We are thrilled to share some exciting news from Nightingale Joinery! Recently, our team had the privilege of receiving a training session conducted by a technical expert from Accsys Technologies, the company behind the product Accoya. Following the session, Nightingale Joinery proudly achieved the esteemed status of becoming an Accoya Approved Manufacturer.

What is Accoya?

Accoya wood is produced using a process that alters the wood’s cell structure, improving its strength and durability. It is traditional wood that is modified at a molecular level.

They call the process “The Acetylation Process”, which transforms hydroxyl groups into larger, inert acetyl groups, reducing the cell wall’s water absorption. This process changes the balance of the naturally occurring chemicals in the wood. This irreversible process results in a permanent improvement in the wood’s performance.

This simply means that because of the changes that have now been made to the cells, the wood will repel moisture greatly, reducing the capacity for bound water and therefore swelling and shrinkage. Wood that is not put through such a process will still absorb and release water depending on the weather conditions it is subjected to. This means that the wood will expand and contract, leading to rotting and splitting, reducing the longevity of the wood.

Therefore, we look to use Accoya to manufacture items that are going to be installed in external locations, e.g. windows, doors and shutters. We especially look to use Accoya for items we are manufacturing with smaller, thinner sections, such as a pair of tall window shutters or a door that is narrower and taller than standard to help prevent warping and twisting.


Accoya is a natural wood product sourced from sustainably managed FSC certified forests. With no plastic, resin, or other harmful additives, Accoya is 100% nontoxic, making it an ideal environmental choice.

If you are considering an Accoya project and would like to discuss your ideas or receive more information, we encourage you to get in touch with Nightingale Joinery. Our dedicated team is here to assist you every step of the way.
