Moisture and condensation barriers for building structures

Abstract

Moisture and condensation barriers for protecting wood from damage in building structures (particularly but not necessarily in flooring systems) include a liquid rubberized coating material coated onto some of the wood or a barrier sheet having a petroleum-based tar layer.

1 - 23 . (canceled)  
     
     
         24 . A building construction material comprising: a wood board; and a moisture and condensation barrier comprising a non-vulcanized, cured liquid rubberized coating material coated onto and covering only part of the surfaces of the wood board, the moisture and condensation barrier having a non-tacky surface and a thickness sufficient to prevent moisture and condensation from penetrating through said condensation.  
     
     
         25 . (canceled)  
     
     
         26 . A building construction material according to  claim 24  wherein the moisture and condensation barrier has about a 6-to-8-mil thickness of the non-vulcanized, cured liquid rubberized coating material.  
     
     
         27 . (canceled)  
     
     
         28 . A building construction material according to  claim 24  wherein the wood board has a generally elongated cubicle shape with six sides, and the moisture barrier entirely covers the surfaces of at least one side but not more than five sides of the wood board.  
     
     
         29 . A building construction material according to  claim 28  wherein the moisture barrier entirely covers the surface of only one side of the wood board.  
     
     
         30 . A building construction material according to  claim 28  wherein the moisture and condensation barrier entirely covers the surfaces of only three sides of the wood board.  
     
     
         31 . A building construction material for use as a barrier to moisture penetration in a building structure, comprising: a wood board; and a moisture barrier having a non-tacky surface and comprising a non-vulcanized, cured liquid rubberized coating material covering only part of the surfaces of the wood board and forming a barrier to prevent moisture penetration into the wood board.  
     
     
         32 . A building construction material according to  claim 31  wherein the moisture and condensation barrier has, about a 6-to-8-mil thickness of the non-vulcanized, cured liquid rubberized coating material.  
     
     
         33 . A building construction material according to  claim 31  wherein the wood board has a generally elongated cubicle shape with six sides, and the moisture barrier entirely covers the surfaces of at least one side but not more than five sides of the wood board.  
     
     
         34 . A building construction material according to  claim 33  wherein the moisture barrier entirely covers the surface of only one side of the wood board.  
     
     
         35 . A building construction material according to  claim 33  wherein the moisture and condensation barrier entirely covers the surfaces of only three sides of the wood board.  
     
     
         36 . A building construction material for use as a barrier to moisture penetration in a building structure, comprising: a wood board; and a moisture barrier having a non-tacky surface, comprising an elastomeric membrane comprising non-vulcanized rubber which is coated onto only part of the surfaces of the wood board and forms a barrier to prevent moisture penetration into the wood board.  
     
     
         37 . A building construction material according to  claim 36  wherein the moisture and condensation barrier has about a 6-to-8-mil thickness of the non-vulcanized, cured liquid rubberized coating material.  
     
     
         38 . A building construction material according to  claim 36  wherein the wood board has a generally elongated cubicle shape with six sides, and the moisture barrier entirely covers the surfaces of at least one side but not more than five sides of the wood board.  
     
     
         39 . A building construction material according to  claim 38  wherein the moisture barrier entirely covers the surface of only one side of the wood board.  
     
     
         40 . A building construction material according to  claim 38  wherein the moisture and condensation barrier entirely covers the surfaces of only three sides of the wood board.
