         6 . The thermal mounting bracket as defined in  claim 1 , wherein the thermally insulating material includes a foam. 
     
     
         7 . The thermal mounting bracket as defined in  claim 1 , further comprising spacers made of a material more rigid than the thermally insulating material and insertable in the insulating material adjacent one of the mounting apertures. 
     
     
         8 . The thermal mounting bracket as defined in  claim 7 , wherein each spacer includes a ring larger in diameter than the mounting apertures. 
     
     
         9 . The thermal mounting bracket as defined in  claim 7 , wherein at least some of the mounting apertures are provided in groups, each group including mounting apertures that are closer to each other within the group compared to a distance with the mounting apertures outside of the group, each spacer includes rings larger in diameter than the mounting apertures and mechanically coupled to each other so that the spacer is positionable with each of the rings around one of the mounting apertures within the group. 
     
     
         10 . The thermal mounting bracket as defined in  claim 1 , wherein the first, second and third walls have uneven dimensions to that once a selected one of the first, second and third walls is secured to the mounting surface, the other two of the first, second and third walls protrude from the exterior wall along a distance that varies according to which one of the first, second and third walls is the selected one of the first, second and third walls. 
     
     
         11 . The thermal mounting bracket as defined in  claim 1 , further comprising a double sided tape mounted to at least one of the first, second and third walls. 
     
     
         12 . The thermal mounting bracket as defined in  claim 11 , wherein the double sided tape secures the thermally insulating material to the at least one of the first, second and third walls. 
     
     
         13 . The thermal mounting bracket as defined in  claim 11 , wherein the double sided tape includes a flap protruding from the at least one of the first, second and third walls. 
     
     
         14 . The thermal mounting bracket as defined in  claim 1 , wherein each of the first, second and third walls defines two free edges, each of the two free edges being provided with alignment notches extending thereinto. 
     
     
         15 . The thermal mounting bracket as defined in  claim 1 , wherein at least three of the mounting apertures are arranged in an equilateral triangular configuration. 
     
     
         16 . A thermal mounting bracket securable to an exterior wall of a building, the thermal mounting bracket comprising:
 first, second and third walls pairwise perpendicular to each other forming a corner,   at least one of the first, second and third walls defining mounting apertures for receiving a fastener usable to mount the bracket to the exterior wall;   the at least one of the first second and third walls being covered with a thermally insulating materials.   
     
     
         17 . A system for mounting insulation panels to an exterior wall of a building, the system comprising:
 a plurality of thermal mounting brackets secured to the exterior wall; and   a plurality of elongated girts each mountable to a selected subset of the thermal mounting brackets,   wherein the thermal mounting bracket includes
