Description

The invention relates to an internal insulation element consisting of several layers.

Efficient thermal insulation of buildings from the outside becomes increasingly important in times of high energy costs. The first choice in the thermal insulation of buildings is the external insulation. In some cases, however, such insulation outside the masonry is not possible. This can for example be the case with listed buildings or if an external insulation for technical reasons is not possible or not affordable. In such cases, there is the possibility of internal insulation. This material is applied with good thermal insulation properties from the inside to the masonry.

In times of low outdoor temperatures, the largest temperature drop between heated interior and cold outdoor area, takes place at the demarcating wall. Moisture-laden air from the interior can penetrate through the possibly existing internal insulation to the cooled wall and thus form condensate on the wall. This happens because the damp and warm indoor air cools on contact with the cold wall, the air then absorb less moisture and thus forms from the humidity of the interior of the dew point below condensed water. The condensation can then decompose masonry (and possibly internal insulation) or lead to mold growth. This process takes place initially unseen, which often causes very large damage until it is even noticed in the interior.

A known solution against this condensation on the inside of the wall is the application of a so-called vapor barrier on the inside of the inner insulation. By attaching, for example, a plastic film, the warm indoor air should be prevented from ever penetrating into and through the inner insulation.

The material used for the insulating layer is the use of polystyrene, especially in the generic Innendämmelementen widely known. This material is characterized by favorable insulation properties at a relatively low price. However, this material causes problems in fire protection, since it burns, and it also prepares when recycling the generic Innendämmelemente problems because they actually only used thermally can be. Although it is also known to use used Styrofoam as additives in the production of new polystyrene plates and the like, but then the starting material must be sufficiently pure, which is not always possible with multi-layer insulation elements.

Based on this prior art, it is an object of the invention to provide an internal insulation, which is harmless in the event of fire, and when installed in the interior of a house, for example in a room, with high insulation effect does not require much room volume.

• eine feuchtigkeitsaufnehmende, aus Speichermaterial bestehende Speicherschicht;
• Eine zwischen der Tragschicht (1) und der Speicherschicht (4) angeordneten, aus wärmedämmendem Material, dessen Wärmeleitfähigkeit kleiner 0,03 W/(m x K) ist, bestehenden Dämmschicht (2),
• sowie einer zwischen der Tragschicht und der Speicherschicht angeordneten Dampfsperr- oder Dampfbremsschicht.

The object of the invention is achieved by an inner insulation element consisting of several layers and predominantly of inorganic material, the inner insulation element having the following layers:

• a supporting layer consisting of a supporting material;
• a moisture-absorbing memory layer of memory material;
• A between the support layer (1) and the storage layer (4) arranged, from heat-insulating material whose thermal conductivity is less than 0.03 W / (mx K), consisting of insulating layer (2),
• and a vapor barrier or vapor barrier layer disposed between the base layer and the storage layer.

In the context of the invention, an internal insulation element is understood to be an insulation element that is used or installed in the interior or in the interior of a building. It can be realized for example as a plate or plate-shaped element, or also have other geometric shapes. It is preferably used for insulation purposes where condensation can occur, which can then lead to corresponding impairments or damage. Thus, the interior insulation element according to the invention, for example Also, with appropriate layer structure or arrangement, dam a hot water leading line to the interior. The application of the invention Innenendämmelementes is thus not limited to the inner dams of the (cold) house outer wall to see.

The whistle of the invention is that an existing of different layers Innendämmelement is proposed, which consists predominantly of inorganic material, ie of mineral material that is not combustible. The invention also includes solutions which allow a small proportion by weight of polymers, ie organic material, but which is so low that it is not questionable in case of fire.

According to the invention, an inner damping element is proposed which has a multilayer construction, wherein each layer is designed to be optimized for at least one specific function. This happens on the one hand by the choice of the material of the respective layer and on the other hand by the special layer structure.

