SIDING SYSTEM AND METHOD
Abstract
A siding system and method includes siding members, such as
siding panels that coupled together to form siding for a wall.
Other siding members can include both vertically and horizontally
applied siding such as beveled siding, lapped siding, sheeted
siding, siding paneling, exterior plywood, channel siding, board
and batt siding, non-panelized shingles and panelized shingles. In
implementations, the siding members are spaced from the wall by
vertically oriented furring members and/or horizontally oriented
vented furring members that can be affixed to the siding members
prior to affixing to a building structure. Some of the siding
panels have two-piece backer-board and shingle construction, or
one-piece backer-shingle construction, or one-piece backer-siding
construction. The siding panels are constructed to for various
joints between the panels when they are coupled together.

Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims priority benefit of provisional
application Ser. No. 60/715,437 filed Sep. 9, 2005.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention is directed generally to exterior
siding for buildings.
[0004] 2. Description of the Related Art
[0005] Cedar shingles have a long and rich history as siding
material in North America. Properly manufactured and installed,
traditional individual shingles perform very well. However, there
are shortcomings to traditional individual shingle systems.
Traditional individual shingles are very labor intensive and
expensive to apply. Those applying the shingles require a high
degree of skill to perform this job and these skills are in short
supply today. It is also very expensive and labor intensive to
apply finishes to individual shingles. Traditional individual
shingle systems do not allocate expensive raw materials efficiently
as they use considerably more expensive premium cedar in this
process. Individual shingles are also not well suited for energy
efficient home building methods that may require more effective
moisture management systems.
[0006] Manufacturers have tried, with limited success, to replicate
the performance and success of traditional individual shingle
systems using shingles preinstalled to a backing system or
backer-board at a manufacturing facility. The goals of these
systems are to reduce the consumption of expensive raw materials,
take advantage of less skilled, lower priced labor, capitalize on
the economies of factory assembly, and reduce the installation
costs in the field.
[0007] Historically, panel manufacturers (particularly those using
Western Red Cedar ("WRC") shingles) have focused on efforts to
reduce the amount of WRC used in these panels due to the high cost
of the raw material. Thus, while traditional shingle systems use
two-plies of shingles, many panel manufacturers today manufacture
their panels using one-ply of WRC shingles on a plywood sheathing
"backer-board" or WRC shingles on plywood sheathing backer-boards
with a felt overlay. Since shingles are also labor intensive to
apply, applying one-ply in lieu of two plies has also brought down
the labor costs. However, these designs have not fully compensated
for these and other shortcuts and as a result, shingle panel system
performance has suffered.
[0008] Shingle panel manufacturers using Eastern White Cedar
("EWC") do not have the same dilemmas regarding raw material costs
as do WRC manufacturers. As a result, they sometimes use a two-ply
shingle system. However, other aspects of their design have a
number of shortcomings, as will be discussed below.
[0009] Single Ply Panel Systems
[0010] One existing panelized shingle system utilizes plywood
sheathing (produced from wood species classified as non durable by
the USDA Forest Laboratory) as a backer-board. Strips of moisture
barrier (e.g., roofing felt) are then attached to the face of the
plywood backer-board to serve as a weather barrier in an attempt to
protect the plywood backer-board from the elements. A single layer
of shingles (typically WRC shingles) is then applied to the
backer-board resulting in a one-ply cedar shingle system on "felt."
Thus, this system replaced the traditional second layer of cedar
shingles (two-ply) with roofing felt in an effort to reduce
manufacturing and raw material costs. The sheathing grade used in
these panel systems is for siding underlayment that is not exposed
to the weather.
[0011] The system described above has numerous shortcomings. These
shortcomings include a system that is dependent on the performance
and longevity of the felt layer, which is not nearly as reliable as
a second layer of a durable wood species such as, for example,
Western Red Cedar, or of a non-durable wood that has been treated
to withstand the elements. The vulnerability of a system using a
felt layer increases in the keyways (the spacing between the
individual shingles) as the felt is directly exposed to the
elements including UV exposure, which can cause premature failure
of the felt. That failure exposes the backer-board, which is made
of non-durable materials, to be exposed to the elements.
[0012] It is also a problem if the exposed felt comes in contact
with certain finishes which can prematurely degrade the felt and/or
cause the felt to "bleed," thereby staining the shingles. Once the
felt has been breached, the weather can now access the plywood
sheathing which can cause premature decay and additional and
premature system failure including the backer-board to warp and/or
delaminate. In addition, the exposed felt visually detracts from
the aesthetics and architectural appeal of the panel.
[0013] In an effort to reduce the amount of exposed felt in the
keyways, at least one manufacturer makes two different styles in
their panels; one style without a keyway and the other with an
overly narrow keyway. Either approach ends up being a half-measure
as the cedar shingles expand and contract through climactic change
or from moisture variability in the shingles from the factory. The
shingles are susceptible to fracture, splitting, and cupping if
there is not sufficient amount of room in the keyway for them to
move.
