Description
BACKGROUND
[0001] Construction of buildings involves introduction of various
apertures, e.g., for passage of various penetrants including
utility/plumbing pipes. These apertures are potential sources of
entry of atmospheric or environmental substances, especially water.
Water has a natural tendency to travel rearwardly on the exterior
of a pipe for entry into the building. If water enters through an
exterior building wall, it can cause substantial damage.
[0002] In order to minimize the entry of substances, flashing may
be installed during construction. Flashing is the system used to
seal edges at walls, expansion joints, and other places where the
exterior envelope is interrupted or terminated. Most effective
flashing systems utilize the use of gravity, sealing tapes, or a
combination of both to drive away water from a wall. Flashing is
often made of rubber, tar, asphalt, synthetic polymers, or various
metals. Flashing devices used to prevent moisture from penetrating
seams are well known in the industry.
[0003] Currently, flashing electrical boxes, vents, and openings is
a multi-step process. Because of the nature of housewraps and felt
paper, there is no standard way of flashing openings in wall or
roof systems. Improper flashing practices result in water intrusion
towards the interior of a home, leading to water-/moisture-related
problems.
[0004] One current product, for example, is the flashing system
shown in FIG. 1B. This product is installed over sheathing 120 in
several steps: 1) A flange 112 with rubber seal gasket 114 seals
around the conduit 30 after installing housewrap, felt, or building
paper 140 beneath the lower half of the penetration. 2) The flange
112 is pushed flush against the wall 120. 3) The flange 112 is
nailed 116 at the top corners; and 4) housewrap, felt, or building
paper 140 is placed over the top half of the flange 112 to create a
natural water drainage plane.
[0005] Another flashing system is shown in FIG. 1A. The steps for
installing this can include 1) installing a penetrant 30 in the
sheathing 120; 2) applying flashing tape 214 around the penetrant
30; 3) placing housewrap, felt or building paper 140 over the
sheathing 120 but under the flashing 214 which is around and under
the lower half of the penetrant 30; and 4) applying housewrap, felt
or building paper 140 over the top half of the penetrant 30.
Another type of flashing is a "flap-type" system for non-standard
openings such as a faucet.
[0006] These processes are inefficient and laborious. There exists
a need for a simplified article, flashing system, and method for
providing flashing for openings in walls, roofs, and the like.
SUMMARY OF THE INVENTION
[0007] Described herein are articles and methods for flashing
openings in walls, roofs, and the like.
[0008] In one aspect, described herein is a flashing device. The
device can comprise a flange, a gasket, an opening, and an
adhesive. The device can comprise
(a) a flange comprising a front surface, back surface, and an
opening, wherein the opening is essentially centrally located in
the flange and wherein the flange is suitable for attachment to a
surface of an overlaid structural sheathing panel over a protrusion
through the sheathing panel, (b) a gasket effective to essentially
seal the perimeter of the protrusion to water, and (c) an adhesive
backing located on a back surface of the flange wherein the backing

Optionally, the device can comprise an intermediate layer between
the flange and the adhesive backing.
[0009] In another aspect, described herein is a building system or
kit comprising an overlaid wood composite panel and a flashing
device of the invention. The system or kit can comprise (a) a
flashing device comprising a flange comprising a front surface,
back surface, and an opening, wherein the opening is essentially
centrally located in the flange and wherein the flange is suitable
for attachment to a surface of an overlaid structural sheathing
panel over a protrusion through the sheathing panel,

protrusion to water, and an adhesive backing located on a back
surface of the flange wherein the backing comprises an adhesive
effective to permanently attach the flashing device to the surface
of the overlaid structural sheathing panel, and (b) an overlaid
structural sheathing panel.
[0010] In a further aspect, described herein is a method of
flashing penetrations comprising adhesively attaching to an
overlaid structural sheathing panel
a flashing device comprising (i) a flange comprising a front
surface, back surface, and an opening, wherein the opening is
essentially centrally located in the flange and wherein the flange
is suitable for attachment to a surface of an overlaid structural
sheathing panel over a protrusion through the sheathing panel, (ii)
a gasket effective to essentially seal the perimeter of the

[0011] Additional advantages will be set forth in part in the
description which follows, and in part will be obvious from the
description, or may be learned by practice of the aspects described
below. The advantages described below will be realized and attained
by means of the elements and combinations particularly pointed out
in the appended claims. It is to be understood that both the
foregoing general description and the following detailed
description are exemplary and explanatory only and are not
restrictive.
BRIEF DESCRIPTION OF THE DRAWINGS
[0012] The accompanying drawings, which are incorporated in and
constitute a part of this specification, illustrate several aspects
described below. Like numbers represent the same elements
throughout the figures.
