Masswood has proudly expanded its product offering to include a premium range of Accoya timber solutions, engineered to meet the highest standards in durability, stability, and environmental responsibility. Recognised globally as one of the most advanced modified timbers on the market, Accoya is the result of a revolutionary acetylation process that transforms sustainably grown timber into a material with exceptional performance characteristics. Masswood has harnessed these qualities to develop a suite of products including Glulam, Cladding, Decking, and Batten solutions – all crafted to deliver long- term performance in Australia’s demanding climate.

What makes Accoya truly stand apart is its dimensional stability and resistance to decay. It outperforms traditional hardwoods and treated softwoods in virtually every category: it doesn’t warp, swell, or crack, even in exposed or wet environments. With a minimum 50-year above-ground lifespan and 25 years in-ground or freshwater, Accoya is ideal for structural and aesthetic applications that demand longevity without compromise.

Masswood’s Glulam range in Accoya combines structural strength with the inherent benefits of the species. The result is a beautiful, high-performance timber member that are suitable for exposed outdoor use – perfect for pergolas, portal frames, commercial structures and marine environments. The stability of Accoya makes it uniquely suited to Glulam, allowing Masswood to produce long spans and curved elements with precision and confidence.

The Accoya Cladding range is a standout option for Architects and Builders seeking both durability and design flexibility. With its clean, consistent grain Accoya Cladding offers low-maintenance façade solutions with an unmistakably premium appearance. Masswood’s wide offering includes three standard profiles; Shiplap, Rusticated and Bevel available in multiple sizes and finishes plus they can create custom profiles.

Masswood’s Accoya Decking boards offer unmatched performance underfoot. Resistant to moisture, UV degradation, and insect attack, it remains stable and splinter- free for decades, making it a safer and more comfortable choice for high-traffic outdoor spaces. Masswood’s unique splayed profile means that debris falls more easily between gaps, helping to maintain a cleaner surface and reducing long-term maintenance by preventing the buildup of organic matter.

The Accoya Batten range provides endless creative potential and helps solve design challenges such as sun & light control, façade enhancement and visibility management. Lightweight yet strong, the Masswood Accoya Batten profiles hold their form and resist cupping or twisting over time.

By embracing Accoya and offering multiple finishes and colour options, Masswood continues to push the boundaries of what timber can do – delivering sustainable, durable, and beautifully crafted solutions that stand the test of time.
