  • the presence of the hollow voids within the panel can be beneficial depending upon the end application of the siding sheets 12.

  • a siding sheet 12 can be provided having multiple gradations of a realistic mark coloration which, depending upon the bark species, may include multiple variations of gray, brown, and with streaks or patches of black and white.

For interior use, placement of panels is not dependent upon allowances for thermal expansion.

  • a number of grooves and indentations 21 and ridges 22 are defined within the surface of the siding sheet 12.

  • the synthetic bark surface because of the deep grooves and indentations patterns, offers a three-dimensional product face which simulates the aesthetic appearance of a natural bark siding product.
  • the bark facing of the present invention offers a textured surface which creates a series of shadows and areas of contrast which can be seen in all types of lighting.
  • the number, placement, and extent of the grooves and indentations 21 achieve a realistic bark appearance. As best seen in reference to Figures 5 and 10, a number of the grooves and indentations 21 define an included angle of at least about 45° (including some which are 90° or greater) within the siding sheet 12. The combination of the depth and the angled walls helps to simulate a realistic appearance of a tree bark.
  • the relatively flat regions such as the surface of ridges 22 may display the fine texture and detail of wood grain, as best seen in Figure 9, thereby simulating the appearance of a natural bark.
  • the textured surface of the simulated poplar bark maintains a tactile quality which, when touched, mimics the rough texture of a natural bark product.
  • the siding sheet 12 as best seen in cross section in Figures 5 and 6 defines a series of grooves and indentations in which at least a portion of said grooves and indentations defines a depth of at least 50 percent of the panel thickness. More preferably, at least some of the grooves extend a depth of at least about 75 percent of the panel thickness when measured from an upper surface to a lower surface of a panel thickness. The depth and degree of defined surface texture facilitates the appearance of a natural bark product. The deeper grooves and indentations also provide greater structural strength to the panel by better distribution of weight. Increased strength allows the siding sheet 12 to absorb impact better. Further, when used as a roofing material, the increased structural strength provided by the surface grooves and indentations helps support and distribute weight better such that the roofing material can be walked upon without damage.
  • the surface area of the upper ornamental surface is approximately 50 percent greater than the surface area of the corresponding flat bottom surface. Having a surface area which is at least about 50 percent greater than a corresponding flat surface provides for a realistic depth and appearance to the molded product. Furthermore, the numerous downwardly directed edges of the various grooves and indentations 21 increase the structural strength and rigidity of the ornamental surface of the panel as compared to a flat surface hollow molded product. The 50 percent or more increase in surface area contributes enormously to the desired simulated bark appearance and contributes to the functionality of the siding sheet 12.
  • the molded product presents a realistic depiction of a natural oak bark product.
  • the upper ridge lines are not necessarily smooth but form an uneven texture of shallow depressions and raised regions including a visible wood grain pattern as seen by reference numeral 34.
  • the grooves and indentations 21 and ridges 22 provide a realistic texture appearance both visually as well as providing a tactile sensation similar to a natural ⁇ ak bark product.
  • the increased surface area allows for a greater radiant cooling effect such that the siding more quickly radiates heat away from the underlying structure.
  • the ability to radiate heat prevents excessive heat accumulation and transfer to the adjacent dwelling.
  • the increase in surface area of the ornamental surface also helps to prevent build up of undesired heat. But for brief intervals when the sun is directly opposite a surface of the panel, the extensive grooves and indentations 21 and the 45 degree or greater wall angles defined by many of the grooves and indentations 21 provide some element of shade/shadow to at least portions of the exposed surfaces of the panels. The shaded portions help maintain an overall cooler surface as opposed to a completely flat surface.
  • the synthetic siding sheets 12 facilitate a similar weathering process. If desired, the molded siding sheets 12 will facilitate the accumulation and colonization by algae, moss, and similar plants which enhance the aesthetic appearance of the molded product. While such growth on a conventional flat siding material designed to simulate finished wood or a painted wood product is considered unsightly, the texture and appearance of the siding sheet 12 can be enhanced by such natural colonization.
  • the durable nature of the simulated bark siding sheets 12 can be easily cleaned using conventional pressure cleaning and/or bleaching techniques. Such techniques are potentially harmful to and shorten the life of natural wood siding or many conventional roofing products such as a wooden shake roof, asphalt roof, or composite shingle roofing materials.
  • a simulated bark siding material may be configured for use as a roofing product.
  • a flange area or backing 30 is defined which extends along a bottom of the sheet 12 and extends % in an upward direction as seen relative to a conventional pitch of a roof.
  • the backing 30 defines a series of apertures which can be used to secure the roofing panel to a roof.
  • subsequent panels can be placed in an overlapping position such that the flange region of each panel is positioned beneath the next adjacent roofing member.
  • the groove and indentation pattern 21 may be modified as desired such that the grooves are substantially continuous and/or are interconnected so as to drain from one panel to an adjacent panel.
  • the various channels and grooves may have some advantage in maintaining pockets of water or moisture which don't drain.
  • some roofing designs operate on an evaporative cooling concept in which the evaporation of water from the roofing material facilitates cooling of the building structure by preventing accumulation of heat in the roof. Accordingly, in temperate regions which receive frequent intervals of rain and warm temperatures, the extensive surface area beneath the upper surface of the panel may provide for an accumulated pool of moisture from rainfall, dew condensation, or sprinklers such that the siding sheet 12 facilitates an evaporative cooling process of the roof.
  • siding sheet 12 and roofing panel 12' illustrate the series of grooves and indentations some of which are continuous from one edge to an opposite edge and others which are discontinuous. This particular pattern of mixed continuous and discontinuous grooves more closely approximates the natural pattern of bark although this pattern may be modified to address the needs set forth above.
  • the shape and size of the decorative simulated bark siding sheet 12 or roofing panel 12' may be varied and adapted to achieve a number of different construction products. For instance, where a rustic look of a bark appearance is desired, the sheets 12 or panels 12' can be manufactured in a size and dimension for use as decorative door molding, window moldings, chair rails, crown molding, as well as used as exterior covering on exposed ceiling beams, porch or deck railings, and similar structures.

Abstract

L'invention concerne un panneau à composition synthétique dont la surface ressemble à l'écorce d'un arbre. Ledit panneau à composition synthétique possède une série de rainures irrégulières et d'indentations plus ou moins profondes. Les rainures ont un motif irrégulier, des angles et une profondeur qui donnent au panneau l'aspect d'un produit d'écorce d'arbre. Ce panneau est assez solide pour servir de produit de couverture, de revêtement intérieur ou de revêtement extérieur, et il peut également être transformé en finitions décoratives, par exemple des moulures de porte, des moulures de fenêtre ou des moulures d'huisserie.
