Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit under 35 U.S.C. 119 (e)
of U.S. Provisional Application No. 60/571,969 filed on May 17,
2004, which is hereby incorporated by reference in its
entirety.
FIELD
[0002] This application relates generally to building products and
more specifically to a siding system.
BACKGROUND
[0003] Stucco sidings on homes provide an aesthetically pleasing
and weather resistant surface. More modern synthetic stucco systems
like Drivet and EFIS have largely replaced traditional stucco to
reduce material and labor costs. Modern synthetic stucco systems
have encountered severe product liability issues related to water
trapped in the wall cavity that cannot dry out before rot sets in.
What is needed is an alternative to stucco and synthetic stucco
systems that improves on the cost disadvantages of traditional
stucco and the trapped water disadvantages of synthetic stucco.
What is needed is a system that provides the exterior look of
stucco but is less expensive and allows water in the wall cavity to
escape before rot sets in.
SUMMARY
[0004] A building product includes a pultruded panel including a
first wall and a second wall separated by a space, the pultruded
panel configured to provide a stucco-like exterior surface when
mounted to a building.

DETAILED DESCRIPTION
[0009] In the following detailed description, reference is made to
the accompanying drawings which form a part hereof, and in which is
shown by way of illustration specific embodiments in which the
invention may be practiced. These embodiments are described in
sufficient detail to enable those skilled in the art to practice
the invention, and it is to be understood that the embodiments may
be combined or that other embodiments may be utilized and that
structural changes may be made without departing from the spirit
and scope of the present invention. The following detailed
description is, therefore, not to be taken in a limiting sense, and
the scope of the present invention is defined by the appended
claims and their equivalents.
[0010] FIG. 1 shows a profile, cross-section view of a panel 100,
in accordance with one embodiment. Panel 100 is used as part of a
siding system for a building. A plurality of panels 100 can be
vertically or horizontally mounted to a building and interlock with
one another. These panels 100 resist moisture and wind intrusion
into the building wall cavity. In some embodiments, panel 100
includes two panel walls 101 and 102 and a hollow space 140 between
the panel walls. In some examples there can be more than one hollow
space 140 in a panel. In some hollow panel embodiments, the panel
wall 102 facing the studs (and the building wall cavity) has
micro-perforations to allow for moisture to escape. In some hollow
panel embodiments, the panels 100 are mounted vertically to channel
intruding bulk water, such as rain, down the hollow space and away
from the building wall cavity. Vertically mounted panels are panels
in which the space 140 runs vertically up and down the
building.
[0011] Panel 100 mates with other panels at its ends. In this
example, one end of panel 100 includes a first finger 103 and a
second finger 104 that define a U-shaped mounting area 105
therebetween. The other end of the panel includes a curved finger
106 including a shoulder 107 and a cut-out area 108.
[0012] FIGS. 2 and 3 show a cross-section, top profile view, of an
assembled panel system according to one embodiment. A panel 110 is
equivalent to panel 100, as described above. In this example,
panels 100 and 110 are mounted vertically (such that space 140 runs
vertically up and down the building) and attached to building studs
120 with nails or screws 130. Cut-out area 108 provides a gap for
the head of the nail or screw. In other examples, panels 100 and
110 can be nailed over sheathing, instead of being mounted directly
to the studs. The two panels 100, 110 are connected at a seam 160.
The panels mate such that finger 106 is positioned between fingers
103 and 104 with shoulder 107 abutting the end of finger 103. In
mounting the panels, finger 106 of a first panel is inserted into
the gap 105 of a second panel and the first panel is then placed
flush against the structure and nailed or otherwise fastened
through its finger 104 to the structure.
[0013] As discussed, each panel can include one or more hollow
spaces 140 to channel bulk water away from the building wall
cavity. In some embodiments, the panel wall 102, facing the studs,
can include a plurality of small holes 163 such as
micro-perforations or micro-pores to allow for moisture vapor to
pass through the wall, allowing the building wall cavity to release
moisture.
