Description

The present invention relates to thermal insulation for a building wall in the basement area of a house with insulation that is arranged on the building wall. Furthermore, the present invention relates to a method for installing a light well on a building wall provided with thermal insulation, and a method for producing a prefabricated insulation.

Thermal insulation for buildings is becoming increasingly important these days. It is also particularly desirable to insulate the basement area of a house. In the past, however, the arrangement of a light shaft, which was arranged in the area of openings, for example windows, in the building wall in the basement area, proved to be very expensive. In some cases, holes were pre-drilled in the building wall, to which the light shaft was then to be attached. However, once the thermal insulation had been installed, it was extremely difficult to locate these pre-drilled holes. Another solution, according to the utility model specification DE 203 03 405 U1 , suggests that the insulation in the area of the light well should be provided in multiple pieces and pieced together around the light well. This form of insulation is also extremely complex. Furthermore, the fastenings represent thermal bridges and subsequent plastering is very time-consuming.

The applicant has therefore in the Patent EP 2 226 448 B1 proposed a solution in which an insulating board, which is provided on the outside with a lining in the form of a fiber cement board, is placed on the building wall, the insulating board having attachment points for a light shaft. However, such an insulating board requires an additional on-site seal. In addition, such a lamination is comparatively heavy and thick and therefore makes installation on the construction site more difficult. Finally, fiber cement boards have to be cut according to the shape of the insulation board, which means that insulation consisting of the insulation board and the lining cannot be used flexibly in terms of size. After all, cutting is laborious and error-prone

It was therefore the object of the present invention to provide thermal insulation and a method for installing a light well on a building wall provided with thermal insulation which does not have the disadvantages of the prior art.

The problem is solved with thermal insulation for a building wall in the basement area of a house, with a prefabricated insulation that is arranged on the building wall, the insulation having attachment points to which a light well can be attached, the insulation consisting of an insulation board and a lamination , where the liner is a polyurea coating.

The present invention relates to thermal insulation for a building wall in the basement area of a house with insulation that is arranged on the building wall. The insulation is preferably glued to the building wall, but can also be fastened to the basement wall in a positive and/or non-positive manner, for example with screws. The building wall can be either a concrete wall or masonry, for example made of sand-lime brick, aerated concrete and/or bricks.

The insulation is what is known as perimeter insulation. Perimeter insulation refers to the thermal insulation of building components and structures in contact with the ground on the outside. This can be both the insulation below the floor slab of a building and the wall insulation of a cellar wall embedded in the ground. The insulation must be water and pressure resistant, so preferably closed cell foam materials are used.

The insulation has attachment points to which a light well can be attached. The light well is therefore only attached to the insulation and not to the building wall itself. It can therefore initially the insulation on the Arranged building wall, especially glued, and then the light shaft are mounted on the insulation without having to be drilled into the building wall. This considerably simplifies the installation of the light well on an insulated, ie thermally insulated, basement wall. The attachment points are preferably markings on the lamination. This advantageously allows for a simpler and error-free installation of a light well without the insulation being structurally impaired or damaged. Alternatively or additionally, at least some attachment points are bores or pilot bores.

The person skilled in the art understands that in principle it is also possible to mount a light shaft entirely or partially outside the fastening points. The attachment points merely show the user optimum attachment locations, in particular for the applicant's light wells.

According to the invention, the insulation now consists of an insulation board and a lining, the lining being a polyurea coating. In particular, the insulation board according to the invention is an assembly insulation board. Such a coating can advantageously be applied in a particularly simple manner by means of a spraying process and is permissible both outdoors and on the ground, is UV-resistant, weather-resistant and chemical-resistant, highly pressure-resistant and watertight and lightfast. It is particularly advantageous that the coating can be flexibly applied to all desired shapes of the insulation board without any problems and can cover it over the entire surface, so that the insulation is also secure from behind, at least if necessary with a seal, in particular on the side, and/or a full-surface connection, in particular Bonding to the building wall. This is a considerable advantage, particularly in comparison to known linings such as fiber cement boards, since no special, complex stockpiling of the lining, possibly in different sizes, is necessary, but the coating can be flexibly applied according to the size of the insulating board. A further advantage of such a coating is that it is very thin compared to the known laminations and can therefore also be implemented very easily. Polyurea in particular crosslinks very quickly, so the drying and production times of the prefabricated insulation advantageously be reduced. In addition, the insulation according to the invention is at least 50% lighter than known insulation according to the prior art, which further simplifies assembly in a particularly advantageous manner. At the same time, the coating according to the invention is advantageously very durable and adheres very well to XPS in particular.

