Our Mission

The IMTA is a nonprofit 501c3 that promotes Mass Timber and Wood Construction. Our focus is securing the future of mass timber in the energy revolution. We focus on sustainability, energy efficiency, low embodied energy, and carbon sequestration.

We help identify mass timber and wood construction barriers in residential and commercial applications. We do this through-

Scientific research and testing in collaboration with post-secondary institutions, government, and non-governmental organizations.
Data collection and using it to develop building codes and energy standards that include Mass Timber and Wood Construction.

Who is the IMTA?

The International Mass Timber Alliance (IMTA) is a nonprofit 501c3 that promotes Mass Timber and Wood Construction. Our focus is securing the future of mass timber in the energy revolution. We focus on sustainability, energy efficiency, low embodied energy, and carbon sequestration. We help identify mass timber and wood construction barriers in residential and commercial applications.

What We Do.

Scientific research and testing in collaboration with post-secondary institutions, government, and non-governmental organizations.
Collecting and using data to develop building codes and energy standards, including mass timber and wood construction.

Phase 1

Initial Modelling & Testing

In Phase 1, we partnered with Oak Ridge National Laboratory (ORNL) to compare and assess standard framed wall components with mass timber CLT components. They tested performance across various thicknesses under varying climate conditions. Read more about it here.

Phase 2

Large Scale Testing with the U.S. Department of Energy

During Phase 2 we moved onto research on the Impact of mass wood walls on building energy use, peak demand, and the thermal comfort of the occupants. This meant research in the field on site in Colorado, Texas, and Tennessee. We built cubes out of CLT to simulate the thickness of log and timber walls.

Phase 3

Influencing Building Codes

We’ve entered the final phase of work now in 2026 and that’s influencing building codes. We’re looking to raise $75,000 to fund this important work. Without your support nothing will change and log homes and mass timber will lag behind and not seen as the smart and energy efficient solutions it is.

Benefits of Sponsorship

The most important benefit of sponsorship in the IMTA is the ability to participate in and support the mass timber industry for the long term. The intent of the IMTA is to identify and be responsive and pro-active to factors that affect the industry’s future. Within that, the IMTA’s 5-year plan is to be active in representing the industry in model building code development and to promote the positive benefits of mass timber construction as the most sustainable building system. Future efforts may study lifestyle cycle benefits, carbon emissions/capture, and other factors pertaining to the mass timber industry.
