Definitions

• the invention relates to a dimensionally stable and pressure-resistant M ineralwolldämmplatte of bonded glass or rock fibers.
• the conventional mineral wool insulation boards have only a low strength seen transversely to the board level and there is a risk that the known mineral wool insulation boards will dissolve when exposed to moisture (formation of condensation).
• the only way to increase the strength of the known mineral wool insulation boards was to increase their density and proportion of binder. This makes the insulation boards heavy and expensive.
• the invention has for its object to provide an insulation board of the type mentioned, which remains sufficiently stable even with a lower density and / or lower binder content even when exposed to moisture.
• mineral wool fibers in particular glass fibers or stone fibers, are provided which extend across the surface of the insulation board and extend transversely to the plane of the insulation board and hold the fibers of the insulation board together.
• the insulating plate designed according to the invention provides the certainty that it cannot separate from one another even when moisture occurs in the plate (formation of condensation water).
• the plates according to the invention can therefore be used as full thermal insulation and as a normal plaster base (filler base).
• the known, non-sewn panels were at Voll not used thermal insulation facades or as a filler carrier in practice, because the safety of the P latte together haltes missing.
• the boards according to the invention can therefore not only be used like the known insulation boards where only high insulation capacity is important, but can also be used where it is important that the insulation boards are held together securely.
• the proportion of binder can also be reduced, with the result that the mineral wool insulation panels become even more breathable and fire-proof.
• the glass fibers or stone fibers provided according to the invention and running transversely to the planes of the insulation board can be formed by the fibers of the insulation board itself by needling the mineral wool insulation boards.
• the fibers which pass through the plate are designed as stitched seams.
• This preferred embodiment of the invention results in particularly high strength values for the dimensionally stable and pressure-resistant mineral wool insulation board.
• the formation of the fibers passing through the insulation board transversely as quilting seams allows a glass fiber fabric or glass fiber fleece lying on one or both sides of the insulation board to be particularly easily connected to the insulation board in that the glass fiber fabric or glass fiber fleece is connected to the insulation board by the quilting seams.
• the distances between the quilting seams depend on the intended use of the sewn mineral wool insulation board according to the invention and are usually 1-7 cm.
• the thick, hard-pressed rigid, pressure-resistant and form stable glass wool or rock wool insulation boards are not critical and can be 1 - 10 cm. Possible thickness values are: 1 cm, 1.5 cm, 2 cm, 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm, 5 cm, 5.5 cm, 6 cm, 7 cm, 8 cm, 9 cm and 10 cm.
• the density of the mineral wool insulation boards according to the invention can, for example, assume values between 14 0 and 250 kg / m 3 , lower values being preferred.
• Examples of densities of the inventive stitched mineral wool insulation boards are: 14 0 kg / m 3, 150 kg / m 3, 16 0 kg / m 3, 170 kg / m 3, 18 0 kg / m 3, 190 k g / m 3 to 25 0 kg / m 3 .
• the quilting seams provided in the mineral wool insulation boards according to the invention can run in different directions, square quilting being possible as well as quilting that intersect at an acute angle. It is also possible to choose the density of the stitching in one direction greater than in the other direction, the difference in the distance of the stitching in one and the other direction being, for example, 1 to 2 cm.
• the mineral wool insulation panels according to the invention can be produced by producing the quilting seams with inseparable glass fiber yarn in the hard-pressed, dimensionally stable panels by means of a sewing machine or a quilting machine. You can place a glass fiber fabric (mesh) or a glass fiber fleece on one or both sides of the mineral wool insulation board before sewing, which is then connected to the insulation boards by the seams. Similarly, you can insert a metal or plastic film between two insulation boards as a water vapor barrier and then insert the stitching.
• the mineral wool insulation board sewn according to the invention is suitable for a wide variety of uses.
• the area of application extends primarily to facades and also as a plaster base (filler base) for interiors with simultaneous thermal insulation and sound insulation.
