Functionalized glazing

Glazing suitable for a side or front window for an airplane or helicopter cockpit, comprising, in succession:

• a first rigid substrate (S1) comprising an outside face to be outside of the cockpit;
• a second rigid substrate (S2);
• a third rigid substrate (S3) comprising an inside face to be inside the cockpit,
• wherein the second rigid substrate (S2) positioned between the first rigid substrate (S1) and the third rigid substrate (S3),
• wherein the substrates are made of thermally semi-toughened or chemically toughened glass;
• a first active system (A) that includes at least one layer and is positioned between substrates (S1) and (S2),
• a second active system (B) that is a thin-film multilayer system comprising a heating function and positioned between the substrates (S1) and (S2),
• wherein the first substrate (S1) is set back in relation to the other two substrates (S2) and (S3) with a set back zone around the periphery of the first substrate (S1);
• and
• at least one polymer film (F1, F2) functioning as an adhesive interlayer and retaining glazing fragments should the glazing break, said film positioned between substrate (S1) and substrate (S2) and between substrate (S2) and substrate (S3), and
• a seal (J3) that encapsulates the substrates (S1), (S2) and (S3) and that covers the set back zone and periphery of the first rigid substrate (S1).
