Description

Insulation for clamping fixtures between roof rafters or beams of other wooden constructions

Such insulations (or insulation elements) are known and used for clamping the installation of insulation panels cut from sheets or sheets, in particular between roof rafters, balconies or other defined surfaces. This is a market with production indices that have been growing for decades, and these insulation sheets are installed on the fly by construction professionals, but often by unskilled people, handcrafters. In particular, since insulation of steep roofs with mineral wool has become commonplace in the market, these insulation sheets, also referred to as clamping felts, have steadily increased their market share.

In producing insulation and maintaining inventory, manufacturers should generally consider that the distinct widths and heights, ie grid depths, between roof beams or beams of other wooden constructions can vary considerably. For these reasons, for example, so-called show mats for making different widths between rafters or beams are made and keep inventory in finely gradient widths, for example with a width gradient of 100 mm. Clamping felt thicknesses of about 80 mm to 220 mm or more are also provided today. This, of course, involves maintaining large inventory in production, sales and distribution, and also on the building site.

Another particular problem with these products is the required expenditure of the material, which must always be reduced for reasons of cost, but is particularly important because the wide surfaces must be covered with insulating material in preferred applications such as steep roof insulation. In addition, considerable material costs may be required, especially due to the fact that mineral wool must be produced either incrementally from biodegradable components or in accordance with special national regulations.

The present invention relates to a heat insulating material according to the preamble of claim 1.

The object of the invention is to provide a facility between roof rafters, beams or other confined surfaces, which optimizes the product for the use of the material required to meet technical service values, in particular the ability to insulate, without the loss of necessary insulation properties. It is to provide an insulation sheet or insulation panel for clamping.

In a deeper sense, the insulation for clamping the installation between beams of roof rafters or wooden frame structures saves material over conventional insulations and nevertheless not only has an optimum clamping effect but also these insulations In terms of the fact that it is distributed in the market, it should be provided with the advantages of storage, transportation and packaging through volume reduction of the packaging.

The next aspect of the invention is a thermally insulating sheet or thermal insulation within a thickness range which ensures complete thermal insulation and in particular continuous compensation at different thicknesses with an insulating material having a different constant thickness and changing the beam thickness (lattice depth). To provide a panel. This insulation sheet should nevertheless be easily manufactured and should be fitted with insulation panels or panels by simple clamping without damage.

This problem is solved according to the invention by the content contained in the characterizing part of claim 1, whereby convenient and particularly advantageous embodiments are characterized by the content contained in the dependent claims.

The present invention is mainly characterized by the fact that the insulating sheet or panel has a special clamping support element, which is also referred to below as the clamping layer. This is a significant savings in material in the entire insulation layer since it only needs to be designed in terms of its clamping possibilities to ensure that only the clamped part of the panel or sheet needed to clamp the installation is in complete support of the material. Make it possible. The remaining or remaining layer of the panel or sheet can be suitably adapted to a particularly low volume density without the aid of clamping and supporting functions, ie with a smaller elastic force than for example the clamping layer and only needs to be designed for thermal insulation. By classifying the volume density in a panel or sheet, for example, a significant material savings can be achieved by considering the fact that particularly significant surfaces must be insulated in the intended application of steep roof insulation. In a given case the properties of the clamping layer are obtained by higher volume density over the remaining layer. Higher volume densities are used here to obtain the clamping function of the clamping support element. The volume density in the remaining area of the insulation sheet or panel may be selected according to the particular required side view, in particular in terms of thermal conductivity. This clamping layer, of course, meets the need for thermal insulation.

In a particularly preferred embodiment the panel or sheet is divided into two layers, one layer of which has a greater elasticity than the remaining layer which forms a clamping layer and in particular only due to its higher volume density, which performs only a filling or insulating function. Properties such as elastic force of the support element can be achieved by appropriate adjustment of content and / or fiber quality and / or fiber orientation as well as increased volume density.

Multipart insulation in at least two parts with different properties, in particular double division, achieves material savings in accordance with the invention, while retaining or optimizing the clamping effect on conventional mineral wool insulation, whereby Acts as a clamping form. In this connection any sag occurs, for example in the weight of the insulation, between the roof rafters, so that in this case the preferably positioned clamping layer has a clamping effect on the remaining residual insulation layer below. Crazy Since the volume density of the residual insulation layer serving as the filling layer can be minimized according to the invention, not only the savings in the material but also significant packaging advantages are obtained because the product can be better compressed. This is particularly advantageous for insulation supplied in roll form, since the packaging volume is significantly reduced, resulting in reduced transport and storage volume.

