Choosing Between Fiberglass and Steel Doors: What You Need to Know 

When it comes to choosing a new door for your home, you have a few options. Fiberglass and steel doors are both popular choices for their durability and strength. But how do you know which one you should choose?

In this article, we’ll talk about the differences between fiberglass and steel doors and help you decide which one is best for your home. We’ll also look at the pros and cons of each option, so you can make an informed decision.

Benefits of Fiberglass Doors

Fiberglass exterior doors have many advantages over other types of doors. From durability to insulation to customizability, fiberglass doors are a great option for homeowners looking for a low-maintenance, aesthetically-pleasing entryway.

Durability: Fiberglass is incredibly strong and resilient against wear and tear, with the ability to withstand the elements better than wood or metal. Fiberglass doors can last longer than other doors because they are strong and durable. This saves you money in the long run.

Insulation: Fiberglass’s insulation properties make it an excellent choice for controlling temperatures inside the home. Fiberglass exterior doors are made to keep the temperature inside the house more stable, which can help you save money on heating and cooling costs.

Low Maintenance: Unlike wood, fiberglass exterior doors require minimal maintenance. The material won’t rot, rust, or need to be painted, which makes it a great choice for homeowners who are always on the go. All that needs to be done is to clean it once in a while, if necessary.

Customization: Fiberglass is very easy to change, so you can make a door that fits your style and tastes. You can make the perfect door for your home with pre-hung doors, decorative glass panes, and different colors, shapes, and sizes.

Benefits of Steel Doors 


Steel doors are incredibly durable and can withstand a great deal of wear and tear. This makes them ideal for busy households and commercial buildings that require a lot of traffic. Steel doors are also less likely to break or crack than doors made of other materials. This makes them an ideal choice for longevity.

Strength and security

Steel doors are extremely strong and secure. Unlike other materials, steel is not easily breached and can handle a lot of force. Steel doors also have the added benefit of not catching fire and being able to withstand strong winds and storms.

Low Maintenance

Once they are put in, steel doors don’t need much maintenance. They won’t rust, and a damp cloth is all you need to clean them. This makes them ideal for those who want to save time and money on maintenance and repairs.

Factors to Consider When Choosing between Fiberglass and Steel Doors

Cost is often one of the most important factors to consider when choosing between fiberglass and steel doors. In general, fiberglass doors are more expensive than steel doors, but depending on the style and features you choose, you may be able to find fiberglass doors that cost less. Fiberglass doors are also more energy efficient than steel doors, so if you’re looking to save on energy costs, they may be the better choice.

Location is another factor to consider when choosing between fiberglass and steel doors. Fiberglass doors work well in places like bathrooms and laundry rooms where there is a lot of moisture. 

On the other hand, steel doors are more durable and work better outside. Reputable companies like STL Windows and Doors offer both options, so you can choose the material that is best for your space.

Style is another factor to consider when choosing between fiberglass and steel doors. Fiberglass doors come in many different styles, from sleek and modern to traditional wood grain. Steel doors come in a wide range of styles, from traditional carriage house doors to modern glass doors and more.

Security is an important factor to consider when choosing between fiberglass and steel doors. Steel doors are incredibly strong and secure, making them ideal for keeping intruders out of your home or business. Fiberglass doors are also secure, but they may not be as strong or durable as steel doors. When it comes to security, it’s important to choose a door that best fits your needs.

Finally, maintenance is something to consider when choosing between fiberglass and steel doors. Steel doors should be oiled or treated every so often to prevent rust and corrosion, but fiberglass doors don’t need much care.


In the end, when choosing between fiberglass and steel doors, it’s important to think about the pros and cons of each. Steel doors are more secure and last longer, but fiberglass doors are more energy efficient and don’t cost much to maintain. Ultimately, the best option will depend on your personal needs and preferences.
