In the world of bespoke joinery, sustainability has become more than a trend; it is now an essential standard of quality. Homeowners are increasingly looking for wooden windows and doors that not only look beautiful but also perform exceptionally well while being kind to the environment. This is where Accoya wood stands out as a revolutionary material that is transforming how craftsmen and designers approach joinery.

What Makes Accoya Different

Accoya is an advanced type of modified timber made through a process called acetylation. This innovative treatment enhances the natural properties of softwood, making it stronger, more durable, and resistant to rot. Unlike traditional timber, Accoya does not rely on toxic preservatives or coatings to achieve its impressive lifespan. Instead, it undergoes a sustainable chemical process that stabilises the wood fibres, ensuring minimal movement, swelling, or shrinkage even under harsh weather conditions.

The result is a material that performs as well as, or better than, tropical hardwoods while being sourced from responsibly managed forests. It has earned recognition from global sustainability bodies, including the FSC® and Cradle to Cradle Certified® Gold, demonstrating its positive environmental impact throughout its lifecycle.

A Perfect Match for British Architecture

For many UK homeowners, maintaining the authenticity of period properties while upgrading energy efficiency can be challenging. Accoya’s remarkable versatility makes it an ideal choice for restoring traditional Georgian, Victorian, and Edwardian windows and doors. Its stability and workability allow expert joiners to replicate intricate historical designs without compromising structural integrity.

Whether it’s elegant sash windows or classic French doors, Accoya offers the strength and precision needed to achieve a flawless finish. Its ability to hold paint exceptionally well also means less maintenance and longer-lasting colour, which is particularly valuable in the UK’s often unpredictable climate.

The Sustainability Advantage

One of Accoya’s greatest strengths lies in its environmental credentials. Unlike hardwoods that can take decades or even centuries to mature, Accoya is produced from fast-growing, sustainably sourced pine. This makes it a renewable and eco-friendly option that supports responsible forestry practices.

Additionally, Accoya has a significantly lower carbon footprint than aluminium or uPVC alternatives. Its extended lifespan – often exceeding 50 years – reduces the need for replacements, which in turn lowers waste and long-term costs. Homeowners can therefore enjoy peace of mind knowing their choice contributes to a greener future without sacrificing quality or style.

Craftsmanship That Complements Innovation

Sustainability and craftsmanship are most powerful when they go hand in hand. Skilled joiners who understand how to work with Accoya can bring out the best of this remarkable timber, creating bespoke pieces that blend traditional artistry with modern performance. The wood’s stability ensures precise joinery, smooth operation, and a premium finish that remains consistent year after year.

One fine example of this partnership between material and mastery is seen in Accoya sash windows by Todi & Boys, where durability meets timeless elegance. These windows combine the classic beauty of traditional joinery with the environmental and structural benefits of modern wood technology.

Setting New Standards for Quality and Longevity

Choosing Accoya is not just an investment in your home’s appearance; it’s a commitment to quality, performance, and environmental responsibility. Its proven durability, outstanding stability, and unmatched sustainability make it the benchmark for future-focused joinery.

Todi & Boys exemplify how innovation and craftsmanship can coexist seamlessly. By embracing materials like Accoya, they continue to deliver bespoke windows and doors that stand the test of time – ensuring London homes remain beautiful, efficient, and sustainable for generations to come.
