Durch das Anordnen einer Anzahl an Hohlkammern hintereinander in der Wärmedurchgangsrichtung durch das Profil, d.h. von der raumseitigen Außenwand zur wetterseitigen Außenwand, wird in solchen Kunststofffenstern und Kunststofftüren eine hohe thermische Isolierung erzielt. Hollow-chamber profiles made of thermoplastic material are widely used for the production of plastic windows and plastic doors. These profiles are predominantly made by extrusion from rigid PVC (PVC-U). They usually have several hollow chambers, which are delimited from each other by inner webs. By arranging a number of hollow chambers one behind the other in the heat transfer direction through the profile, i. from the room-side outer wall to the weather-side outer wall, high thermal insulation is achieved in such plastic windows and plastic doors.
Allerdings ist man durch das Erhöhen der Anzahl an Kammern, die in dem Profil in der Wärmedurchgangsrichtung hintereinander angeordnet sind, an die Grenzen gestoßen, so dass auf diese Weise nur mehr eine geringfügige weitere Verbesserung der durch ein ent- sprechendes Kunststofffenster oder eine entsprechende Kunststofftür erzielten thermi- schen Isolierung zu erreichen ist. However, by increasing the number of chambers arranged one behind the other in the profile in the heat transmission direction, the limits have been reached, so that only a slight further improvement has been achieved by a corresponding plastic window or a corresponding plastic door thermal insulation can be achieved.
An dieser Stelle setzt die vorliegende Erfindung ein, der die Aufgabe zugrunde liegt, ein Hohlkammerprofil für ein Fenster oder eine Tür zur Verfügung zu stellen, das die Nachteile des Stands der Technik überwindet. Insbesondere soll das erfindungsgemäße Hohlkam- merprofil für ein Fenster oder eine Tür verbesserte thermische Isolierungseigenschaften besitzen. Darüber hinaus liegt die Aufgabe der vorliegenden Erfindung in der Bereitstellung einer Rahmenbaugruppe für ein Fenster oder für eine Tür, die mindestens einen Profilab- schnitt eines derartigen Hohlkammerprofils umfasst. Diese und andere Aufgaben werden erfindungsgemäß durch ein Hohlkammerprofil mit den Merkmalen des Anspruchs 1 oder durch eine Rahmenbaugruppe mit den Merkmalen des Anspruchs 14 gelöst. Bevorzugte Ausführungsformen der vorliegenden Erfindung sind in den abhängigen Ansprüchen beschrieben. At this point, the present invention, which is based on the object to provide a hollow chamber profile for a window or a door, which overcomes the disadvantages of the prior art. In particular, the hollow chamber profile according to the invention should have improved thermal insulation properties for a window or a door. In addition, the object of the present invention is to provide a frame assembly for a window or for a door, which comprises at least one profile section of such a hollow chamber profile. These and other objects are achieved by a hollow chamber profile with the features of claim 1 or by a frame assembly with the features of claim 14. Preferred embodiments of the present invention are described in the dependent claims.
Gemäß der vorliegenden Erfindung wurde überaschenderweise erkannt, dass der Wärme- durchgang durch ein Hohlkammerprofil dadurch signifikant reduziert werden kann, wenn eine der Innenwände oder der Außenwände des Hohlkammerprofils mit einer niedrigemit- tierenden Beschichtung oder einer niedrigemittierenden Folie versehen ist. Niedrigemittie- rende Beschichtungen (auch als„Low-e-Beschichtungen“ bezeichnet) und niedrigemittie- renden Folien (auch als„Low-e-Folien“ bezeichnet) weisen bei hohem Transmissiongrad im sichtbaren Teil des elektromagnetischen Spektrums im infraroten Spektralbereich eine ho- he Reflexion und damit verbunden eine niedrige Emissivität (low emissivity) auf. Dement- sprechend haben niedrigemittierende Beschichtungen und niedrigemittierende Folien den Effekt, den Emissionsgrad im Wellenlängenbereich von 3 pm bis 50 pm, insbesondere im Bereich des Maximums der Wärmestrahlung bei Raumtemperatur (etwa 10 pm) abzusen- ken. Dadurch wirken sie als gute Reflektoren für Wärmestrahlung bei Raumtemperatur und können in Hohlkammerprofilen