This disclosure relates generally to lap siding systems and apparatus for use on the exteriors of residential and commercial buildings. Lap siding systems generally provide aesthetically pleasing, low maintenance exteriors to a variety of buildings by attaching overlapping horizontal or vertical boards or planks to the exterior of a building. For simplicity, the term “plank” includes boards, slats, and panels. Planks may be made of wood, cementitious material, plastic, metal, glass, various types of fiber and filler material, composites of these materials and other materials known in the art.
A common problem in construction is that of weatherproofing structural junctures in lap siding systems, such as between planks, at corners, at junctions between planks and other structural features such as windows and doors, and at junctions between planks and other decorative features such as trim, appliqués, and similar features. Weatherproofing serves the goal of protecting the underlying structure of the building from the damage associated with water seepage that can result in flourishing termite, pest, and mold populations. Damage resulting from water seepage may also result in rotting, swelling, and warping of the planks of the lap siding system, the trim, appliqués, and other features, and/or the underlying structure. Water seepage may also result in a reduction of the effectiveness of insulation, cracks in the masonry, loosening of the siding system from the underlying structure of the building, and the like.
The standard practice in weatherproofing is to seal and back the juncture with flashing. Typically, such flashing is made of metal or vinyl and positioned under the juncture and affixed to the underlying structure. This type of flashing is normally placed along the entire seam created by the juncture.
The flashing is usually sealed against the underlying structure with caulk. However, caulk tends to shrink over time. Additionally, the weathering and dissimilar thermal expansion and contraction of the flashing, siding, and caulk often leads to failure of the seal so that water seeps behind the siding and may result in water damage to the lap siding system and underlying structure. Furthermore, the exposed junctions, caulk, and flashing may be unsightly.
Additionally, the bottommost horizontal planks and starter strips of currently available lap siding systems abut or contact a portion of the foundation or wainscot. Water often collects and sits in this juncture causing water damage to the bottommost planks and starter strips. Furthermore, the bottommost planks and starter strips are often disposed so close to the underlying structure of the building that water wicks up between the bottommost planks, starter strips, and the underlying structure of the building, which increases the likelihood that significant water damage will occur.
Another problem in the installation of a lap siding system on a building is the difficulty in evenly attaching each plank to the underlying structure. The conventional method of installation requires constant measuring of plank position and adjustment, which is time-consuming.
With some lap siding systems, a clearance between the roof and the lap siding system of at least two inches may be required. Flashing and counter flashing may be installed and caulked to protect the gap from wind and water. However, this gap may be unsightly and, like the junctions discussed above, the caulk and flashing may fail so that water is able to seep behind the flashing.
Most lap siding systems are secured to the underlying structure by top nailing, which is also referred to as blind nailing. The nail used in blind nailing is driven through the plank near the top of the plank such that the nail head would be covered by the next higher plank as it overlaps the top of the lower plank. Each progressively higher plank overlaps the top nail of the lower plank, thus rendering it a blind nail. Blind nailing secures the planks to the structure and provides an aesthetically pleasing appearance to the lap siding. However, with the only fastening mechanism being applied at the tops of the planks, the lower portion of the planks is unsecured. In the event of moderate or high winds, it is common for wind to get under the lower edge of the plank and apply upward and/or outward pressure on the plank, causing it to loosen, bend, warp, or even separate from the building. Accordingly, it is common in many parts of the world to secure the planks with both blind nails and face nails. The face nails are driven through the lower or bottom portion of the planks and into the underlying plank and/or the underlying structure.
While the face nails can provide additional strength to the coupling of the plank to the structure, the face nails are known to cause several concerns. As one example, the face nails are often considered to be unsightly and attempts to paint over them are often unsuccessful for a number of reasons. In some circumstances, the face nails can be driven too far into the plank exposing siding fibers. The exposed siding fibers are then open to the elements and, if the face nail is countersunk too far, the structural integrity of the siding plank may be impaired. Additionally, the face nails, whether driven too far or not, create another opening in the exterior siding and a possible channel for water to be wicked, or otherwise passed, from the exterior of the siding to the interior of the siding where it can cause one or more of the problems identified above.
