Cargo transportation housing comprising a flexible fast door

A housing for the transportation of a cargo comprising:

• (a) walls defining a closed inner space suitable for storing a cargo,
• (b) an opening provided in one of the walls and giving access to the closed inner space from an outer atmosphere, and further comprises a rigid door comprising one or more rigid panels which are movable to seal or unseal said opening;
• and
• (c) a flexible fast door comprising a motorized driving mechanism suitable for moving a leading edge of a flexible shutter in a first direction to close the flexible shutter and thus seal said opening, and in a second, opposite direction to open the flexible shutter and thus unseal said opening, when said opening is unsealed by the rigid door,
• wherein the flexible shutter comprises two lateral edges engaged in parallel guiding rails fixed to two parallel and opposite edges of the opening,
• wherein the rigid panel and/or the parallel edge of the opening is provided with a groove to accommodate the guiding rails, and
• wherein the guiding rail does not protrude further towards the inner of the closed inner space than the rigid panel does when the rigid panel seals the opening.
