Definitions
- the invention relates to an insulating frame with concealed opening for multiple glazing, adapted to equip a passive building.
- the document DE 199 21 698 discloses a multi-glazed window in which the timber of the frame and the sash is insulated externally by an agglomerate of polyurethane residues. This thermal insulation is much less effective than rigid foams polyurethane and the like, which have a cellular structure. In addition, it is not protected against mechanical stresses such as scratches and shocks, or against weather and UV rays.
- window frames provided with a protective cover for thermal insulation are disclosed in particular in the following documents: DE 101 42 703 , EP 0865 559 , EP 1 178 177 and EP 1 221 525 .
- These frames have in common the fact, firstly, to be relatively expensive because the insulation and its cover equip both the frame and the opening, and secondly to present a relatively large glazing frame, which limits the natural lighting in the dwelling.
- the document EP 0 843 768 has a window or French window with hidden opening. This solution saves thermal insulation and its protective cover on the opening and on the other hand favors natural lighting thanks to a frame of reduced space. However, thermal insulation is limited here to a simple thermal cut-off within an aluminum frame, which is insufficient to meet the conductivity standards.
- the document DE 10 2006 046 958 A1 discloses a window frame concealed opening similar to the previous, except that in this German application thermal insulation is provided under the metal cover. It is connected to the outer perimeter of the frame by means of metal fasteners which constitute as many thermal bridges detrimental to the passive character of the building concerned.
- the patent FR 1 511 055 relates to a window frame that can be used flexibly with both single glazing and double glazing without fundamental modification due to the presence of a removable rod.
- This window frame is not concealed opening and does not have thermal insulation.
- this wand is located outside the building, which exposes it to bad weather and can therefore affect its sustainability. In addition, its external position increases the risk of burglary.
- the substantives “inside” and “outside” refer respectively to the interior and exterior of the building.
- the terms “inner perimeter” and “outer perimeter” of a dormant or opening frame they refer respectively to the perimeter of the frame facing the glazing and the one facing the masonry.
- a first object of the invention is to provide an economical insulating frame to manufacture while having high thermal performance.
- Another object of the invention is to provide a flexible insulating frame for use and being part of sustainable development.
- the advantage of the invention is that the prefabrication of the opening frames can be done in large series, regardless of the thickness of the glazing.
- This increase in productivity is due to the flexibility introduced into the manufacturing by the design of the glazing beads: glazing differing only in thickness can be mounted on identical opening frames, the width of the glazing only to be adapted to the thickness glazing.
- the glazing stops are also provided inside the building, which shelters them from bad weather, promotes their life and reduces the risk of break-ins.
- the use of the hidden opening technique also significantly reduces manufacturing costs by reducing the material costs implemented; the fact that the doors are hidden reduces their exposure to the weather and allows one hand to provide an insulation and a protective cover only on the frame, thus saving insulation and metal, and secondly to use less noble wood species and therefore less expensive for an equivalent life.
- the insulating frame of the invention also has the advantage of contributing to sustainable development not only by its thermal characteristics, but also through the use of natural materials such as wood.
- By the technique of the hidden opening can be used for example spruce wood, a gasoline that has the advantage of rapid growth.
- the frame according to the invention when the frame according to the invention is closed, it has, on the side exposed to the elements a metal frame (easy to maintain and not requiring coating) and, on the inside side of the house, a wooden frame (with a warmer appearance).
- the ease of maintenance of the chassis is a guarantee of long life.
- the glazing can be exchanged later against another more efficient, by replacing or reworking only the bead. A user can therefore follow the rapid technological development of passive glazing without having to scrap all of his chassis.
- the insulating frame according to the invention makes it possible to obtain a larger glass surface for the same total area of the frame and thus to give the house a better natural lighting.
- the insulating material is in the form of one or more profiles.
- the cross section of the profile can be calculated so as to be applied without gaps between the metal cover and against the face of the frame facing outwards, which makes it possible in particular to ensure that the performance of the insulation implemented in accordance with its advertised characteristics.
- mass prefabrication of these profiles results in productivity gains.
- the profiles can be extruded or, advantageously, milled.
- the insulating material is a polyurethane foam.
