       10 . The system as claimed in  claim 6  wherein said elastomeric coating contains cellulosic fibers.  
   
   
       11 . The system as claimed in  claim 1  wherein said at least one insulation board has a bottom edge, and wherein said bottom edge is disposed for installing at least six inches below said grade line.  
   
   
       12 . The system as claimed in  claim 1  wherein said top edge comprises a beveled edge.  
   
   
       13 . The system as claimed in  claim 12  wherein said beveled edge comprises a bevel angle of between about 10° to about 60°.  
   
   
       14 . The system as claimed in  claim 1  further comprising a waterproof membrane for installing between said foundation and said at least one insulation board.  
   
   
       15 . The system as claimed in  claim 1  said system further comprising fasteners to attach said at least one insulation board to said foundation.  
   
   
       16 . The system as claimed in  claim 1  wherein said at least one insulation board and said coating are vapor permeable.  
   
   
       17 . A method for providing aboveground insulation, comprising: 
 applying insulating boards to cover at least a portion of the aboveground portion of a building foundation; and    coating said insulating boards with an elastomeric coating after said insulating boards have been applied to said foundation.    
   
   
       18 . A method for providing aboveground insulation, comprising: 
 applying a plurality of insulating boards each having a first face, a second face, a top edge, a bottom edge, and a pre-applied scrim on said first face to a building foundation such that said second face of each of said plurality of insulating boards is proximate to said building foundation, and such that said plurality of insulating boards covers said foundation from at least proximate to a grade line of said foundation to proximate a sill plate of said building foundation;    fastening said insulating board proximate to said bottom edge to said foundation with a plurality of fasteners;    applying mesh tape to said top edge of said insulating boards such that at least a portion of said mesh tape at said top edge of said boards contact one of said sill plate and a band board installed to said sill plate;    fastening said mesh tape to said sill plate or said band board with a plurality of fasteners; and    applying a coating over said insulating boards and said mesh tape.    
   
   
       19 . The method as claimed in  claim 18  applying mesh tape to joints between adjacent insulating boards.  
   
   
       20 . The method as claimed in  claim 18  further comprising applying a waterproof membrane to at least a portion of said foundation prior to said step of applying a plurality of insulating boards.  
   
   
       21 . The method as claimed in  claim 20  wherein said waterproof membrane is applied between said foundation and said insulating board.  
   
   
       22 . The method as claimed in  claim 20  wherein said waterproof membrane is applied by spraying said membrane on said foundation.  
   
   
       23 . The method as claimed in  claim 18  wherein said step of applying said coating to said insulating boards comprises applying said coating such that said coating has a thickness of between about 10 mils to about 60 mils when said coating is dry.  
   
   
       24 . The method as claimed in  claim 18  wherein said step of applying said coating to said insulating boards comprises applying said coating over said mesh tape at said top edge of said insulating boards such that a continuous water shedding plane on said foundation is formed.  
   
   
       25 . The method as claimed in  claim 18  wherein said step of applying said coating to said insulating board comprises applying a matte coating to said insulating boards and said mesh tape and subsequently applying an aggregate coating on said matte coating while said matte coating is wet.
