Description

ELEMENT DE MODENATURE POUR SYSTEME D'ISOLATION THERMIQUE DES FAÇADES PAR L'EXTERIEUR, SON PROCEDE DE FABRICATION, SYSTEME D'ISOLATION ET SON PROCEDE DE REALISATION Domaine technique  MODENATURE ELEMENT FOR OUTDOOR THERMAL INSULATION SYSTEM, MANUFACTURING METHOD THEREFOR, INSULATION SYSTEM AND METHOD FOR PRODUCING THE SAME
Le domaine technique de l'invention est celui de l'isolation thermique des façades par l'extérieur. The technical field of the invention is that of the thermal insulation of facades from the outside.
La présente invention concerne un élément de modénature pour un système d'isolation thermique des façades par l'extérieur, comprenant un matériau thermiquement isolant et incombustible. La présente invention vise à apporter un aspect esthétique à un système d'isolation thermique par l'extérieur conforme à la réglementation incendie des bâtiments. Arrière-plan technologique  The present invention relates to a modenature element for a thermal insulation system of the facades from the outside, comprising a thermally insulating and non-combustible material. The present invention aims to provide an aesthetic appearance to a thermal insulation system from the outside in accordance with the building fire regulations. Technological background
Les systèmes d'isolation thermique par l'extérieur (appelés ETICS pour « External Thermal Insulation Composite System ») sont classiquement des panneaux isolants en polystyrène expansé recouverts d'un sous-enduit mince armé et revêtu d'un revêtement peinture épais (RPE). Ce complexe est collé ou calé/chevillé sur la paroi et assure l'isolation thermique, l'étanchéité et l'esthétique d'ensemble. Le but d'un système ETICS est d'éliminer les pertes de chaleur au niveau des façades et de créer ainsi une « enveloppe » assurant une continuité de l'isolation, une protection efficace contre la fissuration des enduits en accentuant l'étanchéité des matériaux de façades et en conservant des propriétés pertinentes dans le domaine des échanges gazeux. Exterior Thermal Insulation Composite Systems (ETICS) are classically expanded polystyrene insulation panels covered with a thin reinforced undercoat and coated with a thick paint coating (RPE) . This complex is glued or wedged / pegged on the wall and provides thermal insulation, watertightness and overall aesthetics. The goal of an ETICS system is to eliminate the heat losses at the facades and thus create an "envelope" ensuring a continuity of the insulation, an effective protection against the cracking of the coatings by accentuating the waterproofness of the materials facades and retaining properties relevant in the field of gas exchange.
De par la nature combustible du polystyrène classiquement utilisé pour l'isolation des façades ETICS, la réglementation incendie impose un certain nombre d'exigences à remplir (Instruction technique N°249 relative aux façades), notamment par l'application de la solution de protection par bandes filantes, afin d'éviter la propagation du feu par les façades. Les bandes filantes sont des bandes de protection horizontales situées au-dessus de chaque ouverture de la façade, composées d'un isolant en laine minérale de roche. Ces bandes d'épaisseur identique à celle des panneaux isolants recouvrant la façade sont collées sur sa surface et fixées mécaniquement à mi-hauteur de la bande. Pour éviter un risque de fissuration de l'enduit, à la jonction entre la bande filante et le polystyrène expansé, il convient de mettre en œuvre en complément une armature en fibres de verre débordant de part et d'autre de la bande sur le polystyrène expansé. La réglementation incendie impose donc des exigences précises pour la réalisation des façades ETICS, ces mêmes règles n'étant pas forcément compatibles avec l'aspect esthétique de l'architecture du bâtiment. En effet, il est imposé que sur une façade comportant des bandes filantes horizontales, des profilés décoratifs ne doivent pas être posés au-dessus de ces bandes filantes, sauf s'ils présentent une Euroclasse au moins A2- s3, dO selon la norme NF EN 13501-1. Due to the combustible nature of polystyrene conventionally used for the insulation of ETICS facades, the fire regulations impose a certain number of requirements to be fulfilled (Technical Instruction N ° 249 relating to façades), in particular by the application of the protective solution in stripes, to prevent the spread of fire through the facades. Strips are horizontal protection strips above each opening in the façade, made of rock mineral wool insulation. These strips of thickness identical to that of the insulating panels covering the facade are glued on its surface and mechanically fixed at mid-height of the strip. To avoid a risk of cracking of the coating, at the junction between the strip and the expanded polystyrene, it is necessary to implement in addition a fiberglass reinforcement flanking on both sides of the strip on the polystyrene expanded. The fire regulations therefore impose specific requirements for the realization of ETICS façades, these same rules not necessarily being compatible with the aesthetic aspect of the building's architecture. Indeed, it is imposed that on a facade comprising horizontal stripes, decorative profiles should not be placed above these strips, unless they have a Euroclass at least A2- s3, dO according to the NF standard EN 13501-1.
