Definitions

  • the present invention relates to flooring boards and to a process for manufacturing such flooring boards.
  • the material used has good resistance against abrasion, low flammability, low VOC emissions, good sound dampening, mechanical properties and allows for ease of installation.
  • wood based materials engineered wood, wood-based high density fibreboard (HDF)
  • HDF high density fibreboard
  • tiles can be fragile because they may eventually crack when subjected to a drop impact. This is a result of the relatively high modulus of elasticity of the tiles which are made of materials such as ceramics or quarried stone. Because of the rigidity of the tile, the energy transferred to the tile upon impact cannot be easily dissipated by deformation of the tile and is then dissipated by a cohesive failure of the material, i.e. formation of a crack. Such a crack may be a fissure that extends across the entire thickness of the tile or may manifest itself by formation of spall, i.e. chipping, or by the formation of an imprint or crack. In some cases, the spall or crack will form on the underside of the tile.
  • tiles While tiles do not display this sensitivity with respect to humidity changes, the tiles can be cumbersome to install on the floor since they must be fastened to the floor by binder material such as glue or cement and moreover can be heavy because of their high density.
  • the higher density is not desirable because of the weight but also because denser materials tend to more easily transmit noise through their bulk, such as for example treading noise.
  • More porous, and thereby lighter materials such as wood or MDF have better dampening properties and allow for easier installation.