[0014] Wood in service is exposed to both long-term (seasonal) and
short-term (daily) changes in relative humidity and temperature of
the surrounding air. Equilibrium Moisture Content is the moisture
content at which wood is neither gaining nor losing moisture (an
equilibrium condition). Because this condition is impossible to
maintain, the exposure to these changes causes swelling or
shrinkage of the wood, which results in movement of wood. To
provide for this swelling and shrinkage, the Cedar Shake and
Shingle Bureau, which serves as an industry leader in quality
assurance programs, recommends spacing shingles a minimum of 1/8''
to 1/4'' apart to allow for expansion and movement.
[0015] Shrinkage of shingles following application (usually due to
shingles containing more than the targeted moisture content when
produced at the factory or varying climate conditions in the field)
can increase the original keyway spacing, which in turn exposes
additional felt and increases the associated problems. Conversely,
water absorbed by dry shingles cause the shingles to swell
requiring space for them to move and expand. Without a sufficient
keyway space the shingles fracture and split damaging the integrity
of the panel.
[0016] Insufficient keyway space also increases cupping from
pressure exerted on the shingles as they expand and eventually come
together. The cupping of the shingles occurs across the width of
the shingle becoming more severe at the edges of the individual
shingles. The pressures exerted from expansion and contraction is
often severe enough to at least partially dislodge the shingles
from the backer-board, which can cause premature panel system
failure and compromises the aesthetics of structure.
[0017] Panel systems such as those described above may also utilize
a back-stapling system to hold the shingles in place until the glue
line that eventually secures the shingles to the plywood, cures.
These staples are often electro-galvanized staples which will
ultimately cause iron-bleed in the event that they (a) protrude
though the face of the shingle when manufactured (are over driven),
(b) hit a void in the plywood, which causes the staple to over
drive, or (c) become exposed at a later date through weathering and
wear of the shingle face.
[0018] Another existing panelized shingle system utilizes plywood
sheathing (produced from wood species classified as non durable by
the USDA Forest Laboratory) as its backer-board and a single layer
of shingles (typically WRC shingles) applied directly to the
plywood backer-board. This results in a one-ply cedar shingle
system on plywood sheathing. This system does away with the
traditional second layer of cedar shingles (the two-ply system) in
an effort to reduce manufacturing and raw material costs. The
sheathing grade plywood used in this panel system is for siding
underlayment that is not exposed to the weather. This system also
has numerous shortcomings.
[0019] One manufacturer, recognizing the problems associated with
using roofing felt as a layer between the backer-board and the
shingles as in the panel shingle system discussed above, developed
a different system that creates problems of its own. In this
system, the felt is eliminated by applying the shingles to the
plywood backer-board without any space or keyway between the
shingles. This, in effect, gives an exterior surface of "solid"
cedar in an effort to protect the plywood sheathing backer-board
from the elements.
[0020] In this system, the manufacturer uses PVA glue, which has
little or no elasticity, to glue the shingles to the backer-board.
This glue is applied to the entire back of the shingle in an
attempt to restrict any movement of the shingles in an effort to
protect the plywood backer-board from the elements. The combination
of the shingles being held tightly together without a keyway and
the full cover glue system creates significant problems due to the
need of the shingles to expand and contract with climactic changes.
When the shingles are restricted in this manner, the pressures that
develop can fracture, split, or cup the shingles and also can cause
the backer-board to become exposed, which again may result in
premature panel failure.
[0021] Multiple Course Panel Systems
[0022] Multi-course panel designs are available, but these systems
have numerous disadvantages. First, they produce more waste during
installation than a single course design. Second, the panels
require more labor to manufacture and to install. Third, the panels
are heavier and more difficult to install. Fourth, some of these
systems do not adequately provide for an unexposed fastening method
when fastening the panel to the wall. The fasteners applied to the
top horizontal edge of the panel are generally concealed (other
than those fasteners that end up in the key ways) by the overhang
of the succeeding panel. However, nailing regimens throughout the
balance of the panel (the majority of the fasteners) fasten the
panel to the wall system via face nailing, which leaves the heads
of the nails exposed. This detracts from the visual and
architectural appeal of the shingle panel from the outset and
creates increased problems over time with the eventual rust of the
fastener and subsequent stain that develops on the shingles as a
result of this procedure. Exposed fasteners also subject the
fastener to the elements and can cause premature fastener failure
resulting in unsecured panels on the wall. Exposed fasteners also
create problems in the finishing process. Stains, paints, bleaching
oils, and other finishes produced and recommended for wood are
often not formulated to adhere properly to the metal fasteners,
and/or finish differently (often creating "shiners") when applied
to exposed fasteners.
[0023] At least one manufacturer uses a "blind nailing system" in
connection with a multi-course panel. This system requires that the
fasteners be driven in at an upwards angle underneath the bottom of
various individual shingles. The object is to drive the head of the
fastener up underneath the bottom edge of the shingle. This system
has severe shortcomings because the nail coatings are often damaged
in the process (which can cause premature fastener failure) and
because many of the nail heads remain at the worst possible
location, which is at or near the drip line of the shingle they are
attempting to conceal the fastener under.
