    The invention relates to a window or a door for a building with a sash and a frame, wherein the sash frame interconnected sash profiles and the frame have interconnected frame profiles. Further, the invention relates to a method for Fierstellung a window or a door for a building according to the wing frame profiles a sash and frame profiles from a frame is made, the sash profiles and / or the frame profiles are extruded from plastic profiles of a thermoplastic material and in this sash profiles and / or the frame profiles a heat-insulating core is arranged. For windows or doors for closing openings in buildings in addition to metals and wood and plastics for producing the corresponding profiles for the sash or the frame used. Plastics already have relatively good thermal insulation properties. To improve these thermal insulation but additional thermal insulation elements are increasingly placed in the profiles. These may consist of bar material, which are inserted after the production of the plastic profiles in this. On the other hand, it is also known that these additional thermal insulation elements are foamed directly in the profiles, for which purpose a corresponding raw material for producing a plastic foam is introduced into the profiles.
    In addition to thermal insulation plays in such plastic windows and plastic doors but also the rigidity a not insignificant role. Compared to the laminated glass, which are designed at least as Zweiperibenisoliergläser, but often already as three- and Vierscheibenisoliergläser, the profiles used for the sash are made relatively slim. For optical reasons, moreover, the casement profiles are increasingly being reduced in favor of the glass surface, so that relatively narrow profiles must carry a high glass load. In order to avoid the bending of the sash (profiles), stiffening profiles are arranged in the interior of the profiles, which consist for the most part of metal. As a result, however, the thermal insulation value (U value) of the profiles is again deteriorated, since metals are known to be good heat conductors.
    The present invention has for its object to produce or provide a window or door that is easy to produce and that has good static as well as good thermal properties.
    The object of the invention is achieved in the aforementioned window or in the aforementioned door, characterized in that the sash profiles and / or the frame profiles have a core of a thermal insulation, at a melt temperature in the extruder of 200 ° C to a pressure of up to 150 bar, and which is surrounded by a sheath of a thermoplastic material, wherein the sheath is extruded onto the core. Next, the object of the invention is achieved with the aforementioned method, according to which a thermal insulation material is used, which withstands a pressure of up to 150 bar at a melt temperature in the extruder of 200 ° C, and this thermal insulation material fed to the extruder and in this thermoplastic material is extruded onto the thermal insulation material.
    The advantage here is that not only the thermal insulation of the profiles is improved by the highly pressure-resistant thermal insulation material, but that beyond the static properties of the profiles can be improved. It is possible in this way to dispense with additional stiffening profiles made of metal in the plastic profiles, whereby additional steps for the introduction of these stiffening profiles in the sash profiles or frame profiles are avoided. In addition, with the supply of the thermal insulation material to the extruder and the push through the extruder can be omitted on steps for inserting thermal insulation profiles in the finished plastic profiles, which can also reduce the number of necessary steps for the production of windows or doors. In addition, good extrusion between the cladding and the core is achieved by extruding the cladding from the thermoplastic material to the core, which also improves the static properties of the sash profiles or frame profiles.
    According to one embodiment variant of the invention, it is provided that the highly pressure-resistant thermal insulation material is selected or selected from a group comprising XPS, EPS, PUR, PIR, mineral wool, foam glass or mixtures thereof. In particular, with these materials, the above-mentioned effects could not only be achieved but also improved.
    It may further be provided that the core is positively connected to the enclosure. For this purpose, the highly pressure-resistant thermal insulation material can be processed shaping prior to feeding to the extruder. Due to the positive connection of the composite material between the thermoplastic material of the envelope and the highly pressure-resistant thermal insulation material of the core is further improved, whereby the load transfer can be further improved by the sash profiles or the frame profiles.
    For the same reason, it may be alternatively or additionally provided that the core is materially connected to the enclosure. For example, the core can be melted on the surface in the extruder.
