Description

The invention relates to a profile for a door or wing frame and a window or door wing with a wing frame with an inner shell with such a profile.

State of the art:

The manufacturing industry of metal composite systems (MVS for thermally insulated aluminum profiles) is currently looking for solutions to significantly reduce the energy consumption of buildings. In Germany there is even a regulation stipulating that from 2019 all public buildings should be built as plus energy buildings. Plus energy houses are the continuation of passive houses. Passive houses no longer have heating installed. Plus energy houses even give off energy. Energy is obtained from latent heat (cooking, showering, devices, people, ...) and solar gains (large windows, hot water collectors and photovoltaics), as well as through heat recovery from the air exchange during ventilation and from the wastewater.

Common window concepts can only be improved by increasing the installation depth in their thermal insulation. The industry is currently in the process of increasing the current construction depth from 70mm to 80mm, and there are already the first marketable window systems with a construction depth of 90mm.

Large depths of window profiles are extremely demanding in processing (precise cutting, precise joining). In addition, large depths geometrically lead to problems. Because the pivot point is eccentrically attached to windows, a window sash geometrically requires a certain sash width to be opened. The greater the depth, the greater the minimum radius required. The sash widths are specified in the renovation work, so that the latest generation of windows cannot be installed here.

Conventional metal window sash ( Fig. 1 ) have a casement 209 consisting of an inner shell 211, a mandatory outer shell 213 and multiple glazing 215, which is arranged between the inner and outer shell. The multiple glazing 215 comprises two or three glass panes 217, 219 which are connected to one another at the edge by means of a spacer 221. To reduce the thermal conductivity, the space 223 between the glass panes can have an inert gas filling. This way you can

Manufacture multiple glazing with a thermal conductivity coefficient <0.5 W / m ² K, which are, however, relatively expensive.

This in Figure 1 window shown is a metal window in which the inner and outer shell made of one or more aluminum profiles 225.227, respectively. 229 is formed. Inner shell and outer shell are held together by a glass fiber reinforced plastic seal 231, usually made of polyamide. The polyamide seal 231 is with the aluminum profiles 225.227, respectively. 229 positively and / or non-positively connected, so that a load-bearing composite structure is created. The multiple glazing 215 rests on a glass support 233, which is supported on the inner shell and the outer shell (profile 229). The glass support 233 can be formed, for example, by a local piece of wood.

The sash frame 209 is still the weak point with regard to thermal conductivity, even in modern windows. There are usually cold bridges here, which noticeably increase the overall thermal conductivity coefficient of the window sash. Also sophisticated seals with several separate chambers, as in Fig. 1 air convection and thus heat exchange cannot be prevented. For this reason, the measured u-value of such windows differs depending on the installation position (horizontal or vertical). If the ideal installation position is deviated from, the u-value deteriorates by up to 30 to 50%.

The European patent application EP-A1-2 314 815 shows a window consisting of a window sash and a window frame. The window casement comprises an inner and an outer profile, between which a double glazing is arranged. The inner and outer profile are connected to each other by a seal. The window frame also includes an inner and an outer profile, which are connected to each other via a seal. For the purpose of insulation, an insulating profile is arranged on the inside of the outer profile, which according to a second embodiment can extend with one leg to the inner profile. The insulating profile has a foamed core made of PVC and a coating made of a thermoplastic material such as PVC. The profile mentioned has only an insulating and no static effect and is arranged in the window frame and not in the window casement.

The EP-A1-1 201 868 shows a window with a fixed window and a pivotable window casement. Both frames have inner and outer profiles, which are connected by a seal. According to an exemplary embodiment shown, an elongated channel with an undercut is provided on the inner profile of the window casement. In this channel an extension of a glass support is received, which extends below the multiple glazing. The glass support serves to absorb and remove the weight of the multiple glazing.

