System And Method For Installing Building Vapor Barrier

Abstract

A method and system for coupling a sealing vapor barrier to an internal surface of the building is presented. The method and systems utilize a flange disposed adjacent to a roof/wall interface to facilitate the movement of a first portion of the vapor barrier from adjacent to a wall frame to adjacent to a roof frame.

1 . A method for coupling a sealing vapor barrier to an internal surface of the building comprising:
 providing a flange disposed adjacent to a roof/wall interface;   coupling a flexible member to the sealing vapor barrier;   passing a portion of the flexible member over the flange;   passing the portion of the flexible member over a pulley disposed at a center roof rail;   pulling the flexible member over the flange and the pulley moving a first portion of the vapor barrier from a first location adjacent to a wall frame over the flange to a second position adjacent to a roof frame; and   sealable coupling the vapor barrier to the internal surface of the wall portion and the roof portion.   
     
     
         2 . The method according to  claim 1  further comprising coupling a second member between the vapor barrier and a flexible member, wherein the second member functions to maintain the shape of the vapor barrier during movement of the first portion of the vapor barrier from adjacent to a wall frame over the flange to the second position adjacent to a roof frame. 
     
     
         3 . The method according to  claim 1  further comprising sealably coupling the vapor barrier to a vertical wall support structure. 
     
     
         4 . (canceled) 
     
     
         5 . The method according to  claim 1  further comprising placing a plurality of first straps configured to couple the vapor barrier to the wall structure. 
     
     
         6 . The method according to  claim 5  further comprising positioning a second plurality of straps adjacent the vapor barrier to couple the vapor barrier to the roof. 
     
     
         7 . The method according to  claim 1  further comprising disposing insulation between the vapor barrier and the wall. 
     
     
         8 . The method according to  claim 1  wherein the internal surface of the building is a surface on an insulating material.
