Description

[0001] In a first aspect, the invention relates to a ventilation duct module according to the preamble of claim 1. In a second aspect, the invention relates to a ventilation system according to claim 17. In a third aspect, the invention relates to a building wall according to claim 18.

[0002] Ventilation systems for ventilating buildings are well known. Such ventilation systems can supply and / or exhaust air. The air duct must ensure a connection between a living space on the inside of a building wall and an outdoor area on the outside of a building wall. For this purpose, a wall duct is created through the building wall with a hole or similar cutout. A duct, in particular a feed-through duct, and / or a ventilation unit is integrated within the wall duct. For various reasons, closures (e.g. weather protection hoods or designer interior closures) are installed on the inside and outside of the wall. The closures for the outdoor area are often visibly attached to the building façade. This visibility is frequently undesirable.

[0003] For this reason, air ducts are used that direct the air in such a way that the end cap is not located on the facade, but rather in the side reveal of a wall section. Such reveal ducts protect the visual appearance of the facade. The reveal ducts are integrated into the wall structure. They are often integrated into the wall's thermal insulation.

[0004] In wall structures with an outer layer, especially clinker brick, with or without an air gap, the window frames are often installed butt-jointed with the brick. If a reveal channel is to be installed here, it must be integrated within the outer layer of the wall, especially within the clinker brick.

[0005] The outer layer of the wall, especially the clinker bricks, must be tapered in the area of ​​the reveal channel. Often, installation is not even possible due to the geometry of the reveal channel.

[0006] Such a tapering weakens the outer layer of the wall, especially the clinker brick wall, especially structurally. Weather conditions such as wind loads and showers can cause damage to the outer layer of the wall, especially the clinker brick wall. Tapering of the outer layer of the wall, especially the clinker bricks, should therefore be avoided.

[0007] It is therefore desirable to provide a ventilation duct module and a ventilation system that both meets optical / aesthetic requirements and reduces structural weakening of an outer wall layer, in particular a clinker wall, of a building.

[0008] DE 10 2014 101 544 A1 discloses a complete window module with a ventilation module integrated into an insulating element. The complete window module is installed as a retrofit component in a wall area of ​​the building wall directly adjacent to a window element.

[0009] DE 10 2017 124 111 A1 shows a mounting device for a ventilation device, which has a mounting box to be inserted into an interior wall of the building wall, which is connected via duct sections in a fluid-conducting manner to a facade closure on a window reveal of the building.

[0010] DE 20 2016 100 528 U1 relates to a facade connection device for a ventilation system for supplying and / or discharging air into or out of a building.

[0011] DE 10 2016 103 950 A1 or DE 10 2009 045 668 B3 each concern devices installed in a building wall for ventilating and de-ventilating rooms in a building.

[0012] This is where the invention comes in. Its object is to provide an improved ventilation duct module and ventilation system that at least partially resolves the problems prevalent in the prior art. In particular, it is intended to enable air to be conducted through the building wall in a way that both satisfies visual / aesthetic requirements and reduces structural weakening of the outer wall layer, in particular a brick wall, of a building.

[0013] The object is achieved by the invention with a ventilation duct module of claim 1. The invention is based on a ventilation duct module for a reveal duct, for installation in a building wall with a reveal, comprising a flow duct which connects a reveal connection and a duct connection in an air-guiding direction,

[0014] According to the invention, the ventilation duct module is provided with the reveal connection is arranged on a reveal side facing the reveal within a module outer region which adjoins a module outer side facing an outer side of the building wall, wherein the ventilation duct module has at least one offset region between the reveal connection and the duct connection for guiding an air flow, in which the air guidance direction is offset between two planes, in particular parallel to the building wall and normal to the building wall, from a plane in which the reveal connection lies to a plane in which the duct connection lies.

[0015] By locating the reveal connection on the reveal side within the module's outer area, and offsetting the air flow direction in the ventilation duct module perpendicular to the building wall, a shallow module depth of the ventilation duct module is achieved. This shallow module depth advantageously enables integration of the reveal duct into the building wall, causing only relatively minimal weakening of the wall's outer layer, especially the clinker brick wall. In particular, the wall's outer layer is a clinker brick wall.

