Types of Decking Boards Available in the UK

Before choosing where to buy decking boards, it helps to understand the main types available.

Timber Decking Boards

Traditional timber decking boards are typically made from softwood or hardwood. They offer a natural appearance but usually require regular maintenance such as staining or oiling.

Composite Decking Boards

Composite decking boards are manufactured from a combination of recycled wood fibres and polymers. These boards are designed to offer improved durability and reduced maintenance.

Our guide Composite Decking UK Guide explains how composite materials work and why they have become increasingly popular.
