Definitions
- the present invention relates to a method for providing of a transport unit comprising a plurality of tiles, wherein each ceiling tile includes a front surface, a rear surface, at least one side surface and a front surface layer arranged on the front surface.
- the invention further relates to a transport unit comprising at least one stack including a plurality of ceiling tiles and a ceiling tile.
- Suspended ceilings can be installed in many different types of buildings for various reasons, for example to absorb sound, to reflect light, to lower the ceiling height or to conceal installations such as cable arrangements, ventilation equipment, lighting installations and other devices arranged in the space between the suspended ceiling and the ceiling structure of a building.
- Suspended ceilings usually comprise ceiling tiles and a supporting structure.
- the supporting structure normally comprises supporting profiles, which are arranged in a grid defining compartments for individual ceiling tiles or groups of ceiling tiles.
- the ceiling tiles may have sound-absorbing and/or sound-insulation properties in order to improve the acoustic environment of the room.
- the tiles for instance, may be made of a fibre material such as mineral wool and especially glass wool.
- Ceiling tiles are voluminous products, which is a disadvantage during distribution and transport of the ceiling tiles due to cost and due to environmental reasons.
- a typical ceiling tile made of glass wool consists of 95 % of air, the remaining 5 % mainly being fibres of glass wool. Consequently, a large portion of the volume that is transported is in fact air.
- Insulation material for example insulation material made of glass wool and to a certain degree also of rock wool, is often temporarily compressed after manufacture in order to reduce the volume of the product during transport. After being transported, the insulation material is allowed to return to its uncompressed state. However, insulation material is not visible after being mounted to walls or joists. Thereby, no aesthetic requirements are to be considered for the insulation material. If the visual appearance of the insulation material changes during compression is of minor importance. Further, insulation material often lacks a surface layer which could be damaged during compression.
- the aesthetical impression is of large importance for a ceiling tile, and especially the appearance of the front surface of the ceiling tile facing the room.
- the front surface layer is often covered by a surface layer which may be painted. Thereby, the front surface layer is especially delicate. Consequently, the ceiling tile must be handled by care during transport in order to avoid damages. If a ceiling tile, and especially a front surface of the ceiling tile, is damaged during transport, the ceiling tile can not be used due to aesthetical reasons and must be discarded.
- DE 10 2004 022280 A1 discloses a packing unit comprising insulating panels arranged in a stack with front surfaces facing each other.
- a pressure-resistant frame-shaped device encloses sides surfaces of the stack.
- a further object is to reduce costs associated with transport of ceiling tiles and reduce damages of the ceiling tiles originating from transport and handling.
- a method for providing a transport unit comprising a plurality of ceiling tiles made of mineral fibres and a binder, each ceiling tile including a front surface, a rear surface, at least one side surface and a front surface layer arranged on the front surface, the method comprising arranging said plurality of ceiling tiles in a at least one stack including a top ceiling tile, a bottom ceiling tile and at least one intermediate ceiling tile, wherein the front surface layer of each intermediate ceiling tile is facing a front surface layer of an adjacent ceiling tile, compressing said at least one stack to a compressed state, and securing said at least one stack in said compressed state.
- An advantage of the inventive method is that the volume of the stack in its compressed state is reduced compared to the volume of the stack of ceiling tiles in the uncompressed state.
- a higher number of ceiling tiles may be transported and stored per volume unit. Thereby, the cost for transportation and storage of each ceiling tile is reduced. Further, the environmental influence due to transport is reduced since the transport of ceiling tiles becomes more efficient. The volume occupied just by air in a ceiling tile is reduced.
- the load capacity of a lorry is limited by the available volume when transporting ceiling tiles, not by the weight of the ceiling tiles. By compressing the stack of ceiling tiles, the volume of the ceiling tiles is reduced. Due to their low weight, the load capacity is still not limited by the weight of the ceiling tiles.
