The present invention relates to an extrusion profile, in particular made of plastic, such as PVC, for a door and / or window system, comprising at least one hollow chamber that extends in the extrusion direction and is delimited by profile walls and an insulating core made of foam which is arranged in the at least one hollow chamber and has a compressive strength of has at least 0.3 N / mm ².

Description

The present invention relates to an extrusion profile, in particular made of plastic, such as PVC, for a door and / or window system, for example of a passive house. The present invention also relates to a method for producing an extrusion profile. Furthermore, the present invention provides a door and / or a window system with an extrusion profile.

Usually, PVC extrusion profiles for windows and / or doors have both steel reinforcement for reasons of statics and to enable fittings to be screwed together as well as an insulation filling made either from PS or EPS in order to achieve a good heat transfer coefficient (U-value). For example, roll-formed steel profiles are used, which on the one hand serve the statics of the window and at the same time serve as a screw base for the fittings. In order to achieve a significantly improved U-value, it is necessary to insert insulation material made of PS or EPS foam into the hollow chambers of the extrusion profile. For example, the insulation materials are pushed into the steel reinforcements in the hollow chambers of the extrusion profiles or completely filled with foam so that the foam forms a firm connection with the extrusion profile. The use of steel profiles is also necessary insofar as they serve as counter bearings for the screw connection in the masonry and the fittings.

DE102008009495A1 discloses such a known PU window frame profile with a hollow chamber and a foam insulating material filling this completely. Additional reinforcement elements in the form of stability-increasing fiber inserts, pipes made of plastic or a fiber composite material or a fitting part are in the insulation material to ensure the necessary mechanical stability of the window frame profile introduced. The reinforcement elements are already placed in the mold when the foam insulation material is foamed and the foam is overmolded. The foam insulation material stiffened with the reinforcement element is then encapsulated in an injection molding process by a rigid polyurethane casing. Disadvantages of the known extrusion profiles are the complex production and the high number of components in order to ensure, on the one hand, sufficient strength or rigidity of the extrusion profiles and, on the other hand, an adequate insulating effect.

The object of the present invention is to improve the disadvantages of the known prior art, in particular to provide an extrusion profile that is simpler and / or which can be produced with fewer components and which in particular has a higher rigidity and / or a better insulating effect.

This object is achieved by the features of the independent claims.

According to this, an extrusion profile for a door and / or window system, in particular for a door and / or window frame, for example a passive house, is provided. The extrusion profile can for example be made of plastic such as PVC. The extrusion profile is produced by an extrusion process that is inexpensive and energy efficient with regard to large production quantities. The extrusion profile is defined by an extrusion direction which defines the longitudinal direction of the extrusion profile, in which the extrusion profile does not essentially change in cross section. The extrusion profiles according to the invention can be used, for example, for door and / or window systems that have a door and / or window profile frame, for example a frame profile of a pivotable or linearly displaceable sliding sash, a frame profile of a stationary so-called fixed sash, a French sash or a post, a profile frame from Door and / or window frames in building wall surrounds, such as a frame profile, or additional frame parts, such as a lining strip profile or a faceplate profile.

The extrusion profile comprises at least one hollow chamber which extends in the extrusion direction and is delimited by profile walls. The extrusion profile preferably has a plurality of hollow chambers which extend in the extrusion direction and are delimited by profile walls. In general, the extrusion profile is largely hollow, can, however, in particular have thin-walled profile walls for delimiting and dividing the interior, which delimit the hollow chambers and / or connect a profile wall forming the outside of the extrusion profile. A hollow chamber does not necessarily have to be completely closed in the circumferential direction, but can, under certain circumstances, be designed to be open by means of slots or larger openings. The at least one hollow chamber is preferably closed in the circumferential direction (around the longitudinal direction). For example, the at least one hollow chamber is open on at least one side, in particular on both sides, in the extrusion or longitudinal direction.

