Definitions

  • the present invention belongs to the field of building construction, and more particularly to the application of an insulation cladding onto the fagade of a building.
  • a first object of the invention is a fagade cladding comprising a multilayer reliable panel that includes a ventilation layer.
  • a second object of the invention is a method for installing the fagade cladding disclosed above. STATE OF THE ART
  • the energy efficiency of a building is the extent to which the energy consumption per square metre of floor area of the building measures up to established energy consumption benchmarks for that particular type of building under defined climatic conditions. Building energy consumption benchmarks are representative values for common building types against which a building's actual performance can be compared. Energy efficiency refers to the use of energy more effectively, and measures differences in how much energy is used to provide the same level of comfort, performance or convenience by the same type of buildings. More particularly, the energy demand of a building shall be determined on the basis of the calculated actual annual energy that is consumed in order to meet the different needs associated with its typical use and shall reflect the heating and cooling energy demands to maintain the comfort conditions in the interior of the building, and supply domestic hot water needs.
  • the building sector represents 40% of the overall energy consumption and 36% of C02 emissions in Europe. Furthermore in Europe more than 70% of the building stock was built before the first energy crisis (70's) without consideration of Energy Efficiency criteria, which involve a poor energy performance. Taking into account these data, by improving the Energy Efficiency of buildings, a reduction of EU energy consumption by 5-6% and C02 emissions by about 5% could be achieved. In this scenario the Energy Retrofitting is envisaged as key strategy to reduce the energy impact of the building sector. In particular, by means of application of passive measures, regarding basically the building envelope, the energy demand may decrease, since the heating and cooling needs decrease, keeping or improving the comfort conditions.
  • a known solution to this problem is the provision of an additional cladding with thermal insulation fixed to the fagade of the building, in order to enhance the thermal performance of the existing envelope and consequently the energy efficiency of the building.
  • the cladding may further comprise features for improving the aesthetic appearance of the building.
  • a typical cladding for energy rehabilitation includes a number of layers, such as e.g. insulation layer and aesthetical layer, fixed one by one to the surface of the walls of the building.
  • the cladding includes also a ventilation gap between the insulation layer and aesthetical layer, which improves the thermal performance.
  • the fixation of the cladding to the walls of the building is very time- consuming, since it involves the fixation to the walls of the building of a high number of separate parts for each layer.
  • the fixation of a cladding involves the provision of scaffolding systems for allowing the workers to access the fagades of the building in each layer application, which usually takes a long time and causes annoyance to the tenants.
  • new claddings for reducing the time required for installation have been envisaged.
  • Document ES2578385 discloses a cladding comprising a panel formed by elements in the form of slats longitudinally connected one after the other in a line.
  • a panel can be rolled for transport and, once on site, it can be simultaneously unrolled and installed by hoisting a free end thereof up the walls of the building by means of a pulley temporarily fixed at the top of the building.
  • a pair of rails previously fixed to the walls of the building ensures that the panel is properly positioned.
  • this cladding panel does not address the problem of thermal insulation, since it only includes slats intended for improving the aesthetical appearance of the building. Indeed, document ES2578385 specifically discloses that, in case an inner thermal insulation layer is needed, it must be installed in advance.
  • Document FR2469519 discloses a cladding for covering the walls of a building comprising a multilayer panel.
  • the layers include basically an insulation layer and an aesthetical layer fixed thereto.
  • the aesthetical layer is formed by elements in the form of slats longitudinally connected one after the other in a line and the insulation layer is a continuous layer formed in an insulating material.
  • document FR2469519 proposes providing a separation gap achieved by means of works in-situ, between the walls of the building and the multilayer panel. However, such a separation gap between the walls and the panel would deprive the cladding from any insulating effect.
  • the present invention solves the aforementioned drawbacks by means of a novel reliable fagade cladding having a multilayer panel comprising an insulation layer, a ventilation layer and an aesthetical layer.
  • This novel multilayer panel is particularly configured for being assembled and rolled in a factory, and then it is stored and subsequently transported in a rolled condition to the relevant building for installation.
  • a first advantage of the reliable fagade cladding of the present invention is that, when installing the multilayer panel, the person in charge of the installation does not have to carry out burdensome additional operations such as securing an insulation layer to the fagade of the building in advance, or providing for a separation gap between the panel and the wall.
  • the multilayer panel comprising the insulation layer can be directly installed by securing it to the fagade of the building, thus saving time and labour.