- Polyurethane foam is a cellular insulation composed of thin cells that store an insulating gas and therefore has an extremely low thermal conductivity ⁇ whose order of magnitude is between 0.022 and 0.028 W / (mK).
- the cover covering the frame is made of a material chosen from aluminum, anodized aluminum, lacquered aluminum and stainless steel. These materials combine the advantage of presenting a particularly aesthetic appearance with that of easy maintenance.
- the cover covering the frame is preferably connected to the wooden profile of the frame through one or more fasteners of synthetic material. This arrangement avoids thermal bridges.
- the frame according to the invention comprises at least one fixed glass part.
- the multiple glazing of the frame according to the invention comprises at least one laminated glass.
- the laminated glass comprises at least two glass slides glued together by at least one interlayer of plastic material, such as polyvinyl butyral. This layer absorbs part of the energy of a possible impact on the one hand and on the other hand holds in place the fragments of glass that result from this impact.
- Glazing according to the invention, which are equipped with laminated glass thus combine energy efficiency with the protection of property against the risk of burglary, and that of people against the risk of cutoff etc.
- the Fig. 1 shows an insulating frame 1 according to the invention which comprises a frame 2 and an opening 4.
- the frame 2 comprises a wooden section 3 which bears on its outwardly facing face a cover 10 made of a metal profile, such as aluminum.
- the cover 10 surrounds a section of insulating material 9, such as a polyurethane foam, bonded to the outer face of the wooden section 3.
- the opening 4 comprises a wooden section supporting a triple glazing 5.
- the face of this outwardly facing profile is in the same plane as the face of the glazing 5 facing outwards.
- the glazing 5 is thus supported throughout its thickness.
- the face of the glazing 5 turned inwards is fixed by a first gluing means 23 to a bead 7 made of wood, which is in turn fixed to the wooden profile of the opening 4 by a second gluing means 25.
- the bead 7 and the wooden section of the opening 4 each comprise grooves constituting mutual wedging and alignment means 21,22.
- the bonding means 23,25 solidarize while thermally insulating, unlike other fastening means such as metal screws. Being applied between two surfaces, they can withstand significant shear forces generated in particular by the thrust of the wind (lateral forces) and a differential thermal expansion compared to the glazing, while allowing disassembly of the bead quickly enough in case of replacement of the glazing for reasons of breakage or improvement of thermal performance or other.
- the splines also participate in the recovery of lateral shear forces due to the wind.
- the decompression chamber 8 delimited by the two keys 13,17 also forms a drainage zone. Its outer wall 11 and part 15 located on the inner perimeter side of the frame 2, gutter-shaped are formed of an impermeable material which is preferably a polymer such as santoprene. This material prevents moisture on the one hand to diffuse through the insulator 9 (and thus to alter its thermal properties), and on the other hand to penetrate into the wooden profile 3 of the frame 2 (and therefore to provoke its putrefaction). This last phenomenon is also avoided, as explained above, by the absence of direct contact between the hood 10 of the insulating material 9 and the wooden profile 3 of the frame 2.
- the decompression chamber 8 opens at its low point on a drainage channel 12 in communication with the outside atmosphere.
- the channel 12 may be provided at its mouth outside a cover 14 protecting it from the dynamic pressure of the wind.
- the wood of the frame 2 and the opening 4 is protected inside by a vapor barrier (not visible in the figure).
- the water vapor contained in the atmosphere of the house will therefore be prevented from entering the wood, in which it may condense.
- the vapor barrier may be for example a paint or varnish.
- the metal cap 10 and the baffle 7 culminate substantially at the same height, so that the opening is "hidden", that is to say not visible from the outside.
- the advantages that are related to this design include in particular a better natural lighting inside the home for the same total surface of the frame 1.
- the opening having no visible outer surface, it can be used. use less noble wood species such as spruce and therefore less expensive for an equivalent life.

Description
L'invention se rapporte à un châssis isolant à ouvrant caché pour vitrage multiple, apte à équiper un bâtiment passif.The invention relates to an insulating frame with concealed opening for multiple glazing, adapted to equip a passive building.
