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. |
