SE461340B - MINERAL FIBER PRODUCT LIKE AN INSULATION PLATE OR INSULATION COAT - Google Patents

Description

10 15 20 25 30 35 461 340 z becomes flammable. Finally, a multilayer plate for light building purposes previously known from DE-OS 33 15 901, consisting of a main layer of rock or glass wool, which plate has one or two coats of magnesia or cementitious wood wool.

Apart from the flammability of this product, it moves in the case of fixed plates which can neither be bent nor wound. to to achieve a non-combustible construction technique, cost-effective mineral fiber product according to the preamble of claim 1, This is where the invention that has purpose which has the required volume weight for containing one specific thermal conductivity group according to DIN 18165 (example group 040 or 035), but is still dimensionally stable in such way of very good handling and fastening, for example by means of plugs on building walls of this product secured asked.

According to the present invention, this object is solved easily by means of a mineral fiber product, such as insulating plate or insulating web, which product has a main layer of one mineral fiber layer with a bulk density of 5 40 kg / ms, on which one pressure-distributed cover layer in the form of a flexible plastic non-deformable surface metal is packaged, the cover layer being a glass nonwoven fabric with such a basis weight that the main layer despite its relative low volume weight is dimensionally stable together with the cover layer.

An insulating plate or insulating path constructed in this way relative to the state of the art has a number of significant advantages, whereby the mineral fiber layer serving as the main layer becomes so rigid through the packaged cover layer that it is possible it is possible to arrange only the volume weight which is dimensioning for a specific thermal conductivity group, ie that it otherwise in rule only for achieving a certain stability for the insulation board or insulation web use higher volume weight is not long required. In this case, it is particularly advantageous if you use a fiberglass roll as a cover layer which has a basis weight of 30 to 110 g / m2. Furthermore, the glass wool should be diffusion opioid should be its tangled glass fibers for fire technical reasons be tied to each other by means of a organic binder which is limited in its amount.

Especially in the use of the invention according to the invention. the clay slab for aerated building facades would, for example, 10 15 20 25 30 35 461 340 show a product that falls within the thermal conductivity group 040 at a bulk density of 15 kg / m3 give the same dimensional stability as a corresponding product without pressure-distributing cover layer with a bulk density of 25 kg / m3. In addition to this weight saving is excellent the new insulating plate further of a high bending stiffness, i.e. at overhanging structure, it does not crack, which enables one simpler installation on the construction site, for example at high winds speeds.

When using the insulating plates according to the invention for ventilated facades - hereinafter referred to briefly facade insulation plate - obtained through the provided cover layer at the same time a firmer surface on the weather side so that fiber is lost can not be done either during assembly or during operation; furthermore, the outer cover layer will be take reject any slqgægn- Finally, greater is made possible dimensions in comparison with previous facade insulation tiles, please neither the improved rigidity, which reduces the joints and thus the number of anchors commonly used for attachment thereof. The latter advantage is of course also present when the plate size remains the same as that of the previous shaped plates, because the cover layer acts as a pressure distributor.

Finally, it is possible with the facade insulation panels according to the invention better smooth out irregularities in the underside of the exposed façade wall law, since the main layer has a lower bulk density than before ie, it can thereby advantageously equalize the building ranser.

In the case of a design of the invention according to the invention, the ralfiber product in the form of an insulating web and thereby when using the insulating web for a so-called core insulation, ie as insulation between building walls made of two shells, can the volume weight of the main layer is advantageously selected to between 10 and 30 kg / m3, with two preferred products having a bulk density of 15 and 25 kg / m3, respectively. In this case, it is of a row benefits, such as reduction of transport and warehousing costs, fewer joints and thus fewer thermal bridges, it is appropriate to roll the insulating web as a precursor to a roll, which can have a length of 3 to 10 m. This circumstance is made possible due to the raw density of the main layer which is lower than hitherto against in view of the fact that the main layer thereby makes it easier to communicate 14 "! 10 15 20 25 30 35 461 340 primeras.

Further details and advantages of the invention will become apparent. more in the following to be seen in more detail and described in connection to the embodiments shown in the drawing.

Pig. 1 is a perspective view of a mineral fiber product in but of a facade insulation board with one on one side pákascherat cover layer.

Pig. Z shows a cross section through a building wall with a rear-ventilated facade cladding according to section II-II in Fig. 3 vid which facade insulation plate according to Pig. 1 is arranged.

Pig. 3 shows in a perspective view a corner area of a building with a not yet fully completed rear-ventilated façade cladding, in which a facade insulation board according to Pig. 1 is used. r ' Pig. 4 shows a cross section through a two-shell design building wall, which as a further exemplary embodiment shows an insulating web with a cover layer packaged on one side such as s.k. core insulating blanket.

On Pig. 1 shows an insulating plate 1 which has one main layer 2 and a cover layer 3 packed thereon. the main layer 2 of the plate 1 consists of and bound with phenolic resin hydrophobicized glass fibers and in the present case have such as s.k. facade insulation board preferably has a bulk density of 15 kg / m3.

As a cover layer, a vapor diffusion-open glass wool blanket serves as has a basis weight of about SO g / m and whose in virnwwr present glass fibers are connected to each other by means of one to its quantity limited organic binder. Of course, the main layer 2 also consist of rock fibers or other mineral fibers.