Proper installation of lap siding with face nails requires each face nail to be caulked and sealed to resist moisture from penetrating through the siding. Other than being incredibly time-consuming to caulk each face nail, the caulking also presents long term problems due to differences in materials between the caulk and the planks, different expansion and contraction rates, and different weathering patterns between the materials. Accordingly, even if the caulking and painting can be done initially to avoid the aesthetic problems and to prevent moisture from penetrating the siding at the face nail, the adequacy of the seal generally deteriorates over time and the aesthetic issues generally arise as the color of the paint over caulk changes tone differently than the paint over the siding plank.
Conventional lap siding relies heavily on attempts to weatherproof the structure by sealing the structure against the exterior elements, such as by caulking the joints between planks and at junctures where planks terminate at other structural or decorative features, such as windows, doors, trim, or changes in the contour of the underlying structure. However, time has shown that a perfect and complete seal of a structure against the elements is difficult and can have negative consequences for the structure and its occupants. As one example, it is generally accepted that homes need to breath. Allowing a home to breath is believed to improve the longevity of the structure and improve the living conditions in the home. In the attempts to seal a home against the exterior elements, siding planks are generally placed close together and caulking is applied between the siding planks and/or between siding planks and other materials forming the exterior of the structure. When these caulking seals are freshly applied, assuming the seals are done correctly, the home cannot breath. There is generally no air flow behind the siding planks or other features.
Additionally, when one of these caulked seals fails and allows a little bit of moisture to penetrate the exterior shell of the structure, the moisture is effectively trapped between the exterior shell and the underlying structure. As suggested above, moisture can penetrate the exterior shell in a number of ways, such as through the face nails and/or the joints between planks, particularly when the caulking ages and weathers. Once the moisture is trapped between the exterior shell and the underlying structure, the moisture can lead to several problems including rotting of the structure and/or siding planks, allowing mold to grow between the siding planks and the structure, and attracting a variety of pests. Because of the extremely limited airflow between the structure and the siding planks, the moisture will not dry out very quickly. In many circumstances, the moisture may not sufficiently dry out in time to prevent the negative consequences of the moisture.
The apparatus and system of the present disclosure has been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not been fully solved by currently available lap siding systems and apparatus. Thus, the present disclosure provides a lap siding system and apparatus for providing an aesthetically pleasing, low maintenance exterior to a variety of buildings.
In accordance with the technology as embodied and broadly described herein in the preferred embodiment, a lap siding system is provided. The lap siding system may include a plurality of planks having a first end and a second end. Additionally, one or more of the ends of each plank may be operatively associated with another exterior member of the building, such as another siding plank, a door trim member, a window trim member, a corner member, or other such members, one or more of which may also comprise part of the lap siding system of the present disclosure. When installed on a building, a portion of each plank may overlap a part of another plank. The planks may be installed on the building such that there is a space provided between at least a portion of the planks and the underlying structure of the building, which may also be referred to as the substructure of the building.
The space provided between the substructure and the planks may be referred to as a ventilation channel. Accordingly, a building covered with multiple planks as part of a lap siding system may include multiple ventilation channels between the planks and the substructure. In order to facilitate the movement of air through the one or more ventilation channels, the planks of the lap siding system and the complementary members, such as corner trim, door trim, window trim, etc., may be associated in a manner to provide a complementary ventilation channel between the associated end of the plank and the structures of the complementary members. One or more complementary ventilation channels may be provided in a building implementing the lap siding system of the present disclosure. The complementary ventilation channels may be adapted to extend between at least two ventilation channels.
These and other features and advantages of the present description will become more fully apparent from the following description and appended numbered paragraphs, or may be learned by the practice of the invention as set forth hereinafter.
