Does Composite Decking Get Hot?
The comfort of outdoor decks is one of homeowners’ top concerns. In recent years, composite decking has grown increasingly popular. However, a common worry persists: Does composite decking get hot? Yes, composite decking board heats up under sunlight. Its temperature is influenced by color, density, and environmental factors. While it does warm up, modern technological designs enhance its heat resistance.
This paper will discuss the thermal characteristics of composite decking. It will analyze the key factors influencing its temperature. We will also give you specific steps to take to cool down composite decks. You can make your outdoor living area really comfortable and cool.

Does Composite Decking Get Hot in The Sun?
Yes. In full sunlight, any outdoor surface will soak up heat and get warmer. This includes wood, stone, plastic, and composite decking. This is an irreversible effect of nature. Because of this, composite deck boards will get very hot in the summer.
In sunlight places, the surface of a composite deck board can get 35 to 76 degrees Fahrenheit warmer than the air around it. Fortunately, composite decking offers excellent weather resistance and fade resistance. It won’t fade or age faster than it should, even if it’s exposed to heat for a long time. However, hot deck surfaces can make things less fun for users. There are several ways to deal with this problem.
Can Composite Decking Get Too Hot to Walk On?
Older composite decking heats up quickly, making it feel very hot to walk on. However, recent advancements in composite materials have significantly reduced this heating rate. Nevertheless, in certain extreme conditions, even modern composite decks can become extremely hot. Generally speaking, walking on the deck with shoes and socks on should be fine. However, we recommend extra caution for children or individuals with sensitive feet.
Is Composite Decking Hotter than Other Materials?
What is the best decking material for full sun? This takes into account how the homeowner uses it and for what purpose. To find the best decking material for full sun, you must carefully compare each decking material.
Composite vs. Wood
Does composite decking get hotter than wood? Professional tests have shown that unstained or lightly stained wood is cooler in hot weather. However, the temperature of wood also varies depending on the density of the wood itself.
The difference between stained and painted wood decks and composite decks is not as pronounced, though. On average, wood decks will be slightly cooler. However, the color of the deck can have a significant effect on the temperature.
Composite vs. PVC Decking
Since both types of decks contain plastic, the temperature difference between the two materials is not that significant. Again, the color of the deck directly affects the temperature of the deck, with light grey decking generally being cooler.
Composite vs. Concrete
Concrete has the highest temperature among all decking materials. Its temperature can easily exceed the maximum temperature of composite materials.
Core Factors Affecting Composite Deck Temperature
No one thing determines the end temperature of composite wood decking. It is affected by color, density, and the world as a whole.
Composite Deck Color
Color has the most clear and important effect on deck temperature. Dark areas take in more heat and light energy. When exposed to the same amount of sunshine, dark composite decking will have a much higher surface temperature than light-colored decking. The temperature change can be 20 to 30 degrees Fahrenheit or even more. Even though they look current and classy, they might make you feel uncomfortable in the summer.
Light-colored decking effectively reflects most sunlight, significantly reducing heat absorption. So, one of the easiest and most effective ways to cool down the deck surface is to choose choices that are light in color.
Direct Sunlight
The more direct sunlight a deck receives, the hotter the deck will get. So this makes sunlight a double-edged sword for decks. Many homeowners love a sunny outdoor deck, which is a cozy way to live outdoors. Great for relaxing and planting flowers, but it can also make composite decking get hot. In addition to making composite material hot, prolonged sunlight exposure can also damage your deck. For traditional wood decks, prolonged direct sunlight can cause severe cracking and warping of the deck.
Density and Structure
The temperature of composite wood decking is affected by its structure and density in a big way. The density of solid composite decking is higher. It stays hot for longer and cools down more slowly after soaking up heat.
On the other hand, hollow composite decking is made to be empty or porous. This structure makes a space inside for air that successfully stops heat from moving and building up. Because of this, hollow composite deck materials stay cooler on the surface in direct sunlight and cool down more quickly.
Environmental Factors
The air temperature surrounding the deck affects the deck’s own temperature. In extremely hot weather, the deck will naturally be hotter than in cooler conditions. Additionally, air circulation beneath the deck is crucial. Adequate airflow helps dissipate heat, allowing the deck to cool naturally. Conversely, decks with poor ventilation trap heat, causing temperatures to rise.
How to Keep Composite Decks Cool?
The steps below can help you make a cool composite deck space even in places with a lot of direct sunlight.
Selecting Appropriate Deck Colors and Types
If it gets hot in your area in the summer, light gray, light brown, or beige should be high on your list of deck colors when you are planning. When making a purchase, ask the seller if the item has an empty or porous structure. These kinds of products usually have better insulation features. Manufacturers such as Trex and EVODEK offer composite decking in a variety of colors and styles.
Adding Shade Structures
If you already have a deck, you might want to add shade structures. For example, composite pergolas look good and provide shade over a large area, so they are a good investment for the long run. You could also use protection sails or awnings. These can be put up in a number of different ways and come in many colors. You can move and change the size of the dark area as needed. At the same time, this is the most flexible and cost-effective option.
Improve Ventilation and Layout
During construction, ensure sufficient space between the deck underside and the ground. Maintain free airflow to dissipate heat. If possible, position the deck in an area shaded by buildings or trees. You can also place large potted plants around the deck perimeter. Some homeowners plant climbing vines to cover pergolas. These plants significantly lower ambient temperatures.
Cooling the Deck
If your composite deck becomes excessively hot, try these cooling methods before use:
- Use Outdoor Rugs: This provides an immediate solution. Laying outdoor rugs in activity and seating areas instantly creates a cooler space underfoot. Avoid using rubber-backed mats to prevent moisture buildup and mold growth.
- Spray With Water: Before use, spray the deck surface with water from a garden hose. Evaporation rapidly draws away significant heat. This method is simple and effective, though its cooling effect is short-lived.
Conclusion
Composite deck material does indeed heat up in the sun. This is a common characteristic of all outdoor decking materials. Modern composite decking is resistant to fading and aging caused by hot climates. You can keep loving being outside even in the hottest summer months by choosing the right colors and adding shade structures. If you have further questions about composite decking, please contact us.

FAQ
Is Composite Decking Hotter than Wood Decking?
Not necessarily. The primary factor affecting deck temperature is color, not material type. A light gray composite deck board typically stays much cooler than a dark wood deck.
Is Composite Decking Safe for Pets?
Composite wood decking is very safe for pets. It resists cracking, so it won’t scratch your pets. But if it’s really hot outside and the deck is in full sunlight, the surface can get too hot and hurt your pet’s paws. Providing a shaded outdoor rug or cooling mat can greatly enhance your pet’s comfort.
What Should I Consider When Installing Outdoor Rugs?
When using rugs on decking, ensure moisture doesn’t accumulate long-term. Opt for outdoor rugs designed with breathable backing. Regularly lift the rug to clean beneath it and the deck surface. This prevents mold and mildew growth. Avoid using completely non-breathable rubber mats.
