Definitions

  • the present invention relates to an insulating construction panel for the construction of a building.
  • Traditional building methods for walls in buildings generally consist of a timber frame structure filled with insulation such as mineral wool.
  • This timber frame structure extends through the entire wall, from its inner side to its outer side.
  • the wall is assembled on the building site, which means that damp enters easily into the wall construction, something which strongly impairs the insulating capacity of the wall and increases the risk of damp and mould damage in the wall.
  • the method is not suitable for the construction of passive houses, where a higher insulating capacity in the wall is required in order to meet the criteria for passive houses.
  • a traditional building method of this kind a very thick wall construction is required in order to meet these criteria, with thicker timber frame structure and more mineral wool.
  • a sandwich panel consists of two face sheets and a core layer arranged between the two face sheets.
  • the face sheets are made of a stable material in order to support the construction.
  • the function of the core layer is mainly to contribute insulating properties and to have a load-transmitting function between the two face sheets.
  • sandwich panels in wall construction does however change the building method for both the inner side and the outer side of a wall in a building. This can be difficult to get the building trade to accept, since contractors such as electricians, carpenters, masons, etc. are not used to working with such types of material.
  • sandwich panels having wooden face sheets are generally used. Wooden face sheets can give rise, for example, to mould damage in the panel.
  • an insulating construction panel for the construction of a building is provided, the construction panel is prefabricated in a plant, prior to use of the construction panel in the construction of a building, comprising a first face sheet and a second face sheet, adapted to lend stability to the construction panel.
  • the construction panel further comprises an insulating core layer arranged between the first and the second face sheet, the first face sheet, the second face sheet and the core layer together forms a sandwich-type construction panel.
  • the construction panel also has a frame structure fitted to the first face sheet, so that the first face sheet is placed between the frame structure and the core layer.
  • the first and the second face sheet consists of magnesium oxide and the core layer consists of a foamed plastics material.
  • the frame structure When the construction panel is fitted as a wall in the construction of a building, the frame structure may be directed towards the inner side of the wall, i.e. the side of the wall which is directed towards the inner side of the building. A wall structure which resembles traditional building methods for the inner sides of walls may thus be realized.
  • the frame structure may be filled with further insulation, in the same way as in a traditional building method. Persons constructing the building may thus feel familiar with the building method and construct the inner side of the wall as previously.
  • the frame structure In the finishing of the inner side of the wall, the frame structure may be covered by plasterboards.
  • the core layer may have both an insulating function and a load-transmitting function to the face sheets.
  • the principal object of the core layer to have an insulating function may thus be met.
  • a plastics material of this kind may have the advantage that it is not organic, and thus further prevents mould growth, for example, in the panel. Moreover, such a material may not be water-permeable, which may give less risk of damp damage and greater insulating capacity.
  • the load-transmitting function may contribute to the stability of the construction panel. Furthermore, such a construction panel may provide adequate insulating capacity with a thinner wall thickness than with a traditional building method. A building may thus gain larger internal dimensions, with maintained external dimensions, in relation to a traditional building method.
  • a construction panel according to the invention further has the advantage that it is prefabricated, which means that little time may be required at the building site for assembly and installation. This also may make the construction of the building cost-effective. Furthermore, the fact that the construction panel is prefabricated and that no organic materials are used against the outer side of the wall may mean that the wall construction effectively acts both as a climate shield and as a moisture barrier. Since cold bridges out towards the outer side of the wall may be avoided, it may make the wall construction more energy-efficient.
  • a face sheet which is made of a fireproof material By having a face sheet which is made of a fireproof material, a face sheet which not only stabilizes the construction panel but also has a fire safety function may be realized. There may be a considerable safety benefit from a wall construction in a building which also has advantages in terms of fire safety. Furthermore, a highly alkaline, yet inorganic material, magnesium oxide, is used as the fireproof material in the face sheets and can thus prevent the possible incipient growth of mould, for example, in the construction in the event of damp formation. This may be in contrast to a situation in which, for example, wood is used in the face sheets.
  • the sandwich structure there is provided a construction panel which is stable and thin, yet has very good insulating capacity may thus be realized. The same insulating capacity with a wall made from traditional building methods may require a much thicker wall, while, at the same time, such a wall may be less proof against damp damage.
  • the panel being prefabricated in a plant it is made possible that the construction panel is produced in a protected environment, without risk of the construction panel being exposed to high moisture contents.
  • the frame structure may be a timber frame structure.
  • the inner side of a wall may thus be constructed with the timber frame structure, which then resembles a timber-framed wall constructed with a traditional building method.
  • a base for plaster against an outer facade of a building on the second face sheet may be arranged a base for plaster against an outer facade of a building.
  • a base for plaster against an outer facade of a building there may thus be no need for further layers of the construction panel against the outer facade of the building when the construction panel may be fitted during construction of the building, but rather plaster may be applied directly to the construction panel.
  • the need for an air gap against the outer side of the wall may thus be avoided. Since the plaster base may be pre-mounted on the construction panel, the risk of damp damage against the outer side of the wall may also be eliminated, as the construction panel may be produced in a protected environment.