  • a second advantage of the reliable fagade cladding of the present invention is that the installation of the multilayer panel does not require the construction of any permanent structure for supporting the workers, such as the scaffolding. More convenient means such as cranes or elevators can be employed.
  • a third advantage of the reliable fagade cladding of the present invention is that the multilayer panel is reliable. This is advantageous in that the panel is more easily stored, handled and transported. The panel is produced, assembled and rolled in the factory. Once on site, it is unrolled during installation onto the fagade of the building.
  • the term “longitudinal direction” makes reference to a direction along which the multilayer panel is rolled.
  • the term “lateral direction” refers to a direction perpendicular to the longitudinal direction. Therefore, a multilayer panel according to the invention, which is usually square or rectangular, has two longitudinal ends having a certain width and two lateral sides having a certain length.
  • the "first end' of the multilayer panel refers to a free end thereof when in a rolled condition. Thus, the multilayer panel is unrolled by pulling from this "first end'.
  • the "second end' of the multilayer panel is the innermost end thereof when in a rolled condition.
  • thermally insulating material refers to any material having a thermal conductivity of less than about 0.1 W/m 5 C.
  • the term "fagade” refers to any of the walls of a building where the cladding of the invention is going to be installed.
  • a first aspect of the present invention discloses a rollable fagade cladding for insulating a fagade of a building.
  • the cladding comprises a multilayer panel configured for being rolled along a longitudinal direction.
  • the multilayer panel mainly comprises: a) Insulation layer
  • An inner insulation layer comprises a sheet of a thermally insulating material. Any material capable of providing a substantial thermal insulation, for example having a thermal conductivity of ⁇ 0,1 W/m 5 C, can be used for making up the insulation layer. More specifically, the insulation layer is preferably made of at least one of the following materials: flax fiber, hemp fiber, cellulose fiber, aerogel, glass wool, rock wool, mineral wool and polyurethane foam.
  • the insulation layer can have any configuration provided it is rollable along the longitudinal direction. Normally, since several insulation materials are naturally soft and bendable, a sheet made of such materials is rollable. Otherwise, it is understood herein that the sheet of thermally insulating material would be configured for being rollable. Any configuration similar to those disclosed below in connection with the aesthetical layer would be allowable. In this respect, note that no rolling ability is required in the lateral direction, only in the longitudinal direction. b) Aesthetical layer
  • the aesthetical layer is coupled to the insulation layer such that, as disclosed below, a ventilation layer is present therebetween.
  • the aesthetical layer can be made of any material, provided it can be secured to the insulation layer and it can withstand the weather conditions the building is subjected to. More specifically, the aesthetical layer is preferably made of at least one of the following materials: aluminum, steel, PVC, wood, ceramics, stone, fabric, or a composite material. Structurally, the aesthetical layer can have any configuration provided it is rollable along the longitudinal direction. For example, the aesthetical layer may be sufficiently flexible for being rolled. Otherwise, the aesthetical layer may be formed by a plurality of solid parts interconnected by means of flexible joints. For example, regular geometrical parts such as triangles, hexagons, etc. could be employed. In a particular embodiment of the invention, the aesthetical layer comprises a plurality of slats interconnected in a longitudinal direction of the layer. c) Connection means
  • connection means provided along the lateral sides of the multilayer panel, connect the insulation layer and the aesthetical layer.
  • the connection means are configured for separating the insulation layer and the aesthetical layer such that a ventilation layer allowing the passage of air is provided therebetween.
  • the ventilation layer refers to an essentially continuous separation (such as an air gap) between the insulation layer and the aesthetical layer such that they do not touch each other.
  • connection means are preferably configured such that the insulation layer is longitudinally slidable in relation with the aesthetical layer. This feature is important in that a relative longitudinal displacement between the insulation layer and the aesthetical layer may appear when the multilayer panel of the invention is rolled/unrolled.
  • the connection means may therefore allow for the insulation layer to slide longitudinally with respect to the aesthetical layer, thereby ensuring that the multilayer panel can be properly rolled. Otherwise, the multilayer panel could not be rolled/unrolled properly because some or all of the layers, at least the insulation layer, would deform.
  • connection means between the insulation layer and the aesthetical layer could adopt any configuration provided the above conditions are met.
  • each connection means comprises a first connector or first connecting portion slidingly connected to the insulation layer and a second connector or second connecting portion rigidly connected to the aesthetical layer, where said first and second connectors are separated a distance corresponding to a thickness of the ventilation layer.
