Description

Facade and/or roof with sealing strip with filler

The invention relates to a facade and/or a roof according to the preamble of claim 1.

In facade and skylight constructions, condensate collecting channels have so far been installed primarily on the transom profiles, which drain condensate separately from the seepage water drainage in separate channels or chambers of the post profiles or the sealing systems. The main reason for this is that the inner pane or filling level represents the decisive sealing level, so that the transfer of room air into the pane rebate of the facade is largely prevented. Combining the condensate channel with the seepage water drainage would inevitably lead to warm room air into the rebate, which increases the risk of water vapor diffusion in the case of insulating glass panes into the space between the panes.

Although these designs have proven themselves, there is still a desire to simplify the designs in order to reduce manufacturing costs.

Against this background, the invention is based on the task of developing a cost-effective condensate removal system in which the efficiency and mode of operation are not impaired compared to the prior art. In particular, the air exchange between the interior and the glass rebate of the facade or the skylight should still be prevented. The invention solves this problem through the subject matter of claim 1.

The condensate channel of the transom profile is led directly into the seepage water groove of the post profile and is closed in this area by a filler piece. The filler piece is preferably designed to prevent air exchange and to allow condensate to pass through.

The use of these filler pieces is advantageous for facade and skylight constructions in which the condensate gutters are arranged on the seals for the glass support and in constructions in which the condensate gutters are arranged as a single piece on the facade profiles themselves or via additional profiles.

The filler piece preferably consists of fibers, in particular such that the fibers are arranged lengthwise in the direction of flow in a layered manner or in a chaotic manner or matted. The fibers advantageously consist of glass fiber or plastic, in particular polyamide.

The fine filter structure of the fillers prevents air exchange from the room air to the drainage level. The vapor diffusion through joints in a sealing system is not increased by these fillers and

Registration text dated 29.12.2000 Page

negatively affected. Especially when the capillaries and fiber spaces are filled with liquid, the vapor diffusion in this area is reduced to a minimum or to zero.

According to one variant, at least one of the sealing strips of the transom profiles and/or the post profiles has at least one drainage channel, preferably a condensate channel. The condensate channel is preferably formed integrally onto the sealing strip in a cost-effective and practical manner that does not complicate assembly, so that with this variant of the invention, the assembly of an additional element is not even necessary, although the invention can be usefully supplemented by useful accessories from the further subclaims.

The condensate channel of the sealing strip is preferably constructed at a right angle in a visually appealing and functional manner and is preferably dimensioned according to the subject matter of the further subclaims so that it is in a particularly advantageous relationship with the other sealing strips of the post profiles.

The seals, which are made of elastic material, can be processed using simple tools such as knives and scissors and ensure a high degree of tightness without requiring any special requirements from the processor.

The condensate channel on the sealing strip of the rung visually compensates for the height differences of the seals towards the post.

Further embodiments of the invention can be found in the subclaims.

In the following, embodiments are described in more detail with reference to the drawing. It shows:

In order to understand the invention, various drainage systems are explained below. The invention relates to the variants with a filler piece 25,250.

Fig. 1 shows a part of a facade in metal-glass design with a metal framework made of mullion profiles 1 and transom profiles 2 aligned at an angle to the mullion profile 1.
15

The post profile 1 and the transom profile 2 each have a central web 100 on the front sides, which serves to attach cover shells 101. These cover shells 101 hold infills such as panes, e.g. insulating glass panes 102.

The transom profile 2 is notched at the end in such a way that the profile wall 3 facing the insulating glass pane, which forms the base for the seepage water groove 4 and the sealing groove 5, rests on the sealing groove 6 of the post profile 1 in the assembled state.

The sealing groove 6 of the post profile 1 is located - viewed from the building side of the facade - above a hollow chamber 7. The sealing groove 6 and the hollow chamber 7 together limit the seepage water groove 8 of the post profile 1.

