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 that is still removed 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. Operating from our 40,000 sq ft manufacturing facility in Cheshire, we also have significant capacity to support continued growth over the next five years.”
Quote intake in January and February reached record levels, reflecting growing confidence among Glyngary’s trade customers. As more installers recognise the value of targeting the premium market – rather than competing in a race to the bottom on price – they are seeing stronger, more profitable returns.
Glyngary delivers nationwide and, unlike most timber window manufacturers in the UK, does not install. By staying focused purely on manufacturing, the company is able to dedicate 100 percent of its energy to supporting its trade partners’ growth, rather than competing with them.
In November 2025, Glyngary made further significant investments in production capacity, ensuring the business is well-positioned to build on its recent 95 percent growth.