wirksam zur Verbesserung der Wärmedämmung eingesetzt werden. In derartigen niedrigemittierenden Beschichtungen und niedrigemittierenden Folien dienen Metallschichten, beispielsweise Aluminium-, Silber-, Gold-, und/oder Kupferschich- ten zur Erzeugung der hohen Reflexion im infraroten Spektralbereich. Die Metallschichten können eine Dicke im Bereich von 5 nm bis 200 pm, vorzugsweise im Bereich von 10 nm bis 25 nm aufweisen. Ebenso können Schichten, die entsprechende Metalloxide mit ent- sprechender Dicke enthalten, zum Einsatz kommen. Diese emissionsverringernden Schich- ten sind bevorzugt mit einer Schutzschicht (insbesondere mit antioxidativer Wirkung), einer Dekorschicht, einer Farbschicht, einer Lackschicht, einer Funktionsschicht (beispielsweise einer Schicht mit geringer Oberflächenspannung, z. B. easy-to-clean) sowie Kombinationen der genannten Schichten in einer oder mehreren Schichten überzogen. Surprisingly, according to the present invention, it has been found that the heat transmission through a hollow chamber profile can be significantly reduced if one of the inner walls or the outer walls of the hollow chamber profile is provided with a low-emitting coating or a low-emitting film. Low-emissivity coatings (also referred to as "low-e coatings") and low-emissivity films (also referred to as "low-e films") have a high level of transmission in the visible part of the electromagnetic spectrum in the infrared spectral range Reflection and associated low emissivity (low emissivity) on. Accordingly, low-emissivity coatings and low-emittance films have the effect of lowering the emissivity in the wavelength range from 3 pm to 50 pm, in particular in the region of the maximum of heat radiation at room temperature (about 10 pm). As a result, they act as good reflectors for thermal radiation at room temperature and can be effectively used in hollow chamber profiles for improving the thermal insulation. In such low-emissivity coatings and low-etch films, metal layers such as aluminum, silver, gold, and / or copper layers serve to produce high reflectance in the infrared spectral range. The metal layers may have a thickness in the range of 5 nm to 200 μm, preferably in the range of 10 nm to 25 nm. Likewise, layers containing corresponding metal oxides with a corresponding thickness can be used. These emission-reducing layers are preferably provided with a protective layer (in particular having an antioxidant effect), a decorative layer, a color layer, a lacquer layer, a functional layer (for example a layer with a low surface tension, eg easy-to-clean) and combinations of those mentioned Layers coated in one or more layers.
Dementsprechend liegt der vorliegenden Erfindung in der Bereitstellung eines Hohlkam- merprofils für ein Fenster oder eine Tür aus thermoplastischem Kunststoff, wobei der ther- moplastische Kunststoff die Innenwände und die Außenwände des Hohlkammerprofils bil det, wobei die Innenwände und die Außenwände die Hohlkammern des Hohlkammerprofils umgeben, und sich das Hohlkammerprofil erfindungsgemäß dadurch auszeichnet, dass mindestens eine der Innenwände und/oder der Außenwände mit einer niedrigemittierenden Beschichtung und/oder einer niedrigemittierenden Folie versehen ist. Darüber hinaus be- zieht sich die vorliegende Erfindung auf eine Rahmenbaugruppe für ein Fenster oder eine Tür, die mindestens einen Profilabschnitt eines erfindungsgemäßen Hohlkammerprofils umfasst. Accordingly, the present invention resides in the provision of a hollow chamber profile for a window or door made of thermoplastic material, wherein the thermoplastic plastic forms the inner walls and the outer walls of the hollow chamber profile, wherein the inner walls and the outer walls surround the hollow chambers of the hollow chamber profile, and the hollow chamber profile according to the invention is characterized in that at least one of the inner walls and / or the outer walls with a low-emitting Coating and / or a low-emitting film is provided. Moreover, the present invention relates to a frame assembly for a window or a door comprising at least one profile section of a hollow chamber profile according to the invention.
