Description

Title of the invention: Composite insulation panel, composite insulation system and method for manufacturing such a composite insulation panel

[0001] The present invention relates to a composite insulation panel, a composite insulation system comprising at least two composite insulation panels and a method for manufacturing such a composite insulation panel.

[0002] The present invention relates to the field of building, more particularly to the field of insulation of a building and, more specifically, to the field of manufacturing insulation devices for such a building, this from the inside of this building.

[0003] Building insulation devices in the form of insulation panels made from expanded polystyrene foam, polyurethane foam, mineral wool, cellulose wadding, or wood fibers are already known. Such insulation panels are quite thick, so that when fixed to the inner face of a building wall, they significantly reduce the building's living space.

[0004] A solution to this problem has been provided in the form of a vacuum insulation panel, commonly referred to as "VIP," which is an acronym for the Anglo-Saxon term "Vacuum Insulation Panel." Such a vacuum insulation panel has a reduced thickness compared to the insulation panels mentioned above, thus limiting the loss of living space.

[0005] However, such a vacuum insulation panel has the disadvantage of not being able to be drilled or cut without losing its insulating properties. Therefore, when insulating a wall with such vacuum insulation panels, it is essential, firstly, to create a particularly detailed and precise layout of the wall to be insulated before sending the layout details to a manufacturer for the production of the vacuum insulation panels. These operations are particularly delicate, lengthy, and time-consuming, which negatively impacts the building's insulation timeframe. Furthermore, these operations, as well as the handling and installation of these vacuum insulation panels, require the intervention of qualified personnel with specific expertise.

[0006] Another drawback of these vacuum insulation panels is that, once the vacuum insulation panels are fixed to the wall, they must be jointed, coated, and finished. Again, these operations are delicate and time-consuming and require the intervention of personnel. qualified and expert.

[0007] The present invention is intended to remedy, at least in part, the drawbacks of prior art insulation devices.

[0008] To this end, the invention relates to a composite insulation panel which comprises, on the one hand, a vacuum insulation panel which has two large parallel faces as well as lateral sides, and, on the other hand, a coating, which covers at least a part of one of the two large parallel faces of the vacuum insulation panel, and which comprises a mixture which contains at least jute and at least corn.

[0009] Another characteristic relates to the fact that the coating contains at least, on the one hand, between 50% and 70% by mass of jute and, on the other hand, between 30% and 50% by mass of corn, so that the sum of the percentages is at most equal to 100%.

[0010] Another characteristic is that the composite insulation panel includes a covering element that covers at least part of the cladding and extends over at least part of it. This covering element includes means for protecting the cladding against mechanical actions. Alternatively or additionally, this covering element has a particular color and / or particular patterns and / or is transparent or translucent.

[0011] According to another feature, the composite insulation panel has at least one border, on the one hand, extending from at least one lateral side of the vacuum insulation panel and in the continuation of said at least one lateral side of this vacuum insulation panel, on the other hand, which is made of an insulating material comprising an aerogel and, on the other hand still, which is configured to be cut.

[0012] Another characteristic relates to the fact that the composite insulation panel has at least one information area which includes information relating to whether or not the information area can be cut.

[0013] According to another feature, the composite insulation panel has at least one information area which includes information relating to whether or not the information area can be cut.

[0014] The invention also relates to a composite insulation system comprising, on the one hand, two juxtaposed composite insulation panels and, on the other hand, mounting means configured for mounting the two composite insulation panels onto a structural element of a building. This composite insulation system is characterized in that, on the one hand, the two composite insulation panels have at least some of the characteristics described above, and on the other hand, the mounting means comprise a support configured to be fixedly attached to the structural element, as well as fastening means configured for fixing the two composite insulation panels to said support, and Furthermore, the insulation system includes means of concealing these mounting means.

[0015] Finally, the invention relates to a method for manufacturing a composite insulation panel that has the characteristics mentioned above. This manufacturing method comprises, on the one hand, a step of preparing a mixture that contains at least jute and corn, on the other hand, a step of coating at least a part of one of the two large parallel faces of a vacuum insulation panel with the mixture, and on the other hand, a step of hardening the mixture.

[0016] Thus, the invention relates to a composite insulation panel which comprises, on the one hand, a vacuum insulation panel and, on the other hand, a coating which comprises a mixture which contains at least jute and corn.

[0017] Advantageously, such a composite insulation panel is directly ready for use, does not require additional intervention (such as the application of a joint, coating and / or cladding), and constitutes a so-called finishing solution.

