[0062] Some elements which are common to the described embodiments are first explained below.

[0063] Figure 1A section through a composite profile component 1 for a door, window or facade element (the latter is not shown in full here) is shown. From a plurality of sections of such a composite profile component 1, a frame for a window, door or facade, which is closed on the perimeter (not shown here) or, for example, not closed on three sides, can be produced, wherein the frame has a sash and a leaf frame. The leaf frame is the part of a leaf that is movable relative to the sash on hinge elements (such as swivel and / or tilt hinges or the like), and which surrounds a surface element such as an insulating glass pane 4 on multiple sides, thus on three sides (doors) or four sides (especially windows or facade elements). The term "window" is also used synonymously for doors and facade elements below. The sash is used for installation in a wall opening.

[0064] Figure 1 The composite profile assembly 1 has a frame composite profile 2 and a sash frame composite profile 3. A frame surrounded on three or four sides can be assembled from a plurality of frame composite profiles in the frame composite profile 2, and a sash frame that is usually completely surrounded can be assembled from a plurality of sash frame composite profiles in the sash frame composite profile.

[0065] The composite frame profile 2 has a first metal shell 21 , in particular as an extruded profile made of aluminum, and a second metal shell 22 , in particular as an extruded profile made of aluminum. A frame insulating region 23 is formed between the two metal shells 21 , 22 .

[0066] Preferably, the first and second metal shells 21, 22 of the frame composite profile 2 have at least one cavity 211, 221 respectively. Alternatively, they may have a plurality of cavities.

[0067] The leaf frame composite profile 3 has a first metal shell 31, in particular as an extruded profile made of aluminum, and a second metal shell 32, in particular as an extruded profile made of aluminum. A leaf frame insulating region 33 is formed between the two metal shells 31, 32.

[0068] Preferably, the first and second metal shells 31, 32 of the sash frame composite profile each have at least one cavity 311, 321. Alternatively, they may have a plurality of cavities.

[0069] The composite frame profile 2 is designed for installation in an opening in a wall of a building. The composite frame profile has a connection side 2A which, in the installed state, points toward the wall opening. The composite frame profile also has a slot side 2B in which the composite frame profile points toward the composite sash frame profile 3 or toward the slot space F between the composite frame profile 2 and the composite sash frame profile 3.

[0070] The leaf frame composite profile 3 is designed to receive a surface element, such as an insulating glass pane 4. The leaf frame composite profile here has a glass opening side 3A pointing toward the opening. The leaf frame composite profile also has a opening side 3B, in which the leaf frame composite profile points toward the leaf frame composite profile 3. As shown, the insulating glass pane can be held in the leaf frame or in this case in the leaf frame composite profile 3 by means of sealing strips 34, 35. For this purpose, a glass holding strip 36 can also be provided.

[0071] A notch space or notch gap F is formed between the notch side 2B of the sash composite profile and the notch side 3B of the sash frame composite profile.

[0072] The second metal shell 21 of the frame composite profile 2 and the metal shell 31 of the sash frame composite profile 3 may respectively have a web 222, 312 (here extending in the X direction), with which they partially overlap with the corresponding second metal shell 22 of the sash frame composite profile 2 or the corresponding first metal shell 31 of the frame composite profile 3, respectively, so that the groove space F is laterally covered. In order to close the gap that may be retained between the first metal shell 21 and the web 312 or the second metal shell 32 and the web 222, one or more stop seals 37 may be selectively formed on the web 221 and / or 311.

[0073] The leaf frame composite profile 3 is movable relative to the frame composite profile in direction X and opposite to direction X, so that the corresponding leaf can be opened and closed, for example, by rotation or tilting or parallel erection or the like. The type of movement depends on how the leaf frame and the frame are coupled and on which side of the frame the frame composite profile and the leaf frame composite profile are arranged relative to the hinge element.