[0024] Another manufacturer of multi-course panel design applies
fasteners to the top horizontal edge of the panel that are
generally concealed (other than those fasteners that end up in the
keyways) by the overhang of the next higher and succeeding panel.
However, nailing regimens throughout the balance of the panel
(i.e., the majority of the fasteners) fasten the panel to the wall
system via face nailing. This detracts from the visual and
architectural appeal of the shingle panel from the outset and
creates increased problems over time with the eventual rust of the
fastener and subsequent stain that develops on the shingles as a
result of this procedure. In addition, exposed fasteners are
subjected to the elements and can cause premature fastener failure
resulting in unsecured panels on the wall. Exposed fasteners also
create problems in the finishing process because stains, paints,
bleaching oils, and other finishes produced and recommended for
wood are often not formulated to adhere properly to the metal
fasteners, and/or finish differently (often creating "shiners")
when applied to exposed fasteners.
[0025] A third manufacturer of multiple ply panel systems uses
plywood sheathing (produced from wood species classified as non
durable by the USDA Forest Laboratory) with a layer of perforated
asphalt felt covering the sheathing. A layer of a product sold
under the trade name "Home-Slicker" is then applied over the
perforated asphalt felt. A double course of shingles (typically
EWC) is then applied over this backer-board system. A panel
constructed in this manner consumes more raw materials and
subsequently more labor is necessary to apply these materials to
their panel relative to other panel systems described above. This
panel is also significantly heavier and more cumbersome and
difficult to apply than other panel systems.
[0026] The application of the Home-Slicker product between the
shingles and the backer-board in this system is problematic. The
manufacturer of Home-Slicker states that wind-driven rain from the
outside and moisture vapor from the home's interior often remain
trapped between the siding and the house wrap. The Home-Slicker
manufacturer advises that their product be placed between the
sheathing of the house and the siding material. Although
Home-Slicker may play some role in the panel system described
above, it does not address the real problem: moisture management
between the house sheathing and the siding system where moisture
related problems normally arise.
[0027] Problems Associated with Existing Systems Described
Above
[0028] The existing systems described above use backer-boards that
are produced from plywood sheathing making it difficult if not
impossible to manufacture a backer-board profile that provides an
interlocking style horizontal joint. The resulting horizontal
backer-board joint consists merely of the plywood being roughly
beveled to allow each succeeding panel to "slip" past the prior
panel in an attempt to close this joint, thereby creating a
horizontal void behind the panels when applied. This void creates
horizontal channels for water and vapor to migrate throughout the
wall system. The void created is tapered (vertically) and as such
the panel does not readily accommodate a moisture
management/furring strip system.
[0029] These systems may include horizontal backer-board joints
that consist merely of the plywood being cut square to allow each
succeeding panel to "butt up" to the preceding panel producing an
open joint. The system described above that eliminates the keyway
between the shingles on the backer-board does not provide for an
overlapping joint. However, since this system is prone to failure
due to expansion and contraction of the shingles, the backer-board
and the open joint between the panels can become exposed to the
elements, which can introduce moisture into the wall system.
Negative pressure build up in the wall system can exacerbate this
problem by sucking moisture into the wall system through this open
joint. The void behind the panels creates horizontal channels for
water and vapor to migrate throughout the wall system. The void is
tapered (vertically) and as such the panel does not readily
accommodate a moisture management/furring strip system. Indeed, the
systems described above block vertical migration of moisture
because the top horizontal edges of the panel are fastened tightly
to the wall.

DETAILED DESCRIPTION OF THE INVENTION
[0050] As discussed above, pre-manufactured panelized shingle
systems offer the benefits over the direct application of shingles
as siding by reducing the use of raw materials and minimizing labor
costs. As discussed above, however, current panelized shingle
systems have a number of drawbacks. A siding system and method is
discussed below to address one or more of the drawbacks found in
existing panelized systems. Various aspects of the siding system
can be used in conjunction with conventional siding products or
systems such as use of the vented furring strip as further
discussed below. Other aspects of the siding system can be used to
replace use of conventional siding products or systems as further
discussed below.
[0051] The siding system includes a siding member. Exemplary
implementations of the siding member depicted below include a
siding panel such as a dual piece backer-board and shingle
combination, a single piece backer-siding board, and a single piece
backer-shingle board. These implementations of the siding member
show various uses of vertical furring strips (members) and vented
horizontal furring strips (members). These implementations are used
as examples and are not intended to limit the use of the vertical
furring strips and the vented horizontal furring strips. For
instance, other implementations of the siding member used with the
vertical furring strips and the vented horizontal furring strips
can include, but are not limited to, both vertically and
horizontally applied siding such as beveled siding, lapped siding,
sheeted siding, siding paneling, exterior plywood, channel siding,
board and batt siding, non-panelized shingles, and panelized
shingles. The siding member can be made from materials such as
fiber cement, vinyl, aluminum, wood, brick, stone, etc.
[0052] As further discussed below, the vertical furring strips and
the vented horizontal furring strips can be affixed to the siding
member as an assembly such as during manufacture at a factory prior
to affixing the siding member and vertical furring strips and
vented horizontal furring strips to a building structure.