[0018] Furthermore, the presence of jute in the mixture advantageously increases the thermal insulation performance of the composite insulation panel while also increasing its mechanical strength. Additionally, the presence of jute advantageously increases the acoustic performance (particularly sound attenuation) of the composite insulation panel. Moreover, the presence of jute advantageously provides the composite insulation panel with better resistance to mold and moisture, as well as to pests (particularly insects and / or spiders). Finally, the presence of jute advantageously allows the composite insulation panel to absorb certain toxins and carbon dioxide.

[0019] In addition, the composite insulation panel includes at least one edge made of an insulating material and configured to be cut. The presence of this edge advantageously allows a portion of the composite insulation panel to be cut to adjust its shape and dimensions to those of the structural element to be insulated, while maintaining high insulation performance.

[0020] Yet another characteristic concerns the fact that the composite insulation panel has at least one informational area containing information regarding whether or not the informational area is cuttable. This advantageously avoids cutting the vacuum insulation panel, which would lead to a loss of the insulation performance conferred by this vacuum insulation panel. This also allows, in the presence of a cuttable edge, for only this edge to be cut without damaging the vacuum insulation panel, while adjusting the shape and / or dimensions of the composite insulation panel to the element structural to be isolated and, thus, ensure optimal insulation of this structural element.

[0021] Other objects and advantages of the present invention will become apparent during the following description relating to embodiments which are given only by way of indicative and non-limiting examples.

[0022] Understanding this description will be facilitated by referring to the drawings attached in the appendix, in which:

[0023] [Fig. 1] represents a schematic and perspective view of a first embodiment of a composite insulation panel according to the invention.

[0024] [Fig.2] represents a schematic and perspective view of a second embodiment of a composite insulation panel according to the invention.

[0025] [Fig.3] represents a schematic and cutaway view of a third embodiment of a composite insulation panel according to the invention.

[0026] [Fig.4] represents a schematic and perspective view of a fourth embodiment of a composite insulation panel according to the invention.

[0027] With reference to the figures in the attached drawings, the present invention relates to the field of building, more particularly to the field of insulation of a building and, more specifically, to the field of manufacturing insulation devices for such a building, this from the inside of this building.

[0028] The invention relates, then, to a composite insulation panel 1 which comprises, on the one hand, a vacuum insulation panel 2 usually called “VIP”, which is an acronym for the Anglo-Saxon name “Vacuum Insulation Panel”.

[0029] Such a vacuum insulation panel 2 has two large parallel faces (20; 20') as well as lateral sides (21; 21').

[0030] Such a vacuum insulation panel 2 extends along a plane which is parallel to a plane along which extends one 20 or the other 20' of the two large parallel faces (20; 20').

[0031] According to another characteristic, such a vacuum insulation panel 2 has a thickness between 15mm and 25mm, preferably between 18mm and 22mm, in particular in the order of 20mm.

[0032] Yet another characteristic consists in the fact that the vacuum insulation panel 2 comprises, internally, glass fibers, on the one hand, which extend, each, along a plane which is parallel to the plane along which the vacuum insulation panel 2 extends and, on the other hand, which have a thickness (in particular a diameter) between 3 microns and 12 microns (more particularly between 6 microns and 9 microns) and a length between 2 centimeters and 12 centimeters (more particularly between 5 centimeters and 9 centimeters).

[0033] These glass fibers are arranged in the form of a plurality of glass fiber layers that are superimposed and parallel to the plane along which the insulation panel vacuum 2 extends.

[0034] These characteristics advantageously allow the vacuum insulation panel 2 to have a thermal conductivity / between 0.0005 W / (mK) and 0.0025 W / (mK), more particularly between 0.0010 W / (mK) and 0.0020 W / (mK), in particular of the order of 0.0015 W / (mK).

[0035] On the other hand, the composite insulation panel 1 has a coating 3 which covers at least a part of one 20 of the two large parallel faces (20; 20') of the vacuum insulation panel 2.

[0036] According to a preferred embodiment, this coating 3 covers the entirety of one 20 of the two large parallel faces (20; 20') of the vacuum insulation panel 2.

[0037] According to another feature, this coating 3 comprises a mixture which contains at least jute and at least corn.

[0038] In this regard, it will be noted that this mixture then contains at least jute fibers and / or at least corn fibers. According to a preferred embodiment, this mixture contains at least jute fibers and at least corn fibers.

[0039] The presence of corn (in particular corn fibers) advantageously allows the adhesion of plant fibers (in particular jute fibers) to each other and / or to the vacuum insulation panel 2.

[0040] According to another feature, the coating 3 contains at least, on the one hand, between 50% and 70% by mass of jute, more particularly of jute fibers and, on the other hand, between 30% and 50% by mass of corn, more particularly of corn fibers, so that the sum of the percentages is at most equal to 100%, preferably equal to 100%.