Such a polyurea coating preferably has at least two components, a base component and a cover component, in particular a top spray. The base component and/or the cover component can be selected in particular with regard to their color, with the base component and/or the cover component particularly preferably being colorless and/or transparent. In this way, a color design of the lamination and thus of the insulation is made possible in an advantageous manner. The components are particularly preferably mixed beforehand and then applied together as a coating, or applied one after the other, with the base component being applied first. Most preferably, the base component dries before the top component is applied. The cover component is preferably designed in such a way that it has UV protection.

Preferably, the insulating board has at least one recess, in particular a recess, the dimensions of which correspond in particular to an opening in the building wall, e.g. a window.

The coating is preferably provided at least on the outer visible side of the insulating panel. The coating is particularly preferably also provided on the outer and/or inner edge surfaces. The person skilled in the art understands that the insulation generally has a planar extension with a specific depth. One side of the insulation is placed on the building wall, the opposite side thus faces outwards and is therefore also referred to as the visible side. In the envisaged arrangement, the insulation has outer edge surfaces at the top, bottom and sides, and preferably corresponding inner edge surfaces on the inside of the recess or recess. Particularly preferred are all surfaces of the insulation board with the Provide lamination, most preferably all surfaces except for the area intended for installation on the building wall.

The insulating board preferably has a structured surface on its side facing the building wall, the surface being particularly preferably structured, in particular structured in a waffle shape. This advantageously provides a larger surface, so that there is a better, in particular cohesive, connection to the building wall and in particular to a layer arranged on the building wall, for example a scratch coat and/or thick coating.

When using such an insulation, there is no need for an additional on-site sealing of the insulation board, which in turn also reduces the drying and assembly times on the construction site in a particularly advantageous manner. Alternatively, there is at least no need for an additional seal on the on-site surface of the insulating board. In this case, a seal, in particular a thick coating, is preferably provided at least on the lateral edges, i.e. the lateral surfaces of the insulation board and in particular at least in the lateral transition area between the insulation board and the building wall, particularly preferably also on a lower and/or upper edge. Even with such a seal, there are considerable time savings during assembly, since with the known insulation the entire surface of the fiber cement panels must be sealed beforehand, for example with a thick coating, and then have to dry for 24 hours before further processing and/or assembly.

According to a preferred embodiment of the present invention, it is provided that the coating has a thickness of 0.5 mm to 2.5 mm, preferably 1.0 mm to 2.0 mm, in particular 1.5 mm. Such a comparatively thin coating is already sufficient to reliably seal the insulation or the building to which the insulation is attached, in particular in combination with an edge seal, as described in the previous paragraph, against water and other relevant weather influences. It is also immediately apparent that such a thin coating is advantageous at the same time results in a low weight of the lining, which considerably simplifies the handling of the insulation and the installation on the construction site.

Tests by the applicant have shown that a minimum coating thickness of 0.8 mm is particularly advantageous. The coating particularly preferably has a thickness of 1 mm, there being in particular a production-related tolerance of 30%, so that the coating particularly preferably has a thickness of 1.0 mm to 1.3 mm.

According to a preferred embodiment, it is provided that the lamination is materially connected to the insulation board. During the coating, the material of the lining particularly preferably enters into a chemical bond with the material of the insulating board, in particular at least in a layer close to the surface. In this way, a backflow-proof insulation is provided in a particularly advantageous manner.