[0138] As discussed above, plywood has historically been the
backer-board of choice by panel manufacturers due to its relative
low cost. More recently, rising costs of plywood have made a solid
wood backer-board more attractive and an economically viable
alternative. Today, a solid wood backer-board may be the lowest
cost option for the manufacturer. At the least, a solid wood
backer-board is currently cost effective.
[0139] An implementation of the present system uses a solid wood
backer-board (natural or finger-jointed) in lieu of a plywood
sheathing backer-board as used in existing panel systems. A solid
wood backer-board eliminates any possibility for the backer-board
to delaminate if the backer-board is subjected to moisture and
other elements. Use of a durable wood, such as WRC, or a nondurable
wood that has been specifically treated to withstand the elements
in lieu of plywood eliminates many of the problems associated with
existing systems.
[0140] Plywood sheathing backer-boards typically contain more
moisture (from the plywood manufacturer) than the targeted moisture
content of the shingles that are applied to them. Excessive
moisture in plywood backer-boards can cause excessive shrinkage of
the backer-board after application in the field, creating voids and
gaps in the siding system.
[0141] An implementation of the present system uses shingles and
backer-boards manufactured from WRC, which is a naturally durable
wood species (as classified by the USDA Forest Laboratory), highly
weather resistant and commonly used in exterior siding
applications. An implementation of the present system uses a
backer-board and shingles that are kiln dried to a similar moisture
content eliminating excessive moisture variability in the finished
product.
[0142] An implementation of the present system uses a "true"
two-ply "Cedar on Cedar" design providing the optimum in weather
protection, durability, and appearance. The two-ply "Cedar on
Cedar" design results in a panel with the rigidity necessary to
cover horizontal wall spans without undesirable deflection, while
still having the flexibility to be used in architectural features
requiring curvature of the panel.
[0143] While the implementation described above uses Cedar on
Cedar, other naturally durable woods may be used. Non-durable woods
appropriately treated can also be used.
[0144] In prior panelized system designs, durable wood shingles
(e.g., cedar) were placed on plywood made of non-durable wood
either with or without a layer of roofing felt in between. A
drawback to the design without the roofing felt was durability
because the elements could degrade the plywood. Another drawback to
the design using the layer of roofing felt was the unattractive
appearance of the roofing felt between the shingles. By using a
durable wood backer-board (whether a solid backer-board or a
backer-board using a laminate having a durable wood outer layer),
both of these problems can be alleviated. The former problem is
alleviated because durable wood is used in both the shingle and
backer-boards. The latter problem is solved by the use of a durable
wood face for the backer-board together with durable wood shingles,
which together give the appearance and the functionality of
two-plies of shingles when only one ply of shingles is applied.
[0145] The implementation of the present system using the solid
wood backer-board has additional benefits, including environmental
benefits. Systems using backer-boards made of plywood sheathing
contain large amounts of non-renewable petroleum based adhesives
containing formaldehyde and other undesirable compounds that may
create health and environmental concerns. By incorporating a solid,
durable, all natural Western Red Cedar backer-board containing
no/low VOC's (Volatile Organic Compounds), one implementation of
the present system alleviates these health and environmental
concerns.
[0146] An implementation of the present system using a solid
durable wood backer-board also allows the use of a backer-board
profile that serves numerous purposes. This profile makes it
possible to install a moisture management system to the panel at
the factory. The profiled backer-board also allows the panels to be
installed flush with the wall system when applied; eliminating the
horizontal voids that occur in panels previously used and other
siding systems. The backer-board of an implementation of the
present system provides the appropriate profile for the architect
and/or builder to conveniently design and construct appropriate
moisture management systems that they deem appropriate for their
particular application and environment.
[0147] The profile of the implementation using the solid wood
backer-board is illustrated in FIG. 1 and FIG. 2. The backer-board
used in this implementation is tapered with the thicker end being
the bottom of the backer-board and the thinner end being the top of
the backer-board. The top of the backer-board is notched, while a
lip extends downward from the bottom of the backer-board. When
installed on a wall, the bottom lip of one backer-board fits over
the top of the next lower backer-board and fits in the notch of the
lower backer-board. The mating lip and notch form a joint that
creates a barrier to prevent the underlying wall from being exposed
to the elements. The shingles that are applied to the backer-board
extend below the bottom of the lip, thereby providing greater
protection from the elements.
[0148] The implementation of the present system using a solid wood
backer-board provides a seamless underlayment for the individual
shingles that are applied to it. As shown in FIGS. 1-3, shingles
are glued to the face of the backer-board. The bottom of the
shingles extends typically an inch and a half below the bottom of
the backer-board so that when installed the shingles of an upper
panel overlap the top of the panel immediately below. Because the
backer-board is a durable wood, it is possible to leave full, open
keyways between the shingles, which make up the top layer of the
system. As a result, this present panel system has full keyways,
and the space behind the keyway is covered by a durable wood (or
treated non-durable wood), such as WRC. Providing a full keyway
allows the shingles to expand and contract naturally with the
environment.
