Accoya timber is a core material in our workshop at Wealden Joinery. From the moment it arrives in our Rotherfield workshop, we know we’re working with a material that sets the standard for performance, sustainability, and style.

Whether we’re crafting Accoya windows or Accoya doors, our clients benefit from durability, security, and a product that enhances homes across the South East.

What Makes Accoya Different From Traditional Timber?

Accoya is not just any timber. It is a high-performance wood created from sustainably sourced softwood that is modified through a process called acetylation. This technique alters the wood’s internal structure, significantly enhancing its resistance to moisture, movement, and decay.

The result is a timber product that outperforms many hardwoods and softwoods, yet is made from fast-growing, responsibly sourced materials.

Accoya’s structure makes it ideal for precision joinery. It resists warping and has excellent paint retention. Unlike many timbers, it remains stable in all weathers, meaning doors and windows open and close easily year-round.

How Durable Is Accoya Timber?

The durability of Accoya is one of its most outstanding features. It is classified as a Class 1 durable wood, which is the highest possible rating for timber. In long-term trials conducted in some of the most demanding climates worldwide, Accoya consistently resisted rot, fungal attack, and degradation.

For homeowners, this translates into timber that does not swell, warp, or distort. Windows do not stick. Doors do not shift. Paint finishes last significantly longer.

Accoya also comes with a 50-year warranty for use above ground and a 25-year warranty when used in contact with soil or freshwater. These are industry-leading figures that bring long-term peace of mind.

Why Wealden Joinery and Accoya Support a More Sustainable Future

Sustainability is a non-negotiable principle for us at Wealden Joinery. That is why Accoya is a material we are proud to work with. It is sourced only from FSC-certified forests, and the acetylation process used to modify the timber is entirely non-toxic. No harmful chemicals are used, and the finished product is fully biodegradable and recyclable.

In addition, Accoya is Cradle to Cradle Gold certified and carries the Nordic Swan Ecolabel, both internationally recognised certifications for environmental responsibility. These credentials mean our clients can enjoy high-performance joinery without compromising on environmental impact.

Our own workshop reflects this same ethos. Wealden Joinery has invested in 108 solar panels on our roof, producing 29.5KVA of renewable energy, which powers much of our daily operations. This investment is part of our wider commitment to reducing our carbon footprint and supporting a more sustainable future for the joinery industry.

The Importance of PAS 24 Compliance for Doors and Windows

Security is a key consideration when designing and installing external joinery. PAS 24 is a UK standard that tests the enhanced security performance of doors and windows against realistic attempted break-ins. It includes a series of rigorous tests involving impact, mechanical force, and manual attack.

Accoya has recently achieved PAS 24:2022 compliance in the UK’s first traditional sliding sash window design to meet this standard. This window combined slimline glazing, robust sash components, and security hardware to pass independent testing at a UKAS-accredited laboratory. For heritage properties and conservation areas, this means you can have authentic design without sacrificing modern security standards.

At Wealden Joinery, we incorporate these same principles into our bespoke Accoya windows and doors. We ensure that what we build not only enhances the character of your home but also helps to keep it safe.

Why Accoya Is Ideal for Bespoke Windows and Doors

Precision matters in joinery. A small shift in timber can mean the difference between a window that glides smoothly and one that jams in humid conditions. Accoya’s remarkable stability ensures that windows and doors operate reliably throughout the year.

In our workshop, we use Accoya for:

  • Heritage-style sliding sash windows
  • Bespoke casements and bays
  • French doors and stable doors
  • Contemporary front doors with fine detailing

Accoya accepts paint and stain with ease, and matches both period and modern aesthetics. For conservation projects or homes requiring like-for-like replacements, it is particularly valuable as it can replicate original features.

Why Our Clients Choose Accoya

Wealden Joinery clients are typically seeking joinery that delivers longevity, reliability, and aesthetic beauty. Increasingly, they are also asking for sustainable materials that do not compromise on performance. Accoya meets all of these requirements.

Traditional softwoods often deteriorate quickly without ongoing treatment. Many hardwoods are expensive, variable in quality, and raise concerns about sustainability. Accoya presents a smarter option. It combines the best of both worlds – the durability and beauty of a hardwood with the environmental credentials and precision of a softwood.
