VITRAGE MULTIPLE A PROPRIETESMULTIPLE GLAZING WITH PROPERTIES
D'ISOLATION ACOUSTIQUE ET THERMIQUE io La présente invention concerne un vitrage multiple de protection acoustique monté dans une fenêtre comprenant un premier panneau de verre feuilleté et au moins un second panneau de verre simple, parallèle au premier panneau et séparé de celuici par une lame de gaz, les feuilles de verre du panneau feuilleté étant réunies par au moins un film plastique. De tels vitrages sont en général destinés à équiper des bâtiments de manière à diminuer à l'intérieur, la perception des bruits extérieurs, et à assurer une protection thermique. The present invention relates to a multiple acoustic protection glazing mounted in a window comprising a first laminated glass panel and at least a second single glass panel, parallel to the first panel and separated therefrom by a glass plate. gas, the glass sheets of the laminated panel being joined by at least one plastic film. Such glazings are generally intended to equip buildings so as to decrease inside, the perception of external noise, and to provide thermal protection.
Depuis plusieurs années, dans de nombreux pays, l'utilisation de vitrages isolants thermiques s'est généralisée. Le plus souvent, ils sont constitués de deux verres de même épaisseur, généralement comprise entre 2,5 et 4 mm, séparés par une lame de gaz de 6 à 16 mm et collés à leur périphérie à l'aide de mastics variés et éventuellement de profilés métalliques. Pendant la période de chauffage, de tels vitrages améliorent le confort des locaux d'habitation, de travail et de loisir et diminuent sensiblement les déperditions thermiques. Sur le plan de l'isolement acoustique, un vitrage comprenant un verre de 4 mm, une lame de gaz de 12 mm et un verre de 10 mm constitue une référence appropriée. For many years, in many countries, the use of thermal insulating glass has become widespread. Most often, they consist of two glasses of the same thickness, generally between 2.5 and 4 mm, separated by a gas strip of 6 to 16 mm and glued to their periphery with various mastics and possibly metal profiles. During the heating period, such glazings improve the comfort of living quarters, work and leisure and significantly reduce heat loss. In terms of sound insulation, a glazing unit comprising a 4 mm glass, a 12 mm gas blade and a 10 mm glass is an appropriate reference.
En vue de répondre à certaines exigences d'isolation thermique ou d'insonorisation, il a déjà été proposé d'autres types de vitrages, que sont les vitrages multiples et feuilletés. Cependant, ces derniers posent des problèmes de poids et de volume par rapport aux fenêtres dans lesquels ils sont intégrés. En particulier, de tels vitrages sont réalisés avec des panneaux de verre simple qui présentent généralement des épaisseurs supérieures à 8 mm, et des panneaux de verre feuilleté usuellement employés qui sont généralement constitués de feuilles de verre d'épaisseur minimum de 4 mm. Aussi on obtient des vitrages multiples très encombrants et présentant un poids supérieur à la moyenne, et en particulier supérieur au poids d'un vitrage isolant de référence, tel que cité plus haut. In order to meet certain requirements of thermal insulation or soundproofing, it has already been proposed other types of glazing, that is the multiple glazing and laminated. However, these pose problems of weight and volume compared to the windows in which they are integrated. In particular, such glazings are made with simple glass panels which generally have thicknesses greater than 8 mm, and laminated glass panels usually used which are generally made of glass sheets with a minimum thickness of 4 mm. Thus we obtain very bulky multiple glazings and having a weight greater than the average, and in particular greater than the weight of a reference insulating glazing, as mentioned above.
L'invention a donc pour but de fournir un vitrage pour assurer une protection thermique et acoustique aussi performante qu'un vitrage isolant de référence ou qu'un vitrage multiple et feuilleté, sans présenter un poids aussi élevé. The invention therefore aims to provide a glazing to provide thermal and acoustic protection as effective as a reference insulating glazing or multiple glazing and laminated, without having such a high weight.
