Definitions

  • a suspended ceiling is a ceiling, which is hung below a main structural ceiling and constitutes a secondary ceiling. It is also referred to as a dropped ceiling.
  • a typical suspended ceiling comprises a frame system suspended on hangers or wires from the main structural ceiling or an overhead structure.
  • Ceiling tiles also known as panels
  • the ceiling tiles thereby form a two-dimensional grid with a number of rows and columns depending on the size of the ceiling with respect to the size of the individual ceiling tiles.
  • Each ceiling tile constitutes a cell in the grid, and the sides of the ceiling tiles form the grid lines of the grid.
  • a plenum space (air-filled space in the structure) may exist between the suspended ceiling and the main structural ceiling. Piping and/or wiring may run above the suspended ceiling in the plenum space.
  • the ceiling tiles are placed in proximity to each other. In this way a suspended ceiling may hide the building infrastructure, including the piping and/or wiring.
  • a suspended ceiling in which access to the plenum space above the suspended ceiling may readily be obtained at any desired location in the grid, is typically referred to as an accessible suspended ceiling construction.

  • the total number of members in the set of ceiling tiles inevitably depends on how many ceiling tiles are needed in order to fill out each cell in the grid, wherein the number of cells in the grid depends on the dimension of the suspended ceiling relative to the dimension of the individual ceiling tiles in the set of ceiling tiles, and the size of a possible gap between ceiling tiles.
  • each ceiling tile in the set of ceiling tiles is substantially rectangular, i.e. each ceiling tile may have a geometry of an irregular polygon, which is approximating the shape of a rectangle or a square.
  • a corner of a ceiling tile may be cut or rounded off, meaning that the ceiling tile may constitute an irregular pentagon with three interior angles being 90° and the remaining two interior angles each being 45°.