According to a further preferred embodiment of the present invention, it is provided that the insulating panel has a thickness of 80 mm to 300 mm, in particular 100 mm, 120 mm, 140 mm, 160 mm, 180 mm or 200 mm. Advantageously, such a thickness is perfectly sufficient to allow the building to be adequately thermally insulated while at the same time ensuring that the insulation weighs as little as possible, while ensuring sufficient stability for fixing the skylight. The graduated thicknesses make it possible in an advantageous manner that insulation panels can be provided in standardized sizes. Those skilled in the art understand that other thicknesses, preferably in discrete 20 mm increments, are also possible. In particular, the thickness of the insulation board is 220mm, 240mm, 260mm, 280mm or 300mm.

The insulation board is preferably provided in one piece. This means that in particular a recess is made in the insulation board. Alternatively, the insulating board is provided in several pieces. In this case, the insulating panel consists of several pieces which are connected to one another in particular in a form-fitting, force-fitting and/or material-locking manner, for example glued. The insulation board is particularly preferred initially provided in several pieces, for example having height and width dimensions of 600mmx1200mm. The pieces are then very particularly preferably cut to size and connected to one another in a non-positive, form-fitting and/or material-locking manner, in particular glued, that the insulating board according to the invention, in particular with a recess, is produced.

According to yet another preferred embodiment of the present invention, it is provided that the insulating board is made of extruded polystyrene foam (hereinafter abbreviated as XPS). XPS is a closed-cell, hard insulating material made from polystyrene, with XPS advantageously having high mechanical strength and high insensitivity to moisture. XPS is therefore particularly suitable as an insulating material in the ground. Furthermore, the combination of an XPS insulation board with a polyurea coating is advantageous, since in this case the coating is completely bonded to the insulation material and thus a one-piece insulation is provided, which in turn has an advantageous effect on the mechanical stability.

According to a preferred embodiment it is provided that the insulation, in particular the insulation board, is materially connected to the building wall made of fresh concrete, in particular in the window area. As a result, the tightness of the thermal insulation is further improved in an advantageous manner.

According to a preferred embodiment, it is provided that the thermal insulation and/or the insulation is designed in such a way that a light shaft attached to it can be walked on and/or driven on. Particularly preferably walkable means that the insulation and/or the light well can withstand a load of up to 1.5 kN. Even more preferably, trafficable means that the insulation and/or the light well can withstand a load of up to 6.0 kN or even up to 9 kN. In the event that traffic is to be present, the insulation is attached to the building wall, in particular by means of fasteners. If it is sufficient to be able to walk on it, it is sufficient to mount the insulation on the building wall using an adhesive.

The attachment points are preferably marked in/on the insulation and/or at least partially prefabricated, for example pre-drilled. In particular, the attachment points are marked on the lining and/or at least partially incorporated into it. Particularly preferably, at least two fastening points are present at one height, with which the light shaft can be fastened to the insulation on the right and left of an opening in the building wall. A number of attachment points, in particular four or six attachment points, are particularly preferably marked one below the other in a certain grid, particularly preferably both to the right and left of a building wall opening and/or at least partially prefabricated.

According to a particularly preferred embodiment, attachment points are marked on the insulation, in particular on the lamination, very particularly preferably marked in color. This can be done beforehand, for example during or after the installation of the insulation, or during the installation of a light shaft. In this case, the light well is preferably held up to the insulation and the attachment points are marked, in particular in color. It is also provided according to the invention that some fastening points are provided as markings ex works and that further fastening points are defined and marked during assembly of the light well. The person skilled in the art understands that assembly at the attachment points is provided in particular for light wells by the applicant, since there is coordination of the dimensions between attachment points of the light well and the attachment points of the insulation. However, the person skilled in the art understands that the light shaft can also be attached to the insulating panel outside of the attachment points.

A fastening means is at least partially arranged in these fastening points. This fastener preferably does not extend through the entire thickness of the insulation. In particular, the fastening means does not lie against the building wall and/or extends into it. The fastening means is particularly preferably a dowel, very particularly preferably a self-tapping dowel which has a corresponding Opening, especially in the insulation board cuts. The dowel connects in a non-positive and/or positive manner to the material of the insulation board and/or to the lamination. In a preferred embodiment, the dowel has a collar which, after it has been arranged in the insulation, bears against the insulating panel or the lamination. The dowel is preferably screwed into the insulating board. The person skilled in the art understands that such a plug is in particular an insulating material plug.