[0041] Preferably, the coating 3 contains at least, on the one hand, between 55% and 65% by mass of jute, more particularly of jute fibers and, on the other hand, between 35% and 45% by mass of corn, more particularly of corn fibers, so that the sum of the percentages is at most equal to 100%, preferably equal to 100%.

[0042] In particular, the coating 3 contains approximately 60% by mass of jute (more particularly jute fibers) and approximately 40% by mass of corn (more particularly corn fibers), so that the sum of the percentages is at most equal to 100%, preferably equal to 100%.

[0043] According to another characteristic, the coating 3 has a thickness between 2mm and 6mm, preferably between 3mm and 5mm, in particular on the order of 4mm.

[0044] Thus and as mentioned above, on the one hand, the vacuum insulation panel 2 can have a thickness of between 15mm and 25mm and, on the other hand, the coating 3 can have a thickness of between 2mm and 6mm.

[0045] These characteristics advantageously allow the insulation panel to be given composite 1 a thermal conductivity X between 0.0010 W / (mK) and 0.0030 W / (mK).

[0046] Preferably, the vacuum insulation panel 2 has a thickness of between 18mm and 22mm while the coating 3 has a thickness of between 3mm and 5mm.

[0047] These characteristics advantageously allow the composite insulation panel 1 to have a thermal conductivity X between 0.0015 W / (mK) and 0.0025 W / (mK).

[0048] In particular, on the one hand, the vacuum insulation panel 2 has a thickness of approximately 20mm and, on the other hand, the coating 3 has a thickness of approximately 4mm.

[0049] These characteristics advantageously allow the composite insulation panel 1 to have a thermal conductivity X of the order of 0.0020 W / (mK).

[0050] According to another feature, the coating 3 is bonded to the vacuum insulation panel 2

[0051] Yet another feature relates to the fact that the composite insulation panel 1 may include a covering element 4, on the one hand, which covers at least a part of the coating 3 (more particularly at least a part of the surface of this coating 3) and, on the other hand, which extends over at least a part of the coating 3 (more particularly over at least a part of the surface of this coating 3). Thus, the coating 3 is interposed between the vacuum insulation panel 2 and the covering element 4.

[0052] In particular, the cover element 4, on the one hand, covers the entire coating 3 (more particularly the entire surface of this coating 3), on the other hand, extends over the entire coating 3 (more particularly over the entire surface of this coating 3).

[0053] This cover element 4 then includes protective means configured to protect the coating 3 against mechanical actions (more particularly against scratches, impacts, or the like). These protective means may be, at least in part, made up of the material of this cover element 4.

[0054] Alternatively or (and preferably additionally), this cover element 4 has a particular colour and / or has particular patterns and / or is transparent or translucent.

[0055] These characteristics advantageously allow the composite insulation device 1 to have a particular appearance.

[0056] According to another feature, the cover element 4, on the one hand, comprises (preferably, is made of) a film, a sheet or a plate, on the other hand, has a thickness between 0.5mm and 2mm and, on the other hand, is made of a polymer material (preferably PVC or resin).

[0057] Additionally, the coating 3 and / or the cover element 4 may incorporate carbon particles, more particularly carbon beads.

[0058] These carbon particles advantageously allow the adsorption of odors, pollutants and contaminants, more particularly organic contaminants such as volatile organic compounds (VOCs).

[0059] According to another feature, the composite insulation panel 1 may include at least one edge 5, on the one hand, extending from at least one lateral side (21; 21') of the vacuum insulation panel (2) and in the continuation of said at least one lateral side (21; 21') of this vacuum insulation panel (2), on the other hand, which is made of an insulating material comprising an aerogel, and, on the other hand still, which is configured to be cut.

[0060] In this regard, it will be observed that the said insulating material is, then, at least in part (or even entirely) made up of an aerogel, more particularly one which includes aerogel fibers.

[0061] The use of such an aerogel advantageously allows for a smoother, simpler and more precise cutting.

[0062] Another characteristic is that the border 5 has a thickness that is substantially equal to that of the vacuum insulation panel 1. Thus, this border 5 has a thickness between 15mm and 25mm, preferably between 18mm and 22mm, in particular in the order of 20mm.

[0063] This border 5 then has a thermal conductivity X between 0.0010 W / (mK) and 0.0030 W / (mK), preferably between 0.0015 W / (mK) and 0.0025 W / (mK), in particular of the order of 0.0020 W / (mK).

[0064] It will be observed that the coating 3 mentioned above then covers at least part (or even all) of one 50 of the two parallel faces (50; 50') that comprise such a border 5 ([Fig.3]).

