Abstract
One exemplary embodiment is directed to a thermoplastic-based building product having a front face with a length and a width, an opposing back face, opposing top and bottom edges each with a thickness. The building product comprises at least one thermoplastic-based support layer, and at least one reinforcing flexing layer having a coefficient of linear thermal expansion (CLTE) of less than or equal to about 15 ppm/° C. over the temperature range of −20° C. to 70° C. The at least one reinforcing flexing layer is at least partially embedded in the at least one thermoplastic-based support layer along a longitudinal axis of the building product.
Claims22
A thermoplastic-based building product having a front face with a length and a width, an opposing back face, opposing top and bottom edges each with a thickness, the building product comprising:
- at least one thermoplastic-based support layer;
- and
- at least one reinforcing flexing layer having a coefficient of linear thermal expansion (CLTE) of less than or equal to about 15 ppm/° C. over the temperature range of −20° C. to 70° C., wherein the at least one reinforcing flexing layer is at least partially embedded in the at least one thermoplastic-based support layer along a longitudinal axis of the building product.
A thermoplastic-based building product having a front face with a length and a width, an opposing back face, opposing top and bottom edges each with a thickness, the building product comprising:
- at least one thermoplastic-based support layer comprising a thermoplastic polymer selected from at least one of polyvinyl chloride, polyethylene, polypropylene, and combinations thereof;
- and
- at least one reinforcing flexing layer comprising a fiberglass impregnated tape containing unidirectional continuous fiberglass fibers, wherein the at least one reinforcing flexing layer is embedded substantially in the center of the at least one thermoplastic-based support layer along a longitudinal axis of the building product, wherein the at least one reinforcing flexing layer has a coefficient of linear thermal expansion (CLTE) of less than or equal to about 15 ppm/° C. over the temperature range of −20° C. to 70° C.,
- wherein the building product has a coefficient of thermal expansion of about 7 to about 45 ppm/° C. over the temperature range of −20° C. to 70° C.
