Abstract RU 2752347 C2

FIELD: glass production.

SUBSTANCE: invention relates to multi-layer glazing, in which only one of the glass sheets forming it has a through hole. The multi-layer glazing comprises the first glass sheet and the second glass sheet glued together by means of an intermediate adhesive layer, in which the second glass sheet has a through hole. On the surface of the hole and on the peripheral surface around it, a thin sheet with a thickness of 0.01 to 0.5 mm is inserted between the intermediate adhesive layer and the second glass sheet, made of a material compatible with the manufacture and with mechanical influences, as well as with the aging of the multi-layer glazing.

EFFECT: technical result of the invention is ensuring the integrity of multi-layer glazing, one glass sheet of which has a through hole, and increasing its resistance to aging in the most unfavorable conditions.