The WO 2011/032193 discloses a sash and a stick frame, which are each composed of an inner and an outer profile made of aluminum. The inner and outer profile are connected to a profile bar by means of an insulating part. The insulating part consists of a fine-pored, homogeneous polyurethane plastic with a thermal conductivity in the range of λ <0.024 W / mK, a compressive strength of 140 to 160 Kg / cm ³ and an impact resistance of about 25 mJ / mm2. In order to be able to connect the outer and inner profiles to one another via the insulating parts, these partial profiles have anchoring strips for the absorption of the liquid polyurethane foam.

The DE-OS-10 2008 009 495 discloses a method for producing a profile strip with a foamed insulating core and a covering surrounding the insulating core, in which method first an insulating core is produced in a first molding tool and then extrusion-coated with a rigid coating in a second molding tool. Both the insulation core and the sheathing preferably consist of polyurethane. The profile strip is used to manufacture a window sash and a window frame. In order to prevent the cover from breaking out in the area of the fitting parts when higher tensile or compressive forces are applied, a fiber mat section made of CFRP fabric can be embedded in the cover at these points. The entire profile strip also has a U- or S-shaped rail for reinforcement inside, which is completely embedded in the polyurethane core. This makes it possible to support the load of the glazing on the profile strip.

From the WO 97/22779 is known a window or a door, consisting of a frame, a casement and a glazing inserted into the frame or casement. The frame and casement consist of predefined mass cut to length and joined together at the corners to form the frame or sash profiles. The frame or sash profiles have a core made of a closed-cell rigid foam, for example polystyrene foam, and a shell made of profiles which are connected to the core by means of gluing and pressing together. The polystyrene foam of the core has a bulk density of approx. 45 kg / m3 and a thermal conductivity of 0.03 to 0.035 W / mK. The compressive strength is 0.7 N / mm2.

The Swiss patent CH 552 123 A discloses a wing frame made of aluminum consisting of a room-side support frame and an outer support frame. The supporting frame and the holding frame are connected to each other by means of aluminum brackets. The support frame consists of an aluminum profile with a hollow chamber on which a groove with an undercut is provided on the window side. This groove serves to accommodate the brackets mentioned above. To avoid a cold bridge, the base of the bracket is covered with a plastic.

The EP 1 712 719 A1 discloses a window casement whose inner shell is made from an extruded aluminum profile. A polyamide seal is rolled into two grooves of the aluminum profile. Attached to it is a second seal that bears against the outside of the window and carries a drip rail.

The windows described at the beginning have in common that the glazing is accommodated at the edge between the inner shell and the outer shell. The inner shell can also be formed by a glass retaining strip, which is attached to a profile. In the edge area, however, the flat side of the glazing is not connected to the inner shell.

task

To create a profile for door or casement frames, where the doors or windows have a low u-value with a low installation depth, and the u-value does not change depending on the installation position. It is also an object of the present invention to propose a window sash in which a low u-value can be achieved even with a small installation depth of approximately 80 mm.

description

These and other goals are achieved by the subject matter according to claim 1. Advantageous refinements of the subject matter according to the invention are defined in the subclaims.

The invention relates to a door or a window sash with a sash frame, which consists of an inner shell and an outer shell. A filling, e.g. multiple glazing with two, three or more panes of glass, is arranged between the inner and outer shell. The inner and outer shell are thermally separated from one another by insulation, ie by a region of low thermal conductivity, in order to largely prevent heat exchange between the surroundings and the interior of the building. The insulation, usually in the form of a plastic profile or web, connects the inner to the outer shell. According to the present invention, however, it is also conceivable to dispense with the outer shell. According to the invention, the filling is now connected to the inner shell by a form-fitting and / or material connection, so that the inner shell is additionally stiffened by the filling. The weight is also removed directly through the inner shell. The insulation between the inner and outer shell is due to a foamed, fine-pored plastic body with a λ value of preferably <0.05 W / m K and a compressive strength between 1 and 5 N / mm ² , preferably between 1 and 3 N / mm ² and particularly preferably realized between 1.4 and 2.3 N / mm ² . It is important on the window sash according to the invention that the filling is carried only by the inner shell and not additionally by the outer shell and / or the thermal insulation, as is usually the case with conventional sash frames. In the window according to the invention, the supporting function and insulation function are thus completely separated from one another. The material connection and / or interlocking connection acting between the filling and the inner shell carries the weight of the filling practically completely away from the inner shell. This allows a fine-pored plastic with the above-mentioned physical properties to be used as insulation, because it no longer has an essential supporting function. In contrast to conventional window sashes, where a glass retaining strip is attached to the profile of the inner shell, in the window sash according to the invention the glass retaining strip is integral with the profile of the inner shell. This means that the glass retaining strip is designed so that it can absorb and remove the weight of the glazing.

