Decking That Raises the Bar—Not the Temperature

When you think of perfect outdoor spaces, whether it’s for relaxing, entertaining, or enjoying the beauty of nature, comfort is key.

Step onto a deck that redefines outdoor living with Trex SunComfortable™ technology—more heat resistant than standard composite decking*.

*Although Trex decking products with SunComfortable heat-mitigating technology are designed to be cooler than most other composite decking products of a similar color, on a hot sunny day, they will get hot. On such days, care should be taken to avoid extended contact between exposed skin and the deck surface, especially with young children and those with special needs.

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* versus standard composite decking.

With SunComfortable decking, we’ve achieved a major innovation: reducing heat buildup by up to 35 degrees fahrenheit compared to our original boards^†.

Actual temperature reduction may vary depending on environmental conditions, color and usage. Trex decking with SunComfortable technology 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.}

Color + Climate: What to Know About Deck Temperatures

Like many other outdoor walking surfaces, composite decking can get hot due to sun exposure and hot weather. That’s why it’s important to consider your climate, sun exposure, and deck color when choosing your boards.

If your deck sits in direct sun all day, especially in hotter climates, you’ll notice more surface heat than someone in a cooler region or with partial shade. That’s true for all decking, regardless of material.

Trex gives you options with more heat-resistance across the color spectrum. Love a deeper hue? Explore rich browns and grays in our SunComfortable™ collection. They’re engineered to help reduce surface temperatures compared to similar colors without this technology.

Where SunComfortable™ Decking Works Best

Not all outdoor spaces experience the same conditions. Your deck’s exposure to sun and heat should play a major role in your material and color selection.

Here’s what we recommend, based on climate and how much sun your deck gets throughout the day:

1Hot Climates + Full Sun Exposure

If you live in a warmer region or have a deck that’s exposed to direct sunlight for most of the day, surface temperature becomes a key consideration.

Choose lighter colors that reflect more sunlight and retain less heat.
Recommended shades: Salt Flat, Carmel, and other light neutrals in the SunComfortable™ lineup.

2Moderate Climates + Partial Shade

If your deck gets some daily sun but benefits from tree cover, awnings, or architectural shade during peak hours, heat may be less of a concern—but still worth considering in warmer months.

You have flexibility here. Use SunComfortable™ for added performance in sunny spots, or go with traditional Trex decking; either option gives you style and durability.
Choose from a wider range of tones—from soft neutrals to deeper hues—based on your personal design goals.

Werden Terrassendielen aus Verbundmaterial in der Sonne heiß?

Wie viele andere Gehflächen im Freien können auch Verbundwerkstoff-Terrassen durch Sonneneinstrahlung oder Witterung heiß werden. An diesen heißen Tagen muss darauf geachtet werden, dass die Haut nicht zu lange mit der Oberfläche der Terrasse in Kontakt kommt. In wärmeren Klimazonen empfehlen wir, eine hellere Farbe oder eine unserer Lineage-Dielen zu wählen. Die Transcend Lineage Terrassendielen wurden mit einer hitzedämpfenden Technologie entwickelt, um Ihnen die bisher kühlsten Terrassendielen zu bieten * Sie sind spürbar kühler als alle anderen Terrassendielen.

Was ist der Lebenszeitwert von Trex?

Bei druckbehandelten Holzbelägen summieren sich die Pflegekosten im Laufe der Zeit. Obwohl Trex anfangs teurer ist, müssen Sie Ihre Trex-Terrasse nie schleifen, beizen oder lackieren. Über die gesamte Lebensdauer Ihrer Terrasse summieren sich diese reduzierten Wartungskosten zu einem höheren Wert als bei Holz - ganz zu schweigen von der zusätzlichen Zeit, die Sie damit verbringen, Ihre Terrasse zu genießen, anstatt an ihr zu arbeiten. Wenn Sie den Unterschied zwischen den Kosten für die Wartung Ihrer Terrasse aus Holz und Verbundmaterial sehen möchten, besuchen Sie unsere Vergleichsseite für Terrassendielen.

Warum sind Trex ® Terrassendielen besser als Holz?

Trex-Produkte bieten eine überragende Haltbarkeit und Leistung, die Sie mit Holz nicht erreichen können. Trex-Terrassendielen sind resistent gegen Termiten, verrotten nicht, verziehen sich nicht und splittern nicht - und müssen nie gebeizt oder gestrichen werden. Darüber hinaus besteht die Trex Terrassendielen zu 95 % aus recycelten Materialien: Das ist eine umweltfreundliche Terrassenbelagwahl , auf die Sie sich freuen können.
