Definitions
- the invention concerns a mineral fibre board of relatively high density for heat, sound or fire insulation.
- the board has at least two resilient minor side surfaces in order to prevent any small gaps in the joints between two adja ⁇ cent boards.
- the purpose of the invention is to improve the effect of the insu ⁇ lation layer and thereby either reducing the heat loss to a minimum in order to comply with new standards for low energy consumption buildings or to im ⁇ prove the fire properties of a fire protection insulation layer on e.g. steel con- structions.
- the invention also concerns a method for producing the mineral fibre board and a method for installing the boards.
- higher densities of the insulation boards are used compared to standard building insulation, e.g. insulation between the rafters. This higher density gives a higher strength and mechanical stability of the insulation board, and it is prevented that the insulation could buckle out from the sur ⁇ face to which it is attached in the area between the fasteners.
- the first is to have more than one layer of insulation installed so that the spaces between the boards in the e.g. two layers of boards do not over ⁇ lap. This method will make the insulation more time consuming to install.
- the second method is to give the edges of the boards a shape or profile which will prevent an open access to the insulated surface along a straight line per ⁇ pendicular to the surface against which the insulation is placed. This shape or profile could be groove and tongue like. This method will make each insu ⁇ lation board more expensive to produce, primarily because the production will have a higher waste of mineral wool.
- the present invention has solved the above mentioned problems by making at least two of the minor side surfaces on a high density mineral fibre insula ⁇ tion board resilient, i.e. more elastically compressible than the rest of the board. This has not been done before for mineral fibre insulation densities considerably higher than densities used for standard building insulation, e.g. between rafter insulation below the roof of a building. It has furthermore been found that it is possible to manufacture such boards.
- minor side sur ⁇ faces are understood, which are easily compressible by hand, and which are elastically compressible in such a way that removing the compression will make the minor side surface of the board regain substantially its original di ⁇ mension, however minor deviations from its original dimension should be ex ⁇ pected.
- the rest of the board away from the resilient surfaces has a higher stiffness.
- the stiffness may be defined according to EN826.
- the whole minor surface should be substantially equally resilient.
- the method is to let one board or a stack of boards pass two zones i.e. two compression stations with rollers on one side of the conveyor and a smooth conveyor sur- face on the opposite side of the rollers for holding the stack of boards in posi ⁇ tion.
- This support will pre ⁇ vent the board from bending due to the compression force. Any bending of the board during the compression will mean that the resilient zone will not get the specified depth. Furthermore, bending may cause de-lamination of the board, especially when the board is a dual density board.
- the inventive mineral fibre insulation board will have the advantage that the resilient minor side surfaces will compensate for the tolerances of the boards. These tolerances are often in the millimetre range, and are present in both the width and length of the board and in the angles of the board resulting in deviations from a purely rectangular box shape. The tolerances are due to the fast cutting out the boards from the mineral fibre web moving on the con ⁇ veyor line. The tolerances will often be in the range up to 5 mm and some- times even up to 8 mm. This means in practice that there might be difference in the width or length of a board of 5 mm from one end to the other in the width or length direction. These tolerances will lead to small gaps between a numbers of the boards on a facade when traditional boards without resilient minor side surfaces are used. The resilient minor side surfaces will make it possible to press the boards together by hand when installing the boards and by compressing the minor side surfaces slightly the elastically compressible zone will fill out any gaps between the boards.
- the resilient zone do not need to extend for a dis- tance into the insulation board measured perpendicularly to the minor surface of no more than 50 mm, preferably no more than 30, and even more prefera- bly no more than 20 mm, along the entire length, or the major length, of said minor surface.
- the inventive mineral fibre insulation board will be especially advantages when fasteners placed between two neighbouring boards are applied. It will be easy to push the two boards closely together so that the elastically com ⁇ pressible zone will close any gap around the fastener and thereby avoiding that the fastener may create a small air gap between the two insulation boards, which otherwise often would be the case, because the boards due to the fastener cannot be pushed closely together. The same will be the case when fasteners for the external wall cladding are placed between the insula ⁇ tion boards.