The integral connection can be realized, for example, by a peripheral, circumferential adhesive point. This can take up a strip of width between 1 and 6 cm, preferably between 2 to 5, and particularly preferably 2.5 to 4 cm on the flat sides of the filling. In addition, a glass support element can be provided. By separating the load-bearing and insulation functions, the insulation only has to support the edge bond or the relatively light outer shell. With an integral window, the insulation only has to be able to support its own weight. On the other hand, the insulation should have such a pressure resistance that it is not compressed when the window sash is put down. Accordingly, an insulation body with low compressive strength and therefore an even better insulation value can be used as the insulation material. The inventors have found that in this case, for example, a foamed fine-pored plastic with a compressive strength between 0.5 and 5 N / mm ² and preferably between 1 and 3 N / mm ² and particularly preferably between 1.4 and 2.3 N / mm ² best meets these requirements. In the window according to the invention, therefore, polyamide seals, which usually have several chambers, are no longer used. By directly attaching the glazing to the inner shell, window sashes or doors with a shallow depth and a low u-value can be produced. So with a thickness of the filling resp. the multiple glazing between 44 and 52 mm a depth of a window sash of less than 90 and preferably less than 85 mm, specifically between 78 and 82 mm can be achieved. This makes the window sash also suitable for renovations.

According to a preferred embodiment, the positive connection is formed by a corner angle profile. The corner angle profile is attached directly to the inner shell. Due to the fact that the corner angle profile lies against the filling on two side edges, the filling is fixed on the inner shell. The corner angle profile can be made from an L-profile. One leg of the L-profile can be fixed to the inner shell by means of screws or gluing or by means of a positive connection. The other leg of the L-profile serves as a stop for the side edges of the filling, with the filling preferably also being jammed.

According to a particularly preferred embodiment, at least two corner angle profiles are arranged in two diagonally opposite corners of the window sash. Such an arrangement of the corner angle profiles achieves a high degree of rigidity of the window sash, so that torsion of the frame is prevented, especially when the panel is additionally blocked. In this case the filling is clamped between the corner angle profiles and the inner shell is stiffened by the filling. The corner angle profile is expediently arranged on the hinge side in the lower corner of the window sash. This allows the main load to be transferred directly to the hinges. In an advantageous embodiment, load-bearing corner angle profiles are provided in all four corners.

The corner angle profile also advantageously serves as mechanical securing of the filling or glazing. For this purpose, an angle can be fastened or molded onto the corner angle profile. The mechanical fuse ensures that the filling, resp. (Multiple) glazing cannot detach from the inner shell. It is also conceivable that that Corner angle profile on the inner surface, on which the filling strikes the corner angle profile, is corrugated.

The corner angle profile is preferably made of fiber-reinforced plastic, in particular of a plastic from the group of polyamides, polycarbonates, polyethers, polystyrenes, polyethylene, polypropylene, polyamide being preferred. The plastic can also include a proportion of recycled material and / or expanded parts. Fiber-reinforced plastic has a low thermal conductivity and can be manufactured with sufficient flexural strength so that such a corner profile can bear the load of the multiple glazing. Because the corner angle profile is advantageously not in contact with the outer shell, this does not result in any noticeable heat exchange.

