Fiberglass Exterior Doors

Typical builders include steel exterior doors.  The problem with steel is that it can rust.  Fiberglass doors have a double advantage.  A. they don’t rust.  B. they act as a better insulator.  Insight Homes uses fiberglass doors on all* exterior entries.  This includes patio doors, and standard entry doors.  (*Due to fire code, any door leading into a garage is required to be steel.