- a dual density insulation board will have two closely connected layers of mineral fibres where the density of the one layer is different from the density of the other. Typically the layer with the highest density will make up the smallest fraction of the total thickness of the insulation board. This would be beneficial in the case of building fa ⁇ ade insulation where a higher density of the outer layer of the insulation would make the insulation layer more resis ⁇ tant to mechanical damages during installation of the outer visible surface layer on the facade. If the outer layer is a render layer applied directly to the surface of the mineral fibre insulation layer a high insulation density in the surface will be preferable.
- mineral fibre insulation comprises a large number of individual fibres having different lengths and diameters.
- a binder e.g. in the form of drops of a thermosetting resin, is added to the mineral fibres. Said binder is cured in a curing oven and will thereafter make the fibres stick to each other at the points where the fibres are in contact with each other.
- a method for making one or more minor side surface surfaces of this mineral fibre insulation board elastically compressible is to compress one or more rollers a distance into the minor side surface or edge surface.
- the diameter of the compression applying roller(s) must be relatively small in order to con ⁇ centrate the compression forces in the desired region.
- the diameter is usu- ally 200 - 500 mm.
- the rollers are pressed a distance of 15 - 50 mm, pref- erably 20 - 30 mm into the edge.
- the numbers of rollers would often be 1 - 7, preferably 2-4.
- the first roller will be pressed a shorter distance into the board than the following rollers.
- the distance by which the roller is pressed into the board from roller to roller also when several rollers are applied.
- the distances will be dependent on the density of the board and if it is a dual density or mono density board.
- the strength and the mechanical stability of the mineral fibre board are not only related to the density of the board but also to the binder content. There ⁇ fore, the elasticity of the edge portions should be seen in relation to the over ⁇ all elasticity of the board.
- the binder content of the board according to the invention is at least 2 %, preferably at least 3 %, and even more preferably at least 4 %. When the boards are intended for fire protection purposes the binder content may be down to 0.8 %, preferably down to 1.4 %.
- the fibre orientation will usually be substantially parallel to the major surfaces of the board when boards of one mono density are applied. If the board is a dual density the fibre orientation will be more complex.
- the invention concerns a mineral fibre insulation board for heat, sound or fire insulation comprising mineral fibres and a binder, said board having two ma ⁇ jor surfaces being approximately parallel to each other, and having four minor surfaces forming the side surfaces of the insulation board, where at least two of the minor surfaces each represents a surface of a resilient zone of the board covering substantially the surface of the resilient zone which zone goes a distance from the minor surface into the insulation board, where said resilient zone having sufficient elastic properties to prevent substantially any gaps to neighbouring boards when compressed against these during installa ⁇ tion and in that the board has a density being sufficiently high to apply the board for purposes such as external wall insulation or fire insulation of steel constructions.
- resilient is basically meant that it is easily compressed by hands during installation.
- the inner portion of the board away from any of the surfaces is substantially stiff and not resilient.
- the density of the board is more than 60 kg/m 3 , preferably at least 70 kg/m 3 , and even more preferably at least 80 kg/m 3 .
- the resilient zone along at least two of the edges i.e. the minor surfaces
- the resilient zone extending for a distance into the insula ⁇ tion board measured perpendicularly to said minor surface of no more than 50 mm, preferably no more than 30, and even more preferably no more than 20 mm, along the entire length, or the major length, of said minor surface.
- the insulation board may comprise at least two different layers of mineral fibre having different densities. This is also known as a dual density board.
- two minor surfaces with a resilient zone have one corner in common, i.e. this is two minor surfaces being perpendicu ⁇ lar to each other.
- the invention concerns an insulating construction comprising an inner surface against which one layer of insulation boards is installed and fastened by fastening means and an outer covering layer characterised in that the insulation layer comprises one layer of the insulation boards de- scribed above.
- the insulation boards for this construction may be fastened by mechanical means.
- the fastening means may be placed along parts of the edges of the insulation boards.
- the outer covering layer for the construction is usually selected from the group of: metal foil, render, wood, eternit, com- pressed mineral fibre boards, paint or fleece, e.g. made from glass fibres. Other outer coverings may also be applied.
- the inner surface of this construction is often the fagade of a building or the inner sur ⁇ face is a steel construction, e.g. a load carrying steel construction which needs to be fire protected.
