Description

Title of the invention: Thermal insulation module for the external thermal insulation of a building. Technical field of the invention

[0001] The present invention relates to the technical field of external thermal insulation of buildings.

[0002] The invention relates more specifically to a thermal insulation module for thermally insulating a building from the outside. Previous technique

[0003] The improvement of the energy performance of buildings has seen strong development in recent years.

[0004] It is known to thermally insulate buildings from the outside. Such insulation, known as EWI (External Wall Insulation), consists of installing panels of insulating material, such as mineral wool or polystyrene, on the building facades. The insulating panels are installed one after the other on the facade to be insulated and each fixed using either fasteners, such as screws, or adhesives. Once all the insulating panels are fixed to the facade, a reinforcing layer and then a finishing layer are applied directly to the exterior faces of the insulating panels.

[0005] This external insulation technique has the advantage, compared to internal insulation, of not impacting the living areas of the building because the extra thickness induced by the insulating material panels is created outside the building and not inside the building, while guaranteeing better thermal insulation due to the elimination of thermal bridges.

[0006] However, this external insulation technique proves to be relatively complex to implement, requires the mobilization of several operators on site, as well as substantial equipment such as scaffolding or a flying bridge, and requires a significant installation time. Presentation of the invention

[0007] The present invention aims to remedy the aforementioned drawbacks.

[0008] To this end, the present invention proposes a thermal insulation module for the external thermal insulation of a building, said thermal insulation module being intended to be positioned vertically and having an internal face, intended to be positioned opposite an external face of the building, and an external face, opposite the internal face, and comprising: - a multilayer structure, called core (10), having a rear face (101), on the inner face (501) side of the thermal insulation module (500), a front face (102), on the outer face (502) side of the thermal insulation module (500), and a peripheral edge (103),

[0009] said core comprising, from its rear face (101) to its front face (102), a stack of layers successively comprising: • a first layer (12a) of insulating material, • a support plate (11), • a second layer (12b) of insulating material,

[0010] said core being devoid, at the level of a part, called the upper part, of the thermal insulation module, of the first layer of insulating material, - a reinforcing layer covering the core at its front face and all or part of its peripheral edge, - a finishing layer covering the reinforcing layer.

[0011] The thermal insulation module further comprises at least one attachment element for fixing said thermal insulation module to the exterior face of the building, said at least one attachment element being arranged at the top of the thermal insulation module and being fixed to the support plate, preferably on the first face of the support plate.

[0012] Such a thermal insulation module has many advantages.

[0013] Such a thermal insulation module advantageously features, unlike thermal insulation modules of the prior art, directly a reinforcing layer and a finishing layer.

[0014] Such a thermal insulation module can advantageously be manufactured off-site and then transported to the site where the building to be insulated is located.

[0015] On site, once the thermal insulation modules are positioned on the exterior face of the building and fixed to said exterior face by the fastening elements, it is no longer necessary to apply an additional reinforcing layer and a finishing layer to the thermal insulation modules. The number of operators required on site to carry out the exterior insulation of the building is therefore considerably reduced, as is their intervention time on site.

[0016] In addition, the presence of the support plate in the module contributes advantageously to the overall rigidity of the thermal insulation module by forming a load-bearing structure for the two layers of insulating material.

[0017] According to particular embodiments, the invention also meets the following characteristics, implemented separately or in each of their technically operative combinations.

[0018] In particular embodiments, a fastening element is in the form of a bracket comprising: - a first branch intended to be fixed to the support plate, preferably on the first face of the support plate, - a second branch, extending from the first branch, and presenting at one free end, a drooping edge.

[0019] In particular embodiments, the two layers of insulating material may be made of different or identical materials.

[0020] Thus, it is possible to combine, in the same module, insulating materials with different thermal resistance coefficients, and different or the same thicknesses, to achieve the desired thermal performance or to meet the requirements relating to fire standards.

[0021] In particular embodiments, the two layers of insulating material are chosen from expanded polystyrene, rock wool, wood wool, or other bio-based material.

[0022] A “bio-based” material is obtained from an organic raw material, of animal or, preferably, plant origin.

[0023] In particular embodiments, the support plate is chosen from an OSB plate, a fiber cement plate.

