Abstract
Coupling system (3, 30) for coupling building panels (1, 2; 31, 32) or sandwich panel comprising two cover sheets (5, 6; 33, 34, 36, 37) and a core (4, 39) of insulating material sandwiched between the two cover sheets, in particular for building a roof structure. The building panels have matching coupling edges (7, 8; 40, 41), profiled to define one or more water discharge channels (19; 59, 64) running substantially parallel to the coupling edges.
