Abstract:
A co-extruded structural member is disclosed having first and second co-extruded layers. The first co-extruded substrate layer comprises a structural preform and is substantially reflective of near-infrared (near-IR) radiation. A co-extruded cap layer is substantially transparent to near-IR radiation. The cap layer can be provided in aesthetically pleasing dark colors, while heat absorption is minimized due to the reflective properties of the near-IR reflective substrate layer. Using a co-extrusion process enhances the durability of the ultimate product over previous systems which use relatively fragile paint coatings to limit heat absorption. By providing near-IR transmissive and reflective pigments within the co-extruded polymers, a highly durable finished product is obtained. The co-extruded layers are disclosed for use in fence and deck applications, but will also find application in a wide variety of building product applications, both exterior and interior.