The bending strength of the corner angle profile is advantageously greater than 2 N / mm2, preferably greater than 4 N / mm2 and particularly preferably greater than 15 N / mm2. The legs of the corner angle profile advantageously have a length of less than 30 cm and preferably less than 20 cm and particularly preferably less than 8 cm. Any gap between the insulation and the multiple glazing - due to the thickness of the corner profile - can be filled with a sealing profile or a plastic foam.

The first leg of the corner angle profile expediently has a width which essentially corresponds to the thickness of the filling.

The insulation body is advantageously an expanded polystyrene particle foam or a foamed PET plastic. These plastics have excellent insulation properties and can be manufactured with the required strength. The plastic can more suitably have a specific weight of <180 kg / m3, preferably <160 kg / m3, and particularly preferably <130 kg / m3, but at least 80 kg / m3 (measured according to the current ISO standard 845 in force ). The λ value of the insulation body is preferably less than 0.08 W / m * K, preferably less than 0.06 W / m * K and particularly preferably less than 0.04 W / m * K.

The inner shell, insulation and an optional outer shell advantageously form a composite structure. For this purpose, the insulation body can be glued and / or rolled or otherwise connected to the inner shell and to the outer shell, if there is one. The insulation body expediently has a thickness of> 15 mm, preferably> 25 mm and particularly preferably> 35 mm.

The inner shell advantageously comprises a profile, in particular a metal, wood or plastic profile. A combination of different materials, such as metal / wood, wood / plastic or metal / plastic, is also conceivable.

A support for the corner angle profile is preferably provided on the profile. As a result, the load of the multiple glazing is introduced directly into the inner shell. It is advantageous at the front of the profile, i.e. facing away from the room, a second groove is provided in which the second leg of the angle profile is received. When assembling the window sash, the corner angle profile can thus be inserted into the profile of the inner shell.

In the case of a metal casement window, a corner connector is preferably arranged in the profile (hollow chamber) of the inner shell adjacent to the first corner angle profile. A hinge can be attached to this to transfer the weight of the window sash directly into the window frame.

A one-piece profile for the inner shell of a door or casement frame has a substantially rectangular hollow chamber which extends over the entire length of the profile. The profile is characterized in that a first groove is provided on the outside of a first hollow chamber wall, the free leg of which runs parallel to the first hollow chamber wall and the groove opening of which is parallel to a second hollow chamber wall adjacent to the first hollow chamber wall. A projection is provided on the outside of the first hollow chamber wall at a distance from the groove opening. In addition, there is a groove on the side of the first hollow chamber wall for receiving insulation. The profile according to the invention has the advantage that narrow casements with excellent insulating properties (heat and sound) can be produced. Because the glass retaining strip (corresponding to the part of the inner profile that is on the side and above the support 35) is integrally formed with the profile, the glazing by means of an adhesive layer on the glass retaining strip, respectively. the leg 37 may be arranged. In the context of the present description, a hollow chamber wall is any wall that forms the hollow chamber space at least in certain areas.

The groove advantageously has undercuts for receiving the insulation. As a result, the insulation is positively and non-detachably connectable to the profile. The insulation can additionally be glued and / or rolled up to the profile. A web parallel to the first hollow wall is expediently provided on the second hollow wall. This web can serve as a fastening web, e.g. for fastening the profile to a wooden frame. In the case of a metal or metal / plastic window, an insertion groove for a seal can be provided at the free end of the web in order to seal the profile against a window or door frame. The web can be an extension of the third chamber wall. A fitting groove can also be provided on the second hollow chamber wall. This is used to hold fittings for opening, closing and swiveling door and window sashes. Further advantageous features can be found in the remaining description.

