The secret inside Accoya: How acetylation transforms ordinary wood

Wood is a remarkable and versatile material, but it falls short when exposed to the elements. Repeated cycles of sun and rain cause it to swell, shrink, and eventually decay. But why does this happen? And more importantly—can we change it? 🎥 Discover the groundbreaking science behind Accoya wood in this short 3D animation. Take a closer look inside the structure of wood to understand the root of the problem. Moisture-loving hydroxyl groups absorb water, leading to swelling and instability. As the wood dries, it shrinks—causing cracks and long-term damage. This is where Accoya wood stands apart. Through a precise acetylation process using acetic anhydride, combined with just the right heat and pressure, we increase moisture-resistant acetyl groups and reduce the water-attracting hydroxyl groups. The result? Wood with exceptional dimensional stability, durability, and resistance to rot—built to endure the elements. 🔬 Learn how acetylation: • Reduces moisture absorption at cellular level • Minimises swelling and shrinkage • Enhances durability and dimensional stability • Supports sustainable building practices This is Accoya - the pinnacle of sustainable, high-performance wood, renowned for its unmatched durability and dimensional stability, all backed by an outstanding warranty. Join us and explore the innovation that's redefining the future of timber. 🎧 This version features a UK English voice over.