Preferably, the thermal insulation has an insert that is inserted between the wall and the window frame and/or the insulation and the window frame. As a result, the edges of the insulation facing the opening and/or the thermal insulation according to the invention can be protected against the ingress of water behind the insulation. In particular, such insulation is sealed against driving rain. Particularly preferably, both the window frame/insert interface and the insert/insulation interface are sealed with a sealing compound. Even more preferably, the insert is a cover frame, in particular a perimeter cover frame. Such a frame is provided to cover the window reveal. After insertion, the covering frame is preferably sealed off on the outwardly pointing sides to protect against water, in particular rain, in particular on the sides, at the top and/or at the bottom.

Another object of the present invention is a method for mounting a light shaft on a building wall provided with thermal insulation according to the invention, the insulation being arranged on the building wall, fastening means being arranged in the insulation and the light shaft being fastened to the fastening means. The decisive factor here is that the insulation is prefabricated, ie the insulation, i.e. the insulation board provided with the lamination, was produced off site, for example in a manufacturing plant, according to the required dimensions and is installed in the finished state on the site. In an advantageous manner, the installation of a light shaft is thus considerably simplified while completely avoiding thermal bridges, since the prefabricated insulation only has to be attached to the building wall, without the need for an on-site seal, for example would be required. However, there is preferably a lateral seal, in particular in the form of a thick coating. Even more preferably, sealing also takes place at a lower and/or upper edge, ie the transition between the lower or upper surface of the insulating board and the building wall. The light shaft can then be attached to the insulation by means of the attachment means, which also advantageously significantly shortens the installation time and reduces the susceptibility to errors. The insulation supports the light well completely. The light well is not directly connected to the building wall. Very particularly preferably, the light well is hung in the upper area on two fasteners, in particular screws, which are attached to attachment points of the insulation, and then connected to the insulation in the lower area with suitable fasteners, for example also screws, at attachment points. Preferably, the lower fastening points are only realized after the light shaft has been hung in place; in particular, after the light shaft has been hung in the upper fastening means, markings and/or screws are introduced into the insulation at other points. In a particularly advantageous manner, it is possible according to the method according to the invention to mount the light shaft directly on the insulation, and thus in particular on the coating, without waiting and/or drying times.

Any light shaft familiar to a person skilled in the art can be used as a light shaft. However, the light shaft is preferably made of a plastic material, in particular a glass fiber reinforced plastic material. The light shaft is particularly preferably made in two pieces, with an upper part and a lower part. Alternatively, the light well is made of a concrete material.

The person skilled in the art understands that the step of arranging the insulation on the building wall, i.e. in particular the installation of the insulation, can basically be carried out in two different ways, depending on local requirements.

A distinction is made between water pressure-tight installation or

Arrangement and a non-water pressure-tight installation, i.e. an installation in which the light well and/or the insulation is sealed against soil moisture and non-accumulating seepage water. The two variants differ in particular in that an additional seal is provided at least on parts of the transitions between the insulation and the building wall for water pressure-tight installation. Such a seal particularly preferably comprises a thick coating. Sealing is particularly preferred on the lateral surfaces of the insulation, i.e. on the lateral transitions between the building wall and the insulation. As a result, a material saving of up to 40% can be achieved in an advantageous manner by dispensing with a large-area seal compared to the prior art. Particularly in the case of a factory-prefabricated insulation according to the invention, the light shaft assembly can take place directly on the coating, which advantageously eliminates a drying time, which can be up to 24 hours in the systems according to the prior art. In the case of non-pressurized water-tight installation, the insulation according to the invention is preferably installed by the insulation being attached to the building wall by means of an adhesive, particularly preferably an installation adhesive. The insulation, in particular the insulation board, can be bonded to the building wall over the entire surface or only in predetermined areas. In particular, a lateral seal is not necessary here. In a particularly advantageous manner, this further improves the reduction in assembly time and the savings in material.