According to the invention, an insulating core made of foam, which has a compressive strength of at least 0.3 N / mm ² , is arranged in the at least one hollow chamber. To determine the compressive strength, the standard test method according to ASTM D1621 can be used, by means of which the compressive properties of hard foams, in particular of hard foam plastic, can be determined and tested. For example, it is the foam is PET, in particular the material Kerdyn ^®, or a foam with similar characteristics, such as the well-known under the trade designation wingo-HT-insulating foam. A major advantage of using a foam insulation core with a minimum compressive strength of 0.3 N / mm ² is that further reinforcement measures, such as the steel reinforcements usually used in the hollow chambers, can be dispensed with. This is accompanied by other significant advantages: reduced weight and thus costs, in particular freight costs, as well as simpler assembly. The foam insulation core can be introduced into the hollow chambers in any desired manner, for example it can be pushed in. In particular the use of a foam according to the invention, in particular of the PET foam as Kerdyn ^® material, or wingo-HT insulation foam for the insulation core has proved to be particularly advantageous for use in generic extrusion profiles for door and / or window systems, for example, in a passive house. In general, the foam according to the invention is a thermoplastic foam material with high mechanical and thermal properties and high resistance to moisture. As a result, the extrusion profile can meet the requirements for statics and strength. Furthermore, the foam according to the invention is characterized in particular the PET foam, preferably the Kerdyn ^® foam material, or the wingo HT insulation foam, are characterized by their high thermal insulation properties and good fire behavior, so that passive houses in particular can achieve a good insulation value. For example, it may be the foam is foamed in particular PET, as the Kerdyn -Schaummaterial ^®, in particular, recycled and / or recyclable plastic material is, for example, in particular foamed PET. Polyethylene terephthalate (abbreviation PET) is a thermoplastic from the polyester family produced by polycondensation. Another advantage lies in the processing of the foam according to the invention, in particular the PET foam material as the Kerdyn ^® -Schaummaterials. This can be cut to size in a simple manner and, for example, can be fastened to one another as desired in the longitudinal direction, for example welded to a buttock, so that essentially no scrap or waste arises. Surprisingly, it has been shown that when arranging a foam insulation core with a minimum compressive strength of 0.3 N / mm ^2, an extrusion profile that is easy to manufacture is created that, on the one hand, has high rigidity and thus statics, and, on the other hand, provides a good insulating effect. With regard to the foam according to the invention, in particular the PET foam material, such as the Kerdyn ^® foam material, or the wingo-HT insulation foam, it has surprisingly been found that the insulating core with the extrusion profile, in particular its inner profile walls and / or one of the outer sides of the Extrusion profile forming profile wall, can be screwed. This means that the foam used in the invention, in particular PE foam material as the Kerdyn ^® material, or the wingo-HT insulation foam, a sufficient resistance against pulling and / or tearing has the screw. It is not necessary to additionally glue the insulation core to the profile walls of the extrusion profile. As a result, the extrusion profile according to the invention can be recycled much more easily. Furthermore, the foam material can be processed with conventional wood processing machines, so that particularly simple shaping is possible without the need for special tools and / or machines.

The wingo-HT insulation foam is generally a high-temperature foam with a bulk density in the range from 100 kg / m ³ to 200 kg / m ³ , in particular in the range from 120 kg / m ³ to 180 kg / m 3 ³ or in the range from 140 kg / m ³ to 160 kg / m ³ . A thermal conductivity according to DIN EN ISO 12667/10456 is less than 0.05 W / (mK), in particular at most 0.041 W / (mK) or 0.035 W / (mK), for example 0.031 W / (mK). Water absorption according to ISO 62 can be less than 5%, in particular less than 4%, 3%, 2% or 1%. Another advantage is the high temperature resistance from -40 ° C to 220 ° C.

In an exemplary development of the profile according to the invention, a, for example, U-shaped or C-shaped stiffening profile, in particular made of metal, such as steel, is arranged in the at least one hollow chamber. The stiffening profile can have a constant cross section in the longitudinal direction and / or be thin-walled. This means that a wall thickness of the reinforcement profile walls can be dimensioned significantly smaller than the outer cross-sectional dimension and / or the longitudinal dimension. For example, the stiffening profile is adapted to the shape of the hollow chamber. The stiffening profile can, for example, rest on 2, 3 or 4 profile walls delimiting the hollow chamber. The stiffening profile can be hollow and thus delimit or form a profile chamber and the insulating core can be arranged in the profile chamber of the stiffening profile. For example, the insulation core and reinforcement profile are preassembled and placed together in the hollow chamber. Alternatively, it is possible to first introduce the stiffening profile into the hollow chamber and then insert the insulating core into the profile chamber of the stiffening profile. In an exemplary embodiment, the insulating core essentially completely occupies the profile chamber, in particular more than 90%, in particular more than 95% or more than 98%. The use of a stiffening profile HT has proven to be particularly advantageous in applications of the extrusion profile in which particularly high demands are placed on the statics and / or the screw strength.

