         9 . Cladding system as claimed in  claim 8 , wherein the coupling element is shaped as an empty rectangular section that comprises a first threaded hole to screw the threaded pin and a second threaded hole to tighten screws used to fix the said finish panels. 
     
     
         10 . Cladding system as claimed in  claim 1 , further comprising a modular structure composed of the following modules:
 a first module comprising a rod with a double “T” shaped cross-section formed of two symmetrically opposite wings that are a front longitudinal wall and a back longitudinal wall of said rod and are connected along the central line by a partition in perpendicular position, from which at least one pair of ribs protrude on both sides, each of the at least one pair of ribs defining a longitudinal conduit arranged to receive one of the borders of an adjacent insulation panel; said rod having a top with a flat profile from which a cross-shaped rib obtained on said partition protrudes, and at the lower end, with a wedge-shaped profile, from which said back longitudinal wall extends to the end of the rod and front longitudinal wall is interrupted at a higher height, whereas the lower ends of said intermediate pairs of ribs have scaled height between the two lateral walls; said rod being provided with a series of cylindrical holes with horizontal axis across the entire cross-section of the rod in correspondence with said partition;   a second module comprising a rod provided with a double “T” shaped cross-section formed of two symmetrically opposite wings that are a front longitudinal wall and a back longitudinal wall of said rod and are connected along the central line by a partition in perpendicular position from which at least two pairs of ribs protrude on both sides, each of the at least one pair of ribs defining a longitudinal conduit that receives one of the borders of an adjacent insulation panel; said rod being provided with two flat ends, in which said partition has a top with a cross-shaped rib, in accordance with the cross-shaped rib on top of said first module, and with a corresponding cross-shaped impression at the base; said rod being provided with a series of cylindrical holes with horizontal axis across the entire cross-section of the rod in correspondence with said partition.   
     
     
         11 . Installation method of non self-bearing insulation panels on building walls, in which each insulation panel is mounted on the front of the corresponding wall with interposition of a support element adapted to keep said insulation panels detached from the wall and act as fixing points for rigid finish panels designed to frontally cover and conceal said insulation panels, said support element comprising spacing elements
 wherein at least two insulation panels are arranged between said wall and said rigid finish panel and spaced out by said spacing elements in such a way to define at least three air spaces.   
     
     
         12 . Method as claimed in  claim 11 , wherein the longitudinal borders of two insulation panels are disposed on one side and on the other side of said support element.