Le vitrage multiple selon l'invention, est caractérisé en ce que les deux feuilles de verre du panneau de verre feuilleté présentent chacune une épaisseur comprise entre 1,5 et 2,5 mm, et le panneau de verre simple présente une io épaisseur comprise entre 3 et 5 mm, et que le poids du vitrage est inférieur à au moins 30 % du poids d'un vitrage isolant qui comprend au moins deux feuilles de verre simple séparées par une lame de gaz présentant la même épaisseur que celle du vitrage multiple, l'écart entre l'indice d'affaiblissement acoustique pondéré RW du vitrage multiple et l'indice d'affaiblissement acoustique pondéré RA, dudit vitrage isolant avec deux feuilles de verre simple, n'excédant pas plus de 3 dB. The multiple glazing according to the invention is characterized in that the two glass sheets of the laminated glass panel each have a thickness of between 1.5 and 2.5 mm, and the single glass panel has a thickness between 3 and 5 mm, and that the weight of the glazing is less than at least 30% of the weight of an insulating glazing unit which comprises at least two sheets of single glass separated by a gas strip having the same thickness as that of the multiple glazing, the difference between the RW-weighted sound reduction index of the multiple glazing unit and the RA-weighted sound reduction index of the said insulating glazing unit with two single-glass sheets, not exceeding more than 3 dB.
On notera que dans toute la description, les valeurs numériques données pour les épaisseurs de verre sont considérées avec une incertitude à 5% près. It should be noted that throughout the description, the numerical values given for the glass thicknesses are considered with an uncertainty of 5%.
De préférence, le poids du vitrage multiple est inférieur d'au moins 40% du poids du vitrage isolant avec deux feuilles de verre simple. Preferably, the weight of the multiple glazing is at least 40% less than the weight of the insulating glass with two sheets of single glass.
Avantageusement, l'écart entre l'indice d'affaiblissement acoustique pondéré Rw du vitrage multiple et l'indice d'affaiblissement acoustique pondéré RW dudit vitrage isolant avec deux feuilles de verre simple, n'excède pas plus de 2 dB, les indices pouvant même être équivalents. Advantageously, the difference between the weighted sound reduction index Rw of the multiple glazing unit and the weighted sound reduction index RW of said insulating glazing unit with two sheets of single glass, does not exceed more than 2 dB, the indices being able to even be equivalent.
Selon une caractéristique, les lames de gaz ont une épaisseur comprise 25 entre 6 et 20 mm, et de préférence de 12 mm. According to one characteristic, the gas strips have a thickness of between 6 and 20 mm, and preferably 12 mm.
Selon une autre caractéristique, le film plastique du panneau de verre feuilleté a une épaisseur égale ou supérieure à 0,38 mm. According to another characteristic, the plastic film of the laminated glass panel has a thickness equal to or greater than 0.38 mm.
Avantageusement, ce film plastique est un film donnant des propriétés d'isolement acoustique améliorées. Advantageously, this plastic film is a film giving improved acoustic insulation properties.
On nomme film à propriétés d'isolement acoustique améliorées, un film remplissant les critères tels que définis dans les brevets EP-B1-0 100 701 ou EPB1-0 844 075, en particulier pour apporter une bonne protection acoustique contre les bruits routiers ou solidiens. The film with improved acoustic insulation properties is called a film fulfilling the criteria as defined in patents EP-B1-0 100 701 or EPB1-0 844 075, in particular for providing good acoustic protection against road or solidary noise. .
Dans le brevet EP-B1-0 100 701, le film est choisi tel qu'un barreau de 9 cm de longueur et de 3 cm de largeur, constitué d'un verre feuilleté comprenant deux feuilles de verre de 4 mm, d'épaisseur réunies par une couche de 2 mm de ce film, ait une fréquence critique qui diffère au plus de 35 % de celle d'un barreau de verre ayant la même longueur, la même largeur et 4 mm d'épaisseur. In patent EP-B1-0 100 701, the film is chosen such as a bar 9 cm long and 3 cm wide, consisting of a laminated glass comprising two glass sheets 4 mm thick. 2 mm layer of this film has a critical frequency which differs by at most 35% from that of a glass rod having the same length, the same width and 4 mm thickness.
Dans le brevet EP-B1-0 844 075, le film intercalaire est retenu lorsqu'il possède un facteur de perte tans supérieur à 0,6 et un module de cisaillement G' inférieure à 2.10' N/cm2, dans un domaine de température compris entre 10 et 60 C, dans un domaine de fréquence compris entre 50 et 10 000 Hz. In patent EP-B1-0 844 075, the interlayer film is retained when it possesses a loss factor greater than 0.6 and a shear modulus G 'of less than 2.10 N / cm 2, in a temperature range. between 10 and 60 C in a frequency range between 50 and 10,000 Hz.
