         2 . The panel as claimed in  claim 1 , wherein the insulating material comprises a foam material.  
     
     
         3 . The panel as claimed in  claim 1 , wherein the insulating material comprises extruded polystyrene foam.  
     
     
         4 . The panel as claimed in  claim 1 , wherein the insulating material comprises a foam material having a density of at least 15 kg/m 3 .  
     
     
         5 . The panel as claimed in  claim 1 , wherein the insulating material comprises a foam material having a density of at least 30 kg/m 3 .  
     
     
         6 . The panel as claimed in  claim 1 , wherein the insulating material comprises a foam material having a shear modulus of at least 2500 kPa.  
     
     
         7 . The panel as claimed in  claim 1 , wherein the insulating material comprises a foam material having a shear modulus of less than 16000 kPa.  
     
     
         8 . The panel as claimed in  claim 1 , wherein the insulating material comprises mineral wool.  
     
     
         9 . The panel as claimed in  claim 1 , wherein the metal sheets are at least 0.3 mm thick.  
     
     
         10 . The panel as claimed in  claim 1 , wherein the metal sheets are galvanized steel sheets.  
     
     
         11 . The panel as claimed in  claim 1 , wherein the metal sheets are bonded to the sheet of insulating material with an adhesive.  
     
     
         12 . The panel as claimed in  claim 1 , wherein at least one face of the sheet of insulating material includes a plurality of spaced apart channels extending to at least one edge of the sheet.  
     
     
         13 . The panel as claimed in  claim 1 , wherein the one or more stiffening members are selected from the group consisting of a plastic material or glass reinforced plastics material.  
     
     
         14 . The panel as claimed in  claim 1 , wherein the building block supports comprise a profiled plastics sheet bonded to one of the metal sheets.  
     
     
         15 . The panel as claimed in  claim 1 , further comprising a formation disposed along at least one edge of the panel, the formation being configured to engage with a similar formation.  
     
     
         16 . The panel as claimed in  claim 1 , further comprising formations running along opposite edges of the panel, the formations being configured to engage with a similar formation.  
     
     
         17 . The panel as claimed in  claim 15 , wherein the formation comprises a fibre reinforced resin pulltrusion.  
     
     
         18 . The panel as claimed in  claim 15 , wherein the formation includes a seal, operative to form a seal with another formation. 
 Please cancel claims  19  and  20  and add the following new claims  21  and  22 .    
     
     
         21 . The panel of  claim 1  in combination with a building.  
     
     
         22 . The panel of claim  19 , wherein the building is selected from the group consisting of a steel framed building and a timber framed building.
