Claims12
A thermoplastic roofing membrane comprising:
- a planar thermoplastic sheet, optionally having more than one layer, where at least one layer of the membrane includes an ethylene-based olefinic block copolymer, and where the sheet is characterized by a storage modulus of less than 450 MPa at 0° C.
A roof system comprising:
- a substrate and thermoplastic membrane adhered to the substrate, where the thermoplastic membrane includes one or more layers that include an ethylene-based olefinic block copolymer, where the membrane is characterized, prior to being adhered to the substrate, by a storage modulus of less than 450 MPa at 0° C.