[0024] In particular embodiments, to ensure long-term protection of the support plate against water infiltration into the thermal insulation module, the core includes a rain barrier film interposed between the support plate and the second layer of insulating material.

[0025] In particular embodiments, to ensure the rigidity of the support plate, the core comprises at least one stiffening element arranged between the support plate and the first layer of insulating material, said first layer of insulating material having at least one cavity, each cavity being intended for receiving a stiffening element.

[0026] The invention also relates to a covering kit comprising thermal insulation modules conforming to at least one of its embodiments and at least one guide rail, each guide rail being intended to be fixed to the exterior face of the building, the attachment elements of each thermal insulation module being intended to cooperate with a guide rail.

[0027] The invention also relates to a method of external thermal insulation of a building using a cladding kit conforming to at least one of its embodiments and comprising the steps of: - fixing a guide rail to an exterior face of the building, - positioning of the thermal insulation modules, previously made, on the guide rail, one after the other.

[0028] Such a method allows the exterior face of the building to be covered with thermal insulation modules, by positioning said thermal insulation modules side by side, leaving a gap between two adjacent thermal insulation modules. A joining profile can be placed between the thermal insulation modules to ensure a seal between said thermal insulation modules.

[0029] Such a method also makes it easier for operators to install the thermal insulation modules on site. The guide rail is fixed to the outer face, and then the thermal insulation modules are fixed to the guide rail.

[0030] The guide rail is preferably fixed with spacers to compensate for the unevenness of existing buildings.

[0031] Fixing the guide rail to the outside face and then installing the thermal insulation modules proves easier for operators on site than fixing the thermal insulation module itself to the outside face. Brief description of the figures

[0045] In these figures, identical numerical references from one figure to another designate identical or analogous elements. Furthermore, for reasons of clarity, the drawings are not to scale unless otherwise stated. Description of the implementation methods

[0046] Figures 1 to 12 show an example of a thermal insulation module 500 for thermally insulating a building 20 from the outside.

[0047] In the rest of the description, the thermal insulation module 500 will simply be referred to as the module.

[0048] In the rest of the description, also, when referring to absolute position qualifiers, such as the terms "high", "low", etc., or relative position qualifiers, such as the terms "higher", "lower", etc., or to orientation qualifiers, such as "horizontal", "vertical", etc., reference is made, unless otherwise specified, to the orientation of the module in its normal position of use.

[0049] To facilitate reading the figures, the module 500 will be associated with an orthonormal coordinate system XYZ. X designates a longitudinal axis of the module, Y designates an axis perpendicular to X, called the transverse axis, and Z designates an axis perpendicular to X and Y, called the vertical axis. Thus, the module 500 has a length along the X axis, a thickness along the Y axis, and a height along the Z axis.

[0050] Fig. 1 represents a module 500 positioned on an external face 22 of the building 20. The module 500 is intended to be positioned vertically against the external face 22 of the building 20.

[0051] The module 500 is intended to cover part of the outer face 22 of a building 20. More precisely, the outer face 22 of the building 20 corresponds to the outer face of an external wall 21 of the building 20.

[0052] Building 20 may, for example, be a dwelling house, without this being a limitation of the invention.

[0053] The module 500 has an inner face 501 intended to be positioned opposite the outer face 22 of the building 20. The module 500 has an outer face 502, opposite the inner face 501. The inner and outer faces 501, 502 of the module 500 are vertical when the module 500 is in its normal operating position. The module 500 has a peripheral edge 503 extending between the inner face 501 and the outer face 502.

[0054] In the non-limiting example illustrated in [Fig. 1], the module 500 has a general parallelepiped shape. The internal and external faces 501, 502 of the module 500 are parallel to each other. The peripheral edge 503 is formed by two edges, referred to as horizontal, and two edges, referred to as vertical.

[0055] Module 500 comprises a multilayer structure, referred to as core 10, illustrated in Figures 3 and 4.

[0056] The core 10 has a so-called rear face 101, a so-called front face 102, and a peripheral edge 103. The rear face 101 is located on the side of the inner face 501 of the module 500. The front face 102 is located on the side of the outer face 502 of the module 500.

[0057] The core 10 comprises a stack of successive layers.

