Accoya® GluLam beams were specified for use as an external foundation support detail for an innovative low carbon affordable home in the Scottish Highlands. This detail was identified in collaboration with Neil Sutherland Architects (NSA) LLP where the use of Accoya® GluLam would result in enhanced performance in exposed conditions. The Accoya® GluLam provides support to the superstructure formed from offsite fabricated closed panels therefore reduced movement over time due to moisture fluctuations was identified as a key design consideration in order to ensure serviceability criteria are met. Due to the nature of Accoya® (acetylated timber) a test programme was developed to determine its mechanical properties for specification as a structural component both in isolation and in combination. In order to assess the long term performance of acetylated GluLam a number of beams are currently being monitored using in-situ monitoring equipment over a minimum period of 12 months.