Dans le cadre des démarches visant à assurer un développement durable et donc à économiser les ressources naturelles, en particulier dans le bâtiment, des normes pour maisons dites passives ont été élaborées. Afin de répondre à ces normes, il est généralement fait usage d'une combinaison de techniques comprenant des panneaux solaires, une isolation thermique très performante, une ventilation adaptée avec récupération de chaleur sur l'air vicié, l'utilisation des gains de chaleur internes ainsi qu'une technologie de fenêtre avancée.As part of efforts to ensure sustainable development and thus to save natural resources, especially in the building sector, standards for so-called passive houses have been developed. In order to meet these standards, it is generally used a combination of techniques including solar panels, high performance thermal insulation, adequate ventilation with heat recovery on stale air, the use of internal heat gains as well as advanced window technology.
En particulier dans le cas des fenêtres ou portes-fenêtres, le respect des normes passives implique l'adoption de valeurs de coefficient de transfert de chaleur U fort basses allant typiquement de 0,85 à 0,70 W/(m2.K) pour l'entièreté de la fenêtre y compris son encadrement. Ces valeurs résultent de la combinaison d'un vitrage multiple (généralement au moins triple) avec une excellente étanchéité à l'air et des châssis à coupure thermique particulièrement efficace.Particularly in the case of windows or French windows, compliance with passive standards implies the adoption of very low values of U-heat transfer coefficient typically ranging from 0.85 to 0.70 W / (m 2 .K). for the entire window including its frame. These values result from the combination of multiple glazing (usually at least triple) with excellent airtightness and particularly efficient thermal cutoff frames.
Malgré les progrès considérables accomplis ces dernières années dans le domaine des fenêtres et les subsides octroyés par les pouvoirs publics, les châssis passifs demeurent relativement onéreux.Despite the considerable progress made in recent years in the field of windows and subsidies granted by the public authorities, passive frames remain relatively expensive.
Afin de rendre la technique passive financièrement plus accessible, les fabricants de châssis s'efforcent en permanence de réduire leurs coûts de production.In order to make passive technology financially more accessible, chassis manufacturers are constantly striving to reduce their production costs.

Le besoin demeure donc quant à un châssis isolant à ouvrant caché, durable, économique à fabriquer et flexible d'utilisation, tout en étant apte à être mis en oeuvre dans un bâtiment passif.The need therefore remains as to an insulating frame with hidden sash, durable, economical to manufacture and flexible use, while being able to be implemented in a passive building.
Dans la présente demande, les substantifs « intérieur » et « extérieur » se rapportent respectivement à l'intérieur et à l'extérieur du bâtiment. Quant aux termes « périmètre intérieur » et « périmètre extérieur» d'un cadre dormant ou ouvrant, ils se réfèrent respectivement au périmètre du cadre faisant face au vitrage et à celui orienté vers la maçonnerie.In this application, the substantives "inside" and "outside" refer respectively to the interior and exterior of the building. As for the terms "inner perimeter" and "outer perimeter" of a dormant or opening frame, they refer respectively to the perimeter of the frame facing the glazing and the one facing the masonry.
Un premier but de l'invention est de procurer un châssis isolant économique à fabriquer tout en présentant de hautes performances thermiques.A first object of the invention is to provide an economical insulating frame to manufacture while having high thermal performance.
Un autre but de l'invention est de procurer un châssis isolant flexible d'utilisation et s'inscrivant dans le développement durable.Another object of the invention is to provide a flexible insulating frame for use and being part of sustainable development.
L'invention est telle que définie dans la revendication principale et comporte un châssis isolant à ouvrant caché pour vitrage multiple, comprenant un dormant et au moins un ouvrant. Sur chacun des côtés du châssis isolant :
- le dormant comprend un profilé en bois qui porte sur sa face tournée vers l'extérieur un capot formé d'un profilé métallique, le dit capot entourant un matériau isolant collé sur la face extérieure du profilé en bois, sans aucun contact direct avec ce dernier ;
- l'au moins un ouvrant comprend un profilé en bois supportant un vitrage multiple, la face de ce profilé tournée vers l'extérieur étant dans le même plan que la face du vitrage tournée vers l'extérieur;
- la face du vitrage tournée vers l'intérieur est fixée par un premier moyen de collage à une parclose en bois intérieure ;
- la parclose et le profilé en bois de l'ouvrant comprennent des moyens de calage et d'alignement mutuels ;
- la parclose est fixée au profilé en bois de l'ouvrant par un deuxième moyen de collage ;
- la face du vitrage tournée vers l'extérieur constitue une première frappe sur le dormant;
- la face du profilé en bois de l'ouvrant située du côté de son périmètre extérieur comprend des profils formant au moins une deuxième et troisième frappe sur le dormant.