[0058] The core 10 includes a support plate 11.

[0059] The support plate 11 comprises a first face 111 and a second, opposite face 112. The support plate 11 has a peripheral edge 113 extending between the first face 111 and the second face 112. The support plate 11 preferably has a constant thickness. The first face 111 is located on the side of the inner face 501 of the module 500. The second face 112 is located on the side of the outer face 502 of the module 500.

[0060] In a preferred embodiment, the support plate 11 can be a panel generally designated by the English acronym OSB for "Oriented Strand Board". For example, panels commercially known as OSB3 can be used.

[0061] In another embodiment, the support plate 11 can be a fiber cement plate.

[0062] The core 10 further comprises two layers 12a, 12b of insulating material arranged on either side of the support plate 11. A first layer 12a of insulating material is arranged at the first face 111 of the support plate 11. A second layer 12b of insulating material is arranged at the second face 112 of the support plate 11.

[0063] In other words, the core 10 comprises, from its rear face 101 to its front face 102, a stack of layers successively comprising: - the first layer 12a of insulating material, - the support plate 11, - the second layer 12b of insulating material.

[0064] The first layer 12a of insulating material has a first face 121a forming the rear face 101 of the core. The first layer 12a of insulating material has a second face 122a intended to face the first face 111 of the support plate 11. The first layer 12a of insulating material has a peripheral chant 123a extending between its first face 121a and its second face 122a.

[0065] The second layer 12b of insulating material has a first face 121b intended to face the second face 112 of the support plate 11. The first layer 12a of insulating material has a second face 122b forming the front face 102 of the core 10. The second layer 12b of insulating material has a peripheral edge 123b extending between its first face 121b and its second face 122b.

[0066] The support plate 11 advantageously forms a load-bearing structure for the two layers 12a, 12b of insulating material and thus contributes to the final rigidity of the module 500.

[0067] The second layer 12b of insulating material is dimensioned to cover the second face 112 of the support plate 11. By cover, it is understood that the dimensions, in length and height, of the second layer 12b of insulating material are substantially identical to those of the support plate 11. The second layer 12b of insulating material preferably has a constant thickness.

[0068] The first layer 12a of insulating material is dimensioned to partially cover the first face 111 of the support plate 11. More precisely, the first layer 12a of insulating material covers the first face 111 of the support plate 11, except at the level of an upper part 505 of the module 500.

[0069] By upper part, we mean an upper part of the module 500 when said module is in its normal position of use, i.e. in vertical position.

[0070] The core 10 is thus devoid, at the level of the upper part 505 of the module 500, of the first layer 12a of insulating material, as illustrated in figures 3 and 4.

[0071] The first layer 12a of insulating material thus has a length dimension substantially identical to that of the support plate 11 and a height dimension less than that of the support plate 11. The first layer 12a of insulating material preferably has a constant thickness.

[0072] Preferably, the core 10 is devoid, at the level of the upper part 505 of the module 500, of the first layer 12a of insulating material, over a band of height of about ten centimeters.

[0073] It is clear from the description that the peripheral edge 113 of the support plate 11 is not covered by any layer of insulating material.

[0074] Preferably, the two layers 12a, 12b of insulating material are assembled respectively on each of the faces 111, 112 of the support plate 11 by doweling.

[0075] In one embodiment, the two layers 12a, 12b of insulating material can be made of different materials.

[0076] In preferred embodiments, the two layers 12a, 12b of insulating material can be made of expanded polystyrene (EPS), rock wool, wood wool or other bio-based material....

[0077] The thickness and type of each of the two layers of insulating material depends on the fire regulations and the thermal requirements of the building, knowing that the thermal resistance coefficients (R) of each layer of insulating material add up advantageously.

[0078] In other words, the front face 102 of the core 10 corresponds to the second face 122b of the second layer 12b of insulating material. The rear face 101 of the core 10 corresponds to the first face 121a of the first layer 12a of insulating material and, at the top, to the first face 111 of the support plate 11. The peripheral edge 103 of the core 10 corresponds to: - at the peripheral edge 113 of the support plate 11, - at the peripheral edge 123a of the first layer 12a of insulating material 11, and, - to the peripheral edge 123b of the second layer 12b of insulating material.

