Definitions
- the invention relates to a facade structure of buildings, such as buildings, in particular in a heat-insulating design, the facade outside being formed by a cover and a heat insulation layer being arranged between the building wall and cover, and to the production of thermal insulation.
- the object of the invention is to provide a facade structure of the generic type and a method for producing thermal insulation, wherein reflection damping or absorption of the occurring electromagnetic waves is made possible in a simple manner and thus an impairment of directional radio links and ASR systems is avoided.
- the thermal barrier layer is arranged in front of reflective components of electromagnetic waves in the area of radar waves in the outer region of the building wall and consists of absorbent material for the electromagnetic waves, which is formed from a foamed plastic as an electrical non-conductor into the electrical Conductive and / or magnetic materials are incorporated to form conductivity areas, the dimensions of which are at least 1000 times smaller in all planes than the wavelength of the electromagnetic waves to be absorbed and have a share of up to 10% of the volume of the thermal insulation layer and that the upstream cover consists of an electrical non-conductor.
- the impinging waves are essentially absorbed or damped by the conductivity regions formed, in that the energy contained is converted into heat.
- the layer thickness of the thermal insulation layer be dimensioned in such a way that the energy of the electromagnetic waves occurring on the reflecting components becomes almost zero.
- a favorable design is created in that soot particles are arranged as the electrically conductive material.
- carbonyl iron powder can be used as the magnetic material.
- the thermal barrier coating be constructed from several layers, each of which has different concentrations with electrically and / or magnetically conductive materials.
- the heat insulation layer has an additional layer of fire-retardant material for flame protection on its outside for absorption.
- a metallic grating be arranged as an antenna for reflection in the outer layer and that a subtraction can be carried out by different transit times of the reflected electromagnetic wave components.
- a method for the production of thermal insulation, consists in that a large and open-pore plastic foam is used as the basic structure for the formation of an electrical non-conductor into which is electrically and / or magnetically conductive Materials are stored by spraying and then the basic structure is foamed using a fine-cell plastic.
- a heat insulation layer 2 is applied, which is designed in the form of surface elements or sheets.
- the thermal barrier coating 2 is constructed from a foamed plastic, such as polyurethane, as an electrical non-conductor, in which electrically and / or magnetically conductive materials are embedded. These materials, such as soot particles or carbonyl iron powder, form conductivity regions whose dimensions in all planes are at least 1000 times less than the wavelength of the electromagnetic waves to be absorbed and which account for up to 10% of the volume of the thermal barrier coating.
- a layer 3 of fire-retardant material for flame protection is additionally applied to the absorbent thermal insulation layer 2 if this is not guaranteed by the thermal insulation layer 2.
- a cover 5 which forms the outside of the facade, is arranged, which consists of an electrical non-conductor, such as Resoplan, Trespa or fiber cement.