[0074] The surface element (preferably a triple-glazed insulating glass pane 4) extends substantially perpendicularly thereto in the Y / Z plane, wherein the direction Z is perpendicular to the Y / Z plane. Figure 1 When calculating the heat transfer coefficient, the 90mm edge of the glass plate is usually calculated together.

[0075] The total insulation area of ​​the frame profile assembly has a sash insulation area 23 and a sash frame insulation area 33, and the sash frame insulation area and the sash frame insulation area complement each other to form a total insulation area, which is basically like a thermal insulation barrier between the two metal shell planes of the sash frame composite profile 2 and the sash frame composite profile 3, and penetrates the composite profile assembly along the Y direction from the first insulation joint 231 through the groove space to the glass edge groove G.

[0076] The overall insulation region has a plurality of (preferably six or more) insulation sections which are arranged between the sides 2A and 3A of the sash composite profile 2 and the sash frame composite profile.

[0077] Furthermore, the insulating glass pane 4 can be held in the sash frame or here the sash frame composite profile 3 by means of seals 34, 35 (or in another way), as shown. The seals 34, 35 can be designed as glass contact seals, which are arranged between the insulating glass pane 4 and the glass holding strip 36 and the second metal shell 32 of the sash frame composite profile. These seals 34, 35 can be made of insulating material or a composite of materials, in particular completely or partially of EPDM.

[0078] The frame insulation area 23 here first has two insulation webs 231, 232 of the frame composite profile 2. These insulation webs are preferably completely or essentially (for example, without thread elements or the like) made of ABS (acrylonitrile-butadiene-styrene copolymer) or polyamide, especially of Polythermid (trademark of the applicant Schüco International KG). If polyamide is used, it is used in foamed form.

[0079] Preferably, the separating web 231 (made of unfoamed plastic) has a lambda value of 0.3 to 0.1, particularly preferably between 0.22 and 0.14, in particular less than 0.16 W / (mK). In particular, ABS with a lambda value of <0.015 W / (mK) can be used.

[0080] If ABS is used, it preferably has a lambda value (Lambda value) of 0.16 W / (mK) or .

[0081] If a foamed plastic, in particular foamed polyamide, is used as the material for the separating webs 231 , 232 , it preferably has a lambda value of 0.3 to 0.1, particularly preferably between 0.29 and 0.10, and in particular less than 0.22 W / (mK) or lower.

[0082] The two separating webs 231 , 232 can also be made, in particular, of different materials from those mentioned above.

[0083] The two isolating webs 231, 232 are arranged in accordance with Figure 1 A first isolation section of the isolation region 23 of the overall isolation region 2 is formed.

[0084] The two isolating webs 231, 232 of the frame composite profile 2 can be configured to be spaced apart from each other. The isolating webs can also be oriented in parallel. These isolating webs 231, 232 can also each have one or more cavities 2311, 2321, here three cavities. In addition, the isolating webs can be of the same length. In addition, the isolating webs can each have a head region 2312 or 2322; 2322, 2323 at their ends, with which the isolating webs are embedded in the corresponding grooves of the first and second metal shells 231, 232, in which the isolating webs can be fixed in a shear-resistant manner, preferably by rolling.

[0085] The space between the two spaced-apart separating webs 231, 232 and the first and second metal shells 21, 22 of the frame composite profile 2 can be completely or substantially (i.e. more than 80%) filled with a foam element, in particular a phenolic resin foam element 233. The foam element can be co-extruded with one of the two separating webs 231, 232, here with the separating web 232 facing the slot side 2B. In this case, a narrow gap, in particular a triangular or wedge-shaped gap in cross section, can remain between the first separating web 221 and the foam element, which gap widens away from the separating web in the slot space F.

[0086] The foam element, in particular the phenolic resin foam element 233, is Figure 1 The second isolation section forming the overall isolation region (see also Fig.13 and Fig.14 ).

