Description
DESCRIZIONE dell'invenzione avente per titolo: DESCRIPTION of the invention having as title:
"Pannello multistrato per il rivestimento di superfici esterne di un edificio" "Multilayer panel for covering the external surfaces of a building"
CAMPO DELL'INVENZIONE FIELD OF THE INVENTION
Il presente trovato riguarda un pannello multistrato accoppiabile alle superfici esterne di un edificio, quali la facciata, il tetto, un lastrico solare, ecc., che ha almeno proprietà isolanti termicamente ed acusticamente, non disgiunte da caratteristiche di resistenza strutturale che ne aumentano la vita utile una volta installato. The present invention relates to a multilayer panel that can be coupled to the external surfaces of a building, such as the facade, the roof, a flat roof, etc., which has at least thermally and acoustically insulating properties, not separated from structural resistance characteristics which increase its life. useful once installed.
STATO DELLA TECNICA STATE OF THE TECHNIQUE
Nel campo delle costruzioni è tecnica nota dotare le pareti o i tetti di alcuni edifici di pannelli multistrato che mostrano diverse proprietà, tra cui quella più rilevante è quella di isolamento termico ed acustico. In the construction field it is known technique to equip the walls or roofs of some buildings with multilayer panels which show different properties, among which the most important is that of thermal and acoustic insulation.
Tali pannelli multistrato possono comprendere strati di materiali differenti che sono tra loro fissati mediante film adesivi a comporre un "sandwich", le cui proprietà chimiche e fisiche sono determinate dall'accoppiamento di tali strati. Such multilayer panels can comprise layers of different materials which are fixed to each other by means of adhesive films to form a "sandwich", the chemical and physical properties of which are determined by the coupling of these layers.
Ad esempio, sono noti pannelli per superfici di un edificio comprendenti lastre in materiale polimerico tra loro accoppiate con l'interposizione di un materiale coibente, quale la lana di vetro o di roccia. Un rivestimento decorativo o protettivo esterno può essere disposto sopra la lastra polimerica più esterna. For example, panels for surfaces of a building are known comprising plates of polymeric material coupled together with the interposition of an insulating material, such as glass or rock wool. An external decorative or protective coating can be placed on top of the outermost polymer sheet.
In alcuni di tali pannelli multistrato è prevista l'interposizione di uno strato in fibra di vetro tra due strati in un materiale polimerico, con lo scopo di rendere strutturalmente più resistenti tali strati polimerici e quindi il pannello stesso. In some of these multilayer panels, the interposition of a layer of glass fiber is provided between two layers of a polymeric material, with the aim of making these polymeric layers and therefore the panel itself structurally more resistant.
Nella domanda di brevetto internazionale WO 2016/120749 Al sono descritti pannelli multistrato in cui uno strato interno ed uno strato esterno basati su matrici polimeriche o organiche con cariche minerali sono tra loro accoppiati mediante l'interposizione di uno strato in fibra di vetro. In the international patent application WO 2016/120749 A1, multilayer panels are described in which an inner layer and an outer layer based on polymeric or organic matrices with mineral fillers are coupled together by interposing a layer of glass fiber.
Nella privativa cinese CN201517256 U si descrivono pannelli multistrato per la coibentazione di superfici di edifici, al cui interno è previsto uno strato di fibra di vetro accoppiato, sulle proprie superfici opposte, a degli strati anti-urto decorativi di tipo polimerico. The Chinese patent CN201517256 U describes multilayer panels for the insulation of building surfaces, inside which there is a layer of glass fiber coupled, on its opposite surfaces, with decorative anti-impact polymeric layers.
In altre forme di realizzazione, quale quella descritta in KR 20180003484 A, uno strato in fibra di vetro è interposto in un pannello multistrato che presenta, quale strato più esterno, una cella fotovoltaica. In other embodiments, such as that described in KR 20180003484 A, a glass fiber layer is interposed in a multilayer panel which has a photovoltaic cell as its outermost layer.
