Definitions

  • the present invention relates to a wall insulation system for a double shell exterior wall, and a method for assembling such a wall insulation system.
  • US 3,812,635 A discloses a method for fabricating an insulated wall.
  • a well-known construction system for exterior walls when constructing new buildings is a two-shell exterior wall comprising at least three layers: an inner shell, an outer shell and insulation means between the inner and the outer shell.
  • Buildings with this type of exterior walls are typically constructed so that the inner shell wall is built first, and then the insulation layer and the outer shell layer are provided subsequently. When the insulation layer is in place, heat can be applied to the interior of the building to dry out the construction if needed, and thereafter the interior construction can begin. Insulation is typically provided as an intermediary layer between the inner and the outer shell. In the construction process, the insulation layer is usually provided simultaneously with the outer shell, such that a first section of insulation is provided, e.g. a section extending one meter from the ground in parallel with the inner shell. This section of insulation is then covered by a corresponding first section of the outer shell, e.g. a masonry or brick facing wall.
  • thermal bridges may be formed, which are highly undesirable in the finished construction.
  • the construction worker is therefore faced with extra work during the process, since the thermal bridges need to eliminated by filling the formed air spaces with extra insulation, e.g. in the form of compressible insulation strips or the like. This step thus further adds to the cost and the time needed to achieve a completed insulation layer with minimal thermal bridging.
  • a wall insulation system for a double shell exterior wall which comprises an inner shell extending in a first plane and an outer shell defining an intermediary space between them, and mounting anchors defining a second plane and extending substantially perpendicularly to the first plane, and being fastened to the inner shell with lateral offsets, and in rows with uniform elevation offsets from one another, wherein the mounting anchors comprise securing means and in an assembled state bridge the intermediary space, and further comprising at least one first insulation layer having insulation elements, which are supported by the mounting anchors in the intermediary space between the inner shell and the outer shell, wherein said insulation elements have a width in the direction between two adjacent rows of the mounting anchors and a length extending perpendicularly to the width, wherein each insulation element a main portion having a comprises a back surface, top and a bottom flange protruding from the main portion and extending along the length of the insulation element, wherein said top flange is configured to
  • the object of the invention it is possible to complete the at least one first insulation layer independently of the construction of the outer shell. This provides for an easier and more simple task for the construction worker compared to known methods, and he/she only need the materials for the assembly of the at least one first insulation layer at hand.
  • the insulation layer can be completed even without the immediately subsequent completion of the outer shell, as the assembly of the insulation layer is a stable construction that does not require to be immediately supported nor protected by the completion of the outer shell. This is because the mounting anchor penetrates the bottom flange and a locking effect is provided, such that a lower insulation element, is kept in place as well by the attached insulation element above it.
  • the interior construction can begin, even if the construction of the outer shell is halted, e.g. to outdoor temperatures or material shortage.
  • both time and cost can be minimized when constructing double shell exterior walls of the type mentioned above.
  • the mounting anchors may be fastened during the initial production of the material which constitutes the inner shell, or the mounting anchors may be fastened post production. By penetration is meant that the insulation element is pushed over the mounting anchor.
  • the insulation element may be understood as one insulation element, not two or more elements being parallel displaced, forming a stepped profile.
  • the dimensions of the insulation element in the width direction is chosen according to the distance between adjacent rows of mounting anchors which is typically standardized measurements according to established building standards.
  • the top flange and the bottom flange are configured to protrude from said main portion on each side of a longitudinal centerline in the width direction of said insulation element, so as to form a stepped portion or beveled face comprising a flange surface and a main portion surface at a top and bottom region of said insulation element.
  • the flange surface at the top region and the main portion surface at the bottom region of said insulation element, during assembly, together provide for guiding means for the insulation element in that the distance between two adjacent rows of mounting anchors corresponds to the distance from the flange surface at the top region to the main part surface of the bottom region of the insulation element.
  • the flange surface at the top region and the main portion surface at the bottom region of said insulation element are substantially horizontal. This way, the assembly work done by the construction worker is made easier in that the flange surface at the top region and the main portion surface at the bottom region are parallel with the mounting anchors. Thus, the flange surface at the top region and the main portion surface at the bottom region of the insulation element contact the mounting anchors. Thus, the insulation element is guided between the rows of the mounting anchors, while the construction worker pushes the insulation element towards the inner shell and into position.
  • At least one mounting anchor penetrates at least one of said top and/or bottom flanges in the assembled state.
  • the mounting anchors help support the insulation elements as the insulation elements rest on the mounting anchors in addition to resting on the insulation element(s) below.
  • the insulation layer is fastened by means of mounting anchors in that a mounting anchor penetrates a top and/or bottom flange. This way, a stable and coherent surface facing away from the inner shell is provided.
  • the securing means is configured to abut this coherent surface.
  • coherent means that the surface is constituted by one insulation element, i.e. the securing means abuts a surface of a single insulation element.
  • a ratio between the extension of the top flange in the second plane and the extension of the bottom flange in the second plane is approximately in the range from 2/98 to 98/2, preferably 25/75 to 75/25, more preferably 40/60 to 60/40, most preferably approximately 50/50.
