Description
RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional patent
Application Ser. No. 61/086,253, entitled "Fastener Blanket," filed
on Aug. 5, 2008, currently pending, which is incorporated by
reference herein in its entirety.
BACKGROUND
[0002] Fastener blankets disclosed herein relate to the field of
metal building construction, and more particularly to insulation
products utilized in metal building construction.
[0003] The current practices of providing insulation during
construction of metal buildings include the use of rolled batt
insulation, rigid board insulation, purlin blocks and/or insulated
metal panels. The desired insulation materials are typically
incorporated into the roof of a metal building, thought they can be
incorporated into the walls of the building as well.
[0004] Fasteners, such as screws, nails, bolts or the like, are
utilized to secure the building materials to the building
structure. Typically, the fasteners utilized to secure the
materials to the building structure pass completely through the
building materials, including any insulation materials, and extend
from the exterior of the building to the interior of the building.
These fasteners tend to be made of steel and are conductive. The
conductivity of the fasteners results in the fasteners acting as a
conduit for heat and cold to transfer through the building,
resulting in energy loss.
[0005] When batt insulation is used, the insulation is compressed
at the fastener locations when the metal roof and wall systems are
secured to the building's structure material. This compression
results in reduction of the insulating R-value properties of the
batt insulation. The compression of the batt insulation at the
fastener locations where the insulation is compressed can result in
the insulating R-value properties of the batt insulation being
reduced to practically zero. When rigid board insulation or
insulated metal panels are used to enclose and insulate a metal
building, they do not compress like batt insulation. However, the
fasteners that extend through the insulation materials still result
in energy loss.
BRIEF SUMMARY
[0006] Insulation products disclosed herein are fastener blankets
that can be utilized in the field of metal building construction.
The fastener blankets can be fitted over each row of the roof
and/or wall support members of a building. The fastener blankets
enclose the fasteners utilized to secure the building materials to
the building structure, thus reducing or preventing energy loss due
to heat or cold transferred through the fastener.
[0007] In one aspect, a fastener blanket to enclose a fastener
secured to building structural member is provided that includes a
top panel, a first side panel, and a second side panel. The
fastener blanket encloses a tip of a fastener attached to a
building structural member, and forms a closed shape with the
building structural member to which the fastener is attached.
[0008] In another aspect, a fastener blanket to enclose a fastener
secured to building structural member is provided that includes a
top panel, a first side panel, and a second side panel. The
building structural member is a purlin, and the fastener blanket
encloses a tip of a fastener attached to the purlin. The purlin has
a top portion, a vertical portion, and a bottom portion, and the
fastener blanket forms a closed shape with the purlin to which the
fastener is attached.
[0009] In a third aspect, a fastener blanket is provided that
includes a top panel, a first side panel including a first bottom
end that extends from the first side panel at an angle, and a
second side panel including a second bottom end that extends from
the second side panel at an angle. The fastener blanket encloses a
tip of a fastener attached to a purlin. The purlin has a top
portion, a vertical portion, and a bottom portion, and the fastener
blanket forms a closed shape with the purlin to which the fastener
is attached.

DETAILED DESCRIPTION.
[0015] Fastener blankets disclosed herein can be fitted over each
row of the roof and/or wall support members of a building to
enclose the fasteners utilized to secure additional building
materials to the building structure. The fastener blankets
disclosed herein can provide additional insulating R-value
properties at the points of the building where the current standard
practices provide avenues of significant energy loss. The fastener
blankets encompass the fasteners with an insulating material, which
can thus reducing energy loss of the building. The fastener
blankets can form a closed shape with the building structural
member to which the fastener is attached, and can enclose at least
part of the building structural member.
[0016] FIGS. 1-4 illustrate two embodiments of the present fastener
blankets in an exemplary installation on a purlin. A purlin is a
horizontal structural member utilized in constructing the roof of a
building. Purlins support the loads from the roof deck or
sheathing, and can be supported by the principal rafters, the
building walls, or both. In metal building roof systems, purlin
members generally have a "Z" shaped cross section, and arc
constructed from cold-formed steel. It should be understood that
the fastener blankets disclosed herein can also be utilized with
other structural members of a building. Preferably, the fastener
blankets disclosed herein can be installed by an installer prior to
installation of the roof and/or wall system for a building. Once
the fastener blanket is installed, the roof and/or wall systems can
be installed via standard building practices.
[0017] Fastener blankets can be made of any suitable material that
has appropriate insulating properties. The dimensions of the
fastener blankets, such as height, width and length, can be any
suitable dimensions for use in the intended application.
[0018] FIGS. 1 through 3 illustrate a first example of a fastener
blanket 100 installed on a purlin 102. Fastener blanket 100 has a
top panel 104, a first side panel 106 and a second side panel 108.
Purlin 102 has a top portion 110, a vertical portion 112 and a
bottom portion 114. Roofing materials, including insulation (not
shown), can be secured to the top portion 110 of the purlin
102.
[0019] When installed, fastener blanket 100 forms a closed shape
with the purlin 102, and encloses, or encompasses, at least part of
the purlin 102. The cross sectional shape of the closed shape of
fastener blanket 100 as installed can any suitable shape, and is
preferably a triangle. As illustrated in FIGS. 1 and 3, fastener
blanket 100 encloses the top portion 110 and at least part of the
length of vertical portion 112 of the purlin 102. For example, the
fastener blanket can enclose about half, less than about half or
more than about half of the length of the vertical portion 112 of
the purlin 102. As illustrated in FIGS. 1 and 3, the fastener
blanket encloses more than about half of the of the length of the
vertical portion 112 of the purlin 102.
