Accoya® is the brand name of a treated wood created via the acetylation wood modification process, using acetic anhydride, of Accsys Technologies PLC. Accoya® wood is manufactured via a non-toxic treatment and uses fast-growing softwood timber from sustainable sources. The treated wood has very high durability and dimensional stability allowing for reduced maintenance and is a viable alternative even to high-energy man-made materials."〔(【引用サイトリンク】 Accoya Wood )〕 == Attributes == Accoya® wood gives environmental advantages over slow-growing hardwoods, woods treated with toxic chemicals, and non-renewable carbon-intensive materials such as plastics, metals and concrete. Accoya wood is FSC and PEFC and Cradle to Cradle design certified.〔(【引用サイトリンク】title= Performance )〕 Accoya wood has a durability classification of 1 (EN350-2. Classification Tests: EN113, EN252, ENV807).〔(【引用サイトリンク】 Accoya Wood )〕 The New Zealand Forest Research Institute performed durability testing of Accoya and concluded; "Radiata pine sapwood, declared as Accoya produced by the Accsys Technologies process was exposed in accelerated decay chambers and in exterior ground contact tests. After six years, the Accoya wood had some discolouration but only occasional minor decay. It was in better condition than the heartwood of four naturally durable species and radiata pine treated with CCA to the H3.2 and H4 specifications".〔(【引用サイトリンク】 Durability of Accoya Radiata Sapwood )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Acetylated wood」の詳細全文を読む スポンサード リンク