  • an aluminium foil on at least one of the first and the second face sheet may be arranged an aluminium foil.
  • an aluminium foil arranged on a face sheet radiation heat may be reflected by the construction panel.
  • an aluminium foil arranged on the first face sheet preferably on the side which is directed away from the core layer, radiation heat from within a building, when the construction panel is fitted as a wall in a building, may be reflected back into the building.
  • an aluminium foil arranged on that side of the second face sheet which is directed away from the core layer radiation heat from outside, against a building in which the construction panel is fitted as a wall, may be reflected back out, away from the building.
  • the construction panel thus gains further insulating capacity.
  • the frame structure may be arranged to define a space intended for filling with an insulating material.
  • the insulating material may be mineral wool, for example.
  • Fig. 1 shows a construction panel 1 according to one embodiment of the invention.
  • a first face sheet 10 and a second face sheet 11 are arranged on one side each of a core layer 12. These three parts 10, 11, 12 together form a so-called sandwich panel.
  • the face sheets 10, 11 are made of magnesium oxide. This gives the face sheets 10, 11 stable and fireproofing properties.
  • the core layer 12 is made of a foamed plastics material, for example polyurethane foam or an EPS plastic (Expanded Polystyrene).
  • the function of the core layer 12 is to contribute to the strength and insulating capacity of the construction panel 1.
  • the core layer 12 has a function of transmitting load to the face sheets 10, 11.
  • the frame structure is preferably a timber frame structure 13.
  • the frame structure can in other embodiments be made of other materials such as steel or aluminium.
  • the first face sheet 10 is thus placed between the core layer 12 and the timber frame structure 13.
  • the timber frame structure 13 is designed to resemble a timber frame construction according to a traditional building construction of a wall in a building. Contractors and others working on a building site on the construction of a building may thus feel at home with how it is used to look when, for example, the inner side of the wall of the building is to be finished. There is also less risk of handling errors on the building site, since the construction panel 1 is easy to fit.
  • the difference compared with a wall erected according to a traditional building method is then, instead, that a wall erected with construction panels 1 according to the embodiment has a more effective insulating capacity and can be erected in shorter time.
  • the timber frame construction 13 is a part of the inner side of the wall in the building.
  • a plaster base 14 is arranged in the construction panel 1.
  • the plaster base is fixed to that side of the second face sheet 11 which is directed away from the core layer 12.
  • the plaster base 14 can consist of a sheet of an EPS plastic or the like.
  • the object of the plaster base 14 is, following the fitting of construction panels 1 in the construction of a building, to act as a base for plaster constituting the outer facade of the building.
  • a construction panel 1 having such a plaster base 14 eliminates the need for air gaps against the outer side of the wall construction of the building.
  • one or both face sheets 10, 11 can have one side covered by an aluminium foil.
  • Fig. 2 shows schematically an erected construction panel 1 for a wall in a building.
  • the construction panel 1 is placed on a building foundation 40 so that the whole of the construction panel 1, apart from the plaster base 14, is located on the building foundation 40.
  • a plaster cladding 20 for constituting the outer facade of the building.
  • a plasterboard 30 for constituting a part of the inner side of the wall of the building.
  • a space is defined by the timber frame structure filled with mineral wool 31. In this way, the inner side of the wall of the building can be finished with just the supply of mineral wool 31 and plasterboard 30 following the erection of the construction panel 1.
  • a considerable time saving is thereby achieved compared with the erection of a wall in a building according to a traditional building method.
  • a section wall for a building according to a traditional frame construction with mineral wool is estimated to take about 2.5 - 3 hours per square metre to erect.
  • a section wall having construction panels 1 according to the invention is estimated to take about 0.2 hours per square metre to erect.
  • the sandwich part 10, 11, 12 of the construction panel 1 is around 14 cm thick.
  • a U-value of 0.1 can be attained with a sandwich part thickness of around 14 cm.
  • a U-value indicates the thermal conductivity of a material layer. The value is quoted in Watts per square metre and Kelvin. The better the insulating capacity, the lower the U-value.
  • the timber frame structure 13 is around 10 cm thick, and the plaster base 14 around 5 cm thick. This makes the thickness of the construction panel 1 around 29 cm.
  • a wall In the construction of a building, a wall can be constructed with a total thickness of around 30-31 cm, of which the construction panel 1 constitutes around 29 cm, and plaster 20 applied to the plaster base 14 and a plasterboard 30 arranged on the timber frame structure 13 account for the remaining thickness.
  • plaster 20 applied to the plaster base 14 and a plasterboard 30 arranged on the timber frame structure 13 account for the remaining thickness.
  • Such a construction meets the criteria for passive houses and acts effectively as a climate shield and moisture barrier.
  • Fig. 3 shows a construction panel 2 erected in a multistorey building.
  • the floor joists 50 for the upper storey are in this case suspended from timber frame structure 13 in the construction panel 2. Outside of this suspension, the face sheets 10, 11, the core layer 12 and the plaster base 14 protect against the formation of any cold bridges.
  • a construction panel 2 which acts as a climate shield and moisture barrier even in a multistorey construction is thus attained.