[0065] According to another feature, the composite insulation panel 1 may include at least one vapor barrier 6 which covers at least a part (or even all) of the large face 20' of the vacuum insulation panel 2 which is opposite the large face 20 of this vacuum insulation panel 2, at least a part of which is covered by the coating 3.

[0066] According to a particular embodiment, such a vapor barrier 6 can also cover at least part of at least one of the lateral sides (21; 21') of the vacuum insulation panel 2.

[0067] In an embodiment where the composite insulation panel 1 has at least one edge 5 ([Fig.4]), this composite insulation panel 1 may, further, include at least one 6' vapor barrier (more specifically another 6' vapor barrier than the one 6 mentioned above) which covers at least part (or even all) of said at least one 5' edge.

[0068] Such a vapor barrier 6 then covers at least part (or even all) of the face 50' of the edge 5 which is opposite the face 50 of the edge 5, at least part of which is covered by the coating 3.

[0069] Yet another characteristic relates to the fact that the composite insulation panel 1 has at least one information area (7; 7') which includes information relating to whether the information area (7; 7') can be cut or not.

[0070] In this regard, it will be observed that it is, more particularly, the said at least one vapor barrier (6; 6') mentioned above which has at least one information zone (7; 7') which includes information relating to the cross-sectional nature of the information zone (7; 7').

[0071] In particular, the vapor barrier 6 which covers at least part (or even all) of the large face 20' of the vacuum insulation panel 2 has at least one information zone 7 which includes information relating to the non-cuttable nature of the information zone 7 and, consequently, of the vacuum insulation panel 2 covered by this vapor barrier 6.

[0072] Similarly, the vapor barrier 6' which covers at least part (or even all) of the face 50' of the edge 5 has at least one information zone 7' which includes information relating to the cross-cutting nature of the information zone 7' and, consequently, of the edge 5 covered by this vapor barrier 6'.

[0073] The invention also relates to a composite insulation system which comprises, on the one hand, two composite insulation panels 1 which are juxtaposed and, on the other hand, mounting means which are configured to mount the two composite insulation panels 1 on a structural element of a building, more particularly on a wall, in particular on an external wall (more specifically on the internal face of such an external wall).

[0074] Such a composite insulation system is characterized by the fact that, on the one hand, the two composite insulation panels 1 have at least some of the characteristics described above, on the other hand, the mounting means comprise a support (more particularly in the form of a bar or similar) which is configured to be made fixedly attached to the structural element as well as fixing means (in particular in the form of hooks which equip the support, more particularly the bar) which are configured to fix the two composite insulation panels 1 to said support and, on the other hand, the insulation system comprises means for concealing these mounting means.

[0075] Such mounting means are then interposed between the two panels 1. Insulation composites.

[0076] As regards the concealing means, these may consist of a lip on the composite insulation panel 1 (more particularly the vacuum insulation panel 2 or the coating 3 on this composite insulation panel 1) and behind which the mounting means are concealed. Alternatively, such concealing means may take the form of an element (for example, a bar or a strip) positioned at the junction of the two composite insulation panels 1 and, as appropriate, above or between these two composite insulation panels 1.

[0077] Another characteristic relates to the fact that the composite insulation system may also include finishing means which are configured to equip at least one composite insulation panel 1 as mentioned above, this in the lower part, in the upper part or laterally.

[0078] Such finishing means can, then, constitute at least in part a baseboard, a top baseboard or a side edge which comprises such a composite insulation system.

[0079] Such finishing means may take the form of at least one bar.

[0080] Such finishing means may be made of aluminium and / or treated with a Insulating paint, particularly aerogel-based paint. These characteristics prevent the creation of a thermal bridge between a composite insulation panel 1 and, depending on the case, the floor, the ceiling or a corner of a structural element.

[0081] Finally, the present invention relates to a method for manufacturing a composite insulation panel 1 which has at least some of the characteristics described above.

[0082] This manufacturing process comprises, on the one hand, a step of producing a mixture which contains at least jute (more particularly jute fibers) and corn (more particularly corn fibers), on the other hand, a step of covering at least a part (more particularly the whole) of one 20 of the two large parallel faces (20; 20') of a vacuum insulation panel 2 with the mixture, on the other hand, a step of hardening the mixture.

[0083] According to a particular embodiment, the step of making the mixture consists of making a mixture which contains at least jute (more particularly jute fibers), corn (more particularly corn fibers) and a binder (more particularly water and / or a resin),

[0084] In this case, the hardening step consists of removing at least part of the binder (by extraction or by evaporation, in particular by heating) or allowing at least part of the binder to harden or causing at least part of the binder to harden (in particular by heating, by exposure to suitable light or otherwise).
