Case study: Wood insulation

3 June 2025

In response to climate challenges and energy efficiency requirements, we must acknowledge the urgent need for the construction industry to transition to bio-based materials as a solution to reduce our collective carbon footprint. Among these solutions, wood fibre insulation stands out given its interesting technical properties, particularly its thermal performance, humidity control and low carbon footprint. However, integrating wood fibre insulation in the Canadian context remains a challenge requiring regulatory changes and technical adaptations.

The new addition to the École des Cerisiers, which constitutes a mass-timber project of 2384 m2, demonstrates the potential of wood fibre insulation in the building envelope. This project combines innovation and sustainability by integrating bio-based materials in both the structure and in the building envelope.

Welcome

Greetings for another Tuesday mass timber update. We’re delighted to say there are only a few seats left for our Christchurch seminar and site visit. Click here to register now!

We’re keen to showcase more mass timber building projects around the regions. If you know of a mass timber project under construction and the project team is happy to host a group, please call and we’ll see if we make it work.

Thanks to those of you’ve offered presentations for our national conference on 4-5 November. We’ve already received a good mix of case study offers and can take 3-4 more if you’re keen.

With the building costs and tight Government budgets making New Zealand’s planned hospital builds more challenging, do you think there is a place for lobbying to build parts of these new assets with exposed mass timber, as biophilic environments are proven to speed recoveries.  How do we do it; got any suggestions? Is there a role for a group of AEC leaders who can make a case for using more mass timber in health facilities?