- each intermediate ceiling tile By arranging the front surface layer of each intermediate ceiling tile such that it is facing the front surface layer of an adjacent ceiling tile, the surface layer remains unaffected by the compression and the risk is significantly reduced that the surface layers get damaged when the ceiling tiles are compressed.
- the surface layers facing each other distribute the pressure uniformly.
- the ceiling tile returns to its original uncompressed state when not longer being affected by a compressing force. Further, the ceiling tile maintains its properties after being compressed and when it has returned to its original uncompressed state. For example, the sound-absorbing properties of the ceiling tile remain unchanged after compression.
- Another advantage associated with the inventive method is that it is possible to offer ceiling tiles having a larger thickness compared to a conventional ceiling tile.
- the sound-absorbing ability of a ceiling tile made of mineral fibre increases in proportion to the thickness of the ceiling tile. Therefore, it may be desirable to offer ceiling tiles having large thickness. Further, the sound-absorbing properties in the low frequency spectrum are also improved by aceiling tile having large thickness.
- the step of arranging said plurality of ceiling tiles in said at least one stack may further include arranging the bottom ceiling tile on a bottom end plate and arranging a top end plate on top of the top ceiling tile.
- the bottom and top end plates distribute the pressure uniformly over the stack and protect the top and bottom ceiling tiles during storage and transport. Further, if a surface layer of the top or end ceiling tiles is abutting the end plate or the bottom end plate, the top or bottom end plate protects the surface layer.
- the method may further comprise arranging said plurality of ceiling tiles in two or more stacks.
- the stacks may be compressed individually or together. If the stacks are compressed together in one step, two or more stacks of ceiling tiles may be arranged adjacent each other between the top and bottom end plate and then be compressed in one step. By collecting ceiling tiles having a relatively small area into several stacks, ceiling tiles having a relatively small area may also be compressed in an efficient way.
- the step of securing said at least one stack in said compressed state may comprise arranging at least one strap surrounding said at least one stack.
- the strap ensures that the stack is maintained in its compressed state during transport and distribution. If top and bottom end plates are used, the strap may also surround the top and bottom end plates. When the stack of ceiling tiles is in the room where they should be mounted, the strap is removed from the stack and the ceiling tiles return to their original uncompressed state.
- the step of securing said at least one stack in said compressed state may comprise arranging a protective film enclosing said at least one stack.
- the protective film ensures that the stack is maintained in its compressed state during transport and distribution. Additionally, the protective film protects the stack of ceiling tiles from moisture or dust. When the stack of ceiling tiles is in the room where they should be mounted, the protective film is removed from the stack and the ceiling tiles return to their original uncompressed state.
- the protective film may be used in combination with a strap surrounding the stack. In this case, the protective film mainly protects the stack from moisture and dust.
- the method may further comprise arranging two or more ceiling tiles in an encapsulation to form a sub-stack, wherein one or more sub-stacks form said at least one stack.
- Forming an encapsulation comprising a number of ceiling tiles facilitates handling of the ceiling tiles both before compression and when the stack returns to its uncompressed state.
- the sub-stacks are compressed in one step such that they together form one stack.
- the present invention is realised by a transport unit comprising at least one stack including a plurality of ceiling tiles made of mineral fibres and a binder, each ceiling tile comprising a front surface, a rear surface, at least one side surface and a front surface layer arranged on the front surface.
- Said at least one stack comprises a top ceiling tile, a bottom ceiling tile and at least one intermediate ceiling tile, wherein the front surface layer of each intermediate ceiling tile is facing a front surface layer of an adjacent ceiling tile, wherein said plurality of ceiling tiles are in a compressed state.
- the inventive transport unit occupies a reduced volume.
- a higher number of ceiling tiles may be stored and transported per volume unit. Thereby, the cost for transport and storage of each ceiling tile is reduced. Further, the environmental influence due to transport is reduced since the transport of ceiling tiles becomes more efficient. The volume occupied just by air in a ceiling tile is reduced.
- the ceiling tiles return to its original uncompressed state when not longer being affected by a compressing force. Further, the ceiling tile maintains its properties after being compressed and when it has returned to its original uncompressed state. For example, the sound-absorbing properties of the ceiling tile remain unchanged after compression.