- the frame includes a wooden section which carries on its side facing outwardly a hood formed of a metal profile, said hood surrounding an insulating material bonded to the outer face of the wooden profile, without any direct contact with the latter ;
- the at least one opening comprises a wooden section supporting a multiple glazing, the face of this outwardly facing section being in the same plane as the face of the glazing facing outwards;
- the face of the glazing turned inwards is fixed by a first gluing means to an interior glazing bead;
- the glazing bead and the wooden profile of the opening comprise mutual wedging and alignment means;
- the bead is attached to the wooden profile of the opening by a second gluing means;
- the face of the glazing facing outwards constitutes a first strike on the frame;
- the face of the wooden profile of the opening located on the side of its outer perimeter comprises profiles forming at least a second and third strikes on the frame.
L'avantage de l'invention est que la préfabrication des cadres ouvrants peut se faire en grande série, indépendamment de l'épaisseur du vitrage. Ce gain de productivité est dû à la souplesse introduite dans la fabrication par la conception des parcloses : des vitrages ne différant que par l'épaisseur peuvent être montés sur des cadres ouvrants identiques, la largeur seule de la parclose devant être adaptée à l'épaisseur du vitrage. Les parcloses sont en outre prévues à l'intérieur du bâtiment, ce qui les met à l'abri des intempéries, favorise leur durée de vie et diminue le risque d'effraction. D'autre part, l'utilisation de la technique de l'ouvrant caché permet également de réduire sensiblement les coûts de fabrication en diminuant les dépenses de matériaux mis en oeuvre ; le fait que les ouvrants sont cachés réduit leur exposition aux intempéries et permet d'une part de prévoir un isolant et un capot de protection uniquement sur le dormant, donc d'économiser de l'isolant et du métal, et d'autre part d'utiliser des essences de bois moins nobles et donc moins coûteuses pour une durée de vie équivalente.The advantage of the invention is that the prefabrication of the opening frames can be done in large series, regardless of the thickness of the glazing. This increase in productivity is due to the flexibility introduced into the manufacturing by the design of the glazing beads: glazing differing only in thickness can be mounted on identical opening frames, the width of the glazing only to be adapted to the thickness glazing. The glazing stops are also provided inside the building, which shelters them from bad weather, promotes their life and reduces the risk of break-ins. On the other hand, the use of the hidden opening technique also significantly reduces manufacturing costs by reducing the material costs implemented; the fact that the doors are hidden reduces their exposure to the weather and allows one hand to provide an insulation and a protective cover only on the frame, thus saving insulation and metal, and secondly to use less noble wood species and therefore less expensive for an equivalent life.
Par ailleurs, la combinaison des caractéristiques du châssis lui permettent d'atteindre d'excellentes performances en isolation thermique (le coefficient de transfert de chaleur Uf ne dépassant pas 0,642 W/(m2K)). Il est donc adapté à une intégration dans un bâtiment passif:
- On relèvera notamment la possibilité d'y monter un vitrage multiple, par exemple triple ;
- Les matériaux isolants évitent l'apparition de ponts thermiques : bois plein pour les cadres dormant et ouvrant ; isolant appliqué sur le dormant ; colles comme moyens d'assemblage ;
- Les ponts thermiques sont également évités par l'absence de contact direct entre le capot métallique et le profilé en bois du dormant ;
- Cette absence de contact empêche aussi que de l'eau se condensant sur la surface conductrice du capot métallique ne vienne mouiller le bois du dormant et donc le putréfier ;
- Les profils au droit de chacune des au moins trois frappes permettent d'assurer une très bonne l'étanchéité du châssis à l'eau et l'air.