[0013] FIG. 1 shows several different types of installed flashing
from a vertical cross-sectional view of a wall. A=use of flashing
tape; B=Quickflash (Quickflash Weatherproofing Products, Inc..RTM.,
Las Vegas, Nev.) flashing system; C=an embodiment of a flashing
device of the current invention.
[0014] FIG. 2 shows an embodiment of a flashing device of the
current invention.
DETAILED DESCRIPTION
[0015] Before the present articles, devices, and/or methods are
disclosed and described, it is to be understood that the aspects
described below are not limited to specific example embodiments,
specific embodiments may, of course, vary. It is also to be
understood that the terminology used herein is for the purpose of
describing particular aspects only and is not intended to be
limiting.
[0016] In this specification and in the claims which follow,
reference will be made to a number of terms which shall be defined
to have the following meanings:
[0017] It must be noted that, as used in the specification and the
appended claims, the singular forms "a," "an," and "the" include
plural referents unless the context clearly dictates otherwise.
Thus, for example, reference to "an adhesive" includes mixtures of
adhesives; reference to "a polymeric material" includes mixtures of
two or more such materials, and the like.
[0018] "Optional" or "optionally" means that the subsequently
described event or circumstance may or may not occur, and that the
description includes instances where the event or circumstance
occurs and instances where it does not.
[0019] Ranges may be expressed herein as from "about" one
particular value, and/or to "about" another particular value. When
such a range is expressed, another aspect includes from the one
particular value and/or to the other particular value. Similarly,
when values are expressed as approximations, by use of the
antecedent "about," it will be understood that the particular value
forms another aspect. It will be further understood that the
endpoints of each of the ranges are significant both in relation to
the other endpoint, and independently of the other endpoint.
[0020] For purposes of this application, the term "overlaid" panel
will refer either to panels used for walls, roofs, or other uses.
Traditionally, "overlaid" refers to walls and "roof underlayment"
generally applies to roofs; however, for ease of usage herein "an
overlaid panel" is any panel with an overlay attached, e.g.,
ZIP.TM. Wall or Roof Sheathing, whether used as wall or roof since
structurally they are considered sufficiently similar in the
context of flashing.
[0021] A device is described herein which is used as flashing on
openings in walls, roofs, and the like. The device comprises a
flange, a gasket, an opening, and an adhesive.
[0022] Also disclosed is a method of installing a flashing system
on an aperture within structural sheathing by, e.g.,:
a. "locking and sealing" the diameter of a penetrant, such as a
pipe, located within an aperture in structural sheathing with a
rubber seal gasket, b. sealing a flange comprising the gasket
against the structural sheathing with a self-adhesive backing.
[0023] Use of a flashing device of the invention can eliminate the
need for steps of using a secondary tape or caulking to seal around
a penetration/penetrant and/or fastening a flashing flange with
mechanical type fasteners, e.g., nails or staples. Further, the
device can eliminate layering of housewrap, etc. over and under a
flashing device.
[0024] A device of the invention can complement, for example, the
ZIP System.TM. (wall and roof) product line (Huber Engineered Woods
LLC, Charlotte, N.C.; www.huberwood.com;
http://huberwood.com/)--the invention can provide easier flashing
installation compared with current traditional felt, building
paper, or housewrap, essentially transforming a multi-step flashing
process into a one-step flashing process.
A. Articles
[0025] A flashing device of the current invention allows for one
step flashing without the need for additional securing means (e.g.,
nails, staples, or caulk) and without the need to overlap/layer the
flashing with building paper or housewrap of any sort. However,
either additional securing means or building paper/housewrap or
both could also be used with the device, if desired.
[0026] In one aspect described herein are articles for flashing
openings in walls, roofs, and the like. A flashing device 10 of the
invention can comprise a flange 12, a gasket (e.g., rubber gasket)
14, and an adhesive (e.g., a self-adhesive) backing 16. See, e.g.,
FIG. 2 for an example embodiment. The device can be used, for
example, in combination with structural sheathing with built-in
water-resistive barriers (or built-in roof underlayment) such as
the ZIP.TM. Wall or Roof system, described in, e.g., in U.S. Pat.
Nos. 6,737,155 and 6,772,569 and U.S. Published Applications
2005/0229504, 2005/0257469, and 2005/0229524, hereby incorporated
by reference for their teachings on overlaid building panels. The
device can be used on other construction panels or materials as
well, e.g., coated panels, insulation board, panels with
post-manufacture applied coatings (e.g., spray or trowel-applied
water-resistive barriers), etc.