[0087] The λ value of the phenolic resin foam element 233 is preferably: λ value = 0.022 W / (mK) or less (see Fig.13 and 14 ).

[0088] The isolating tab 232 facing the slot side 2B has a central sealing barrier block 234 facing the slot side 2B. The central sealing barrier block is preferably made of TPE and / or EPDM. The central sealing barrier block 234 is made of Figure 1 The third insulating section of the total insulating area is formed. The third insulating section can preferably extend from the insulating tab 232 of the frame composite profile in the Y direction over more than half of the width of the slot space F and in the X direction over more than half of the length of the insulating tab 232. The third insulating section can be adhered to the insulating tab 232 or fixed to the bottom element on the insulating tab or co-extruded with the insulating tab.

[0089] Center seal block 234 according to Figure 1 A third isolation section is formed of the overall isolation region.

[0090] In addition to the central sealing barrier 234 (preferably PE foam with a lambda value of ≤0.036 W / (mK)), a central sealing device 235 can be formed in the groove space F, preferably on the separating web 232 of the frame composite profile 2 and preferably also fixedly fixed.

[0091] The stop center seal 235 may have a base body 2351 according to type A and a sealing stop head 2352 on the side facing away from the latching bottom 23511. The base body 2351 is engaged with the latching bottom 23511 of A in the receiving groove 2324 of the separating tab 232, which fixes the latching bottom 23511 on the separating tab 232. The other tab 23512 of A is supported on the second metal shell 22.

[0092] The locking bottom 23511 can be made of TPE. The base 2351 and the sealing stopper head 2352 can be made of EPDM.

[0093] The stop center seal 235 is thus fixed stably to the frame composite profile 2 in the groove space F and nevertheless has good thermal insulation properties. The thermal insulation properties are preferably further improved by the following design.

[0094] According to this advantageous design, which can also be considered as a separate invention, the base body 2351 can be in contact with the central sealing block 234 in the open state of the leaf 3. If the leaf 3 is closed, the base body 235, in particular the sealing stop head 2352, is lifted from the central sealing block 234, because the leaf frame 3 rests against it with the elements of the leaf frame and the base body 2351 is lifted from the central sealing block 234 by a few millimeters, preferably by 1 to 2 mm, when closed. In this case, the gap S1 in the closed state of the leaf frame composite profile 3 is preferably ≥ 0.01 mm and ≤ 2 mm, so that the gap interrupts the direct heat conduction between the elements 234 and 235 at this position.

[0095] Starting from the gap S1, the chamber can be formed at least partially or completely (towards the isolating web 232) in a wedge-shaped manner, for example or preferably between the central sealing barrier block 234 and the base body 2351. Starting from the gap S1, the chamber can also be formed differently, for example rectangularly, in particular as a parallelogram. The gap S1 formed in this way optimizes thermal insulation. When the sash is reopened or the sash frame composite profile 3 is lifted, the sealing stop head 2352 is preferably moved back slightly again due to the elastic effect. The sealing stop head can also rest against the central sealing barrier block 234 if necessary.

[0096] The stop center seal 235 can be made of TPE (especially the bottom) and / or EPDM (foam, especially in the area protruding into the slot).

[0097] The stop center seal 235 can be Figure 1 Another partial section of the third isolation section is formed of the overall isolation region.

[0098] The leaf frame insulating region 33 then preferably has two insulating webs 332 , 333 , which are preferably designed as regions of multi-head webs of a multi-head insulating body 331 , which can be made of a plastic material.

[0099] The multi-end web can preferably have one, two or more cavities 3311, 3312 and here have two separating webs 332, 333, which are preferably oriented completely or essentially parallel to one another (see also Figures 7 to 12 The multi-end link can preferably be made completely or essentially (for example without thread elements or the like) of plastic, in particular ABS such as Polythermid (Schüco) or polyamide. The multi-end link is a plastic hollow body.