- each intermediate ceiling tile Due to that the front surface layer of each intermediate ceiling tile is facing a front surface layer of an adjacent ceiling tile, the surface layer remains unaffected by the compression and when the ceiling tiles return to its original uncompressed state. The risk that the surface layer is damaged when the ceiling tiles are compressed is significantly reduced.
- the transport unit makes it possible to offer ceiling tiles having a larger thickness compared to a conventional ceiling tile.
- the sound-absorbing ability of a ceiling tile made of mineral fibre increases in proportion to the thickness of the ceiling tile. Therefore, it may be desirable to offer ceiling tiles having large thickness. Further, the sound-absorbing properties in the low frequency spectrum are also improved by a ceiling tile having large thickness.
- Said at least one stack may further comprise a bottom end plate and a top end plate, wherein the bottom ceiling tile is arranged on the bottom end plate and the top end plate is arranged on top of the top ceiling tile.
- the bottom and top end plates distribute the pressure uniformly over the stack and protect the top and bottom ceiling tiles during storage and transport.
- the transport unit may comprise two or more stacks of ceiling tiles. Thereby, ceiling tiles having a relatively small area may be arranged adjacent each other in stacks and the stacks may then be compressed together. Thereby, a more efficient handling of small ceiling tiles is obtained.
- Two or more ceiling tiles may be arranged in an encapsulation forming a sub-stack, wherein one or more sub-stacks form said at least one stack.
- the encapsulation comprising a number of ceiling tiles facilitates handling of the ceiling tiles both before compression and after compression when the stack returns to its original uncompressed state.
- the bottom end plate may comprise a pallet.
- the transport unit may be operated by fork-lift truck.
- the present invention is realised by a ceiling tile made of mineral fibres and a binder, comprising a front surface, a rear surface, at least one side surface and a front surface layer arranged on the front surface.
- the mineral fibres are homogenously distributed and orientated in a plane parallel with the front surface.
- the front surface layer is air permeable and comprises a layer of paint, and said ceiling tile being elastically compressible.
- the ceiling tile being elastically compressible is meant that the ceiling tile returns to its original uncompressed state when not being subjected to external forces affecting the ceiling tile.
- the ceiling tile maintains its properties when being compressed and after it has returned to its original thickness. After being compressed, the ceiling tile returns to its original thickness, or at least to a thickness being at least 90% of its original thickness.
- the ceiling tile may be elastically compressible to a compressed thickness corresponding to at least 1/3, preferably 1/5, of an original thickness of said ceiling tile. Thereby, the volume to be transported may be reduced to 1/5 of the original volume.
- a ceiling tile being elastically compressible is that it is possible to compress the ceiling tile. Thereby, the volume of the ceiling tile in its compressed state is reduced. The ceiling tile may be kept in its compressed state during transport and storage.
- the reduced volume is favourable due to that a higher number of ceiling tiles may be stored per volume unit. Consequently, the cost for transportation and storage of each ceiling tile is reduced. Further, the environmental influence due to transportation is reduced since the transport of ceiling tiles becomes more efficient. The volume occupied just by air in a ceiling tile is reduced.
- a ceiling tile having the above defined properties returns to its original uncompressed state when not longer being affected by a compressing force. Further, the ceiling tile maintains its properties after being compressed and when it has returned to its original uncompressed state. For example, the sound-absorbing properties of the ceiling tile remain unchanged after compression.
- ceiling tiles having a larger thickness compared to a conventional ceiling tile.
- the sound-absorbing ability of a ceiling tile made of mineral fibre increases in proportion to the thickness of the ceiling tile. Therefore, it may be desirable to offer ceiling tiles having large thickness. Further, the sound-absorbing properties in the low frequency spectrum are also improved by a ceiling tile having large thickness.
- the inventive ceiling tile makes it possible to compress a ceiling tile having a front surface layer without damaging the front surface layer.