The inner insulation element according to the invention has a multilayer construction. The basis of the mechanical strength of the Innendämmelementes is a support layer. This support layer may have thermal insulation properties, but the focus here is on the mechanical strength, for which poorer insulation properties are taken into account at this point. The supporting layer is thus the basis of the further construction of the inner lining element and acts as a supporting basic framework for the following layers. The insulating layer is formed according to the invention by a material with very good properties for thermal insulation. The heat-insulating material of the insulating layer has a thermal conductivity of less than 0.03 W / (mx K). Due to these good insulation properties, the thickness of the insulating layer can be chosen low, and the precious room of the room is not overly due to the shoring reduced the Innenendämmelement invention. Due to the presence of the supporting layer, a thin insulating layer also does not have a negative effect on the strength of the inner insulating element according to the invention.

Towards the interior of the insulation element is the storage layer. This storage layer consists of a diffusion-open material. The thermal insulation properties of the storage layer are lower than those of the insulating layer. Nevertheless, the storage layer also contributes to the thermal insulation between interior and exterior. The main function of the storage layer, however, is the humidity regulation of the interior or living space. The storage layer absorbs humidity that accumulates, for example, when showering, cooking or in the presence of many people in the room and stores the moisture contained therein. In times of low humidity indoors, such as e.g. In the heating period is often the case, the storage layer this moisture back to the interior and thus provides a compensating for pleasant humidity.

The inner insulation element according to the invention also has a vapor barrier or vapor barrier layer. This layer has a high water vapor diffusion resistance, making it almost close to moisture. The task of the vapor barrier or vapor barrier layer is to protect the highly insulating insulating layer from condensation.

In a preferred embodiment of the invention, this vapor barrier or vapor barrier layer is disposed between the insulating layer and the storage layer and / or between the insulating layer (2) and the carrier layer (1). According to the first variant, humid indoor air can indeed penetrate into the storage layer, which is also desirable, but not up to the insulating layer. Alternatively, it is also possible that the vapor barrier or vapor barrier layer also (or only) between the insulating layer (2) and the support layer (1) is arranged.

Due to the multi-layered construction of the internal insulation according to the invention, the advantages of different materials are skillfully combined. It is thereby achieved that an inventive Innendämmelement characterized with low overall thickness excellent insulation properties, moisture-regulating properties for the living space and sufficient mechanical strength for installation and use in the building.

Furthermore, it is advantageously provided that the inner insulation element consists exclusively of inorganic material. In this proposal, the positive property of incombustibility of the inner dam element is combined with easy recycling since the inner damming element made of mineral materials can be easily worked up in recycling and used as an aggregate in the construction industry and so on.

In a preferred embodiment of the proposal, it is provided that the support layer consists of dense carrier material. This dense substrate ensures stable construction and mechanical strength of the base course.

Furthermore, it is provided that the mechanical strength of the support layer is higher than the mechanical strength of the storage layer.

In an advantageous embodiment, it is provided that the support material has a density of> 500 kg / m ³ , preferably> 700 kg / m ³ , particularly preferably> 800 kg / m ³ .

Clever way is provided that the support material has a density <1200 kg / m ³ , in particular <1000 kg / m ³ .

The support material must have sufficient rigidity, ie a minimum density, since the support layer is responsible for the mechanical stability of the inner insulation element. On the other hand, the density must not be too high, because then the total weight of the Innendämmelementes becomes unfavorable.

For the parameter Density of the load-bearing material, an interval is also specified, which is described by an upper and lower limit.

The upper limit is, for example, the following values: 1200 kg / m ³ , 1100 kg / m ³ , 1050 kg / m ³ , 1000 kg / m ³ , 950 kg / m ³ , 900 kg / m ³ .

The lower limits are, for example, the following values: 400 kg / m ³ , 450 kg / m ³ , 500 kg / m ³ , 550 kg / m ³ , 600 kg / m ³ , 650 kg / m ³ , 700 kg / m ³ , 750 kg / m ³ , 800 kg / m ³ , 850 kg / m ³ .

The disclosure of this application includes the set of all intervals which consists of all possible combinations of the aforementioned upper and lower limits. The disclosure of this application also includes all intervals that are only limited on one side, so that have only an upper or lower limit as indicated.