In order that the manner in which the above-recited and other features and advantages of the present disclosure are obtained will be readily understood, a more particular description of the present systems and methods briefly described above will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the systems and methods and are not therefore to be considered to be limiting of its scope, the present technology will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
The presently preferred embodiments will be best understood by reference to the drawings. It will be readily understood that the components, as generally described and illustrated in the figures herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the lap siding system, as represented in
The lap siding system 112 of the present disclosure may provide numerous benefits to the building it covers. For example, the present lap siding system may promote the weatherproofing of the building through the use of flashings at junctures between planks and between planks and other elements of the plank siding system 112. Additionally, the present lap siding system may facilitate the installation of the planks and other elements through the use of interlocking members between the planks. Some aspects of these features will be described herein; other aspects have been previously described in United States patent application entitled WEATHERPROOF LAP SIDING SYSTEM, application Ser. No. 11/271,633, filed Nov. 10, 2005, which is incorporated herein by reference in its entirety for all purposes.
With continued reference to
For example, the lap siding system 112 may include decorative appliqués such as decorative shutters, window sills, window headers, sill boxes, masonry headers, door headers and gables. Additionally, the lap siding system 112 may include a plurality of planks, flashings, trim members and other complementary elements 120. The various components of the lap siding system are adapted to be easily installed in a variety of configurations. Additionally, in some configurations, the present lap siding system provides weatherproofing benefits to the substructure as well.
As described above, a persistent problem in weatherproofing buildings is the possibility for moisture to wick, seep, or otherwise get behind the exterior materials and to become trapped between the exterior materials and the substructure of the building. Prior efforts have attempted to seal the exterior completely through the use of caulking and sealing between the various exterior materials. However, as discussed in the above incorporated application, such weatherproofing efforts have been less than fully successful, particularly when elements of aesthetics and the impact of time are considered.
The lap siding systems 112 of the present disclosure utilize air, and particularly the possibility of moving air, to increase the opportunities for any moisture trapped between the exterior materials and the substructure to be dried out before leading to the problems identified above, such as rot, mold, and/or pests. One example of the associations between the planks 114, the complementary members 120, and the substructure is shown in
Flashings 140 may be associated with the legs of the corner trim member 122 in any suitable manner. When the corner trim member 122 is attached to the building, the flashings 140 and the legs may be coupled together in a manner to provide a corner trim member 122 that is at least somewhat, if not substantially, difficult to separate into its component parts without breakage. The coupling between the flashing 140 and the remainder of the corner trim member 122 will be described in more detail below.
As illustrated, the flashings 140 are secured to a building 100 by means of fasteners 172, wherein the fasteners 172 are inserted through an extended portion 162 of the flashings 140. The lap siding system 112 further comprises an interlocking clip 198. The interlocking clip 198 is placed over an upper plank 208 such that a first portion 300 of the interlocking clip 198 is positioned between the upper plank 208 and the building 100 while a second portion 302 of the interlocking clip 198 is position over the outer surface of the upper plank 208. The configuration and use of the interlocking clip 198 will become more apparent in the discussion of
As configured, the corner trim member 122 comprises a plurality of ventilation channels 180. Each ventilation channel 180 provides air circulation to the individual components of the lap siding system 112 thereby providing an escape for undesirable moisture within the system 112. Additionally, each individual ventilation channel 180 may be in fluid communication with another ventilation channel 180 such that a ventilation system is created within the lap siding system 112. The specifics of the ventilation channels 180 and their various subcomponents will be discussed in detail below in connection with
As illustrated, the leg member 134 includes a mouth 148 having a lower lip 150 and an upper lip 152. The mouth 148 is adapted to receive at least a portion of the flashing 140 and may be configured to retain a portion of the flashing 140 within the mouth 148. The mouth 148 of the leg member 134 may include a variety of elements suitable for receiving and retaining portions of the flashing 140, at least some of which may vary depending on the configuration of the flashing 140. For example, the mouth 148 may include a channel 154 adapted to receive a portion of the flashing 140 and may include an indentation 156 in the upper lip 152 for catching a flange portion 166 of the flashing 140.