- the invention also concerns a method for producing a mineral fibre insulation board for heat, sound or fire insulation comprising mineral fibres and a binder, said board having two major surfaces being approximately parallel to each other, and having four minor surfaces (edges) where at least two minor surfaces (edges) represents a surface of a resilient zone of the board, this resilient zone goes a distance into the board where said mineral fibre insula ⁇ tion having a density of at least 60 kg/m 3 and the method comprises the fol ⁇ lowing steps: 1 ) Mixing mineral fibres and a binder into a web 2) Curing the binder 3) Providing at least two of the four minor surfaces of the board with a resilient zone by a mechanical treatment comprising that the boards passes a zone where rollers compresses the minor surface to make the board more resilient in that zone.
- the invention concerns a method of installing mineral fibre insulation for heat, sound or fire insulation where the boards have at least two resilient edges and said boards have a density of at least 60 kg/m 3 and in that any gaps between the boards are avoided by pressing the boards together so that said resilient edges are compressed by hand and therefore closes any gaps between two boards and in that only one layer of insulation boards are installed on the surface.
- the mineral fibre insulation board is made for being applied for heat insulation of building facades.
- the density of the board is approximately 60 kg/m 3 , preferably more than 60 kg/m 3 , and even more preferably more than 70 kg/m 3 .
- the board has a length of 400 - 1000 mm, preferably 500 - 700 mm and even more preferably approximately 600 mm.
- the board has a height of 600 - 2000 mm, preferably 800 - 1500 mm and even more preferably 1000 - 1200 mm.
- the board has a thickness of 100 - 400 mm, preferably 150 - 300 mm and even more preferably ap- proximately 200 mm.
- the board has two edges which are made resilient into a depth of 5 - 15 mm, preferably 8 - 13 mm and even more preferably 10 - 12 mm. These two resilient edges have one corner in common.
- a dual density mineral fibre insula- tion board is used.
- This board will have an average density and all dimen ⁇ sions as described in the previous embodiment. But this board will have a top layer where the density is higher than in the lower layer of the board.
- the top layer would typically have a thickness of 8 - 20 mm, preferably 10 - 15 mm.
- the density of the top layer will be a factor of 1.5 - 3, preferably a factor of 2 higher than the density of the lower layer.
- the mineral fibre insulation board is made for being applied for fire insulation of metal constructions, e.g. steel or aluminium constructions, such as the load-bearing steel constructions in buildings or ship bulkheads and decks on ships e.g. on the lower side of decks, including the girders.
- metal constructions e.g. steel or aluminium constructions, such as the load-bearing steel constructions in buildings or ship bulkheads and decks on ships e.g. on the lower side of decks, including the girders.
- a fire insulation board according to the invention will have at least two resil ⁇ ient edges giving an elastically compressible zone along a region of the edge, which due to its elasticity will regain its original shape after compres- sion.
- the compression of this zone means that the risk of gaps occurring dur ⁇ ing a fire is considerably reduced.
- the mineral wool When applying the idea of one or more resilient edges for fire insulation on metal constructions, the mineral wool would typically have a higher density compared to heat insulation in a building.
- the density of the mineral wool board according to this embodiment would typically be in the range of more than 60 to 150 kg/m 3 , preferably in the range of 70 to 140 kg/m 3 , and even more preferably in the range of 80 to 130 kg/m 3 . This range is often used for fire protection on ships. For fire protection on off-shore installations densities up to 165 kg/m 3 are used.
- the product Conlit® is a stone wool based product developed for optimal fire protection characteristics. This product has densi ⁇ ties in the range 150 - 190 kg/m 3 .
- the thickness of fire insulation may be down to the range 20 - 75 mm.
- a preferred embodiment for manufacturing the mineral fibre insulation board according to the invention is to let a stack of 4 - 8 boards pass a first zone with 2 - 4 rollers on one side of the conveyor and a smooth conveyor surface on the opposite side of the rollers for holding the stack of boards in position. This is necessary due to the high density of the boards.
- the distance be- tween the rollers and the opposite smooth surface must be adjusted so that the rollers will compress the edges of the boards the necessary distance, e.g. 20 mm giving a resilient depth of the surface of approximately 10 - 12 mm.
