Exterior doors for your home are available in many different materials, including wood, steel, and fiberglass. Each has its own benefits and drawbacks, and the one you choose may depend on your particular situation. However, a fiberglass door offers several advantages over those made from other materials. You should know about these advantages in order to make an informed decision.


Fiberglass panels come in the same styles that wooden doors do. Like wood, fiberglass can be painted in the color of your choice. This can be accomplished more quickly with fiberglass than with a wood door because you do not need to apply any primer. Some fiberglass doors can also be stained.

Energy Efficiency

A fiberglass door can help keep your home cooler in the summer and warmer in the winter. This is because the transfer of cold and heat is slowed down significantly by an industrial foam filling that is very dense.


Steel and wood doors are both susceptible to damage caused by exposure to outdoor weather conditions of water and sun. Fiberglass doors, however, do not rust, warp, or rot. Unlike a wood door, a fiberglass model has no veneers or joints into which water can seep, and unlike steel, fiberglass does not become uncomfortably hot when exposed directly to the rays of the sun.


While more expensive than a steel model, a fiberglass door is comparable in price to a wooden one and may even cost a little bit less. The advantages that fiberglass offers over wood, particularly for an exterior door, make it a very good value.


Manufacturers of prefinished fiberglass doors are increasingly able to produce an appearance similar to wood, sometimes right down to the knots. This is helpful for those who like a more natural look but also want the advantages that fiberglass provides.

Improper door installation may negate the benefits that fiberglass has to offer. Be sure to have your door professionally installed.