io Ou bien, on préférera appliquer pour choisir un film à propriétés d'isolement acoustique améliorées les critères de sélection du brevet EPB1-0 387 148, lorsqu'il s'agira plutôt d'assurer une protection par rapport aux bruits aérodynamiques. Ce brevet européen propose d'utiliser un vitrage feuilleté dont l'intercalaire a un amortissement à la flexion v = Af& supérieur à 0,15, la mesure étant effectuée en excitant par un choc un barreau de 9 cm de longueur et 3 cm de largeur fait d'un verre feuilleté où la résine est entre deux verres épais chacun de 4 mm, et en mesurant la fréquence de résonance du premier mode fc et la largeur du pic M à une amplitude A/V2 où A est l'amplitude maximum à la fréquence fc de telle sorte que son indice d'affaiblissement acoustique ne se différencie pour aucune des fréquences supérieures à 800 hertz de plus de 5 décibels d'un indice de référence augmentant de 9 dB par octave jusqu'à 2000 Hz et de 3 dB par octave aux fréquences supérieures. Or, it will be preferable to apply to select a film with improved acoustic insulation properties the selection criteria of patent EPB1-0 387 148, when it will rather provide protection against aerodynamic noise. This European patent proposes to use a laminated glazing whose interlayer has a bending damping v = Af & greater than 0.15, the measurement being performed by exciting by shock a bar of 9 cm in length and 3 cm in width. made of a laminated glass where the resin is between two thick glasses each of 4 mm, and by measuring the resonance frequency of the first mode fc and the width of the peak M at an amplitude A / V2 where A is the maximum amplitude at the frequency fc so that its sound attenuation index does not differ for any of the frequencies above 800 Hz by more than 5 decibels by a reference index increasing by 9 dB per octave up to 2000 Hz and by 3 dB per octave at higher frequencies.
Selon une autre caractéristique de l'invention, le film plastique est associé à au moins un film autre apportant notamment des propriétés additionnelles que 25 celles assurant le feuilletage. According to another characteristic of the invention, the plastic film is associated with at least one other film providing, in particular, additional properties than those ensuring the lamination.
Avantageusement, l'une au moins des feuilles de verre du vitrage comporte au moins un revêtement fonctionnel. Advantageously, at least one of the glass sheets of the glazing comprises at least one functional coating.
Selon un mode de réalisation du vitrage, il comporte un panneau de verre simple d'une épaisseur de 3 mm, et un panneau de verre feuilleté avec deux 30 feuilles de verre de 2,1 mm chacune d'épaisseur. According to one embodiment of the glazing, it comprises a single glass panel with a thickness of 3 mm, and a laminated glass panel with two glass sheets of 2.1 mm each of thickness.
Selon un second mode de réalisation du vitrage, il comporte un panneau de verre simple d'une épaisseur de 4 mm, et un panneau de verre feuilleté avec deux feuilles de verre de 1,6 mm chacune d'épaisseur. According to a second embodiment of the glazing, it comprises a single glass panel with a thickness of 4 mm, and a laminated glass panel with two glass sheets each of 1.6 mm thick.
Selon un troisième mode de réalisation du vitrage, il comporte un panneau de verre simple d'une épaisseur de 4 mm, et un panneau de verre feuilleté avec deux feuilles de verre de 2,1 mm chacune d'épaisseur. According to a third embodiment of the glazing, it comprises a single glass panel with a thickness of 4 mm, and a laminated glass panel with two glass sheets of 2.1 mm each thickness.
D'une manière générale, les vitrages selon l'invention sont de dimensions inférieures à 2 m2 et sont destinés à équiper des bâtiments ou des véhicules, tels que des vitrages d'automobiles. In general, the glazings according to the invention are smaller than 2 m 2 and are intended to equip buildings or vehicles, such as automobile windows.
D'autres avantages et caractéristiques de l'invention vont à présent être décrits plus en détail en regard des dessins annexés sur lesquels: la figure 1 représente un vitrage multiple selon l'invention; lo - la figure 2 illustre les courbes d'indice d'affaiblissement acoustique de différents vitrages de l'invention et d'un vitrage isolant de référence. Other advantages and features of the invention will now be described in more detail with reference to the accompanying drawings in which: FIG. 1 represents a multiple glazing unit according to the invention; FIG. 2 illustrates the sound reduction index curves of various glazings of the invention and a reference insulating glazing unit.
Le vitrage multiple 1 illustré sur la figure 1 comporte un panneau de verre feuilleté 10 et un panneau de verre simple 20, ces panneaux étant séparés par une lame de gaz 30 telle qu'une lame d'air, est assemblés de manière étanche à l'aide de moyens connus de l'homme du métier. The multiple glazing 1 illustrated in FIG. 1 comprises a laminated glass panel 10 and a single glass panel 20, these panels being separated by a gas blade 30 such as an air knife, are assembled in a watertight manner. using means known to those skilled in the art.