[0016] Offsetting the air flow direction normal to the building wall means that the design and arrangement of the flow duct offsets the air flow guided through the ventilation duct module between two planes, in particular planes parallel to the building wall, namely from a plane in which the duct connection is located to a plane in which the reveal connection is located. The air flow direction does not have to run perpendicular to the building wall. In order to offset the air flow direction normal to the building wall, the flow duct is arranged parallel to the reveal side or at a duct angle to the reveal side that is preferably less than or equal to 45°, particularly preferably less than or equal to 40°. The module depth extends perpendicular to the reveal side between the reveal side and an opposite module rear side.

[0017] The smaller the module depth, the greater the beneficial effect of reduced structural weakening of the wall's outer layer, especially the clinker wall. In particular, the wall's outer layer is a clinker wall.

[0018] The ventilation direction describes the flow of air flowing through the ventilation duct module and is located in the middle of the duct cross-section.

[0019] The clinker format, namely the clinker length, the clinker width, and the clinker height, refers in particular to the standard format (NF), in which the clinker length is 240 mm, the clinker width is 115 mm, and the clinker height is 71 mm. The thickness of the mortar layer and thus the distance between two clinker bricks is in particular 10 mm. Nevertheless, other clinker formats and / or mortar layers according to DIN 1053 and / or DIN 105 and / or EN 771 are possible within the scope of the invention. A clinker height includes, in particular, one mortar layer.

[0020] Advantageous further developments of the invention can be found in the dependent claims and specify in detail advantageous possibilities for realizing the concept explained above within the scope of the task and with regard to further advantages.

[0021] According to the invention it is further provided that, the duct connection is arranged within a module interior area which is adjacent to a module interior side which is opposite the module exterior side, wherein the duct connection is arranged on a module rear side opposite the reveal side.

[0022] It is advantageously provided that the ventilation duct module has a module depth which is less than or equal to 120 mm, particularly preferably less than or equal to 110 mm, wherein the module depth extends perpendicular to the reveal side between the reveal side and an opposite module rear side.

[0023] Such a development takes into account the fact that the end of a clinker wall in front of the reveal is usually formed from alternating layers of solid clinker bricks and halved clinker bricks. A width of 120 mm is usually half a clinker length, i.e., half the length of a clinker brick. In a development where the module depth is half a clinker length or less, only the solid clinker bricks need to be tapered and / or notched, and the half clinker bricks can be halved completely along their longitudinal axis to half a clinker width, thereby advantageously reducing the labor required.

[0024] The ventilation duct module, in particular, has a relatively shallow module depth, in particular half the width of a clinker brick, for example, less than or equal to 110 mm. The ventilation duct module, in particular, has a module width composed of a duct connection width, which describes the width of the duct connection, and a module core width. The duct connection width is, in particular, less than or equal to 70 mm and can advantageously be adapted to the width of the reveal duct. The module core width can, in particular, be adapted to the offset of the ventilation guidance direction to be bridged and can, in particular, be 106 mm.

[0025] Advantageously, the outer width of the module's outer area is half, or alternatively, one-third, of the module's width, with the module width extending parallel to the reveal side between the module's outer and inner sides. The smaller the outer width, the closer the reveal connection is located to the module's outer side, thereby advantageously avoiding further weakening of the outer wall layer.

[0026] In particular, it is intended that the interior width of the module interior area is half, or alternatively one third, of the module width.

[0027] Advantageously, the flow channel runs at an angle to the reveal side of less than or equal to 40°. The channel angle is preferably less than or equal to 20°, and particularly preferably less than or equal to 10°. The smaller the channel angle, the smaller the module depth can be, with a comparable offset of the air flow direction.

[0028] Advantageously, the flow channel has a vertically elongated channel cross-section (AKQ), in particular a height-to-width ratio of at least 8 to 1. Due to the slight lateral extension of such a vertically elongated channel cross-section, it is particularly suitable for integration into a reveal surface, which is also vertically elongated. Due to the correspondingly greater height, a flow cross-section is achieved that is necessary for the required air exchange, despite the narrow width of the cross-section.

[0029] Advantageously, the reveal connection has a connection extension extending perpendicular to the reveal side and / or perpendicular to the reveal surface. In particular, the connection extension has a connection length that is less than or equal to 120 mm. In particular, the reveal connection and / or the connection extension is designed to accommodate a cover or similar closing element. In particular, the reveal connection and / or the connection extension has a cover or similar closing element. A connection extension solves, in particular, the problem that, in the prior art, closures for reveal channels are often not suitable for clinker walls because, for example, a window frame and a closure of a reveal channel often do not have the same installation space in the clinker.

