  • the first and second lateral faces are profiled so that in the closed position of the door, the portion (23A ') of the first lateral face (23') extending between the first edge (26 ') and the first longitudinal face (21 ') has a portion adapted to touch at least a portion (24A) of the second lateral face (24') extending between the second edge (27 ') and the first longitudinal face (21) of an adjacent lamella (2a), while the portion (24A ') of the second lateral face (24') of the lamella under consideration (2) extending between the first edge (26 ') and the first longitudinal face (21') ) has a portion (24A ') adapted to touch at least a portion (23A) of the portion of the first side face (23') extending between the first edge (26 ') and the first longitudinal face (21') another adjacent lamella (2ter).
  • the protrusion 27 ' has the shape of a groove with hook engaged in the groove 26'. Said protuberances and grooves serve as means for holding the slats together.
  • the first edge (26 ') of the respective lamella (2) and the second edge (27') of the adjacent lamella (2a) are adapted to each other to allow at least a relative displacement of limited spacing of the lamella considered (2) with respect to said adjacent lamella (2a), and the second edge (27 ') of the lamella considered (2') and the first edge (26 ') of another adjacent lamella (2ter) are adapted to each other to allow at least a relative displacement limited distance of the lamella considered (2) relative to said other adjacent lamella (2ter).
  • first and second lateral faces are profiled so that in the closed position of the door, the portion (23B) of the first lateral face (23) extending between the first edge (26 ') and the second longitudinal face (22) has a portion adapted to touch at least one portion (24B) of the second lateral face (24) extending between the metal profile (30) and the second longitudinal face (22) of an adjacent lamella (2a), while the portion (24B) of the second lateral face (24) of the considered lamella (2) extending between the second edge (27 ') and the second longitudinal face (22) has a portion (24B ) adapted to touch at least one portion (23B) of the portion of the first side face (23) extending between the first edge (26 ') and the second longitudinal face (22) of another adjacent face (2ter) .
  • the chamber located between the walls 21 'and 22' is advantageously divided into several sub-chambers by reinforcements 202 extending between said walls 21 'and 22'.
