In a significant shift towards sustainable construction practices, cross-laminated timber (CLT) is gaining traction in Australia as an eco-friendly alternative to traditional building materials.
This innovative wood product is poised to revolutionise the construction industry by reducing carbon emissions and promoting environmental stewardship.
Thanh Huynh, R&D, Engineering, and Services Director at Knauf Gypsum, emphasises the critical importance of CLT adoption in Australia.
“CLT offers an opportunity to leverage Australia’s forestry industry sustainably, balancing ecological preservation with economic benefits,” Huynh states.
He highlights that CLT aligns with Australia’s diverse architectural needs and rapid urban development, supporting faster construction timelines while minimising environmental impact.
One of CLT’s most significant environmental advantages is its ability to sequester carbon. Unlike concrete, which contributes to about 8 per cent of global CO2 emissions, CLT locks in carbon dioxide absorbed by trees during their growth.
This process not only reduces atmospheric carbon dioxide but also promotes sustainable forestry practices.
The material’s versatility and efficiency have been demonstrated in projects such as Forte Melbourne and the Adelaide Oval Hotel, showcasing CLT’s adaptability to various design requirements while maintaining cost and time efficiency.
Australia can draw valuable lessons from Scandinavian countries, which have successfully integrated CLT into a wide array of construction projects.
Their experience highlights how a concerted effort between policymakers, industries, and the public can drive the transition towards more sustainable construction materials and methods.
In response to these macro-environmental challenges, Knauf Gypsum has collaborated with New Zealand’s Xlam to develop new lightweight wall and floor/ceiling systems specifically tailored for CLT.
These innovations, featured in the recently released Systems+ guide, align with evolving building codes.
As Australia faces increasing environmental pressures and urbanisation demands, CLT presents a promising solution.
By adopting this sustainable material, the Australian construction industry can significantly reduce its carbon footprint, contribute to climate change mitigation, and create more resilient, eco-friendly communities for the future.
