Fiberglass entry doors are very airtight and energy efficient. Fiberglass doors often come insulated, which provides an additional energy saving advantage over wood doors. They offer up to five times the insulating ability of wooden doors.
When most people choose French doors, they usually pick fiberglass doors. Fiberglass gives the door an architectural appeal as well as lets necessary sunlight in when you wish. The average minimum cost of fiberglass French doors is $600 and the average max is $1,700. Note that the higher costs of French doors are usually associated with architectural moldings added to the assembly later on.