In a further preferred embodiment it is provided that the support material is inorganic.

Furthermore, it is advantageously provided that the support material is clay mineral, especially calcium silicate, calcium silicate hydrate, phyllosilicate, cement, concrete, limestone, fiber or glass fiber reinforced, preferably mineral material, vermiculite or mineral foam provided. This list is not exhaustive. All these materials are characterized by the fact that they are mechanically strong, so take over the task of a support layer can. In particular, a high mechanical stability is achieved by reinforcement with fibers, for example glass fibers with a small thickness of the support layer. These fibers are introduced into a corresponding support structure, for example in cement or concrete.

Advantageously, it is provided that the heat-insulating material of the insulating layer is inorganic and / or microporous. A microporous material (as a definition in the context of this application) is thereby characterized, for example, by the fact that a large part (at least 60%, 70%, 80% or 90%) of this material is permeated by pores, in particular so-called nanopores, and a significantly lower one Proportion has a homogeneous structure. The pores may have diameters in the nanometer range, micrometer range or millimeter range.

Furthermore, it is advantageously provided in the proposal that as an insulating material silica gel (or silica), amorphous silica gel (or amorphous silica), mineral foam, calcium silicate, glass wool, rock wool, fumed silica, airgel or the like is provided. Especially the two last mentioned materials fumed silica (or also fumed silica) and airgel are characterized by very low thermal conductivities less than 0.03 W / (m × K).

In a preferred embodiment of the proposal, it is provided that the heat-insulating material has a thermal conductivity <0.025 W / (m × K), preferably <0.02 W / (m × K), particularly preferably <0.018 W / (m × K).

In particular, the above-described materials have a corresponding thermal conductivity, the insulating layer is optimized for this task.

The abovementioned materials also make it possible to realize highly efficient, ie highly insulating, internal insulation elements with a small thickness, because the insulation layer has a maximum thickness of 30 mm, preferably not more than 25 mm, particularly preferably 20 mm.

In a further variant, preference is given to a heat-insulating material of the insulating layer having a specific surface area of at least 100 m ² / g (according to BET measuring method), preferably of at least 150 m ² / g, particularly preferably of at least 200 m ² / g (according to BET) , 250 m ² / g, 300 m ² / g or at least 350 m ² / g used. Pyrogenic silica has a specific surface area of about 200 m ² / g +/- 10%.

Furthermore, it is provided that the heat-insulating material has a density of at least 100 kg / m ³ , preferably at least 150 kg / m ³ , particularly preferably more than 200 or 250 kg / m ³ .

In an advantageous embodiment, it is provided that the heat-insulating material has a density of less than 400 kg / m ³ , preferably less than 300 kg / m ³ .

For the Density parameter of the heat-insulating material, an interval is also specified, which is described by an upper and lower limit.

The upper limit is, for example, the following values: 400 kg / m ³ , 350 kg / m ³ , 300 kg / m ³ , 250 kg / m ³

The lower limits are, for example, the following values: 50 kg / m ³ , 100 kg / m ³ , 150 kg / m ³ , 200 kg / m ³ , 250 kg / m ³ , 300 kg / m ³

The disclosure of this application includes the set of all intervals which consists of all possible combinations of the aforementioned upper and lower limits. The disclosure of this application Also includes all intervals that are only limited on one side, so have only an upper or lower limit as indicated.

Advantageously, a heat-insulating material is selected with the lowest possible density, because this is favorable for a low heat conductivity. A variant of the proposals therefore provides that the heat-insulating material has a density of less than 300 kg / m ³ , preferably less than 250 kg / m ³ , particularly preferably less than 200 or 150 kg / m ³ .

It is preferably provided that an inorganic material is provided for the vapor barrier or vapor barrier layer. With regard to fire safety and easy recycling, an inorganic material offers corresponding advantages, but the invention is not limited thereto. The invention nevertheless also encompasses polymer material intended for the vapor barrier or vapor barrier layer.