Erfindungsgemäß hat es sich als günstig erwiesen, wenn die niedrigemittierende Beschich- tung und/oder die niedrigemittierende Folie in einem Winkel zur Wärmedurchgangsrichtung des erfindungsgemäßen Hohlkammerprofils im Verwendungszustand, d. h. in dem in eine Wand eines Gebäudes eingebauten Zustand eines Fensters oder einer Tür, in der ein Pro- filabschnitt des erfindungsgemäßen Hohlkammerprofils eingesetzt ist, angeordnet ist, der im Bereich von 70° bis 110°, vorzugsweise 80° bis 100° liegt und besonders bevorzugt na- he 90° liegt. Die Wärmedurchgangsrichtung durch das erfindungsgemäße Hohlkammerpro- fil verläuft dabei von der raumseitigen Außenwand zur wetterseitigen Außenwand. According to the invention, it has proved to be advantageous if the low-emitting coating and / or the low-emitting film at an angle to the heat transfer direction of the hollow chamber profile according to the invention in the use state, d. H. in which installed in a wall of a building state of a window or a door in which a profile section of the profiled hollow profile according to the invention is used, is arranged, which is in the range of 70 ° to 110 °, preferably 80 ° to 100 °, and particularly preferred near 90 °. The heat transfer direction through the hollow chamber profile according to the invention extends from the room-side outer wall to the outer wall on the weather-side.
Hinsichtlich des erfindungsgemäßen Hohlkammerprofils kann es bevorzugt sein, wenn die raumseitige Außenwand des Hohlkammerprofils mit einer niedrigemittierenden Beschich- tung und/oder einer niedrigemittierenden Folie versehen ist. Dadurch wird ein großer Teil der Wärmestrahlung zurück in den Raum reflektiert, so dass die thermischen Isolierungsei- genschaften des Fensters/ der Tür stark verbessert sind. With regard to the hollow chamber profile according to the invention, it may be preferred if the room-side outer wall of the hollow chamber profile is provided with a low-emitting coating and / or a low-emitting film. As a result, a large part of the heat radiation is reflected back into the room, so that the thermal insulation properties of the window / door are greatly improved.
Es kann auch bevorzugt sein, wenn das Hohlkammerprofil einen Außenüberschlag, eine Glasleistennnut zur Aufnahme einer Glasleiste sowie einen zwischen dem Außenüber- schlag und der Glasleistennnut gebildeten Falzgrund umfasst, wobei die dem Falzgrund zugewandte Außenwand des Außenüberschlags und/oder die dem Falzgrund zugewandte Außenwand der Glasleistennut mit einer niedrigemittierenden Beschichtung und/oder einer niedrigemittierenden Folie versehen ist/sind. Ein großer Teil des Wärmedurchgangs durch ein Fenster oder eine Tür entfällt auf diesen Falzbereich, so dass der Einsatz der niedrig emittierenden Beschichtung und/oder der niedrigemittierenden Folie eben dort besonders effektiv ist. In diesem Zusammenhang trägt zur reflektierenden Ausstattung des Falzbe- reichs bei, wenn der Falzgrund profilaußenseitig mit einer niedrigemittierenden Beschich- tung und/oder einer niedrigemittierenden Folie versehen ist. Dabei ist es bevorzugt, wenn die niedrigemittierende Beschichtung und/oder die niedrigemittierende Folie im Bereich des Falzgrunds unterbrochen ist. Diese Unterbrechung soll Querleitungseffekte verhindern. Zusätzlich oder alternativ dazu kann auch in die Glasleistennut eine Glasleiste aufgenom- men sein und die dem Falzgrund zugewandte Wandung der Glasleistennut mit einer nied- rigemittierenden Beschichtung und/oder einer niedrigemittierenden Folie versehen sein. Da die Sicht auf den Falzbereich bei einem Fenster durch die Isolierverglasung verdeckt ist, ist der Einsatz der niedrigemittierenden Beschichtung und/oder der niedrigemittierenden Folie im Falzbereich auch nach außen hin nicht zu erkennen. It may also be preferred if the hollow-chamber profile comprises an external flashover, a Glasleistennnut for receiving a glazing bead and a Falzgrund formed between the outer flashover and the Glasleistennnut, wherein the Falzgrund facing outer wall of the outer flashover and / or the Falzgrund facing outer wall of Glasleistennut is provided with a low-emitting coating and / or a low-emitting film / are. A large part of the heat transfer through a window or a door is attributable to this fold region, so that the use of the low-emitting coating and / or the low-emitting film is particularly effective there. In this context, the reflective finish of the folding area contributes when the rabbet base is provided on the profile outside with a low-emitting coating and / or a low-emitting film. It is preferred if the low-emitting coating and / or the low-emitting film in the region of the rabbet base is interrupted. This interruption should prevent cross-line effects. Additionally or alternatively, a glazing bead may also be accommodated in the glazing bead groove and the wall of the glazing bead groove facing the rebate base may be provided with a glazing bead. Rigemittierenden coating and / or a low-emitting film be provided. Since the view of the fold region is concealed by the insulating glazing in a window, the use of the low-emitting coating and / or the low-emitting film in the fold area is also not visible to the outside.