Appare quindi chiaro che l'impiego di uno strato in fibra di vetro in pannelli multistrato per il rivestimento di superfici di edifici sia confinato nell'arte nota all'accoppiamento di tale strati di fibra di vetro a strati, o lastre, in materiale polimerico, allo scopo di incrementare la resistenza meccanica (strutturale) di tali strati polimerici. It therefore appears clear that the use of a layer of glass fiber in multilayer panels for covering building surfaces is confined in the known art to the coupling of such layers of glass fiber to layers, or plates, in polymeric material, in order to increase the mechanical (structural) strength of these polymeric layers.
Sono infine noti pannelli multistrato comprendenti due lastre di vetro tra loro affacciate con l'interposizione di una lastra, o film, in materiale polimerico trasparente con proprietà isolanti, che tuttavia non sono destinati al rivestimento di superfici esterne di un edificio, quali facciate, tetti, lastrici, ecc., dato che essi sono esclusivamente destinati a costituire finestre o pareti trasparenti di un edificio. Tali pannelli non sono solitamente applicabili a tali superfici esterne di un edificio. RIASSUNTO DELL'INVENZIONE Finally, multilayer panels are known comprising two glass sheets facing each other with the interposition of a sheet, or film, in transparent polymeric material with insulating properties, which however are not intended for covering external surfaces of a building, such as facades, roofs. , flagstones, etc., since they are exclusively intended to form transparent windows or walls of a building. Such panels are not usually applicable to such exterior surfaces of a building. SUMMARY OF THE INVENTION
È uno scopo del presente trovato quello di fornire un pannello multistrato accoppiabile a superfici di edifici che presenti proprietà di isolamento termico ed acustico paragonabili o migliori a quelli dello stato della tecnica e che nel contempo presenti una migliore resistenza strutturale e meccanica. It is an object of the present invention to provide a multilayer panel which can be coupled to building surfaces which has thermal and acoustic insulation properties comparable or better to those of the state of the art and which at the same time has better structural and mechanical strength.
Un ulteriore scopo del presente trovato è quello di provvedere un pannello multistrato per il rivestimento di superfici di un edificio che presenti anche proprietà di impervietà al fuoco, oltre che decorative. A further object of the present invention is to provide a multilayer panel for covering surfaces of a building which also has fireproof properties, as well as decorative.
Ancora uno scopo del presente trovato è quello di realizzare un pannello multistrato per il rivestimento di superfici di un edificio che possa svolgere anche funzioni di recupero dell'energia assorbita. Another object of the present invention is to provide a multilayer panel for covering the surfaces of a building which can also perform functions of recovering the absorbed energy.
Questi ed altri scopi sono raggiunti dal pannello multistrato accoppiabile a superfici di un edificio che comprende un primo strato interno affacciato in uso alla superficie esterna di un edificio, almeno un secondo strato esterno rivolto verso l'ambiente circostante, ed uno strato intermedio posto tra detti primo e secondo strato, e in cui dei relativi film di adesivo fissano tra loro tali strati. Vantaggiosamente, il primo strato interno di questo pannello multistrato è realizzato in vetro e il relativo strato intermedio è uno strato in vetroresina. These and other purposes are achieved by the multilayer panel which can be coupled to surfaces of a building which comprises a first internal layer facing the external surface of a building in use, at least a second external layer facing the surrounding environment, and an intermediate layer placed between said first and second layer, and in which relative adhesive films fix these layers together. Advantageously, the first internal layer of this multilayer panel is made of glass and the relative intermediate layer is a fiberglass layer.
Si osservi che qui e nel seguito con il termine "strato" si intende un elemento a forma di lastra, o comunque prismatico con due dimensioni, lunghezza e larghezza, maggiori della terza, spessore. Inoltre, gli strati che costituiscono il pannello oggetto di rivendicazione differiscono tra loro per il solo spessore, ovvero gli strati accoppiati che definiscono tale pannello hanno tutti le medesime due dimensioni maggiori, differendo al più tra loro per la dimensione minore. It should be noted that here and in the following the term "layer" refers to an element in the form of a plate, or in any case prismatic with two dimensions, length and width, greater than the third, thickness. Furthermore, the layers that constitute the panel according to the claim differ from each other only in thickness, ie the coupled layers that define this panel all have the same two larger dimensions, differing at most from each other by the smaller dimension.