Thus, on the one hand it is provided that the material of the vapor barrier or vapor barrier layer metal, for example a metal or aluminum foil or the like is provided.

On the other hand, it is contemplated that the vapor barrier or vapor barrier layer may be used as a plastic film, e.g. is formed as a thermoplastic or elastomer, in particular as PTFE, polyethylene, Plexiglas or the like.

In addition to the use of a metal foil, the use of a metal grid between the insulating layer and the storage layer and / or between the insulating layer and the supporting layer is proposed, whereby an electromagnetic shielding can be realized. The metal grid is incorporated in the vapor barrier or vapor barrier layer or laminated on the storage layer, the insulating layer or the support layer.

In a further preferred embodiment it is provided that the vapor barrier or vapor barrier layer is used as an adhesive layer, e.g. is designed as a mineral adhesive or cement-bonded system. In this advantageous variant, the Dampfsperr- or vapor barrier layer takes on an additional task, namely, it represents a mechanical bond between the support layer on the one hand and the insulating layer on the other hand. It has not been found that there are adhesive systems that, if they are applied sufficiently flat, also reliably prevent, but in any case reduce, through-diffusion of water vapor. In a further variant, it is provided that for optimal design of the vapor barrier or vapor barrier layer, the mixture of the cement-bonded adhesive is optimized. The grading curves of the cement and the sand used are coordinated so that only a small number of chambers arise during the setting with water, which is then preferably filled by a powder plastic dispersion. Therefore, such a cement-based adhesive comprises a small amount (e.g., 0.5 to 4%) of plastic.

In this case, the invention comprises not only a four-layered structure, but also an at least five-layered structure in which the vapor barrier or vapor barrier layer (with its double function!) Is arranged between the insulating layer and the storage layer and / or between the insulating layer and the carrier layer.

Furthermore, it is advantageously provided that the storage material is inorganic.

Advantageously, it is provided that the storage material clay mineral, in particular calcium silicate, phyllosilicates, vermiculite or mineral foam is provided.

Furthermore, it is advantageously provided in the proposal that the storage material is open to diffusion.

In a preferred embodiment of the proposal, it is provided that the storage material is porous, especially highly porous (more than 60%), or microporous and high capillarity, in particular capillary water absorption of at least 100 mass%, preferably at least 150 mass%, particularly preferably at least 200 or 250 mass%. For the definition of porous, or microporous, reference is made to the above. The capillary water absorption describes the ability of the storage material to absorb mass of water based on its own mass. Storage layers of calcium silicate (90% porosity) reaches a water absorption of 26 kg / m ² .

Furthermore, it is provided that the storage material is fungicidal, or the storage layer has a fungicidal coating.

In this context, it should be stated that the use of calcium silicate as a storage material is of considerable advantage. Calcium silicate is characterized by a fungicidal property, as it forms a basic environment in contact with water that reduces, prevents or avoids the colonization of mold. At the same time, it is a material with high capillarity, that is, it is capable of absorbing and storing humidity largely from the ambient air and then releasing it again when needed.

It is characterized in particular materials that can absorb at least 150 times, 250 times, 300 times, or 350 times their mass of water. Calcium silicate has such a property to absorb water.

In an advantageous embodiment, it is provided that the storage material has a density of> 150 kg / m ³ , preferably> 200 kg / m ³ , particularly preferably> 250 kg / m ³ .

Skillfully, it is provided that the storage material has a density <600 kg / m ³ , preferably <500 kg / m ³ , particularly preferably <400 kg / m ³ .

For the parameter Density of the storage material, an interval is also specified, which is described by an upper and lower limit.

The upper limit is, for example, the following values: 700 kg / m ³ , 650 kg / m ³ , 600 kg / m ³ , 550 kg / m ³ , 500 kg / m ³ , 450 kg / m ³ , 400 kg / m ³ , 350 kg / m ³

The lower limits are, for example, the following values: 100 kg / m ³ , 150 kg / m ³ , 200 kg / m ³ , 250 kg / m ³ , 300 kg / m ³

The disclosure of this application includes the set of all intervals which consists of all possible combinations of the aforementioned upper and lower limits. The disclosure of this application also includes all intervals that are only limited on one side, so that have only an upper or lower limit as indicated.

