Therma-Tru manufactures fiberglass and steel entry door systems designed for durability, energy performance, and residential curb appeal. Golden State Lumber and Showroom supplies Therma-Tru interior and exterior doors for custom homes, remodels, commercial spaces, and new construction throughout Northern California.
Therma-Tru was founded in 1962 when David Wells purchased a building supply company located in Toledo, OH. In 1983 the company launched its fiber classic style; the first fiberglass door on the market creating a product never seen before. An entryway door that looked as beautiful as wood but with exceptional performance. In 2003, Therma-Tru became a part of the Fortune Brand’s family. Today, Therma-Tru is a $750 million company and growing. We are the nation’s leading manufacturer of fiberglass and steel exterior door systems.
For over 20 consecutive years, Therma-Tru ranked number one in “brand most used” in the entry doors category. We were also rated as number one in highest quality in 2021 and 2022. As a brand leader, Therma-Tru is committed to making safe and sustainable products, supporting the communities where we live and work, and leaving a positive, lasting impact on the environment. Through our Thrive initiative, we’re leading the way to a better tomorrow and doing our part to build a better world, every chance we get.
The Therma-Tru difference lies in our system. A Therma-Tru door with genuine Therma-Tru components is a complete door system with components engineered to work together at the most critical points. We manufacture or specify every aspect of our door system, from the glass to the hinges that we also back with our warranty. Our fiberglass door system is backed by a lifetime limited warranty and our Classic craft door system also offers a one-time transferable lifetime limited warranty. Therma-Tru doors go through some of the most rigorous testing in the industry as well, in many cases beyond what is required. This ensures that our products continue to meet the toughest quality and performance expectations. Homeowners have the confidence and convenience of one source to contact for any questions or issues that might come up.