According to the variant shown as an example on the right side of the post profile 1 in Fig. 1, the sealing groove 6 on the post profile 1 can also be open downwards

LOESENBECK · STRACKE · SPECHT · DANTZ - PATENT ATTORNEYS - EUROPEAN PATENT AND TRADEMARK ATTORNEYS

Registration text dated 29.12.2000 Page

be designed so that the sealing groove 6 extends into the area of the hollow chamber 7 and the sealing groove 6 is virtually combined with the hollow chamber 7 to form a sealing groove 9 which combines the functions of the sealing groove and the hollow chamber.

The sealing strip 10 with the actual glass support area 10a and the sealing foot 10b of the locking profile 2 advantageously has a condensate channel 11 which is integrally formed on the glass support area 10a and which preferably has a rectangular shape.

The condensate channel 11 lies tightly against the outer surface of the locking profile 2 with the groove wall facing the sealing body of the sealing strip 10. The groove base 12 is flush with the underside of the profile wall 3. In principle, the condensate channel 11 can also have any other shape, such as a round cross-section, although the rectangular shape is preferred due to its appearance and stability. It is important that the channel cross-section is dimensioned in such a way that sufficient water drainage and sufficient stability can be achieved. The one-piece design of the sealing strip 10 is particularly advantageous. However, multi-piece versions of the sealing strip are theoretically also conceivable.

The sealing strip 10 is guided into the area of the sealing strip 13 of the post profile 1 and there comes into contact with a sealing corner piece 14, to which the glass contact seal 13 of the post profile 1 is also connected or attached.

The sealing corner piece 14 has an extension 15 corresponding to the condensate channel 11 on the sealing strip 10 of the transom profile 2, which encloses the condensate channel 11 laterally and from below and thus supports and aligns it. 30

The sealing corner piece 14 comprises a condensate channel facing the locking profile, which opens into a closed hollow channel in the alignment area of the sealing strip 13, from which a drain 16 is led downwards and passes through the groove base 17 of the sealing groove 6 and opens into the hollow chamber 7. Alternatively, the drain 16 opens into the sealing groove 9 which is open at the bottom. In this case, the drain 16 in the sealing corner piece 14 can also be dispensed with, so that only a drain hole is present in the sealing body of the sealing corner piece 14.

In the facade construction shown in Fig. 1 with the new seal, a structurally simple, cost-effective condensate drainage system is created that works reliably and separately from the seepage water drainage of the seepage water channels 4 and 8.

Fig. 2 shows a facade construction in which the mullion and transom profiles 1, 2 are not changed compared to Fig. 1. In addition to Fig. 1, the sealing strip 21 of the mullion profile 1 here also has a condensate channel 18 formed directly on the glass support area of the sealing strip, which in turn is encompassed and supported by an extension 19 of a sealing corner piece 20.
20

The sealing corner piece 20 comprises a type of foot which engages both in the sealing groove 5 of the transom profile and in the sealing groove 6, 9 of the post profile and is fixed there in a form-fitting manner.

The sealing corner piece 20 further comprises, in alignment with the condensate channel 11, a channel which extends the condensate channel and which passes through the leg of the sealing corner piece which is aligned with the sealing strip 21.

LOESENBECK · STRACKE · SPECHT · DANTZ - PATENT ATTORNEYS - EUROPEAN PATENT AND TRADEMARK ATTORNEYS

Registration text dated 29.12.2000 Page

In this way, the seepage gutter 8 of the post profile is directly connected to the condensate drainage system, i.e. the condensate is drained directly into the seepage drainage system.

The sealing corner piece 20 can have a drainage extension 22 for the seepage water groove 8.

According to Fig. 2, the drainage systems for the condensate and the seepage water are no longer separated but combined into one comprehensive system.

This also makes it possible to reduce the air exchange between the seepage groove 8 and the condensate channel 11,18 to a minimum. For this purpose, a fibrous filter insert (filler) 25 (see below) is inserted into the channel that connects the condensate channels with the seepage channel 8 of the post profile. This filter insert inhibits the air exchange, but on the other hand drains the condensate into the seepage drainage via the adhesion and capillary action of the filter material.

The two different drainage systems of Fig. 1 and 2, i.e. the combined or separate drainage, as well as the arrangement of a condensate channel 18 on the sealing strip 21, can be used and exchanged as desired.