[0149] This embodiment of the present system also eliminates the
necessity to off set keyways on succeeding layers of shingle
panels. The durable wood backer-board is a continuous unit. The
durable wood of the backer-board effectively simulates a "shingle"
that is 32 inches to 8 feet wide (the length of the panel assembly)
with no key-ways that require covering or off-setting from the
succeeding layer (of shingles). See FIGS. 4-5, and 10. This feature
simplifies application in the field.
[0150] A second implementation of the siding system 100 is shown in
FIG. 8 to include a backer-shingle board 190 that has an interior
portion that serves as a backer-board integral with an exterior
portion that serves as a shingle incorporated into a one piece
construction. A third implementation of the siding system 100 is
shown in FIG. 9 to include a backer-siding board 230 that serves as
both a backer-board and siding incorporated into one piece. The
backer-siding board can be made of various materials used in the
conventional siding industry as well as the particular materials
discussed herein.
[0151] The implementation of the present system described below may
be used with a starter strip that can be installed at the factory
or in the field in conjunction with the first or bottom panel. See
FIG. 3. A notch cut in the top of the starter strip accommodates
the lip of the bottom of the backer-board. This starter strip
extends the backer-board so that it becomes flush with the butt
line of the shingles eliminating the voids created by the keyways
in the first course. This starter strip has vertical grooves on the
backside to allow moisture to escape through the bottom of the
vertical vent. The Starter Strip is constructed from either a
durable wood (e.g., WRC) or an appropriately treated nondurable
wood.
[0152] The solid backer-board used in an implementation of the
system eliminates the need for double coursing (as found in
traditional shingle systems) on the first row of shingles. The WRC
backer-board or durable wood backer-board and starter strip serve
as the second course. See, e.g., FIGS. 3-6.
[0153] One implementation of the present system provides vertical
furring strips that are applied to the back of the siding member
including versions of the siding panel such as having the
backer-board, the backer-shingle board, and the backer-siding
board. These furring strips are illustrated best in FIGS. 1-2, 8-9,
and 11-15. In this implementation, the top of the furring strip is
applied approximately 1 inch below the top of the backer-board. The
bottom of the furring strip extends roughly 1 inch below the bottom
of the backer-board. When installed, the bottom of the furring
strip of an upper panel fits behind the backer-board of the lower
preceding panel. The lip of the upper panel fits in front of the
notch of the lower panel, thereby creating a weather-resistant
joint. The furring strip together with the profile of the
backer-board allows easy installation of successive panels. This
feature of the present system provides several benefits.
[0154] First, a panel of the present system is easy to handle and
requires only one person for fast, simple and straightforward
installation. The panel requires less skill in the field to apply,
as much of the assembly that requires highly skilled labor has been
performed at the factory. This system may reduce application time
in the field by up to 86% compared to the application of
traditional shingles; and is far simpler than multi-course panel
systems.
[0155] Second, the present system also produces significantly less
waste during the application process. Multi-course panel systems
produce significant waste, especially when trimming around doors,
windows, gables, dormers and other features. Traditional individual
shingles also produce significant waste and require extensive time
consuming trimming during the application process.
[0156] Third, the present system reduces the chance of water
leakage. The USDA Forest Products Laboratory has identified water
leakage as the number one culprit in moisture related problems. The
profiled backer-board includes an overlapping horizontal joint
providing easy alignment and added protection against outside
moisture migrating to the interior of the wall system. Prior
systems use non-durable plywood sheathing that is difficult if not
impossible to mill into the profiles necessary to create horizontal
overlapping joints necessary for higher levels of moisture
protection in shingle panel systems.
[0157] The implementation of the present system described below
allows the panels to be mounted flush to the walls without creating
any horizontal voids along the length of the wall. In addition,
this implementation provides a vertical space that allows moisture
to escape. In contrast, prior systems using plywood sheathing made
from non-durable wood as backer-boards created a tapered horizontal
void along the overlapping seam of each panel, thereby allowing
horizontal moisture migration along the wall. In the prior systems,
the top of the panel fits flush to the wall sheathing effectively
blocking vertical moisture migration. An ideal moisture management
system does just the opposite by restricting or prohibiting
horizontal migration of moisture and by providing for vertical
moisture migration so moisture can escape.
[0158] Existing systems using plywood backer-boards also do not
readily accommodate vertical furring strips because the shingle
panels do not lay flush against the wall structure where the panels
join together at the horizontal joints. Wood kept constantly dry
does not decay. Moisture and temperature are the principal factors
that affect the rate of decay in wood. Thus, because the existing
systems create horizontal voids that can collect water and because
the prior systems do not provide for any vertical venting, their
use may result in decay and failure of the panel system and
underlying wall.