- the two resilient edges on the inventive insulation board preferably should have a common corner to facilitate easy installation, the stack of boards is turned 90 degrees after the first compression.
- the stack will pass a second zone with 2 - 4 rollers on one side of the conveyor and a smooth conveyor surface on the opposite side of the rollers.
- a third and a fourth zone could also be applied if more than two resilient edges on the boards are needed.
- the stack of boards could pass the same zone more than one time after being rotated. This would reduce the necessary equipment on the factory line.
- Another preferred embodiment for manufacturing the mineral fibre insulation board according to the invention is to let one board pass a first zone with 2 - 4 rollers on one side of the conveyor and a smooth conveyor surface on the opposite side of the rollers. Then the board is turned 90 degrees and follow ⁇ ing this the board will pass a second zone with 2 - 4 rollers on one side of the conveyor and a smooth conveyor surface on the opposite side of the roll ⁇ ers. While passing the first zone and the second zone the board is being supported on its top major surface. This support could be in the form of a conveyor band covering the majority of the top surface preventing the board from bending due to the compression force. Also in this embodiment the more than two zones may be needed, and the board could pass the same zone more than one time.
- Another way to provide the insulation board with resilient zones along edges is to cut a pattern with knifes or saws in the edge, or to enter a number of needles or nails a certain distance into the edge.
- the resiliency will be de ⁇ termined by how close and how deep the cuts are made or how close and how deep the needles are entered.
- a further method for improving the resiliency of the insulation board is to pro ⁇ quiz this according to the folding method described in EP 741 827 B1.
- the folding technique is illustrated in figure 1 and 3 of EP 741 827 B1 and de ⁇ scribed in claim 1 step f). This folding will arrange the fibres predominantly perpendicular to the major surfaces of the fibre web being produced. The folding will therefore also increase the resiliency of the web in the production conveyor direction. When this web is cut into insulating boards, these boards will be more resilient in one direction when pressing on two opposite edges than in the direction perpendicular to this when pressing on the two other edges. Thereby the demands for the resiliency of the edges are reduced.

- Figure 2 Four boards without resilient edges mounted on a facade
- Figure 3 Four boards without resilient edges mounted on a non-planar facade
- Figure 4 Four boards with resilient edges mounted on a facade Figure 5 A stack of boards passing a compression station seen from top.
- Figure 6 A stack of boards passing a compression station seen from the side.
- the mineral fibre insulation board 1 in figure 1 has two resilient edges 2 meeting in the upper left corner 3. This makes it possible to install the insula ⁇ tion in an easy way so that all connections between boards can be made in ⁇ volving at least one resilient edge.
- Figure 2 illustrates the result of installing boards 1 without resilient edges. Due to the inaccuracy of cutting out the boards different gaps between the installed boards will occur. If the edge are not strictly perpendicular to the major surfaces, a V-shaped gap 4 may be the result. The open side of the V may be on both sides of the insulation 4, 5. If the board shape deviates from a rectangular box shape several open gaps may occur between the boards 6.
- Figure 3 illustrates the result of installing boards 1 without resilient edges when the wall surface is non planar. V-shaped gaps 7 will be the result even if the shape of the boards is perfect.
- Figure 4 illustrates equivalent situations as in figure 2 and 3, but with use of the new board with resilient edges. In this case there are no gaps between the boards.
- Figure 5 shows the compression station from above and figure 6 shows it from a side view.
- the stack of boards 22, which also could be one single board 1 is moved on the conveyor (not shown) along the factory line.
- the rollers 20 will compress one edge slightly in a local zone.
- the first roller 20 which is being passed will often extend a shorter distance into the stack of boards 22 than the following rollers 20' and 20". It is important that the whole minor surface is compressed in this process.
- the mineral fibre insulation board is made for being applied for heat insulation of building facades.
- the density of the board is approximately 60 kg/m 3 , preferably more than 60 kg/m 3 , it has a length of 600 mm a height of 1000 mm and a thickness of 200 mm.
- the board has two edges which are made resilient into a depth 10 - 12 mm. These two resilient edges have one corner in common.
