Mass Timber Insurance Playbook

About the Playbook

The objective of the Mass Timber Insurance Playbook is to enable a collaborative approach between construction teams and insurers, opening the door to more equitable insurance for mass timber buildings.

Mass timber has the potential to reduce the embodied impact of construction versus more conventional materials such as concrete and steel. It is strong and light, and as a natural material, has a strong aesthetic appeal. But, especially since the Grenfell disaster, mass timber projects have sometimes faced difficulty securing insurance.

The Mass Timber Insurance Playbook is a direct response to the challenges developers have faced, providing guidance for all parties involved in arranging insurance – for both development and operation of projects.

The Playbook was written by insurance and building resilience specialists, to help stakeholders in the insurance and construction industries to understand each other’s priorities and language. The aim is to enable constructive communication, to help overcome gaps in understanding that sometimes hold back mass timber construction.

Prof. Glockling authored, in association with UK insurers, the widely circulated 2022 industry publication which described the insurance challenges of mass timber construction.

In support of the project, ASBP was awarded a €97,000 Accelerator Fund from Built by Nature, a network and grant-making organisation with a mission to accelerate the timber building transformation in Europe. Co-funding of €17,400 and in-kind expertise are provided by global insurance broker Marsh, and Zurich Resilience Solutions, part of Zurich Insurance Group.

Timber Accelerator Hub

The Mass Timber Insurance Playbook is a continuation of work that began with the Timber Accelerator Hub, which culiminated in a report shedding light on the major challenges faced by developers in their attempts to reduce carbon emissions in new building projects. It recommends a series of potential solutions that could unlock significant carbon savings through an increase in the use of mass timber.