The insulation body preferably has a lamination made of synthetic resin in some areas. By using an insulation body, preferably a fine-pored plastic that is as stable as possible and has the smallest possible λ-value, an excellent thermal separation of the outer and inner shell can be achieved without the structural principle of the conventional window mentioned at the outset having to be changed significantly. According to the invention, the glass fiber reinforced polyamide seals present in conventional metal windows are replaced by a preferably laminated, fine-pored insulation body. The lamination enables the fine-pored insulation body, which by itself does not have sufficient load-bearing capacity, to be reinforced to such an extent that the composite material produced can completely replace the conventional polyamide seals.

According to an advantageous embodiment, the lamination is provided with a fiber reinforcement. The fiber reinforcement can be through a fiber fabric, mat, nets, aligned roving strands, mostly unidirectional or undirected fiber layers and the like can be formed. This means that the fiber reinforcement can be targeted to the main stress directions to be expected. The majority of the fibers of the fiber reinforcement preferably extend transversely to the longitudinal extension of the profiles.

The lamination is advantageously integrally connected to the insulation body. This results in a stable bond between the insulation body and the fiber reinforcement.

The lamination is expediently provided on at least one side of the insulation body, namely either on that side which faces the filling or faces away from the filling. In many cases, such a lamination on at least one side enables the plastic body to already perform the required supporting function. However, it is conceivable that the lamination on opposite sides of the plastic body, namely on the long sides, which the filling or. Multiple glazing facing and facing away should be provided. The long sides mentioned can thus act as tension and pressure bars. From a production point of view, however, it can also make sense to provide the insulation body with a lamination on all sides or at least on all the long sides.

In order to achieve the required stability, the lamination can extend at least partially onto the inner shell and preferably onto the outer shell. The inner shell and optionally also the outer shell can thus be connected to the insulation body in a force-locking and preferably positive manner.

a third embodiment of the invention.

The one in the Figures 2 to 4 shown frame 9 of a window sash according to the invention has an inner shell 11 and an optional outer shell 13, which are thermally insulated. The inner and outer shell are formed by metal profiles 15, 17, in particular aluminum profiles. The metal profiles 15, 17 are connected to one another by means of thermal insulation. The thermal insulation is formed by an insulation body, in particular a foamed, fine-pored plastic body 19, which is received in grooves 21, 23 of the profiles and is non-detachably connected. The insulation body 19 is preferably rolled into the aluminum profiles, that is to say held in place by undercuts in the grooves 21, 23 and possibly glued (see below description of the Figures 7 to 10 ).

It is now important that - in contrast to conventional windows - the weight of multiple glazing or other fillings is only transferred to the inner shell and preferably to the corner of the frame of the inner shell. For this purpose, according to one exemplary embodiment, a first corner angle profile 25 is provided, which is fastened to the inner shell and / or is supported on the latter. According to the preferred embodiment shown, the corner angle profile 25 with the two legs 24, 26 arranged at right angles to one another is produced from an angle profile 27. The angle section 27 has a first leg 29 in cross section, which as a support or stop for the multiple glazing (in the 2 to 4 not shown) and a second leg 31, which is form-fitting is preferably received in a groove 33 of the profile 15. A projection 35, which is provided at a distance from the free leg 37 of the groove 33, serves as a support for the angle profile leg 29. The distance between the end face 39 of the groove 33 and the projection 35 preferably corresponds to the thickness of the leg 29. A shorter However, leg 37 is conceivable as long as it is ensured that the weight of the multiple glazing is essentially completely diverted to the inner shell 11. The groove advantageously has a depth of at least 10 mm and preferably at least 15 mm. The fact that the corner angle profile 25 extends around the corner of the window sash frame results in a particularly rigid construction.

For reasons of stability, a corner connector 41 is provided adjacent to the corner angle profile 25 and is received in a hollow chamber 43 of the profile 15 ( Fig. 3 ). The corner connector 41 is preferably a stable square profile with strong walls, so that a hinge 50 can be fastened to it by means of appropriate screws, rivets or the like (not shown in the figures) (see FIG. Fig. 4 ).

