening 10 is rectangular in shape and delimited by a pair of parallel ceiling joists, the bottom edge of one of which can be seen at 12, and a pair of bridging or blocking members 14 (e.g. pieces of 2 x 4 lumber) perpendicularly spanning between the two __ ceiling joists at spaced apart positions therealong. Each joist and each blocking member thus defines a respective one of the four sides of the rectangular access opening 10. Accordingly, the floor joists and bridging/blocking members in the ceiling define respective framing members that collectively define a framework or jamb of the attic access opening 10. A respective upright panel 16 (e.g. a piece of plywood __ sheeting) is fastened to each framing member 12, 14 at the side thereof facing into the access opening 10 so as to stand vertically upright over the full length of the framing member. These panels 16 define respective cavity walls that collectively delimit an attic access cavity 18 disposed immediately above the attic access opening 10. Loose-fill ceiling insulation 20 piled up in the attic space around the access cavity __ between the floor joists is prevented from spilling over the framing members into the
7 access cavity 18 by these cavity wall panels 16.
The cover assembly 1 features a main cover panel 22, a secondary panel 24, a decorative frame 26, and a perimeter seal 28, and is held in the fully installed position of figure 1 by way of threaded screw fasteners 30 driven into the framing members 12, 14 of the ceiling through aligned sets of fastener holes 32, 33, 34 in the main cover panel 22, secondary panel 24 and decorative frame 26.
The main cover panel 22 is a rectangular panel of slightly greater width and length than the attic access opening 10 so that placement of the cover panel 22 over the access opening with the perimeter of the cover panel 22 underlying the four framing members 12, 14 that surround the opening 10 will fully conceal the entirety of the opening 10 behind the cover panel 22. The perimeter seal 28, which may for example be closed-cell foam, is applied to the topside of the cover panel 22 (i.e. the side facing toward the ceiling) at, or a short distance inward, from the perimeter of the main cover panel 22 on all sides thereof so as to fully cover a perimeter-adjacent outer area of the cover panel 22. This way, the aforementioned placement of the cover panel 22 over the attic access opening 10 will sandwich the perimeter seal 28 between the cover panel 22 and the bottom edges of the framing members 12, 14 in the ceiling, thereby compressing the seal 28 to create or contribute to a sealed closure between the cover panel 22 and the framing members 12, 14.
A set of positioning blocks 36 stand upright from the topside of the main cover panel 22 just inwardly from the perimeter seal 28 for use as alignment guides during placement of cover panel 22 over the attic access opening. The blocks 36 are spaced apart such that a distance from the outer side of a first block (i.e.
the side thereof nearest the perimeter of the cover panel 22) to the outer side of a second block that lies opposite to the first block across a respective dimension of the panel is
The cover assembly 1 features a main cover panel 22, a secondary panel 24, a decorative frame 26, and a perimeter seal 28, and is held in the fully installed position of figure 1 by way of threaded screw fasteners 30 driven into the framing members 12, 14 of the ceiling through aligned sets of fastener holes 32, 33, 34 in the main cover panel 22, secondary panel 24 and decorative frame 26.
The main cover panel 22 is a rectangular panel of slightly greater width and length than the attic access opening 10 so that placement of the cover panel 22 over the access opening with the perimeter of the cover panel 22 underlying the four framing members 12, 14 that surround the opening 10 will fully conceal the entirety of the opening 10 behind the cover panel 22. The perimeter seal 28, which may for example be closed-cell foam, is applied to the topside of the cover panel 22 (i.e. the side facing toward the ceiling) at, or a short distance inward, from the perimeter of the main cover panel 22 on all sides thereof so as to fully cover a perimeter-adjacent outer area of the cover panel 22. This way, the aforementioned placement of the cover panel 22 over the attic access opening 10 will sandwich the perimeter seal 28 between the cover panel 22 and the bottom edges of the framing members 12, 14 in the ceiling, thereby compressing the seal 28 to create or contribute to a sealed closure between the cover panel 22 and the framing members 12, 14.
A set of positioning blocks 36 stand upright from the topside of the main cover panel 22 just inwardly from the perimeter seal 28 for use as alignment guides during placement of cover panel 22 over the attic access opening. The blocks 36 are spaced apart such that a distance from the outer side of a first block (i.e.
the side thereof nearest the perimeter of the cover panel 22) to the outer side of a second block that lies opposite to the first block across a respective dimension of the panel is
8 only slightly smaller than a corresponding dimension of the attic opening.