The sealing strip 10 with the condensate channel 11 arranged on it for the transom profile 2 must be arranged at least on the top side of the transom profile on inclined surfaces. If the roof surfaces or facade surfaces are slightly inclined, this seal can also be arranged on both sides of the transom profile. The same applies to facades, where condensate that has formed on the top side of the transom profiles can be covered and drained away by the condensate channel.

The structure and functions of the facade drainage system will be described in more detail below using the following drawing.

Fig. 3 shows the top view of a profile intersection point of post 1 and transom. The sealing strip 21 with the integrated condensate channel 18 is located on post 1. The sealing strips 10, 21 are connected via the sealing corner piece 20. The condensate channels 11, 18 are enclosed and supported by the extensions 15, 19, which also provide the corresponding sealing. In addition, there are correspondingly enlarged adhesive surfaces for connecting the seals to the sealing corner piece.

Fig. 3 shows the separate drainage of the seepage water into the space 9 or the cavity 7 under the sealing strip 21. Here, the drainage channel 23 can also be seen, which leads in extension of the condensate channel 11 into the sealing corner piece 20 to the drain 16.

In contrast to Fig. 3, Fig. 4 again shows a sealing strip or here a glass support seal 13 for the post 1 without a condensate gutter.

Fig. 5 shows a top view of a facade of the type shown in Fig. 2. In this top view of a profile intersection point, the drainage channel can be clearly seen, which is aligned with the condensate channel 11 and opens into the seepage water groove 8 of the post profile 1. This drainage channel is filled with the filter insert (filler) 25, which essentially prevents the exchange of air between the seepage water grooves 8, also called the rebate space, and the condensate channels, also called the interior space. Only the condensate is drained off via adhesion to the fibers and capillary action in channels formed by fibers.

Fig. 6 corresponds largely to the structure according to Fig. 1, only the sealing strip 13 is designed without a condensate channel and the drainage takes place - as

LOESENBECK · STRACKE · SPECHT · DANTZ - PATENT ATTORNEYS - EUROPEAN PATENT AND TRADEMARK ATTORNEYS

Registration text dated 29.12.2000 Page

in Fig. 5 - via the drainage channel 24 and the built-in filter insert (filler) 25.

According to Fig. 7, only the sealing strip 13 is to be inserted into the post 1. The sealing strip 10 with the condensate channel 11 rests against a sealing end piece 26, which extends the transom seal 10 into the area of the post profile 1. The sealing end piece 26 engages with a foot formation in the sealing groove 5 of the transom profile and is fixed there with the seal 10. The width of the sealing end piece 26 corresponds to the total width of the sealing strip 10 including the condensate channel 11, so that on the outside of the sealing end piece

26 the seal 13 can be in sealing contact with the front side under pre-tension. In extension of the condensate groove 11, the seal end piece 26 comprises a drainage channel 27, which can be preceded by a condensate gutter 11. The drainage channel 27 opens into an outlet 16, which in turn leads the condensate into the space 9 or the hollow chamber 7 of the post profile separately from the seepage water.

Fig. 8 shows, like Fig. 7, the intersection point of a post profile 1 with a transom profile 2. Shown is a sealing end piece 28 which is provided in the overlap area between the transom profile and the post and whose drainage channel

27 opens into the drainage channel 8 or into the fold of the post profile. This sealing end piece 26 is particularly suitable for transom profiles that abut at an angle, since the sealing end piece 26 can be cut to match the abutment angle of the profiles.

The sealing end piece 26 has a smooth surface towards the sealing strip 13, to which the glass contact seal 13 can be tightly attached. The drainage channel 27 is - as already shown in Fig. 5 and 6 - equipped with the filter insert (filler piece) 25.

Registration text dated 29.12.2000 Page

Fig. 9 and 10 also reveal in this context that the sealing end piece 26 serves primarily for the crossing points at which the transom profile 2 joins the post profile at an angle. For this purpose, the sealing end piece 26 is designed to be correspondingly longer than is necessary for the right-angled joint in order to be able to be adapted to changed conditions in the simplest way.