[0030] It is advantageous that the connection extension has an outer side wall facing the outside of the building wall, said wall having an outer wall thickness, and an opposite inner side wall having an inner wall thickness, wherein the inner wall thickness is greater than the outer wall thickness. By making the inner wall thickness greater, for example 8 to 25 mm, a connection to a window frame and / or a roller shutter rail can be improved, in particular because an otherwise existing gap is filled by the wall thickness. It is advantageous that the inner side wall of the connection extension and / or the reveal connection is arranged to rest against a window arranged in the reveal or against a roller shutter rail arranged in the reveal, wherein the rest is made directly or via a sealant joint.

[0031] In particular, it is provided that the ventilation duct module and / or the connection extension is formed from at least one of the following materials: plastic, sheet metal, wood fibers. In particular, the ventilation duct module or the module body or the connection extension is formed from a material that meets the fire class of the insulation, i.e., the material used in the insulation layer. In particular, the ventilation duct module or the module body or the connection extension is made from an expanded or extruded plastic.

[0032] Advantageously, at least one bracing element is provided, which is arranged within the flow duct and / or the connection extension. By means of a bracing element designed and / or arranged as aerodynamically efficient as possible, the mechanical stability of the ventilation duct module and / or connection extension can be improved.

[0033] Advantageously, at least one stabilizing sheet is provided for inclusion in a mortar layer of an outer wall layer of the building wall, wherein the outer wall layer is a layer of the building wall facing the outside of the building wall, and the stabilizing sheet is attached to the ventilation duct module or rests against the ventilation duct module, in particular rests on it.

[0034] In particular, it is provided that the ventilation duct module is designed symmetrically to a horizontal plane of reflection (SPE) located in the center of the ventilation duct module. Such a symmetrical design advantageously enables installation on both sides, i.e., left and right or top and bottom in a reveal, without having to modify the design of the ventilation duct module.

[0035] In particular, it is intended that the ventilation duct module, in particular a module body of the ventilation duct module, has a cuboid shape. Due to the cuboid shape and the associated rectangular design of the ventilation duct module, it can be advantageously accommodated in a rectangular recess in the outer layer of the wall. Clinker bricks, in particular, only need to be machined with straight cuts perpendicular to the clinker brick.

[0036] In an advantageous development, the module body has a bevel located between the module outer side and a module rear side opposite the reveal side. In particular, the bevel runs parallel to the air flow direction and / or the flow channel. A bevel can advantageously reduce the volume of the module body, allowing a smaller recess in the wall outer layer, which in turn advantageously reduces the structural weakness of the wall outer layer, in particular the clinker wall.

[0037] In particular, it is provided that the ventilation duct module has a cover, in particular a deflection cover with at least one deflection slat.

[0038] In particular, it is provided that the ventilation duct module has a duct connection section with at least one insulation holder receptacle, wherein the at least one insulation holder receptacle is designed to receive an insulation plug. The insulation holder receptacle has, in particular, a cylindrical shape. In particular, it is provided that the ventilation duct module or the module body is designed and arranged such that an outer wall zone arranged within the outer wall layer parallel to the outer side is not exceeded in the direction of the outer side of the building, wherein the outer wall zone is spaced at least half a clinker width from the outer side to the inside. In such a development, it is advantageously achieved that the outer wall layer, in particular the clinker wall, has at least half a clinker width in the region of the reveal edge zone and thus a minimum mechanical stability.In particular, the outer wall zone is at least 55 mm, preferably 57.5 mm, from the outside of the wall outer layer inwards.

[0039] In a second aspect, the invention also provides a ventilation system comprising a ventilation duct module according to the first aspect of the invention for installation in a building wall, a ventilation unit, and a reveal duct that connects the ventilation duct module and the ventilation unit in an air-conducting manner. The ventilation system advantageously utilizes the advantages of the ventilation duct module according to the first aspect of the invention.

[0040] In a third aspect, the invention also relates to a building wall with a reveal comprising a wall outer layer, in particular a clinker wall, and an insulation layer with a ventilation duct module according to the first aspect of the invention and / or a ventilation system according to the second aspect of the invention, wherein in particular the ventilation duct module is arranged within a reveal edge zone, wherein the reveal edge zone is offset into the building wall parallel to the reveal surface by a zone distance, and in particular is arranged in an insulation layer, wherein the insulation layer lies between the wall outer layer and a wall inner layer.

