Embodiment Construction

[0044] FIG. 1 shows a first embodiment of a spacer 1 . The spacer consists of a mineral fiber body 2 having two large surfaces 3 aligned at a distance from each other and running parallel. Perpendicular to the large surface 3 , the mineral fiber body 2 has four side surfaces 4 , of which two are shown in FIG. 1 . These side surfaces 4 are perpendicular to the large surface and run perpendicularly to each other.

[0045] On the upper surface 3 shown in FIG. 1 , the spacer 1 has a coating 5 of magnesium oxychloride cement.

[0046] The coating has a reinforcement layer 6 , which is produced, for example, from a planar elongated element in the form of a glass-fiber random nonwoven, which is perforated.

[0047] Furthermore, it can be seen in FIG. 1 that the coating 5 has two circular depressions 7 , which penetrate the entire coating 5 in the direction of the plane normal to the large surface 3 .

[0048] Coating 5 has a layer thickness of 5 mm. This spacer is made as a space...

Abstract

The invention relates to a thermally and acoustically insulated spacer, in particular for flat or flat-sloped roofs, made of binder-bonded mineral fibers, in particular glass fibers and / or ore Fiber, and the separator has a first large surface facing the face to be isolated, and a second large surface extending parallel to the first large surface and arranged at intervals, wherein the large surfaces are connected to each other by side surfaces , the side surfaces are arranged substantially perpendicular to each other and also to the large surfaces, and the spacer has at least one coating arranged on the surface. In order to improve this generic spacer with regard to its static properties, in particular its bending stiffness, while also taking into account its processability, the invention envisages that the coating is produced from at least one reaction product produced from a weak Calcined magnesium oxide (MgO) and at least one concentrated magnesium oxide chloride solution are produced.

Description

technical field [0001] The invention relates to an insulating element, in particular for thermal and acoustic insulation of flat or flat and sloped roofs, made of mineral fibers bonded with an adhesive, in particular glass fibers and / or The spacer is made of ore fiber, and the spacer has a first large surface facing the surface to be isolated and a second large surface extending parallel to the first large surface and arranged at a distance, wherein these large surfaces are connected to each other by side surfaces. connected, the side surfaces are arranged substantially perpendicular to each other and also to the large surfaces, and the spacer has at least one coating arranged on the surface. Background technique [0002] Insulation materials made of mineral fibers are known from the prior art, which are marketed, for example, under the name "mineral wool" and which exhibit a high temperature resistance. According to the German Industrial Standard DIN 4102-17, these insulat...