Le panneau de verre simple 20 a une épaisseur comprise entre 3 et 5 mm. Le panneau de verre feuilleté est constitué d'au moins deux feuilles de verre 11 et 12 séparées et rendues solidaires d'une feuille en matière plastiquel3. Chaque feuille de verre présente une épaisseur comprise entre 1,5 et 2,5 mm. The single glass panel 20 has a thickness of between 3 and 5 mm. The laminated glass panel consists of at least two sheets of glass 11 and 12 separated and made integral with a sheet of plastic material. Each glass sheet has a thickness of between 1.5 and 2.5 mm.
La feuille 13 présente une épaisseur d'au moins 0,38 mm. Cette feuille est par exemple en polyvinylbutyral (PVB) à propriétés d'isolement acoustique améliorées, ou en PVB normal ne présentant pas de telles propriétés d'isolement acoustique. The sheet 13 has a thickness of at least 0.38 mm. This sheet is for example polyvinyl butyral (PVB) with improved acoustic insulation properties, or normal PVB does not have such acoustic insulation properties.
Bien entendu, le vitrage peut comprendre sur l'une ou plusieurs des feuilles de verre le constituant des revêtements fonctionnels du type couches minces, par exemple, pour une protection anti-rayures, une protection contre les UV, une coloration du vitrage. En outre, le film plastique 13 peut être associé à au moins un film autre apportant notamment des propriétés additionnelles (couleurs, anti- UV, diffusion de la lumière, etc...). Of course, the glazing may comprise, on one or more of the glass sheets constituting functional coatings of the thin-film type, for example, for anti-scratch protection, UV protection, coloring of the glazing. In addition, the plastic film 13 may be associated with at least one other film including additional properties (colors, anti-UV, light diffusion, etc ...).
Le vitrage de l'invention présente des propriétés d'isolement acoustique équivalentes ou sensiblement équivalentes, c'est-à-dire ne dépassant pas un écart de 1 dB en indice d'affaiblissement acoustique, à un vitrage isolant usuel de référence qui comprend au moins deux feuilles de verre séparées par une lame de gaz identique à la lame de gaz 30, le poids du vitrage de l'invention étant inférieur d'au moins 30 % au poids du vitrage isolant de référence, de préférence inférieure d'au moins 40%. On notera que le poids de l'intercalaire est considéré comme négligeable. The glazing unit of the invention has equivalent or substantially equivalent acoustic insulation properties, that is to say not exceeding a difference of 1 dB in the sound reduction index, to a standard insulating glazing unit which comprises at least two glass sheets separated by a blade of gas identical to the gas strip 30, the weight of the glazing unit of the invention being at least 30% less than the weight of the reference insulating glass, preferably less than 40%. It should be noted that the weight of the interlayer is considered negligible.
Le vitrage isolant de référence n 0 est un vitrage du type 4 (12) 10, c'est-à-dire comportant une feuille de verre de 4 mm, une lame de gaz de 12 mm et une feuille de verre de 10 mm. The insulating glazing unit of reference No. 0 is a type 4 glazing (12) 10, that is to say comprising a 4 mm glass sheet, a 12 mm gas plate and a 10 mm glass sheet.
Ce vitrage de référence est particulièrement performant car présentant un io indice d'affaiblissement acoustique pondéré Rw de 38 dB, en comparaison à un vitrage isolant de même constitution mais avec des feuilles de verre de 3 mm et une lame de gaz d'épaisseur identique, pour lequel l'indice d'affaiblissement RW n'est que de 32 dB. This reference glazing is particularly efficient because it has a Rw-weighted sound reduction index of 38 dB, compared to an insulating glazing unit of the same constitution but with 3 mm glass sheets and a gas strip of identical thickness. for which the RW attenuation index is only 32 dB.
On rappelle que l'indice d'affaiblissement acoustique est mesuré selon la norme ISO-140 dans une installation conforme à ladite norme sur des échantillons de vitrage de dimensions 800 mm x 500 mm, et l'indice pondéré RW calculé ensuite selon la norme ISO-717. It is recalled that the sound reduction index is measured according to the ISO-140 standard in an installation conforming to the said standard on glazing samples of dimensions 800 mm × 500 mm, and the weighted index RW subsequently calculated according to the ISO standard. -717.