[0159] The vertical furring strips in the present system address
and manage a number of issues including; capillary migration of
moisture, water driven in from the outside, moisture vapor from the
homes interior, wall temperature, interior wall pressure, and
airflow between the panel and the house sheathing (normally clad
with some form of "building" paper). Furring out exterior siding
helps paints, finishes and siding materials achieve their maximum
life span, provide a means for infiltrated water to escape and
allows the interior of the wall system to dry rapidly before it can
be damaged by moisture. Traditionally, high costs, shortage of
skilled labor, tedious and time consuming factors and the lack of
compatibility with the siding material has limited the use of
necessary furring systems in sidewall construction.
[0160] The backer-board of one embodiment of the present system
allows factory installed moisture management features to be
incorporated into the panel. The vertical furring strips applied to
the back of the backer-board create an airspace between the wall
and the backer-board, as detailed in FIG. 3. This is done in lieu
of installing the moisture management/furring system directly to
the wall structure (in the field) as in existing systems.
[0161] Having the furring strips oriented vertically on the
backer-board allows water vapor to migrate upwards through the vent
system and escape; and it allows condensed water to migrate
downward through the bottom of the vent system and escape. See FIG.
3. This is in contrast to prior systems in which the furring strips
were horizontal, which trapped water vapor and condensed vapor
between the furring strips impeding the escape of this moisture,
thereby causing damage to the wall system. In one implementation of
the present system, the furring strips are a solid wood product and
do not compress under pressure from the fasteners when the panel is
applied to the wall system. This ensures that the integrity of the
air cavity between the panel and wall system is not
compromised.
[0162] This feature of one implementation of the present system
provides an effective means to vent and drain trapped moisture,
provide a thermal break, accommodate air flow and regulate pressure
within the wall system. In addition, vertically applied furring
strips retard the horizontal migration of bulk water as a result of
catastrophic event such as a plumbing failure between the siding
and sheathing, breach in the exterior siding, or a similar event.
Modeling also shows that this furring system will retard horizontal
flame spread between the siding and sheathing, as horizontal flame
migration would have to burn through succeeding furring strips on
16'' intervals. This feature also provides an insulation layer that
makes the resulting wall more energy efficient.
[0163] Use of the vertical furring strip in conjunction with the
profiled backer-board also provides for easier, quicker, and
cheaper installation of panels to the wall. The lower portion of
the furring strip, which extends below the bottom of the panel, is
secured behind the fastened top edge of the preceding panel. See
FIGS. 1 and 2. The top of the panel is then fastened to the wall.
The succeeding panel covers the fasteners securing the preceding
lower panel, providing a blind nail system that provides a more
secure attachment to the wall to resist extreme weather, such as
high winds. See FIGS. 1-4, and 16.
[0164] A significant percentage of panelized shingles are
pre-finished prior to installation in the field. In the event that
the panels require face nailing during application, a top coat of
finish will need to be applied in the field to cover the exposed
fasteners, often referred to as "shiners." This is an added
expense, time consuming and weather dependent.
[0165] The present system eliminates "face nailing" in that it can
be applied as easily and in a similar manner as common lap siding.
Each panel is nailed to the wall along the upper edge of the panel,
and the nails are in turn hidden by the succeeding overlapping
panel. In one implementation of the present system, dimples are
applied at the factory to assist the installer of the panel to
locate the proper fastener location. The dimples are applied on the
face of the panel (16'' O.C.) approximately 7/8'' from the top of
the panel. See FIG. 14. By utilizing this nailing regimen, the
panel is secured to the wall system through the thickets cross
section of the panel (through the panel and furring strip),
providing the most secure application method available. This
nailing regimen also eliminates panel deflection caused by
over-driving fasteners in areas between the furring strips.
[0166] Another implementation of the present system uses a
horizontal vented furring strip (member) that can be applied
horizontally, either at the factory or in the field, to the
backside of the backer-board in between the furring strips. See
FIG. 7. The vented furring strip incorporates a number of groves
that allow water vapor to escape while providing a vertical fire
break. This fire break can retard vertical flame spread between the
siding and sheathing. The horizontal vented furring strip can be
used on a shingle panel that is applied at or near the top of the
wall system for each level of the structure.
[0167] As discussed above, shingles made of wood expand and
contract when their moisture content increases or decreases. Thus,
an implementation of the present system can use a two-part adhesive
system with more elasticity to secure the shingles to the
backer-board. Using an adhesive with greater elastic qualities as
the primary bonding agent allows secure attachment of the shingles
to the backer-board when the shingles expand and contract in
response to climatic change. Since this adhesive requires time to
cure, it is desirable to use a different type of adhesive (which
acts as a chemical staple) to hold the shingles and backer-board
together securely until the primary bonding agent cures. This
eliminates potential fastener exposure and stain/bleeding issues
that can occur from "back stapling". This two-part system holds the
shingles firmly to the backer-board while providing the flexibility
necessary for the shingles to expand and contract naturally with
the environment. The adhesives that can be used are common. For
example, a poly-urethane mastic construction adhesive may be used
as the primary bonding agent (i.e., the long-term bonding agent),
while a quick-curing hot melt adhesive can be used as the interim
bonding agent while the primary bonding agent cures.
