Definitions

  • the present invention relates to an insulation structure according to the preamble of claim 1.
  • the invention furthermore relates to a method of laying an insulation structure on a supporting base layer, and to a lamella.
  • a layer of insulation is provided on a supporting layer of e.g. concrete, lightweight concrete or profiled steel plates.
  • a layer of insulation is provided on a supporting layer of e.g. concrete, lightweight concrete or profiled steel plates.
  • the insulation roof covering means such as roofing felt or foil is positioned, forming the exterior of the roof.
  • a problem with the current insulation lamellas is that when you have an inclined roof, where the insulation lamellas are wedge shaped, such that the insulation lamella has an inclining upper surface extending in the length direction of the insulation lamella, the lamellas are laid in columns extending across the inclination.
  • the lamellas are laid in columns extending across the inclination.
  • DE 31 18 495 A1 shows several small wedge-shaped lamellas being held together by a thin roof covering layer assembled and distributed to the roof in rolls and laid out in columns. This makes it hard to secure a fully insulated roof when the roof mounting personnel cannot see if the insulation fits well together. Furthermore, walking on the insulated roof will cause damage to the roof covering and also, it is hard to make proper cuts in both materials when there are openings in the roof, and the cut away excess material will be waste that has to be disposed of.
  • EP 2 126 243 B1 is a similar type where the lamellas are glued together with a cement board on a production site and when delivered to the installation site is heavy and hard to cut, as insulation and cement plate have to be cut off when there is an opening in the roof. The excess material is waste in this case as well. So, there is still room for improvement as regards the cost efficiency in the manufacture and mounting of the prior art insulation structures.
  • this object is met by an insulation structure of the kind mentioned in the introduction and which is furthermore characterized in that a difference in distance between the base surface and the first outermost edge and between the base surface and the second outermost edge of the at least two insulation lamellas defines the inclination of the top surface of the insulation lamella structure, and that the insulation structure furthermore comprises a separate pressure distributing layer provided on the top surface of the insulation lamella structure.
  • a cross-section of the insulation structure along the inclination of the top surface of the insulation structure may exhibit a continuous inclining top surface, a stepwise inclining top surface or a combination thereof.
  • the general impression of the surface is that it is sloping, however, the sloping surface may be reached through lamellas with a top side being parallel to the base plane, but the distance between the top side of the individual lamellas and the base plane increases, creating a stepwise inclining surface.
  • the insulation lamellas may also have an inclining top side, creating a continuous inclining top surface of the insulation structure.
  • the at least one of the at least two insulation lamellas is in an unfolded state and, where said insulation lamella is in a folded state, it may be provided with at least one split along the length, providing at least two lamella parts each having a first and a second side extending along a length of the lamella part, the first side facing the at least one first split in a folded state, the second side opposing the first side and the at least two lamella parts in a folded state are attached to each other along the length by a thin neck.
  • the neck acts as a rotation axis allowing folding and unfolding the lamella without separation of the lamella parts.
  • mineral fibrous insulation with the fibres oriented substantially parallel to the plane of the neck like glass wool, provides excellent flexibility and is beneficial.
  • the at least one of the at least two insulation lamellas is in an unfolded state and said insulation lamella in a folded state may be provided with at least one first split along the length, providing at least two lamella parts each having a first and a second side extending along a length of the lamella part, the first side facing the at least one first split in a folded state, the second side opposing the first side and the second side being arranged with an inclination in relation to the first side wherein the at least two lamella parts in a folded state are attached to each other along the length by a thin neck, the at least two lamella parts each being adapted to be turned substantially 180 degrees in relation to the at least one adjacent lamella part, the centre of rotation being the thin neck, such that at least one first side of at least one lamella part, or its opposing second side on the same lamella part, is positioned substantially parallel to the base plane in an unfolded state.
  • the insulation structure wherein at least one of the at least two insulation lamellas is in an unfolded state and wherein said insulation lamella in a folded state, may be provided with a split along the length, providing two lamella parts each having a first side and a second side extending along a length of the lamella part, the first side facing the split in a folded state, the second side opposing the first side and the second side being arranged substantially parallel and with a distance in relation to the first side, said distance being different for the two lamella parts in the insulation lamella, wherein the at least two lamella parts in a folded state are attached to each other along the length by a thin neck, the at least two lamella parts each being adapted to be turned substantially 180 degrees in relation to the adjacent lamella part, the centre of rotation being the thin neck, such that the first sides of each of the two lamella parts, is positioned substantially parallel to the base plane in an unfolded state.