In pratica, gli strati che costituiscono il pannello rivendicato hanno identica lunghezza e larghezza e possono invece avere differente spessore. In practice, the layers that make up the claimed panel have identical length and width and can instead have different thickness.
Secondo un aspetto preferito del presente trovato, questo pannello multistrato prevede che lo strato intermedio in vetroresina, preferibilmente realizzato tramite una matrice poliestere con fibre di vetro, abbia spessore compreso tra 1mm e 3 mm, abbia altresì durezza Barcoal compresa tra 35 e 50 (UNI EN 59) e resistenza a trazione (UNI EN ISO 572) compresa tra 100 MPa e 300Mpa. According to a preferred aspect of the present invention, this multilayer panel provides that the intermediate fiberglass layer, preferably made by means of a polyester matrix with glass fibers, has a thickness between 1mm and 3 mm, and also has a Barcoal hardness between 35 and 50 (UNI EN 59) and tensile strength (UNI EN ISO 572) between 100 MPa and 300Mpa.
Si noti che nessuno dei pannelli multistrato noti alla tecnica prevede di accoppiare uno strato in fibra di vetro, in particolare con le caratteristiche fisiche anzidette, ad uno strato interno in vetro, al fine di aumentare l'isolamento termico ed acustico e anche l'impervietà al fuoco di un simile pannello. It should be noted that none of the multilayer panels known in the art provides for coupling a layer of glass fiber, in particular with the aforementioned physical characteristics, to an internal glass layer, in order to increase the thermal and acoustic insulation and also the imperviousness. to the fire of such a panel.
Secondo una forma di realizzazione preferita, il suddetto secondo strato esterno di tale pannello multistrato è in materiale vetroso o è un substrato di una o più celle fotovoltaiche. According to a preferred embodiment, the aforementioned second outer layer of this multilayer panel is made of glassy material or is a substrate of one or more photovoltaic cells.
In questo modo, è possibile aumentare la coibentazione termica offerta dal pannello oggetto di questa privativa e/o è possibile attuare forme di recupero energetico, convertendo l'energia solare in energia elettrica tramite le celle fotovoltaiche. In this way, it is possible to increase the thermal insulation offered by the panel subject to this patent and / or it is possible to implement forms of energy recovery, converting solar energy into electricity through photovoltaic cells.
Si noti che è possibile associare tra loro pannelli multistrato dotati, secondo il presente trovato, di uno strato esterno in vetro e di uno strato esterno costituito dal substrato di una o più celle fotovoltaiche su una medesima superficie, ad esempio una facciata o un tetto, di un edifico, ottenendo comunque un gradevole effetto decorativo. It should be noted that it is possible to associate with each other multilayer panels equipped, according to the present invention, with an outer layer of glass and an outer layer consisting of the substrate of one or more photovoltaic cells on the same surface, for example a facade or a roof, of a building, still obtaining a pleasant decorative effect.
In una ulteriore forma preferita di realizzazioni i suddetti film di adesivo sono scelti tra film in PVB ( PoliVinilButirrale) e/o film in EVA (Etilene Vinil Acetato). In a further preferred embodiment, the above adhesive films are selected from PVB (PolyVinyl Butyral) and / or EVA (Ethylene Vinyl Acetate) films.
Secondo un altro aspetto del presente trovato, il pannello comprende un telaio laterale esterno realizzato almeno parzialmente in alluminio. According to another aspect of the present invention, the panel comprises an external side frame made at least partially of aluminum.

Il pannello multistrato 1 qui descritto ha quindi lo scopo di rivestire una superficie esterna 7 di un edificio, quale ad esempio una facciata, il tetto, un lastrico solare, una pavimentazione esterna, ecc. The multilayer panel 1 described here therefore has the purpose of covering an external surface 7 of a building, such as for example a facade, the roof, a flat roof, an external flooring, etc.
