1x5 Accoya Tongue & Groove

1x5 Accoya Tongue & Groove combines the natural beauty of real wood with exceptional durability and long-term stability for interior and exterior applications. The tongue and groove profile creates a smooth, seamless appearance with tightly fitted boards, while the narrower width adds visual detail and design flexibility for ceilings, soffits, wall coverings, and cladding projects.

Accoya wood is engineered to resist swelling, shrinking, rot, and insect damage, making it an excellent choice for humid climates, coastal environments, and other demanding conditions. Its outstanding dimensional stability helps maintain tight joints and a clean, consistent appearance over time.
