Structural Performance of Accoya® Wood under Service Class 3 Conditions

The acetylation of wood gives enhanced resistance against fungal decay and improved dimensional stability, benefits which make Accoya® wood particularly suitable for use in external applications. With increasing interest in using acetylated wood in structural applications, Accsys Technologies are continually undertaking studies which add to the database of structural properties of Accoya® wood. This paper describes one such study investigating the structural performance of Accoya® wood under service class 3 conditions and in particular the relative structural performance of Accoya® wood between service classes 1 and 3 and how Accoya compares with solid timber in this regard.