[0027] Referring to FIG. 1C, an installed embodiment of a flashing
device 10 is shown. FIG. 1C illustrates a device 10 in place on a
pipe 30 installed on an overlaid panel wall 20. The device 10 has a
gasket 14 with an opening 18 sized to permit passage of a pipe 30
therethrough and sufficiently small to snugly surround the pipe 30
such that an essentially water-tight seal at the interface of the
pipe 30 and the gasket 14 is formed. A flange 12 surrounds the
gasket 14, and preferably is a plastic flange 12 with the gasket 14
centrally disposed therein, as shown. Such configuration can be
achieved by differing processes such as injection molding insert
techniques or by adhesively securing the gasket 14 to the flange 12
across a pre-formed opening 18 in the flange 12.
[0028] An adhesive backing 16 seals the device 10 to an overlaid
wall panel 20, thereby making the device 10 an integral permanent
component of the wall 20. When water travels rearwardly on the
exterior of the pipe 30 from its opening, the water simply
encounters the gasket 14 in sealing engagement with the exterior
surface of the pipe 30. Because the water can travel rearwardly no
further, it simply flows downwardly by gravitational force over the
flange 12 and to the ground.
[0029] Final finishing material such as siding, brick, stucco
through which the pipe 30 projects is applied directly on and over
the device 10, thereby making the device 10 an integral component
of the wall 20 for the life of the building structure.
[0030] Installation of a flashing device of the invention on a roof
would be very similar. Final finishing material for roof can
include shingles, tile, metal, and the like.
[0031] A flange 12 of the device can comprise a material
substantially impervious to water, for example, a polymeric
material (e.g., plastic, vinyl, etc.), metal (e.g., galvanized
steel), or resinated paper. The material is preferably flexible but
with rigidity effective to retain its shape. The shape of the
flange is not critical; any shape which is effective for preventing
atmospheric penetration of the opening can be used. For example, in
FIG. 2, the flange is generally rectangular in shape, more
particularly, square. One of ordinary skill in the art in the art
can determine an effective shape. The flange comprises a front
surface 12a and a back surface 12b (not shown). The flange is
preferably made of a one-piece unitary sheet material and is
substantially planar in order to fit essentially flush to a wall,
roof, or other surface in which the penetration is found. However,
if the surface to which the flange is to be attached is not planar,
then the flange need not be planar. The size of the flange is one
which is effective for preventing atmospheric penetration of the
opening. One of ordinary skill in the art in the art can determine
an effective size. For example, one example embodiment has
dimensions of 8'' W.times.8'' L.times.1/8'' thick. The flange can
be formed by methods known to one of ordinary skill in the art such
as by molding or extruding.
[0032] Within the flange 12 is an opening 18. The opening 18 is
preferably essentially centrally located within the flange 12. The
size of the opening is effective to receive a protrusion
therethrough, e.g., a pipe. One example embodiment of the device
has a 3'' diameter circular opening. The opening is to be placed
over a penetrant in a roof, wall, or the like. The opening can,
e.g., be essentially circular in shape, though the shape is not
critical. A variety of shapes and sizes of openings can be provided
in order to accommodate various protrusions.
[0033] A gasket 14 can comprise a polymer, e.g., a plastic film or
a polymeric elastomeric material, for example, rubber, nitrile,
EPDM, polyurethane, polyurea, mixtures therof, copolymers thereof,
and the like. Further, the gasket can comprise a solid or porous
material, e.g., closed-cell foam. The gasket is intended to fit
snugly around the protrusion. The gasket is oriented substantially
in the same plane as the flange but is flexible and when installed
will likely deform outside the flange plane. The gasket can be any
element of the device which is effective for preventing atmospheric
penetration of the opening. One of ordinary skill in the art can
determine an effective gasket. The gasket 14 can be an elastomeric
material with an opening 18 sized to permit passage of a
penetrant/protrusion (e.g., pipe 30) therethrough and sufficiently
small to snugly surround the penetration/protrusion such that an
essentially water-tight seal at the interface of the
penetration/protrusion and the elastomeric material is formed, for
example, having a 2'' diameter circular opening. Rubber and plastic
film having such elastomeric properties are two examples of usable
elastomeric material.
[0034] The gasket 14 can be sized and shaped to be simply fitting
within the opening 18 in the flange 12, e.g., as shown in FIG. 2,
or can be differently sized and shaped. For example, the gasket can
be formed in essentially the same size and shape as the flange but
for the size of the opening therein. In an embodiment where the
flange and gasket have similar sizes and shapes, the gasket would
form an intermediate layer between the flange and the adhesive
backing.
