FIELD: glass industry.
SUBSTANCE: invention relates to coated articles with low-emission coatings. In particular, disclosed is a method of making a coated article, which includes a multilayer thin-film low-emission coating, supported by a glass substrate, comprising: formation on the substrate of the low-emission coating, which includes at least the first and second infrared (IR) radiation reflecting layers containing silver, wherein each of the first and second infrared-reflecting layers is located between one or more dielectric layers, and the first infrared-reflecting layer is spaced further from the substrate, than second infrared reflecting layer; and activating each of infrared-reflecting layers using two-step processing. At that, the first processing step pre-conditioned the infrared-reflecting layers by exposing the pulsed light source in at least the first and second wavelength ranges, wherein the first wavelength range advantageously transmits energy to the first infrared-reflecting layer, and the second wavelength range advantageously transmits energy to the second infrared-reflecting layer. Second processing step is thermal treatment, which is carried out after directly or indirectly on substrate deposited all reflecting infrared radiation layers, wherein the second step follows the first step.
EFFECT: technical result is improvement of emissivity of low-emissive coatings, for example, using a two-step approach to activation of silver-deposited low-emissivity coatings deposited at room temperature.
