As the popularity of outdoor living continues to soar, homeowners are constantly looking for materials that offer durability, style, and comfort. One key consideration, especially in hot climates, is heat retention. Traditional decking materials can become uncomfortably hot under the sun, making them hard to walk on barefoot. This is where cool composite decking comes in—a game-changing solution that offers a blend of aesthetics, performance, and temperature control.

In this guide, we will delve deep into cool composite decking, exploring what makes it cooler than other options, the best cool touch composite decking brands, how to choose materials that stay cooler underfoot, and tips for keeping your deck comfortable even in peak summer heat.
What Do You Know About Cool Composite Decking?
Cool composite decking refers to composite decking boards that are designed or formulated to stay cooler than traditional materials under direct sunlight. While no outdoor decking is entirely immune to heat, certain technologies and materials significantly reduce surface temperatures. These innovations make composite decking that stays cool a top choice for patios, pool surrounds, and sun-drenched outdoor areas.
Composite decking itself is made from a mix of wood fibers and plastic—often recycled—which is processed into boards that mimic the appearance of wood while requiring far less maintenance. The coolest composite deck material goes a step further by incorporating light-reflective technology, heat-resistant coatings, or lighter pigments that don’t absorb as much solar heat.
Why Heat Matters: A Comfort and Safety Concern
If you’ve ever stepped barefoot on a hot wood or stone surface in mid-summer, you understand how painful it can be. Surface temperatures can exceed 150°F (65°C) on dark-colored decks, creating real discomfort and even burns. For families with kids, pets, or elderly members, a stay cool composite decking system offers both comfort and peace of mind.
Moreover, cooler decking materials reduce thermal expansion, making your deck more structurally stable over time.
How Composite Decking Can Stay Cool
So, how does cool composite decking manage to resist heat better than conventional decking options? It all comes down to a combination of several factors:
1. Color Selection
Lighter colors reflect more sunlight than darker ones, which helps maintain lower surface temperatures. Many cool touch composite decking collections now offer elegant, light-toned options like beige, light grey, sand, and soft oak.
2. Material Composition
Some brands use specific formulations of polymer and additives that have lower thermal conductivity, keeping boards cooler. A higher ratio of plastic to wood fibers also tends to retain less heat.
3. Capping Technology
Many premium boards feature a protective cap layer engineered to deflect sunlight. These caps often use advanced pigments or infrared-reflective technology.
4. Board Design
Hollow boards or boards with grooves can allow air circulation, further reducing heat retention compared to solid boards.
5. Installation Technique
The way your deck is built—spacing, ventilation underneath, and elevation—can also influence how hot the surface gets. Proper airflow beneath the decking can significantly reduce overall temperature.

Cool Composite Decking vs Other Materials
Let’s compare cool composite decking with other common decking materials to better understand its advantages.
| Material | Heat Retention | Maintenance | Aesthetic Variety | Durability |
|---|---|---|---|---|
| Pressure-treated wood | High | High | Moderate | Moderate |
| Hardwood (e.g., Ipe) | Very High | Medium | Natural look | Very High |
| PVC Decking | Low to Moderate | Low | High | High |
| Standard Composite | Moderate to High | Low | High | High |
| Cool Composite | Low | Low | Very High | Very High |
While hardwoods like Ipe may last decades, they get scorching hot and require regular sealing. PVC stays cool but lacks the eco-friendliness of composites. Cool composite decking offers a balanced approach
Tips to Keep Your Deck Cooler
Even with cool composite decking, there are practical steps you can take to enhance comfort:
1. Use Light-Colored Rugs or Mats
Outdoor rugs not only add style but also create a buffer between feet and the deck.
2. Install Shade Structures
Pergolas, umbrellas, or retractable awnings provide overhead protection and help keep surface temperatures lower.
3. Use Outdoor Misting Systems
Misting cools both the air and deck surface. Combine this with composite decking that stays cool for maximum comfort.
4. Consider Elevated Deck Designs
Decks with sufficient clearance from the ground allow airflow underneath, helping dissipate heat.
5. Plant Surrounding Vegetation
Shrubs, vines, or trees provide natural shade and contribute to a cooler microclimate around your deck.
Cool Composite Decking Around Pools
One of the best uses for cool composite decking is in pool areas. Wet feet and hot surfaces are a dangerous combination. Composite boards that resist both heat and moisture are ideal.
Cool deck composite decking offers anti-slip surfaces, splinter-free comfort, and low surface temperatures—all essential for poolside safety. Pair it with a UV-resistant finish, and your deck will look and feel great for years.
Best Colors for Stay Cool Composite Decking
Color plays a critical role in how much heat your decking absorbs. Here’s a list of the most popular cool touch composite decking colors:
Whitewashed Grey – Modern and reflective
Sandy Beige – Beachy vibes with low heat absorption
Driftwood – Natural aesthetics with practical temperature control
Light Oak – Classic and versatile
Avoid darker colors like deep brown, mahogany, or charcoal if staying cool is your priority.
Eco-Friendliness of Cool Composite Decking
Most cool composite decking boards are made from recycled materials, such as reclaimed wood and plastic bags. Choosing this kind of decking means you’re investing in a sustainable product that reduces landfill waste and deforestation.
Some brands even offer LEED credit opportunities for builders aiming for green certification.
Cost Considerations
Cooler composite decking tends to be on the premium end of the pricing spectrum due to the advanced technologies used. However, the long-term benefits—like reduced maintenance, increased comfort, and greater durability—often outweigh the upfront costs.
On average, you can expect to pay:
Standard composite: $5–$8 per sq. ft.
Cool composite decking: $7–$12 per sq. ft.
Always factor in accessories, fasteners, substructure, and labor costs when budgeting your project.
Maintenance and Longevity
Unlike natural wood, cool composite decking does not need painting, staining, or sealing. Maintenance typically involves occasional washing with mild soap and water.
Moreover, due to its reduced heat retention, there’s less thermal expansion and contraction, meaning fewer issues with warping or cracking over time.
With proper care, your deck can last 25 to 30 years or more.
Final Thoughts: Is Cool Composite Decking Right for You?
If you live in a hot climate, have sensitive feet, or simply want to maximize outdoor comfort, cool composite decking is one of the best investments you can make. It offers the perfect blend of:
Heat reduction
