At Glyngary Joinery, we only craft high quality products. In order to do this, we only use high quality materials and all of our windows and doors are made with Accoya® timber as standard. But what is Accoya? Read on to find out all about it…

What is Accoya?

Accoya® begins its life as a medium-density Radiata Pine, which reaches maturity in approximately 30 years, making it a fast-growing and sustainable resource. However, to become Accoya®, it needs to undergo a modification process known as ‘acetylation’, where the timber is exposed to acetic acid under controlled conditions, altering its cellular structure. This process essentially fills in all the ‘holes’ throughout the wood to prevent it from absorbing water, ultimately transforming it from a standard wood into a high-performance timber, stronger than hardwood.

The acetylation process permanently changes the properties of the wood, meaning Accoya is exceptionally durable and engineered to last – making it incredibly resistant to the usual problems typically associated with timber windows, like warping, swelling, and shrinking.

Enhanced Stability and Low Maintenance

Thanks to its resistance to moisture, Accoya holds its shape and structure exceptionally well, meaning it isn’t susceptible to warping or cracking. This stability means fewer repairs and less maintenance, even in environments with high humidity or fluctuating weather. Accoya outperforms traditional timber in terms of maintenance, making it a cost-effective and reliable choice for long-term use. Paint finishes on Accoya also last up to twice as long, saving time and money on maintenance.

Superior Insulation and Energy Efficiency

The structural stability of Accoya means windows and doors maintain a tight seal, which is crucial for energy efficiency. When fitted correctly, Accoya windows and doors reduce drafts and help maintain indoor temperatures, leading to lower energy costs. Also, with timber being a natural insulator, its thermal properties further enhance its performance, making Accoya ideal for energy-conscious homeowners.

Environmentally Friendly and Sustainable

Accoya is not only effective but also eco-friendly. Sourced from sustainable forests, this carbon-negative material aligns with responsible environmental practices. The acetylation process itself is non-toxic, with the timber remaining safe and non-hazardous throughout its lifespan. By choosing Accoya, you’re investing in a product that meets today’s environmental standards without compromising on performance.

Ideal for Various Window and Door Styles

Because of its durability and stability, Accoya is perfect for all kinds of window and door designs, including sliding sash windows and casement windows, plus patio, bi-fold and entrance doors. Its ability to maintain form and structure under different weather conditions makes it a standout choice for properties needing long-lasting, beautiful window and door solutions.