Les profilés décoratifs sont des éléments d'ornementation destinés à être rapportés sur une surface telle qu'une façade, pour former des reliefs tels que des bandeaux, des encadrements, des plinthes, etc. (autrement appelés « éléments de modénature »). Par « profilé », on entend un élément de forme allongée, et à profil constant.  Decorative profiles are ornamental elements intended to be attached to a surface such as a facade, to form reliefs such as bands, frames, baseboards, etc. (otherwise called "modenature elements"). "Profile" means an elongated element, and constant profile.
Classiquement, les éléments de modénature sont des profilés légers en polystyrène expansé qui sont collés ou calé/chevillés sur les supports, puis revêtus d'une peinture/enduit. Les éléments de modénature ne sont pas considérés comme des éléments de structure, c'est-à-dire que c'est leur support isolant qui assure par lui-même la fonction d'isolation et d'étanchéité. Par exemple, la demande de brevet FR2859131 Al décrit un élément de modénature comprenant une âme en polystyrène ou polyuréthane expansé, recouverte d'un enduit, et comprenant une grille ou une toile emprisonnée dans l'épaisseur d'une partie de l'âme et/ou du revêtement, assurant la pérennité de l'ensemble. Ce type d'élément de modénature présente l'inconvénient d'être réalisé dans un matériau combustible.  Conventionally, the molding elements are light expanded polystyrene profiles which are glued or wedged / pegged on the supports, then coated with a paint / coating. The elements of modénature are not regarded as elements of structure, that is to say that it is their insulating support which ensures by itself the function of insulation and sealing. For example, the patent application FR2859131 A1 discloses a molding element comprising a core of expanded polystyrene or polyurethane, covered with a coating, and comprising a grid or a cloth trapped in the thickness of a portion of the core and / or coating, ensuring the durability of the whole. This type of modenature element has the disadvantage of being made of a combustible material.
Il existe donc un réel besoin à ce jour, de disposer d'un élément de modénature du type profilé qui soit en matière incombustible, de façon à venir se substituer partiellement ou totalement aux bandes filantes tout en apportant un aspect esthétique et en contribuant à l'isolation thermique des façades. There is therefore a real need to date, to have a profiled element of the type profiled that is incombustible material, so as to come to replace partially or completely the stripes while providing an aesthetic appearance and contributing to the thermal insulation of facades.
Problème technique - Objectifs de l'invention Dans ce contexte, le problème technique à la source de la présente invention est de satisfaire à au moins l'un des objectifs énoncés ci-après : TECHNICAL PROBLEM - OBJECTIVES OF THE INVENTION In this context, the technical problem at the source of the present invention is to satisfy at least one of the objectives set out below:

Le noyau a.. The kernel has ..