- It will be noted in particular the possibility of mounting a multiple glazing, for example triple;
- Insulating materials avoid the appearance of thermal bridges: solid wood for sleeping and opening frames; insulation applied to the frame; glues as means of assembly;
- Thermal bridges are also avoided by the absence of direct contact between the metal cover and the wooden profile of the frame;
- This absence of contact also prevents water condensing on the conductive surface of the metal cap from wetting the wood of the frame and thus putrefying;
- The profiles at the right of each of the at least three keystrokes make it possible to ensure a very good seal of the frame with water and air.
Le châssis isolant de l'invention présente aussi l'avantage de contribuer au développement durable non seulement par ses caractéristiques thermiques, mais aussi grâce à l'utilisation de matériaux naturels tels que le bois. Par la technique de l'ouvrant caché, on peut utiliser par exemple du bois d'épicéa, une essence qui présente l'avantage d'une croissance rapide.
Par ailleurs, lorsque le châssis selon l'invention est fermé, il ne présente, du côté exposé aux intempéries qu'un cadre métallique (aisé à entretenir et ne nécessitant pas d'enduction) et, du côté de l'intérieur de l'habitation, qu'un cadre en bois (d'aspect plus chaud). La facilité d'entretien du châssis est un gage de longue durée de vie. D'autre part, le vitrage peut être échangé ultérieurement contre un autre plus performant, en ne remplaçant ou en ne retravaillant que la parclose. Un utilisateur peut donc suivre le développement technologique rapide en matière de vitrages passifs sans devoir mettre au rebut tous ses châssis.
En outre, le châssis isolant selon l'invention permet d'obtenir une plus grande
surface vitrée pour une même surface totale de châssis et donc de faire bénéficier à l'habitation d'un meilleur éclairage naturel.The insulating frame of the invention also has the advantage of contributing to sustainable development not only by its thermal characteristics, but also through the use of natural materials such as wood. By the technique of the hidden opening can be used for example spruce wood, a gasoline that has the advantage of rapid growth.
Furthermore, when the frame according to the invention is closed, it has, on the side exposed to the elements a metal frame (easy to maintain and not requiring coating) and, on the inside side of the house, a wooden frame (with a warmer appearance). The ease of maintenance of the chassis is a guarantee of long life. On the other hand, the glazing can be exchanged later against another more efficient, by replacing or reworking only the bead. A user can therefore follow the rapid technological development of passive glazing without having to scrap all of his chassis.
In addition, the insulating frame according to the invention makes it possible to obtain a larger
glass surface for the same total area of the frame and thus to give the house a better natural lighting.
Suivant un mode de réalisation préféré, le matériau isolant se présente sous la forme d'un ou plusieurs profilés. La section transversale du profilé peut être calculée de manière à s'appliquer sans interstice à la fois contre le capot métallique et contre la face du dormant tournée vers l'extérieur, ce qui permet notamment de s'assurer que les performances de l'isolation mise en oeuvre soient conformes à ses caractéristiques annoncées. En outre, la préfabrication en grande série de ces profilés entraîne des gains de productivité. Les profilés peuvent être soit extrudés, soit, avantageusement, fraisés.According to a preferred embodiment, the insulating material is in the form of one or more profiles. The cross section of the profile can be calculated so as to be applied without gaps between the metal cover and against the face of the frame facing outwards, which makes it possible in particular to ensure that the performance of the insulation implemented in accordance with its advertised characteristics. In addition, mass prefabrication of these profiles results in productivity gains. The profiles can be extruded or, advantageously, milled.
Le matériau isolant est une mousse de polyuréthane. La mousse de polyuréthane est un isolant alvéolaire, composé de fines cellules emmagasinant un gaz isolant et présente donc une conductivité thermique λ extrêmement basse dont l'ordre de grandeur se situe entre 0,022 et 0,028 W/(mK).The insulating material is a polyurethane foam. Polyurethane foam is a cellular insulation composed of thin cells that store an insulating gas and therefore has an extremely low thermal conductivity λ whose order of magnitude is between 0.022 and 0.028 W / (mK).