In an exemplary embodiment of the extrusion profile according to the invention, the foam has a minimum compressive strength of 0.5 N / mm ² , 0.75 N / mm ² , 1.0 N / mm ² , 1.25 N / mm ² , 1.5 N / mm ² , 1.75 N / mm ² , 2 N / mm ² , 2.25 N / mm ² , 2.5 N / mm ² , 2.75 N / mm ² or 3 N / mm ² . The compressive strength values are determined using the test method as ASTM D1621.

According to a further exemplary embodiment of the extrusion profile according to the invention, the foam has a thermal conductivity of less than 0.05 W / (mK), in particular of at most 0.041 W / (mK) or 0.035 W / (mK). The thermal conductivity can be determined on the basis of the DIN 12667 standard "Thermal behavior of building materials and building products - Determination of the thermal resistance according to the method with the plate device with the heat flow measuring plate device products with high and medium thermal resistance" and the heat transfer coefficient on the basis of DIN EN ISO 6946 " Components - Thermal resistance and thermal transmittance - Calculation method ". The heat transfer coefficient, also known as the U-value, is a measure of the heat transfer through a solid body of a fluid. With regard to a window and / or a door, it indicates the heat flow, i.e. a thermal energy per unit of time, per area of the door and / or window and per Kelvin temperature difference inside a building and outside the building. The thermal conductivity is generally a material property that determines the heat flow through a material due to the heat conduction. In general, the lower the thermal conductivity, the better its thermal insulation. By means of the foam used, a U-value in a range from 0.7 to 1.3 W / (m ² K) can be achieved for a window and / or a door. Due to the selected materials and properties, the extrusion profile according to the invention has particularly good thermal insulation properties, so that it is particularly suitable for passive houses. In principle, it is conceivable to use foams with a thermal conductivity of less than 0.1 W / (mK).

In a further exemplary embodiment of the present invention, the foam has an axis-parallel screw withdrawal resistance, measured with a thickness of the insulating core of about 20 mm, of at least 100N, in particular of at least 150 N, 200 N or at least 210 N. The screw withdrawal resistance can be based on the standardization EN 320 can be determined. The screw pull-out resistance is generally a measure of the force that is required to pull a defined screw out of the test body, here the foam insulation core. Surprisingly, it has It was found that, contrary to the prejudice that foams cannot be screwed to extrusion profiles, the foam used according to the invention can be screwed sufficiently reliably to the profile walls, in particular made of plastic. Additional gluing or gluing or the like is not necessary. This makes assembly easier and improves recycling.

According to a further exemplary embodiment of the extrusion profile according to the invention, the insulating core is pushed into the hollow chamber in the extrusion direction. The extrusion profile can thus be produced in a simple manner. An extrusion base profile can be produced by extrusion and, in particular, at the same time and / or separately from this, a foam insulating core adapted in this regard can be produced and processed. The foam insulating core can then be introduced, in particular pushed in, into a hollow chamber of the extrusion base profile in the extrusion or longitudinal direction. After the insulating core has been introduced into the hollow chamber in a translatory manner, it can be screwed to the extrusion base profile so that a firm connection is established.

In a further exemplary embodiment of the extrusion profile according to the invention, the insulating core is shaped with respect to the hollow chamber. For example, an external dimensioning of the insulating core can be coordinated with an internal dimensioning of the hollow chamber. For example, there is an undersize between the insulating core and the hollow chamber. Furthermore, an outer dimension of the insulating core can be smaller than an inner dimension of the hollow chamber. As an alternative or in addition, an in particular circumferential gap, viewed with respect to the extrusion direction, in the range from 0 mm to 1.5 mm can be present between an outer dimension of the insulating core and an inner dimension of the hollow chamber. It is possible that the insulating core occupies the hollow chamber to at least 90% and / or at most 100%. At least one spacer cam can be provided on an inside of the profile wall delimiting the hollow chamber facing the insulating core. In this case, the insulating core can come into contact with the spacer cam, so that there is a gap or free space between the insulating core and the profile wall around the spacer cam.