Es kann auch bevorzugt sein, wenn das Hohlkammerprofil als Flügelrahmenprofil mit einem Anschlag ausgebildet ist und die der wetterseitigen Außenwand des Hohlkammerprofils zugewandte Außenwand des Anschlags mit einer niedrigemittierenden Beschichtung und/oder einer niedrigemittierenden Folie versehen ist. Eine niedrigemittierende Beschich- tung und/oder einer niedrigemittierenden Folie an der Innenseite des Anschlags reduziert den Wärmedurchgang durch den Zwischenraum zwischen Flügelrahmen- und Blendrah- men erheblich. It may also be preferred if the hollow chamber profile is designed as a sash profile with a stop and the weather-side outer wall of the hollow chamber profile facing outer wall of the stopper is provided with a low-emitting coating and / or a low-emitting film. A low-emitting coating and / or a low-emitting film on the inside of the stop considerably reduces the heat transfer through the space between the sash frame and the frame.
Es kann auch vorteilhaft sein, wenn das Hohlkammerprofil als Flügelrahmenprofil mit einer vom Falzgrund weg weisenden Fahne ausgebildet ist und mindestens eine Außenseite der Fahne, also die der wetterseitigen Außenwand oder die der raumseitigen Außenwand des erfindungsgemäßen Hohlkammerprofils zugewandte Außenseite der Fahne, vorzugsweise sowohl die der wetterseitigen Außenwand als auch die der raumseitigen Außenwand des erfindungsgemäßen Hohlkammerprofils zugewandte Außenseite der Fahne, mit einer nied- rigemittierenden Beschichtung und/oder einer niedrigemittierenden Folie versehen ist. Eine derartige Anordnung der ebenfalls den Wärmedurchgang durch den Zwischenraum zwi- schen Flügelrahmen- und Blendrahmen erheblich. It may also be advantageous if the hollow-chamber profile is designed as a sash profile with a flag facing away from Falzgrund and at least one outer side of the flag, so the weather-side outer wall or the room-side outer wall of the hollow chamber profile facing the outside of the flag, preferably both the weather side Outer wall as well as the room-side outer wall of the hollow chamber profile according to the invention facing the outside of the flag, is provided with a low-emitting coating and / or a low-emitting film. Such an arrangement also the heat transfer through the gap between sash and frame considerably.
In bevorzugten Ausführungsformen des erfindungsgemäßen Hohlkammerprofils ist das Hohlkammerprofil als Blendrahmenprofil mit einer Mitteldichtung ausgebildet und die Au- ßenseiten der Mitteldichtung sind zumindest teilweise mit einer niedrigemittierenden Be- schichtung und/oder einer niedrigemittierenden Folie versehen. Auch hier dient die niedrig emittierende Beschichtung und/oder die niedrigemittierende Folie dazu, den Wärmedurch- gang durch den Zwischenraum zwischen Flügelrahmen- und Blendrahmen zu verringern. Dabei ist es besonders bevorzugt, wenn die niedrigemittierende Beschichtung und/oder die niedrigemittierende Folie auf einer zur raumseitigen Außenwand oder zur wetterseitigen Außenwand weisenden Seite auf die Mitteldichtung aufgebracht sind. Bei einer derartigen Anordnung stehen die niedrigemittierende Beschichtung und/oder die niedrigemittierende Folie in etwa senkrecht zur Wärmedurchgangsrichtung des erfindungsgemäßen Hohlkam- merprofils im Verwendungszustand, so dass der durch die niedrigemittierende Beschich- tung und/oder die niedrigemittierende Folie erzielte reflektierende Effekt hoch ist. In preferred embodiments of the hollow chamber profile according to the invention, the hollow chamber profile is designed as a frame profile with a center seal and the outer sides of the center seal are at least partially provided with a low-emitting coating and / or a low-emitting film. Again, the low-emissivity coating and / or the low-emissivity film serves to reduce the heat transfer through the gap between sash and frame. It is particularly preferred if the low-emitting coating and / or the low-emitting film are applied to the center seal on a side facing the room-side outer wall or the weather-side outer wall. In such an arrangement, the low-emitting coating and / or the low-emitting film are approximately perpendicular to the heat transfer direction of the hollow chamber according to the invention. in use condition, so that the reflective effect achieved by the low-emissivity coating and / or the low-emissivity film is high.
