FIELD OF THE INVENTION
[0002] The invention is directed to removal of moisture from the
wall, floor, and/or roof of a building.
BACKGROUND OF THE INVENTION
[0003] In building construction (residential and/or commercial),
moisture removal from within a wall, floor, and/or roof is an
important consideration. Failure to adequately remove moisture can
lead to adverse consequences, for example, mold and/or rot. Some
contemporary solutions are to promote airflow, ventilation, and
drainage within the wall floor, and/or roof by, for example, the
use of an entangled net product. The air movement is used to move
any moisture out of the wall, floor, and/or roof. A typical wall
may include: a frame (e.g., studs/plates, rafters, joists) with a
sheathing (e.g., OSB, foam board, plywood) affixed to the frame, a
moisture barrier (e.g., house wrap) covers the sheathing, an
entangled net overlays the moisture barrier and with vents in fluid
communication with the entangled net, and a veneer (e.g., brick,
stucco, siding) finishes the wall.
[0004] There is a need for new products and methods for
facilitating ventilation, moisture removal, and drainage in a wall
floor, and/or roof.
DESCRIPTION OF THE DRAWINGS
[0005] For the purpose of illustrating the invention, there is

precise arrangements and instrumentalities shown.

SUMMARY OF THE INVENTION
[0014] A method for facilitating ventilation and/or drainage in a
building wall, floor, and/or roof by the step of: placing a foam
insulation board with an interior board face and an exterior board
face, at least one board face having ventilation and/or drainage
grooves and/or protrusions into the building wall, floor, and/or
roof; providing vents in the building wall, floor, and/or roof
adjacent end portions of the insulation board, whereby ventilation
is facilitated within the wall, floor, and/or roof of the building
by air moving through the vents, along the grooves and/or
protrusions of the foam insulation board, and out of the vents,
drainage of water is facilitated within the wall or the roof of the
building by a pathway created by the grooves and/or protrusions,
and moisture removal is facilitated by the passage of air during
ventilation.
Description of the Invention
[0015] Referring to the figures, the ventilated and draining foam
insulation panel for a wall, floor, and/or roof is illustrated.
[0016] FIG. 1 shows a wall 10, parts broken away for clarity (the
invention is not limited to wall, as discussed below). Wall 10
shows frame 12 (having studs and plates) with a conventional
interior cladding 11 (e.g., drywall, paneling), a conventional
sheathing 14 (e.g., OSB, foam board, plywood), an optional, but
preferred, a conventional moisture barrier 18 (e.g., house wrap),
foam insulation panel 50, a veneer (or exterior cladding) 16, an
vents 70.
[0017] FIG. 2 is a schematic illustration of an embodiment of a
cross-section of a wall system 10 on a foundation 20. The wall
system 10 generally includes: a frame 12, a sheathing 14 affixed to
the frame 12, a foam insulation panel 50 (discussed in greater
detail below) affixed over the sheathing 14, and a veneer 16 (e.g.,
brick, stucco, siding). Optionally, the wall system 10 may include
a vapor barrier (e.g., house wrap), not shown, but conventionally
located, for example, between the sheathing 14 and the foam
insulation 50. FIG. 3 is a schematic illustration of an embodiment
of a cross-section of a roof system 30. The roof system 30
generally includes: a frame 32 (e.g., rafters), a sheathing 34
(e.g., roof deck) affixed to the frame 32, a foam insulation panel
50 (discussed in greater detail below) affixed over the sheathing
34, and a veneer 36 (e.g., shingles). Optionally, the roof system
30 may also include a moisture barrier (e.g., tar paper), not
shown, but conventionally located, for example, between the
sheathing 34 and the foam insulation 50. FIG. 4 is a schematic
illustration of an embodiment of a cross-section of a floor system
40 (e.g., an attic floor is illustrated). The floor system 40
generally includes: a frame 42 (e.g., joists), a sheathing 44
(e.g., subfloor) affixed to the frame 42, a foam insulation panel
50 (discussed in greater detail below) affixed over the sheathing
44, and, optionally, a veneer 46 (e.g., flooring). Optionally, the
floor system 40 may also include a moisture barrier (e.g., house
wrap), not shown, but conventionally located, for example, between
the sheathing 44 and the foam insulation 50. The foregoing is not
limiting on the invention, and those of ordinary skill will readily
understand the application of the invention.