  • the ratio between the extension of the top flange in the second plane and the extension of the bottom flange in the second plane is chosen while balancing two objects. Firstly, the stability of the insulation element in that the flange which is to be penetrated by a mounting anchor has to be sufficiently stable not to be deformed or even broken, when the insulation element is pressed against the mounting anchors in order for it to penetrate the flange. Secondly, the ease of assembly for the construction worker, as it is highly desirable that the assembly of the insulation layer and thus the penetration of the flange does not require too much force applied by the construction worker in order for the work not to be too strenuous. The ratios above balance these two objects and are stated in an order of preference.
  • the insulation elements of the at least one first insulation layer are made of a weather-resistant material.
  • weather resistance means that the material of the insulation elements of the at least one first insulation layer is suitable for being subjected to e.g. precipitation without being covered and thus protected by an outer shell functioning as a climate barrier over a longer period of time, e.g. 4-5 months, and still maintains its insulation capacity in the finished construction.
  • the completed first insulation layer can be subjected to normal Scandinavian climate exposure conditions for longer periods of time, while the wall insulation system, including the outer shell, is under construction.
  • the material is not deteriorated by normal precipitation, e.g. 300 mm over approximately 4-5 months.
  • construction of the outer shell is also used to keep the insulation layer in place.
  • the inner shell In cold climates, the inner shell has to be insulated before the interior construction can begin.
  • many materials used for the completion of the outer shell cannot be used below certain outdoor temperatures.
  • the overall construction process of a building of this type is somewhat halted at cold temperatures. This prolongs the construction process and makes it significantly less cost-effective.
  • the wall insulation system of the invention enables the completion of the assembly of the at least one first insulation layer without the need for a simultaneous completion of the outer shell.
  • the interior construction can begin, and the construction of the outer shell can take place independently, when e.g. the outdoor temperature according to the chosen materials of the outer shell so allows.
  • the insulation elements of the first insulation layer are made of mineral wool, preferably at a density of 45 to 150 kg/m 3 .
  • Glass wool and stone wool have proven to be suitable materials for the invention in that they are not damaged by precipitation.
  • insulation elements of relatively high dimensional stability which means that a relatively tight fit can be achieved between the insulation elements so as to achieve an insulation layer without significant gaps which can cause thermal bridging.
  • a certain dimensional stability is important for the insulation elements to be assembled to a insulation layer according to the invention.
  • the insulation elements of the first insulation layer are of a laminated structure comprising at least two components made of different materials and/or having different densities.
  • the two components do not necessarily have to have the same properties.
  • the outermost component can be made of a material which is better suited for exposure to weather, whereas the innermost component may be of a material which is for example more stable, strong or cheap compared to the material of the outermost component.
  • the at least two components are offset in the width direction so as to form an insulation element with a top flange and a bottom flange. This way, the cost of manufacturing profiled insulation elements is eliminated.
  • the wall insulation system comprises at least one second insulation layer.
  • the insulation elements of the second insulation layer do not necessarily have to have the same properties as the insulation elements of the first insulation layer.
  • an insulation element of the second insulation layer does not have to be profiled so as to obtain a partial overlay over the insulation element below as is the case for the insulation elements of the first insulation layer. This means that the insulation elements of the second insulation layer can be manufactured in a simpler and thus less expensive way than the insulation elements of the first insulation layer.
  • insulation elements of the at least one second insulation layer are made of a different material than the insulation elements of said first insulation layer.
  • the insulation elements of the second insulation layer do not necessarily have to the same properties as the insulation elements of the first insulation layer.
  • the material of the insulation elements of the second insulation layer does not have to have the same characteristics as the material of the insulation elements of the first insulation layer.
  • it can e.g. be chosen to be a less expensive material than the material of the insulation elements of the first insulation layer.

  • the shape of the insulation element differs slightly from the previously described embodiments.
  • the insulation element 841 of the embodiment in Fig. 13 comprises two protruding flange portions, a top flange portion 853 and a bottom flange portion 854 similarly to the flange portions in the previously described embodiments.
  • the flange portions substantially form a stepped portion, such as a staircase structure, where an end of each component 850, 851, 852 each defines a step surface 853a, 853b, 853c in the top region and a step surface 854a, 854b, 854c in the bottom region.
  • the main portion 842 from where the flanges protrude is thus defined along the borderline of step surface 853c in the top and step surface 854a in the bottom. That is, the step surfaces 853a and 854a together define the guiding means of the embodiment in Fig.
  • both the protruding flange portion of the second 851 and third 852 component of the insulation element 841 are penetrated by the at least one mounting anchor in an assembled state as already described with regards to the previously described embodiments.
  • Fig. 14 shows three different solutions all suitable for a plastered facade.
  • a mounting anchor 8 with engagement means 208a in the form of disc with an eye or hole is provided. The disc placed in parallel and in extension of the mounting anchor is easy to use for penetration of the insulation element 41, 51 during mounting due to its flat configuration. After mounting of the insulation element 61, a securing means 6 is placed over the mounting anchor.
