5/4x5 Accoya One Sided Pre-Grooved decking combines the natural beauty of real wood with exceptional durability, stability, and installation efficiency. The narrower board profile creates a more detailed deck surface, while the one sided groove is designed for hidden deck fasteners, delivering a clean, fastener-free appearance that complements both traditional and contemporary outdoor spaces.

Accoya wood is engineered to resist swelling, shrinking, rot, and insect damage, making it an excellent choice for decks in humid climates, coastal environments, and demanding exterior conditions. Its outstanding dimensional stability helps boards stay flatter and more consistent over time, contributing to a beautiful, long-lasting deck.
