Barrier tape for seaming and repair of barrier sheets

Abstract

A barrier tape comprises a barrier section comprising one or more barrier layers and one or more adhesive layers adhered to a face of the barrier section. The barrier tape can be used to join together adjacent barrier sheets or to patch a breach in a barrier sheet to form a barrier assembly.

         3 . The barrier tape of  claim 1 , wherein the barrier section comprises one or more polar layers and one or more non-polar layers. 
     
     
         4 . The barrier tape of  claim 3 , wherein each of the one or more non-polar layers comprises a polyolefin and each of the one or more polar layers comprises ethylene vinyl alcohol. 
     
     
         5 . The barrier tape of claim wherein the barrier section comprises:
 one or more inner polar layers each formed predominantly from ethylene vinyl alcohol;   a pair of outer non-polar layers each formed predominantly from polyethylene, wherein a first of the pair of outer non-polar layers is positioned on a first side of the one or more inner polar layers and a second of the pair of outer non-polar layers is positioned on a second side of the one or more inner polar layers; and   a pair of tie layers each formed predominantly from polyethylene grafted with maleic anhydride, each of the pair of tie layers being positioned between the one or more inner polar layers and a corresponding one of the pair of outer non-polar layers.   
     
     
         6 . A barrier assembly comprising:
 a first barrier sheet;   a second barrier sheet overlapping the first barrier sheet along a seam; and   one or more pieces of barrier tape joining the first and second barrier sheets along the seam, each piece of the barrier tape comprising:
 a barrier section comprising one or more barrier layers; and 
 one or more adhesive layers adhered to a face of the barrier section. 
   
     
     
         7 . The barrier assembly of  claim 6 , wherein the seam is a lateral seam and wherein the second barrier sheet overlaps the first barrier sheet along the lateral seam, and wherein the one or more pieces of barrier tape join the first and second barrier sheets along the lateral seam. 
     
     
         8 . The barrier assembly of  claim 6 , wherein the first barrier sheet comprises a breach therethrough and the second barrier sheet comprises a barrier sheet patch covering the breach such that the seam substantially surrounds the breach, wherein the one or more pieces of barrier tape joint the barrier sheet patch to the first barrier sheet around the seam. 
     
     
         9 . The barrier assembly of  claim 6 , wherein the barrier section of each of the one or more pieces of barrier tape and each of the first and second barrier sheets provides a barrier to water vapor and at least one of methane, radon, and volatile organic compounds. 
     
     
         10 . The barrier assembly of  claim 6 , wherein the barrier section of each of the one or more pieces of the barrier tape comprises one or more polar tape layers and one or more non-polar tape layers. 
     
     
         11 . The barrier assembly of  claim 10 , wherein each of the one or more non-polar tape layers comprises a polyolefin and each of the one or more polar tape layers comprises ethylene vinyl alcohol. 
     
     
         12 . The barrier assembly of  claim 6 , wherein the barrier section of each of the one or more pieces of the barrier tape comprises:
 one or more inner polar tape layers each formed predominantly from ethylene vinyl alcohol;   a pair of outer non-polar tape layers each formed predominantly from polyethylene, wherein a first of the pair of outer non-polar tape layers is positioned on a first side of the one or more inner polar tape layers and a second of the pair of outer non-polar tape layers is positioned on a second side of the one or more inner polar tape layers; and   a pair of tape tie layers each formed predominantly from polyethylene grafted with maleic anhydride, each of the pair of tape tie layers being positioned between the one or more inner polar tape layers and a corresponding one of the pair of outer non-polar tape layers.   
     
     
         13 . The barrier assembly of  claim 6 , wherein each of the first and second barrier sheets comprises one or more polar sheet layers and one or more non-polar sheet layers. 
     
     
         14 . The barrier assembly of  claim 13 , wherein each of the one or more non-polar sheet layers comprises a polyolefin and each of the one or more polar sheet layers comprises ethylene vinyl alcohol. 
     
     
         15 . The barrier assembly of  claim 6 , wherein each of the first and second barrier sheets comprises:
 one or more inner polar sheet layers each formed predominantly from ethylene vinyl alcohol;   a pair of outer non-polar sheet layers each formed predominantly from polyethylene, wherein a first of the pair of outer non-polar sheet layers is positioned on a first side of the one or more inner polar sheet layers and a second of the pair of outer non-polar sheet layers is positioned on a second side of the one or more inner polar sheet layers; and   a pair of film tie layers each formed predominantly from polyethylene grafted with maleic anhydride, each of the pair of film tie layers being positioned between the one or more inner polar sheet layers and a corresponding one of the pair of outer non-polar sheet layers.