Es kann auch günstig sein, wenn das Hohlkammerprofil als Blendrahmenprofil mit an sei- ner dem Falzgrund gegenüberliegenden Seite angeordneten Rastelementen ausgebildet ist, die zumindest teilweise mit einer niedrigemittierenden Beschichtung und/oder einer niedrigemittierenden Folie versehen sind. It can also be favorable if the hollow chamber profile is designed as a frame profile with latching elements arranged on its side opposite the rabbet base, which are provided at least partially with a low-emitting coating and / or a low-emitting film.
Es kann sich auch als geeignet heraussteilen, wenn das Hohlkammerprofil eine Haupthohl- kammer aufweist, deren Innenwände zumindest teilweise mit einer niedrigemittierenden Beschichtung und/oder einer niedrigemittierenden Folie versehen sind. Dabei ist es bevor- zugt, dass das erfindungsgemäßen Hohlkammerprofil mehrteilig aufgebaut, wobei die Ein- zelteile des erfindungsgemäßen Hohlkammerprofil nach dem Aufbringen der niedrigemittie- renden Beschichtung und/oder der niedrigemittierenden Folie auf die jeweilige Innenwand oder die jeweiligen Innenwände miteinander verbunden werden, beispielsweise durch Ver- schweißen, Verkleben, Verrasten oder ähnliches. Die Haupthohlkammer eines Hohlkam- merprofils, bei der es sich üblicherweise um eine Armierungskammer handelt, in die eine Armierung für das Profil, meist eine Stahlarmierung, aufgenommen wird, ist die Hohlkam- mer des Profils, in denen die Wände am weitesten voneinander beabstandet sind. Daher ist der Effekt der Wärmestrahlung in diesen Kammern am stärksten, wodurch wiederum der durch die niedrigemittierende Beschichtung und/oder die niedrigemittierende Folie erzielte Effekt hoch ist. Dabei ist es besonders bevorzugt, wenn zwei einander gegenüberliegende Innenwände der Haupthohlkammer, insbesondere die Innenwand an der Seite der raumsei- tigen Außenwand und an der Seite der wetterseitigen Außenwand, zumindest teilweise mit einer niedrigemittierenden Beschichtung und/oder einer niedrigemittierenden Folie verse- hen sind. Bei einer derartigen Anordnung sind die niedrigemittierende Beschichtung und/oder die niedrigemittierende Folie wiederum in etwa senkrecht zur Wärmedurchgangs- richtung des erfindungsgemäßen Hohlkammerprofils im Verwendungszustand angeordnet, so dass der durch die niedrigemittierende Beschichtung und/oder die niedrigemittierende Folie erzielte reflektierende Effekt hoch ist. It may also prove to be suitable if the hollow-chamber profile has a main hollow chamber whose inner walls are at least partially provided with a low-emitting coating and / or a low-emitting film. It is preferred that the hollow chamber profile according to the invention be constructed in several parts, wherein the individual parts of the hollow chamber profile according to the invention after the application of the low-emissive coating and / or the low-emitting film on the respective inner wall or the respective inner walls are interconnected, for example by Welding, gluing, latching or the like. The main hollow chamber of a hollow chamber profile, which is usually a reinforcing chamber, into which a reinforcement for the profile, usually a steel reinforcement, is received, is the hollow chamber of the profile, in which the walls are furthest apart. Therefore, the effect of heat radiation is strongest in these chambers, which in turn makes high the effect achieved by the low-emissivity coating and / or the low-emissivity film. It is particularly preferred if two mutually opposite inner walls of the main hollow chamber, in particular the inner wall on the side of the space-side outer wall and on the side of the weather-side outer wall, are at least partially provided with a low-emitting coating and / or a low-emitting film. In such an arrangement, the low-emissivity coating and / or the low-emissivity film are again disposed approximately normal to the heat transfer direction of the hollow chamber profile of the present invention in use condition such that the reflective effect achieved by the low-emissivity coating and / or the low-emissivity film is high.