The insulating plate 1, as in the present exemplary embodiment according to Pig. Z and 3 serve to insulate behind ventilated facades, have normally a plate dimension of 1250 x 600 mm, whereby the plate thickness the gap here is suitably stepped from 30 to 100 mm, i.e. the game depends on the use case in question and on it desired value with respect to the heat resistance. Insulating plate 1 falls within the heat conduction group 040 according to DIN 18165 odxharen high stiffness. Furthermore, it meets the requirements for the building material class A2, which according to DIN 4102 means non-combustibility.

On Pig. 2 shows a cross section through building wall 4 as has an aerated facade cladding 5. Such a cladding serves well 10 15 20 25 30 35 5 461 s4ø to provide thermal insulation as well as to provide sound insulation and, in addition, it must have an appearance which is politically appealing. It shall fulfill these functions during all ambient conditions and moreover do not change with the time.

The insulating layer in the facade cladding 5 according to Pig. 2 and 3 is always formed by a plurality of adjacent arrangements. insulated plates 1, which by means of per se known so-called pine- national anchors 6 are attached to the building wall 4 and then with to the covering cover layer 3. Then follows the actual façade the cladding, for example in the form of panels L which again with help with suitable anchors 8 are so held against the nadsväggen 4 attdet: fl hblhren aeration gap 9 between these panels 7 and the insulating plates 1. Through the inventive units the dimensional accuracy of the insulating plates 1 it is possible to guarantee an aeration gap 9 of, for example, 2 cm. In addition thanks to the dimensional stability of the insulating plates 1, it is possible to reduce the tolerances provided so far for such air columns; this is also due to the fact that they have been used so far the facade insulation panels, which have no cover layer, have soft flat corners so that \ dd'æuänàüng of the plate anchorage rings 6 in the corner joint areas indicated by Fig. 3 with 10 flat corners would the plate of the device and thus not only optically be able to be driven away from be disruptive to the building inspection but would also constitute thermal engineering fault points and reduce the ventilation gap 9.

These disadvantages are now eliminated by the invention arranged the cover layer 3, since the insulating plates 1 tackiære the cover layer has an excellent edge strength so that the insulating plate the towers 1 can be impeccably retained especially in the corner joint areas 10.

Thanks to the arranged cover layer 3, a better re assembly control, ie. through the hitherto attachment of the fastener freely, it cannot be ruled out that any fasteners elements 6 and 21, respectively, were set too deep. The result was again that such insulation boards locally became too tight man-printed, whereby the spring insulation ability was impaired in these areas; furthermore, a worse overall picture was obtained. O 10 15 20 25 30 35 461 340 e Nowadays, on the other hand, the anchors are set too deeply 6 shows a deformation of the surface layer 3, which becomes visible through the creasing so that there is an opportunity for a better assembly. Control.

On Pig. 4 is shown as a further embodiment in two shells a building wall comprising an inner shell 11 and an outer shell 12, between which an insulating web 13 with eu: on one side the coated cover layer 3 is inserted as so-called nuclear insulators blanket. The construction of a two-scale masonry with intermediate known mineral fiber thermal insulation layers offer as known through the clear functional separation in load-bearing structures, insulation and moisture protection the building physics ideal solution for the building part outer wall. In the present embodiment the insulating web 13 is arranged without any specially arranged air gap between the outer shell 12 and the insulating web 13. This is possible on one side since the main layer 2 of the insulating web 13 is hydrophobicized and on the other hand possible because the cover layer 3 downwards diverts any moisture that penetrates through the outer shell 12.

The outer shell 12 is held in the usual manner at the inner shell 11 with or wire anchor 14, whereby the insulating web 13 must be knitted over the wire anchors 14 before the raising of the outer shell 12.

After applying the insulating web 13 to the wire anchors 14 pâstickes on these städse s.k. draining discs 15, which simultaneously can advantageously be used for setting a particular thickness limitation for the insulating layer 13.

In the present embodiment, the iymvikfen for the insulation layer 13 main layer: z from 23 kg / m3 to 15 kg / m3 by using the cover layer 3 in the form of a glass wool rug with a basis weight of 50 g / m2, in both cases the requirements are met, for example, with respect to thermal conductivity group 040.

When using a pc. wool carpet laminated core non- clay felt such as insulation between two-scale building walls is it is particularly advantageous to use insulating webs of one length of 3 to 10 m, which as a precursor are wound up into a roll. In addition to facilitating installation and offering fewer joints and thus fewer heating bridges, you can without it problems insulating wall corners because the wool carpet laminate due of its flexibility in combination with the relatively small volume 10 15 20 461 340 7 the weight of the main layer of the insulating web can be easily gas around wall corners, ie can sneak up on these.

In summary, the basics of the present invention are in the case of a mineral fiber product, only the volume weight required for placement in a particular heating joint ~ capacity group according to DIN 18165, whereby a required dimensional stability of the product by the application of a suitable cover layer. This suggests that this basic idea can also be realized for other reversal cases than those described herein; for example in so-called indu- strip cover plates for a visible mounting in so-called standard grid-T- rails. In such isolation measures, for example, it is also possible is intended to provide surface surfaces on the laid industrial cover plates. an additional insulation of loosely applied mineral fiber felt, so that they use the cover plates for this extra load may have to be made in a higher volume weight than ting of the self-stresses. This has been thought of, for example a volume weight of S0 kg / ms, which should still be be within the scope that can be considered to belong to the invention.

The same also applies to the dimensioning of the surface of the cover layer. weight. Furthermore, it is possible to use it according to the invention the basic idea of insulating plates, which are applied, for example, between rafters. This means that the basic principle of the invention the tank can be applied in several use cases.
