  • 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.

  • the increased cost-efficiency aimed at is attained in that the insulation lamella(s) of the insulation lamella structure can be transported and handled, for instance carried onto the roof structure, while in the unfolded state. Once the folded insulation lamella has been brought to its intended position, it is unfolded to reach the mounted condition. Depending on the number of lamella parts provided in each insulation lamella, only half or less of the number of lamellas need to be handled as compared to the prior art. Furthermore, installing an insulation lamella structure of low thickness is facilitated compared to prior art structures having pre-cut lamellas requiring cutting-through before installation.
  • the thin neck is 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 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 a reservation for an element, such as a sky light or a chimney.
  • an element such as a sky light or a chimney.
  • this may create a cut off lamella piece, and this cut off insulation lamella or lamella part may be used on the opposite side of the opening for the element. Thereby less waste is created, and the installation time for insulating the roof around the element is reduced as the construction worker only have to measure and perform one precise cut making the interrupted lamella fit the element, and then proceed with installing in a staggered pattern at the other side of the element.
  • the insulation structure may be provided with 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 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 in an insulation structure 111 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.