Avantageusement, le matériau thermiquement isolant et incombustible a une conductivité thermique inférieure à 0.065 W/m.K et présente une Euroclasse Al selon la norme NF EN 13501-1, ledit matériau étant de préférence choisi dans le groupe comprenant- idéalement constitue par-: mousses minérales, mousse de béton, mousse de mortier, mousse de verre, laine de verre, laine de roche, perlite, aerogel de silice, wolastonite, vermiculite, plâtre, Staff, leurs combinaisons et les composites réalisés à partir desdits matériaux ; la laine de roche conforme à la norme NF EN 13162 étant particulièrement préférée. Avantageusement, le matériau présente également tout ou partie des caractéristiques techniques propres aux matériaux isolants, à savoir : Advantageously, the thermally insulating and incombustible material has a thermal conductivity of less than 0.065 W / mK and has a Euroclass A1 according to the standard NF EN 13501-1, said material preferably being chosen from the group consisting of- ideally constituted by: mineral foams , concrete foam, mortar foam, foam glass, glass wool, rockwool, perlite, silica aerogel, wolastonite, vermiculite, plaster, Staff, their combinations and composites made from said materials; stone wool conforming to standard NF EN 13162 being particularly preferred. Advantageously, the material also has all or part of the specific characteristics of the insulating materials, namely:
- une tolérance d'épaisseur selon la norme NF EN 823 égale à T5 ;  a tolerance of thickness according to standard NF EN 823 equal to T5;
- une résistance à la compression selon la norme NF EN 826 inférieure ou égale à 30 ;  - a compressive strength according to standard NF EN 826 less than or equal to 30;
- une stabilité dimensionnelle dans des conditions de température et d'humidité spécifiées dans la norme NF EN 1604 égale à DS (TH) ;  dimensional stability under temperature and humidity conditions specified in standard NF EN 1604 equal to DS (TH);
- une résistance à la traction perpendiculaire aux faces selon la norme NF EN 1607, TR inférieure ou égale à 10 ;  a tensile strength perpendicular to the faces according to standard NF EN 1607, TR less than or equal to 10;
- une absorption d'eau à court terme par immersion partielle selon la norme NF EN 1609 égale à WS.  - A short-term water absorption by partial immersion according to standard NF EN 1609 equal to WS.
Le choix du matériau constituant le noyau a. est important car il doit permettre une utilisation de l'élément de modénature en façade extérieure, sans que ses caractéristiques techniques soient affectées par des contraintes météorologiques significatives : exposition aux intempéries, températures élevées en été, fortes variations de chaleur, tout en remplissant son rôle de matériau incombustible pour éviter la propagation du feu. The choice of material constituting the core a. is important because it must allow a use of the element of modénature in external facade, without its technical characteristics are affected by significant meteorological constraints: exposure to bad weather, high temperatures in summer, strong variations of heat, while fulfilling its role of incombustible material to prevent the spread of fire.
De façon préférée, le noyau a. a une masse volumique unique, ladite masse volumique, exprimée en kg/m étant comprise dans les intervalles suivants donnés dans un ordre croissant de préférence : [10 - 1000] ; [20 -800] ; [30 - 600] ; [40 - 500] ; [50 - 400] ; [60- 300] ; [80 - 200]. Preferably, the nucleus a. has a single density, said density, expressed in kg / m being included in the following intervals given in increasing order of preference: [10-1000]; [20-800]; [30 - 600]; [40 - 500]; [50-400]; [60-300]; [80 - 200].
Par matériau ayant une masse volumique unique, on entend un matériau constitué d'une seule et unique couche de masse volumique égale dans tout le volume du matériau, par opposition aux matériaux bi-densité présentant deux couches de matériaux de masses volumiques différentes.  By material having a single density is meant a material consisting of a single and a single layer of density equal throughout the volume of the material, as opposed to bi-density materials having two layers of materials of different densities.