[0041] The reveal edge zone is defined as the module body not extending beyond the reveal edge zone in a direction from the reveal surface into the building wall, but extending into the reveal interior in the opposite direction. The reveal edge zone thus also encompasses the reveal interior, i.e., a volume enclosed by the reveal. It is advantageous for the ventilation duct module to be housed entirely within the reveal edge zone.

[0042] In a further development, the building wall has an inner wall layer. In particular, the building wall is an outer wall.

[0043] In particular, it is provided that the ventilation duct module has a module height that is a multiple of a clinker height and / or the sum of a clinker height and a mortar layer. In particular, the module height is a multiple of 71 mm or 81 mm. In particular, the module height is between 426 mm and 486 mm. A module height that is a multiple of the clinker height and / or the sum of the clinker height and the mortar layer advantageously enables installation in a clinker wall without having to adjust the height of individual clinker bricks.

[0044] Embodiments of the invention are now described below with reference to the drawing. These are not necessarily intended to represent the embodiments to scale; rather, where useful for explanation, the drawing is schematic and / or slightly distorted. With regard to additions to the teachings immediately apparent from the drawing, reference is made to the relevant prior art. It should be noted that numerous modifications and changes to the form and detail of an embodiment can be made without deviating from the general idea of ​​the invention. The features of the invention disclosed in the description, in the drawing and in the claims can be essential for the further development of the invention, both individually and in any combination.Furthermore, all combinations of at least two of the features disclosed in the description, the drawings and / or the claims fall within the scope of the invention. The general idea of ​​the invention is not limited to the exact form or detail of the preferred embodiments shown and described below, or limited to an object that would be more limited than the object claimed in the claims. For specified dimensioning ranges, values ​​within the stated limits are also intended to be disclosed as limit values ​​and to be used and claimed as desired. For the sake of simplicity, the same reference numerals are used below for identical or similar parts or parts with identical or similar functions.

[0045] Further advantages, features and details of the invention will become apparent from the following description of the preferred embodiments and from the drawing, which shows: Fig. 1 is a partial sectional view of a building wall with a ventilation system, comprising a ventilation duct module according to the invention, Fig. 2 is a sectional view of a further development of the ventilation duct module, Fig. 3 is a perspective sectional view of a ventilation duct module in the installed state, Fig. 4 is a view of a further development of a ventilation duct module, Fig. 5 is a view of a further development of a ventilation duct module with a stabilizing plate, Fig. 6 is a view of a further development of a ventilation duct module with a bevel.

[0046] Fig. 1 shows a partial sectional view of a building wall 210 of a building 300 with a ventilation system 1000, comprising a ventilation duct module 100 according to the invention. The building wall 210 has an outer wall layer 220, which in this case is designed as a clinker wall 222. In further developments, the outer wall layer 220 can also be formed within the framework of a standard thermal insulation composite system or a similar building wall in a different shape than a clinker wall 222. The outer wall layer 220 terminates with an outer side 310 of the building 300. On the side of the outer wall layer 220—opposite the outer side 310—is an insulating layer 230, in which, in particular, insulating material 144 is arranged. In optional further developments, an air layer 226 can be arranged between the outer wall layer 220 and the insulating layer 230. The air layer 226 can have an air layer width 228 of up to 40 mm.The insulation layer 230 is in turn followed by an inner wall layer 240 in the direction of an inner side 320 of the building 300.

[0047] A ventilation unit 200 and a connected duct 142 are arranged in a wall duct 312, which extends through the inner wall layer 240 and partially through the insulation layer 230. Adjoining the duct 142 is a reveal duct 140, which extends parallel to the insulation layer 230 along the outer wall layer 220 in the direction of a reveal 212 to the ventilation duct module 100. The ventilation duct module 100 is arranged within a reveal edge zone LRZ. The ventilation duct module 100 has a duct connection 120 located in the area of ​​the insulation layer 230 and a reveal connection 110 located in the area of ​​the outer wall layer 220. The ventilation duct module 100 can thus shift a ventilation guidance direction LFR from the insulation layer 230 into the outer wall layer 120. The reveal duct 140 is connected to a module body 130 of the ventilation duct module 100 via the duct connection 120.The reveal connection 110 of the ventilation duct module 100 is arranged on a reveal side 137 of the ventilation duct module 100, which is directed toward a reveal surface 214 of the reveal 212. By arranging the reveal connection 110 in the wall outer layer 220, an air flow can be guided into or out of a reveal interior 216 enclosed by the reveal 212 according to the ventilation direction LFR. The module body 130 extends in a direction perpendicular to the building wall 210 from the inside to the outside as far as an outer wall zone WAG, whereby the wall outer layer 220 is not impaired between the boundary of the wall outer zone WAG and the outside 310, and in particular does not need to be recessed.