- the front surface layer remains unaffected when the ceiling tile returns to its original uncompressed state.
- the front surface layer may fulfil fire safety requirements according to Euroclass A2-s1, d0.
- Euroclass A2-s1, d0 is a class within the reaction to fire classification system for linings and material in Europe according to the classification standard EN 13501-1.
- A2 denotes the main level
- s1 denotes the class for smoke production
- d0 denotes the class for occurrence of flaming droplets/particles.
- the sound-absorbing ceiling tile may further comprise a rear surface layer arranged on the rear surface.
- the rear surface layer improves the rear surface of the ceiling tile and the visual appearance.
- the sound-absorbing ceiling tile may further comprise a side surface layer arranged on said at least one side surface. Since the side surface in some arrangements is visible for a person in the room when the ceiling tile has been mounted in a suspension system, it is desirable to provide the side surface with a surface layer, which may include a layer of paint.
- Said at least one side surface may have an inclined surface portion.
- the side surface may be provided with an inclined portion.
- the side surface is provided with a surface layer, it is advantageous to arrange an inclined surface portion on the side surface.
- the inclined surface portion facilitates compressing of the ceiling tile and reduces the risk that the side surface layer is damaged when the ceiling tile is compressed.
- Said at least one side surface may comprise a cut-out.
- the side surface may be provided with a cut-out.
- the side surface is provided with a surface layer, it is advantageous to arrange a cut-out on the side surface. The cut-out facilitates compressing of the ceiling tile and reduces the risk that the side surface layer is damaged when the ceiling tile is compressed.

- a side surface layer 11, 12 may be arranged on said at least one side surface 5, 6.
- the side surface layer 11, 12 comprise a layer of paint. Having a painted side surface layer 11, 12 may be desirable in an arrangement wherein the side surface 5, 6 is visible when the ceiling tile 1 is mounted to a suspension system.
- the side surface layer 11, 12 may be painted on the side surface 5, 6 or may be applied in accordance with the method disclosed in EP 2 027 990 .
- the surface layers may all be susceptible to cracking, i.e. being sensitive to impact and easily damaged.
- the ceiling tile 1 is elastically compressible. With elastically compressible is meant that the ceiling tile 1 resumes its original uncompressed state when not being subjected to external forces affecting the ceiling tile 1 to be in its compressed state.
- the ceiling tile 1 maintains its properties, for example its sound-absorbing properties, when being compressed and after it has returned to its original thickness. After being compressed, the ceiling tile 1 returns to its original thickness, or at least to a thickness being 90% of its original thickness.
- the ceiling tile 1 is in a compressed state.
- the ceiling tile 1 has been compressed to a density of approximately 100 kg/m 3 , regardless the original density of the ceiling tile 1.
- the ceiling tile 1 may be compressed to a compressed thickness being at least 1/3, preferably 1/5, of its original thickness. Thereby, the volume of each ceiling tile 1 which is to be transported is reduced to 1/5 of the original volume.
- a ceiling tile 1 having an original density of 30 kg/m 3 can be compressed to a compressed thickness of 1/3 of the original thickness.
- the ceiling tile 1 has been compressed in a direction being perpendicular to the plane of the front surface and rear surface 3, 4. A uniform pressure has been applied in order to obtain a uniform compression of the ceiling tile 1. Any surface layer 10, 13 arranged on the front and/or rear surface 3, 4 remains planar in the compressed state of the ceiling tile 1 and is therefore not affected or damaged by the compression.
- the homogenously distribution and the orientation of the mineral fibres in a direction planar to the front and rear surfaces 3, 4 allows a uniform compression of the ceiling tile 1 and that any surface layer 10, 13 does not get damaged during compression.
- a side surface layer 11, 12 is arranged to one or more of the at least one side surface 5, 6, 7, 8, the side surface may be modified in order to facilitate compression of the ceiling tile 1 without damaging the side surface layer 11, 12.
- the side surfaces 5, 6 are inclined, as visible in the cross section in figure 3b .
- only a portion of the side surfaces 5, 6 may be inclined.