Une laine de roche de masse volumique relativement élevée est particulièrement adaptée à la réalisation du procédé selon l'invention, car une masse volumique faible peut engendrer des difficultés pour le manipulateur au moment de la découpe et de l'application de la couche de revêtement. De façon remarquable, le noyau est obtenu par usinage d'un bloc du matériau thermiquement isolant et incombustible. L'élément de modénature selon l'invention peut présenter diverses formes en fonction de l'effet esthétique recherché, tout en répondant aux exigences imposées par la réglementation incendie. Rock wool of relatively high density is particularly suitable for carrying out the method according to the invention, because a low density can cause difficulties for the manipulator at the time of cutting and the application of the coating layer. Remarkably, the core is obtained by machining a block of thermally insulating and incombustible material. The molding element according to the invention can present various forms depending on the aesthetic effect sought, while meeting the requirements imposed by fire regulations.
En outre, selon un mode de réalisation préféré de l'invention, le noyau est un profilé. Dans ce cas, l'élément de modénature pourra être destiné à un appui de fenêtre, ou à un encadrement de portes et fenêtres.  In addition, according to a preferred embodiment of the invention, the core is a profile. In this case, the modenature element may be intended for a window sill, or a frame of doors and windows.
Avantageusement, l'élément de modénature est esthétique et ornemental.  Advantageously, the element of modeling is aesthetic and ornamental.
Le revêtement. b._ et_ la couche . de finition c. The coating. b._ and_ the layer. finishing c.
Conformément à l'invention, le noyau est muni d'un revêtement b. au moins sur le côté destiné à rester en vue une fois posé l'élément sur la façade. Ce revêtement peut être réalisé en une ou plusieurs couches, identiques ou différentes, le nombre et/ou l'épaisseur et/ou le type de couches pouvant également varier selon les endroits. Il peut par exemple être intéressant de revêtir d'abord le noyau d'une ou plusieurs couche(s) d'un premier revêtement destiné à conférer au noyau de bonnes propriétés de résistance à la fissuration et de souplesse, puis d'une ou plusieurs couche(s) d'un deuxième enduit dit « de lissage » ou d'une peinture, faisant office de couche de finition c. pour conférer un aspect esthétique et homogène avec l'ensemble de la façade. According to the invention, the core is provided with a coating b. at least on the side intended to stay in sight once the element is placed on the facade. This coating may be made in one or more layers, identical or different, the number and / or the thickness and / or the type of layers may also vary depending on the location. For example, it may be advantageous to first coat the core of one or more layers with a first coating intended to give the core good properties of resistance to cracking and flexibility, then one or more layer (s) of a second so-called "smoothing" coating or paint, serving as a topcoat c. to give an aesthetic and homogeneous appearance with the whole of the facade.
Selon un mode de réalisation préféré de l'invention, le revêtement b. est renforcé par une armature, qui est de préférence un treillis en fibres de verre, fibres polypropylène, fibres polyamide, ou fibres de carbone, et de manière plus générale, toute armature ayant fait l'objet d'un certificat CSTBat délivré par Centre Scientifique et Technique du Bâtiment. Cette armature peut être marouflée dans un enduit colle. L'utilisation d'une armature sous le revêtement assure la stabilité dans le temps de la finition car il permet de compenser les variations dimensionnelles du support, dues aux conditions climatiques. According to a preferred embodiment of the invention, the coating b. is reinforced by an armature, which is preferably a fiberglass mesh, polypropylene fibers, polyamide fibers, or carbon fibers, and more generally, any armature having been the subject of a CSTBat certificate issued by Scientific Center and Building Technology. This frame can be stuck in a glue coating. The use of a reinforcement under the coating ensures the stability in the time of the finish because it makes it possible to compensate the dimensional variations of the support, due to the climatic conditions.