[0100] The multi-head insulation body 331 can be formed as a four-head insulation body. The multi-head splice is now a four-head splice. This is particularly advantageous because it achieves good statics of the sash frame composite profile with good thermal insulation.

[0101] The four-head separator 331 has a multi-head tab, which can preferably be made completely or essentially (for example, without wire elements or the like) of Polythermid or polyamide. The two isolating tabs 332, 333 can be formed spaced apart from each other. The isolating tabs can be connected by cross bars 334, 335 in the area of ​​their ends. The two cross bars 334, 335 can be thinner than the isolating tabs 332, 333 of the four-head tab. Thin-walled tabs have better ductility when foaming. In this way, expansion space for possible extension is advantageously created in a simple manner in the multi-head tab during foaming. In addition, a chamber that is thermally insulated relative to the metal shell is created outside the cross bar.

[0102] The two isolating webs 332 and 333 can be designed to be of different lengths. In particular, it can be provided that the isolating web 333 oriented toward the glass slot F is longer than the other isolating web 332 oriented toward the slot space F, in particular more than 10%, preferably more than 20%. This has the advantage that the thermal insulation is further improved near the insulating glass plate 4. The first metal shell 31 can be designed to be correspondingly narrower here. This contributes to an optimized uniform isothermal curve. Further below, with the aid of Figure 2 Explain this in more detail.

[0103] Furthermore, the four-head separator 331 can each have one or more, here two, cavities 3311, 3312. The isolating webs 332, 333 can also each have a head region 3321, 3331 or 3322, 3323 at their ends, with which the isolating webs are respectively engaged in grooves of the first and second metal shells, in which grooves the isolating webs can be fixed in a shear-proof manner, preferably by rolling.

[0104] At least one of the cavities 3311, 3312 can be formed inside the barrier measure 3323. The barrier measure 3323 can be formed on the first isolating strip 332 of the four-head isolating body 331 and extend into the slot space F here. The barrier measure can penetrate the slot space until 50% of the width of the slot space. The barrier measure can contact the stop center seal 235 in the closed state. In addition, the barrier measure can have a cavity 3312. The barrier measure can be foamed by foam or have an insert. The cavity 3311 can also be formed without foaming.

[0105] The barrier measure 3323 can have a limiting wall, which is an element that lifts the sealing stop head 2352 from the central sealing barrier block 234 when closed or in the closed state. Another cavity of the cavity 3322 can be formed between the crossbars 334, 335 and the parallel separating webs 332, 333.

[0106] Cavities 3311 and 3312 may be fully or partially filled with foam as shown.

[0107] The foam can be used as an insulating plastic foam composition ( Figure 1 , Figure 2 , Figure 7 The foam may be formed by foaming the cavities 3311, 3312 (see also for this purpose Figure 8 ). Alternatively, an insert 33111, 33121 made of foam in the form of a tab can be pushed into the cavity 3311, 3312 to this position (see, for example Figure 1 and 3 and 7).

[0108] The inserts 33111 and 33121 may be configured as PU inserts 33111 and 33121. The inserts may exemplarily have a λ value of the following magnitude: λ<0.027 W / (mK).

[0109] The foam may be formed as a PE injection foam. The cavities 3311 and 3312 may have lambda values ​​of the following magnitudes: lambda value of the large cavity 3311 < 0.028 W / (mK); and lambda value of the small cavity 3312 < 0.034 W / (mK).

[0110] The advantageous multi-head insulator 331, especially the four-head insulator, is according to Figure 1 Together with the isolation measure 3323, it forms the fourth and fifth isolation sections of the total isolation area.