[0018] Hereinafter, the foam insulation panel (or foam panel) 50
will be discussed.
[0019] The foam insulation panel (or board) 50 facilitates
ventilation, moisture removal, and drainage within the wall 10,
floor 40, and/or roof 30 via a plurality of vertical grooves (or
pathways formed by protrusions), discussed in greater detail below.
These grooves (or pathways) allow air to move through the vents in
the wall, floor, and/or roof systems, along the grooves (or
pathways), and out of the vents, allow drainage of water by the
grooves or pathways, and moisture removal by the passage of air
during ventilation. Additionally, the foam insulation panel (or
board) will impact the thermal insulation value (R) of the foam
board and the wall 10, floor 40 or roof 30 systems.
[0020] The foam insulation board 50 has an interior board face 52
and an exterior board face 54 and at least one face has ventilation
and/or drainage grooves 56 and/or protrusions 58, see FIGS. 5-7.
The foam board 50 may have grooves 56 and/or protrusions 58 on both
faces of the board, see FIGS. 1 and 8. The grooves 56 and/or
protrusions 58 are used to create space to facilitate the removal
of moisture. Additionally, the foam board 50 may have a thermal
foil 60 affixed to, all or part of, he interior face, exterior
face, or both, discussed below.
[0021] FIG. 5 illustrates one face of the foam board 50 with a
plurality of protrusions 58 (e.g., cylindrical shown, but not so
limited). FIG. 6 illustrates one face of board 50' with a plurality
of concave grooves 56 (e.g., hemi-cylindrical, but not so limited).
FIG. 7 illustrates one face of board 50'' with a plurality of
convex grooves 56 (e.g., hemi-cylindrical, but not so limited).
FIGS. 1 and 8 illustrate a foam board with grooves, on both sides
of the foam board 50. In FIG. 1 the grooves on each face run in the
generally horizontal and generally vertical directions. In FIG. 8,
the grooves on each face run in one direction. In the foregoing
description of the foam board 50, certain shapes of the protrusions
or grooves are mentioned, but those shapes are non-limiting and any
shape is possible, so long as the shape facilitates removal of
moisture from within the wall.
[0022] The foam board 50 may have a density in the range of about
15-60 Kg/m.sup.3. The foam board 50 may have a groove depth (or the
protrusion height) in the range of about 0.125-0.75 inches,
preferably about 0.15-0.35 inches, most preferably about 0.25
inches. The foam board may have a thickness in a range of about 1-6
inches, preferably about 2-4 inches. The foam board may be any foam
material. The foam board may be a closed cell foam. The foam board
may have a moisture impervious and/or thermally impacting skin.
[0023] The thermal foil 60, one embodiment shown in FIG. 8, shows a
cross-section of the foam board with a thermal foil on both sides
thereof. The thermal foil 60 may be any thermal foil that can raise
or lower the R value of the board and/or the wall, floor, or roof
system. In one embodiment, the thermal foil 60 may be a reflective
(e.g., metalized or aluminized) foil. In theory, the reflective
foil may replenish the R value of the lost because of the grooves
or channels placed in the foam board.
[0024] The vents 70 are conventional and may be located along the
terminal ends of the foam board 50 so that moisture-laden air may
flow through the vents and the grooves/protrustions of the foam
board and out another vent.
[0025] In operation, ventilation is facilitated within the wall,
floor, and/or roof of the building by air moving through the vents,
along the grooves and/or protrusions of the foam insulation board,
and out of the vents, drainage of water is facilitated within the
wall or the roof of the building by a pathway created by the
grooves and/or protrusions, and moisture removal is facilitated by
the passage of air during ventilation.
[0026] The present invention may be embodied in other forms without
departing from the spirit and the essential attributes thereof,
and, accordingly, reference should be made to the appended claims,
rather than to the foregoing specification, as indicating the scope
of the invention.