With reference to
Additionally or alternatively, the flashing 140 may be coupled to the remaining portions of the corner trim member 122 in other suitable manners. For example a portion of the flashing may be coupled to the leg member 134 by fasteners, adhesives, or other known coupling agents. Preferred configurations would allow the fastening means to be hidden from view when the corner trim member 122 is applied to the building. One exemplary alternative may include a flashing with a simplified head portion adapted to help position the flashing 140 relative to the leg member 134 and may include a fastening means hidden from view, such as a screw or other fastener through the back side of the fastener 140 and into the back side of the leg member 134. One example of such a simplified head configuration is shown and described in more detail in connection with
With continued reference to
The top view illustrated in
With continuing reference to
Regardless of how the water finds its way into a siding system, moisture retained within a siding system leads to certain problems for the structure as previously discussed. Therefore, the present invention provides a plurality of ventilation channels 180 thereby providing an escape route for moisture trapped within the lap siding system 112. Specifically, the ventilation channels 180 created between the corner trim member 122 and the substructure of the building are adapted to allow air to move behind the corner trim member 122 thereby drying out moisture that may be present behind the trim.
In order to maximize the size of the ventilation channels 180 and to minimize the surface area of the corner trim member 122 in direct contact with the substructure, the platform portion 160 of the flashing 140 may be configured with multiple platform supports 192 as illustrated in
The ventilation channels 180 created by the present lap siding systems 112 may have varying degrees of air flow through the channels depending on the location of the channel on the structure and depending on the ambient weather conditions. For example, the degree of ventilation, or air flow rate, may increase on a windy day compared to a calm day. Continuing with the example of the corner trim member 122, the corner ventilation channel 184 may be adapted to principally rely upon air entering the channel from the top or bottom of the channel (e.g., from the soffit region or adjacent the foundation). In such circumstances, the top of the corner ventilation channel 184 is configured in fluid communication with ventilation channels in the soffit and/or roof structure of the building. The bottom of the corner ventilation channel 184 may be open to the atmosphere to allow air flow in and out. Additionally or alternatively, the bottom of the corner ventilation channel 184 may be shielded to a greater or lesser degree by one or more systems adapted to prevent water from entering the corner ventilation channel 184 while still allowing air to flow through the corner ventilation channel.
While the ventilated lap siding systems of the present disclosure are primarily passive ventilation systems (i.e., systems that do not utilize or rely upon mechanical means to drive air through the ventilation channels 180), lap siding systems within the scope of the present disclosure may be adapted and installed to facilitate a driven ventilation system. For example, a fan may be positioned near to an opening in the ventilation system to blow air in the desired direction to increase air flow in one or more of the ventilation channels. Clean-up operations following a flood or other event in which an exceptionally large amount of water contacts the building or in which water contacts the building in unexpected manners (such as from the ground up rather than otherwise) present one example of when a driven ventilation system may be economically implemented. An air pump with a hose may be coupled to an inlet of one or more of the ventilation channels 180 and air may be pumped through the channels at a suitable flow rate to accelerate the drying of the building. To the extent that two or more of the ventilation channels are in fluid communication, the mechanical, driven ventilation system will be simplified.
Additionally, a complementary ventilation channel 218 is provided to allow for the natural expansion and contraction of the siding members 208, 212 due to changes in the climate and temperature. In addition to providing ventilation, the complementary ventilation channel 218 provides a physical gap between the siding members 208, 212 and the flashing 140. During expansion, the complementary ventilation channel 218 provides a space into which the siding members 208, 212 may expand rather than buckling and/or dislodging from the substructure 100. The complementary ventilation channel 218 in conjunction with the plank channel 190 provides sufficient clearance between the siding members 208, 212, the complementary corner members 134, 136 and the flashing 140 whereby the siding members 208, 212 may expand and contract without undesirable binding and/or rubbing on other components of the lap siding system 112.
