Heat-Mitigating Decking: The Future of Comfortable Outdoor Living

Decking That Raises the Bar—Not the Temperature

When you think of perfect outdoor spaces—a place to relax, entertain, or enjoy the beauty of nature—comfort is key. Step onto a deck that redefines outdoor living. With Trex SunComfortable™ Technology, you can enjoy cooler* decking—even on the sunniest days.

What is SunComfortable™ Technology?

Trex SunComfortable™ Technology redefines what performance looks like in the heat. Our heat-mitigating decking is engineered to reflect solar energy and reduce heat absorption, keeping deck surfaces cooler.

With SunComfortable, we’ve achieved a major innovation—reducing heat buildup by up to 37 degrees compared to our original boards**.

 

**Based on laboratory testing simulating full summer sun exposure at noon over an extended period. Actual temperature reduction may vary depending on environmental conditions, color and usage.

Choosing the Right Color to Keep Your Deck Cooler


Color plays a big role in how hot your deck gets in the sun. Light-colored boards like white, gray, or tan absorb less heat, keeping the surface cooler for sunny spaces. Darker colors like black or brown absorb more heat, making the surface hotter.

For those who love darker tones, Trex offers heat-mitigating options in rich grays and warm browns, using innovative cooling technology. If you're worried about heat, lighter tones like Salt Flat and Carmel are great choices that naturally stay cooler. With Trex, you get style and practicality, no matter the color.

View All FAQs
01
Is composite decking hot in the sun?

Just like many other outdoor walking surfaces, composite decking can get hot due to sun exposure or weather. On these hot days - care needs to be taken to make sure skin does not have extended contact with the surface of the deck. For hotter climates, we recommend choosing a lighter color or one of our Lineage deck boards. The Transcend Lineage line of decking is engineered with heat-mitigating technology to give you our coolest decking yet.* It offers a noticeably cooler board than any of our other decking collections.

02
Is Trex decking environmentally friendly?

Yes. Trex composite decking is sustainably made in the USA from up to 95% recycled plastic film and reclaimed wood.

03
What is the lifetime value of Trex?

With pressure-treated wood decks, maintenance costs add up over time. Although Trex costs more initially, you'll never have to sand, stain or paint your Trex deck. Over the life of your deck, those reduced maintenance costs add up to a greater value than wood—not to mention the value of the added time spent enjoying your deck rather than working on it. If you would like to see the difference in maintenance costs for your deck of wood vs composite, visit our Decking Comparison page.

What's more, Trex decking is made from 95% recycled materials: That's an eco-friendly decking choice you can feel great about. To learn more please review our Trex vs. Wood page.