Bevorzugt kann es auch sein, dass die niedrigemittierende Beschichtung und/oder einer niedrigemittierenden Folie ein Polymermaterial mit einer Oberflächenspannung von höchs- tens 20 mN/m umfasst. Auf diese Weise werden die mit des erfindungsgemäßen Hohl- kammerprofils schmutzabweisend und sind leicht zu reinigen. Als derartige Material haben sich insbesondere Polytrifluorchlorethylen (PTFCE) und Polytetrafluorethylen (PTFE) er- wiesen. It may also be preferable for the low-emittance coating and / or a low-emittance film to comprise a polymer material having a surface tension of at most 20 mN / m. In this way, the hollow chamber profiles according to the invention become dirt-repellent and are easy to clean. As such material In particular, polytrifluorochloroethylene (PTFCE) and polytetrafluoroethylene (PTFE) were detected.
Ebenso kann es von Nutzen sein, wenn die niedrigemittierende Beschichtung und/oder die niedrigemittierende Folie an der wetterseitigen Außenwand mit einer die Wetterfestigkeit verbessernden Schicht versehen ist. Dadurch wird die Langlebigkeit des erfindungsgemä- ßen Hohlkammerprofils erhöht. Dazu kann beispielsweise ein UV-beständiger Lack, insbe- sondere auf Acryl- oder Silikonbasis, in einer Schichtdicke von etwa 1 ,5 pm bis etwa 25 pm, bevorzugt in einer Schichtdicke von etwa 2 pm bis etwa 5 pm, auf die Deckschale auf- gebracht werden. Ein derartiger Lack ist beispielsweise das Lacksystem NE0712 der neoxid GmbH. Also, it may be useful if the low-emissivity coating and / or the low-emissivity film on the weather-side outer wall is provided with a weatherability-improving layer. As a result, the longevity of the hollow chamber profile according to the invention is increased. For this purpose, for example, a UV-resistant lacquer, in particular on acrylic or silicone-based, in a layer thickness of about 1, 5 pm to about 25 pm, preferably in a layer thickness of about 2 pm to about 5 pm, on the cover shell on to be brought. Such a paint, for example, the paint system NE0712 neoxid GmbH.
Ein Beispiel für eine niedrigemittierende Beschichtung und/oder eine niedrigemittierende Folie, die in dem Hohlkammerprofil gemäß der vorliegenden Erfindung eingesetzt werden kann, ist in der DE 10 2005 025 982 B4 beschrieben, auf die hinsichtlich des Aufbaus, der Materialien und der Herstellung von niedrigemittierenden Beschichtungen und/oder niedrig emittierenden Folien hiermit explizit Bezug genommen wird. Exemplarisch kann gemäß der vorliegenden Erfindung als niedrigemittierende Folie eine low-e-Kunststofffolie (PET) vom Typ Heat Mirror® HM 55 der Firma Southgate Europe GmbH eingesetzt werden. Eine nied- rigemittierende Beschichtung kann auch in Form eines Lacks auf die Innenwände und/oder die Außenwände des Hohlkammerprofils aufgebracht worden sein. An example of a low-emissivity coating and / or a low-emissivity film that may be employed in the hollow section according to the present invention is described in DE 10 2005 025 982 B4, which relates to construction, materials, and the preparation of low-emissivity coatings and / or low-emitting films are hereby incorporated by reference. By way of example, according to the present invention, a low-e-plastic film (PET) of the type Heat Mirror® HM 55 from Southgate Europe GmbH can be used as the low-emittance film. A low-emissivity coating may also have been applied in the form of a lacquer to the inner walls and / or the outer walls of the hollow-chamber profile.

Der erhaltene Fenster- oder Türrahmen ist für den Einbau in eine Öffnung einer Wandung eines Gebäudes vorgesehen bzw. in die Öffnung der Wandung eines Gebäudes einbaubar. Das erfindungsgemäße Hohlkammerprofil sowie einzelne Teile davon können auch zeilen- weise oder schichtweise unter Verwendung eines zeilenaufbauenden oder schichtaufbau- enden Fertigungsverfahrens (z. B. 3D-Druck) hergestellt werden, bevorzugt ist jedoch die Herstellung mittels Extrusion oder Coextrusion. The hollow chamber profiles according to the invention are preferably used for producing a frame assembly of a plastic window or a plastic door. By welding mitred pieces of a hollow chamber profile according to the invention, a window or door frame can be obtained. The resulting window or door frame is intended for installation in an opening of a wall of a building or can be installed in the opening of the wall of a building. The hollow chamber profile according to the invention as well as individual parts thereof can also be produced line by line or layer by layer using a line-building or layer-building manufacturing process (eg 3D printing), however preference is given to production by means of extrusion or coextrusion.