Below the hollow chamber 43, a fitting groove 44 is provided, which is used to hold conventional fittings. A web 46 adjoins the wall of the profile 15 on the inside of the building, on the free end of which a sealing groove 48 is provided for receiving a plastic seal.

In the Figures 5 and 6 the corner angle profile 25 and the corner connector 41 are shown in more detail. It is important for the corner angle profile 25 that it has the smallest possible thermal conductivity coefficient. It is therefore preferably made of a fiber-reinforced plastic. Glass, carbon, natural, aramid fibers and fibers with similar properties can be considered as reinforcements. The rigidity of the corner angle profile can be increased by appropriate orientation of the fibers in the longitudinal direction of the legs 29, 31 and by the use of rovings. The length of the leg 29 is preferably selected such that there is no contact between the corner angle profile 25 and the outer shell 13. A small air gap of 0.5 to 5 mm, preferably 1 to 2 mm, can also be present between the corner angle profile and the insulation 19. However, there is preferably no gap between the insulation and the side faces of the multiple glazing or filling.

A single corner angle profile 25 is to be provided in at least two corners of a window sash. For example, it can be provided in the two lower corners of a window sash or, according to the preferred embodiment, in two diagonally opposite corners of the window sash. According to the latter variant, a corner profile should preferably be arranged on the hinge side in the lower corner.

The embodiment according to Fig. 7 shows a metal window in section. The multiple glazing consists of triple glazing with an inner glass pane 45, a middle glass pane 47 and an outer glass pane 49, which panes are spaced apart from one another by spacer blocks 51. In order to compensate for size tolerances of the multiple glazing in length, width and installation thickness, compensating elements 53, such as compensating sticks, can be provided (blocking). It can be seen that the multiple glazing is firmly connected to the profile 15 by an adhesive layer 54. The direct gluing with the profile 15 has the advantage that a glass support is no longer absolutely necessary, although one in the Figure 7 is still drawn.

A profile 57 serving as a weather protection profile is inserted into the outer profile 17 in a groove 55. At the upper end of the profile, a seal 59 is provided which seals the outer shell and the outer glass pane 49 against one another.

A window frame 61 serving as a wall connection part, which also has a core 63 made of foamed plastic, serves as a stop for the window sash. The plastic core 63, which is preferably made of the same material as the insulation body 19, is firmly connected to an outer profile 65 and an inner profile 67. A sealing profile 69 arranged on the inside on the outer profile 65 serves to seal a gap 64 present between the insulating body 19 and the plastic core 63. The wall connection part 61 is attached and fastened in the reveal of a window opening (not shown in the figure).

The embodiment according to Figure 8 differs from the window according to Figure 7 in that the window frame 61 and the inner shell are partially made of wood on the room side. The inner shell 11 consists of a wooden profile 70, in which a metal profile 72 is received in a fold 71. The metal profile 72 is firmly connected to the outer shell 13 via the plastic body 19. The metal profile 72, like the profile 15 ( Figure 7 ) a groove 33, which serves to receive the angle profile leg 31. The interaction of groove 33 and projection 35 results in a positive fit with little play for the corner profile 25 used. In this exemplary embodiment, too, the glazing is permanently attached to the outside of the leg 37 by means of an adhesive layer 54.

The variant according to Fig. 10 is characterized in that a window sash is combined with a fixed glazing. Otherwise, the structure is the same as for the window sash from Fig. 7 .

In the Figure 9 a double window sash is shown, the window sash of which can be opened in the same or opposite directions of rotation. On the window sash, which is shown below, a middle cuff 73 is arranged, on which the upper sash strikes. Otherwise, this version corresponds to the one already described, so that it does not need to be discussed in more detail.

