Understanding Composite Decking

Before we discuss whether composite decking gets hot, let’s understand what composite decking is and why it has gained popularity:


Composite decking is made from a blend of wood fibers, recycled plastics, and bonding agents. This combination results in a durable and low-maintenance decking material.


Composite decking offers several advantages, including resistance to rot, splintering, and insect damage. It doesn’t require staining or sealing, making it relatively low maintenance. Additionally, it comes in various colors and textures, allowing homeowners to customize their outdoor spaces.

Now, let’s address the burning question:

Does Composite Decking Get Hot? 🔥


Composite decking can become warm when exposed to direct sunlight, but it doesn’t get as hot as some other decking materials. Here’s why:

Color Matters

The color of your composite decking plays a significant role in how hot it gets. Darker-colored composite decking absorbs more heat than lighter-colored options. If you’re concerned about heat, consider choosing a lighter shade for your deck. Lighter colors can help reduce heat absorption and keep your deck more comfortable in the sun.

Heat Dissipation

Composite decking has good heat dissipation properties. Unlike some materials that retain heat, composite boards tend to cool down relatively quickly once the sun is no longer directly on them. This means you can enjoy your deck comfortably even on warm summer evenings.

Wood-Plastic Blend

The wood and plastic blend in composite decking helps regulate temperature. While the plastic component can heat up, the wood fibers help distribute and dissipate the heat, preventing the surface from becoming excessively hot. This balance between materials ensures a more comfortable experience when walking on your deck.

Heat Tolerance

Composite decking is designed to withstand various weather conditions, including heat. It won’t warp or become damaged due to moderate heat exposure. This durability ensures that your composite deck will remain in excellent condition even in hot climates or during heatwaves.

Comparing Composite Decking to Other Materials

To give you a better perspective on composite decking temperature, let’s compare it to 3 other common decking materials:

1. Wood Decking

🌡️ Temperature: Wood decking can become scorching hot when exposed to direct sunlight. Dark-colored wood decks, in particular, can be uncomfortable to walk on during hot days.

🔨 Maintenance: Wood decks require regular staining and sealing to maintain their appearance and protect against rot and decay.

👣 Comfort Level: Wood decking can be hot to the touch in summer, making it less comfortable for barefoot walking.

2. PVC Decking

🌡️ Temperature: PVC decking, like composite decking, can become warm in the sun but generally doesn’t get as hot as wood.

🔨 Maintenance: PVC decking is low-maintenance, requiring minimal upkeep beyond occasional cleaning.

👣 Comfort Level: PVC decking offers a comfortable surface to walk on, even in hot weather.

3. Concrete Patio

🌡️ Temperature: Concrete patios can absorb and retain a significant amount of heat, becoming extremely hot in direct sunlight.

🔨 Maintenance: Concrete patios are relatively low-maintenance but may require periodic sealing to prevent cracks.

👣 Comfort Level: Concrete can become too hot for comfortable barefoot use during hot summer days.

Tips for Keeping Your Composite Deck Cool


If you’re concerned about the temperature of your composite deck during hot weather, here are some tips to help keep it cool and comfortable:

  • Choose Lighter Colors: Opt for lighter-colored composite decking, which absorbs less heat than darker shades. Lighter colors can significantly contribute to a cooler deck surface during hot weather.
  • Shade and Umbrellas: Use patio umbrellas, pergolas, or shade sails to provide shade and reduce direct sunlight on your deck. These structures not only keep your deck cooler but also create a comfortable outdoor living space.
  • Outdoor Rugs: Lay down outdoor rugs or mats to create a cooler surface for walking and lounging. These rugs not only enhance comfort but also add a touch of style to your deck.
  • Ventilation: Ensure your deck has proper ventilation to allow hot air to escape, preventing heat buildup. Adequate airflow helps maintain a more pleasant temperature on your deck.
  • Cooling Products: Explore cooling products designed for outdoor use, such as cooling deck tiles or misting systems. These innovative solutions can significantly lower the temperature on your deck, making it enjoyable even on scorching days.
  • Time of Use: Use your deck during cooler parts of the day, such as mornings and evenings, to avoid the midday heat. Planning your outdoor activities during these times can make a significant difference in comfort during hot weather.

Stay Cool on Composite Decking

Composite decking is a practical and attractive choice for outdoor spaces, and it generally doesn’t get as hot as some other decking materials. While it can become warm in direct sunlight, it offers comfort and low maintenance compared to alternatives like wood or concrete. By selecting lighter-colored composite decking, incorporating shading solutions, and following our tips, you can enjoy your composite deck even on the hottest summer days. So go ahead, relax, and soak up the sun without worrying about burning your feet!
