Radiata Pine, cross-laminated timber (CLT) panel (60mm, 80mm, 100mm, 120mm, 140mm, 160mm, 200mm, 280mm)
Cross-laminated timber (CLT) panels are structural mass-timber elements manufactured by bonding layers of radiata pine boards at alternating 90-degree angles using structural adhesives (MDI or PUR). The cross-lamination creates a bi-directional panel with high stiffness, dimensional stability, and predictable structural performance for walls, floors, and roofs. XLam Australia (Wodonga, VIC) is the dominant domestic manufacturer, producing panels from 60 mm to 280 mm thickness in widths up to 2.95 m and lengths up to 13.5 m. CLT enables rapid, precision-prefabricated construction with reduced wet trades and lower site waste than conventional concrete or steel framing.

Cross-laminated timber was developed in Austria and Germany in the early 1990s, pioneered by researchers at the Technical University of Graz and manufacturers including Stora Enso and Binderholz. The first CLT buildings in central Europe date from approximately 1995–1998. European adoption was driven by a combination of abundant softwood supply, strong engineered-timber manufacturing traditions, and favourable building codes. Australia's adoption lagged Europe by approximately 15 years due to a smaller softwood manufacturing base, less established engineered-timber supply chains, and building codes that historically restricted combustible construction above 3 storeys. The critical regulatory shift occurred with NCC 2016 amendments to the Building Code of Australia, which introduced a Deemed-to-Satisfy pathway permitting timber-framed or mass-timber construction in Class 2–9 buildings up to 25 m effective height (approximately 8 storeys), subject to sprinkler protection and specific encapsulation provisions. XLam Australia established its Wodonga (VIC) manufacturing facility around 2012–2014, becoming the primary domestic CLT supplier and reducing import lead times and costs substantially. Prior to this, projects imported panels from XLam New Zealand or European manufacturers. The period 2014–2020 saw a cluster of landmark Australian mass timber projects that demonstrated CLT's viability: Library at the Dock in Melbourne (2014), International House Sydney (2017), and 25 King Brisbane (2018) attracted sustained industry and regulatory attention. The Australian Timber Development Association (ATDA) and WoodSolutions (Forest and Wood Products Australia) played key roles in disseminating technical guidance and advocating for code reform. NCC 2022 further refined the performance pathway for taller timber buildings, and several projects above 8 storeys are in design or construction as of 2025 using Performance Solutions, pointing to continued growth in Australian mass timber construction.