[0111] Preferably, the multi-head insulator 331 (made of unfoamed or foamed plastic) has a λ value of 0.1 W / (mK) to 0.3 W / (mK), particularly preferably between 0.14 W / (mK and 0.22 W / (mK), in particular a λ value of <0.16 W / (mK). Unfoamed ABS with a λ value of <0.16 W / (mK) can be used in particular. If, on the other hand, a foamed plastic, in particular a foamed polyamide, is used as the material for the multi-head insulator 331, it preferably has a λ value (Lambda value) of 0.1 to 0.3, particularly preferably between 0.10 and 0.29, in particular as 0.22 W / (mK) or less, and foamed PA (polyamide) with a λ value of <0.21 W / (mK) is particularly preferred.

[0112] It is also conceivable to fill the cavities 3311 and 3312 with foam consisting of an injected foam (PUR) or an insulating material insert (PUR / PE / PF / MF / XPS / PET / EPS) with the stated λ values: the λ value for the large chamber 3311 is <0.028 W / (mK) and the λ value for the small chamber 3312 is <0.034 W / (mK).

[0113] The multi-head insulator 331 can again be produced in particular from Polythermid PT (a brand name of ABS, Schüco International KG). The multi-head insulator can now, for example, have a lambda value of the following magnitude: lambda<0.022 W / (mK).

[0114] The separating webs 332, 333 of the composite sash frame profile can extend parallel to one another or only substantially parallel to one another, so that the distance between the head regions 3321, 3331 or 3322, 3331 on the first metal shell 332 is smaller than the distance between the fixing heads on the second metal shell 333. The angle between the separating webs 332, 333 is less than 30° ( Fig. 9 , Fig.10 ).

[0115] Alternatively, only one of the cavities 3321 , 3322 of the four-head insulator 331 may be provided with foam filling.

[0116] In the glass groove G, a glass groove barrier element 336 may be arranged and / or formed on the four-head insulating body 331 , in particular on the second insulating web 332 thereof.

[0117] This glass groove barrier element 336 can be supplemented by a sealing device if necessary and cross the entire glass groove in a strip shape in the transverse direction (preferably always slightly spaced from the glass edge). The glass groove barrier element can be made of PE or PET.

[0118] Glass notch blocking element 336 according to Figure 1 The sixth insulating section forming the total insulating area can be supplemented with a sealing device if necessary. The glass slot barrier element 336 can be made of a foamed material, in particular foamed PE and particularly preferably XPET.

[0119] For example, it can have a lambda value of: lambda value<0.03 W / (mK), in particular lambda value=0.029 W / (mK).

[0120] Overall, particularly good thermal insulation is produced by the six insulating segments, which may be supplemented by a further sub-segment of the third insulating segment of the design shown and explained.

[0121] The two sealing strips 34, 35 may respectively have a base 341, 351 made of a relatively firm material and a sealing area 342, 352 made of foam such as EPDM. In addition, the two sealing strips may have flag-shaped portions 343, 353, with which the sealing strips can further divide the glass groove into a plurality of chamber-shaped areas, which can selectively optimize the barrier effect as the eighth barrier zone as a whole.

[0122] Overall, a large degree of thermal separation is achieved between the metal shells and overall between the spaces I and II to be separated by the overall separation region.

[0123] Figure 2 This is best illustrated by the diagram Figure 1 Isotherm trends of composite profile components.

[0124] This is calculated according to DIN EN ISO 10077-2 - Thermal performance of windows, doors and closures - Calculation of the heat transfer coefficient - Part 2: Numerical methods for frames.

[0125] The structural depth in the Y direction is 75 mm. However, the structural depth is not limited to this value. In a preferred embodiment, the structural depth can advantageously be between 50 mm and 125 mm.

[0126] exist Figure 2 : The isotherm curve is shown at an external temperature of -10°C (external space I). A temperature of 20°C is assumed in the internal space II.

[0127] In particular, the 0°C isotherm A, the 10°C isotherm B and the 13°C isotherm C can be seen.

