Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] The present application claims priority to U.S. Provisional
Patent Application No. 61/376,575 ("the '575 application"), which
was filed on Aug. 24, 2010, and entitled "Fiber Matting". The '575
application is incorporated by reference into the present
application in its entirety.
FIELD
[0002] The present disclosure relates to materials that may be used
in the roofing industry. More specifically, the disclosure relates
to a fiber matting strip used to provide ventilation in roofs or
other building components.
BACKGROUND
[0003] It is common to ventilate roofs of building structures to
remove stagnant or hot air, with such ventilating systems sometimes
including vents in the gables of the building structure, along the
soffits or along the ridge or apex of the roof. The vents are
provided to permit the ingress and egress of air and when the vent
is along the ridge, the air naturally egresses through the vent
from beneath the roof by convection. Ridge vents are typically
combined with gable or soffit vents through which air can flow into
the space below the roof to encourage a continuous flow of air from
the ambient environment, through the space beneath the roof and
back to the ambient environment through the ridge vent.
[0004] One problem with vents which simply consist of openings in a
building structure through which air can readily pass is that
insects, rain or other undesirable elements can also pass through
the openings. In addition, venting materials are typically precut
to fit a specific roof profile or use.
[0005] Due to this aspect of venting materials, the dimensions of
the roof profile must typically be measured or known prior to the
specific material being ordered or purchased. Once these
measurements are acquired, the appropriate size of venting material
may be ordered from a vendor. Provided no errors are made in the
measurements or other steps of the ordering process, a vent of the
appropriate size may be installed for the specified roof profile or
use.
SUMMARY
[0006] Disclosed herein is a roofing ventilation system component.
In one embodiment, the component includes a fiber matting strip of
air-permeable compressible nonwoven fibers and a thermoplastic
polymer binding agent. The fibers may be polyester and nylon. The
fiber matting may be installed in connection with a ridge vent,
roof rafters and a fascia, or hip or ridge shingles.
[0007] Disclosed herein is a method of installing a roofing
ventilation system component. In one embodiment, the method
includes applying a fiber matting strip of nonwoven material and a
thermoplastic polymer binding agent to a first roof surface, the
strip of nonwoven material substantially conforming to a surface of
the first roof surface; and optionally securing the strip to the
first roof surface. In some embodiments, the method may further
include applying the fiber matting strip to a second roof surface
that is adjacent to the first roof surface. The strip may be
secured to the second roof surface. A ridge cap may then be
fastened to the first roof surface and the second roof surface.

embodiments of the present invention will become apparent to those
skilled in the art from the following Detailed Description, which
shows and describes illustrative embodiments of the invention. As
will be realized, the invention is capable of modifications in
various aspects, all without departing from the spirit and scope of
the present invention. Accordingly, the drawings and detailed
description are to be regarded as illustrative in nature and not
restrictive.
DETAILED DESCRIPTION
[0015] The present disclosure describes a fiber matting that may be
used as a component of a roof ventilation system. The fiber matting
may help to provide ventilation in a roof by allowing air to pass
through and may be used under roofing, under hip/ridge shingles or
as an exhaust/intake fascia vent, thereby allowing air to pass
between the exterior and the interior of a house or other building.
In one embodiment, the fiber matting may be a nylon fiber matrix
bound together by a thermoplastic polymer or polyester binding
agent. In one embodiment, the binding agent is "vycar x 58", which
is a composition including polyvinyl chloride with aluminum tri
hydrate (ATH) added as a fire retardant. In one embodiment, the
fiber matting may be a strip of compressible, non-woven,
non-wicking, fiber-based modified polyester matting. The fiber
matting is configured to act as a barrier to entry of moisture,
insects or dust and may also reduce mold build-up. In some
embodiments, the matting also does not include an external baffle
or fabric wrap, thus reducing the amount of snow or dirt that may
be trapped therein. The fiber matting strip may be installed
without the use of dedicated segments that are adapted to fit a
specific roof profile.
[0016] As shown in FIG. 1A, a fiber matting strip 100 may be
installed along a roof panel 104 having an uneven surface 108. As
indicated in FIG. 1B, the strip 100 is installed across the ridge
cap such that at least a portion of the strip 100 is in contact
with each roof panel 104a, 104b. In some embodiments, the roof
panels 104 may be a corrugated sheet. The strip 100 may be
installed across both raised 112 and recessed 116 portions of the
uneven surface 108. Across the raised portions 112, the strip 100
compresses and forms around the surface 108. Across the recessed
portions 116, the strip 100 may expand or remain the same size to
keep in contact with the surface 108. Thus, substantially
continuous contact is maintained between the strip 100 and both
raised 112 and recessed 116 portions of the uneven surface 108.