Fig. 9 shows the already mentioned oblique joint of the transom profile on the post profile and thus corresponds to the previously described Fig. 7. Only the sealing end piece 26 and the sealing strip 13 are adapted to the joint angle of the profiles.

Fig. 10 shows the top view of an oblique joint between transom and post and otherwise corresponds in the description to Fig. 8. Only the sealing end piece 28 and the sealing strip 13 of the post profile are adapted to the crossing angles.

Fig. 11 shows the structure of a transom post connection of a facade in a perspective and exploded view. The transom profile 2 overlaps the muntin profile 1 in the sealing groove area. The height compensation is achieved by the different heights of the seal 10 and the seal 13, 13.1. This height difference is compensated for by the sealing corner piece 14. A sealing corner piece 14 and a sealing strip that does not have a condensate channel 18 as shown in Fig. 2 are shown. The sealing corner piece 14 can be seen particularly clearly. The sealing corner piece has centering cams 29, 30, 31 on its legs in the joint area with the respective sealing strips 10, 13, which interact with and engage in corresponding hollow chambers of the glass support profiles and thus secure the position of the individual components in relation to one another. The cams also form an enlargement of the contact surfaces for possible gluing of the components to one another.

Either the drainage outlet 16 or the drainage extension 22 with the drainage channel 27 closed by the filler piece 25 can be arranged on the sealing corner piece 14 or alternatively on the sealing corner piece 20.

Fig. 12 also shows a perspective and exploded view of a crossing joint of a transom/post facade. In this figure, the sealing end piece 26 is shown, which also has a centering cam 29 that interacts with a hollow chamber of the glass support profile 10. The glass support profile 13 is supported elastically on the outer surface of the sealing end piece 26. 10

The sealing end piece 26 can be equipped with the drain 16 for separate condensate drainage or, in the case of merging with the seepage water, with the drainage channel 27 and the filter insert (filler piece) 25.

Fig. 13 shows the sealing corner piece 14 as a representative of the sealing corner piece 20, from which the details already described above can be taken. Instead of the drainage channel 27 and the sealing insert 25 shown, the sealing corner piece is to be equipped with the drain 16 for separate condensate drainage.

The same applies to Fig. 14, which shows the sealing end piece 26.

Instead of sealing corner pieces or sealing end pieces, the sealing strip 10 together with the condensate channel 11 can run through to the overlapping area of the transom 2 and the mullion 1 (not shown here). The sealing strip 13 of the mullion profile is then guided under pre-tension to the outside of the condensate groove 11, whereby an adapter part is inserted into the condensate channel 11 in the area of the sealing strip 13, which on the one hand compensates the construction height up to the glass support and closes the condensate channel 11, so that via a hole punched in the

LOESENBECK · STRACKE · SPECHT · DANTZ - PATENT ATTORNEYS - EUROPEAN PATENT AND TRADEMARK ATTORNEYS

Registration text dated 29.12.2000 Page 13

The condensate can be drained from the groove bottom of the condensate channel 11 into the space 9 under the sealing strip 13 or into the chamber 7.

However, the adapter part can also form a channel in which the filler piece 25 is arranged, which causes the drainage into the fold or the seepage water groove 8.

In particular in this last described embodiment, but also in embodiments according to Fig. 7, 8, 9, 10, 12 and 14, which all relate to the sealing end piece 26, the height adjustment between the transom profile and the mullion profile to the glazing support level can also be carried out by means of a two-part mullion seal 13 (see Figure 18). In particular, the combination of an aluminum base strip and a corresponding sealing strip 10 without a condensate channel is intended here.

The structure of the sealing strips, or in particular the sealing strips with a drainage channel attached or molded onto them, will be described in more detail below.