- the ceiling tile 1 in figure 3a is shown when being compressed.
- the inclined side surface 5, 6 facilitates compression of ceiling tile 1 without affecting the side surface layer 11, 12 such that damages on the side surface layer 11, 12 may be avoided.
- the inclination angle of the inclined side surface 5, 6 increases, but the surfaces 5, 6 on which the side surface layer 11, 12 are applied to are not affected by the compression.
- the side surfaces 5, 6 of the ceiling tile 1 having a side surface layer 11, 12 is provided with a cut-out 20, 21.
- the cut-out 20, 21 is V-shaped and extends towards the centre of the ceiling tile 1.
- the cut-out may have another shape or that more than one cut-out is provided in the side surface of the ceiling tile 1.
- the side surface may have straight portions combined with cut-outs.
- the cut-out 20, 21 divides the side surface 5, 6 into a first side surface portion and a second side surface portion.
- the V-shaped cut-out 20, 21 functions as a hinge when the ceiling tile 1 is compressed.
- the side surface layer 11, 12 is adhered to the inclined portions of the cut-out 20, 21.
- a ceiling tile 1 having side surfaces layers 11, 12 is disclosed.
- the side surfaces 5, 6, 7, 8 are provided with a first and second inclined surface portions 5a, 6b, 8a, 8b, as visible in figure 5b .
- the inclined surface portions form an edge functioning as a hinge during compression.
- the surface portions 5a, 5b, 8a, 8b are displaced towards each other and the angle between the two surface portions is reduced as shown in figures 5c-d .
- the side surface layer 11, 12 is not affected by the compression and the risk for damages on the side surface layer 11, 12 is reduced.
- the side surface layer 11, 12 may be flexible.
- the ceiling tile 1 may have a laminated structure, which is shown in figures 6a-b .
- the laminar structure comprises a first tile body portion 2a adapted to face the room and a second tile body portion 2b adapted to face the ceiling structure.
- the first and the second tile body portions 2a, 2b are adhered to each other to form one ceiling tile 1.
- the front surface 4 is provided with a front surface layer 10 and the rear surface 3 is provided with a rear surface layer 13.
- the first and the second tile body portions 2a, 2b may have different properties.
- the second tile body portion 2b may have a lower density and larger thickness compared to the first tile body portion 2a.
- the second tile body portion 2b may be compressed to a larger extent than the first tile body portion 2a, which is shown in figure 6b .
- the second tile body portion 2b improves the sound-absorbing properties of the ceiling tiles 1, especially in the low frequency spectrum. Since the sound-absorbing capacity for a mineral fibre material increases with the thickness of the ceiling tile 1 but does not vary largely with the density, a ceiling tile 1 having a larger thickness is favourable. The possibility to compress the ceiling tile 1 offers a possibility to provide such a thicker ceiling tile 1 in a rational manner.
- ceiling tiles 1 having an edge including a complicated profile are usually made of a tile body 2 having a comparably high density.
- a high density is often required in order to machine the desired profile. Due to the high density, the ceiling tile may not be compressed to a desirable extent.
- the ceiling tile 1 may have a laminar structure, which is shown in figures 7a-b to which reference now is made.
- the laminar structure comprises a first ceiling tile body portion 2a adapted to face the room which have a high density.
- the profile of the side surfaces 5, 6 is machined in the first tile body portion 2a.
- a second tile body portion 2b is adhered to the first tile body portion 2a.
- the second tile body portion 2b has a lower density compared to the first tile body portion 2a, thus being compressible to a higher extent. Additionally, the thickness of the first body portion 2a may be less than the thickness of the second tile body portion 2b. Thereby, the total volume of the ceiling tile 1 may still be reduced when the ceiling tile 1 is compressed. In figure 7b the ceiling tile 1 having the laminar structure is shown in its compressed state, wherein the second tile body portion 2b is compressed to a higher extent compared to the first tile body portion 2a.
- the ceiling tiles 1 are of the above described type comprising mineral fibre and a binder.
