Abstract

A large-width, single-ply temporary membrane comprising a sheet of a linear low density polyetheylene (LLDPE) having a modulus of elasticity of at least 4 megapascals and a stretch percentage of at least 5%, wherein said sheet is self-adhering with a tensile adhesion strength of at least 1 psi when adhered to itself, and wherein said sheet is water impermeable and ultraviolet (UV) light resistant.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A large-width, single-ply temporary membrane for a roof comprising:
 a sheet of a linear low density polyetheylene (LLDPE) having a modulus of elasticity of at least 4 megapascals and a stretch percentage of at least 5%;   wherein said sheet is self-adhering with a tensile adhesion strength of at least 1 psi when adhered to itself; and   wherein said sheet is water impermeable and ultraviolet (UV) light resistant.   
     
     
         2 . The membrane of  claim 1 , wherein said membrane has a thickness of 12 mils. 
     
     
         3 . The membrane of  claim 1 , wherein said membrane has a coefficient of friction of 0.4. 
     
     
         4 . The membrane of  claim 1 , wherein said membrane as a tear strength of at least 220 grams force per mil. 
     
     
         5 . The membrane of  claim 1 , wherein said membrane as a tensile strength of at least 3100 psi. 
     
     
         6 . The membrane of  claim 1 , wherein said membrane as a dart impact strength of at least 3100 psi. 
     
     
         7 . The membrane of  claim 1 , wherein said membrane is ultraviolet (UV) light resistant for at least 24 months. 
     
     
         8 . The membrane of  claim 1 , wherein said membrane is flame retardant. 
     
     
         9 . The membrane of  claim 1 , wherein said sheet is at least 4 feet wide. 
     
     
         10 . The membrane of  claim 1 , wherein said sheet is configured to securely attach to an adhesive. 
     
     
         11 . A large-width, single-ply temporary membrane for a roof comprising:
 a sheet of a linear low density polyetheylene (LLDPE) having a modulus of elasticity of at least 4 megapascals and a stretch percentage of at least 5%;   wherein said sheet is self-adhering with a tensile adhesion strength of at least 1 psi when adhered to itself; and   wherein said sheet is water impermeable, ultraviolet (UV) light resistant and has a Flame Spread Index of 0.   
     
     
         12 . The membrane of  claim 11 , wherein said membrane has a thickness of 12 mils. 
     
     
         13 . The membrane of  claim 11 , wherein said membrane has a coefficient of friction of 0.4. 
     
     
         14 . The membrane of  claim 11 , wherein said membrane as a tear strength of at least 220 grams force per mil. 
     
     
         15 . The membrane of  claim 11 , wherein said membrane as a tensile strength of at least 3100 psi. 
     
     
         16 . The membrane of  claim 11 , wherein said membrane as a dart impact strength of at least 3100 psi. 
     
     
         17 . The membrane of  claim 11 , wherein said membrane is ultraviolet (UV) light resistant for at least 24 months. 
     
     
         18 . The membrane of  claim 11 , wherein said sheet is at least 4 feet wide. 
     
     
         19 . The membrane of  claim 11 , wherein said sheet is configured to securely attach to an adhesive.