In a further preferred embodiment, it is provided that the inner insulation element is designed as an inner insulation board or plate-like. As already stated, the inner insulating element can have any geometry according to the application and is not limited to a plate or plate-like design. It is possible, for example, to provide a cross-sectionally round, semicircular, oval or even wedge-shaped design of the inner dam element.

Furthermore, it is advantageously provided that in the plate-like configuration of the inner dam element, the insulating layer protrudes slightly from the base layer and / or the storage layer. Such a configuration ensures that the insulating layer adjacent to each other Innenendämmelements form a continuous, uninterrupted insulation level. The remaining gap between the Innenendämmelementen is then filled with a corresponding filling material. This ensures that the insulating layer is closed in any case and there is no cold bridge from the interior to the cold wall.

As projecting edge or projection, it is sufficient to provide an approximately 1-5 mm wide edge on all sides. The supernatant is also negatively on the dimensions of the plate or the plate-shaped Innenendämmelements definable, this is, for example, about 2 o / oo to 10 o / oo (ie 1%) of the plate width or plate length.

Advantageously, it is provided that the steam barrier layer or vapor barrier layer arranged on the insulating layer has the same blank as the insulating layer and likewise protrudes slightly beyond the base layer and / or storage layer. Such a design ensures that the moisture-sensitive insulation layer is protected over the entire surface from moisture penetration. In particular, when hygroscopic insulation material is used, this is of considerable advantage.

Furthermore, it is advantageously provided in the proposal that the vapor barrier or vapor barrier layer is laminated on the insulating layer or the storage layer. As a result, one can save a processing step in the production of the inner dam element.

In a preferred embodiment of the proposal, it is provided that the individual layers of the inner dam element are firmly connected to each other by a plurality of connecting elements penetrating at least part of the layers. The production of the inner dam element takes place in such a way that the individual layers are arranged one above the other and then metal pins, screws, nails or the like are injected at an angle or at right angles to the planar extension of the inner dam element and thus result in a mechanically stable bond. Alternatively, it is possible that the individual layers are glued together, in which case the adhesive does not necessarily have to assume the additional task of a vapor barrier or vapor barrier layer, but this task is taken over by a separate element layer. It is then sufficient that the adhesive is applied selectively according to the mechanical load or the desired stability.

Furthermore, it is provided that the inner insulation element consists at least predominantly, preferably exclusively of non-combustible material.

In the drawing, the invention is shown schematically in particular in one embodiment. Show it:

Fig. 1

shows a three-dimensional view of a possible embodiment of a Innenendämmelements invention.

FIG. 1 shows a plate-like design of a Innenendämmelements invention in three-dimensional view. The Innendämmelement consists of four layers 1, 2, 3 and 4 wherein the uppermost layer 4 is shown here transparent to represent the underlying layer 3 can.

When installing the Innenendämmelements the support layer 1 of the Innendämmelements is aligned to the building wall. When installed, the base layer 1 thus points in the direction of the building exterior, whereas the storage layer 4 is oriented in the direction of the building interior. The base layer 1 is made of a material with high mechanical strength and has the task of providing the entire inner insulation element stability. This stability ensures that the inner insulation element retains its shape during installation and remains dimensionally stable and even when installed. In the illustrated embodiment, the support layer 1 consists of a porous calcium silicate plate with a density of> 800 kg / m ³ and a thickness of 10 mm. Of course, inventive support layers 1 made of other materials or other densities are possible.