A dowel is preferably placed in the insulation. A self-tapping dowel is particularly preferably used for this purpose, which in particular cuts into the insulation and thus forms a positive and/or non-positive connection with the insulation. The dowel is screwed into the insulation, in particular the insulation board, until a collar, which is located at the end of the dowel, preferably rests against the insulation board or the lamination. Those skilled in the art understand that the dowel does not necessarily have to have a collar.

The light shaft is then preferably attached to the dowels by means of screws.

A further object of the present invention is a method for producing a prefabricated thermal insulation according to the invention, in which an insulating board, in particular made of XPS, is provided with a lamination, which is a polyurea coating, by means of a spraying method. This advantageously provides a prefabricated thermal insulation with a high resistance to water and/or the effects of the weather while at the same time being light in weight.

According to a preferred embodiment of the method according to the invention, it is provided that the spraying method is a hot spray method. Hot spray processes are proven processes with which a polyurea coating in particular can be applied in a simple and reliable manner.

figure 1 shows a building wall 1, in the present case a basement wall, in which a basement window 3 is provided. On its outside, the building wall 1 is provided with an insulation 4, a so-called perimeter insulation, with the area of the recess 2 being cut out. In the present case, this insulation 4 consists of an insulation board 4.3 made of XPS, which is glued to the building wall, and a lamination 4.2 in the form of a polyurea coating, which is located on the side facing away from the building wall 1 and is sprayed onto the insulation board 4.3 is. The insulation panel 4.3 is preferably provided with the lamination over the entire surface. Particularly preferably, every surface apart from the surface arranged on the building wall 1 has the lamination. The person skilled in the art understands that the lining 4.2 is not shown to scale in the present case, but is shown significantly enlarged for the sake of better visibility. The insulating panel 4.3 preferably has a thickness of approximately 80 mm to approximately 300 mm, in particular for example 100 mm to 200 mm, whereas the lamination 4.2 as a coating has a thickness of for example 0.8 mm to 1.5 mm.

The insulation 4 has a large number of attachment points 4.1, which cannot be seen in the present figure, which are arranged one above the other in a preferably vertical row to the right and left of the window opening 2. The fastening points 4.1, in the present case holes, are arranged at the same height on the right and left of the window. The holes to the right and left of the window are at least partially arranged in a certain, preferably the same, grid dimension. This makes it possible to arrange different types of light wells 5 and/or different sizes of light wells 5 in the area of the window opening 2 without requiring a great deal of assembly effort. The attachment points 4.1 that are not required can subsequently be sealed, for example with a sealing material, if required. The person skilled in the art recognizes that it would also be sufficient if the attachment points 4.1 were merely marked, in particular in the form of Markings, such as colored markings, and would have to be drilled with a drill, for example, into the lamination 4.2 and the insulation 4.3. Such an insulation board is also referred to as a mounting insulation board.

After the insulation has been arranged, in particular glued, on the wall 1, a fastening means is arranged in these fastening points 4.1. This fastening means is preferably a dowel, which is particularly preferably screwed in a self-tapping manner at the fastening points 4.1, in particular into the insulating board 4.3 and the lamination 4.2. This dowel is preferably screwed completely or at least preferably so far into the insulation board that a collar which may be arranged on it rests against the lamination 4.2. The dowel only extends into the insulation 4 and does not touch the building wall 1 . The building wall 1, which is located behind the insulation 4, therefore does not have to be drilled, which avoids thermal bridges. Furthermore, it is crucial that for mounting the insulation 4 on the building wall 1, preferably only a material connection, for example an adhesive layer, is necessary. Alternatively or additionally, if, for example, the light shaft 5 should be passable and is therefore exposed to considerable forces, the insulation 4 is arranged on the building wall by means of fastening means. Such fasteners can be, for example, dowels, screws, nails or other suitable fasteners.