  • the first connector or first connecting portion comprises a first flange and a support element stemming from a common plate, said first connector slidably sandwiching a lateral side edge of the insulation layer. Therefore, the distance between the first flange and the support element corresponds essentially to the thickness of the insulation layer.
  • the second connector or second connecting portion comprises a second flange stemming from the common plate and rigidly fixed to a lateral side of the aesthetical layer.
  • connection means accordingly has an essentially U-shape where the common plate makes up the central portion of the U and the respective first and second flanges make up the legs of the U.
  • the support element protrudes from the central portion of the U in a position between the first and second flanges.
  • the separation distance between the first flange and the support element could be slightly smaller than the thickness of the insulation layer. This feature aids the inner surface of the insulation layer to more firmly abut against the fagade of the building without leaving any hollow spaces, thus increasing the insulating capability of the multilayer panel of the invention.
  • both the first flange and the support element must be configured for allowing the insulation layer to slide longitudinally. Therefore, no pointed parts or rough surfaces are allowed in the first connector.
  • the second flange making up the second connector is rigidly fixed to a lateral side of the aesthetical layer by any suitable means. Any fixation means, such as screws, bolts, pins, etc. could be employed for this purpose.
  • a plurality of connection means of this type are provided along the lateral sides of the multilayer panel. Therefore, when assembling the multilayer panel of the present invention, the person in charge of the installation needs only to rigidly secure the second flange of a plurality of connection means to the lateral side of the aesthetical layer, and then slidingly introduce the lateral side edge of the insulation layer between the first flange and the support element of the plurality of connection means. This method is disclosed in more detail below in the present document.
  • the multilayer panel disclosed above therefore eliminates the need to perform additional operations during the installation of the fagade cladding for providing a ventilation layer or an insulation layer. All three layers, insulation layer, ventilation layer and aesthetical layer, are included in a rollable panel that can be easily transported, unrolled and installed.
  • the multilayer panel further comprises additional separation means provided between the insulation layer and the aesthetical layer.
  • additional separation means aid the support elements of the first connector in providing support for the insulation layer. This is particularly useful in a central surface portion of the insulation layer which could otherwise bend or flex towards the aesthetical layer and thereby affect the ventilation layer.
  • the insulation layer normally is not a completely rigid sheet.
  • the additional separation means prevent the insulation layer from bending towards the aesthetical layer, thus ensuring a continuous ventilation layer between the insulation layer and the aesthetical layer. Further, the additional separation means push the insulation layer towards the fagade of the building, aiding the insulation layer to firmly abut against the fagade of the building.
  • the additional separation means comprise a plurality of longitudinally rolling devices ("longitudinally” referring to the direction along which the multilayer panel is rolled). Implementing the separation means as longitudinally rolling devices is further particularly useful during assembly of the multilayer panel, as it makes the introduction of the insulation layer between the first flange and the support element of the first connectors much easier.
  • the rolling devices comprise rolling rods coupled between the support elements of pairs of opposite connection means.
  • the connection means are arranged between the insulation layer and the aesthetical layer along the lateral sides thereof. Particularly, pairs of laterally opposite connection means are provided. The rolling rods are thus coupled between the support elements of opposite connection means.
  • connection means further comprise a laterally outward longitudinal groove adjacent the second flange for receiving a rail secured to the fagade of the building for guiding the multilayer panel.
  • a pair of rails is secured onto the fagade of the building for guiding the multilayer panel.
  • the pair of rails are separated a distance matching the width of the multilayer panel.
  • the multilayer panel can then be positioned such that the grooves of the corresponding connection means provided on either lateral side of the multilayer panel enter into the corresponding rails. Thereafter, the multilayer panel is pulled along the rails until it is completely positioned over the wall.
  • the rails need not be arranged vertically, i.e. they could be oriented in any direction on the wall provided they are parallel and separated a distance corresponding to the width of the multilayer panel.
  • the multilayer panel further comprises an end coupling means configured for rigidly coupling the insulation layer to the aesthetical layer at a first end of the multilayer panel. That is, the end coupling means anchors the insulation layer to the aesthetical layer at the first end, which is the free end when the multilayer panel is in a rolled condition.
  • the end coupling means further comprises hook means allowing the multilayer panel to be hoisted up the wall of the building.
  • a hook means refers to any feature that is suitable for being grasped, coupled, hooked, etc. by the hoisting means.