B. Sta- bilisatoren, Weichmacher, Pigmente und dergleichen zugesetzt sind. Es ist aus einer Viel- zahl von Hohlkammern 2, 2', 2", 2' " aufgebaut, die jeweils von Innenwänden 3, 3', 3” und teilweise auch von Außenwänden 4, 4', 4", 4" ' des Hohlkammerprofils 1 umgeben sind. Dabei weist das erfindungsgemäße Hohlkammerprofil 1 eine wetterseitige Außenwand 4 und eine raumseitigen Außenwand 4' auf. Bei der zentral im Hohlkammerprofil 1 angeord- neten Hohlkammer 2" handelt es sich um die Haupthohlkammer 2", in der ein Armie- rungselement (nicht dargestellt), vorzugsweise eine Stahlarmierung, aufgenommen werden kann. Die obere Außenwand 4" bildet zusammen mit einem Außenüberschlag 5 einen Falzbereich mit einem Falzgrund 6, der sich bis zu einer Glasleistennut 7 erstreckt. In den Falzbereich kann ein nicht dargestelltes Flächenelement, insbesondere eine Isoliervergla- sung, aufgenommen sein, die durch eine in die Glasleistennut 7 verankerten Glasleiste 8 stabilisiert ist. An der Raumseite ist das erfindungsgemäße Fenster- oder Türprofil 1 über die Haupthohlkammer 2” hinaus in der Darstellung gemäß Fig. 1 nach unten verlängert. Dieser Profilteil wird als Anschlag 9 bezeichnet. Dort ist eine weitere Nut 10 angeordnet, die zur Aufnahme einer Anschlagsdichtung 11 dient, mit der ein aus dem erfindungsgemäßen Hohlkammerprofil 1 gebildeter Fensterflügel im geschlossenen Zustand des Fensters an einem Blendrahmen anliegt. 1 shows an embodiment of the hollow chamber profile 1 according to the invention in the example of a wing profile or sash profile for a plastic window in a cross-sectional view. The hollow chamber profile 1 according to the invention is made of a thermoplastic polymer material, preferably polyvinyl chloride (PVC), especially rigid PVC (PVC-U) or glass fiber reinforced PVC, the further additives such. Stabilizers, plasticizers, pigments and the like are added. It is made up of a multiplicity of hollow chambers 2, 2 ' , 2 " , 2 '" which are each formed by inner walls 3, 3 ' , 3 " and in part also by outer walls 4, 4 ' , 4 " , 4 "'of the Hollow sections 1 are surrounded. In this case, the hollow chamber profile 1 according to the invention has a weather-side outer wall 4 and a room-side outer wall 4 ' . In the central angeord- in the hollow chamber profile 1 Neten hollow chamber 2 "is the main hollow chamber 2", in which an armouring approximately element (not shown), preferably a steel reinforcement can be added. The upper outer wall 4 " forms, together with an outer flashover 5, a folding area with a seaming base 6, which extends as far as a glass bead groove 7. A sheet element, not shown, in particular an insulating glass panel can be inserted into the seaming area. be taken, which is stabilized by an anchored in the glass bead groove 7 glass bead 8. On the room side, the window or door profile 1 according to the invention is extended over the main hollow chamber 2 " out in the illustration of FIG. 1 down. This profile part is referred to as a stop 9. There, a further groove 10 is arranged, which serves to receive an abutment seal 11, with which a formed from the hollow chamber profile 1 according to the invention window sash in the closed state of the window rests against a window frame.
