An article includes a glass substrate including two main faces defining two main surfaces separated by edges and a temporary protective layer comprising an organic polymer matrix deposited on at least one portion of a main surface of the glass substrate, wherein the temporary protective layer has a rough surface defined by a surface roughness parameter Sa, corresponding to the arithmetic mean height of the profile of the surface, of greater than 0.2 &#x3bc;m.

Item protected by a rough temporary protective cover

A glazing article, includes a substrate made of glass or made of organic substance, on the surface of which are deposited a layer or a stack of layers conferring, on the article, a functionality, in particular solar protection, thermal insulation or anticondensation properties, with a total thickness of between 5 nanometers and 400 nanometers, an organic film covering the layer or the stack of layers, the thickness of the polymer film being between 300 nanometers and 10 micrometers, wherein a texturing element is present under the layer or the stack of layers, the roughness of the surface of the texturing element being such that: the arithmetic mean deviation Ris between 50 nm and 2 micrometers, limits included, the base length Ris between 5 micrometers and 300 micrometers, limits included.

Functional glazing provided with a permanent protective film

A solar-control or thermally insulating or anticondensation-function glazing unit includes at least one substrate equipped with a stack of thin layers reflecting infrared radiation. The stack is covered with a protective polymer film made of styrene-butadiene copolymer, the thickness of the polymer film being smaller than 10 microns.