The light well 5 is then fastened to at least two dowels located at the same height by means of screws that are screwed into the dowels. The light shaft 5 consists, for example, of a lower part and an upper part that is arranged on it so that it can be adjusted in height. The light well 5 preferably has fastening hooks, in particular both the lower part and the upper part, which interact with the screws that are arranged in the dowels in a positive and/or non-positive manner. Those skilled in the art will recognize that the light well 5 can also be made in one piece. In this case, it may then be sufficient to simply screw the light well 5 with two screws, each of which is screwed into a dowel and which are at the same height are to be attached to the insulation 4. However, the light shaft 5 is preferably arranged on the insulation 4 with four screws.

According to a preferred embodiment, the thermal insulation in the area inside the light well 5 has a cover frame, the circumference of which extends around the entire opening 2 and the cross section of which is L-shaped. This insert has the particular task of protecting the thermal insulation from mechanical influences, UV radiation and the effects of the weather, such as driving rain, but also to provide a wall opening 2 that is watertight overall, i.e. also protected against flooding, and a visually attractive opening. Such a cover frame or insert therefore supports the lamination 4.2 functionally in the form of the polyurea coating, which is already waterproof, UV-resistant and stable to the effects of the weather and protects the insulation.

figure 2 shows the thermal insulation in a section as a top view. It can again be seen that the insulation 4, ie in particular the insulation panel 4.3, has a recess 2, in particular here a cellar window opening. The basement window opening corresponds to the opening 2, which is arranged in the building wall 1. The insulation 4 is arranged on the building wall 1, in particular glued, in such a way that the opening 2 in the insulation 4 and the opening 2 in the building wall 1 are aligned with one another. Alternatively, a defined offset is provided. Consequently, the insulation 4 does not have to be pieced in the area of a window 3, but can be arranged in one piece on the building wall 1.

How from the figures 1 and 2 can be seen, the assembly of the light well 5 is therefore very simple. After the prefabricated insulation 4 has been glued to the building wall 1 and, if necessary, fastened by means of other fastening means, if necessary the window 3 has been installed, dowels are arranged at the desired marked or pre-drilled fastening points 4.1, screwed here preferably self-tapping into the insulation 4. The building wall 1 does not have to be drilled. Then the light shaft 5 is attached to the dowels by means of screws.

figure 3 shows a preferred embodiment of the prefabricated insulation 4 according to the invention. This consists of a (large-format) insulation board 4.3, preferably made of XPS, which is sprayed over the entire surface with a lamination 4.2 in the form of a polyurea coating. A hot spray method is preferably used here. Either before or after the spray application of the coating, the recess 2 is made in the building wall 1 in accordance with the shape of the basement window opening 2 . Attachment points 4.1 are provided on both sides of the recess 2, corresponding to the desired attachment height of the light shaft 5. These can be introduced before or after the lamination 4.2 is sprayed on, for example pre-drilled, or they can be pre-drawn on the lamination 4.2, in particular after it has been applied. In the present case, further fastening points 4.1 are shown in accordance with a predetermined grid. However, this is purely an example. In particular, one fastening point 4.1 on both sides of the recess 2 is sufficient for fastening the light well 5.

figure 4 shows the thermal insulation 4 according to the invention according to a further advantageous embodiment of the present invention in a schematic sectional view. The in figure 4 embodiment shown essentially in connection with figure 1 illustrated embodiment, so that reference is made to the relevant statements.

The main difference to figure 1 is that the coating 4.2 is provided both on the outward-facing front side of the insulating panel 4.3 and on the lateral surfaces. The coating 4.2 is particularly preferably also provided on the upper and/or lower surface of the insulating board 4.3. In the case of water pressure-tight installation, a seal covering the transition area between the lateral surfaces and the building wall 1, in particular a thick coating, is additionally provided, which is not shown here for the sake of clarity.

Furthermore, the insulation 4 according to figure 4 an internal perimeter cover frame 6. Such a frame is used to cover the window reveal provided. After insertion, the cover frame is preferably sealed on the outwardly facing sides to protect against water, in particular rain.

The person skilled in the art recognizes from the description, in particular the description of the figures, that the light shaft 5 can be provided in one piece, in two parts or even in three parts. In each version of the light shaft 5, this is usually covered with a grating.
