Does Composite Decking Get Hot?
Composite decking has become an increasingly popular choice for homeowners in the UK due to its durability, aesthetics, and low maintenance. However, one common concern is “Does composite decking get hot?” especially during the summer months. Understanding how composite decking retains heat, how it compares to other materials, and what factors influence its temperature can help homeowners make informed decisions. In this blog, we will explore how composite decking handles heat, particularly in the UK climate, and provide practical solutions for keeping decking cool.

How Does Heat Retention in Composite Decking Work
Like any outdoor surface, composite decking absorbs heat when exposed to direct sunlight. The extent to which it heats up depends on the materials used in its composition. Composite decking is typically made from a blend of recycled wood fibres and plastic, which can retain more heat than natural wood but generally less than fully synthetic materials like PVC.
Several factors influence the heat retention of composite decking, including:
- Material composition: The mix of wood and plastic affects heat absorption levels.
- Colour choice: Darker colours absorb more heat than lighter shades.
- Exposure to direct sunlight: Shaded areas tend to stay cooler than those in full sun.
- Ventilation and airflow: Good airflow around the decking can help dissipate heat.
- Surface texture: Grooved or embossed surfaces can feel cooler underfoot compared to smooth, flat surfaces.

How Does Composite Decking Get Hot Compared to Other Materials
When considering outdoor flooring options and the question “Does composite decking get hot?”, it is useful to compare composite decking to alternative materials in terms of heat retention:
- Natural wood: While wood absorbs less heat than composite, it can still become uncomfortably warm in direct sunlight. However, it does cool down more quickly once shaded.
- PVC decking: Fully synthetic materials like PVC tend to absorb and retain more heat than composite decking, making them hotter underfoot.
- Stone or concrete paving: These materials absorb significant heat and can become extremely hot in the sun, often retaining warmth for long periods.
Does composite decking get hot? Overall, composite decking tends to be warmer than wood but cooler than PVC, making it a balanced choice for those concerned about heat retention.
Does Composite Decking Get Hot in Different Conditions?
Several environmental conditions influence how hot composite decking can get:
- Does composite decking get hot in the sun? Yes, composite decking can become warm when exposed to direct sunlight, but the extent depends on the material, colour, and location.
- Does composite decking get hot in the summer? During summer, prolonged sun exposure can raise the surface temperature, but this is comparable to other outdoor flooring materials.
- Does composite decking get hot in the UK? The UK’s moderate climate means that composite decking does not reach extreme temperatures as it might in hotter countries. However, during heatwaves, it may become much warmer than expected.

Ways to Keep Composite Decking Cool
While composite decking can get warm, there are several ways to reduce heat retention and enhance the comfort of those using the space:
- Choose the Right Colour and Finish: Lighter colours reflect more sunlight, making them cooler. Matt finishes tend to absorb less heat than glossy surfaces.
- Install Shading Structures: Pergolas, awnings, or umbrellas provide shade and lower the surface temperature. Planting trees or tall shrubs can offer natural cooling with their shade.
- Use Cooling Solutions: Outdoor rugs or artificial grass sections help create cooler walkways. Misting systems or sprinklers can temporarily lower the decking temperature. Allow airflow underneath the decking by using raised or ventilated designs.
- Schedule Usage Wisely: Using decking in the morning or evening rather than peak midday hours can improve comfort levels.

Frequently Asked Questions
1. How Hot Does Composite Decking Get?
The temperature of composite decking varies based on external conditions and product design and these influence the answer to the question “Does composite decking get hot?”. Key factors influencing heat build-up include:
- Time of day: Decking exposed to peak midday sun will be warmer than shaded decking. Install a misting system or use light-coloured outdoor rugs to keep the surface cooler.
- Geographical location: Southern parts of the UK may experience slightly higher surface temperatures.
- Surface colour: Lighter shades reflect more sunlight and remain cooler than darker options. Choose lighter grey or beige composite decking to reduce heat absorption.
- Surrounding structures: Buildings, trees, or pergolas can provide shade and reduce heat absorption. Place shaded structures over high-exposure areas.

2. Does Dark Composite Decking Get Hotter?
Yes, darker composite decking absorbs more sunlight than lighter-coloured decking, making it hotter underfoot. Homeowners who prefer darker shades should think about implementing other measures to try and lessen the heat of their dark decking.
3. Does Composite Decking Get Hot to Walk On?
Does composite decking get hot? One of the most common concerns for homeowners is whether composite decking gets too hot to walk on barefoot. While composite decking does absorb heat, it can remain comfortable for foot traffic, especially if installed in shaded or partially shaded areas.
4. Does Composite Decking Melt?
Composite decking is designed to withstand high temperatures without melting under normal conditions. However, in extreme heat scenarios, such as direct exposure to fire or an intense heat source like a barbecue placed too close to the surface, damage may occur. EnviroBuild’s composite decking has a high heat resistance and does not warp or melt under typical UK summer conditions if it is installed correctly.
To prevent heat damage:
- Avoid placing hot objects, such as fire pits or barbecues, directly on the decking.
- Use a heat-resistant mat under grills or outdoor heaters.
- Ensure proper ventilation to avoid heat build-up in enclosed spaces.