In der in Fig. 1 dargestellten Ausführungsform des erfindungsgemäßen Hohlkammerpro- fils 1 ist die zum Falzgrund 6 gerichtete Wand des Außenüberschlags 5, der Falzgrund 6, die zum Falzgrund 6 gerichtete Wand der Glasleistennut 7 sowie die zum Falzgrund 6 ge- richtete Wand der Glasleiste 8 mit einer niedrigemittierenden Beschichtung 12 versehen. Dazu ist beispielsweise eine dünne Silberschicht auf das Hohlkammerprofil 1 aufgedampft, die mit einem transparenten Lack überzogen ist. Dadurch wird der Wärmedurchgang durch den Glasfalz, auf den ein großer Teil des Wärmedurchgangs durch ein Fenster entfällt, verhindert. Die niedrigemittierende Beschichtung 12 weist vorzugsweise in der Extrusions- richtung des erfindungsgemäßen Hohlkammerprofils 1 eine durchgehende Unterbrechung im Bereich des Falzgrunds 6 auf. Diese Unterbrechung soll Querleitungseffekte verhindern. In the embodiment of the hollow chamber profile 1 according to the invention shown in FIG. 1, the wall of the external flashover 5, the seam base 6, the wall of the glass bead groove 7 directed towards the seam base 6 and the wall of the glass bead 8 directed towards the seam base 6 are provided with a low-emitting coating 12. For this purpose, for example, a thin layer of silver is vapor-deposited on the hollow chamber profile 1, which is coated with a transparent lacquer. As a result, the heat transfer through the glass rebate, which accounts for a large part of the heat transfer through a window, prevented. The low-emissivity coating 12 preferably has a continuous interruption in the area of the rebate base 6 in the extrusion direction of the hollow-chamber profile 1 according to the invention. This interruption should prevent cross-line effects.
Nach außen ist die niedrigemittierende Beschichtung 12 nicht zu erkennen, weil die direkte Sicht darauf in einem Fenster durch die Isolierverglasung verdeckt ist. To the outside, the low-emissivity coating 12 can not be seen, because the direct view of it is hidden in a window by the insulating glazing.
Darüber hinaus ist die der wetterseitigen Außenwand 4 des erfindungsgemäßen Hohlkam- merprofils 1 zugewandte Außenwand des Anschlags 9 ebenfalls mit einer derartigen nied- rigemittierenden Beschichtung 12' versehen. Dadurch wird in einem das erfindungsgemä- ße Hohlkammerprofil 1 enthaltenden Fenster der Wärmedurchgang durch den Zwischen- raum zwischen Flügelrahmen- und Blendrahmen erheblich reduziert. In addition, the outer wall 4 of the stop 9 facing the outer wall 4 of the hollow chamber 1 according to the invention facing the weather is likewise provided with such a low-emissivity coating 12 ' . As a result, in a window containing the hollow chamber profile 1 according to the invention, the heat transfer through the intermediate space between casement frame and frame is considerably reduced.
In alternativen Ausführungsform des erfindungsgemäßen Hohlkammerprofils 1 können die niedrigemittierenden Beschichtungen 12, 12' auch durch eine niedrigemittierende Folie ersetzt sein. Exemplarisch kann dazu Erfindung als niedrigemittierende Folie eine low-e- Kunststofffolie (PET) vom Typ Heat Mirror® HM 55 der Firma Southgate Europe GmbH eingesetzt werden. Die niedrigemittierenden Beschichtungen 12, 12' und/oder die niedrigemittierende Folien können vorzugsweise ein Polymermaterial mit einer Oberflächenspannung von höchstens 20 mN/m umfassen, insbesondere Polytrifluorchlorethylen (PTFCE) und Polytetrafluorethy- len (PTFE). Auf diese Weise werden die mit den niedrigemittierenden Beschichtungen 12, 12' oder mit der niedrigemittierenden Folie versehenen Oberflächen des erfindungsgemä- ßen Hohlkammerprofils 1 schmutzabweisend und sind leicht zu reinigen. In an alternative embodiment of the hollow chamber profile 1 according to the invention, the low-emittance coatings 12, 12 'may also be replaced by a low-emittance film. By way of example, the invention can be used as a low-emitting film, a low-e plastic film (PET) of the type Heat Mirror® HM 55 from Southgate Europe GmbH. The low-emissivity coatings 12, 12 ' and / or the low-emissive films may preferably comprise a polymer material having a surface tension of at most 20 mN / m, in particular polytrifluorochloroethylene (PTFCE) and polytetrafluoroethylene (PTFE). In this way, the surfaces provided with the low-emitting coatings 12, 12 ' or with the low-emitting film of the hollow chamber profile 1 according to the invention become dirt-repellent and are easy to clean.