Accordingly, raising the cover panel 22 in a manner inserting the positioning blocks 36 into the attic access opening 10 will automatically place the perimeter seal 28 in proper alignment over the bottom edges of the framing members 12, 14. The illustrated embodiment features four positioning blocks (two of which are visible in the figures), each residing near a respective corner of the cover panel 22. In other embodiments, the positioning blocks may be omitted, in which case the installer may rely on visual alignment of the cover panel 22 over the framing members in the ceiling.
The ceiling features a layer of vapour barrier sheeting 38 installed over the bottom edges of the ceiling joists to block vapour transfer between the main interior space of the building and the attic space thereabove. This vapour barrier 38 is cut-out at the attic access opening 10, but extends far enough theretoward so as to fully cover, or least partially overlap, the bottom edges of the perimeter members 12, 14 that delimit the access opening 10. The vapour barrier 38 is secured, and preferably sealed, to the framing members 12, 14. For example, the vapour barrier may span fully across the bottom edges of the framing members 12, 14 and wrap up the inner sides thereof that face into the access opening, where suitable vapour barrier sealant secures the vapour barrier to the framing members in a vapour-tight manner around the full perimeter of the access opening 10. In such instances, the sealed closure between the cover panel 22 and the framing members 12, 14 therefore includes compression of the perimeter seal 28 of the cover panel 22 against the vapour barrier 38, plus the sealant-defined securement of the vapour barrier to the framing members. Even if the vapour barrier is not independently sealed and/or secured to the framing members, fastening of the cover panel 22 into place with the

Even if the vapour barrier is not independently sealed and/or secured to the framing members, fastening of the cover panel 22 into place with the
9 vapour barrier sandwiched between the cover panel's perimeter seal and the framing members may nonetheless provide a sufficiently effective vapour barrier and hermetic seal through the cooperation of the vapour barrier and perimeter seal.
Likewise, even if the vapour barrier doesn't overlap the coverage of the cover panel 22 in the above-described manner, compression of the seal 28 in direct contact against the framing members may nonetheless provide an improved vapour/air seal relative to conventional attic closure means.
The secondary panel 24 is equally or similarly sized to the main cover panel 22 in order to overlie the underside of the cover panel 22 (i.e. the side thereof opposite the ceiling) in a position mated with the decorative frame 26. The decorative frame 26 features four pieces of profiled moulding connected together end-to-end at right angles to delimit a rectangular opening of only slightly smaller length and width than the secondary panel 34. The profile of each moulding features a thicker outer portion 26a at the outer perimeter of the decorative frame and a thinner inner portion 26b at the inner perimeter of the decorative frame that delimits the rectangular opening thereof. The height differential between the inner and outer portions of each moulding is defined at least partially at the topside thereof, whereby the top profile of the decorative frame has a stepped shape that steps down in height toward the decorative frame's inner perimeter. The thinner inner portions 26b of the mouldings at this stepped down area of the decorative frame thus define a seat 40 atop which the secondary panel 24 resides in the completed assembly of Figure 1. The depth of the seat 40, i.e. the height differential between the inner and outer portions 26a, 26b of the decorative frame at the stepped topside thereof, equals or slightly exceeds the thickness of the secondary panel 24 so that the secondary panel doesn't act to space the decorative frame 26 outwardly away from the main covering panel 22 that is concealed behind the secondary panel 24 in the fully installed state of the assembly.
Having described the structure of the installed assembly of Figure 1, attention is now turned to its installation and use. The cover panel 22 and the decorative frame 26 are provided as separate components of a kit, which also 5 includes the secondary panel 24 and the perimeter seal 28. The threaded fasteners 30 may be included in the kit, or obtained separately. The perimeter seal 28 is preferably pre-attached to the cover panel 22 by the manufacturer, but alternatively could be applied to the cover panel 22 by the installer at the time of initial installation.