This continuous contact is maintained without dividing the strip
100 into separate segments that are dedicated to engaging different
portions of an uneven surface 108.
[0017] As can be understood from FIGS. 1B and 1C, the strip 100 may
be installed between major and minor roof panels in a ridge portion
of a roof. In one embodiment, the strip 100 may be deployed as a
seal between a first (or major) roof panel or surface (e.g. a
corrugated sheet) 104a, a second (or major) roof panel or surface
(e.g. a corrugated sheet) 104b, and a ridge cap 120 (minor roof
panel). In some embodiments, the strip 100 may be applied to the
first roof panel 104a and the second roof panel 104b as a
continuous sheet. In other embodiments, the strip 100 may be cut
into pieces of appropriate length and installed on a respective
roof section. The strip 100 may be secured by a fastener, such as a
nail, a screw or a clip or an adhesive. As indicated in FIG. 1B,
the strip 100 is installed across the ridge cap such that at least
a portion of the strip 100 is in contact with each roof section
104a, 104b. The strip 100 provides a tight seal between the uneven
surface of corrugated sheet 104 and the ridge cap 120. The nonwoven
material that makes-up the strip 100 allows for air to pass through
the strip 100, thereby allowing ventilation to occur between the
corrugated sheet 104 and the ridge cap 120.
[0018] As shown in FIG. 2A, in some embodiments, a fiber matting
strip 100 may be installed along a roof section or surface 204a,
204b of a composition roof. As indicated in FIG. 2B, the strip 100
is installed across the ridge cap such that at least a portion of
the strip 100 is in contact with each roof section 204a, 204b. The
roof section 204 may have an uneven surface and the strip 100
compresses and forms around or in the surface as needed to keep in
substantial contact with the roof section 204. This continuous
contact is maintained without dividing the strip 100 into separate
segments that are dedicated to engaging different portions of the
roof section 204.
[0019] As can be understood from FIGS. 2B and 2C, the strip 100 may
be installed across adjacent roof sections in a ridge portion of a
roof. In one embodiment, the strip 100 may be deployed as a seal
between a first roof section or surface 204a, a second roof section
or surface 204b and a ridge cap 220. In some embodiments, the strip
100 may be applied to the first roof section 204a and the second
roof section 204b as a continuous sheet. In other embodiments, the
strip may be cut into pieces of appropriate length and installed on
a respective roof section. The strip may be secured by a fastener,
such as a nail, a screw or adhesive. The strip 100 provides a tight
seal between the potentially uneven surface of roof sections 204a,
204b and the ridge cap 220. The nonwoven material that makes up the
strip 100 allows for air to pass through the strip 100, thereby
allowing ventilation to occur between the respective roof sections
204a, 204b and the ridge cap 220.
[0020] As indicated in FIGS. 1B-1C and 2B-2C, the strip 100 may be
installed at an intake or an exhaust portion of a roof ventilation
system, such as the ridge cap location shown in FIGS. 1B-1C and
2B-2C. The use of polyester or other fibers in the strip 100
prevents water or moisture from being wicked into the strip 100. By
preventing moisture from accumulating in the strip 100, the strip
100 is prevented from freezing. If the strip 100 were allowed to
freeze, it could lose its air-permeability and cease to function as
a ventilation component. In connection with the roof cap
installation shown in FIGS. 1B-1C and 2B-2C, the strip 100 may be
adapted to provide a low profile or an otherwise inconspicuous
appearance. For example, the strip 100 may be grey in color. In one
embodiment, the strip 100 may be sized to seal an approximate one
to two-inch gap between the corrugated sheet 104 and the ridge cap
120 or the roof panel 204 and the ridge cap 220.
[0021] In other embodiments for use in connection with a fascia, as
shown in FIG. 3, the fiber matting strip 100 may be installed in a
space between the fascia 300 (a first roof surface) and the outer
ends 304 of the roof rafters 302 (a second roof surface). As can be
understood from FIG. 3, insulation 306 is located between the roof
rafters 302 and the outer ends 308 of the insulation 306 and outer
ends 304 of the roof rafters 302 present a relatively uneven
surface across which the strip 100 may be installed. Across the
outer ends 304 of the roof rafters 302, the strip 100 compresses
and forms around the rafters 302. Across the outer ends 308 of the
insulation 306, the strip 100 may expand or remain the same size to
keep in contact with the insulation 306. Thus, continuous contact
is maintained between the strip 100 and both the rafters 302 and
insulation 306. This continuous contact is maintained without
dividing the strip 100 into separate segments that may engage
uneven surfaces presented in the space between the fascia 300 and
the roof rafters 302, if present.
