Product Description
Create a premium outdoor space with our Elm Premium Dual-Capped Composite Decking Boards (3660mm), designed to combine the natural appearance of timber with the enhanced durability, protection and low maintenance benefits of advanced capped composite decking.
Built for homeowners looking for a more premium alternative to standard composite decking, our Premium Dual-Capped range features an advanced protective outer layer that helps resist moisture, staining, fading and everyday wear, helping your decking maintain its appearance for longer with less ongoing maintenance.
Finished in a rich Elm wood-effect finish, these boards feature warm brown and teak-inspired tones designed to closely replicate the appearance of natural timber, making them an excellent choice for homeowners looking to create a warmer, more traditional outdoor aesthetic without sacrificing modern durability.
As a fully reversible board, the reverse side features Jade, offering a softer grey-brown finish and giving you the flexibility to choose the look that best suits your project during installation.
Constructed with a durable 22mm profile and strengthened seven-chamber core design, these boards are engineered to deliver long-term strength, stability and reliable performance across all types of outdoor environments.
Perfect for gardens, patios, terraces, balconies and commercial projects, our Premium Dual-Capped Decking provides the appearance of natural timber without the ongoing sanding, staining or maintenance associated with traditional wood decking.