[0168] A number of corner options have been developed for use with
the present system. As illustrated in FIGS. 17-20, a prefabricated
solid wood piece with a milled relief can be used as an inside
corner. The milled relief helps to accommodate irregularities (a
common problem) where the inside corners of the panel and/or wall
meet. This profile enables the inside corner to be installed with
ease and to fit flush with the converging angles of the inside
corner, providing a good fit and match for siding
installations.
[0169] A solid wood outside corner trim features a profile
utilizing an interlocking joint that gives the outside corner a
secure weather resistant fit along with enhanced architectural
appeal. See FIGS. 17-20. This prefabricated corner may be
pre-assembled at the factory or assembled with ease in the
field.
[0170] The current system can also be used with a prefabricated
flush shingle corner system as shown in FIG. 17. In the denoted
"Flush Shingle Corner Trim"), the shingles on the corners are flush
with the shingles on the panel system. This corner trim uses a
durable wood backer-board (in lieu of a plywood sheathing
backer-board as in prior systems).
[0171] While the system and its various components can be made from
any durable wood and non-durable wood that has been treated to
resist the elements, kiln dried Western Red Cedar represents a
typical material from which to construct the backer-boards. Kiln
Dried Vertical Grain, Clear, Heartwood Western Red Cedar is
typically used to construct the shingles in the present system.
[0172] An exemplary implementation is described below to aid in
illustration, but is not intended to limit the scope of the present
system and method in any manner. The exemplary implementation is an
advanced two-ply "Cedar on Cedar" shingle panel design; superior to
traditional individual shingle systems, panel systems utilizing
plywood backer-boards and multi-course panel systems. The exemplary
implementation features a solid, durable, genuine natural wood
Western Red Cedar backer-board in lieu of a plywood sheathing
backer-board. This eliminates the possibility of plywood
delamination of the backer-board in the event the backer-board is
subjected to interior or exterior moisture. The exemplary
implementation incorporates a two-ply "Cedar on Cedar" design
providing enhancement in weather protection and durability by using
Western Red Cedar Shingles on a solid, durable, Western Red Cedar
backer-board.
[0173] The exemplary implementation features a two-part adhesive
system to secure the shingles to the backer-board. This two-part
system holds the shingles firmly to the backer-board while
providing the flexibility necessary for the shingles to expand and
contract naturally with the environment. The exemplary
implementation includes full natural key-ways allowing the shingles
to expand and contract naturally with the environment.
[0174] The backer-board of the exemplary implementation includes a
profile that makes it possible to install the associated moisture
management systems directly to the system at the factory. The
backer-board also allows the panels to be installed flush with the
wall system when applied; eliminating the horizontal voids that
occur in other shingle panel and siding systems.
[0175] The exemplary implementation's unique profiled backer-board
includes an advanced milled overlapping horizontal joint that
provides easy alignment and added protection against moisture from
the outside migrating to the interior of the wall system. The
exemplary implementation's backer-board with the horizontal joint
creates a substantially full coverage overlapping backer-board.
[0176] The exemplary implementation features secure overlapping
vertical end joints providing for seamless application and for
further protection from the elements.
[0177] The exemplary implementation's unique profiled backer-board
is designed to include factory installed vertical furring strips
applied directly to the back-side of the backer-board. The
exemplary implementation's vertical furring strips are applied
vertically to vent and drain trapped moisture, provide a thermal
break, accommodate air flow and regulate pressure within the wall
system.
[0178] The exemplary implementation's factory installed furring
strips include a "snap lock" feature providing additional
application security. The lower portion of the furring strip, which
extends below the bottom of the panel, is secured behind the
fastened top edge of the preceding panel. This feature provides an
added level of security in environments with extreme weather
conditions. The exemplary implementation's "snap lock" feature is
the ultimate solution for a total "blind nail" system.
[0179] The exemplary implementation's siding panel is specifically
designed to eliminate the need for "face nailing." The siding panel
is fastened along the upper edge of the panel and the fasteners are
hidden by the succeeding overlapping panel.
[0180] The exemplary implementation's "nailing guide" has been
developed to locate the proper fastener location for the
applicator. This guide consists of a factory applied "dimple" on
the face of the panel (16'' O.C.) approximately 7/8'' from the top
of the panel. By utilizing this fastening regimen, the panel is
secured to the wall system through the thickets cross section of
the panel (through the panel and furring strip), providing the most
secure application method available. This fastening regimen also
eliminates panel deflection caused by over-driving fasteners in
areas between the furring strips. The design of the exemplary
implementation's "nailing guide" is also unaffected by
pre-finishing activities that could mask other various nail guide
systems.
[0181] The siding panel features a two-part adhesive system to
secure the shingles to the backer-board; eliminating the need to
back staple with electro-galvanized staples. This eliminates
potential fastener exposure and stain/bleeding issues that can
occur from back stapling methods.
[0182] The exemplary implementation can use Vertical Grain, Clear
and Heartwood Western Red Cedar shingles in the panel system.
Scientific studies and practicable experience show that these
shingles move less, cup less and retain finishes better than flat
grain shingles.