Suivant un mode de réalisation avantageux, le capot recouvrant le dormant est en un matériau choisi parmi l'aluminium, l'aluminium anodisé, l'aluminium laqué et l'acier inoxydable. Ces matériaux combinent l'avantage de présenter un aspect particulièrement esthétique avec celui d'une maintenance aisée.According to an advantageous embodiment, the cover covering the frame is made of a material chosen from aluminum, anodized aluminum, lacquered aluminum and stainless steel. These materials combine the advantage of presenting a particularly aesthetic appearance with that of easy maintenance.
Le capot recouvrant le dormant est de préférence relié au profilé en bois du dormant par l'intermédiaire d'une ou plusieurs fixations en matière synthétique. Cette disposition évite des ponts thermiques.The cover covering the frame is preferably connected to the wooden profile of the frame through one or more fasteners of synthetic material. This arrangement avoids thermal bridges.
Selon un autre mode de réalisation le châssis selon l'invention comprend au moins une partie vitrée fixe.According to another embodiment, the frame according to the invention comprises at least one fixed glass part.
Avantageusement, le vitrage multiple du châssis selon l'invention comprend au moins un verre feuilleté. Le verre feuilleté comprend au moins deux lames de verre collées entre elles par au moins une couche intercalaire en matière plastique, tel que le poly(butyral de vinyle). Cette couche absorbe d'une part une partie de l'énergie d'un éventuel impact et d'autre part maintient en place les fragments de verre qui résultent de cet impact. Les vitrages selon l'invention, qui sont équipés de verre feuilleté combinent donc l'efficacité énergétique avec la protection des biens contre les risques d'effraction, et celle des personnes contre les risques de coupure etc.Advantageously, the multiple glazing of the frame according to the invention comprises at least one laminated glass. The laminated glass comprises at least two glass slides glued together by at least one interlayer of plastic material, such as polyvinyl butyral. This layer absorbs part of the energy of a possible impact on the one hand and on the other hand holds in place the fragments of glass that result from this impact. Glazing according to the invention, which are equipped with laminated glass thus combine energy efficiency with the protection of property against the risk of burglary, and that of people against the risk of cutoff etc.
Ces aspects ainsi que d'autres aspects de l'invention seront clarifiés dans la description détaillée ci-après d'un mode de réalisation particulier donné à titre d'exemple non limitatif de l'invention, référence étant faite au dessin, dans lequel :
-
Fig.1 est une vue d'une coupe transversale d'une variante préférée du châssis selon l'invention.

Fig.1 is a view of a cross section of a preferred embodiment of the frame according to the invention.
La
Le dormant 2 comprend un profilé en bois 3 qui porte sur sa face tournée vers l'extérieur un capot 10 constitué d'un profilé métallique, tel que l'aluminium. Le capot 10 entoure un profilé en matériau isolant 9, tel qu'une mousse de polyuréthane, collé sur la face extérieure du profilé en bois 3.The frame 2 comprises a
L'ouvrant 4 comprend un profilé en bois supportant un triple vitrage 5. La face de ce profilé tournée vers l'extérieur se trouve dans le même plan que la face du vitrage 5 tournée vers l'extérieur. Le vitrage 5 est ainsi soutenu sur toute son épaisseur. En outre, la face du vitrage 5 tournée vers l'intérieur est fixée par un premier moyen de collage 23 à une parclose 7 en bois, laquelle est fixée à son tour au profilé en bois de l'ouvrant 4 par un deuxième moyen de collage 25. Par ailleurs, la parclose 7 et le profilé en bois de l'ouvrant 4 comprennent chacun des cannelures constituant des moyens de calage et d'alignement mutuels 21,22. Ces particularités de construction coopèrent pour assurer la stabilité du triple vitrage, notamment au vent, dans l'ouvrant 4, ce qui contribue à l'étanchéité du châssis 1 à l'air extérieur et à l'eau des intempéries. Les moyens de collage 23,25 solidarisent tout en isolant thermiquement, contrairement à d'autres moyens de fixation tels que des vis métalliques. Etant appliqués entre deux surfaces, ils peuvent résister à d'importants efforts de cisaillement engendrés notamment par la poussée du vent (efforts latéraux) et à une dilatation thermique différentielle par rapport au vitrage, tout en permettant de démonter la parclose assez rapidement en cas de remplacement du vitrage pour des raisons de bris ou d'amélioration des performances thermiques ou autres. Outre le moyen de collage 25, les cannelures participent également à la reprise des efforts de cisaillement latéraux dus au vent.The opening 4 comprises a wooden section supporting a triple glazing 5. The face of this outwardly facing profile is in the same plane as the face of the glazing 5 facing outwards. The glazing 5 is thus supported throughout its thickness. In addition, the face of the glazing 5 turned inwards is fixed by a first gluing means 23 to a
Une triple barrière (ou frappe) est visible sur la figure de façon à assurer une parfaite étanchéité:
- une première frappe 13 empêche au maximum le passage d'eau lors d'intempéries (par ruissellement le long de la surface vitrée et/ou par la pression due au vent) ;
- une deuxième frappe 17 referme une chambre de décompression 8. En assurant une étanchéité à l'air extérieur, elle contribue également à l'isolation thermique du châssis 1;
- une troisième frappe 19 améliore en outre l'isolation acoustique du châssis 1.
