It is illustrated a joint system (1; 1′) for joining end portions (2; 2′) of at least one panel (3; 3′) made of pre-insulated material comprising a joining device (4; 4′; 4″) provided, at opposite parts of a longitudinal centreline plane (&pgr;) of the same, with a first (5; 5′; 5″) and a second (6; 6′; 6″) longitudinal seat, each of said seats (5; 5′; 5″, 6; 6′; 6″) being adapted to house one of said end portions (2; 2′) of said at least one panel (3; 3′), said joining device (4; 4′; 4″) comprising means (8; 8′; 8″) for being fixed to the panel (3; 3′) adapted to be engaged in a removable manner with respective fixing countermeans associated with said at least one panel (3; 3′). There are furthermore illustrated a joining means (4; 4′; 4″), a panel (3; 3′) and a duct (15; 15′) for air-conditioning systems obtained therefrom, a method for manufacturing panels (3; 3′), a method for joining the end portions (2; 2′) of panels (3; 3′) made of pre-insulated material, as well as a method for manufacturing ducts (15; 15′) for air-conditioning systems.
