Following a successful rebrand, premium timber window and door manufacturer Glyngary Joinery has reported significant business growth, closing 2025 almost double its 2024 size, with a 95 percent year-on-year increase in top-line revenue. The results underline the company’s strengthening position within the timber window and door fabrication sector.
The Cheshire-based manufacturer attributes this growth to a steady stream of new trade customers - particularly installers and trade counters - alongside increased demand from existing partners. Central to this momentum is the company’s ongoing mission to re-educate the sector on the benefits of targeting the premium end of the market and selling high-performance timber products.
“Accoya, a scientifically modified pine, has completely transformed timber’s proposition in the UK fenestration market,” explains Joe Trueman, Director of Glyngary Joinery. “Accoya is our standard offering. It comes with a 25-year warranty and a 70-year life expectancy. It’s thermally efficient, achieving full window U-values of 1.2 with standard double glazing and as low as 0.68 with triple glazing. At the end of its long lifespan, it’s also fully biodegradable and recyclable.
“Despite the industry’s best efforts, much of the old uPVC removed still ends up in landfill. Because of this - and the clear performance advantages of Accoya - we’re seeing timber make a strong comeback in the UK market.”
“Over the last 18 months, we’ve invested heavily in our brand, marketing assets, software and manufacturing machinery. This has enabled us to scale confidently and sustainably, almost doubling in size within a very short period of time.”