[0079] The module 500 further comprises a reinforcing layer 13, as illustrated in Figures 5 and 6.

[0080] Fig. 5 illustrates a cross-section of module 500 at mid-height of the module and Fig. 6 illustrates a cross-section of module 500 at the level of the upper part 505 of the module.

[0081] The reinforcing layer 13 is intended to be applied to the core 10, covering its front face 102 and all or part of its peripheral edge 103. The reinforcing layer 13 is advantageously configured to reinforce and protect the module 500.

[0082] Preferably, the reinforcing layer 13 covers at least the peripheral edge 113 of the support plate 11 and the peripheral edge 123b of the second layer 12b of insulating material. The reinforcing layer 13 may cover the peripheral edge 123a of the first layer 12a of insulating material 11, except at the top 505 of the module. More specifically, the reinforcing layer 13 may cover both vertical edges and the lower horizontal edge of the second layer 12b of insulating material, but does not cover the upper horizontal edge of the second layer 12b of insulating material.

[0083] In an alternative embodiment, the reinforcing layer 13 can also cover all or part of the rear face 101 of the core 10.

[0084] In a preferred embodiment (not shown in the figures), the reinforcing layer 13 may comprise a mesh embedded in two layers of coating. The mesh may consist of reinforcing fibers, such as, for example, glass fibers, extending in different directions. The two layers of coating can each consist of a coating resin or any other suitable coating.

[0085] The module 500 further comprises a finishing layer 14. The finishing layer 14 is advantageously configured to provide an aesthetic final appearance to said module.

[0086] The finishing layer 14 is intended to be applied over the reinforcing layer 13. The finishing layer 14 covers the reinforcing layer 13. By covering the reinforcing layer, it is understood that the finishing layer 14 is deposited only on the reinforcing layer 13. Once the finishing layer 14 has been applied, the reinforcing layer 13 is no longer visible.

[0087] The finishing layer 14 is advantageously made of any suitable material to give the module 500 the desired external appearance.

[0088] In preferred embodiments, the topcoat 14 may be one or more superimposed layers of a thick plastic coating (RPE), a thick mineral coating (RME), a paint or other.

[0089] In other words, module 500 is defined as follows: - its external face 502 corresponds to the front face 102 of the core 10 covered by the reinforcing layer 13 and the finishing layer 14, - its inner face 501 corresponds to the rear face 101 of the core 10, - its peripheral edge 503 corresponds to the peripheral edge 103 of the core 10 covered in whole or in part by the reinforcement layer 13 and the finishing layer 14.

[0090] In one embodiment (not shown), the core 10 may include, between the support plate 11 and the second layer 12b of insulating material, a rainscreen. The rainscreen is sized to cover the second face 112 of the support plate 11. The rainscreen is advantageously intended to protect the support plate 11 from water that may have infiltrated the module 500 from its external face 502. The rainscreen is recommended, or even necessary, when the support plate 11 is an OSB3 board. In general, the rainscreen is recommended when the material constituting the support plate 11 has its properties affected by contact with water.

[0091] The rainscreen film is assembled to the support plate 11 preferably by stapling.

[0092] In one embodiment (not shown), the core 10 may include a or several stiffening elements arranged between the support plate 11 and the first layer 12a of insulating material. Depending on the module's dimensions, the stiffening element(s) advantageously stiffen the support plate 11 and thus limit its buckling. The stiffening element(s) extend vertically through the height of the module 500, meaning they extend vertically when the module is in its normal operating position.

[0093] The number of stiffening elements depends on the dimension of the 500 module.

[0094] The first layer 12a of insulating material may include one or more cavities, each cavity being intended to receive a stiffening element. Preferably, each cavity has a shape complementary to a stiffening element. Each cavity is formed in the first layer 12a of insulating material, from the second face 122a. Thus, each stiffening element is surrounded by the first layer 12a of insulating material.

[0095] The module 500 further comprises one or more attachment element(s) 15 configured to allow the attachment of said module to the outer face 22 of the building 22, as illustrated in Figures 7, 9 to 12.

[0096] Each attachment element 15 is preferably intended to cooperate with a guide rail 30 fixed to the outer face 22 of the building 20.

