Definitions

  • This invention relates to a building structure, notably a fire rated door, and an insulation panel therefore.
  • Mineral wool insulation panels are commonly used within fire rated doors and can contribute significantly to the fire resistance of the door.
  • the use of high density, high thicknesses mineral wool insulation panels enables desired levels of fire resistance to be achieved.
  • Commercial panels generally have a homogenous mineral wool structure throughout their entire volume but the inclusion of additional elements has been proposed.
  • EP1347144 and EP1347145 discloses the inclusion of fire-protection rods, for example of aluminium hydroxide or magnesium hydroxide, in a middle layer of a mineral wool insulating plate of a fire-protection door.
  • the building structure of EP1347145A2 discloses all the features of the preamble of claim 1.
  • insulation panels for example for fire rated doors, can be improved, notably to retain desired levels of fire resistance whilst improving one or more other properties.
  • the present invention provides a building structure as defined in claim 1. Additional aspects of the invention are defined in independent claims. The dependent claims define preferred and/or alternative embodiments.
  • the present invention provides an improved building structure, notably an improved door, which combines a desired combination of fire resistance and acoustic attenuation in a simple structure. Furthermore, such properties may be obtained using an insulation panel of lower mass; the lower mass facilitates handling and efficient use of materials.
  • the present invention provides a building structure comprising a single piece mineral wool insulation panel arranged in a cavity between first and second structural plates, for example the cavity of a door.
  • the single piece mineral wool insulation panel has a first, planar major surface and a second planar major surface, the first and second major surface of the mineral wool insulation panel preferably being parallel to each other.
  • the first major surface of the mineral wool insulation panel is preferably arranged adjacent to a planar, cavity side major surface of the first structural plate; the second major surface of the mineral wool insulation panel is preferably arranged adjacent to a planar, cavity side major surface of the second structural plate. Furthermore, the mineral wool insulation panel comprises a plurality of acoustic cavities positioned between its first and second major surfaces.
  • first and second structural plates may comprise a sheet metal plate, for example a steel plate or an aluminium plate, notably having a thickness which is ⁇ 0.5 mm or ⁇ 1 mm and/or ⁇ 5 mm or ⁇ 3 mm.
  • the first and second structural plates may be structural plates of a fire door, for example sheet metal plates of a fire door.
  • the cavity side major surfaces of the first and second structural plates are preferably parallel.
  • the cavity side major surfaces of the first structural plate is preferably arranged in substantially continuous contact with a first major surface of the insulation panel; likewise, the cavity side major surfaces of the second structural plate is preferably arranged in substantially continuous contact with a second major surface of the insulation panel.
  • Arranging for one or both planar surfaces of the mineral wool insulation panel to be in continuous contact with its associated cavity side major surface of the structural plate facilitates assembly, for example by facilitating gluing of the mineral wool insulation panel to one or both cavity side surfaces of the structural plates.
  • the combination of a planar surface of the mineral wool insulation panel assembled against and/or in contact with a planar surface of the structural plate may also help to avoid the risk on a non-homogeneous visual appearance at the external side of, notably sheet metal, structural plates.
  • the first and/or second structural plates may comprise or consist of wooden plates or panels or plastics plates or panels which define an internal door cavity in which the insulation panel is arranged.
  • Each wooden or plastics panel or plate may have a thickness ⁇ 2 mm, notably ⁇ 2.5 mm or ⁇ 3 mm and/or ⁇ 8 mm notably ⁇ 5 mm or ⁇ 4.5 mm.
  • the wooden panels or plates may be of chipboard or medium density fibre board (MDF) or high density fibre board (HDF) and may comprise a veneer.
  • MDF medium density fibre board
  • HDF high density fibre board
  • the building structure may be a fire rated door, for example, a door meeting a Ei30, Ei60, Ei90 or Ei120 fire class.
  • the door may have a door leaf thickness ⁇ 30 mm, notably ⁇ 35 mm or ⁇ 40 mm and/or ⁇ 100 mm notably ⁇ 85 mm or ⁇ 70 mm.
  • the door leaf weight in kg/m 2 may be ⁇ 10, notably ⁇ 15 or ⁇ 20 and/or ⁇ 100 notably ⁇ 70 or ⁇ 40.
  • the building structure may be a sandwich panel.
  • the insulation panel is a single piece insulation panel.
  • the term single piece insulation panel means that the mineral wool fibres of the insulation panel are all held together to form a mineral wool panel that may be handled as a single piece as opposed to a plurality of non-attached individual pieces.
  • the provision of a single piece mineral wool insulation panel having a height of, for example at least 160 cm and a width of, for example at least 60cm allows the panel to be used without requiring additional panels to fill the cavity of, for example a fire rated door.
  • the building structure particularly in the case of a door or a sandwich panel, preferably comprises a single mineral wool insulation panel. Handling and assembling a single panel is easier and more efficient than dealing with multiple different panels.
  • the panel may be substantially rectangular; it may be provided with preformed cuts and/or cut-outs to facilitate its assembly in a door cavity.
  • the panel may be provided in the form of a panel in which the acoustic cavities have been cut out and removed from a single starting panel.
  • the panel may be provided as a single piece insulation panel formed from assembly of a plurality of individual pieces of mineral wool insulation.

  • the width of the mineral wool insulation panel may be ⁇ 60 cm, optionally ⁇ 70 cm or ⁇ 80 cm and/or ⁇ 150 cm, optionally ⁇ 120 cm or ⁇ 100 cm.
  • Reference to the surfaces of the mineral wool insulation panel being planar as used herein means that the surface defined by the combination of all of the individual fibre at the surface of the mineral wool panel is planar, notwithstanding interstices between individual fibres as the surface
  • the acoustic cavities are air cavities, that is to say, cavities that contain only air and any materials present in atmospheric air, for example water vapour.
  • the term "acoustic cavity” as used herein means a cavity in the mineral wool insulation panel which provides a reduction in the sound that passes through the mineral wool insulation panel from its first to its second major surface structure, notably when the mineral wool insulation is sandwiched between the first and second structural plates in the building structure.

  • the acoustic cavities may be positioned equidistantly between the first and second major surfaces. They may form a discontinuous layer of cavities within the mineral wool structure.
  • the acoustic cavities may have a thickness which is ⁇ 2mm, ⁇ 5mm, ⁇ 10 mm, ⁇ 15 mm, or ⁇ 20 mm, and/or ⁇ 60 mm, ⁇ 50 mm or ⁇ 40 mm.

  • the term oroiected surface area means the maximum surface area of the acoustic cavities at a plane which is parallel to the plane of the first major surface of the mineral wool insulation panel.
  • the acoustic cavities may provide the mineral wool insulation pane and/or the building structure with an improved level of sound reduction performance with respect to that obtained using a comparable mineral wool insulation panel without the acoustic cavities, notably a level of sound reduction performance that is better by ⁇ 2 dB, ⁇ 3 dB, ⁇ 4 dB or ⁇ 5 dB. Any such comparison should be made with a mineral wool insulation panel having comparable, notably identical, structural features including, for example, dimensions and density, in a test simulating the intended use of the mineral wool insulation panel and/or the building structure.
