Fiberglass door
An entry door with a molded fiberglass skin over an insulated foam core — the premium replacement default.
What it means for you
The best all-round entry door for NC: it won't rot, warp, or swell in heat and humidity, it insulates well, and it can convincingly mimic stained wood with almost no upkeep. For raw pry-bar strength a steel slab edges it, but fiberglass wins on the balance. Watch the storm-door heat-trap warning on dark, sun-facing fiberglass.