It is also possible to provide two filling layers or two clamping layers in the case of only one filling layer with an embodiment of a particularly preferred double layer of insulation sheet or insulation panel. The number and arrangement of filling layers and clamping layers can be correspondingly selected by the skilled person.

As mentioned above, the properties of the clamping layer can also be adjusted by the geometry of the fiber, the position of the fiber, the form of the fiber, the orientation of the fiber, the binder content or other additives that strengthen the clamping layer, rather than by volume density. It is essential that this clamping layer has sufficient developing or elastic force to ensure the required frictional force between the clamping layer and the defined surfaces. It is generally maintained that the clamping layer is sufficiently rigid that the insulation can be secured between the rafters at a sufficient pressure and pressed against it, while the filling layer can be soft and pressurized enough to function as a thickness compensation at different grid depths. do. When the elastic force is adjusted via the volume density, it is convenient to make the ratio of the clamping layer volume density to the packed layer volume density larger than 1, preferably larger than 1.5.

Preferred embodiments of the invention will be described below with reference to the drawings.

The heat insulating material in the form of a heat insulating sheet or heat insulating panel 1 partially projected in FIG. 1 consists of two layers, a filling layer 2 indicated and a clamping layer 3 denoted by KS. These two layers have different properties and therefore also different properties. In the preferred application case, ie between the rafters of the roof construction or between the pillars of the wooden frame construction, made from mineral wool with suitable binders for clamping the installation of the insulation sheet or insulation panel 1. The layers are designed to have different volume densities. The clamping layer 3 is designed in terms of clamping the equipment of the sheet or panel at its density and in particular has a higher volume density than the filling layer 2. The filling layer can be designed irrespective of the clamping function and thus has a reduced volume density, the density of which is chosen only in terms of the desired thermal insulation properties.

FIG. 2 shows an insulating sheet 1 cut from the sheet wound with the insulating material roll according to FIG. 5 in a fitted position between two adjacent rafters 4 of a steep roof structure, with the reference sign 5 being used in the roofing operation. It is used conventionally and refers to a waterproof plate disposed on the upper surface of the rafters 4. In the illustrated embodiment of FIG. 2, the clamping layer 3 is arranged on top, ie on the roof surface, adjacent to the waterproof plate 5, while the filling layer 2 is arranged towards the room ie below. The insulation sheet 1 shown in FIG. 2 is adjusted in terms of the thickness for the thickness d3 of the rafter, but this is not necessary in this case. The layer thicknesses of the clamping layer 3 and the filling layer 2 are denoted by d1 and d2. For installation, the thermal insulation sheet 1 is cut in the roll according to FIG. 5 with an overrunning over width D between the adjacent rafters 4, which is clamped between the rafters adjacent to the insulating sheet 1. And is supported by the clamping effect. Conventional compartment useful overreaching is about 1 cm.

The two layers 2 and 3 are formed of mineral wool as mentioned above, but they differ in terms of their mechanical properties. Other properties of these are achieved in the embodiment of FIG. 2 by the different volume densities of layers 2 and 3. The filling layer 2 has a lower volume density than the volume density of the clamping layer 3. The clamping layer 3 having a higher volume density has a higher elasticity between these restricted surfaces than the filling layer 2, which elastic insulation panels can be employed between adjacent rafters without requiring special fastening means. When tightly fixed, it can be arranged. Suitable volume densities for the clamping layer are at least 10 kg / m3, and the preferred range for clamping installations between columns of rafters or wooden frame structures is in the range of 10 kg / m3 to 30 kg / m3. Density value. A particularly preferred range for the bulk density is 15 kg / m 3 to 25 kg / m 3 and a particularly preferred volume density for the clamping layer is for example in the range of 17 to 19 kg / m 3.

Insulation of roofs, such as so-called frames between rafters facing roof slopes of 60 ° or less, in particular in the case of adjusting the volume density of the clamping layer 3 in applications for the insulation of horizontal wooden grid constructions. It is essential that the layer 3 be sufficiently strong and rigid and nevertheless be elastic without buckling under the load of the insulation 1 consisting of the layers 2 and 3. In the installed position of FIG. 2 this insulation sheet may sag slightly under its load, with slight deflection or downward doubling of the insulation, in particular in the lower region of the filling layer 2, in the perbeam of the fixed insulation sheet between the rafters 4. Resulting in a spreading force. The clamping fixation of the insulating sheet fixed between the rafters 4 is made mainly by the restoring and frictional forces formed by the clamping layer 3, which is the spreading force in the filling layer 2 induced by the clamping layer 3. It is additionally supported by it, whereby the frictional forces of the filling layer 2 over the rafters 4 of course contribute to the clamping effect. The clamping is thus made in the embodiment of FIG. 2 by means of the actual clamping layer 3 whose strength is designed for the clamping function and the filling layer 2 via the spreading forces induced therein due to the sag caused by the loading of the insulating sheet.

