FIELD: manufacturing technology.

SUBSTANCE: invention relates to glazing materials of vehicles and concerns a combined glazing panel with a multilayer composite layer and a method for production thereof. Panel comprises a multilayer composite layer between the outer panel and the inner panel, which is a laminate comprising: thermoplastic film glued with outer panel inner side; polyester film glued with surface of thermoplastic film opposite to inner side of outer panel; thermoplastic film arranged between the polyester film and the upper side of the inner panel opposite the inner side of the outer panel, and certain thickness ratios are set. Thermoplastic film and polyester film have a common edge which extends at a distance A parallel or substantially parallel to the edge of the thermoplastic film, and material of thermoplastic film fills space between edge, inner side of outer panel and located at distance A from edge in certain direction edge of thermoplastic film and fused with material of thermoplastic film, so that the edge is isolated from the surrounding medium glazing panel.

EFFECT: invention provides an exclusively reproducible technology of producing composite panels without defects.