Si noti che, secondo quanto qui inteso e con riferimento anche alla figura 2, lo strato interno 2 del pannello multistrato 1 può così essere direttamente montato su una superficie esterna 7 di un edificio, quale la facciata, il tetto, un lastrico solare, un pavimento esterno ecc., secondo modalità note nel settore, oppure può essere fissato a tale superficie esterna 7 mediante l'interposizione di altri strati appartenenti o meno al pannello 1 e qui non menzionati. It should be noted that, according to what is intended here and with reference also to Figure 2, the internal layer 2 of the multilayer panel 1 can thus be directly mounted on an external surface 7 of a building, such as the facade, the roof, a flat roof, a external floor etc., according to methods known in the sector, or it can be fixed to said external surface 7 by interposing other layers belonging or not to panel 1 and not mentioned here.
Il pannello multistrato 1, in una sua preferita forma di realizzazione qui illustrata, comprende una lastra in vetro quale strato interno 2 e comprende altresì, quale strato intermedio 3, una lastra, o materassino, in vetroresina, tra loro stabilmente associati. The multilayer panel 1, in one of its preferred embodiments illustrated here, comprises a glass plate as an internal layer 2 and also comprises, as an intermediate layer 3, a fiberglass plate or mat, stably associated with each other.
Vantaggiosamente, secondo il presente trovato, tale primo strato interno 2 in vetro e tale strato intermedio 4 in vetroresina sono tra loro direttamente accoppiati tramite l'interposizione (si veda anche la figura 3) di un primo film adesivo 5, costituito ad esempio da ÈVA (Etilene Vinil Acetato) o da PVB (PoliVinilButirrale). Gli strati interno 2, esterno 3, ed intermedio 4 hanno tutti la medesima larghezza e lunghezza e presentano al più tra di loro un differente spessore. Advantageously, according to the present invention, this first internal layer 2 in glass and this intermediate layer 4 in fiberglass are directly coupled to each other through the interposition (see also Figure 3) of a first adhesive film 5, consisting for example of EVA (Ethylene Vinyl Acetate) or from PVB (PolyVinyl Butyral). The inner 2, outer 3, and intermediate 4 layers all have the same width and length and have at most a different thickness between them.
L'abbinamento di uno strato interno in vetro 2 ad uno strato intermedio in vetroresina 4 consente di ottenere un pannello multistrato 1 dotato di un insieme di proprietà ignifughe, ovverosia di impervietà alla fiamma, e di caratteristiche strutturali, ossia di resistenza meccanica, che non sono identicamente presenti nei pannelli di rivestimento noti. The combination of an internal layer of glass 2 with an intermediate layer of fiberglass 4 allows to obtain a multilayer panel 1 with a set of fireproof properties, that is, imperviousness to flame, and structural characteristics, i.e. mechanical resistance, which do not they are identically present in known cladding panels.
Lo strato intermedio in vetroresina 4 è poi accoppiato, sulla sua superficie non vincolata allo strato interno in vetro 2, ad uno strato esterno 3, costituito da una o più lastre di materiale isolante e/o protettivo e/o decorativo, tramite un secondo film adesivo 6, anch'esso ad esempio in EVA o in PVB. The intermediate fiberglass layer 4 is then coupled, on its surface not bound to the inner glass layer 2, to an outer layer 3, consisting of one or more plates of insulating and / or protective and / or decorative material, by means of a second film adhesive 6, also for example in EVA or PVB.