Des exemples de vitrage de l'invention sont les suivants: É Le vitrage n 1 est du type 3 (12) 2,1-2,1: il comprend une feuille de verre 20 20 de 3 mm, une lame de gaz 30 de 12 mm, deux feuilles de verre 11 et 12 du feuilleté de 2,1 mm chacune d'épaisseur séparées par une feuille de PVB à propriétés d'isolement acoustique améliorées de 0,38 mm d'épaisseur. Examples of glazing of the invention are as follows: # 1 glazing is of type 3 (12) 2.1-2.1: it comprises a glass sheet 20 of 3 mm, a blade of gas 30 12 mm, two sheets of glass 11 and 12 laminated 2.1 mm each of thickness separated by a PVB sheet with acoustic insulation properties of 0.38 mm thick.
Dans la suite de la description, les vitrages de l'invention sont référencés de cette manière, la feuille en PVB de séparation du feuilleté présentant une 25 épaisseur de 0,38 mm. In the remainder of the description, the glazings of the invention are referenced in this way, the laminar PVB separation sheet having a thickness of 0.38 mm.
É Le vitrage n 2 est du type 4 (12) 1,6-1,6 avec du PVB à propriétés d'isolement acoustique améliorées. É Glazing n 2 is type 4 (12) 1.6-1.6 with PVB with improved acoustic insulation properties.

Le tableau ci-après résume, pour chacun des vitrages n 1 à n 5 et pour le vitrage de référence n 0 les valeurs d'indice d'affaiblissement acoustique pondéré et la réduction en pourcentage de poids des vitrages de l'invention par rapport au vitrage de référence. The table below summarizes, for each of the glazings n 1 to n 5 and for the glazing of reference n 0, the weighted sound reduction index values and the reduction in weight percentage of the glazings of the invention compared to the reference glazing.
Vitrage Indice d'affaiblissement Rw (dB) Réduction en % de poids N 0 38 N 1 37 48,6 % N 2 38 48,6 % N 3 38 41,4% N 4 37 41,4% N 5 36 55,7 % On constate qu'en réduisant le poids du vitrage de plus de 30%, voire d'au moins 40%, par rapport au poids d'un vitrage isolant usuel de référence, on obtient un indice d'affaiblissement acoustique tout aussi comparable. On pourra préférer les vitrages du type N 2 ou N 3 comportant le verre simple de 4 mm et incluant du PVB à propriétés d'isolement acoustique améliorées. Glazing Index of weakening Rw (dB) Reduction in% of weight N 0 38 N 1 37 48.6% N 2 38 48.6% N 3 38 41.4% N 4 37 41.4% N 5 36 55, 7% It can be seen that by reducing the weight of the glazing by more than 30%, or even by at least 40%, compared to the weight of a standard insulating glazing unit, an equally comparable sound reduction index is obtained. . N 2 or N 3 types of glass with 4 mm single glass and including PVB with improved acoustic insulation properties may be preferred.
Par ailleurs, les épaisseurs de verre du panneau de verre simple (de 3 à io 5 mm) et du panneau de verre feuilleté (de deux fois 1,5 mm à deux fois 2,5 mm) sont telles que le plus grand rapport des extrema est égal à 1,7 (soit 5/(2x1,5) ou soit (2x2,5)/3). Par conséquent, le déséquilibre en poids d'un côté du vitrage par rapport à l'autre côté n'excède pas un facteur 2, alors que par exemple le vitrage de référence présente un rapport de déséquilibre de 2,5 (10/4). Aussi, l'assemblage du panneau de verre simple au panneau de verre feuilleté est plus commode, il n'y a pas nécessité à positionner le panneau le plus lourd en dessous et à attendre que l'ensemble des joints assurant l'étanchéité et la tenue mécanique soit fini de poser. En outre, la manipulation du vitrage est plus facile. On the other hand, the glass thicknesses of the single glass panel (3 to 5 mm) and the laminated glass panel (twice 1.5 mm to 2 × 2.5 mm) are such that the largest ratio of extrema is equal to 1.7 (ie 5 / (2x1.5) or (2x2.5) / 3). Therefore, the imbalance in weight of one side of the glazing with respect to the other side does not exceed a factor 2, whereas for example the reference glazing has an unbalance ratio of 2.5 (10/4) . Also, the assembly of the single glass panel to the laminated glass panel is more convenient, there is no need to position the heavier panel underneath and to wait for all the joints ensuring the seal and the mechanical strength is finished laying. In addition, the manipulation of the glazing is easier.
