Definitions

  • the present invention is directed to a rigid panel or board made from synthetic materials and which is suitable for use as a backing support against which a variety of coverings may be installed.
  • the inventive board comprises at least a core layer made from a densified foam material having a predetermined structural integrity with sufficient rigidity suitable for installation and the attachment of a variety of coverings thereon.
  • the densified foam material of the core layer has a predetermined structural integrity to allow a user to make a score line on the board and sever it into smaller pieces.
  • plywood underlayment products and/or cement based products are often tedious, labor intensive and time consuming.
  • plywood sheets and cement based mixtures are often heavy and cumbersome, plus cement based mixtures and related products need time to cure or harden.
  • cement boards are useful in those areas of a building structure where water and moisture occur, such as in kitchens and bathrooms, and are commonly used as wall surfaces in bathrooms due to their ability to withstand relatively high levels of humidity and to serve as a backing support against which tiles of marble, stone and the like can be applied.
  • drywall which are made of gypsum plaster and also used on interior walls of a building structure, do not typically serve as a backing support for tiles, and also, are very susceptible to moisture and/or humidity and therefore, are not suitable for wet environments such as in a bathroom, near a shower, etc.
  • a new backing support product could be made out of a material that is relatively thin, relatively lightweight, not cementitious, and which also offers waterproofing properties. If any such improved backing support were developed, it should also be sufficiently rigid so as to be capable of being secured to a surface without causing any damage to the backing support itself, while also capable of supporting a covering without being damaged. Further, if any such improved backing support were developed, it should also have an ability to be readily modified or cut into any desired sizes or shape upon installation. Ideally, if any such improved backing support were developed, it would be capable of offering certain sound proofing or sound attenuation properties, which is desirable for use in multi-story developments such as condominiums, hotels, etc.
  • the present invention is intended to present a solution to these and other needs which remain in this field of art, and as such, is directed to a panel or board made of synthetic materials, and having a structural integrity and sufficient rigidity to permit installation on a surface and to support a variety of coverings thereon.
  • the inventive board overcomes some of the drawbacks of existing plywood underlayment and cement based products as the inventive board is waterproof and can therefore be used on both horizontal and vertical surfaces, and also in different areas of a building such as bathrooms, other areas likely to be exposed to moisture or humidity, as well as with many desired types of flooring surface(s).
  • the coverings which may be installed in overlying supported relation to the inventive panel or board, may include tiles made of stone, marble, granite, and the like but also others such as, but not limited to, laminate flooring, vinyl composite tiles (VCT), wood planks and other flooring products.
  • the panel or board can be formed to include a dye or colorant(s) in order to coordinate with a particular color scheme for the surrounding area, and in other embodiments can itself be directly painted, so that in some instances, the present invention can be used to finish a building floor, wall or other surface, and its use with other coverings is not necessary.
  • the panel or board of the present invention which can be formed to offer various sizes and dimensions, comprises a core layer having a first or top surface, an oppositely disposed second or bottom surface, and a substantially uniform thickness that in some embodiments is within a range of generally about 4 millimeters to about 6 millimeters, and ideally about 5 millimeters.
  • a textured surface is formed on at least a portion of either the first top surface or the second bottom surface.
  • the textured surface comprises, in at least one embodiment, an abrasive finish formed at least partially, if not entirely, on either the first or second surface, to facilitate use with an adhesive or other material such as “thin-set” or mortar.
  • both surfaces may include a textured surface, such as but not limited to, a substantially abrasive finish on one of these surfaces and a substantially smooth finish on the other, which may be desirable in other instances.
  • the panel or board of the present invention has a core layer comprising a densified foam material having an optimal density that achieves balance between rigidity and severability.
  • the densified foam material has a predetermined structural integrity so as to be sufficiently rigid to permit installation onto a selected surface without causing damage to the panel or board, and also, adequate structural support to one or more coverings thereon, some of which may be heavy.
  • the predetermined structural integrity of the densified foam material is sufficiently severable such that a user can cut or “score” a line on the panel or board with a box-cutter, knife or other cutting tool, and subsequently “snap” the panel or board into smaller pieces.
  • the densified foam material will have a optimal density ranging from generally about 450 kg/m 3 to about 550 kg/m 3 , although in one or more preferred embodiments, this will be generally about 500 kg/m 3 .
  • the panel or board of the present invention can be extruded from a foamed high density polyvinyl (PVC) composition comprising in at least one embodiment generally equal amounts of a polyvinyl chloride (PVC) material and calcium powder, as well as stabilizing agents and foaming agents, such as but not limited to a composition of generally about 47% of PVC, and generally about 47% of calcium powder, a stabilizer agent of generally about 3% and a foaming agent of generally about 3%.
  • PVC polyvinyl chloride
  • the densified foam material composition and density thereof contribute to the waterproofing properties of the invention, making it ideal for use in moist environments such as kitchens, bathrooms, and showers. It should be noted, however, that in other embodiments, the core layer of the inventive panel or board, including the densified foam material may also comprise other materials and/or formulations.

  • Other coverings can also be used with the inventive board 10 , such as, but not limited to, laminate flooring, vinyl composite tiles (VCT), wood planks and other flooring products.
  • VCT vinyl composite tiles
  • other coverings or finish products which may also require a flat surface for installation are also within the scope of the present invention.
  • the panel or board 10 of the present invention comprises at least a core layer, generally represented as 20 .

  • the core layer 20 will preferably have a uniform thickness between its top surface 12 and bottom surface 14 and be in a range of generally about 4 millimeters to 6 millimeters, although in a preferred embodiment, this thickness will be generally 5 millimeters.
