With the rise in popularity of composite decking over recent years, it comes to no surprise that more and more homeowners are asking questions regarding its practicality, with one of the main queries surrounding its use in the warmer months. 

Homeowners that are considering installing composite decking in their outdoor spaces are asking the question, "does composite decking get hot in the summer?" With traditional wood decking known to absorb a fair amount of heat during hotter spells of sunshine, it makes perfect sense why people would ask the same question regarding its composite counterpart. If you're one of these people that are wondering whether composite decking gets hot in the summer, then you've come to the right place! The experts at TimberTech are here to help. 

In order to give an accurate answer to this question, however, a number of factors need to be considered as each has a degree of influence on how much heat gets absorbed and retained. These are the deck's exposure to sunlight, the colour of the deck boards and the type of composite decking used

Does Composite Decking Get Hot in the Summer?

Exposure to Sunlight 

All materials exposed to sunlight will absorb some degree of heat. That's a fact. Natural wood decking, however, can become too hot to walk on barefoot when it is exposed to the summer sun over a prolonged period of time. Not only that, once exposed to high temperatures, wood decking can also shrink, splinter and crack, posing bigger issues than just hot feet. Composite decking, on the other hand, can withstand such heat without the possibility of these additional hazards occurring. This is due to its state-of-the-art manufacture where highly reflective pigments are used to give composite deck boards their colour and fantastic heat-resistant properties.

When exposed to the sun, composite decking may warm slightly, but not enough to leave you searching for the closest pair of shoes or slippers! If this is something you'd rather avoid altogether, adding shade spots to your decking through canopies, carpets and cooling fans are great ways to ensure a cool walking surface regardless of the temperatures.  

 

Colour of the Deck Boards 

The next factor that influences how much heat composite decking absorbs is the colour of the actual deck boards. Just like clothing and other materials, darker colours tend to absorb more heat over time. Therefore, the darker your composite decking, the more heat it will absorb and the warmer it will become. Composite deck boards with a lighter surface tend to retain less heat in comparison to darker finishes. So, if you want to make absolutely certain that your composite deck will be as cool as possible during the summer, greys, cedars and whites are your best option. 

 

Type of Decking Used

The final factor that impacts the amount of heat retained by your composite deck is the type of decking you have installed. This may sound a little confusing at first because you're probably thinking "what do you mean what type of composite decking I use? I use composite decking!" Well, we know that composite is one form of decking, but you can also get different forms of composite decking too. That being capped and uncapped or hollow and solid.

Capped composite decking provides your deck boards with a protective polymer sleeve used to minimise the amount of water absorbed by your deck boards, but it also minimises the amount of heat your boards absorb. Therefore, capped composite decking may, in fact, absorb and retain less heat than uncapped boards. The same can be said with hollow deck boards too. The lighter your boards are in terms of weight and density, the less heat that will be absorbed and retained. 

 

All types of decking, when exposed to summer sun over long periods of time will absorb some degree of heat. Whether that's natural timber decking, IPE decking, plastic decking or composite decking. The latter, however, will definitely retain heat for the least amount of time as a result of the advanced technologies that go into producing it. This benefit, along with its slip and fade-resistance and incredible low-maintenance qualities make composite decking the firm choice amongst homeowners when looking to add a deck area to their garden and outdoor space. 

To have the best and most enjoyable time outdoors, choose a light-coloured, capped, hollow composite deck board. If hollow boards aren't readily available, we recommend choosing a grooved board as this will offer less material than ungrooved boards!
