Each board is crafted from Accoya, a sustainably sourced softwood from New Zealand that undergoes an advanced acetylation process. This chemical-free modification permanently enhances the woods structure, making it dimensionally stable, rot-resistant, and insect-proof even in the harshest conditions.
With a smooth planed finish (PSE) and a pale cream to light blonde colour that weathers gracefully to a silver-grey, this cladding delivers a refined, contemporary look suited to any architectural style. Its low-movement characteristics mean minimal warping or swelling, ensuring crisp, clean lines for decades to come.
Ideal for both residential and commercial projects, Accoya cladding outperforms even tropical hardwoods in longevity offering Class 1 durability and a potential lifespan of up to 60 years above ground.

What is Accoya PSE cladding used for?
Accoya PSE (Planed Square Edge) boards are perfect for modern exterior cladding projects from garden rooms and extensions to commercial faades. Their smooth, straight profile makes them ideal for clean-lined contemporary designs.
Can I order custom lengths?
Yes! If you require bespoke lengths or specific quantities beyond the listed sizes, contact our sales team. Well do our best to accommodate your project needs.
What makes Accoya different from other timbers?
Unlike pressure-treated or tropical hardwoods, Accoya is modified right through to the core using acetylation meaning the entire board is protected, not just the surface. This gives unmatched stability and resistance to decay without the use of toxins.
What fixings should I use with Accoya cladding?
We recommend stainless steel nails or screws, as other metals may react with the timber or discolour over time.
Can I use Accoya cladding indoors?
You can, but its designed primarily for external use where durability and weather resistance are essential. For interiors, you might consider alternative timbers for cost efficiency.
How should I install it?
Weve prepared a detailed installation guide for each cladding profile covering fixings, spacing, and ventilation best practices. You can find it in our Cladding Install Guides section.
How long will Accoya cladding last?
When properly installed and maintained, Accoya cladding can last 5060 years above ground significantly longer than untreated softwoods.
Does Accoya require a coating or paint?
No, it doesnt require it for protection, but coatings can enhance colour and design. Accoya holds paint exceptionally well, so finishes last longer before needing maintenance.
What happens if left uncoated?
If left unfinished, Accoya naturally weathers to a beautiful silver-grey patina without losing performance.
