What is composite decking made of?
Composite decking is made largely of synthetic materials such as PE, PP, and PVC, with a growing range made from eco-friendly recycled plastic. Wood fibres are added to the mix to make the boards stronger. Typically, wood-plastic composite decking contains around 50% wood fibers and 50% thermoplastic, though the mixture varies by design.
What is co-extrusion decking?
Wood composite decking is made from sustainable wood fibers and recycled plastic — but when it undergoes a process called co-extrusion, it becomes far more resistant to scratches, heat, and water. This protective outer layer gives the decking a much longer lifespan, prevents staining, and fully protects it from the elements.
Is composite decking cheaper than wood decking?
Hardwood decking like ipe and oak can be very expensive, while softwood decking like pine is often cheaper. Composite decking is usually cheaper than hardwood but can cost slightly more than softwood options. The difference is returned in longevity — an average composite board lasts well over 20 years.
Is composite decking environmentally friendly?
Composite decking boards and tiles are made with a large proportion of recycled materials such as bottles and consumer plastics, preventing them from going to landfill. They also incorporate timber particles that would otherwise be discarded. And because they last so long, they won’t need replacing every 10–15 years like wood planks do.
What colors of composite decking can I choose from?
With wood, you can paint or stain — but it needs redoing every few years. With composite decking, the color is built into the product. Choose from light and dark browns that simulate real wood, darker architectural blacks and ebonies, or lighter greys, beiges, and creams that make enclosed spaces feel more open.
How do I look after composite decking?
Composite decking requires minimal maintenance. Keep it brushed free of leaves in autumn, and clean it occasionally with warm water and a little soap. It’s water-resistant, so unlike wood it won’t rot or stain — making it one of the easiest decking options to maintain.
How long will my composite decking last?
Composite decking is engineered from resilient materials that stand up to every season. While regular decking needs replacing every 10–15 years, composite decking retains its color and strength for 20–30 years — a fantastic option for a low-maintenance home.