- a
first strike 13 prevents the maximum passage of water during bad weather (by runoff along the glass surface and / or by the pressure due to wind); - a
second strike 17 closes adecompression chamber 8. By providing a seal to the outside air, it also contributes to the thermal insulation of the frame 1; - a
third strike 19 further improves the acoustic insulation of the frame 1.
La chambre de décompression 8 délimitée par les deux frappes 13,17 forme également une zone de drainage. Sa paroi externe 11 et sa partie 15 située du côté du périmètre intérieur du dormant 2, en forme de gouttière sont formées d'un matériau imperméable qui est de préférence un polymère tel que le santoprène. Ce matériau empêche l'humidité d'une part de diffuser à travers l'isolant 9 (et donc d'altérer ses propriétés thermiques), et d'autre part de pénétrer dans le profilé en bois 3 du dormant 2 (et donc de provoquer sa putréfaction). Ce dernier phénomène est également évité, comme exposé ci-avant, par l'absence de contact direct entre le capot métallique 10 du matériau isolant 9 et le profilé en bois 3 du dormant 2. La chambre de décompression 8 débouche à son point bas sur un canal de drainage 12 en communication avec l'atmosphère extérieure. Celui-ci est destiné d'une part à permettre la décompression dans la chambre 8 de l'air ou du mélange air/eau des intempéries s'y introduisant le cas échéant par la première frappe 13, et d'autre part à évacuer vers l'extérieur l'eau des intempéries qui sinon s'y accumulerait. En fonction de sa disposition, le canal 12 peut être pourvu à son embouchure à l'extérieur d'un cache 14 le protégeant de la pression dynamique du vent.The
Dans le châssis isolant 1, le bois du dormant 2 et de l'ouvrant 4 est protégé à l'intérieur par un pare-vapeur (non visible sur la figure). La vapeur d'eau contenue dans l'atmosphère de l'habitation sera donc empêchée de pénétrer dans le bois, dans lequel elle risque de se condenser. Le pare-vapeur peut être par exemple une peinture ou un vernis.In the insulating frame 1, the wood of the frame 2 and the opening 4 is protected inside by a vapor barrier (not visible in the figure). The water vapor contained in the atmosphere of the house will therefore be prevented from entering the wood, in which it may condense. The vapor barrier may be for example a paint or varnish.
Comme on peut le voir sur la figure, le capot métallique 10 et de la parclose 7 culminent sensiblement à la même hauteur, de sorte que l'ouvrant est « caché », c'est-à-dire pas visible de l'extérieur. Pour rappel, parmi les avantages qui sont liés à cette conception on peut citer en particulier un meilleur éclairage naturel à l'intérieur de l'habitation pour une même surface totale du châssis 1. L'ouvrant ne présentant aucune surface extérieure visible, on peut utiliser des essences de bois moins nobles telles que l'épicéa et donc moins coûteuses pour une durée de vie équivalente.As can be seen in the figure, the