[0022] In addition to being used in connection with a ridge cap or
a fascia, the strip 100 may be used in connection with other roof
portions or joints, examples of which are shown in FIG. 4. The
strip 100 may be deployed as a seal between or under the hip
shingles 402c applied where first and second roof surfaces 402a,
402b meet at the hip 402 of a roof 400 or as a seal between or
under ridge shingles 404c applied where first and second roof
surfaces 404a, 404b meet at the ridge 404 of a roof 400. In the
hip/ridge shingle installation shown in FIG. 4, the strip 100 may
form a tight seal between the respective roof surfaces 402a-c and
404a-c. The permeability of the strip 100 may allow air or other
gas to pass from the exterior of the house to and/or from the
interior of house between the roof surfaces 402a, 402b and 404a,
404b.
[0023] In various embodiments, the strip 100 may have a size in the
ranges of: three-quarters of an inch to an inch of nominal
thickness, three inches to 11.75 inches of width and a twenty foot
to fifty foot length. The strip 100 is configured to be torn or cut
to fit a particular application if needed (e.g. corners).
[0024] The physical properties (chemical composition) of the strip
100 allow the strip to compress or otherwise conform to the roof
panel, to irregularities on the uneven surface 108 or roof surface
204 or the uneven surfaces presented in the space between the
fascia 300 and the roof rafters 302. In one embodiment, the strip
100 is formed from a plurality of polyester and nylon fibers. In
one embodiment, the ratio of nylon to polyester fibers is 50/50. In
other embodiments, the strip 100 may be formed from polyethylene,
polypropylene, or other man-made or natural fibers. This chemical
composition, at least in part, enables the strip 100 to conform to
a specific roof profile or use by, for example, and as described in
more detail above, compressing around raised portions or rafters of
the roof and/or expanding or remaining the same size to keep in
contact with recessed portions or insulation of the roof. Unlike
polyurethane fibers used in prior art materials, the polyester
fibers of the present embodiment do not wick moisture into the
interior or other portions of the strip 100. Further, the polyester
fibers of the strip 100 may be coated in a rubber base material.
The rubber base material may provide fire proofing to the strip
100. In one embodiment, the strip 100 is manufactured as a single
baffled layer (without an external baffle layer) of non-woven
material with a binding agent. In one embodiment, the strip 100 is
manufactured with a binding agent called vycar x 58, which includes
polyvinyl chloride with aluminum tri hydrate. In these embodiments,
both the polyvinyl chloride and the aluminum tri hydrate may
function as fire retardants, thus providing fire proofing to the
strip 100. In one embodiment, the strip 100 is manufactured using
at least 90% recycled plastic material (30% post consumer content).
In one embodiment, the strip 100 has a net free area of 18 square
inches per linear foot of material. In one embodiment, the strip
100 has a net free area of 19.4 square inches per linear foot of
material.
[0025] Referring back to FIGS. 1A and 2A, the strip 100 may be
wound into a coil for packaging and delivery. In an installation
process, the strip 100 may be unwound from its coiled orientation
and progressively applied to a desired location on a roof surface
or other surface. In some embodiments, the strip 100 may be
attached to or otherwise secured to either of the respective roof
panel or surface by a fastener such as a nail, a screw or a clip.
In some embodiments, fasteners and/or adhesives, such as glue, may
be used to secure the strip 100 to the respective roof panel or
surface.
[0026] In some embodiments, and with reference to FIGS. 1A-2C and
4, the strip 100 may be installed under a ridge shingle of a roof.
In these embodiments, a venting slot may be cut along the apex of
the roof, e.g., at the apex of the roof panels. For example,
approximately a 1 inch slot may be created by cutting approximately
1/2 inch on each side of the ridge at the apex of the roof. The
venting slot may terminate prior to a rake edge of the roof. In
some embodiments, the venting slot may terminate approximately 12
inches from the rake edge. Once the venting slot has been created,
a ridge vent may be centered over the venting slot and the strip
100 may then be placed on the bottom of the ridge vent. In some
embodiments, the strip 100 may be placed approximately 1/2 inch
from a bottom edge of the ridge vent. The strip 100 may also be
placed on the end of the ridge vent at a terminal end of the
venting slot, e.g., where the ridge vent may meet the roof panel.