In an exemplary development of the extrusion profile according to the invention, the insulating core and the hollow chamber are matched to one another in such a way that an amplitude of movement of the insulating core in the hollow chamber of a maximum of 3 mm, in particular a maximum of 2 mm or a maximum of 1.5 mm, viewed transversely to the extrusion direction, is permitted . The maximum amplitude of movement ensures that the insulation core does not wobble or wobble in the hollow chamber. It is clear that the edges of the insulating core can be rounded, so that there can be a greater distance between the insulating core and the hollow chamber at the edges themselves. However, the maximum relative movement amplitude between the insulating core and the hollow chamber is still ensured.

According to a further exemplary development of the present invention, in a pre-assembly state there is an oversize of the insulating core with respect to the hollow chamber of up to 1.5 mm and / or of up to 10% of a hollow chamber cross section. For example, the insulating core is pressed axially into the hollow chamber and / or fixed within the hollow chamber by means of pressing. In a further exemplary embodiment of the extrusion profile according to the invention, the insulating core is screwed to at least one profile wall delimiting the hollow chamber. For example, a countersunk screw can be used. For example, the screw is countersunk in the profile wall. For example, the insulating core including the profile wall can be screwed to a building contractor, such as a building wall.

According to an exemplary development, the extrusion profile according to the invention comprises a plurality of hollow chambers, an insulating core being arranged, in particular inserted, in each case in at least two hollow chambers. For example, if particularly high requirements are placed on statics and / or thermal insulation, at least two insulation cores can be used.

In a further exemplary embodiment of the present invention, a mounting profile, such as a widening profile, a faceplate or a lining strip profile, is connected to the extrusion profile or the extrusion base profile. The attachment profile can be produced by extrusion and / or have at least one profile chamber, which extends in the longitudinal direction, in particular the extrusion direction of the attachment profile and / or extrusion profile, and is delimited by attachment profile walls, in which a Insulating core of foam, in particular PET, as Kerdyn ^®, or the well-known under the trade designation wingo-HT insulating foam having a compressive strength of at least 0.3 N / mm ² is arranged. The profile chambers essentially do not change their cross-section and / or their dimensions in the longitudinal direction, in particular the extrusion direction, and are designed to be open on at least one side in relation to the extrusion direction.

According to an exemplary development, the attachment profile and the extrusion profile have a fastening structure for form-fitting and / or force-fitting fastening to one another. For example, the fastening structure can have latching and / or hooking measures. For example, the fastening structure is manufactured in one manufacturing step and / or from one piece with the rest of the extrusion profile or attachment profile, in particular by an injection molding process, in particular made of plastic.

In a further exemplary embodiment of the extrusion profile according to the invention, the hollow chamber and the insulating core are, for example, non-positively, positively and / or cohesively attached to one another. The fastening can be realized, for example, by screwing, pinning or other suitable fastening means, such as clips, sleeves or the like. Cohesive fastenings are also possible. For example, the insulating core can be glued to the hollow chamber, for example by means of wet gluing or dry gluing. An advantage of fastening the hollow chamber and insulating core is that the extrusion profile can be handled more easily. For example, an insulating core of up to 7 m in length can be inserted into the hollow chamber and then fastened. Such an extrusion profile can then be handed over to a window manufacturer or the like, whereby it is ensured that the hollow chamber and insulating core are attached to one another. Another advantage is that the insulation core and hollow chamber can be sawn to size at the same time. Cores with individually cut lengths are no longer necessary. This results in considerable potential for cost savings. Furthermore, the material used for the foam core allows the hollow chamber and the insulating core to be corner welded at the same time. As a result, the corner strength can be increased by welding the insulation core across the surface. Furthermore, the insulation values are improved by a circumferential weld seam Exemplary embodiment, the hollow chamber and the insulating core are attached to one another by a mechanical force input, for example by knurling, in particular from the outside, ie from the hollow chamber, and / or by a thermal input of heat that the hollow chamber and the insulating core as a result of a mechanical force Entry and / or thermal entry of heat resulting deformation of the hollow chamber and insulating core engage in one another, in particular interlock and / or interlock with one another. For example, the hollow chamber can be deformed by the application of mechanical force from the outside in such a way that a fastening nose is formed which extends into the material of the insulating core. Furthermore, it is possible to create a fastening to one another via the perforation structure resulting therefrom by perforating, in particular, punctiformly, in particular from the outside, ie from the hollow chamber, the hollow chamber and at least partially the insulating core. The perforations can then be welded or closed with another filler material, for example a cover or by means of a hollow needle, for example with or without heating the material of the hollow chamber, filled with plastic material.