[0097] Each hooking element 15 is arranged at the upper part 505 of the module 500. More precisely, each hooking element 15 is arranged in the space devoid of the first layer 12a of insulating material.

[0098] Each attachment element 15 is fixed to the support plate 11. Preferably, each attachment element is fixed to the first face 111 of the support plate 11.

[0099] In one embodiment, as illustrated in [Fig. 10], a hanging element 15 is in the form of a bracket.

[0100] The set square 15 features: - a first branch 151 intended to be fixed to the support plate 11, preferably on the first face 111 of the support plate, - a second arm 152 extending from the first arm 151.

[0101] The second arm is substantially perpendicular to the first arm 151. The second arm 152 has, at one free end 155, a dropped edge 153.

[0102] The bracket 15 is fixed to the support plate 11 by at least one fastener 16, as illustrated in [Fig. 9]. A fastener 16 is, for example, a screw or a bolt. The first arm 151 preferably has at least one through hole 154 for the passage of a fastener 16.

[0103] In the non-limiting example of [Fig. 10], the first branch 151 has two through holes 154, each of said through holes being configured to receive the passage of a fastening element 16.

[0104] The second arm 152 of the bracket 15 preferably has a length (dimension along the Y-axis) substantially greater than the total thickness of the first layer 12a of insulating material, the finishing layer 13 and the finishing layer 14 so that when the module 500 is placed on the outer face 22 of the building 20, the inner face 501 of the module 500 is slightly spaced from the outer face 22 of building 20, as illustrated in [Fig.9]. This space created between the inner face 501 of module 500 and the outer face 22 of building 20 advantageously compensates for the flatness defects of the existing buildings.

[0105] In one embodiment, the attachment element 15 is made of a metallic material, such as stainless steel or aluminum.

[0106] Preferably, the attachment element 15 is fixed to the support plate 11, prior to the application of the reinforcement layers 13 and coating 14. In the example of an attachment element 15 in the form of a bracket, the first arm 115 is then not visible.

[0107] As described previously, the module 500 is assembled on the outer face 22 of the building 20, in association with a guide rail 30 fixed to said outer face 22 of the building.

[0108] The guide rail 30 preferably takes the form of a longitudinal profile, for example with a square or rectangular cross-section. The longitudinal profile may be hollow or solid. In the example illustrated in [Fig. 9], without limiting the invention, the guide rail 30 takes the form of a hollow profile with a rectangular cross-section.

[0109] The guide rail 30 is intended to be fixed to the outer face 22 of the building 20, along the X axis. In other words, the guide rail 30 is fixed horizontally to the outer face 22 of the building 20, as illustrated in Figures 1 and 2. The guide rail 30 is preferably dimensioned to receive several modules 500 placed side by side.

[0110] The guide rail 30 is fixed to the outer face 22 of the building 20 by means of fixing devices 31, as illustrated in figures 2 and 9, such as for example screws.

[0111] The guide rail 30 is preferably fixed to the outer face 22 of the building 20 with spacers so as to create a gap between the outer face 22 of the building 20 and the guide rail 30. This gap allows the dropped edge 153 of each bracket 15 to be received, as illustrated in [Fig. 9]. It also serves to compensate for any horizontal flatness defects in the outer faces 22 of existing buildings.

[0112] The bracket 15 is fixed to the guide rail 30 by at least one fastener (not shown in the figures), for example, a screw. The second arm 152 preferably has at least one through hole 154 for the passage of a fastener. In the non-limiting example of [Fig. 10], the second arm 152 has a through hole 154.

[0113] In one embodiment, to adjust the verticality of the module 500 on the outer face 22 of the building 20, shims 40 are arranged between the module and the outer face 22 of the building 20. The shims 40 are preferably located at the lower part of module 500, as illustrated in [Fig.8]. By lower part, we mean a lower part of module 500 when said module is in its normal operating position.

[0114] Each shim 40 has a thickness, different or not, which is a function of the out-of-plumbness of the outer face 22 of the building 20.

[0115] In a preferred embodiment, the shims 40 are adhesive pads or strips.

