Where are Therma-Tru doors manufactured?

Therma-Tru doors are manufactured in the United States at plants in Ohio, Indiana, and other locations, with headquarters in Maumee, Ohio. Therma-Tru was founded in 1962 in Toledo, Ohio, and operates its main manufacturing facilities in Maumee, Ohio for fiberglass door skins and assembly, and in Butler, Indiana for steel and fiberglass doors, plus other facilities in the Midwest. Therma-Tru is owned by Fortune Brands Innovations, which is headquartered in Deerfield, Illinois, but manufacturing remains primarily in Ohio and Indiana with American workers. Therma-Tru fiberglass doors are made by molding fiberglass skins with wood grain textures, injecting foam core for insulation, and assembling into slabs and pre-hung systems with frames, weatherstripping, and sills. Steel doors are made by forming steel skins and injecting foam core. All Therma-Tru doors sold in North America are made in these US plants with components like glass, hardware, and frames sourced from suppliers but final assembly and quality control done in Ohio and Indiana. Therma-Tru emphasizes American manufacturing, with plants that include sustainability programs. So when you buy Therma-Tru doors at Home Depot, Lowes, or dealers, you are buying doors manufactured in Maumee, Ohio and Butler, Indiana.