[0020] Sections of insulating material, such as purlin block, can
be connected to fastener blanket 100. As illustrated first section
118a of insulating material is connected to the first side panel
106 and second section 118b of insulating material is connected to
the second side panel 108. The sections of insulating material can
provide added insulating properties. In examples where purlin
blocks are required, and are utilized as the sections of insulating
material connected to the fastener blanket, increased labor
efficiencies of the building's construction can also be
provided.
[0021] As illustrated in FIG. 2, the fastener blanket 100 can be
installed by flexing the top panel 104 to a flexed position in
which the first and second side panels 106 and 108 separate away
from each other. During installation, the fastener blanket 100 can
be placed in the flexed position, and can be placed over the top
portion 110 of the purlin 102. The fastener blanket 100 can then be
released so that the fastener blanket 100 achieves its closed
position. The fastener blanket 100 can be secured to the top
portion 110 of the purlin 102 by one or more fasteners 116, as
illustrated in FIGS. 1 and 3.
[0022] Once the fastener blanket 100 has been installed, roofing
materials can be secured to the top portion 110 of the purlin by
additional fasteners 116. As installed, head 120 of a fastener 116
is located above the top panel 104 of the fastener blanket 100 and
above top portion 110 of the purlin 102. Typically, the head 120 of
fastener 116 is located on the external side of the building, and
can be exposed to external weather conditions. The tip 122 of a
fastener 116 is located within the interior of the building, and is
below the top panel 104 of the fastener blanket 100 and the top
portion 110 of the purlin 102. As illustrated in FIG. 3, the tip
122 of a fastener 116 is enclosed by the fastener blanket 100. The
insulation provided by the fastener blanket reduces or prevents the
fastener 116 from transferring energy between the outside of the
building and the inside of the building.
[0023] FIG. 4 illustrates a second embodiment of a fastener blanket
200 installed on a purlin 202. Fastener blanket 200 has a top panel
204, a first side panel 206 having a first bottom end 208, and a
second side panel 210 having a second bottom end 212. Purlin 202
has a top portion 214, a vertical portion 216 and a bottom portion
218. Roofing materials, including insulation, can be secured to the
top portion 214 of the purlin 202. Fastener blanket 200 entirely
encompasses the purlin 202.
[0024] When installed, fastener blanket 200 forms a closed shape
that encompasses the purlin 202. The cross sectional shape of the
closed shape of fastener blanket 200 as installed can be any
suitable shape, and is preferably a trapezoid. The top panel 204 of
the fastener blanket 200 preferably has a width that is greater
than the combined width of the bottom ends 208 and 212. The first
and second side panels 206 and 210 of the fastener blanket 200
preferably have a length that extends beyond the bottom portion 218
of the purlin 202.
[0025] Bottom ends 208 and 212 of the fastener blanket 200
preferably extend towards each other from the first and second side
panels 206 and 210, respectively. The first bottom end 208 extends
from the first side panel 206 at an angle. As illustrated the angle
is greater than about 90.degree., although in other examples the
angle could be about 90.degree., or less than about 90.degree..
Similarly, the second bottom end 212 extends from the second side
panel 210 at an angle. As illustrated the angle is greater than
about 90.degree., although in other examples the angle could be
about 90.degree., or less than about 90.degree.. The first bottom
and 208 and the second bottom end 212 extend towards each other,
and contact each other at a point below the bottom portion 218 of
the purlin 202. First and second bottom ends 208 and 212 of the
fastener blanket 200 preferably bend upwards at the point where
they contact each other, and can contact bottom portion 218 of the
purlin 202.
[0026] Sections of insulating material, such as purlin block, can
be connected to fastener blanket 200. As illustrated first section
220a of insulating material is connected to the first side panel
206, and second section 220b of insulating material is connected to
the second side panel 210. First section 220a of insulating
material extends from the top panel 204 of the fastener blanket 200
to the first bottom end 208. Second section 220b of insulating
material also extends from the top panel 204 of the fastener
blanket 200 to the first bottom end 208. The sections of insulating
material can provide added insulating properties. In examples where
purlin blocks are required, and are utilized as the sections of
insulating material connected to the fastener blanket, increased
labor efficiencies of the building's construction can also be
provided.
[0027] Similarly to fastener blanket 100, fastener blanket 200 can
be installed by flexing the top panel 204 to a flexed position in
which the first and second side panels 206 and 210 separate away
from each other. During installation, the fastener blanket 200, in
the flexed position, can be placed over and around the purlin 202,
and can then be released so that the fastener blanket 200 achieves
its closed position. The fastener blanket 200 can be secured to the
top portion 214 of the purlin 202 by one or more fasteners 222.
[0028] Once the fastener blanket 200 has been installed, roofing
materials can be secured to the top portion 214 of the purlin 202
by additional fasteners 222. As installed, head 224 of a fastener
222 is located above the top panel 204 of the fastener blanket 200
and above top portion 214of the purlin 202. Typically, the head 224
of fastener 222 is located on the external side of the building,
and can be exposed to external weather conditions. The tip 226 of a
fastener 222 is located within the interior of the building, and is
below the top panel 204 of the fastener blanket 200 and the top
portion 214 of the purlin 202. As illustrated in FIG. 4, the tip
226 of a fastener 222 is enclosed by the fastener blanket 200. The
insulation provided by the fastener blanket 200 reduces or prevents
the fastener 222 from transferring energy between the outside of
the building and the inside of the building.
[0029] From the foregoing, it will be appreciated that although
specific examples have been described herein for purposes of
illustration, various modifications may be made without deviating
from the spirit or scope of this disclosure. It is therefore
intended that the foregoing detailed description be regarded as
illustrative rather than limiting, and that it be understood that
it is the following claims, including all equivalents, that are
intended to particularly point out and distinctly claim the claimed
subject matter.