    It is also possible that the envelope is a hollow chamber profile with a plurality of hollow chambers, wherein the core is arranged only in one of the plurality of hollow chambers. It is thus possible to provide a profile that has additional empty hollow chambers to accommodate, for example, parts of fittings, etc. This can be dispensed with the subsequent milling or cutting of the core, whereby the introduction of these additional window or door components can be simplified by only the enclosure must be processed accordingly. In addition, it can be achieved that a core profile used for a wide variety of hollow profiles who can, by only one hollow chamber according to the geometry of the core must be formed, but beyond full design variety in the shape of the hollow chamber profiles is available.
    According to another embodiment of the window or the door can be provided that in the joint area of two adjoining sash profiles and / or frame profiles both the adjacent cores and the adjacent cladding are each connected together. Unlike in windows known from the state of the art, in which only the hollow-chamber profiles in the corners are connected to one another, this embodiment can be given better rigidity by the connection of the cores to one another.
    According to a variant embodiment of the method, it can be provided that the highly pressure-resistant thermal insulation material is compacted before being fed to the extruder, whereby a further improvement in the static properties of the window or the door can be achieved.
    Alternatively or additionally, it may be provided that the high-pressure-resistant heat insulation material in the extruder itself is at least partially compressed, as a result of which the number of working steps can be reduced in comparison with the previously mentioned embodiment variant.
    It can also be provided that a high-strength thermal insulation material is used whose melting point is higher by at least 50 ° C than the melting point of the thermoplastic material, whereby the thermal insulation material in the extruder undergoes no change due to the thermal load and thus dimensionally stable, so a optionally downstream of the extruder calibration distance for the at least partially filled with the core plastic profiles can be made easier or the calibration can be done faster.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.
    Each shows in a simplified, schematic representation:
    1 shows a cross section through a window frame profile.
    2 shows a cross section through a sash profile.
    Fig. 3 shows a device for extruding the sheath to the core of the highly pressure-resistant thermal insulation material.
    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.
    In Fig. 1 is a cross section of an embodiment of a frame profile 1 is shown. Next, an embodiment of a sash profile 2 is shown in FIG.
    It should already be mentioned at this point that the profile cross-sections shown have only exemplary character and that in the context of the invention, other profile cross-sections are possible.
    Such frame profiles 1 and sash profiles 2 are used to form a window or door for closing wall openings in buildings.
    As is known per se, a window frame for a lock or a door is produced by connecting a plurality of window frame profiles 1. Also, by connecting a plurality of sash profiles 2, a sash for a fastener or a door is manufactured. The frame is that part of the window or the door on which the sash is in the closed state.
    It is also possible that the window has only a sash, if it is a fixed glazing, so that window is not openable.
    Depending on the geometry of the window, at least three frame profiles 1 or at least three sash profiles 2 are connected to each other at the end faces to the frame or sash. The connection is usually done by welding.
    The window frame profile 1 according to FIG. 1 consists of a core 3 or has a core 3 which is surrounded by an envelope 4. The frame profile 1, in the illustrated embodiment, only a hollow chamber 5, which is completely filled by the core 3, so that therefore the envelope 4 rests directly over the entire circumference according to arrow 6 on the surface of the core 3.
    As is apparent from Fig. 2, but there is also the possibility that a plurality of hollow chambers 5 are formed. In the illustrated embodiment of the casement profile 2, this has five hollow chambers 5. This number of hollow chambers 5 has only exemplary character. It is also possible for fewer or more than five hollow chambers 5 to be formed, for example two, three, four, six, seven, etc.
    Thus, both the frame profile 1 and the sash profile 2 can have one or more hollow chambers 5. In the event that the frame profile 1 and / or the sash profile 2 has more than one hollow chamber 5, the core 3 in only one hollow chamber 5 or a plurality of hollow chambers 5 may be provided with a core 3, in the latter case either all Hollow chambers 5 or more but not all of the hollow chambers 5 are filled with a core 3. For this purpose, it is shown in FIG. 2 that one of the hollow chambers 5 necessarily has a core 3 and, optionally, another core 3 is arranged in another hollow chamber 5 (shown in FIG. 2 with dashed hatching). In each hollow chamber 5 in which a core 3 is arranged, this fills the hollow chamber 5 in its entirety, as has already been described above.
