       5 . A building construction material as recited in any one of claims  1 - 4  wherein said wood board is selected from the group consisting of solid wood board, plywood board, CDX plywood, oriented strand board, tongue and groove board, composite board, chipboard and particle board.  
   
   
       6 . A building structure having a floor portion, a wall portion, and a roof portion, wherein said roof portion comprises a building construction material as recited in  claim 1 , said building construction material having a moisture barrier that is at least 6 to 20 mil thick.  
   
   
       7 . A building structure as recited in  claim 6  wherein said floor portion comprises a building construction material as recited in  claim 1 , said building construction material having a moisture barrier that is at least 6 to 12 mil thick.  
   
   
       8 . A building structure as recited in  claim 6  wherein said wall portion comprises a building construction material as recited in  claim 1 , said building construction material having a moisture barrier that is at least 6 to 12 mil thick.  
   
   
       9 . A building structure having a floor portion, a wall portion, and a roof portion, wherein at least one portion of said building structure comprises a plurality of wood boards which have a moisture barrier permanently attached to only part of the surfaces, and wherein said moisture barrier has a non-tacky surface and comprises a non-vulcanized, modified rubber.  
   
   
       10 . A building structure as recited in  claim 9  wherein the roof portion comprises a plurality of wood boards having a moisture barrier that is at least 18 to 20 mil thick, and wherein the floor portion comprises a plurality of boards having a moisture barrier that is at least 8 to 10 mil thick, and wherein the wall portion comprises a plurality of wood boards having a moisture barrier that is at least 6 to 12 mil thick.  
   
   
       11 . A building structure as recited in any one of claims  6 - 10 , wherein the moisture barrier is permanently attached to the wood board prior to its installation in the building structure.  
   
   
       12 . A building structure as recited in any one of claims  6 - 10  wherein said wood boards are selected from the group consisting of solid wood board, plywood board, CDX plywood, oriented strand board, tongue and groove board, composite board, chipboard and particle board.  
   
   
       13 . A method of protecting a framed building structure from the damaging effects of moisture, comprising: 
 providing a building structure frame comprising a floor portion, a wall portion, and a roof portion, and having an interior space defined by the floor, wall and roof portions;    providing a building construction material comprising a board, and a moisture barrier having a non-tacky surface and comprising a non-vulcanized, cured liquid rubberized material, wherein said material is permanently attached to the board and covers only part of the surfaces of the board; and    combining said building construction material with said building structure frame to form an intermediate building structure, wherein the building construction material is installed on the building structure frame to form part of one or more of the roof, floor or wall portions of the building structure.    
   
   
       14 . A method as recited in  claim 13  wherein the building construction material is installed to form part of the roof portion, with the moisture barrier facing away from the interior space.  
   
   
       15 . A method as recited in  claim 13  wherein the building construction material is installed to form part of the wall portion with the moisture barrier facing away from the interior space.  
   
   
       16 . A method as recited in  claim 13  wherein the building construction material is installed to form part of the floor portion, with the moisture barrier facing toward the interior space.  
   
   
       17 . A method as recited in  claim 13  wherein the building construction material is installed to form part of the wall portion, with the moisture barrier facing toward the interior space.  
   
   
       18 . A method as recited in  claim 13  wherein the building construction material is installed to form part of the floor portion, with the moisture barrier facing away from the interior space.  
   
   
       19 . A building structure having an interior portion which is exposed to moisture conditions, wherein at said interior portion of said building structure comprises a plurality of wood boards which have a moisture barrier permanently attached to only part of the surfaces, and wherein said moisture barrier has a non-tacky surface and comprises a non-vulcanized, modified rubber.  
   
   
       20 . A building structure according to  claim 19 , wherein the plurality of wood boards are installed to form part of one or more of the roof, floor, or wall portions of the building structure.  
   
   
       21 . A building structure according to  claim 20 , wherein the plurality of wood boards are installed to form part of the floor portion of the building structure.  
   
   
       22 . A building structure according to  claim 20 , wherein the plurality of wood boards are installed to facing away from the interior space.  
   
   
       23 . A building structure according to  claim 20 , wherein the plurality of wood boards are installed to facing toward the interior space.  
   
   
       24 . A building structure according to  claim 20 , wherein the moisture barrier attached to the plurality of wood boards is at least 8 to 10 mil thick.  
   
   
       25 . A building structure according to  claim 20 , wherein the plurality of wood boards are selected from the group consisting of solid wood board, plywood board, CDX plywood, oriented strand board, tongue and groove board, composite board, chipboard and particle board.  
   
   
       26 . A building structure according to  claim 20 , wherein the moisture barrier is attached to the plurality of wood boards either before or after installation in the building structure.  
   
   
       27 . A building structure according to  claim 20 , wherein the moisture barrier is attached to the plurality of wood boards after installation in the building structure.
