Abstract
Abstract Heat reflecting wall covering comprising a carrier substrate having a discontinuous metal layer thereon produced by (1) providing a brittle coating under the metal layer and then breaking up the same to also break-up the metal layer; or (2) selectively etching the metal layer to avoid any large electrically conductive areas; or (3) spraying the metal layer through a mask, such as wire mesh to obtain high ohmic resistance and subsequently covering with a veneer protection coat and a veneer coat.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
110 words
A method for the production of a heat-reflecting covering comprising coating a substrate with a metal coat in a thickness of less than 30 nanometers, a veneer protecting coat having a thickness of about 0.5-2.0 μm and a veneer coat having a thickness of about 1.5 to 2.0 μm, both of said veneer protecting coat and said veneer coat being substantially transparent in the wavelength range of 4 to 20 μm, wherein the metal-coated substrate is treated so as to cause it to create distinct breaks in the metal layer surface so that the metal layer thereon will be effectively of such high ohmic resistance as to be electrically non-conductive.
Claim 2
Independent Claim
110 words
A method for the production of a heat-reflecting covering comprising coating a substrate with a metal coat in a thickness of less than 30 nanometers, a veneer protecting coat having a thickness of about 0.5-2.0 μm and a veneer coat having a thickness of about 1.5 to 2.0 μm, both of said veneer protecting coat and said veneer coat being substantially transparent in the wavelength range of 4 to 20 μm, wherein the metal-coated substrate is treated so as to cause it to create distinct breaks in the metal layer surface so that the metal layer thereon will be effectively of such high ohmic resistance as to be electrically non-conductive.
Claim 3
Dependent Claim
23 words
The method of claim 1, wherein a coat of a brittle material is applied on the substrate before the metal coat is applied.
Claim 4
Dependent Claim
13 words
The method of claim 2, wherein the brittle coat is deformed by milling.
Claim 5
Dependent Claim
21 words
The method of claim 1, wherein the brittle coat is hardened in a predetermined pattern before the metal coat is applied.
Claim 6
Dependent Claim
18 words
The method of claim 2, wherein the brittle coat is hardened with UV radiation, IR-radiation or electron beams.
Claim 7
Dependent Claim
77 words
The method of claim 2, wherein the substrate comprises a thermoplastic material and mechanical deformation of the brittle coat is conducted by passing the coated substrate over a heated embossing roll in such a way that the substrate is in contact with the embossing roll, and that the embossing roll is kept at a temperature at which the thermoplastic material of the substrate is permanently deformable, while the brittle coat is still in a hard brittle state.
Claim 8
Dependent Claim
30 words
The method of claim 1, wherein the thin metal coat is subdivided by mechanical treatment with brushes or combs into a plurality of partial surfaces before subsequent coats are applied.
Claim 9
Dependent Claim
45 words
The method of claim 1, wherein a mask is applied on the substrate, with the metal coat vapor-deposited through the mask on the substrate in a pattern corresponding to the mask, and, after the mask is removed, said veneer-protecting coat and veneer coat are applied.
Claim 10
Dependent Claim
59 words
The method of claim 8, wherein the mask has the form of an endless wire net belt which is brought continuously in contact with the substrate in front of the vapor depositing zone, conducted together with the substrate at the same speed through the vapor depositing zone, and detached again from the substrate after leaving the vapor depositing zone.