The strip 100 may be installed to the ridge vent either via
adhesive substance or fasteners (or both). After the strip 100 is
installed on the ridge vent, a ridge shingle (or other ridge cap)
may be placed over the ridge vent. For example, a ridge shingle may
be installed via two ring shank galvanized nails per ridge shingle.
The galvanized nails or other fasteners may then be inserted into
the ridge shingle such that there is approximately a 1/2 inch
between the ridge shingle and the roof panel (or other shingles
installed on the roof panel).
[0027] As appropriate, and with reference to FIGS. 1A-2C, the ridge
vent or cap may be secured to the roof surface (e.g., corrogated
sheet or roof surface of a composition roof) using an appropriate
tool. In one embodiment, a 3300 RPM screw gun may be used. The
strip 100 is adapted for easy installation. Specifically, a utility
knife or scissors may be used to cut the strip to ensure the strip
100 conforms to the desired length. The strip 100 may be caulked
without a connector or end plugs. Multiple strips 100 may be used
in combination to form a ventilation strip of any size. Adjacent
strips 100 may be "butt-fit" such that end portions of the strips
are in contact.
[0028] Referring back to FIG. 3, when installing the strip 100 in a
space between the fascia 300 and the ends 304 of the roof rafters
302, a slot (not shown) may be cut into a first roofing surface,
the fascia board 300 (or the roof deck, if appropriate). In some
embodiments, the slot may be approximately 1/2'' to 1'' and may be
configured to provide an air intake opening. The strip 100 (as
shown in FIG. 3) may then be applied within the slot, near the top
of the existing fascia board and approximately flush with the roof
deck. Once the strip 100 is positioned, fasteners (such as roofing
nails) may be inserted to secure the strip 100 to the fascia. In
one embodiment, the strip 100 may be secured approximately every
12'' along a center of the fascia 300. Once the strip 100 is
installed, a new fascia board (a minor roof panel), which
optionally may be capped with aluminum trip sheet, may be secured
on top of the strip 100 (e.g., via fasteners, adhesives or the
like). End caps, such as metal or wood, may then be installed to
cover the fascia board and the strip 100. A drip edge may be
included to cover the original fascia 300, the strip 100 and the
exterior fascia. In addition, a leak barrier or underlayment
shingles may also be included and may extend past the drip edge (if
included).
[0029] For methods of installing a fiber matting strip 100 in
accordance with the present disclosure, reference is now made to
the flow charts shown in FIGS. 5 and 6. FIG. 5 depicts a method 500
of installing the strip in connection with a ridge vent or under
hip/ridge shingles. Initially, at step 502, the strip 100 is
applied to a first roof surface. Next, in operation 504, the strip
100 may be optionally secured to the first roof surface. Next, in
operation 506, the strip is applied to a second roof surface. Then,
in operation 508, the strip 100 is secured to the second roof
surface (and the first roof surface if the strip was not secured to
the first surface previously). In connection with a ridge vent
installation, in operation 510, a ridge cap or vent is fastened to
the first roof surface and the second roof surface. In connection
with a hip/ridge shingle installation, in operation 512, hip or
ridge shingles (as applicable) are fastened to the first roof
surface and the second roof surface. Examples of this installation
configuration are shown in FIGS. 1B-1C, 2B-2C and 4.
[0030] FIG. 6 depicts a method 600 of installing the strip in
connection with a fascia. Initially, at step 602, the strip 100 is
applied to a first roof surface. Next, in operation 604, a minor
roof panel is fastened to at least the first roof surface. Examples
of this installation configuration are shown in FIG. 3.
[0031] By way of example and not limitation, the embodiments
illustrated herein include a minor roof panel having a smooth
surface and major roof panel having an uneven surface. It should be
appreciated that other roof configurations may be used in
connection with the strip 100. For example, the strip 100 may be
installed with a minor roof panel having an uneven surface and a
major roof panel having a smooth surface. In another example, the
strip may be installed in the space between the fascia and ends of
the roof rafters. In still another example, the strip may be
installed under the shingles that meet at the hip or ridge joint of
the roof.
[0032] The foregoing merely illustrates certain principles of
particular embodiments. Various modifications and alterations to
the described embodiments will be apparent to those skilled in the
art in view of the teachings herein. It will thus be appreciated
that those skilled in the art will be able to devise numerous
systems, arrangements and methods which, although not explicitly
shown or described herein, embody the principles of the invention
and are thus within the spirit and scope of the present invention.
From the above description and drawings, it will be understood by
those of ordinary skill in the art that the particular embodiments
shown and described are for purposes of illustration only and are
not intended to limit the scope of the present invention.
References to details of particular embodiments are not intended to