The next layer of the illustrated Innenendämmelements, which adjoins the support layer 1 in the direction of the building inside is the insulating layer 2. The insulating layer 2 is made of heat-insulating material. The insulating layer 2 takes over the major part of the insulation function of the multilayer Innendämmelementes. Since living space is lost in the interior insulation, the goal is to achieve the thinnest possible overall thickness of the interior insulation element. For this reason, a selection of a material of low thermal conductivity value for the insulating layer is of great advantage. Such materials have the same insulating properties at lower thickness as materials with higher thermal conductivity value and higher thickness. According to the invention, insulating layers 2 have proven to be particularly favorable containing amorphous silica gel or airgel. With these materials, thermal conductivities of <0.018 W / (mx K) can be achieved. Of course, the selection of other materials for the insulating layer according to the invention is possible. Thus, calcium silicate, glass wool, rock wool or the like could be provided as a material for the insulating layer 2. At a higher thermal conductivity compared to amorphous silica sink then either the insulation properties or it increases the thickness of the insulating layer 2, if the same isolation properties are sought. In the in FIG. 1 illustrated embodiment, the insulating layer 2 has a thickness of 15 mm to 20 mm and consists of amorphous silica gel with a density of about 200 kg / m ³ or pyrogenic silica.

Towards the inside of the building, the vapor barrier or vapor barrier layer 3 follows the insulating layer 2 of the inner insulating element. This layer has the function of preventing the formation of condensation in the insulating layer 2. In the case of low outside temperatures and heated interior, the boundary region of the base layer 1 with the insulating layer 2 is the place where condensation would preferably form. The outside of the insulating layer is cold. If warm humid air from the interior can reach this point, it is possible that the dew point is not reached and condensed water condenses. By the formed condensation then there is a risk of mold growth on the outside of the insulating layer. By introducing a vapor barrier or vapor barrier layer 3, the penetration of moist indoor air into and behind the insulating layer 2 is prevented or at least greatly reduced. In order to provide a sufficiently large obstacle to moisture, materials with high water vapor diffusion resistance are particularly suitable for the vapor barrier or vapor barrier layer. In the illustrated embodiment, the vapor barrier or vapor barrier layer is an aluminum foil. Of course, other materials such as a plastic film for the vapor barrier or vapor barrier layer 3 are predictable. Likewise, it is conceivable that the vapor barrier or vapor barrier layer is not applied in film form but is laminated onto one of the adjacent layers.

In FIG. 1 It can be seen that the insulating layer 2 and the vapor barrier or vapor barrier layer on all sides something about the other Protruding layers. This has the reason that when laying several of the plate-like inner insulation elements side by side, the insulating layers 2 and the vapor barrier and vapor barrier layers 3 meet with slight mechanical overpressing. This ensures that a secure seal between the individual Innendämmelementen and no moist indoor air can pass through gaps or cracks between the Innendämmelementen in the direction of the cold outer wall.

The fourth, the building inside facing layer of Innendämmelementes is the storage layer 4. The storage layer 4 is made of a diffusion-open material, so can absorb moisture, store and release again. Since the storage layer also has heat-insulating properties, it is possible that condensation also occurs in the boundary region between storage layer 4 and vapor barrier or vapor barrier layer 3. However, moisture occurring at this point does not remain there but is released back into the interior of the room due to the diffusion-open properties of the storage layer 4. In the in FIG. 1 illustrated embodiment of the invention, the described, open-diffusion properties are realized by a storage layer 4 consisting of a porous calcium silicate board. Calcium silicate, in addition to the vapor-permeable properties, also has fungicidal properties. Due to the moisture-regulating and fungicidal properties of a storage layer 4 formed in this way, growth of mold in the region of an interior-insulating element according to the invention is scarcely possible. Of course, another material with moisture-regulating properties can also be used as the storage material; a fungicidal action could also be realized via a corresponding coating of the storage layer 4. In the in FIG. 1 illustrated embodiment, the storage layer has a thickness of about 20 mm. The porous calcium silicate used has a density of about 285 kg / m ³ .

At the in FIG. 1 illustrated embodiment of a Innenendämmelementes invention, the four layers are glued together. In another embodiment, however, it is also possible for the individual layers to be connected to one another by a plurality of connecting elements penetrating at least part of the layers. Such a frictional connection of the layers to each other would allow a structure of purely inorganic material without any glue or plastic.

The claims now filed with the application and later are without prejudice to the attainment of further protection.