  • a stepwise inclining surface of the insulation structure may be provided with
  • the thin neck may be constituted by the material of the insulation lamella. This makes it easier to produce the lamella.
  • the thin neck may be provided by a secondary layer of another material, for instance a laminated layer in the insulation lamella, or hinges or joints of a separate material.
  • the insulation lamellas may be of a fibrous material, wherein fibres of the two or more insulation lamellas may be adapted to extend substantially perpendicularly to the base plane when positioned on the base layer. This may apply both to the insulation lamellas and/or the lamella parts.
  • the fibrous material may be mineral wool such as glass wool or stone wool. A fibre structure like this will make it very easy to cut the lamella along the fibres as this is often needed when installing.
  • the compressive strength of said insulation lamella in a direction perpendicular to said base plane may be above 30 kPa, preferably between 45-70 kPa. It is understood that compressive strength is measured at 10% deformation according to the standard EN13162 Thermal Insulation products for buildings - Factory made mineral wool (MW) products. This compressive strength makes it possible to walk on the lamella, and thereby easy to work with. Additionally, using lamellas with a high compressive strength as seen in a direction perpendicularly to the base plane will also increase the insulation's ability to carry a snow load.
  • the insulation lamella in a folded state may be provided with at least one second split in addition to said at least one first split from the respective opposite side of where said at least one first split is provided, such that fanfolds and at least three lamella parts are created.
  • the fanfold of three or more lamella parts can make it easier to keep track on installing the many lamella parts correctly.
  • One or both lamella parts at the end of the fanfold may also have an inclining second side or first side when in a folded state.
  • the at least one edge of at least one insulation lamella may be cut, such as by chamfering or filleting.
  • the cut can also be rectangular as opposed to the triangular shape of chamfering or rounded inwards as opposed to the outwards rounded edge of filleting.
  • a ventilation channel is created.
  • the insulation lamella or lamella part is adapted to be positioned such that the chamfered edge is positioned in the top surface of the insulation structure.
  • the air channel can be used for passively or actively ventilating the roof in order to dry out any moist that may need to vacate the roof.
  • the insulation lamella may be provided with at least one air channel recess in each lamella part, extending substantially perpendicularly in relation to the length of the insulation lamella and placed substantially directly opposite each other, such that when the insulation lamella is in an unfolded state an air channel is extending across the lamella parts.
  • This air channel recess will connect the air channels that extends along the length of the insulation lamella.
  • the insulation structure may be interrupted by an opening or reservation for an element, such as a sky light or a chimney.
  • an element such as a sky light or a chimney.
  • the previously described embodiments will in any combination be easy to install in such interrupted insulation structure.
  • this may create a cut off lamella piece, and this cut off insulation lamella piece or piece of lamella part may be used on the opposite side of the opening for the element.
  • this cut off insulation lamella piece or piece of lamella part may be used on the opposite side of the opening for the element.
  • the insulation structure may provide a grid of connected air channels in the opposing top surface of the insulation structure.
  • air channels usually when air channels only extend in one direction, it is best to position the air channels running from east/west instead of north/south. Thereby the roof is better ventilated because the wind often comes from west, at least in northern Europe.
  • the channels extend in both directions there is no need to plan the orientation of the air channels as any position is as good as another.
  • the grid of connected air channels makes it very likely that a vent placed in one side of the roof will be in air channel connection with another vent placed at the opposite side of the roof. This makes it possible to passively ventilate the whole roof using the pressure difference created by the wind.
  • the insulation lamella structure is constituted by rows of lamellas with successively increasing height, preferably 2 to 10 rows, more preferably 3 to 6 rows, to form a section of lamella rows.
  • the lamellas of a first section of rows are adapted to be positioned directly on the supporting base layer in the mounted condition of the insulation structure, wherein the lamellas of a second section of rows are adapted to be positioned on a plane layer of insulation, and wherein lamellas of optional further sections rows are preferably adapted to be positioned on said first plane layer of insulation and a second, third, fourth etc. plane layer of insulation.