Reverse arrangement of the insulating sheet 1 between the limited surfaces of the roof rafters or the beams of the vertical wooden frame constructions is of course possible, whereby the filling layer 2 is adjacent to the waterproof plate 5 in the roof area. Positioned and the clamping layer faces the room. However, with vertical wooden frame constructions, the filling layer (2) together with the outer surfaces of the clamping layer (3) filled with the outer surfaces of the beams (4) up to the wall panel (5), for example to the derived wooden panel It can fill the remaining space and thereby serve as a compensation layer. In other words, due to the excellent compressibility of the configured fill layer 2 having a low volume density, different beam thicknesses d3 can be connected with one and the same heat insulating material. For example, the insulation layer 1 has a thickness of 220 mm by performing a compensating function when the filling layer 2 is somewhat compressed and thus the insulation panel is integrated. You can think of connecting. The value mentioned above for the overall thickness d1 and d2 of the insulating sheet 1 is of course an example value since the thickness of the product can also be adjusted according to the depths of the other grids. It is also possible to use two products of different thicknesses with uniform gradients or three products of different thicknesses with uniform gradients if necessary. This ultimately depends on the behavior of the market, in particular the expected differences in the thickness of the rafters or beams used in each construction. This is a corresponding examination of building codes and can vary from country to country.

3 and 4 show installation conditions for insulation panels or insulation sheets, for example, between building walls, vertical wooden frame constructions having pillars or beams used in prefabricated room modules, especially for industrial use. In an almost illustrative manner the outer surface is here indicated as a wall panel or paneled wall 5 'of the derived wood product. 3 shows the beginning of the installation process, in which a filling layer formed as a compensation layer 2 'is located in the space between the two beams 4'. The clamping layer 3 is then applied to the beams 4 by the application of force P to fill and extend to the outer surface or outer end of the beams 4 'as shown in FIG. 4 of the outer surface of the clamping layer 3. Pressurized between '). When the clamping layer 3 is pressurized, the compensation layer 2 'can also be pressed together and the other beam thicknesses can be connected to the same product as one place, i.e. it has insulation of the same thickness, thus providing a compensation function together with the insulation function. Perform. In the case of this application the clamping layer 3 is reconfigured to have a higher strength, in particular a higher volume density, over the compensation layer 2 ', and the above-mentioned ranges can be applied here as well. In both applications to the packed bed the bulk density is at least 30 kg / m 3, in particular 15 kg / m 3 or less and preferably 10 kg / m 3 or less, these two volume densities being clamped to the packed bed volume density. They are coordinated with each other so that the ratio of the layer volume density is larger than one.

The specific thickness d1 of the clamping layer 3 is minimized to the technically required thickness required to fix the thermal insulation layer between the corresponding limiting surfaces of the roof rafters or wooden grid constructions in all applications. Specific values for the thicknesses depend on the construction of the wooden frame construction and in particular on the connecting width between adjacent rafters or beams. It is generally advantageous to be able to squeeze more than the clamping layer 2 with respect to the filling layer 2, which enables on the one hand the compensation function described above but on the other hand also offers the advantages of packaging in particular. It is thus possible to realize an insulating roll having a reduced diameter but having the same length as the insulating sheet, which reduces the packaging volume and thus offers significant transport and storage advantages. The insulating sheet in the form of a roll may be extruded in the range of 1: 2.5 to 1: 4.5. With this insulation sheet or insulation panel board a classification of thermal conduction class 046 according to DIN 18165 can also be obtained, which fill layer belongs to thermal conduction 045 due to its volume density and the clamping layer is at its volume density. By means of which it is placed in thermal conduction 035 while in the middle of the insulation panel or insulation sheet meets the criteria of thermal conduction 040 according to DIN 19165. By selection of suitable volume densities RD, the formula of (lambda) lambda = F (RD) is well known and it is also possible to obtain the total thermal conductivity 035.