According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a method for producing an extrusion profile in particular according to the invention is provided. The extrusion profile can for example be made of plastic such as PVC and used for a door and / or a window system, for example a passive house.

In the production method according to the invention, an extrusion base profile with at least one hollow chamber which extends in the extrusion direction and is delimited by profile walls is produced by means of extrusion, in particular plastic extrusion. In the extrusion direction, the cross section of the hollow chamber and / or of the extrusion base profile essentially does not change. Furthermore, the hollow chamber can be designed to be open on at least one side.

According to the invention, an insulating core of foam, in particular PET, for example Kerdyn ^®, or the wingo-HT insulation foam which a Has compressive strength of at least 0.3 N / mm ² , inserted into the hollow chamber in the direction of extrusion, in particular pushed in.

According to an exemplary embodiment of the method according to the invention, the method is set up to produce an extrusion profile which is formed in accordance with one of the previously described aspects and / or exemplary embodiments.

According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a door and / or window system is provided, for example for a passive house. The door and / or window system comprises at least one section-wise a profile frame and / or a profile add-on part of the door and / or the window forming extrusion profile, which is designed according to one of the aspects described above and / or exemplary embodiments and / or produced by a manufacturing method according to the invention is.

In the following description of exemplary embodiments of the present invention, an extrusion profile according to the invention is generally provided with the reference number 1. For the description it can be assumed, for example, that the extrusion profiles 1 are made of plastic, such as PVC, by means of an extrusion process. The extrusion direction E is oriented into the plane of the drawing. The extrusion profiles 1 according to the invention are used in doors or windows, in particular in door or window frames. For example, the extrusion profile 1 can be a frame profile, a sash profile, a widening profile of a sash or a frame, a post profile, a faceplate profile, a casement sash profile, a frame profile, especially for sliding doors or windows, or a lining strip profile.

In the exemplary embodiments of the Figures 1A to 9B the extrusion profiles 1 according to the invention are always shown as part of a door or window system 100. Included is another profile, which can also be produced by extrusion, for example from plastic such as PVC, and interacts with the extrusion profile 1 according to the invention as a component of the door or window system 100, generally provided with the reference number 3.

The extrusion profile 1 according to the invention, as well as the extruded profile 3, has a circumferential wall 5 or 7 which forms a profile outside and defines an essentially constant cross-section or outer shape when viewed in the extrusion direction E. Inside, the extrusion profile 1 and the extruded profile 3 can in particular have thin-walled profile webs or profile walls 9 which, together with another profile wall 9 and / or the outer wall 5, 7, have hollow chambers 10, 11, 13, 15, 17, 19, 21, 47 , 67, 91, 93, 95, 81 limit. A hollow chamber is generally indicated with the reference number 10, and individual hollow chambers can be provided with a further reference number. The profile walls 9 and hollow chambers 10 can be produced in a simple manner by means of the extrusion process.

The extrusion profile 1 according to the invention has an insulating core 20 made of foam, which is arranged in one of the hollow chambers 10, namely in the hollow chamber 21 and has a compressive strength of at least 0.3 N / mm ² . An insulating core is generally indicated with the reference number 20; individual insulating cores can be provided with a further reference number. For example, the insulating core 20 made of PET, such as from Kerdyn ^®, in particular Kerdyn ^® 115, or the wingo-HT-insulating foam. The inventors of the present invention have found that by using a foam insulation core with the predetermined compressive strength of at least 0.3 N / mm ^2, the extrusion profiles 1 according to the invention when used in doors or windows, in particular in passive houses, and the requirements with regard to statics as also ensure with regard to insulation properties. A major advantage is that additional stiffening measures, such as metal stiffeners or fastenings, can be dispensed with.

