The Alliance for Sustainable Building Products (ASBP) has launched an international project to develop practical guidance on managing water and moisture risk throughout the lifecycle of mass timber buildings. Funded by the Softwood Lumber Board (SLB) and Swedish Wood, the project will bring together existing research and industry expertise to produce practical guidance on the design, construction and long-term management of mass timber buildings. With mass timber being adopted in a wider range of building types, the ASBP said practical guidance would help build confidence for the industry and insurance providers. The guidance will build on the success of the Mass Timber Insurance Playbook, published by ASBP and co-authored by Dr Jim Glockling. …the principles of moisture management are governed by universal building physics. The guidance will therefore be developed as an internationally applicable resource, with regional considerations added where appropriate. It is scheduled to be published in October 2026.