[0128] It can be seen that the 0° isotherm A, viewed in the Y direction, always advantageously extends in the lower half of the composite profile assembly (both in the frame composite profile 2 and in the leaf frame composite profile 3). The 0° isotherm A also advantageously always extends in the lower half of the total insulation region, which has the two insulation regions 23, 33, viewed in the Y direction. It also extends in the lower half of the insulating glass 4 (here, for example, a triple glazing with two chambers). The 10° isotherm B, in contrast, always extends in the upper half of the total insulation region and in the upper half of the insulating glass pane 4 or of the two insulation regions 23, 33, and the 13° isotherm C also advantageously always extends completely in the upper half of the total insulation region 23, 33. The isotherms can extend only on the insulating glass 4 itself, at its upper edge (towards the interior).

[0129] In the calculation, a glass edge of 190 mm of an insulating glass pane 4 with three spaced-apart individual glass panes is taken into account. The 0° and 10° isotherms also always extend through the glass pane. The 13° isotherms B and C extend locally at the edge of the insulating glass pane 4. The insulating glass pane 4 can be designed as a triple glazing with a central glass pane and two outer glass panes and a cavity therebetween.

[0130] according to Figure 3 A particularly wide frame is formed. Therefore, the frame composite profile 2 can be designed accordingly.

[0131] The composite profile element 1 can have a width in the X direction of more than 130 mm, in particular more than 150 mm, particularly preferably more than 175 mm.

[0132] The structural depth in the Y direction is again 75 mm. However, the structural depth is not limited to this value. In a preferred embodiment, the structural depth can advantageously be between 50 mm and 100 mm.

[0133] In particular, it is provided here that the frame composite profile 2 is designed to be very wide. For this purpose, it can be provided that the two separating webs 231, 232 each have a phenolic resin foam element 2331, 2332 on two sides facing each other. The phenolic resin foam elements can be extended until they are close to each other, preferably leaving a gap of less than 2 mm.

[0134] This also achieves very good thermal insulation in wide frame composite profiles. Figure 4 The isotherm trend 4 has the same characteristics as described above. Figure 2 The same advantageous features discussed in Figure 3 In the embodiment of the present invention, a foamed part is used in the cavity of the multi-end splice and in Figure 4 An insert is used in , but this achieves essentially equally good results).

[0135] Figure 5 Examples and Figure 1 The difference lies in particular in that the stop center seal 235' is constructed slightly differently. The stop center seal has a slightly different base area. The stop center seal 235' can have one or more cavities 2351 here and also in other embodiments. The cavity 2351 has two sub-chambers here, which are connected by a narrow channel, which also achieves thermal insulation. The stop center seal 235" can preferably be made of TPE and / or EPDM. The entire stop center seal 235' can have one or more cavities 2351. The isolating web 232 turned toward the groove space F also has no cavity here ( Figure 5 , Fig.15 ).

[0136] Figure 6 Examples and Figure 1 The difference lies in particular in that the slightly modified stop center seal 235" also assumes the function of the center seal barrier block 234. As a result, an enlarged and here one-piece center seal 235" is provided, which also abuts against the multi-head insulating body 331 with a shoulder, which forms a sealing device stop head similar to the sealing device stop head 2352 in the closed state of the sash. The stop center seal 235" extends over the entire length of the insulating strip 232 of the sash composite profile on the side of the sash frame composite profile 3 facing the groove space F. The stop center seal can preferably be made of TPE and / or EPDM. The entire stop center seal 235" can have a cavity 2351.

[0137] according to Figure 3 The cavities 3311 and 3321 of the four-head isolator 331 can be foamed. However, alternatively, the inserts 33112 and 33212 made of foamed material can be inserted into the cavities, for example, according to Figure 1 way.

[0138] about Figure 1 The advantages discussed apply in other respects.

[0139] In the combination of the components, according to Figure 1 and 2 Components to achieve U for structural depths ≥75mm (Y direction) f ≤0.95W / (m 2 K) and a width of the profile assembly in the X direction of preferably ≤125 mm, in particular ≤117 mm.