  • the invention also relates to a method of laying an insulation structure on a supporting base layer, comprising the steps of:
  • the unfolding may involve placing a laying device, such as a fork, in the split of the insulation lamella, and rotate one part of the lamella 180 degrees in relation to the adjacent part of the lamella.

  • the lamellas 1 are lengthwise running across the inclination ⁇ created by the lamellas that have been cut at an angle in relation to the base plane and base layer 20 and are typically provided as in the embodiments shown in Figs 6, 7 or 8 .
  • the first and the second outermost edges extends along the length of the insulation lamella.
  • the length of the insulation lamella is preferably longer than it is wide and longer than it is high.
  • the staggered pattern is preferably provided by having insulation lamellas offset in relation to each other along the length of the insulation lamellas or by having a difference in the length of the insulation lamellas. This provides better production tolerances on the length of the lamella. Length tolerances for installing in a staggered pattern can be very coarse, making the lamellas easier to produce, with length cutting techniques fit for mass production, and with less unplanned interruptions of production.
  • the number of different lamellas 1 may be limited, and the size of the lamellas 1 will not get difficult to handle.
  • the insulation lamella structure 11 is here provided with an opening 13, for example for a skylight or a chimney. Because the insulation lamella structure 11 forms a staggered pattern across the inclination ⁇ there is less waste as the pieces 27 of lamellas 1 that have been cut off to make room for the opening 13, can be used on the other and opposing side of the opening 13.
  • Figs 13A-D show an embodiment of an insulation lamella 1 provided with ventilation channels 24.
  • the lamella is seen from two different sides.
  • the split 9 is facing upwards and in Fig. 13B the split 9 is facing downwards.
  • Both figures show the lamella 1 in a folded state.
  • Both lamella parts 2 are provided with chamfered edges 8 extending along the edge of the lamella 1, and two air channel recesses 22 positioned substantially opposite each other, substantially perpendicularly to the length 14 and the base plane BP(x,y).
  • the two air channel recesses 22 are shown as located more or less accurately opposite each other, slight variations in the positions do not hinder the air channel from functioning, even if the recess placing should drift a bit.
  • Figs. 14A-B shows an embodiment of an insulation structure 111 provided with ventilation channels 24 as seen from the front and from the side, respectively.
  • the air channels 24 are formed by either the chamfered edges 8 of two lamellas 1 placed side-by-side ( Fig. 14A ) or by the recess 22 in the lamella part 2.
  • the recesses 22 can be formed by other geometry of the cross-sectional area and there can be more recesses 22 per lamella 1.
  • insulation lamellas 1 with tapered lamella parts 2 have been used.
  • the lamellas have been covered with a pressure distributing board 7.
  • the lamella parts 2 are positioned on a substantially horizontal base layer 20, where the inclining side 16 of the lamella 1 is facing upwards, creating a sloping opposing surface 19, such as a roof surface.
  • a sloping opposing surface 19 such as a roof surface.
  • the separate pressure distributing board 7 On top of the lamella parts 2 the separate pressure distributing board 7 has been placed.
  • the lamella parts 2 are being made successively taller or wider depending on the lamella's 1 orientation in relation to the base plane BP(x,y) on the supporting base layer 20. Because of the inclined partial cut in relation to the base plane or supporting base layer 20 the sloping or inclining opposing top surface 19 is continuous.
  • Fig. 15A shows an embodiment of an insulation lamella structure 11 provided with ventilation channels 24 as seen from above.
  • the air channels 24 are extending both along the inclination, established by air channel recesses 22, and across the inclination, constituted by chamfered edges 8, of the insulation lamella structure 11.
  • the insulation lamella structure 11 forms a staggered pattern, and the grid of air channels 24 can be seen as the punctured lines.
  • Fig. 15B shows an embodiment of a similar insulation structure 111 as in Fig. 15A , as seen from above.
  • the insulation structure 111 has been provided with openings 13, such as protruding elements in the form of chimneys, ventilation hoods, skylights or the like.
  • the insulation lamellas 1 that have been cut off, may be used on the other side of the interrupting element 13 due to the staggered pattern of the insulation structure 111.
  • insulation lamella and lamella are both used for the same element. The same applies to supporting base layer and base layer.
