Abstract
A method for producing a low-emissivity layer system on at least one side of the substrate includes the steps of providing the substrate, forming at least one low-emissivity layer on at least one side of the substrate by a deposition process and briefly tempering at least one deposited layer. The electromagnetic radiation used for briefly tempering a low-emissivity layer is adjusted in such a manner that the tempered layer has layer properties comparable to those of a conventionally heat-treated low-emissivity layer of a safety glass.
Claims18
A method for producing a low-emissivity layer system on at least one side of a substrate, comprising the steps of
- providing the substrate,
- forming at least one transparent metallic IR reflection layer of the low-emissivity layer system on at least one side of the substrate by deposition,
- subsequently briefly tempering at least one deposited layer by electromagnetic radiation while avoiding immediate heating of the entire substrate,
- wherein the at least one transparent metallic IR reflection layer is briefly tempered, wherein the electromagnetic radiation for brief tempering is set in such a way that sheet resistance and thus absorption in an infrared spectral range and/or a transmission in a visible spectral range and/or spectral reflection of the low-emissivity layer system are set to values such as those of a conventionally heat-treated low-emissivity layer system of a safety glass.
