Steel and fiberglass sectional garage doors are among the more popular entry door materials today, due to their relative strength and durability, especially when compared to wood. Consumers may find it difficult to choose between these materials because of their similar qualities, though careful consideration will reveal some subtle differences between steel and fiberglass doors.
When comparing mid to low-grade steel or fiberglass sectional garage doors, the cost difference between the two is fairly negligible. If one is looking at high-end doors however, fiberglass will almost always cost significantly more than steel. At the other end of the spectrum, both steel and fiberglass sectional garage doors can be found at relatively low prices, though steel is often the better buy. A cheap steel door may flake or peel, but a low-quality fiberglass door tends to crack or rot.
Steel overhead garage doors are usually better insulated than fiberglass units. This is due to the construction differences between the two doors. Steel doors are really steel-skinned, with a foam core that helps to keep cold air out of the home. Fiberglass sectional garage doors are usually solid all the way through, and lack the insulated core found in steel doors. At the same time, steel has a higher level of thermal transfer than fiberglass. This means that steel overhead garage doors will be very cold in the winter and very hot in the summer. In extreme temperature conditions, this could be an issue worth considering before making a purchase.
Most fiberglass roll up garage doors feature integral color that extends through the thickness of the door. If these roll up garage doors are scratched or scuffed, the damage is not very noticeable. Steel roll up garage doors, on the other hand, are painted at the factory or during installation. If steel roll up garage doors are dented or scratched, the damage is particularly noticeable because the natural metal color will show through. Fiberglass requires little to no maintenance while the most carefully protected steel roll up garage door will usually require repainting every few years.
One of the most popular types of fiberglass entry doors are those with simulated wood grain. These doors offer the look of wood without the maintenance. While steel roll up garage doors can also be embossed to resemble wood, they are not nearly as realistic as fiberglass versions. For flush or panel doors however, both steel and fiberglass look very similar, and can be difficult to tell apart from one another at a distance.
One of the primary benefits of a fiberglass doors is its long lifespan. Once installed, these doors can be left untended for years, while a steel door may rust or corrode. Untreated rust or corrosion can compromise the lifespan and security of the door. The only situation where steel will likely be more durable than fiberglass is in a very cold setting. At extreme temperatures fiberglass may crack, especially when subject to impacts and abuse.