Le ou les revêtements utilisés peuvent être choisis parmi les enduits couramment utilisés dans les systèmes d'isolation thermique des façades par l'extérieur. En particulier, le revêtement est choisi dans le groupe comprenant -idéalement constitué par- : un enduit de type acrylique en pâte prête à l'emploi, un enduit de type vinylique en pâte prête à l'emploi, un mortier colle minéral à mélanger avec de l'eau, un enduit acrylique en pâte à mélanger avec du ciment. Les revêtements doivent être faciles à travailler, faciles à lisser et/ou présenter une bonne résistance à la fissuration. Selon les propriétés recherchées, ils peuvent comprendre en outre des fibres telles que des fibres cellulosiques, des fibres polyamide, des fibres polypropylène, des fibres de verre, des fibres de basalte, des charges minérales telles que des charges de carbonate de calcium, des charges siliceuses, des charges silico-aluminate, des oxydes d'alumine, des charges de terre diatomée, des talcs, ou des micas, des produits issus des résines siloxanes, des silicates, des liants organiques tels que des polymères acryliques, des polymères vinyliques, des résines époxy, ou des résines polyuréthannes , des adjuvants spécifiques tels que des additifs rhéologiques du type épaississants cellulosiques, acryliques, polyuréthannes, ou base d'argile modifiée, des agents de mouillage, des agents de protection biocides, des agents antimousse, des agents régulateurs de pH, des dispersants, des pigments tels que le dioxyde de titane, les oxydes de fer, des agents retardateurs de feu tels que le trihydrate d'alumine, etc. The coating or coatings used may be chosen from the coatings commonly used in the thermal insulation systems of facades from the outside. In particular, the coating is selected from the group consisting of-ideally constituted by: a ready-to-use paste type acrylic coating, a ready-to-use paste vinyl type coating, a mineral adhesive mortar to be mixed with water, an acrylic paste paste to mix with cement. The coatings must be easy to work, easy to smooth and / or have good resistance to cracking. Depending on the desired properties, they may further comprise fibers such as cellulosic fibers, polyamide fibers, polypropylene fibers, glass fibers, basalt fibers, mineral fillers such as calcium carbonate fillers, fillers and the like. siliceous fillers, silico-aluminate fillers, alumina oxides, diatomaceous earth fillers, talcs, or micas, products derived from siloxane resins, silicates, organic binders such as acrylic polymers, vinyl polymers, epoxy resins, or polyurethane resins, specific additives such as rheological additives such as cellulose, acrylic, polyurethane thickeners, or modified clay base, wetting agents, biocidal agents, antifoam agents, pH regulators, dispersants, pigments such as titanium dioxide, iron oxides, fire retardants such as alumina trihydrate, etc.
Selon un autre mode de réalisation préféré, le revêtement b. est un produit à base de peinture ou de résine à base époxy, polyuréthane, acrylique, vinylique ou siloxanique. According to another preferred embodiment, the coating b. is a product based on paint or resin based on epoxy, polyurethane, acrylic, vinyl or siloxane.
La couche de finition c. peut être une peinture à base de liant acrylique, vinylique, siloxanique, ou minéral (à base de chaux ou de silicate), mince ou structurée. Sa déclinaison sous différents aspects dans de nombreuses teintes permet un large choix pour assurer une meilleure compatibilité avec l'enduit existant par ailleurs sur la façade. Ainsi, l'élément de modénature sera totalement inclus dans l'esthétique générale de la façade, tout en assurant son rôle de barrière de protection anti-feu. The topcoat c. can be a paint based on acrylic binder, vinyl, siloxane, or mineral (based on lime or silicate), thin or structured. Its variation in various aspects in many shades allows a wide choice to ensure better compatibility with the existing coating on the facade. Thus, the element of modénature will be totally included in the general aesthetics of the facade, while ensuring its role of barrier of protection against fire.
LE PROCEDE DE FABRICATION DE L'ELEMENT DE MODENATURE THE METHOD OF MANUFACTURING THE MODENATURE ELEMENT
Le procédé de fabrication de l'élément de modénature selon l'invention fait intervenir une étape de découpe d'un matériau telle que de la laine de roche de masse volumique élevée sous forme d'une modénature, et en particulier d'un profilé. La découpe de la laine minérale est une technologie qui n'est pas utilisée jusqu'à présent dans le domaine du bâtiment. The method of manufacturing the molding element according to the invention involves a step of cutting a material such as rock wool of high density in the form of a mold, and in particular a profile. Cutting mineral wool is a technology that has not been used in the building industry until now.