[0183] The exemplary implementation can include Western Red Cedar
shingles to industry standards featuring a full butt thickness for
added longevity. These shingles are up to 20% thicker than "scant"
shingles found on other panel systems. The exemplary implementation
can include rebutted and rejointed (R&Rs) shingles to provide
clean, crisp, distinctive shadow lines for optimum architectural
appeal.
[0184] The exemplary implementation can include vertical grain
shingles have a textured band sawn "A" face, which absorb stains,
paints and other finishes more readily and evenly compared to other
milled surfaces.
[0185] The exemplary implementation can be designed to work
efficiently with factory finishing operations, providing added
value. The exemplary implementation can include the single course
panel design to fit substantially all standard pre-stain equipment
used by pre-stain facilities today.
[0186] The exemplary implementation is easy to handle and requires
only one person for fast, simple and straightforward installation.
The exemplary implementation can require less skill in the field to
apply; as much of the assembly that requires highly skilled labor
has been performed at the factory. This also can make the exemplary
implementation a great choice for DIY installers. The exemplary
implementation can reduce application time in the field by up to
86%; compared to the application of traditional shingles and is far
simpler than cumbersome multi-course panel systems.
[0187] The exemplary implementation produces significantly less
waste during the application process. Multi-course panel systems
produce significant waste, especially when trimming around doors,
windows, gables, dormers and other features. Traditional individual
shingles also produce significant waste and require extensive time
consuming trimming during the application process.
[0188] The exemplary implementation can include an environmental
and family friendly backer-board system. The exemplary
implementation can feature a solid durable Western Red Cedar
backer-board containing no/low VOCs (Volatile Organic Compounds).
(Plywood backer-boards contain large amounts of adhesives
containing formaldehyde and other undesirable compounds that create
health and environmental concerns).
[0189] The exemplary implementation can include a prefabricated
solid wood inside corner trim has been designed with a milled
relief in order to accommodate irregularities where the inside
corners meet. This profile enables the inside corner to be
installed with ease and to fit flush with the converging angles of
the inside corner.
[0190] The exemplary implementation solid wood outside corner trim
features a unique profile and interlocking joint that gives the
outside corner a secure weather resistant fit along with enhanced
architectural appeal. This prefabricated corner was designed so
that it may be pre-assembled at the factory or assembled with ease
in the field.
[0191] The exemplary implementation can be designed with a
prefabricated flush shingle corner system. The exemplary
implementation can utilize the unique profiled solid real wood
backer-board (in lieu of a plywood sheathing backer-board for their
flush shingle corner system.
[0192] The starter strip of the exemplary implementation has been
designed to be used with the first panel on the wall system. This
starter strip was developed to extend the backer-board so it
becomes flush with the butt line of the shingles eliminating the
voids created by the key-ways in the first course. This starter
strip has also been grooved on the backside to allow moisture to
escape through the bottom of the wall system. The exemplary
implementation's unique backer-board design with the starter strip
eliminates the need for double coursing on the first row of
shingles. The exemplary implementation's WRC backer-board and
starter strip serve as the second course.
[0193] The exemplary implementation can also include an optional
horizontal vented furring strip that can be applied horizontally
(at the factory or in the field) to the backside of the
backer-board in between the furring strips. The grooved design of
the vented furring strip allows water vapor to escape while
providing a vertical fire break. This fire break can retard
vertical flame spread between the siding and sheathing. The vented
furring strip can be used on a shingle panel that is applied at or
near the top of the wall system for each level of the structure as
shown in FIG. 3.
[0194] Real Western Red Cedar Shingles on a solid, durable, Western
Red Cedar backer-board provide two layers of laminated wood--one of
nature's best insulators. This two-ply "Cedar on Cedar" design,
coupled with factory installed furring system, (which creates a
dead air space between the siding and sheathing) add significantly
to the energy efficiency of the wall system.
[0195] The siding panel can be available in Even-Butt,
Staggered-Butt and Fancy Cut designs in 7'' standard exposures. A
5'' exposure can be also available in the Even-Butt design. These
standard exposures and designs provide a wide-range of
architectural options. The Premier Panel.TM. is also available in a
variety of custom variations to meet special architectural
needs.
[0196] The siding panel can be applied directly to studs 16'' O.C.
over a vapor barrier and/or rigid foam. This reduces sheathing
costs where codes allow an engineered shear option. (the siding
panel does not provide shear values).
[0197] The exemplary implementation can have a two-ply "Cedar on
Cedar" design to result in a panel with the rigidity necessary to
cover horizontal wall spans without undesirable deflection, while
still having the flexibility to be used in architectural features
requiring curvature of the panel.
[0198] One hour fire rated wall construction can be achieved by
using a minimum 1/2'' gypsum wallboard on both sides of a 2.times.4
stud wall, 16'' O.C. (Subject to completion of fire test).
[0199] While the present system has been described and illustrated
by way of several implementations, it should be understood that
this description is intended to be illustrative only. The present
system is not intended to be limited to just these particular
implementations. One of ordinary skill in the art will recognize
that certain of the features described above may be modified yet
are still within the scope of the present system.
