Temporarily Adhered Mechanically Attached Weather Barrier Material

Abstract

Disclosed is a method of installing a flashing tape onto a building surface proximate to an opening in a building structure. The method includes: providing a roll of flexible flashing tape, wherein the flexible flashing tape comprises a flexible substrate with an adhesive layer on one surface of the flexible substrate, wherein the adhesive layer has sufficiently low adhesion such that the flashing tape may be easily unrolled without the need for a release liner and may be removably adhered to the building surface; unrolling a portion of the flexible flashing tape and positioning it onto the building surface such that the adhesive layer contacts the building surface and removably adheres the flashing tape to the building surface until the flashing tape can be permanently fastened thereto; and permanently fastening the flashing tape to the building surface with mechanical fasteners.

1 . A method of installing a weather barrier sheet onto a building surface of a building structure comprising:
 providing a roll of flexible weather barrier sheet, wherein the flexible weather barrier sheet comprises a flexible substrate with an adhesive layer on one surface of the flexible substrate, wherein the adhesive layer has sufficiently low adhesion such that the weather barrier sheet may be easily unrolled without the need for a removable release liner and may be removably adhered to the building surface;   unrolling a portion of the flexible weather barrier sheet and positioning it onto the building surface such that the adhesive layer contacts the building surface and removably adheres the weather barrier sheet to the building surface until the weather barrier sheet can be permanently fastened thereto; and   permanently fastening the weather barrier sheet to the building surface with mechanical fasteners.   
   
   
       2 . The method of  claim 1  wherein the adhesive layer is a continuous layer over the entire surface of the flexible substrate. 
   
   
       3 . The method of  claim 1  wherein the adhesive layer is a discontinuous layer. 
   
   
       4 . The method of  claim 3  wherein the adhesive layer is in a pattern selected from stripes, dots, blocks, triangles, diamonds, rectangles, ovals, circles, or a combination thereof. 
   
   
       5 . The method of  claim 1  wherein the flexible weather barrier sheet is repositioned onto the building surface as necessary prior to permanently fastening it. 
   
   
       6 . The method of  claim 1  wherein the mechanical fasteners are selected from staples, tacks and nails. 
   
   
       7 . The method of  claim 1  wherein the flexible weather barrier sheet is cut to an appropriate length either before or after positioning it onto the building surface. 
   
   
       8 . The method according to  claim 1  wherein the weather barrier sheet is a flashing tape and the building surface is proximate to an opening in a building structure. 
   
   
       9 . The method of  claim 8  wherein the flashing tape has a width of about 4 in. to about 12 in. 
   
   
       10 . The method of  claim 1  wherein the adhesive layer has sufficiently low adhesion such that it will adhere to the building surface with a force of less than 0.25 pli (pounds per linear inch).