La découpe à façon peut être réalisée par différentes techniques spécifiques, telles que sciage, estampage, tournage, fraisage, jet d'eau, découpe au laser. La variété des techniques à disposition permet une multiplicité des formes de profilés réalisables par le procédé de fabrication, ce qui est également un avantage non négligeable de l'invention.  Custom cutting can be carried out by various specific techniques, such as sawing, stamping, turning, milling, water jet, laser cutting. The variety of techniques available allows a multiplicity of shapes shapes achievable by the manufacturing process, which is also a significant advantage of the invention.
Il est également remarquable que l'élément de modénature puisse être enduit par le revêtement b. avant son transport et sa pose sur façade, afin de se présenter à l'utilisateur sous forme d'un élément de modénature prêt à poser. Il permet ainsi de s'affranchir d'une étape de découpe et d'enduction sur chantier ou en atelier, ce qui nécessite un outillage spécifique et une manipulation contraignante en plusieurs étapes pour l'installateur. L'étape d'application du revêtement peut être réalisée par toute méthode permettant d'obtenir l'épaisseur voulue pour chaque couche, notamment par application manuelle ou par projection. La couche de revêtement ainsi que l'éventuelle armature permettent également de protéger la modénature prête à poser d'éventuelles dégradations pouvant intervenir lors de son transport et de sa pose. LE SYSTEME D'ISOLATION THERMIQUE DES FAÇADES PAR L'EXTERIEUR It is also remarkable that the molding element can be coated with the coating b. before transporting and laying on the facade, in order to present itself to the user in the form of a ready-to-install modeling element. It thus makes it possible to avoid a step of cutting and coating on site or in the workshop, which requires specific tools and a binding manipulation in several stages for the installer. The coating application step may be performed by any method to obtain the desired thickness for each layer, including manual application or projection. The coating layer and the possible reinforcement can also protect the modeling ready to pose any damage that may occur during transport and installation. THE THERMAL INSULATION SYSTEM OF FACADES FROM THE OUTSIDE
Selon un mode de réalisation préféré de l'invention, les éléments du système d'isolation thermique des façades par l'extérieur se substituent en tout ou partie à des bandes filantes visant à limiter la propagation du feu en façade, en fonction de l'apport esthétique que l'on souhaite conférer au bâtiment. According to a preferred embodiment of the invention, the elements of the thermal insulation system of the facades from the outside are entirely or partially substituted for moving strips intended to limit the spread of fire in the facade, depending on the aesthetic contribution that one wishes to confer on the building.
LE PROCEDE DE REALISATION THE REALIZATION PROCESS
Les panneaux isolants posés sur la façade sont ceux classiquement utilisées dans les systèmes ETICS, notamment des panneaux de polystyrène expansé ou de polyuréthane expansé, ou de laine minérale. Ces panneaux sont collés ou fixés mécaniquement par des chevilles adaptées (système de fixation « calé-chevillé »). Les produits de collage ont de préférence à base de mortier colle minéral ciment ou mortier colle pâte. The insulating panels placed on the facade are those conventionally used in ETICS systems, in particular panels of expanded polystyrene or expanded polyurethane, or mineral wool. These panels are glued or mechanically fixed by suitable dowels ("wedge-pegged" fastening system). Bonding products are preferably based on mineral cement cement mortar or paste paste mortar.
Il est important que la découpe de l'élément de modénature soit aussi précise que possible pour assurer une pose parfaitement jointive entre les panneaux et l'élément de modénature, afin de remplir parfaite les conditions d'isolation thermique.  It is important that the cutting of the modeling element is as precise as possible to ensure a perfectly contiguous installation between the panels and the molding element, in order to perfectly fulfill the thermal insulation conditions.
La fixation des éléments de modénature sur la façade peut être réalisée par les moyens couramment utilisés pour fixer des panneaux isolants classiques dans des systèmes ETICS, notamment par des chevilles traversantes.  The fixing of the elements of modénature on the frontage can be carried out by the means commonly used to fix conventional insulating panels in systems ETICS, in particular by pegs through.