The angled configuration of tradition siding systems is replicated within the current lap siding system 112 by the use of shims 274. The shims 274 may be modified to form a continuous structure capable of filling the voids between multiple overlapping components such as siding planks and an even and/or uneven building substructure 100. Additionally, the shims 274 may be formed to include any material, shape, size, dimensions, orientation, and/or other features in order to fill undesirable voids within the lap siding system 212. Finally, the shims 274 may be secured, attached and/or installed to any component in any order of installation using any attachment mechanism or method.
Referring now to
For example, in the event that an apron (not shown) is disposed below the lowermost layer of planks, the starter flashing 196 may include clips or braces to facilitate positioning of the starter flashing 196 relative to the apron. Similarly, the starter flashings that may be used may include drainage features and/or water control features to help direct water away from whatever may be underlying the lowermost layer of planks. An embodiment of an alternative starter flashing is discussed below in connection with
The contours of the surfaces of the interlocking clip 198, the starter flashing 196 and the interlocking groove 206 may vary depending on the preferences of the manufacturer and the circumstances of the installation. However, when mating beveled surfaces are utilized, a bevel of between about 30° and about 60° may be suitable for the interlocking clip 198, the starter flashing 196 and the interlocking groove 206.
While not necessary for the purposes of the ventilated siding system of the present disclosure, the interaction between the interlocking clip 198 and the interlocking groove 206 may provide the lap siding system with a variety of features. For example, the interlocking relationship between the clip 198 and the groove 206 may couple the lower region 194 of the plank 208 to the building 100, such as by coupling to the next lower plank 212 or to a starter flashing 196 as illustrated in
Additionally or alternatively, the interlocking clips 198 and the interlocking groove 206 may be adapted to provide a vent between the subsequent planks. As illustrated most clearly in
The vent 214 may be adapted to advantageously allow ambient air to flow into the plank ventilation channels 216 for subsequent flow into one or more other ventilation channels 180. The vents 214 and the relationship between the upper planks 208 and the lower planks 212 may be adapted to provide sufficient coverage of the vent 214 that moisture would not be able enter the vent, except for during the infrequent times when water moves upward, such as during flooding. Additionally, the relationship between the upper and lower planks 208, 212 may include sufficient spacing to limit and/or prevent wicking between the two planks. The interlocking clip 198 and the interlocking groove 206 may be adapted to create a vent 214 having a gap of varying thickness between the upper and lower planks. For example, the spacing between the planks may provide a vent 214 as small as about 0.1 centimeters thick or as large as 0.5 centimeters.

Turning now to
Frieze boards 224 may be made of any variety of suitable materials, including wood, composite wood, engineered wood, cementitious materials, vinyl, and metals. Frieze boards 224 may also be adapted to cooperate with one or more flashings 140 wherein the one or more flashings 140 may comprise a host of variations directed towards adapting the frieze board 224 for use within the present lap siding system 112.
Turning now to the exemplary horizontal frieze 226 of
Additionally or alternatively, the extension portion 232 may provide the installers with a facilitated installation method. For example, the horizontal frieze 226 may be secured to the building 100 with fasteners 172 through the extension portion 232 rather than through the material of the frieze member itself. In addition to facilitating the installation, the use of the extension portion 232 for coupling the frieze to the building maintains the integrity of the frieze board 224 thereby limiting the amount of moisture that can penetrate behind the frieze board 224.
The support portion 234 may be substantially similar to the support portion 160 of the previous illustrations. The support portion 234, as well as the remainder of the flashing 140, may be made of any suitable materials, such as plastics, metals, composite materials, and the like. The configuration of the support portion 234 and the remainder of the flashing may depend somewhat on the materials selected as some materials are more easily configurable than others. As described above, the support portion 234 may be adapted to provide ventilation channels 180 behind the frieze board 224.
Additionally, the support portion 234 may provide a space for the plank flashing 228 to be coupled to the exterior member 238 of the horizontal frieze 226, which may be similar to or different from the configuration shown in greater detail above, and which may include the use of a fastener through the support portion 234 and into the exterior member 238. For the purposes of brevity, the details of the ventilation channels 180 and the relationship between the support portion and the ventilation channels 180 will be summarized by reference to the above discussion of the ventilation channels of the corner member 122. The frieze ventilation channels 240 may be adapted to be in fluid communication with at least one other ventilation channel 180, such as the corner ventilation channel 186.
