While the eco-credentials for mass timber (or engineered wood products) are clear, they will continue to be perceived by insurers as a risky product. Mass timber has a degree of inherent fire resistance which can be enhanced with appropriate design and engineering, but it is nevertheless a combustible product and where disaster strikes can lead to catastrophic consequences and total loss. It is also susceptible to water damage, mould and rot. The frequency of damp or water ingress events is high. Care must be taken to ensure appropriate protection from exposure to weather during transit, site storage and indeed during the construction phase itself. As a relatively new material for large scale projects, knowledge and understanding of the properties and performance of mass timber is a developing science. Mistakes in design and installation are occurring. Further, the absence of historical data on the repair and replacement of mass timber structures makes underwriting challenging for insurers. Yet mass timber is a strong and sustainable product, and its use can be cost-efficient. Looking forward, education, training and data is needed to support the adoption of mass timber and to move away from carbon-intensive materials.
