Our Team

Duratherm is led by President and owner, Tim Downing and Vice President, Keith Birden.  For these two, Duratherm is more than just a career – it has been their life’s work for over 40 years each.   While they respectively bring a wealth of experience and expert knowledge to the table, it comes from decidedly different perspectives.  Tim is the face of the business inside the facility in Vassalboro, ME.  He walks the production floor daily—not simply to oversee operations, but to stay connected to the people and the process. He knows each team member and understands the value of their individual contributions. Keith is the face of the business outside of the facility, in architect’s offices, and visiting job sites from coast to coast.  His deep passion for architecture fuels and shapes every project he touches.  Guided by a shared commitment for excellence, this collaborative duo believes that lasting success comes from continuously improving both the product and the people behind it. Their combined expertise and complementary strengths create a powerful partnership—driving innovation, elevating customer satisfaction, and fostering a positive, high-performing environment for the entire team.

Duratherm employees come from diverse backgrounds, each bringing indispensable skills and expertise that are vital to our operations.  We take pride in the fact that the average tenure of our team members is over 16 years, with our management team averaging an impressive 23 years.   Experience is key, and it’s something we have in abundance throughout the organization.

While we may be small, we are mighty.  We like to say, we are big enough to get the job done, but small enough to turn on a dime.  With direct access to ownership and less layers of management, we can quickly pivot, adapt to changes, and get the project done without the delays or complexities found within larger organizations.
