What decking stays the coolest?

In general, lighter-colored decking materials tend to stay cooler than darker-colored ones. This is because lighter colors reflect more sunlight and absorb less heat. However, it’s important to note that all decking materials will absorb some amount of heat when exposed to direct sunlight.

Some decking options that are known to have good heat resistance and stay relatively cool underfoot include:

  1. PVC (Polyvinyl Chloride) Decking: PVC decking has a high heat resistance and tends to stay cooler compared to other decking materials. It doesn’t absorb much heat and dissipates it quickly.
  1. Composite Decking with Cooling Technology: Some composite decking brands offer products with built-in cooling technology. These decks are designed to reflect more sunlight and have enhanced heat dissipation properties.
  1. Timber Decking with Light Colors: Light-colored timber decking, such as pine or light-colored hardwoods, can be cooler than darker timber options. Lighter colors reflect more heat and minimize heat absorption.

It’s worth noting that regardless of the decking material, direct sunlight and hot ambient temperatures can still cause the surface of the deck to become warm. Using shading elements like umbrellas or pergolas, and incorporating proper ventilation in the deck design can help reduce heat buildup. Additionally, regular cleaning and maintenance can also contribute to keeping the deck cooler by preventing the buildup of debris and dirt that can retain heat.