According to a second embodiment of the invention ( Figure 11 ) a composite insulation body is provided as insulation, comprising a fine-pored, dimensionally stable and pressure-resistant insulation body made of a material as described above and an optional lamination 74 made of a synthetic resin and an optional fiber reinforcement (in Figure 11 not apparent). In the exemplary embodiment shown, the lamination 74 is provided only on the longitudinal side 75 facing the filling 76 (here: multiple glazing) and on the side 77 facing away from the filling 76. However, it is conceivable that the lamination 74 is provided at least on all long sides of the insulation body 19. Advantageously, but not necessarily, the lamination extends into the grooves 21 of the metal profile 15 and preferably into the grooves 23 of the metal profile 17, where undercuts 79 or. 81 a positive connection is realized. It is conceivable that the insulation body is laminated only on the side surfaces oriented toward the inner profile 15 and the outer profile 57, including the projections. The undercuts 79, 81 are formed by "rolling in", a method in which the plastic material is partially encompassed by deforming aluminum webs.

So that the composite insulation body can also withstand a large transverse tensile force in the longitudinal direction, at least the end face 83 of a first projection 87 connected to the body is firmly glued to the profile 15 of the inner shell 11. Analogously, the end face 89 of a second projection 91 can also be firmly glued to the profile 17 of the outer shell 13. The projections 89, 91 can be made of the same or a different material as the composite insulation body.

Like the window sash according to the invention, the window frame 61 also preferably has a laminated insulation body 93. The insulation body 93 can consist of the same material as the insulation body 19 and is also preferably rolled into the profiles 65, 67 by means of molded projections 103, 105. For this purpose, the profile 67 has grooves 95, the side walls of which form undercuts 97. Likewise, the profile 65 has grooves 99, the side walls of which form undercuts 101. The projections 103, 105 of the insulating body 93 are held in a form-fitting manner in the grooves 95.99.

According to the exemplary embodiment shown, two projections 103 and 105, respectively, are provided on the side walls 107, 109 of the plastic core 93, which are rolled into corresponding grooves 95.99. However, it is also conceivable to provide only one or more than two grooves 95.99. In order to achieve a firm connection also with respect to forces acting in the longitudinal direction of the profiles, the side walls 107, 109 are glued to the inner surfaces of the profiles 65, 67 at least in regions and preferably essentially over the entire area.

As shown in the embodiment shown, the projections 87, 91 respectively. 99,101 made of a different material than the rest of the plastic core 93. In particular, it is conceivable that the projections are formed by a polyamide profile. The polyamide profile can in turn be extrusion-coated with the fine-pored material of the plastic core 93 or in some other way. be connected by positive locking or gluing.

In order to achieve the highest possible u-value, all or at least most of the rebate volume between the window sash and the window frame is preferably filled by a sealing body 111. A special feature of this window construction is that over at least half and preferably over at least 2/3 of the thickness of the plastic body 19

Sealing body 111 on the insulating body 19 and. Plastic core 93 abuts or releases only a minimal gap of less than 3 mm and preferably less than 1 mm. This construction, which is an independent aspect of the invention, largely prevents heat exchange in the space between the casement and the window frame.

The sealing body 111 can be a co-extruded sealing profile with a first section 113 made of a first plastic and a second section 115 made of a second plastic. The second plastic is preferably an elastomer, e.g. based on olefin or urethane, or a thermoplastic polyamide. The second section 115 of the sealing body advantageously has a plurality of chambers 117 arranged one behind the other, which in their area fill the space between the casement and the window frame.

The sealing body 111 is received on the one hand in a sealing groove 119 provided in the profile 67 and on the other hand in a recess 121.

The embodiment according to Fig. 12 differs from that of Fig. 11 essentially in that the plastic bodies 19, 93 are provided on all sides with a lamination 74. It can also be seen that the filling 76 rests on a glass support 123 which is supported on the one hand on the inner shell 15 and on the other hand on the outer shell 17.