Nella realizzazione qui mostrata, lo strato esterno 3 del pannello multistrato 1 è di preferenza uno strato esposto a, ovvero a diretto contatto con, l'ambiente circostante e in particolare può essere costituito da una lastra in vetro, con funzioni coibenti, protettive dagli agenti esterni e/o decorative, o da un substrato di una o più celle fotovoltaiche e/o da almeno un pannello solare, con funzione di recupero dell'energia solare incidente sulla superficie dell'edificio a cui il pannello 1 è vincolato. In the embodiment shown here, the outer layer 3 of the multilayer panel 1 is preferably a layer exposed to, or in direct contact with, the surrounding environment and in particular it can consist of a glass plate, with insulating functions, protecting against agents external and / or decorative, or from a substrate of one or more photovoltaic cells and / or from at least one solar panel, with the function of recovering the solar energy incident on the surface of the building to which the panel 1 is bound.
Si noti che è possibile prevedere, sulla medesima superficie esterna 7 di un edificio, l'impiego abbinato di pannelli 1 dotati di uno strato esterno 3 in vetro con pannelli 1 dotati di uno strato esterno 3 costituito dal substrato di una o più celle fotovoltaiche e/o da almeno un pannello solare, costituito ad esempio da un pannello fotovoltaico e/o da un pannello solare di tipo termico. In questo modo, si può ottenere una gradevole decorazione di una superficie esterna di un edificio, non disgiunta dalla possibilità di recupero dell'energia termica incidente sui pannelli 1 che ricoprono in questo modo la superficie esterna 7 di un edificio. It should be noted that it is possible to provide, on the same external surface 7 of a building, the combined use of panels 1 equipped with an external layer 3 in glass with panels 1 equipped with an external layer 3 consisting of the substrate of one or more photovoltaic cells and / or by at least one solar panel, consisting for example of a photovoltaic panel and / or a thermal solar panel. In this way, it is possible to obtain a pleasant decoration of an external surface of a building, not separated from the possibility of recovering the thermal energy incident on the panels 1 which thus cover the external surface 7 of a building.
Lo strato intermedio 4 del pannello 1 può svolgere funzione di incremento della resistenza strutturale anche per tale strato esterno 3 dello stesso pannello multistrato 1. The intermediate layer 4 of the panel 1 can perform the function of increasing the structural strength also for this external layer 3 of the same multilayer panel 1.
Come si vedrà, tale strato intermedio 4 in vetroresina può anche svolgere una addizionale funzione decorativa allorquando tale strato intermedio 4 viene abbinato ad uno strato esterno in un materiale almeno in parte trasparente, ad esempio vetro, ed è colorato o decorato con motivi visibili dall'esterno del pannello 1. As will be seen, this fiberglass intermediate layer 4 can also perform an additional decorative function when this intermediate layer 4 is combined with an outer layer made of an at least partly transparent material, for example glass, and is colored or decorated with patterns visible from the outside panel 1.
Si osservi che lo strato esterno 3 del pannello 1 qui descritto può essere alternativamente costituito da una qualsiasi lastra di materiale noto con proprietà protettive e/o coibenti e/o decorative, ad esempio anche materiali naturali (quali lastre lapidee) oppure può essere costituito, in forme di realizzazione qui non mostrate, da una pluralità di elementi lastriformi strutturali o funzionali e film (pellicole) adesivi a costituire un "sandwich". It should be noted that the outer layer 3 of the panel 1 described here can alternatively be constituted by any plate of known material with protective and / or insulating and / or decorative properties, for example also natural materials (such as stone plates) or it can be constituted, in embodiments not shown here, from a plurality of structural or functional sheet-like elements and adhesive films (films) to form a "sandwich".
Lo strato esterno 3 può anche comprendere elementi funzionali per il recupero dell'energia solare assorbita dal pannello 1 differenti dalle sopra menzionate celle fotovoltaiche, quali ad esempio dei condotti per un fluido di una cella solare termica, senza con ciò uscire dall'ambito di tutela qui richiesto. The outer layer 3 can also comprise functional elements for the recovery of the solar energy absorbed by the panel 1 different from the aforementioned photovoltaic cells, such as, for example, ducts for a fluid of a thermal solar cell, without thereby departing from the scope of protection. required here.
