The Thermo-Rite HERITAGE - our flagship door.
Who We Are:
We are a family owned and operated manufacturing business that has been around since WWII. We have been in the Industrial Midwest of Akron, Ohio since we began. In 2025, we became part of TK Fireside, a company focused on glass fireplace enclosures and founded by Brett Lyren, the grandson of Thermo-Rite Mfg. company founder John Lydle.
TK Fireside is Thermo-Rite fireplace enclosures and a new customer-focused, custom-built family of products being developed with Kim Schedbauer formerly of the David Kimberly Door Company. This high-end, built-to-order line will have new engineering, new material and new finishes not available on the current Thermo-Rite product line-up. We are developing these new product lines over the course of 2026 and look forward to sharing our new vision with you. In the meantime we are focused on providing the current Thermo-Rite product catalog.
What We Do:
We invented the Fireplace Enclosure, and we have been manufacturing them for over 80 years! We set the industry standard for quality and durability and have raised it continually throughout our history.
Why We Do What We Do:
We still believe in our Founder, John E. Lydle’s, ideals: Quality, Affordability and Durability. Everyone should be able to have an elegant and well made Fireplace Door in their home to enhance its’ beauty, save energy and increase its’ value. Our mission hasn’t changed, but our methods and materials have, lighter, stronger and more modular for ease of construction and installation. Be part of our history as we set course for the next 80 years. From our family to yours.
