Definitions

  • the invention relates to a new building insulation product type suitable for use on facade or external wall surfaces, and especially uneven façade surfaces for example in renovation of facades of older buildings.
  • the object of the present invention is to provide a mineral wool i.e. a stone wool or glass wool insulation product where at least one of the disadvantages of the prior art is eliminated or at least alleviated.
  • the objects of the present invention are achieved with an insulation product, a method for manufacturing such a product and use of the product in façade renovations according to the characterizing portions of the independent claims.
  • the present invention is directed to a mineral wool insulation slab for façade renovations, comprising a rigid insulation slab or lamella, having a density of 20 - 120kg/m 3 , wherein the insulation slab or lamella has an outer and an inner side, wherein the outer side of the slab comprises an outer layered surface and the inner side of the slab is a mechanically and/or chemically softened layer, which is essentially softer than the rest of the slab.
  • the invention is further directed to a method for manufacturing of a mineral wool insulation slab for façade renovations comprising a rigid insulation slab or lamella , having a density of 20 - 120kg/m 3 , wherein the insulation slab or lamella has and outer and an inner side wherein the method comprises the steps of softening of the inner side of the insulation slab mechanically or chemically, and adding an outer layered surface to the outer side of the insulation slab.
  • façade is used in its traditional sense as the outer surface of a building, but is here to be understood in a broader sense to also comprise the case when a wall is cleaned from the old insulation/old façade surface, i.e. when the inner concrete core is remaining.
  • the present invention is directed to a building insulation product suitable for use in façade renovations. More specific the invention is directed to an insulation product or an insulation slab or lamella comprising a wind protective surface layer or coating, a thick and dense insulation layer and a softened back side. Especially if the surface of the wall to be insulated is uneven, an installation of an insulation slab or lamella directly on the surface may lead to a situation where air voids are created between the insulation slab and the uneven façade surface. This leads to a situation where there is a serious risk of internal convection which weakens the insulation value of the whole construction. Traditionally this has been solved by installing a separate soft insulation mat between the façade surface and the insulation slab. There is a need to simplify the current solutions which require several installation stages, and separate fasteners for the separate layers, which are time consuming to install and expensive.
  • a building insulation product comprises a rigid insulation slab or lamella of mineral wool.
  • the mineral wool slab may for example be a glass wool or stone wool slab.
  • the core of the slab or lamella consists of a thick and dense insulation layer.
  • the insulation slab or lamella comprises a softened layer, which is part of the insulation slab itself but has been either mechanically or chemically softened.
  • the inner side of the slab is a mechanically or chemically softened layer of the one and same insulation slab, i.e. the inner side is not a softer layer glued to the rigid core layer of the insulation slab.
  • the present invention solves this problem by providing a 3-in-one insulation slab or lamella comprising a core of rigid, dense insulation material, with an outer surface comprising an outer layer and a softened backside.
  • a softened backside of the insulation slab will allow the insulation slab to be installed in one piece on the façade surface, it may be installed as a single layer and it will prevent any air voids from being created, since the softened backside will be tightly pressed against the façade surface due to the lower density of it.
  • the density of the insulation slab or lamella is 20 - 120kg/m 3 , preferably 40 - 100kg/m 3 .
  • the density of the softened backside is essentially lover than the density of the slab itself. I.e. the backside is softened to a degree where stones, bulks or other uneven bumps in a façade surface will sink into the insulation slab when installed in the façade surface.
  • the density of the softened backside of the insulation slab or lamella is less than 108 g/m 3 . According to a preferred embodiment the density of the softened layer is between 18 and 108 kg/m 3 , and preferably between 30 and 80 kg/m3.
  • Figure 1 describes the problem to be solved by the invention.
  • bumps or dents 1 in a façade surface may prevent a rigid insulation slab 2 from being tightly closed against the façade surface 3, thus creating air voids 4 between the insulation slab 2 and the façade surface 3.
  • Figure 2 describes a currently used solution.
  • a separate soft insulation mat 5 is first installed at the façade surface in order to smoothen out the cavities and dents in the concrete.
  • a soft insulation mat used for this purpose is a product called UNM 37, which has a density of 26-45kg/m3.
  • the soft insulation mat is fastened with its own fasteners 6 before the rigid insulation slab 2 may be installed on top of the soft insulation mat 5.
  • the rigid insulation slab must be installed in a separate installation stage with separate fasteners 7 to those used to fasten the soft insulation mat.
  • air voids are avoided but installation is time consuming and requires multiple fasteners.