Fig. 15 shows an enlarged cross-section of the sealing strip 10, which rests with its plane X on the two upper edges of the sealing groove 5 and is held in a form-fitting manner in the locking profile 2 by the sealing foot. The sealing body - i.e. the glass support area 10a, which is essentially designed in a known manner and has a sealing foot 10b molded onto it for engagement in the sealing groove 5 - is followed by a web 10c which is molded directly onto the side of the glass support area 10a and which has essentially the height of the glass support area 10a. The condensate channel 11, which is open on one side towards the insulating glass pane but otherwise rectangular and essentially "U-shaped", is formed on the stable web 10c, which overlaps the outer lateral edge of the sealing groove 5. This channel is formed by the groove walls 12, 200 and the groove base 130 and which, with its wall or side facing the locking profile 2, faces the locking profile 2. Page 12

LOESENBECK · STRACKE · SPECHT · DANTZ - PATENT ATTORNEYS - EUROPEAN PATENT AND TRADEMARK ATTORNEYS

on the locking profile 2. The plane Y of the groove wall 12 directed towards the sealing body thus forms the lateral fixing and contact plane on the locking profile 2.

The sealing body or the glass support area 10a has a height "a" - viewed from the plane X, i.e. the upper edge of the sealing groove 5 - while the seepage water groove has the dimension "b" starting from the plane X to the lower edge of the groove base 130. The effective construction height "H" of the sealing strip 13 for the post profile 1 is made up of the height of the glass support area and the dimension "b" of the seepage water groove, i.e. the sum "a+b".

The dimensions a and b are selected such that the groove bottom 130 of the seepage water groove rests on the upper edges of the sealing groove 6 of the post profiles. In this case, the groove wall 200 is also perpendicular to the groove bottom 130 and, in the special design case, forms part of the contact surface for the sealing strip

In an advantageous embodiment, the height "h" of the groove wall 200 is equal to the dimension "b" for the condensate channel 11.

Fig. 16 to 18 allow a comparison of the installation dimensions of the various seals. Fig. 16 shows the sealing strip 10 for the transom profile 2, Fig. 17 shows the sealing strip 13 for the mullion profile and Fig. 18 shows a combined sealing unit 13.1 for the mullion profile. Fig. 16 to 18 are positioned next to each other in such a way that it can be seen that the glass support profile 10 for the transom profiles including the condensate channel 11 has the same height as the mullion seals according to Fig. 16 and 17.

The following therefore applies:

H = a + b.

According to Fig. 18, the sealing strip or the sealing strip 13.1 is constructed in two parts, i.e. it has a sealing strip 21 made of sealing material and a rebate reduction profile 220, which is usually made of the material of the transom profile and mullion profile, e.g. or preferably of aluminum. 5

The fold reduction profile 220 has a height b which, in a particularly advantageous embodiment, corresponds to the groove wall 200 of the seal 10.

In this configuration, the sealing strip 21 can run through to the groove web or base 12 of the sealing strip 10, whereby the sealing foot of the sealing strip 21 is removed in the overlap area with the condensate channel 11. The drainage channel thus created is filled with the filter insert (filler) 25 or closed with a filler. This ensures that the condensate is drained either into the seepage water groove 8 or into the chamber under the sealing strip 7, 9 of the post profile.

Fig. 19 shows a section of the sealing strip 10, into which a sealing molding 230 can be inserted at the end in the area of the condensate channel 11. This sealing molding 230 completes the condensate channel up to the upper sealing surface of the sealing strip 10 and at the same time ends flush with the groove wall 20 on the outside, so that in the overlap area between the transom profile 2 and the post profile 1, the sealing strip of the post profile forms a smooth overall contact surface for the sealing finish. In this case, the sealing strip 10 is led into the overlap area of the profiles without providing additional sealing corner pieces or sealing end pieces.

The sealing molding 230 leaves a channel free so that a punched hole in the bottom of the condensate groove 11 is accessible for draining the condensate.

According to Fig. 20, the sealing mold 240, unlike in Fig. 19, has a continuous channel so that the condensate can be passed through into the seepage water intake of the bar profile. The filter insert (filler) 25 made of synthetic PA filter medium can be inserted into this free channel. 5

Fig. 21 again shows a facade crossing point or area. The sealing strip 10 is again guided into the overlapping area so that the condensate channel 11 rests on the sealing groove of the post profile.
10

The sealing molding 230, 240 forms the closed contact surface in order to bring the sealing strip 13 into sealing contact with the sealing strip 10 or the condensate channel 11.