  • the hook means provided in the end coupling means allows for a hoisting means, such as a crane, or a pulley secured to an upper portion of the building, to pull the multilayer panel upwards or to let it fall downwards in a controlled way.
  • the multilayer panel unrolls as the first end thereof is pulled upwards by the hoisting means.
  • the end coupling means further comprises an additional flange configured for being secured to the fagade of the building.
  • the additional flange could be provided with holes for screws, bolts, or the like.
  • the multilayer panel further comprises an intermediate coupling means configured for coupling the insulation layer at a second end of said multilayer panel to a subsequent insulation layer at a first end of a subsequent multilayer panel.
  • the person in charge of the installation can thus couple a plurality of multilayer panels for covering the fagade of a high building.
  • this intermediate coupling means only provides for a coupling between the respective insulation layers. This is important for the reasons disclosed above as to the need to allow for the insulation layer to slide with respect to the aesthetical layer during rolling and unrolling operations.
  • a complete coupling between adjacent multilayer panels requires also the use of a connection means of the type disclosed above. This is disclosed in more detail below in the present document.
  • a second aspect of the present invention discloses a method for installing a fagade cladding for insulating a fagade of a building.
  • the fagade comprises a pair of rails and the cladding comprises a multilayer panel rolled along a longitudinal direction.
  • the multilayer panel comprises an inner insulation layer comprising a sheet of a thermally insulating material; an outer aesthetical layer coupled to the insulation layer; and a plurality of connection means provided along the lateral sides of the multilayer panel that connect the insulation layer and the aesthetical layer.
  • the connection means are configured for separating the insulation layer and the aesthetical layer such that a ventilation layer allowing the passage of air is provided therebetween. Further, the connection means are configured such that the insulation layer is longitudinally slidable in relation with the aesthetical layer.
  • the method comprises the following steps:
  • the hoisting means could comprise a crane or, more preferably, a pulley anchored to an upper portion of the wall provided with a rope. A lower end of the rope is connected to the first end of the multilayer panel, while an upper end of the rope passes around the pulley and it is pulled from.
  • the method of the invention further comprises a step of connecting a second end of the multilayer panel to a first end of a subsequent multilayer panel. This connection step can be carried out at ground level, and therefore no scaffolding means is necessary for this step either.
  • a third aspect of the present invention is directed to a method for rolling a multilayer panel comprising: an inner insulation layer comprising a sheet of a thermally insulating material; an outer aesthetical layer coupled to the insulation layer; and a plurality of connection means provided along the lateral sides of the multilayer panel that connect the insulation layer and the aesthetical layer.
  • the connection means are configured for separating the insulation layer and the aesthetical layer such that a ventilation layer allowing the passage of air is provided therebetween. Further, the connection means are configured such that the insulation layer is longitudinally slidable in relation with the aesthetical layer.
  • the rolling method comprises the following steps: 1 ) The aesthetical layer is laid on a horizontal surface.
  • a first plurality of connection means is secured to one lateral side portion of the aesthetical layer.
  • a first end of a plurality of additional separation means, such as rolling devices, is connected to the first plurality of connection means.
  • the rolling devices could be rotatably fixed, for example, to respective support elements of the connection means.
  • the rolling devices may have end pins configured for being introduced in corresponding holes provided in the support elements, thus allowing the rolling device to rotate.
  • a second plurality of connection means is secured to another lateral side portion of the aesthetical layer opposite said one lateral side portion, and a second end of the plurality of additional separation means is connected to said second plurality of connection means.
  • the insulation layer is introduced longitudinally between respective first flanges of the plurality of connection means and the separation means by pushing it longitudinally. A distance between a leading end of the insulation layer (subsequently second, inner end of the insulation layer when rolled) and a respective end of the aesthetical layer (second, inner end of the aesthetical layer when rolled) is left. Accordingly, since both the insulation layer and the aesthetical layer have the same length, a distance between the first ends of the insulation layer and the aesthetical layer is present in the finished, but still unrolled, multilayer panel.
  • Said distance is calculated for said first, outer ends of the insulation layer and the aesthetical layer to be flush when the multilayer panel is in a rolled condition. 6)
  • the multilayer panel is rolled with the second end of the insulation layer and the aesthetical layer on the inside of the roll.
  • the first end of the insulation layer progressively slides while the multilayer panel is rolled, and at the end of the rolling process said first, outer ends of the insulation layer and the aesthetical layer are flush.
