SUNCOMFORTABLE™ HEAT-MITIGATING* TECHNOLOGY With SunComfortable™ Technology, we’ve achieved a major innovation, reducing heat buildup by up to 35°F† compared to our original boards.

*Trex SunComfortable™ decking stays cooler than our original boards, but like all decking, it will get hot in direct sun on hot days, especially darker colors. Care should be taken to avoid extended contact between exposed skin and the deck surface, especially with young children and those with special needs.​

Consider 2x6 boards for higher pound per foot applications.

†Based on laboratory testing simulating direct full summer sun exposure over an extended period. Colors used are Lava Rock (without SunComfortable) and Salt Flat (with SunComfortable). Actual temperature reduction may vary depending on environmental conditions, color and usage. Trex decking with SunComfortable tech- nology will still get hot when high temperatures and sun converge. Care should be taken on such days to avoid extended contact between exposed skin and the deck surface.