Fig. 22 ff illustrate that the invention is not limited to the facade construction of Fig. 1. In particular, the invention is also suitable for add-on constructions.

Fig. 22 shows a steel mullion profile 1001 and a steel transom profile 1002. For the purpose of holding and aligning the glass support seals,

The steel post profile 1001 and the steel transom profile 1002 are attached and secured to the attachment profiles 1003, which accommodate the post attachment seal 1004 and the transom attachment seal 1005. The attachment profile 1003 can be made of steel, aluminum, plastic, or even wood.
25

The insulating glass panes 1104 are attached by means of cover profiles 1101 for the post and cover profiles 1102 for the transom as well as brackets 1103.

The post attachment seal 1004 has seepage water grooves 1006, 1007, which are limited by the sealing wall surrounding the screw groove of the attachment profile and the wall of the glass support area.

The post attachment seal 1004 comprises a sealing base 1008, which is placed essentially over the screw channel K of the attachment profile 1003 and extends on the two outer sides of the post profile 1001 facing the insulating glass pane to under the insulating glass panes 1104, where the sealing base is placed to support the glass support areas 1009. The walls 1010 between the respective sealing base 1008 below the insulating glass pane 1104 and the area of the seal 1004 placed over the attachment profile 1003 form the groove base of the seepage water grooves 1006 and 1007.

The glass support areas 1009 are connected to the sealing base 1008 via film hinges 1105 on the longitudinal edges and can therefore be easily separated from it. In the separation plane 1011 between the sealing base 1008 and the glass support area 1009, apart from the edge-side film hinges, there is at most a positive fixation - here in the form of a tongue and groove connection 1106 - in the longitudinal direction of the sealing strand or the sealing strip.

The walls 1010, which form the groove bottom for the seepage water grooves, are located significantly below the parting plane 1011, but at least flush with it. The walls 1010 are connected to one another via further sealing walls that enclose the screw channel.

The latch attachment seal 1005 is also one-piece, but functionally "two-part", with the sealing base 1012 being designed as a sealing strip, which is connected to the glass support area 1013 via at least one longitudinal film hinge. In the parting plane 1011, at most form-fitting means - here in the form of a tongue and groove connection 1106 - are again provided for the

LOESENBECK · STRACKE · SPECHT · DANTZ - PATENT ATTORNEYS - EUROPEAN PATENT AND TRADEMARK ATTORNEYS

Registration text dated 29.12.2000 Page

direction of the base 1012 on the glass support area 1013. There is no further connection between the sealing base 1012 and the glass support area 1013 other than the film hinge 1105.

The glass support or attachment seal 1005 has seepage water grooves 1014, 1015. These are formed by walls 1016 which extend above the parting plane 1011 between the glass support areas 1013 and the area of the seal bridging the screw channel K. The lower plane of the walls 1016 is aligned with the parting plane 1011 and the lower wall of the glass support area 1013.

Furthermore, a condensate channel 1017 is formed on the outside of the glass support areas 1013 of the latch attachment seal - as viewed in the installed position on the latch profile. At least one such condensate channel 1017 is to be provided, preferably two condensate channels 1017 are formed.

According to the embodiment of Fig. 22, the condensate channels 1017 consist of three walls at right angles to one another, the inner wall 1017a being the outer wall of the glass support area, to which a further wall 1017b is perpendicular, the underside of which is aligned with the separating plane 1011, to which an outer wall 1017c is formed, projecting vertically upwards from the wall 1017b.

The wall of the condensate channel 1017b forming the groove bottom is flush with the parting plane 1011, i.e., if a condensate channel 1017 is present, the notch on the post attachment seal 1004 only has to be made over the entire width of the glass support area 1013 including the condensate channel 1017. Both the condensate channel 1017 and the seepage water grooves 1014, 1015 including the glass support areas 1013 thus rest on the seal base 1008 of the post attachment seal 1004.

