In the heart of the Dales National Park, where natural beauty meets architectural heritage, a homeowner in Ilkley sought more than just a window replacement. After experiencing premature failure with his previous timber windows—just five years post-installation—he turned to Patchett Joinery for a solution grounded in quality, longevity, and elegance. 

Their answer? Handcrafted Sliding Sash Windows made from Accoya—high-performance timber with no equal in durability, stability, and design integrity. 

Having completed a full property renovation only a few years prior, the homeowner was clear about what he needed the second time around: 

“Living in the heart of the Dales National Park, it was important to get the correct windows — the correct look for planning consent and the correct materials to withstand the weather.” 

With Ilkley’s varied climate and the home’s historical character, it was essential to find a material that could endure seasonal shifts, satisfy conservation criteria, and remain visually in tune with the property’s timeless aesthetic. 

The specification was clear: Accoya for its proven performance and resilience, and polished chrome hardware from their premium range to elevate the final look.  

“As the client had only had his previous windows five years, specifying the correct materials was of paramount importance,” Patchett Joinery noted. 

Accoya’s unparalleled dimensional stability—swelling and shrinking three to four times less than traditional wood—was instrumental in ensuring a lasting, airtight fit. Its 50-year warranty above ground offered peace of mind that extended well beyond expectations. 

Handmade in Patchett Joinery’s West Yorkshire workshop, the Sliding Sash windows were crafted with Georgian bars to retain the home’s classic elegance, then expertly installed by their experienced team. 

Accoya stands apart in a category of its own: a high-performance wood that redefines what timber can do. Sustainably sourced and Cradle to Cradle® Gold certified, Accoya is designed to last—and made to inspire. 

• Exceptional Durability: Backed by a 50-year above-ground warranty and 25 years in ground or freshwater. 

• Unmatched Stability: Minimises swelling and shrinking, maintaining form and fit over decades. 

• Naturally Beautiful & Highly Versatile: Whether left natural or finished to suit, Accoya elevates any architectural vision. 

This project is a testament to how Accoya transforms the ordinary into the exceptional. In the skilled hands of Patchett Joinery, the material became more than just a window frame—it became a promise of beauty, resilience, and enduring value.
