Expected Service Life
This graphs shows the service life of Accoya versus other building materials as reported in the Heriot Watt report.
Due to Accoya’s improved properties – such as increased durability, improved thermal insulation and longer coating life Accoya wood provides several environmental gains during its use phase. This makes Accoya a good option for those wanting to use sustainable building materials.
The durability of Accoya is Class 1 (EN 350), the highest durability class possible and has extensive quality certifications (KOMO, RAL, BBA, WDMA, etc.) and is warranted to last 50 years above ground and 25 years in ground or freshwater. Compared to most materials Accoya’s longer lifespan enables lower material consumption and less replacement! This also means that Accoya has carbon sequestration advantages as it locks CO₂ for a longer time from the atmosphere. In fact, because of low emissions during production combined with the increased life span and good recyclability, Accoya window frames are even assessed to be CO₂ neutral over the full life cycle. For more information see environmental assessments.
The superior dimensional stability of Accoya means that it requires less frequent coatings maintenance leading to subsequent environmental benefits and lower costs as well. Combined with increased durability the planned Service Life as established by Heriot Watt University is 77 to 90 years, depending on exposure conditions. This means Accoya is much more superior to regular timber but also aluminum and PVC windows.
Finally, compared to other durable wood species, Accoya offers superior thermal insulation, which yields energy conservation advantages in applications such as window frames.