[0048] The reveal edge zone LRZ extends from the reveal surface 214 parallel to it up to a zone distance ZA into the outer layer. The reveal edge zone LRZ can extend into the reveal interior 216.

[0049] A permeable cover 338 is arranged on the reveal connection 110. In the reveal 212, a roller shutter rail 334 is arranged next to the reveal connection 110 toward the inner side 320, and a window 332 is arranged next to it in the same direction. A sealant joint 336 is arranged between the cover 338 or the reveal connection 110 and the roller shutter rail 334. A sealant joint 336 allows the ventilation duct module to be advantageously installed butt-jointly, increasing its resistance to driving rain.

[0050] In Fig. 2 A further development of a ventilation duct module 100' is shown in a plan view with a horizontal sectional plane, which has a connection extension 112. The connection extension 112 adjoins the reveal connection 110 on the reveal side 137. The reveal connection 110 can be extended via the connection extension 112 so that it extends further towards the reveal surface 214 and / or into the reveal edge zone LRZ and / or into the reveal interior 216. The connection extension 112 has a connection length 118. The connection extension 112 has an outer side wall 114 with an outer wall thickness WSA and an inner side wall 116 with an inner wall thickness WSI. In the present case, the inner wall thickness WSI is greater than the outer wall thickness WSA.The ventilation duct module 100 has a flow duct 128, which is arranged obliquely in the module body 130, namely at a duct angle WK to the reveal side 137, in order to shift the ventilation guidance direction LFR from an insulation layer to an outer wall layer. The flow duct 128 has a duct cross-section AKQ. Optionally, the module body can have a bevel 132—shown here in dashed lines. The bevel 132 can run parallel to the flow duct 128 and / or to the air guidance direction LFR. If the flow duct is not straight, the duct angle is formed in particular from the average of the duct angles of all sections of the flow duct.

[0051] In Fig. 3 The ventilation duct module 100' is shown in a sectional view in the installed state in a building wall 210. The ventilation duct module 100' is connected to a reveal duct 140 via the duct connection 120. Only shortly before reaching the reveal 212, in a reveal edge zone LRZ, is the ventilation guide direction LFR shifted from the insulation layer 230 into the outer wall layer 220 and is guided via the reveal connection 110 and the connection extension 112 to the reveal surface 214. In the present case, the ventilation duct module 100' has a module depth 104 of approximately half a clinker length, and the connection extension 112 has a connection length 118, also approximately half a clinker length. In the present case, the connection extension 112 is arranged directly abutting a window 332.

[0052] Fig. 4 shows a perspective view of a ventilation duct module 100". The module body 130 of the ventilation duct module 100" has a cuboid shape 138 and, in particular, has an approximately rectangular outer shape. A connection extension 112 is connected to the ventilation duct module 100", in particular to the module body 130, at the reveal connection 110. In this case, the connection extension has three struts 160 arranged at a vertical distance across the duct cross-section AKQ. In further developments, it is possible for the module body 130 to have struts alternatively or additionally. The ventilation duct module 100" has a module height 102. The ventilation duct module can be formed from plastic 180, sheet metal 182, or wood fibers 184, whereby a combination of these or other materials is also possible. The ventilation duct module 100" is designed symmetrically with respect to a mirror plane SPE, wherein the mirror plane SPE is arranged horizontally at half the module height 102.

[0053] The ventilation duct module 100" has a module depth 104, which is advantageously relatively small, in particular half a clinker brick width, for example 110 mm. The ventilation duct module 100" has a module width 106. In particular, the module width 106 is composed of an inner area width 156 of a module inner area 152 adjacent to the module inner side 135, which is in particular equal to the width of the duct connection 120, and a module core width 107. The inner area width 156 is in particular less than or equal to 70 mm and can advantageously be adapted to the width of the reveal duct and / or the duct connection 120. The module core width 107 can in particular be adapted to the offset of the ventilation guidance direction to be bridged and can in particular be 126 mm. Within the module core width 107, a module outer area 150 with an outer area width 154 is arranged, adjacent to the module outer side 134.The reveal connection 110 is arranged within the module outer area 150 on the reveal side 137 of the ventilation duct module 100".