[0116] The adhesive pads or strips advantageously serve a dual purpose. In addition to their function of managing the out-of-plumb of the exterior face of the building, they also advantageously allow the module 500 to be glued against the exterior face 22 of the building 20 and thus guarantee that the module 500 remains in position on the exterior face 22 of the building 20.

[0117] The adhesive pads or strips can be, for example, adhesive mortar.

[0118] The 500 modules according to the invention are intended to be positioned one after the other the others on the outer face 22 of building 20, in rows, and joined together at one of their vertical edges, leaving a gap between the two vertical edges, until they cover the outer face 22 of building 20.

[0119] The dimensions of the modules depend on the dimensions of the exterior face of the building and the associated layout.

[0120] Preferably, the modules have a height on the order of one story height.

[0121] In one embodiment, the module 500 comprises, on one of the two edges For vertical modules, a joining piece extends along all or part of the vertical edge. Preferably, the joining piece extends along the entire vertical edge. Such a joining piece advantageously fills the vertical gap between two vertical edges of two adjoining modules and ensures a watertight seal between said two modules.

[0122] In a non-limiting embodiment, the joining piece comprises a foam strip extending between the two vertical edges of two adjoining modules. A sealing gasket covers the foam strip. The foam strip is, for example, a flexible polyurethane foam strip, such as the one known as "Compriband"®. The sealing gasket is, for example, a silicone gasket.

[0123] In another non-limiting embodiment, the joining piece is a joining profile which extends from a vertical edge of one of the two adjoining modules and which has a tab which bears against the external face of the other module, when the module is in position on the external face of the building.

[0124] Figures 1 to 12 illustrate a module 500 having a general parallelepiped shape. Alternatively, the module 500 may have a general shape in A horizontal L shape, to cover a salient angle formed by two external faces of a building, with each arm of the L covering one of the two external faces.

[0125] Several modules 500 and one or more guide rails 15 together form a covering kit to advantageously cover an exterior face 22 of a building 20.

[0126] A method for thermally insulating an external face 22 of a building 20 using the covering kit is now described.

[0127] The 500 modules are advantageously pre-manufactured off-site and then transported to the site where the building to be insulated is located.

[0128] The method includes a first step of fixing a guide rail 30 on the outer face 22 of the building 20.

[0129] The guide rail is intended to receive a plurality of 500 modules.

[0130] In one embodiment, the guide rail 30 is fixed horizontally to the outer face 22 of the building 20, at a height corresponding to the positioning of the upper part 505 of the modules 500. The guide rail 30 is fixed to the outer face 22 of the building 20 by means of the fixing members 31.

[0131] In a second step, the 500 modules are positioned one after the other on the guide rail.

[0132] In one embodiment, a first module is positioned. The first module is arranged with its inner face 501 opposite the outer face 22 of the building 20 and placed on the guide rail via each of its attachment elements 15. When an attachment element 15 is a bracket, the first module is placed on the guide rail 30 so that the dropped edge 153 of the second arm 150 of the bracket 15 is inserted into the space between the outer face 22 of the building 20 and the guide rail 30. The verticality of the module is then adjusted using the shims 40. The first module 500 is then fixed to the guide rail 30 via at least one fixing element.

[0133] A second module is then positioned on the guide rail. The second module is arranged with its inner face 501 opposite the outer face 22 of the building 20 and placed on the guide rail via each of its attachment elements 15, while being attached to the first module. A vertical edge of the second module is positioned near a vertical edge of the first module. The second module is fixed in the same manner as the first module.

[0134] Other modules are then positioned on the guide rail, attached to the previously installed module. All modules are fixed in the same manner as the first module. The modules are thus arranged in a single row.

[0135] Depending on the height of the modules and the exterior face of the building to be covered, it may be necessary to position modules on one or more additional rows. until the entire exterior face 22 of the building is covered. A guide rail 30 is fixed to the exterior face 22 of the building 20 to arrange the modules on each row.

[0136] The installed modules together form external thermal insulation for the building's exterior face. Since the modules according to the invention directly incorporate the reinforcement layer and the finishing layer, unlike existing modules, it is no longer necessary to apply a reinforcement layer and a finishing layer after their installation on the building's exterior face. The number of operators on site and the duration of their presence are thus advantageously reduced.
