As homeowners increasingly seek comfort, durability, and aesthetic appeal in their outdoor spaces, one common concern consistently arises: how hot will the deck get under direct sunlight? In sun-drenched regions, heat retention can make traditional decking uncomfortable—sometimes even dangerous—to walk on. That’s why more people are searching for composite decking that doesn’t get hot.

In this detailed guide, we’ll explore the best types of decking materials that stay cool underfoot, why some decking gets hotter than others, and which composite options you should consider for a more pleasant and usable outdoor living area.
Why Decking Temperature Matters
Whether you’re planning a backyard barbecue, setting up a poolside lounge, or building a tranquil outdoor escape, comfort underfoot is essential. Imagine stepping out barefoot on a hot summer day only to be met with scorching deck boards. That’s not just unpleasant—it can be a safety hazard, especially for children and pets.
This growing issue has prompted many homeowners and architects to prioritize decking that doesn’t get hot. Traditional wood, dark-stained surfaces, and some synthetic materials tend to absorb and retain heat. As a result, a deck can reach temperatures well above the surrounding air, making it practically unusable during peak sun hours.
What Makes Some Decking Get Hotter Than Others?
Several factors affect how hot a decking surface will become:
1. Material Composition
Natural woods tend to retain more heat than certain composites. However, not all composite decking is made equal. Some are engineered specifically to reflect sunlight and dissipate heat more effectively.
2. Color of the Decking
Dark colors absorb more heat. A dark brown or black deck will be significantly hotter than a light grey or beige one. Therefore, if heat is a concern, choosing a lighter-colored decking material that doesn’t get hot can help.
3. Surface Texture
Smooth, solid surfaces absorb and retain more heat than grooved or textured ones. A wood-grain texture or brushed finish can reflect sunlight better, reducing surface temperature.
4. Environmental Conditions
Location, wind, shade, and humidity can all influence how hot your decking feels. Even the orientation of your deck (north-facing or south-facing) plays a role.
The Rise of Composite Decking
Composite decking has gained enormous popularity as a low-maintenance, long-lasting alternative to traditional wood. Made from a blend of recycled plastic and wood fibers, it resists rot, splintering, and insect damage. However, early versions of composite decking were notorious for retaining heat.
Today, advanced manufacturing techniques and heat-reflective technology have transformed the game, allowing manufacturers to create composite decking that doesn’t get hot, even under direct sun exposure.
Benefits of Composite Decking That Doesn’t Get Hot
Let’s take a closer look at why this new generation of cooler composite decking is worth your investment:
1. Enhanced Comfort
No more jumping from foot to foot on a sizzling deck. With temperature-moderating properties, you and your guests can walk barefoot without discomfort.
2. Safer for Children and Pets
Sensitive paws and feet can be burned on hot surfaces. A cooler composite deck reduces the risk of burns and injury.
3. Increased Usability
Your deck becomes an extension of your home—usable during more hours of the day, even in the height of summer.
4. Aesthetic Versatility
Modern composite decking comes in a wide array of colors, textures, and finishes—many of which are designed to reflect rather than absorb sunlight.
5. Low Maintenance
Unlike wood, composite decking doesn’t require staining, sealing, or sanding to maintain its heat-reflective properties. It looks great with minimal upkeep.
Comparing Composite Decking That Doesn’t Get Hot: Which Material Performs Best?
When searching for composite decking that doesn’t get hot, homeowners are often faced with multiple options — from standard composite blends to new-generation capped composite boards with enhanced cooling technology. Not all composite materials are created equal when it comes to heat retention. To help you understand which decking performs best in hot climates, here’s a comparison of popular decking materials and their average surface temperatures under direct sunlight.
| Decking Material | Average Surface Temp (°F) | Heat Resistance | Cooling Technology |
|---|---|---|---|
| Traditional Composite Decking | 150 – 160 | ★★☆☆☆ | No |
| Capped Composite (Light Color) | 130 – 140 | ★★★★☆ | Yes (reflective additives) |
| PVC Decking | 125 – 135 | ★★★★★ | Yes (cool pigment tech) |
| Wood (Cedar/Redwood) | 120 – 130 | ★★★☆☆ | Natural insulation |
| Aluminum Decking | 105 – 115 | ★★★★★ | High reflectivity |
As the table shows, composite decking that doesn’t get hot usually belongs to the newer capped or PVC categories, especially when you choose lighter shades. These materials integrate UV-blocking layers or cool pigment technologies to reflect sunlight and reduce thermal buildup. While traditional composites may retain more heat, innovative manufacturers have responded to climate demands by developing alternatives that stay comfortable even in peak summer sun. When choosing a decking material that doesn’t get hot, look beyond appearance — pay attention to the material technology and color as they directly influence comfort underfoot.
Best Features to Look for in Cooler Composite Decking
Not all composite decking brands offer composite decking that doesn’t get hot, so it’s important to know what features to look for:
Light color tones: Choose white, light grey, or sandy hues to reduce heat absorption.
Hollow core design: Some composite boards are engineered with hollow cores, which improve airflow and minimize heat buildup.
Reflective pigments: Innovative technologies use UV-reflective pigments that prevent the boards from overheating.
Matte or textured finish: These reduce surface contact with sun rays and feel cooler underfoot.

Where You Might Need Cooler Decking the Most
Certain environments and deck designs demand materials that remain cool:
– Poolside Decking
Barefoot use is common, and reflected sunlight off the water amplifies heat. Composite decking with temperature regulation is ideal.
– Rooftop Decks
Little to no shade means direct sun exposure all day long. Lighter-colored composite boards are essential.
– Play Areas for Kids
Children are sensitive to hot surfaces. Cooler decking prevents discomfort and burns during playtime.
– Outdoor Dining and Cooking Spaces
Comfort is key when entertaining guests. Decking that doesn’t get hot keeps everyone happy and safe.
Design Tips for a Cooler Deck
Even if you’ve selected composite decking that doesn’t get hot, you can enhance comfort by incorporating smart design elements:
Use Shade Structures: Pergolas, umbrellas, or shade sails can reduce direct sunlight exposure.
Add Outdoor Rugs: These not only provide a cooler surface to walk on but also elevate the deck’s style.
Plant Trees or Shrubs: Natural shade sources cool down the surrounding environment and improve aesthetics.
Install Mist Cooling Systems: For extreme climates, a mist system can help keep both the air and surface temperatures lower.
Common Myths About Composite Decking and Heat
Myth 1: All composite decking gets too hot.
False. While older generations did retain heat, today’s advanced composite decking options are engineered to reflect heat and stay cool underfoot.
Myth 2: Only wood stays cool.
Also false. Wood absorbs and retains heat, often more than modern PVC or capped polymer decking boards designed for thermal performance.
Myth 3: You can’t have a dark deck if you want it to stay cool.
Not entirely true. Some manufacturers have introduced dark-colored boards with heat-reflective pigments, although lighter shades are still preferable for maximum comfort.
Conclusion: Choose Comfort with Composite Decking That Doesn’t Get Hot
