The glazing unit (1) has two glass plates (3,4) and a shatterproof thermoplastic plate (2) provided between the two glass plates. An edge (2a) of the thermoplastic plate is surrounded by a U-shaped receiving groove (5) of a receiving element (6). The receiving element has a support projection (20) in the area of an edge portion of the glazing unit, where the support projection forms a contact surface of the glazing unit with the two glass plates. The thermoplastic plate is formed from polycarbonate. A spring element is designed as resilient silicon foam.