During construction of a building, with the framing of the building completed and the ceiling joists thus in place, but prior to finishing of the ceiling and insulating of the ceiling/attic, an installer fastens the bridging or blocking members 14 in place between the adjacent ceiling joists to form the boundaries of the attic access opening 10. At this point, the vapour barrier 38 is installed (or modified if already installed) so as to overlap or cover the bottom edges of the framing members 12, 14 while leaving the attic access opening 10 unobstructed, for example by cutting the vapour barrier along the perimeter of the attic access opening at the inner sides of the framing members 12, 14, and sealing or otherwise securing the vapour barrier thereto. With the vapour barrier 38 in place, the cover panel 22 and attached perimeter seal 28 are raised up into alignment over the attic access opening 10 and surrounding framing members 12, 14, and fastened in place by driving a first set of the threaded screw fasteners 30 into the framing members 12, 14 via the pre-defined fastener holes 32 provided in the cover plate at spaced apart locations around and

With the vapour barrier 38 in place, the cover panel 22 and attached perimeter seal 28 are raised up into alignment over the attic access opening 10 and surrounding framing members 12, 14, and fastened in place by driving a first set of the threaded screw fasteners 30 into the framing members 12, 14 via the pre-defined fastener holes 32 provided in the cover plate at spaced apart locations around and
11 near the perimeter of the cover plate. Tightened up against the framing members 12, 14 by the fasteners 30, the cover panel 22 compresses the perimeter seal 28 up against the vapour barrier 38 and underlying framing members 12, 14. The cover panel 22 is made of PVC or other vapour and air impermeable material, whereby the perimeter seal 28, the vapour barrier 38, and the impermeable cover panel 22 provide a vapour-tight closure of the attic opening 10, which in addition to preventing vapour transmission between the attic and main interior space, likewise blocks or limits airflow therebetween.
With the cover panel 22 in place, but the decorative frame 26 and secondary panel 24 not yet installed, drywall 42 or other interior finishing material can be installed on the ceiling. In the case of drywall installation, drywall sheets 42 are first fastened up against the bottom edges of the ceiling joists to cover the substantial majority of the ceiling, while leaving the attic access opening 10 uncovered.
That is, one or more of these drywalls sheets 42 is cut to an appropriate shape and size before installation so as to terminate short of the attic opening 10 in close proximity to the perimeter of the previously installed cover panel 22. Depending on the particular layout of drywall sheets to fit the room, this may be created by cutting a rectangular hole into a singular sheet of drywall with a hole-size slightly larger than the cover panel 22, or by cutting openings into perimeter edges of drywall sheets 42 that meet together around the attic access opening.
With the drywall sheets fastened to the ceiling joists in a manner leaving a drywall void on the ceiling at the previously installed cover panel 22, the cover panel is temporarily removed by disengaging the fasteners 30 from the framing members

With the drywall sheets fastened to the ceiling joists in a manner leaving a drywall void on the ceiling at the previously installed cover panel 22, the cover panel is temporarily removed by disengaging the fasteners 30 from the framing members
12, 14 to once again reveal the attic access opening 10. An insulation installer can then enter the attic space through the access opening 10 and apply blown-in loose-fill insulation 20 (or other insulation) to the attic space and ceiling in a manner filling the inter-joist cavities of the ceiling with the insulation 20. With this attic/ceiling insulating procedure completed, the insulation installer can exit the attic space via the access opening 10 currently unobstructed by the removed cover panel 22. During this exit from the attic space, the insulation installer fills the access cavity 18 and access opening 10 with fibreglass batt insulation 44, for example to a thickness achieving an equivalent R-value to the surrounding blown-in insulation 20.
At this point, with the insulation of the attic/ceiling complete, the cover panel 22 is re-installed in the same manner described above in order to re-close and re-seal the attic access opening 10 in a position underlying insulation-filled access cavity 18 With the drywall sheets having been previously fastened to the ceiling joists, and with additional drywall sheets likewise applied to any other drywall-intended walls of the room, taping and mudding of the drywall is then completed.
During the application and drying stages of this drywall finishing process, the installed position of the cover panel 22 and the sealed closure around the perimeter thereof blocks moisture-rich air from the drywall finishing processes from accessing the attic space. With the drywall installation complete, the ceiling (and any other paint-requiring walls) can be painted and allowed to dry, during which the installed cover panel 22 again blocks moisture-rich air from gaining access to the attic space. The ceiling is painted right up to the unfinished edges of the drywall that closely surround the installed cover panel 22.
When the paint has fully dried, the secondary panel 24 is seated atop the decorative frame 26, the combination of which is then installed over the cover panel 22, whereupon the outer portion 26a of the decorative frame at the outer periphery thereof resides outwardly from the perimeter of the cover panel 22 to overly

When the paint has fully dried, the secondary panel 24 is seated atop the decorative frame 26, the combination of which is then installed over the cover panel 22, whereupon the outer portion 26a of the decorative frame at the outer periphery thereof resides outwardly from the perimeter of the cover panel 22 to overly
13 the area at which the cover panel 22 and the drywall 42 closely meet so as to conceal the seam or gap between them, while the inner portion 26b of the decorative frame at the inner periphery thereof resides inwardly from the perimeter of the cover panel to conceal the perimeter of both panels and the respective fastener holes 32, 33 therein.
