Compositions and methods for reducing the surface temperature of composite articles

An article comprising:

• (a) a wood plastic composite core having a peripheral surface;
• and
• (b) a capstock bonded to at least a portion of the peripheral surface of the wood plastic composite core, wherein the capstock comprises a polymer matrix with an infrared reflective additive blended therein, the infrared reflective additive comprising one or more infrared reflective colorants and a thermally emissive filler;
• wherein:
• the capstock has an L* value according to CIE L*a*b* color scale coordinates of less than 50;
• and
• the capstock has a heat build-up according to HBU (OIR) of less than 60° F. and/or a heat build-up according to HBU ASTM-D4803 of less than 60° F.