    The casing 4 consists of or comprises a thermoplastic material, for example polypropylene (PP) or a WPC (wood plastic composite). In particular, the sheath is made of polyvinyl chloride (PVC).
    At least on the outside, which is exposed to the weathering, the window frame profile 1 and / or the sash profile 2 in the finished window or the finished door can be provided with an aluminum facing, as is known per se.
    The core 3 consists of a highly pressure-resistant thermal insulation material, in particular selected from a group comprising XPS (extruded polystyrene foam), EPS (expanded polystyrene), PUR (polyurethane foam), PIR (polyisocyanurate foam), mineral wool, foam glass and mixtures thereof , Particularly preferably, the core 3 consists of compacted mineral wool (compacted rock wool).
    The term "highly pressure-resistant thermal insulation material" is understood to mean a thermal insulation material for the core 3, which has a strength at a melt temperature in the extruder of 200 ° C., which is so high that the core 3 withstands a pressure of up to 150 bar. In particular, the core 3 has a long-term compressive strength according to DIN 1606 in the version of the filing date of the present invention of at least 300 kPa, preferably between 300 kPa and 400 kPa.
    Preferably, the recovery time of the thermal insulation material after the pressure load in the extruder is between 2 seconds and 30 seconds, so that a dimensionally accurate calibration can be improved.
    The envelope 4 is extruded onto the core 3, as will be explained in more detail below.
    In the simplest case, the hollow chamber 5, in which the core 3 is arranged, has a square or rectangular cross section. However, the hollow chamber 5 may also have a different cross-section, for example, a partially stepped, as shown in Fig. 1, or a cross-section having a groove, as shown in Fig. 2. This makes it possible that the envelope 4 is not only applied to the core 3 but is connected to this form-fitting manner. For this purpose, the core 3 can be shaped in shaping prior to wrapping with the wrapping 4, for example by cutting or milling at least one, possibly undercut, groove or step. But it is also possible that the respective cross-sectional shape of the core 3 is produced by compression or compression of the thermal insulation material in a shaping tool. In general, the core 3 can already be produced in the desired cross-sectional shape as a rod material or it can be produced from a block or a plate, for example by shaving or milling.
    In Fig. 3 shows a variant of a device 7 for producing the frame profile 1 and / or the wing frame profile 2 is shown. This device comprises an extruder 8, which has a shaping tool 9. In the forming die 9, the cross-sectional shape of the envelope 4, i. determines the cross-sectional shape of the frame profile 1 and the sash profile 2, as is known per se in the production of window profiles or door profiles. It should therefore be made to avoid repetition to the relevant prior art.
    In the extruder 8, a plastic granulate is melted from the thermoplastic material for the envelope or a corresponding mixture of this plastic granules with other additives, such. Dyes, made and melted. The melt is fed to the shaping device 9 and pressed by the latter, as a result of which the window frame profile 1 or the sash profile 2 is formed as a rod product.
    The highly pressure-resistant thermal insulation material for the core 3 is also fed to the forming tool 9 and pushed or pulled by this. In the forming tool 9, the core 3 is encapsulated with the thermoplastic material from which the sheath 4 is produced, so that the core 3 is arranged in at least one hollow chamber 5 (for example Fig. 2) of the sash frame profile 2 or the frame profile 1 to completely fill it.
    The core 3 has, in front of the forming tool 9, at least approximately already the cross-sectional shape which the hollow chamber 5 in which it is arranged has in the finished window frame profile 1 or in the finished sash profile 2.
    If the frame profile 1 or the casement profile 2 are produced as hollow chamber profiles with a plurality of hollow chambers 5 and the highly pressure-resistant thermal insulation material is to be arranged in a plurality of hollow chambers 5, the shaping tool 9 is supplied with a number of separate cores 3 corresponding to the hollow chambers 5 to be filled.
    The device 7 may optionally have a calibration device 10 downstream of the forming tool 9 in the direction of production. In this, the molding tool 9 leaving the frame profile 1 or sash profile 2 is controlled cooled, in particular with water, including the calibration device corresponding coolant connections 11,12. Preferably, the coolant is guided in countercurrent to the conveying direction of the frame profile 1 or sash profile 2. Due to the controlled cooling, the casing 4 shrinks in a controlled manner and thus makes better contact with the core 3, which promotes the formation of bonds.
