Definitions

  • the present disclosure relates to building panels and in particular to floor panels.
  • parquet floor panels comprising a core which is formed of a plurality of low-grade wood blocks (also termed “slats” or “lamellae”, which are arranged with their fiber direction perpendicular to a longitudinal direction of the floor panel.
  • the core is sandwiched between a decorative layer, typically of an about 3 mm wood surface layer, and a balancing layer, typically of an about 2 mm wood veneer.
  • the decorative layer and the balancing layer are glued to the core.
  • parquet floor panels examples include WO96/30177 A1 and US2005/0208255A1 . Further examples are provided in US2007/0292656A1 and US2004/0226243A1 .
  • the present invention aims generally at overcoming or alleviating some disadvantages of prior art floor panels, with a particular focus on reduction of cost.
  • a floor panel comprising a decorative layer and a core layer.
  • the core is arranged below the decorative layer when the floor panel is substantially horizontally oriented.
  • the core layer comprises a plurality of wood blocks arranged with their respective principal fiber directions substantially parallel with a plane defined by a major surface of the floor panel and substantially perpendicular to a principal direction of the floor panel.
  • the core layer comprises a plurality of second material blocks, which are made from a different material than said wood blocks, and along the principal direction of the floor panel, the core layer presents alternating portions formed of said wood blocks and of said second material blocks.
  • a "principal fiber direction” is defined as the direction along which most of the fibers of the wood block extend. Typically, the principal fiber direction substantially coincides with a longitudinal direction of the wood block since lumber is normally sawn so as to have its fibers extend substantially longitudinally.
  • the "major surface” is typically the upwardly or downwardly surface of a floor panel. These surfaces are typically parallel with each other.
  • a "principal direction" of the floor panel may be a longitudinal direction in a case where the floor panel is elongate (i.e. substantially rectangular and non-square).
  • the principal direction may be a direction which is substantially parallel with a direction along which another layer, e.g. the decorative layer and/or the balancing layer, forming part of the floor panel, presents its major bending strength and/or major tensile strength, such as a principal fiber direction of the decorative layer and/or of the balancing layer.
  • a "second material block” is understood as a block of material which is different from the material of the wood blocks.
  • the second material blocks may e.g. be of generally lower quality (strength and/or stiffness) and/or cost than the wood blocks.
  • the second material blocks mainly serve to fill the space between the wood blocks, and possibly to provide sound reduction.
  • a floor panel comprising a plurality of second material blocks may be produced at reduced cost compared with a floor panel comprising only wood blocks, since such second material may be less costly than even the lowest quality wood.
  • the second material may reduce weight of the floor panel as compared to a floor panel comprising only wood, thus reducing cost of transportation and facilitating installation.
  • a total length of the second material blocks may be less than a total length of the wood blocks.
  • a total length of the second material blocks may be more than 5%, preferably more than 10%, 20%, 30% or 40% of the total length of the floor panel. Typically, the total length of the second material blocks is less than 50% of the total length of the floor panel.
  • the second material blocks have lower density than said wood blocks and/or lower tensile strength in a direction parallel to said principal fiber directions than said wood blocks.
  • the second material blocks may comprise expanded polymer material blocks, such as at least one of expanded polyethylene, expanded polypropylene and expanded polystyrene extruded polystyrene foam.
  • the second material blocks may comprise an engineered wood product.
  • Non-limiting examples of engineered wood products include fiberboards, chip boards, particle boards, and reconstituted wood.
  • the second material blocks may comprise a non-expanded polymer material comprising filler material.

  • the wood blocks may comprise wood blocks of a quality which is lower than or equal to G4-2/G2-2 of the European EN 1611-1 standard of 2000, preferably lower than or equal to G4-3/G2-3 or lower than or equal to G4-4/G2-4.
  • the wood blocks may also, or as an alternative, comprise, or consist essentially of, wood blocks of a strength class, which is lower than or equal to C18 of the EN 338 standard, preferably lower than or equal to C16 or lower than or equal to C14.
  • wood blocks which are of low or very low quality, and hence cost, may be used to a great extent.
  • the core layer may further comprise a reinforcing inset portion, which may be provided at a short side edge portion of the floor panel.
  • the core layer of the floor panel may consist of about 80-99 % by volume, possibly 90-95 % by volume, of alternating wood and second material blocks.
  • the remainder may consist of, inter alia, inset pieces, adapted to provide specific parts of the locking system.
  • the second material blocks may be provided with surface coating at an edge portion where said second material blocks are exposed.
  • the second material blocks may present a portion of increased density at an edge portion where said second material blocks are exposed.

  • the second material blocks have lower density than said wood blocks and/or lower tensile strength in a direction parallel to said principal fiber directions than said wood blocks.
  • the method may further comprise forming locking means along said principal direction of the floor panel blank.