[0035] An adhesive backing 16 can, for example, be a
pressure-sensitive self-adhesive backing. The adhesive backing 16
serves to adhere the flashing device 10 to a wall 20, roof, or the
like. The adhesive can comprise any adhesive which is effective for
preventing atmospheric penetration of the opening and an effective
adhesion between the flange 12 and the wall 20. For example, in an
example embodiment, the adhesive can be acrylic, butyl, rubber,
polyurethane or urethane, silicone, epoxy, latex, anaerobic,
cyanoacrylate, asphaltic, oleoresinous, nitrile, or polysulfide.
Examples of adhesives used in construction can be found in Handbook
of Adhesives and Sealants in Construction, Amstock, Joseph S.,
2001, McGraw-Hill, New York. Choice of adhesives for use on an
overlaid wood composite panel can be more flexible than many other
surfaces due to the character of an overlay, e.g., the overlay
found on ZIP.TM. sheathing. One of ordinary skill in the art can
determine an effective adhesive and an effective amount of adhesive
to use. The adhesive can be applied to the device using
conventional methods, such as spray coating or application with a
roller.
[0036] The flashing device 10 can be assembled by, e.g., adhesively
bonding the gasket to the flange or by injection molding insert
techniques of forming the gasket within the flange. The flange,
gasket, and adhesive backing can be manufactured using conventional
methods; one of skill in the art can determine how to manufacture
the components and combine them together.
[0037] The flashing can be adhesively attached to a surface, e.g.,
of a wall. It will be understood by one of ordinary skill in the
art that the present flashing device can vary widely in many shapes
and sizes commensurate with the dimensions of the conduit access
hole and service required, e.g., conduit, gas line, drainage line,
duct work and the like.
System
[0038] A system of the invention can comprise an overlaid wood
composite panel. In particular, an example wood composite is
oriented strand board, such as described in U.S. Pat. Nos.
5,525,394 and 5,635,248, herein incorporated by reference in their
entireties. Embodiments of systems of the invention can comprise
conventional wood composite panels as well as specialty panels such
as the ZIP System.TM. overlaid panels (described in, e.g., in U.S.
Pat. Nos. 6,737,155 and 6,772,569 and U.S. Published Applications
2005/0229504, 2005/0257469, and 2005/0229524), coated panels, and
the like.
[0039] A system of the invention preferably comprises a wood
composite panel with an integral water-resistive
barrier/underlayment and a flashing device as described above.
[0040] The invention can include a kit comprising an overlaid wood
composite panel (such as those described in, e.g., in U.S. Pat.
Nos. 6,737,155 and 6,772,569 and U.S. Published Applications
2005/0229504, 2005/0257469, and 2005/0229524) and a flashing device
of the invention as described above. The kit can comprise a
plurality of flashing devices of varying shapes, sizes, and opening
sizes, for example.
B. Methods
[0041] The articles described above can be manufactured using known
methods to one of ordinary skill in the art. For example, the
device can be molded. In another example method, the flange and
gasket can be stamped out of a sheet material, including the center
hole in each. The gasket can then be applied to the flange using an
adhesive, e.g., manually using a hand roller or automatically using
automatic dispensing and application equipment. The self-adhesive
backing can be applied by coating, such as by a hand roller or
automatic application equipment. Optionally, the adhesive backing
can be provided with a release film applied to the adhesive
backing. If a release film is applied, it can be stamped out of a
sheet release liner material and then applied to the self-adhesive
backing. Another example method of manufacturing would be to layer
the adhesive backing between release films in roll form using
suitable means (e.g., roll-coating, curtain coating) then stamp out
the layered release film-backing in the same shape as the flange.
In this method, one release film is removed from the adhesive
backing to be applied to the flange, with pressure, leaving the
second release film to be removed from the adhesive backing by an
installer.
[0042] The invention includes a method for flashing an opening
comprising installing a device of the invention over an opening or
penetration in a structural sheathing panel and sealing the device
to the structural sheathing panel. The gasket and opening of the
device fits over any penetrant through the opening or penetration.
The method can further comprise providing an overlaid wood
composite panel as the structural sheathing panel, preferably a ZIP
System.TM. panel as described above.
[0043] A method of installing a flashing system on apertures can
comprise
a. placing a flashing device of the invention over a penetrant,
such that the exterior (e.g., diameter) of the penetrant, such as a
pipe, is sealed with the gasket of the device, and b. sealing the
device against the structural sheathing panel with a self-adhesive
backing of the device.
[0044] Throughout this application, various publications are
referenced. The disclosures of these publications in their
entireties are hereby incorporated by reference into this
application in order to more fully describe the compounds,
compositions and methods described herein.
[0045] Various modifications and variations can be made to the
compounds, compositions and methods described herein. Other aspects
of the compounds, compositions and methods described herein will be
apparent from consideration of the specification and practice of
the compounds, compositions and methods disclosed herein. It is
intended that the specification and examples be considered as
exemplary.