According to Fig. 1, in this case the condensate channel 1017 as well as the seepage water grooves 1014, 1015 drain together into the seepage water grooves 1006,1007 of the post.

The embodiment of Fig. 23 corresponds essentially to that of Fig. 22. In contrast to Fig. 22, however, the post attachment seal 1019 has a hollow chamber 1018 in the region of the seal base 1020, which can be closed on all sides, but which can also be partially open to the parting plane 1011.

This makes it possible to drain the condensate from the condensate channel 1017 into this hollow chamber 1018. The post attachment seal 1019 is inserted into the floor area of a facade or into the drainage area of a skylight, so that a simplified option for separate drainage of seepage water and condensate can be implemented here. The hollow chamber 1018 is connected to the condensate channel 1017 in a simple manner by piercing the groove base of the condensate channel 1017 in the assembled state.

The positioning of the glass support area 1013 including the at least one condensate channel 1017 is carried out in the simplest manner by notching the glass support area 1009 of the mullion attachment seal 1004, 1019. According to the overlap of the transom attachment seal on the mullion attachment seal, the seal base 1012, 1021 is notched back from the glass support area 1013 accordingly.

Fig. 24 shows a perspective view of a transom-post joint in which the substructure consists of a so-called double-T-beam instead of a hollow profile. Here it can be clearly seen that the condensate channel 1017 is inserted very easily between the correspondingly released post attachment seal 1004, 1019 in the area of the glass support area 1009 and lies tightly against the glass support area 1009.

In particular, because the condensate groove 1017 is aligned with the seepage water groove 1014, 1015 of the transom seal 1005, 1021, only one notch on the post profile is required and the seal is easily ensured. 5

The two drainage systems for the condensate and the seepage water are connected via the condensate channel 1017. To prevent air exchange between the room air and the facade glass rebate, the filler piece 1250 is inserted into the condensate groove in the overlapping area of the transom and mullion as shown in Fig. 25, which closes the opening formed between the condensate channel, the glass pane and the adjacent glass support seal of the mullion profile.

The filler piece 1250 is made of a material that largely prevents the passage of air, but allows any condensate to pass through and drain away into the seepage area of the post profiles.

Figure 26 shows an extruded condensate channel 17 of the type shown in Fig. 25. Here, the transition from the condensate channel to the seepage water drainage or to the fold of the post profile is again made by a sealing adapter 1240, which is inserted into the condensate groove in the overlap area between the transom and the post. This sealing adapter 1240 has a tunnel-like channel 1500, into which a filler piece 25 is inserted, which prevents the passage of air to the fold base of the facade, but on the other hand allows the passage of condensate liquid into the seepage water area of the posts.

The sealing adapter 1240 is preferably made of the same material as the seals themselves in order to ensure sealing against the glass in the area of the condensate passage. The filler piece 1025, like the filler piece 1250 according to Figure 25, prevents air exchange and allows the condensate to pass through.

Figure 25 shows a filler piece 1250, which is adapted in terms of its shape to the condensate guide opening to be closed.

The filler piece 25 according to Fig. 27a consists of fibers 1251 which are joined together and aligned longitudinally parallel in the direction of the condensate channel. Capillary openings are formed between the fibers, which cause liquid transport of the condensate due to the capillary effect and the adhesion effect on the fiber surfaces.
10

Alternatively, hollow fibers 1252 may form the body of the filler, with capillaries being provided both by the interfiber spaces and by the hollow fibers.

Figure 27b shows a filler piece 1025 which consists of chaotically arranged fibers, the individual fibers of which are interwoven or matted. Here too, the condensate is transported into the common drainage plane by adhesion to the fibers and also by capillary action. The fibers can preferably consist of glass fibers, polyamide fibers or similar.

The use of these filler pieces is suitable for all facade designs in which condensate is collected together with the seepage water.

In the event that the filler piece 25,1025 does not have sufficient elasticity to be adapted to the sealing pressures of the glass support seal, it is provided to arrange a sealing support or a sealing strip 1253 on the side of the filler piece facing the glass pane.