  • Figure 3 describes an embodiment of the invention wherein the insulation slab or lamella 10 according to the invention comprises a softened backside 11, a rigid core 12 and a wind protective surface or coating 13 on the opposite side from the softened backside 11 of the insulation slab 10.
  • one set of fasteners 14 may be used to install the 3-in-one insulation slab.
  • the soft backside of the insulation slab may be tightly installed against the uneven façade surface, leaving no air voids between the surface and the slab.
  • a separate façade surface 15 may be installed at the outer side of the insulation slab, preferably leaving a ventilation gap 16 between the new façade surface and the newly installed insulation layer.
  • Figure 4 describes an alternative embodiment according to the invention.
  • a rendered façade surface or coating 17 may be applied directly on the outer surface of the insulation slab.
  • the insulation slab still comprises a softened backside 11 and a rigid core 12 of dense insulation material.
  • the insulation slab may be fastened on the façade surface in one installation stage with a single set of fasteners 14.
  • the softened backside of the insulation slab may be achieved either by mechanical or chemical softening. It is also possible that both softening methods, the mechanical and chemical softening are used on the one and same insulation slab to soften the backside of the slab.
  • the backside of the insulation slab may be cut with blades to create grooves in the slab. Another option is to use metal molds to cut a pattern in the backside of the slab. Using spikes or needles to stab the backside of the slab is another preferred option, which also will decrease the density of the material.
  • the backside of the slab may also simply be mangled, which makes it softer than the rest of the rigid insulation slab.
  • the softening may be carried out as a step of the manufacturing process.
  • the slab As an insulation slab is produced on a factory line, the slab may as a last step at the line be fed over a cutting roll or mangle.
  • the insulation slab may then be feed on the line where a cutting roll or mangle has been installed at the bottom of the line.
  • the insulation slab is then fed over the cutting roll or mangle and is optionally pressed down toward the cutting roll or mangle.
  • the cutting roll or mangle will then over the width of the insulation slab either cut or mechanically mangle the underside of the insulation slab, which underside will become the backside of the finished product.
  • a cutting roll of figure 5b is used.
  • the cutting roll comprises blades along the perimeter of the axis of the cutting roll. The blades will, when an insulation slab is fed over the cutting roll, cut into the insulation slab creating cuts in the direction of the line over the entire length of the insulation slab.
  • the distance between the cuts is 0,5 cm - 2,5 cm, more preferably 1cm - 2cm.
  • the cuts are preferably 10-100mm deep, more preferably 20-50 mm deep.
  • Figure 5c shows a cutting roll used in another preferred embodiment.
  • the cutter roll comprises around its axle multiple metal molds placed next to each other preferably covering the entire surface of the cutter roll.
  • the metal molds form a grid on the surface of the cutter roll.
  • the metal molds form a dense pattern thereby creating a pattern in the insulation slab where the distance between to cuts is preferably less than 5 cm, more preferably less than 2,5 cm.
  • the cuts are preferably 10-100mm deep, more preferably 20-50 mm deep.
  • the cutting roll comprises spikes or needles covering its surface.
  • the spikes or needles on the roll are 2cm - 5cm long and at a distance of 0,5 - 2 cm apart from each other.
  • a mangle which can be seen in figure 5a , is used for softening of the backside of the insulation slab.
  • An insulation slab is fed over the mangle and pressed against it.
  • the mangling softens the surface of the rigid insulation slab, thus creating a softened backside of the product.
  • the softening of the back side of the insulation slab may be made by chemical softening.
  • a chemical agent may be added to the backside of the insulation slab during manufacturing.
  • Another option is to add less binding agent to the back side of the insulation slab during manufacturing, which would result in a softer layer at the surface of the insulation slab.
  • the density of the softened backside is 5-70% less than that of the core of the rigid insulation slab, preferably 7-50% less and most preferably 10-30% less.
  • Examples of insulation slabs or lamellas that may be used as a base for manufacturing of a insulation slab according to the invention are Cortex One, with a density of 50-65kg/m 3 , WAS 35 with a density of 70-85kg/m 3 , or Linio 80 which is a lamella, with a density of 75-85kg/m 3 .
  • Cortex One with a density of 50-65kg/m 3
  • WAS 35 with a density of 70-85kg/m 3
  • Linio 80 which is a lamella, with a density of 75-85kg/m 3 .
  • an outer layered surface is added to the outer side of the insulation slab during manufacturing.
  • the adding of the outer layer may comprise gluing or spraying a wind protective surface or coating or a rendered surface to the insulation slab.
