Our Founder - H.R. Kirby, Sr.

H.R. Kirby, Sr. was one of the original employees with Owens-Corning Fiberglass.

Founded Kirby Fiberglass, Inc in 1946.

His expertise in the manufacture, production and use of glass fibers is the cornerstone of the success of Kirby Fiberglass.
Mr. Kirby, Sr. devoted a lifetime into the development and application of high quality glass fiber roofing products.
Much of his engineering, design and innovation are seen in the glass fiber roofing products that we manufacture and offer to you today.

Dr. Herbert Kirby, H.R. Kirby Sr. and Mrs. H.R. Kirby’s son, was actively involved in the business in his early high school years. After pursuing other careers, and earning several technical degrees including two master degrees and one doctorate, he returned to the family business.