The edge of the drywall is thus concealed by the decorative frame 26, and the painted finish on underside of the ceiling drywall 42 extends continuously and seamlessly behind the outer portion 26a of the decorative frame. The profiled molding of the decorative frame provides a clean, finished, aesthetically pleasing border around the attic opening 10 and corresponding cover panel 22, which is likewise fully concealed by the secondary panel 24. The concealment of the cover panel 22 by the secondary panel 24 hides any scuffs, marks or other imperfections on the underside the cover panel 22, for example as may occur during the drywall and painting processes.
The secondary panel 24 may be materially distinct from the cover panel, and for example may be a pre-finished melamine panel of matching or similar colour to the decorative frame 26. Since the PVC cover panel forms a direct air/vapour barrier over the attic access opening 10, air/vapour impermeability is not essential at the secondary panel 24, and so lower cost materials may be used for the secondary panel.
The illustrated embodiment features respective sets of fastener holes 32, 33, 34 in the cover panel 22, secondary panel 24 and the decorative frame 26 that align with one another when the rectangular shapes of these components are aligned.
The fastener holes 32 in the cover panel 22 are countersunk at the underside of the cover panel 22, whereby a first set of flat-headed countersunk fasteners are used to directly hold only the cover panel 22 in place initially, with the tapered heads of the countersunk fasteners being recessed into the countersunk ends of the cover panel's fastener holes 32 so as not to interfere with placement of the secondary panel 24 in

The illustrated embodiment features respective sets of fastener holes 32, 33, 34 in the cover panel 22, secondary panel 24 and the decorative frame 26 that align with one another when the rectangular shapes of these components are aligned.
The fastener holes 32 in the cover panel 22 are countersunk at the underside of the cover panel 22, whereby a first set of flat-headed countersunk fasteners are used to directly hold only the cover panel 22 in place initially, with the tapered heads of the countersunk fasteners being recessed into the countersunk ends of the cover panel's fastener holes 32 so as not to interfere with placement of the secondary panel 24 in
14 flush abutment against the underside of the cover panel. The secondary panel and decorative frame, if not integrally-defined or factory-assembled, are mated together by the installer, and raised up to the already-fastened cover panel 22 in an aligned state matching up fastener holes 33, 34 in the secondary panel 24 and decorative frame 26 with the unused fastener holes in the cover panel 22. A second set of screws are driven through these aligned holes in the three components 22, 24, 26 into the framing members 12, 14 to secure the decorative frame 26 and secondary panel in place 24 to the cover panel 22, thereby also further reinforcing the already-fastened position of the cover panel 22.
The number of fastener holes 34 in the decorative frame 26 may be less than the number of fastener holes in the cover panel 22 such that there are no fastener holes in the decorative frame 26 at locations where corresponding fastener holes in the cover panel 22 are already occupied by the first set of fasteners that directly fasten only the cover panel 22 to the ceiling. Alternatively, the kit may comprise plugs for capping off select fastener holes in the decorative frame that are unavailable for use due to occupancy of the corresponding fastener holes in the cover panel by the first set of fasteners. In either case, no unoccupied holes in the decorative frame are visible, thereby ensuring a clean finished appearance.
The decorative frame may feature PVC moulding, though other materials can alternatively be used. For example, the decorative frame and/or =
secondary panel may be made of pre-finished or unfinished paintable/stainable wood.
While the illustrated embodiment features pre-defined fastener holes in each of the cover panel, secondary panel and decorative frame 26, other embodiments may lack such pre-defined fastener holes. However, pre-defined fastener holes help with proper fastener alignment to ensure engagement of the fasteners into the framing members. The illustrated hole positions align with the perimeter seal 28 of the cover panel 22 so that the fasteners 30 will penetrate through the seal 28, whereby the seal will conform around the fastener to maintain an optimal seal even where the fasteners penetrate the cover panel 22. In the case of a wood frame, predefined fastener holes 5 may not be necessary, and countersunk fastener heads can optionally be concealed with suitable filler, which can then be painted or stained to match the remainder of the decorative frame. However, white PVC moulding provides a durable, colour neutral, pre-finished frame requiring no on-site finishing steps. A white melamine secondary panel provides a cost efficient and close colour match to the white PVC
moulding of 10 the decorative frame.
