The invention concerns a panel (7) specially designed for a roll-up door (2) with ceiling retraction and vertical displacement such a typical garage door, said panel being designed so as to be mounted on at least another similar panel (7) pivoting about an axis parallel to the normally horizontal longitudinal direction (D) when the panel is mounted in situ. Said panel comprises first and second sidings (16, 17) defining its parallel large outer surfaces (18, 19) made rigidly integral with each other; at least a longitudinal edge (14) with continuously decreasing thickness from the panel large surfaces (18, 19) up to said edge free longitudinal end (21) having in transverse cross section a generally pseudo-triangular profile, said spandrel panel total thickness being less than 3 cm.