The plank flashing 228 further comprises a head portion 282 configured to compatibly engage a mouth portion 242 of the horizontal frieze 226. The mouth portion 242 is formed at one end of the frieze 226 wherein the mouth portion 242 extends along the length of the frieze 226 defining the recessed space between an outer lip 284 and an inner lip 286 of the frieze 226. The head portion 282 of the plank flashing 228 further comprises at least one support portion 288 whereby at least one ventilation channel 180 is created between the head portion 282 and the inner surface of the inner lip 286.
The head portion 236 of the plank flashing 228 is noticeably different from the head portion 158 illustrated above. As discussed above, the head portion 236, however, provides many of the same functionality of the head portion 158. For example, the head portion 236, in cooperation with the mouth portion 242 in the exterior member 238, facilitates the proper alignment of the plank flashing 228 relative to the exterior member 238.
Additionally or alternatively, the head portion 236 in cooperation with the mouth portion 242 and a suitable adhesive may provide sufficient bonding strength between the plank flashing 228 and the exterior member 232 to not require additional fasteners. The head portion 236 and the head portion 158 may be interchangeable and are examples of the various couplings that may be provided between the flashings and the exterior members. The selection of a particular configuration for the head portion may depend on the exterior member to which the flashing is being connected and/or the preferences of the manufacturer or installer.
The plank flashing 228 further comprises a flange extension 290. The flange extension 290 comprises an outwardly extended portion of the plank flashing 228 thereby providing a plank channel 292 adapted to receive an end of the horizontal plank 116. The flange extension 290 further provides protection to the channeled end of the horizontal plank 116 as well as provides an aesthetic shielding of any exposed fasteners 172.
The soffit flashing 230 is substantially similar to the plank flashing 228, including an extension portion 232, a support potion 234, and a head portion 236. The support portion 234 may provide at least one of the features described above for the support portion, including the creation of ventilation channels 180 and the coupling of the flashing 230 to the exterior member 100. Additionally, the head portion 236 may provide the functionality described above, including facilitating the coupling of the soffit flashing to the exterior member.
As illustrated, the head portion 236 of the soffit flashing 230 is different from the head portion of the flashing associated with the corner member 122 and the head portion of the plank flashing 228. The head portion 236 of the soffit flashing 230 comprises a j-shape configured to compatibly engage an upper portion 296 of the horizontal frieze 226. Specifically, the head portion 236 of the soffit flashing 230 comprises a tab 298 for engaging a groove 304 of the horizontal frieze 226. The groove 304 runs the entire length of the frieze 226 and is located towards the upper end of the frieze. The head portion 236 of the soffit flashing 230 is yet another example of the various head portion configurations that are within the scope of the present disclosure.
The extension portion 232 of the soffit flashing 230, as illustrated in
Additionally or alternatively, the soffit channel 244 may be adapted to facilitate ventilation within and among the soffit 128 and fascia elements (not shown). Additionally or alternatively, the soffit channel 244 may be adapted to provide fluid communication between one or more ventilation channels 180 and 240 associated with the complementary member 120 and/or one or more ventilation channels associated with other parts of the building 100. Additionally or alternatively, the soffit channel 244 may be adapted to facilitate the installation of the soffit members 128. As illustrated, the soffit flashing 230 is disposed at the uppermost region of the frieze board 224 when installed. The soffit member 128 may be installed by sliding the rear edge of the soffit member (i.e., the edge that will be disposed adjacent to the building 100) into the soffit channel 244 and resting the rear portion of the soffit member 128 on the upper side of the head portion 236 of the soffit flashing 230 as illustrated.
