Advantages
Uses 20% less wood than CLT for equivalent performanceSuperior dimensional stability compared to solid timberPredictable structural performance through gradingCarbon negative - stores approximately 835 kg CO₂/m³Excellent seismic performance with high ductilityAvailable in large panel sizes (3.6m × 14.6m)Multiple structural grades available (F10, F16)100% recyclable at end of life
Cautions
Not manufactured in Australia - import onlyNo Australian Standards compliance testing completedSingle global manufacturer (monopoly supply risk)Requires specialist mass timber connectionsCombustible material requiring fire engineeringNo local technical support availableImport costs and lead times significantRequires weather protection during construction

Developed by Freres Lumber Company in Oregon, USA, with initial patents filed in 2017. First commercial production began in 2018 at their Lyons, Oregon facility. The product emerged as an alternative to CLT, using the company's expertise in veneer production to create a more efficient mass timber panel. Research collaboration with Oregon State University validated structural performance. As of 2025, remains a single-source product with no manufacturing outside the USA. Australian market entry would require comprehensive compliance testing to AS/NZS standards.