As in Figure 1A As can be seen, the insulating core 20, 23 is screwed into the extrusion profile 1. For this purpose, a screw 25 is screwed from the outside, for example to a screw 25 attached in the area of a profile wall 27 facing the extruded profile 3, which protrudes into the hollow chamber 23 and into the foam insulating core 23 is screwed. Due to the screwability or screw strength of the foam materials used for the insulating core 20, a screw connection is possible, so that gluing or other material connection between insulating core 23 and profile wall 5 can be dispensed with. This aspect enables simple and environmentally friendly recycling of the extrusion profiles 1. The extrusion profiles 1 according to the invention are produced in a simple manner. First, an extrusion profile base is produced in an extrusion tool and then the insulating core 20 is inserted into a predetermined hollow chamber 10, in particular pushed in in the extrusion direction E. It should be clear that an outer dimension of the insulating core 20 is matched to an inner dimension of the corresponding hollow chamber 10. In this way it is possible to dimension the insulating core 20 exactly with respect to the hollow chamber 10. There is no waste, since the foam material enables sections of any axial length to be produced and to be connected to one another, for example butt-welded to one another, without the need for adhesives.

As in Figure 1A As can be seen, the extrusion profile 1 according to the invention is attached to a building support 29 by means of a screw 27, which may, for example, be a house wall. To the extrusion profile 1, which according to Figure 1A is a stationary door or window system component, an extruded profile 3 is pivotably attached, which forms the movable wing of the door or window system 100. The pivotable connection between the stationary extrusion profile 1 and the extruded profile 3 pivotable for it is implemented by a pivot joint, which is indicated schematically with the reference numeral 31. In the seam area 33 between the extrusion profile and the extruded profile 3, a wing seal 35 is provided for sealing. Furthermore, the extruded profile has a glazing 39 received in a glazing groove 37, such as a glazing rebate.

In Figure 1B is essentially the same door or window system 100 as in FIG Figure 1A shown with the difference that the extruded profile 3 is also designed as an extrusion profile 1 according to the invention. As in Figure 1B As can be seen, an insulating core 20 made of foam with a compressive strength of at least 0.3 N / mm ² , which has an essentially U-shaped cross-sectional shape, is also inserted into the hollow chamber 15. This insulating core 20 is also screwed to the extrusion profile base by means of a screw 41.

the Figures 2A, 2B and 3A, 3B each show analogous door or window systems 100, with variant a consisting of an extrusion profile 1 according to the invention and an extruded profile 3, while variant b consists of two extrusion profiles 1 according to the invention. Correspondingly, the execution in relation to the Figures 1A and 1B to get expelled. As from a comparison of the Fig. 1 , 2 , 3 As can be seen, the extrusion profiles 1 differ essentially with regard to the dimensioning. In Figures 2A and 2B the hollow chamber 21 for the insulating core 23 is dimensioned significantly larger, so that the insulating core 23 itself can also be dimensioned larger in order to fill the hollow chamber 21 as well as possible. In the Figures 3A, 3B the profile wall 3 of the extrusion profile 1 according to the invention transversely to the extrusion direction E is dimensioned larger.

The embodiment of the door and / or window system 100 according to FIGS Figures 4A, 4B is essentially based on the door and / or window system 100 according to FIGS Figures 1A, 1B . In contrast to the embodiment according to Figures 1A, 1B exhibits the door and / or window system 100 according to FIGS Figures 4A, 4B an additional widening profile 43 which is arranged between the building support 29 and the stationary extrusion profile 1 according to the invention. The widening profile 43 is also designed as an extrusion profile according to the invention and has a circumferential profile wall 45 with several profile walls 49 dividing the hollow profile wall 45 into several hollow chambers 47. The widening profile 43 according to the invention is coupled to the extrusion profile 1 according to the invention via a latching or hooking structure 51, wherein latching lugs or latching hooks 53 engage in one another in order to fasten the two profiles 43, 1 to one another. The widening profile 43 according to the invention also has a hollow chamber 55 which is larger than the other hollow chambers 47 and into which a foam insulation core with a compressive strength of at least 0.3 N / mm ^{2 is} inserted, which is screwed again to the profile wall 45 by means of a screw 57 . Furthermore, the hollow chamber 55 and the insulating core arranged therein are positioned with respect to the hollow chamber 21 and the insulating core 23 arranged therein that the fastening screw 27, starting from the profile wall 27 of the extrusion profile 1 according to the invention, extends through the hollow chamber 21 and the insulating core 23 arranged therein as well the hollow chamber 55 and the insulating core 59 arranged therein through to the building support 29 for fastening both the extrusion profile 1 according to the invention, as well as the widening profile 43 according to the invention extends.

In Figure 4B is analogous to too Figure 1B It can be seen that the extruded profile 3 forming the wing is also designed as an inventive extrusion profile 1 with a foam insulating core.