Referring now to
However, because the vertical frieze 246 is adapted to cooperate with vertical planks 118, which may also be referred to as “board and batten” or “plank and batten” siding, the lowermost region may vary from the exemplary horizontal friezes shown in
The base flashing 248 may be constructed of any suitable material or combination of materials and may be coupled to the exterior member 238 of the vertical frieze 246 in any suitable manner. As illustrated, some configurations of suitable vertical friezes 246 may be adapted to allow air flow from behind the exterior member 238 to ventilation channels 180 associated with the vertical planks 118.
The interaction of the vertical planks 118 and the base flashing 248 is similar to the interaction of the horizontal planks 116 and the plank flashing 228. For example, the base flashing 248 comprises a flange extension 308 which defines a plank channel 310 for engaging an upper end of a vertical plank 118. The flange extension 308 further provides protection to the channeled end of the vertical plank 118 as well as provides an aesthetic shielding of any exposed fasteners 172. The flange extension 308 is further configured to provide a ventilation channel 180 as well as to provide adequate space to accommodate an end portion of a batten 254 as illustrated in
While the physical dimensions of the horizontal frieze 226 and the vertical frieze 246 are the same, the interaction of base flashing 248 with the vertical frieze 246 is noticeably different from the interaction of the horizontal frieze 226 and the plank flashing 228. Of particular notice is the gutter 312 formed between an upward extension 314 of the flange extension 308 and the outer surface of the vertical frieze 246. As configured, the gutter 312 provides a channel for collecting water as well as provides an aesthetic shielding of the outer lip 284. It will also be noted that the base flashing 248 as illustrated in

The board stop member 270 illustrated is optional but may be included to help ensure proper installation of the boards and battens to preserve the ventilation channels. In addition to use of the stop member 270 in conjunction with the battens 254, 256, suitable board stop members may be provided and/or incorporated into other members of the lap siding system 112. For example, the flashing of the corner trim member 122 may be adapted to provide a stop member configured to maintain the horizontal planks 114 a predetermined distance away from the head and support portions of the flashing, to thereby maintain a sufficiently-sized complementary ventilation channel 180. Similar adaptations may be made to the remaining flashings and relationships described herein and are within the scope of the present disclosure.
The apron flashing 318 may comprise any configuration suitable to adjoin the apron member 316 to the remainder of the lap siding system 112. As illustrated, the apron flashing comprises an extension portion 232 and a support portion 234; each utilized according to the prior discussion for attaching the apron flashing 318 to the building 100 (not shown) and providing ventilation throughout the lap siding system 100. Additionally, the apron flashing 318 comprises a plank channel 324 for compatibly receiving a lower portion of the lap siding system 112 components. Specifically, as shown in
The apron flashing 318 further comprises a head portion 326 similar to the head portion 236 of the soffit flashing 230. The head portion 326 comprises a tap feature 328 adapted to compatibly engage a groove 330 as formed on the outer surface of the upper region 320 of the apron member 316. Other features of the head portion 326 may include a gutter 312 for collecting and channeling heavy moisture, as well as flange 332 for directing heavy moisture away from the outer surface of the apron member 316.
While not specifically illustrated and discussed in the present disclosure, the remaining complementary members 120, including door trim members 124, window trim members 126, and other members that may be used in connection with the lap siding systems 112 may include flashings and other components adapted to improve the ventilation between the substructure of the building and the various components that comprise the exterior shell of the building.
For example, a trim clip (not shown) may be incorporated into the lap siding system 112 to provide ventilation as well as secure various complementary members 120 to the building 100. Use of a trim clip within the present system 112 is accomplished so as to eliminate the need for nails or other fasteners 172 to extend through the exterior surface of the complementary member 120. For example, a trim clip may be first attached to a building 100 with a fastener 172 and thereafter be attached to a complementary member 120 by an adhesive or other fastener that is aesthetically pleasing to the overall system 112.
Accordingly, and as introduced at the outset, the present disclosure is directed toward lap siding systems including planks and complementary members, at least one of which is adapted to provide and/or increase the ventilation between the planks and/or complementary members and the substructure of the building.