D'autres détails et caractéristiques avantageuses ressortiront ci-après de la description de modes de réalisation non limitatifs de l'invention en référence aux figures annexées dans lesquelles : Other details and advantageous characteristics will emerge below from the description of non-limiting embodiments of the invention with reference to the appended figures in which:
- la figure 1 représente de façon schématique des façades d'un bâtiment comportant un système d'isolation thermique par l'extérieur selon l'invention. La figure 2 représente de façon schématique une coupe en section transversale droite d'un élément de modénature selon l'invention. - Figure 1 schematically shows the facades of a building with an external thermal insulation system according to the invention. Figure 2 schematically shows a section in right cross section of a molding element according to the invention.
La figure 1, représente schématiquement et partiellement, un bâtiment dont au moins deux des façades ont été traitée en isolation thermique par l'extérieur. Les façades du bâtiment sont formées de murs en briques et couvertes de panneaux isolants (1) en polystyrène expansé, calés et chevillés sur le mur. En dessous de l'ouverture (2) existant sur la façade principale, une bande filante (3) en laine de roche, horizontale et continue, est fixée par collage en plein et par chevillage en lieu et place du polystyrène expansé. Au- dessus de l'ouverture (2) de la façade , à l'emplacement où devrait se trouver une bande filante selon les normes en vigueur, c'est-à-dire à une hauteur comprise entre 200 mm et 500 mm de l'ouverture, se trouve un élément de modénature (4) selon l'invention, constitué par un profilé dont le noyau est en laine minérale mono densité (Conductivité thermique 0,038 W/m.K, Masse volumique nominale 155 kg/m3), débordant de 300 mm de part et d'autre de l'ouverture. L'élément de modénature est collé et fixé mécaniquement au mur par des chevilles traversantes. Cet élément, du fait de sa nature incombustible (Euroclasse Al), joue également le rôle d'une barrière pour éviter la propagation du feu par la façade, dans le cas où un feu se déclenche à l'intérieur du bâtiment et est susceptible de se propager par l'extérieur. Figure 1 shows schematically and partially, a building of which at least two of the facades have been treated in thermal insulation from the outside. The facades of the building are made of brick walls and covered with insulating panels (1) expanded polystyrene, wedged and pegged on the wall. Below the opening (2) existing on the main facade, a strip strip (3) in rockwool, horizontal and continuous, is fixed by bonding in full and by pinning instead of expanded polystyrene. Above the opening (2) of the facade, where a strip should be in accordance with the standards in force, that is to say at a height of between 200 mm and 500 mm from the opening, is a molding element (4) according to the invention, consisting of a profile whose core is mono-density mineral wool (thermal conductivity 0.038 W / mK, nominal density 155 kg / m3), overflowing 300 mm on both sides of the opening. The modeling element is glued and mechanically fixed to the wall by pegs. This element, because of its incombustible nature (Euroclass Al), also acts as a barrier to prevent the spread of fire by the facade, in the event that a fire occurs inside the building and is likely to spread from the outside.
La figure 2 reprend en détail l'élément de modénature représenté sur la figure 1. Un noyau (5) en laine minérale (Conductivité thermique 0,038 W/m.K, Masse volumique nominale 155 kg/m ) est représenté, recouvert d'une couche (6) d'enduit acrylique en pâte prête à l'emploi à base de copolymères acryliques et de charges minérales (Produit Armenduit FX commercialisé par Zolpan), puis d'une couche (7) de peinture. FIG. 2 shows in detail the modeling element represented in FIG. 1. A core (5) of mineral wool (thermal conductivity 0.038 W / mK, nominal density 155 kg / m) is represented, covered with a layer ( 6) acrylic paste paste ready to use based on acrylic copolymers and mineral fillers (Armenduit FX product marketed by Zolpan), then a layer (7) of paint.