[0054] In Fig. 5 A further development of a ventilation duct module 100‴ is shown with a stabilizing plate 170. In the present case, the stabilizing plate 170 is designed as an angled plate and is arranged above the ventilation duct module 100"" in such a way that the horizontal part of the stabilizing plate 170 extends into a mortar layer 224 of the wall outer layer 220 designed as a clinker wall 222. The stabilizing plate 170 can advantageously absorb and / or distribute forces from the wall outer layer and / or achieve mechanical strengthening of the ventilation duct module 100‴. Advantageously, the stabilizing plate 170 is offset from the reveal surface 214 inwards into the wall outer layer 220 and / or covered by a cover 338 so that it is not visible from the outside.

[0055] In Fig. 6 A further development of a ventilation duct module 100"" is shown in the installed state, with a module body 130' having a bevel 132. It is clear that in such a development, the wall outer layer 220, in particular clinker bricks of a clinker wall 222, also only need to be beveled, whereby - especially in contrast to a right-angled notching of the clinker wall - less material needs to be removed from the wall outer layer. In this way, the wall outer layer is advantageously structurally weakened even less.

[0056] In Fig. 7A A further development of a panel 338 in the form of a deflection panel 340 is shown. The deflection panel 340 has a number of deflection blades 342 which are designed to deflect the air flow exiting from a reveal connection 110 and / or a connection extension 112, in particular to direct it away from the building. In particular, the exiting air flow can be deflected away from a window installed in the reveal. Such deflection advantageously prevents an area of ​​the building wall and / or the reveal and / or a component installed in the reveal, such as a window 332 or door, adjacent to the panel from being heated and / or humidified by the escaping air flow. Thus, a deflection panel advantageously prevents long-term visual impairments and / or damage, in particular due to moisture. The deflection panel 340 is designed to be connected to a reveal connection 110 and / or to a connection extension 112.. Fig. 7B shows a cross-sectional view of the deflection panel 340 in a sectional plane SE. In this case, a number of five deflection blades 342 are visible, which are arranged next to one another and, due to their curved cross-section, are designed to change the air flow direction LFR of an air flow exiting a ventilation duct module 100, in particular to direct the air flow away from the building.

[0057] The Figuren 8A, 8B und 8C show a further development of a ventilation duct module 100"" with a duct connection section 122, which adjoins the duct connection 120. The duct connection section 122, which is arranged particularly after the installation of the ventilation duct module 100"" within an insulation layer 230 (not shown), has four insulation holder receptacles 127, two of which are visible. An insulation holder receptacle 127 is designed to receive an insulation holder 124. The essentially shaft-shaped insulation holder 124 has a round, disc-shaped insulation holder head 124.1. The insulation holder receptacle 127 is designed such that, in the installed state of the insulation holder 124, it can accommodate both the insulation holder head 124.1 and an insulation plug 126 flush, as shown in Fig. 8A in the lower insulation holder 127, as well as in Fig. 8C is shown. An insulating plug may be formed from Styrofoam or similar insulating material, in particular from the same material as an insulating material 144 in the insulating layer 230 or from a material that is also used in the duct connection section 122. In Fig. 8B The ventilation duct module 100"" is shown in a sectional view in the pre-assembled state. Visible are an insulation holder 124 and the duct connection section 122 with a first insulation holder receptacle 127A, which faces the insulation holder 124, and an opposite second insulation holder receptacle 127B, which faces an insulation layer 230 (not shown here). In the second insulation holder receptacle 127B, between the duct connection section 122 and the insulation plug 126, an intermediate disk 126.1 is arranged, which serves in particular to better fix the insulation holder 124 in the assembled state. The intermediate disk 126.1 can in particular be made of a harder plastic. In Fig. 8CThe insulation holder is shown in the assembled state. The shaft of the insulation holder 124 penetrates the duct connection section 122, the intermediate disk 126.1 and the insulation plug 126 facing the insulation layer 230 and extends further into the insulation layer 230, in particular into an insulation material 144 not shown here. In particular, the ventilation duct module 100"" can be fastened to an insulation layer 230, in particular to an insulation material 144, by one or more insulation holders 124.