FIG. 5 shows a particularly preferred embodiment, a thermal insulation sheet wound with a roll to clamp the installation between the limited surfaces of the rafters or beams, especially the steep roof rafters. The insulation sheet 6 is shown in a partially unfolded state. The number 2 again represents the filling layer with a compensating function and the number 3 represents the clamping layer, which here is arranged on the outer surface at the wound position of the insulation roll. This clamping layer can also be arranged internally in the wound position, which depends on the application in accordance with the statement according to FIG. 2, ie the actual installation conditions. On the surface 7 of the layer laid on the inner surface in the wound position is the filling layer of the embodiment mentioned here, with the marking lines 8 extending perpendicular to the side ends 9 of the insulating sheet 6. In this case the display lines 8 are applied at the same distance and the distance d between two adjacent display lines is preferably 100 mm. As shown in FIG. 5, the display lines 8 need not be represented by solid lines and may also be drawn as broken lines. The indicator lines 8 are not formed as conveniently cut gold or the like and are mainly optically made so as not to affect the handling and the effect of the mineral wool sheet 6 material. The tip of the thermal insulation sheet 6 along the marking lines 8, taking into account the excessive roughness of, for example, 1 cm, necessary for press fitting and cutting at 11 to fill a section having a given width of 700 mm, for example. Starting from 10), measure the longitudinal portion L with a length of 710 mm. For this purpose, the scissors 12 are placed on the cutting line measured by the method shown in FIG. 5 and the material is dragged in the direction of the arrow 13 parallel to the adjacent display line 8.

The cut insulation panel 14 is thus rotated for installation such that the side ends 9 of the insulation sheet 6 go up and down and determine the width of the mineral face panel 14 according to the longitudinal part L. . In this position the mineral wool panel 14 is inserted into the compartment between two adjacent rafter 4. Excessive projection of longitudinal part L over compartment width D in installations of 10 mm or more in this example This results in the desired press fit of the mineral face panel 14. After insertion between the rafters 4 the mineral wool panel 14 is thus pressed together between the rafters through the clamping effect. The molded insulation sheet 6 can therefore be used as a uniform width if the panel 14 is cut from the insulation sheet according to the width D between the rafters to be placed in compartments with different widths D between adjacent rafters. have. The insulation sheet shown in FIG. 5 as a uniform width dimension of the insulation sheet for the compartments or bays with different width D and rafters and beam thickness d3 due to the possibility of simultaneous compensation and the uniform thickness of the insulation sheet. Can be used. This means that the insulation sheet 6 no longer needs to be maintained in finely graded thicknesses and that one insulation sheet of uniform width and thickness has a different width between the rafters or beams and has different enclosure depths. The ability to cover roof and wooden frame structures results in significant savings by classification.

Figure 6 shows the savings potential of the insulation in percentage over conventional insulation sheets available on the market. In particular, the thickness of the insulating sheet or panel habitually used in insulating roofs can be significantly reduced in the range of 10 to 23%, which significantly reduces the material in terms of the amount of insulating sheet used annually for insulating purposes.

Table 1 shows, by way of example, variations of layer combinations by different thicknesses, bulk densities and weights per unit area of each sublayer,

This table shows that all the variants according to the invention have a lower weight per unit area than the reference and thus result in significant savings in the material. Also, the layer thickness, volume density and weight per unit area of the sublayers can be changed thereby.

If the filling layer is adjusted so that its thickness can be extruded during installation, for example, depending on the height of the rafters or the depth of the wooden lattice, it will not only save material to a lesser extent, but also optimize the sorting. Therefore, it can be seen that in Table 1, for example, a material of 0.06 kg / m 2 can be saved compared to a standard sheet / panel having a thickness of 220 mm and a weight per unit area of 2.88 kg / m 2. The advantage in this example is mainly in the optimized classification. Even more pronounced material savings are given, for example, as a non-thickness d3 of 200 mm, but here, in variant 3, the weight per unit area on the basis of 3.00 kg / m 2 is 220 mm thick and the weight per unit area of 2.82 kg / m 2. It is considerably higher than that. The savings in the material are therefore 0.18 kg / m 3 in this example.

Multipart insulation in at least two parts with different properties, in particular double division, achieves material savings in accordance with the invention, while retaining or optimizing the clamping effect on conventional mineral wool insulation, whereby Acts as a clamping form. In this connection any sag occurs, for example in the weight of the insulation, between the roof rafters, so that in this case the preferably positioned clamping layer has a clamping effect on the remaining residual insulation layer below. Crazy Since the volume density of the residual insulation layer serving as the filling layer can be minimized according to the invention, not only the savings in the material but also significant packaging advantages are obtained because the product can be better compressed. This is particularly advantageous for insulation supplied in roll form, since the packaging volume is significantly reduced, resulting in reduced transport and storage volume.
