Wood Doors vs. Steel Doors vs. Fiberglass Doors

Even after 25 years, fiberglass remains the most advanced material for entryways — able to satisfy both today’s and tomorrow’s homeowners by giving them the look of wood doors and the strength of steel doors, without the compromises of either. In fact, fiberglass doors offer just what homeowners want* — the optimum combination of security, energy efficiency, performance and aesthetics. Therma-Tru not only pioneered the fiberglass door category but we continue to lead the industry.
