The two most popular types of exterior doors are steel and fiberglass. Both have their own advantages and disadvantages, so it’s important to know which one is right for your home before you make a purchase.

Here are some things to keep in mind when you’re comparing steel and fiberglass doors:

Cost: Steel doors are usually cheaper than fiberglass doors.

Maintenance: Fiberglass doors require less maintenance than steel doors. They don’t rust or rot, and they don’t need to be painted as often.

Insulation: Fiberglass doors are better insulated than steel doors, so they can help keep your home warm in the winter and cool in the summer.

Noise: Fiberglass doors do a better job of blocking out noise than steel doors.

Steel Doors

Steel doors are a popular choice for exterior doors because they are strong and durable. They can withstand extreme weather conditions and are not susceptible to warping, rotting, or cracking. Steel doors are also low maintenance and are available in a variety of styles.

Advantages of Steel Doors

Doors made of steel are more expensive than fiberglass doors, but they offer several advantages.

Steel doors are stronger and more durable than fiberglass doors, and they’re not susceptible to warping or cracking in extreme temperatures. They’re also more secure, since it’s difficult to break through a steel door. Fiberglass doors can be reinforced with steel for added security.

Steel doors require less maintenance than fiberglass doors, since they don’t need to be repainted or refinished as often. They’re also easier to repair if they’re damaged.

If you’re looking for a door that will provide maximum security and durability, a steel door is the best choice.

Disadvantages of Steel Doors

While steel doors have many advantages, there are a few disadvantages to consider as well:
-They are prone to denting and can show scratches more easily than fiberglass doors.
-They can be noisy, especially in inclement weather.
-They may require more maintenance than fiberglass doors, such as painting or rust prevention.

Fiberglass Doors

Fiberglass doors are an excellent choice for an exterior door because they are durable, energy efficient, and easy to maintain. Fiberglass doors are made of glass fibers and resin, making them much stronger than traditional doors. They are also energy efficient because they have great insulation properties.

Advantages of Fiberglass Doors

Fiberglass doors offer many advantages over steel doors. Fiberglass is stronger than steel, making it more resistant to impact damage. It also doesn’t dent or ding as easily as steel, so your door will keep its good looks for longer. Fiberglass is also a better insulator than steel, so your home will be quieter and more energy-efficient.

Disadvantages of Fiberglass Doors

Fiberglass doors have a few disadvantages compared to steel doors. One is that they can be difficult to repair if they are damaged. If a steel door is dented, it is fairly easy to remove the dent. If a fiberglass door is damaged, it is often necessary to replace the entire door.Another downside to fiberglass doors is that they are not as strong as steel doors. This means that they are more likely to be damaged in a high wind or if something hits them hard, such as a baseball.


There really is no clear winner between steel and fiberglass doors. It really depends on your particular needs and preferences. Steel doors are generally more durable and require less maintenance, while fiberglass doors are typically more energy efficient and can better mimic the look of wood.