[0014] In one embodiment, the panels 100 and 110 are constant
cross-section profiles formed by pultrusion. This is advantageous
because pultrusion can be produced with structural strength to
match or exceed traditional wood sheathing. This allows panels 100
to take the place of traditional sheathing and siding, thus greatly
simplifying the construction process. Also, pultruded products are
also less susceptible to mold and mildew growth than wood products.
Pultrusion also does not rot when exposed to moisture in the manner
that wood products can. Moreover, since the pultruded members have
a relatively high insulative property, they help the insulating
value of a structure wall.
[0015] Members 100 and 110 can be formed by pultrusion and can
include a coating or a film for additional protection from elements
or ultraviolet protection. For example, the pultrusion and coating
can be as described in commonly assigned U.S. Pat. No. 6,197,412,
which is incorporated herein by reference in its entirety. Panels
100 and 110 can be various lengths, for example, from a few inches
to 30 feet or longer. The members can also have various widths,
from a few inches to 4 feet or wider.
[0016] In some embodiments, panels 100 and 110 can be pultruded and
formed as composite parts. For example, glass, or other reinforcing
fibers, are impregnated with resin and pulled through a forming
guide and a heated die. The forming guide orients the fibers to be
properly placed in the heated die to insure that the pultruded part
has uniform reinforcement across its shape. The heated die cures
and/or solidifies the resin around the reinforcing fibers, thus
forming the composite part. The composite part, having a profile
shape, is continuously pulled out of the heated die by a puller.
The puller can be a clamp and stroke action from a reciprocating
puller, or a smooth action from a caterpillar puller.
[0017] Reinforcing fibers used in the example pultrusions can be
glass, carbon fiber, kevlar, and other organic and inorganic
filaments and fibers. Reinforcement fibers can take the form of
filament and strand bundles, called rovings. They also take the
form of yarns, texturized yarns, chopped strand mats, continuous
strand mats, knitted mats, woven mats, surfacing veils, and many
hybrid combinations of rovings, yarns, mats, and veils.
[0018] Resin used in example pultrusions can be thermosetting
resins like unsaturated polyesters in a styrene solution, or
polyurethanes, phenolics, epoxides, thermosetting blends, and other
thermosetting resins. Other resins used in pultrusion can be
thermoplastic resins based on polyurethanes, acrylics,
polyethylenes, and other thermoplastic resins. Resin used in
pultrusion can also be thermoplastic resins that are embedded in
rovings that melt and form the part inside the pultrusion die.
[0019] Resin mixtures in pultrusion can also contain organic,
polymeric, and inorganic additives for such properties as shrink
control, mold lubrication, colorants, fillers and other specially
additives.
[0020] In some embodiments, the interlock seam 160 can be covered
with sealant to match the color and texture of a weather-resistant
coating 170 on the pultruded panels 100 and 110. This embodiment
eliminates the appearance of the seam and produces a surface
appearance similar to stucco or synthetic stucco. For example,
coating 170 can be applied in-line during pultrusion at a low
gloss, and can include some texture that from a distance, looks
like synthetic stucco. In such an embodiment, there is no "stucco
material," . it just looks like there is. In another embodiment,
the panels 100, 110 can be painted or coated with a smooth or
textured finish. In general, the outer surface of panels 100, 110
has a stucco-like appearance having a generally flat, non-seamed
appearance.
[0021] Referring to FIG. 4, in another embodiment the panels 100,
110 can be covered with a thick, plaster-like coating 180 used on
synthetic stucco. In a further embodiment, these synthetic stucco
coatings can be shaped into decorative patterns. In a further
embodiment, the members can be covered in stucco, with and without
decorative patterns. In each of these embodiments involving stucco
or synthetic stucco coatings, the hollow panel wall still allows
for bulk water management and moisture movement, thus maintaining
the advantages over traditional stucco or synthetic stucco.
[0022] The above description is intended to be illustrative, and
not restrictive. Many other embodiments will be apparent to those
of skill in the art upon reviewing the above description. The scope
of the invention should, therefore, be determined with reference to
the appended claims, along with the full scope of equivalents to
which such claims are entitled.
