Woodworkers BS&R say Accoya is a solid investment By Amanda Dale adale@bermudasun.bm
In a coastal climate the beauty of natural wood can fade with the elements of sun, wind and salt water, but at carpenters BS&R Group you can now find a sustainable solution. The family woodworking business has started making shutters, (weathersealed) windows and doors from Accoya, a high performance, low maintenance acetylated wood. By purchasing these quality products, not only can you help the environment by using a sustainable wood, but your home will look beautiful for longer. Accoya is radiata pine, a fast-growing tree. It is only sourced from sustainable forests, so when one part of the forest is cut down, another part is replanted at the same time, to ensure reforestation. The wood is sourced from FSC (Forest Stewardship Council), PEFC (Programme for the Endorsement of Forest
Certification) and other regionally-certified woods. Accoya modified wood is produced by Accsys Technologies PLC, that has a wood production plant in Europe, and offices in the Netherlands, the US and UK. The company describes Accoya as “the world’s leading high technology long-life wood”, renowned for durability, stability, reliability and its aesthetics.
Long-lasting BS&R Group brings in the wood as raw lumber, Anthony Madeiros, general manager, said: “Accoya wood has been available for over a decade, but although it’s quite new, the process of treating radiata pine with vinegar has been around for a long time, but was never massproduced. “The technology is basic stuff; it’s essentially using vinegar (acetic acid) on the wood. “They make the vinegar into a vapour, put the wood into a chamber and then pressure-treat the
wood with the vapour.” He said (free) hydroxyl groupings (oxygen and hydrogen atoms) in wood make certain parts more susceptible to water conduction, rot, termites and bugs than others — commonly referred to as sapwood. Free hydroxyl groups absorb and release water according to changes in climatic conditions, swelling and shrinking (‘moving’) the wood. “Acetic acid naturally occurs in wood but this process puts more of it in there and creates a chemical reaction, changing the hydroxyl groups into acetyl groups,” said Mr Madeiros. “This makes the wood impervious to rot and other types of decay.” When transformed to an acetyl group, the ability of the wood to absorb water is greatly reduced, making the wood more stable and durable. The acetylation process is non-toxic and simply See sustainable, page 2
