When I faced the same choice last year, I thought steel would automatically be the better option because of security. But once I started comparing insulation and long-term durability, fiberglass made more sense for my situation. My old steel door used to get really cold in winter, and you could feel the draft around the edges. After switching to fiberglass, the temperature inside my hallway stopped dropping so much, and the surface didn’t show dents from everyday bumps. Before deciding, I checked different models and specs — If you need durable and modern doors, check their front doors options. It helped me understand the differences more clearly. Honestly, the look and texture of fiberglass ended up fitting the style of my house better too, so the choice was easier in the end.