Si noti in ogni caso che tale strato esterno 3, in forme di realizzazione alternative del presente trovato qui non illustrate, non necessariamente è disposto a diretto contatto con l'ambiente circostante e può quindi essere costituito da lastre o elementi lastriformi di materiali con diverse proprietà, quali ad esempio materiali polimerici atti alla coibentazione termica o acustica. It should be noted in any case that this outer layer 3, in alternative embodiments of the present invention not illustrated here, is not necessarily disposed in direct contact with the surrounding environment and can therefore be made up of sheets or sheet-like elements of materials with different properties , such as for example polymeric materials suitable for thermal or acoustic insulation.
Tale strato esterno 3, sia che risulti esposto all'ambiente esterno, sia che esso sia ricoperto da ulteriori strati, è infatti solitamente preposto a garantire un efficace isolamento termico ed acustico, così che il pannello multistrato 1 qui illustrato possa possedere sia caratteristiche di impervietà al fuoco, date dallo strato interno 2 in vetro, sia caratteristiche di isolamento termico ed acustico, fornite dallo strato interno 2, dallo strato intermedio in vetroresina 4, e soprattutto dallo strato esterno 3, sia adeguate caratteristiche di resistenza meccanica e strutturale, date anche dallo strato intermedio in vetroresina 4. This external layer 3, whether it is exposed to the external environment, or whether it is covered by further layers, is in fact usually designed to ensure effective thermal and acoustic insulation, so that the multilayer panel 1 illustrated here can have both impervious characteristics to fire, given by the internal glass layer 2, both thermal and acoustic insulation characteristics, provided by the internal layer 2, by the intermediate fiberglass layer 4, and above all by the external layer 3, and adequate mechanical and structural resistance characteristics, also given from the intermediate fiberglass layer 4.
Secondo un aspetto di questo trovato, il pannello multistrato 1, con riferimento alla figura 3, può comprendere esclusivamente uno strato interno 2 in vetro, uno strato intermedio 4 in vetroresina accoppiato allo strato interno 2 tramite un film adesivo 5 in EVA o PVB, ed uno strato esterno 3, accoppiato allo strato intermedio 4 tramite un altro film adesivo 6 in EVA o PVB. Tale pannello multistrato 1 è quindi incorniciato da un telaio metallico, qui non mostrato, preferibilmente realizzato in alluminio. Tale telaio metallico circonda i bordi delle lastre che costituiscono il pannello 1 multistrato, fornendo ulteriori proprietà di resistenza strutturale allo stesso pannello 1. According to one aspect of this invention, the multilayer panel 1, with reference to Figure 3, can only comprise an internal layer 2 of glass, an intermediate layer 4 of fiberglass coupled to the internal layer 2 by means of an adhesive film 5 of EVA or PVB, and an external layer 3, coupled to the intermediate layer 4 by means of another adhesive film 6 in EVA or PVB. Said multilayer panel 1 is therefore framed by a metal frame, not shown here, preferably made of aluminum. This metal frame surrounds the edges of the slabs that make up the multilayer panel 1, providing further structural strength properties to the panel 1 itself.
In una forma esemplificativa di quest'ultimo pannello multistrato 1, lo strato interno in vetro 2 può avere spessore compreso tra 3mm e 10mm, lo strato intermedio in vetroresina 4 può avere spessore compreso tra Imm e 3mm, e lo strato esterno in vetro 3 può avere spessore compreso tra 3mm e 30mm. La superficie frontale del pannello 1 può essere ad esempio compresa tra 0,5 m<2 >e 4 m<2>. Superfici frontali di minore o maggiore estensione non sono comunque escluse. Nella forma di realizzazione del pannello multistrato 1 qui illustrata, lo strato intermedio 4 in vetroresina preferibilmente comprende una matrice in poliestere e fibre di vetro. Tale matrice in poliestere può essere stabilizzata tramite irradiazione con raggi ultravioletti (UV). In an exemplary form of the latter multilayer panel 1, the inner glass layer 2 can have a thickness between 3mm and 10mm, the intermediate fiberglass layer 4 can have a thickness between Imm and 3mm, and the outer glass layer 3 can have a thickness between 3mm and 30mm. The front surface of the panel 1 can for example be between 0.5 m <2> and 4 m <2>. However, smaller or larger frontal surfaces are not excluded. In the embodiment of the multilayer panel 1 illustrated here, the intermediate layer 4 in fiberglass preferably comprises a matrix of polyester and glass fibers. This polyester matrix can be stabilized by irradiation with ultraviolet (UV) rays.