    According to an embodiment of the window or the door can be provided that alternatively or in addition to a positive connection between the core 3 and the sheath 4 a cohesive connection is formed.
    This can e.g. be achieved in that the heat insulating material of the core 3 is superficially melted, so that this molten area connects to the plastic melt for the envelope. The superficial melting can take place, for example, in the extruder 8 itself, for which purpose a heat insulation material is used for the core which melts superficially at the temperature which the shaping tool 9 has. However, the complete melting of the thermal insulation material is to be avoided. In particular, in this case, a thermal insulation material can be used which has a melting temperature in the
    Range of 90% to 105% of the melting temperature of the thermoplastic material for the enclosure.
    However, it is also possible that the thermal insulation material is already melted before entering the forming tool 9.
    Optionally, it may be advantageous if the heat insulation material for the core 3 is supplied cooled to the forming tool 9 so that it does not completely melt in the forming tool 9.
    According to an alternative embodiment, it can be provided that for the core 3, a high-strength thermal insulation material is used whose melting point is higher by at least 50 ° C, in particular by at least 100 ° C, than the melting point of the thermoplastic material. It is thus the melting of the thermal insulation material in the forming tool 9 avoided. For this embodiment, a mineral wool or rock wool is preferably used for Fierstellung of the core 3. The core can consist entirely of mineral wool or rock wool.
    It is also possible within the scope of the invention to use a multilayer core 3. This consists or in particular comprises an inner core of a first highly pressure-resistant thermal insulation material, which may also have a lower melting temperature. In order to protect this inner core from the influence of temperature in the forming tool 9, the inner core can be encased with a higher melting material which does not melt in the forming tool. In particular, this sheath may consist of mineral wool or rock wool. After the thermal insulation also acts in the direction of the inner core, it is possible to avoid the melting of the core 9 in the forming tool 9 over the short period of time in which a cross-sectional element is located in the area of influence of the shaping tool 9.
    To further improve the compressive strength of the thermal insulation material for the core 3 can be provided that this is compressed. On the one hand, compaction can be carried out before the heat insulation material is fed to the forming
    Tool 9 done. On the other hand, the compression can additionally or alternatively be performed in the forming tool 9 itself. For this purpose, the forming tool 9 in the region of the feed of the thermal insulation material on an opening with a cross-section which is smaller than the cross-section of the thermal insulation material 3, so that it is compressed when pushed through the forming tool 9. This compaction can be combined with a pre-compaction outside of the forming tool 9.
    As already mentioned, from the frame profiles 1, a frame and from the sash profiles 2, a sash for a solid or a door made. For this purpose, the sheaths 4 of the profiles are welded together at the corner regions, which are usually mitred. In addition, the cores 3 in the corner regions can be connected to one another cohesively, for example by these are also welded together or by these are glued together.
    Although no additional stiffening profile made of metal or a WPC must be arranged in the casement or in the frame, of course, if necessary, the possibility of arranging in a Flohlkammer 5 of the profiles, for example, for very large windows or doors, so as to improve the load transfer. Optionally, the at least one stiffening profile can be arranged in the highly pressure-resistant thermal insulation material. It may, for example, be from the high pressure resistant thermal insulation material and the at least one stiffening profile a semi-finished product are produced, which is subsequently supplied to the forming tool 9 and processed as described above.
    For the sake of completeness, it should be noted that the end faces of the frame profile 1 or the sash frame profile 2 have no enclosure 4 as a result of the production.
    It should also be noted that in a window or a door of the frame of the above-described frame profiles 1 or the sash of the above-described sash profiles 2 or both
    Frame can be made of the frame frame profiles 1 described above and the sash made of the sash profiles described above 2.
    The embodiments show or describe possible embodiments of the frame profile 1 and the sash profile 2, wherein it should be noted at this point that also various combinations of the individual variants are possible with each other.
    For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the frame profile 1 or of the sash frame profile 2, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.