Facoltativamente, lo strato intermedio in vetroresina 4 può altresì comprendere uno strato protettivo di gealcoat (resina poliestere isoftalica). Optionally, the intermediate fiberglass layer 4 can also comprise a protective layer of gealcoat (isophthalic polyester resin).
Si osservi che in forme di realizzazione alternative del presente trovato, tale strato intermedio 4 in vetroresina può comprendere genericamente una matrice in una resina termoindurente rinforzata da fibre di vetro. It should be noted that in alternative embodiments of the present invention, this intermediate layer 4 in fiberglass can generally comprise a matrix in a thermosetting resin reinforced with glass fibers.
Di preferenza, al fine di ottenere le richieste caratteristiche di resistenza meccanica del pannello multistrato 1, lo strato intermedio 4 in vetroresina può avere durezza Barcoal compresa tra 35 e 50 (UNI EN 59) e resistenza a trazione (UNI EN ISO 572) compresa tra 100 MPa e 300Mpa. Lo spessore di questo strato intermedio in vetroresina 4, come detto, può essere compreso tra Imm e 3mm. Ulteriormente, in una forma di realizzazione preferita del presente trovato, tale strato intermedio 4 può essere abbinato ad uno strato esterno 3 in un materiale almeno in parte trasparente (ad esempio vetro non colorato), e può in questo caso svolgere funzione decorativa. Infatti, lo strato intermedio 4 in vetroresina può comprendere una matrice polimerica che, a scopi decorativi, può essere variamente colorata o avere una particolare finitura superficiale almeno sul lato destinato all'accoppiamento allo strato esterno 3, così da creare particolari effetti estetici visibili dall'esterno del pannello 1, quando quest'ultimo è montato sulla relativa superficie esterna 7 di un edificio. Preferably, in order to obtain the required characteristics of mechanical resistance of the multilayer panel 1, the intermediate layer 4 in fiberglass can have Barcoal hardness between 35 and 50 (UNI EN 59) and tensile strength (UNI EN ISO 572) between 100 MPa and 300Mpa. The thickness of this fiberglass intermediate layer 4, as mentioned, can be between Imm and 3mm. Furthermore, in a preferred embodiment of the present invention, this intermediate layer 4 can be combined with an outer layer 3 made of an at least partly transparent material (for example, non-colored glass), and can in this case perform a decorative function. In fact, the intermediate layer 4 in fiberglass can comprise a polymeric matrix which, for decorative purposes, can be variously colored or have a particular surface finish at least on the side intended for coupling to the external layer 3, so as to create particular aesthetic effects visible from the panel 1, when the latter is mounted on the relative external surface 7 of a building.
L'applicazione del pannello multistrato 1 ad una superficie esterna 7 di un edificio può essere effettuata tramite noti sistemi meccanici, ad esempio mediante l'imbullonatura del telaio laterale esterno, preferibilmente in alluminio, del pannello 1 stesso ad una componente strutturale fissata alla superficie esterna dell'edificio tramite ancoraggio meccanico, stuccatura, adesivi, ecc., in funzione delle dimensioni dello stesso pannello multistrato 1 e della superficie esterna 7 dell'edificio da rivestire. The application of the multilayer panel 1 to an external surface 7 of a building can be carried out by means of known mechanical systems, for example by bolting the external lateral frame, preferably in aluminum, of the panel 1 itself to a structural component fixed to the external surface. of the building by mechanical anchoring, grouting, adhesives, etc., depending on the size of the multilayer panel 1 and the external surface 7 of the building to be covered.
