Advantages of Steel Exterior Doors 

Steel exterior doors are a popular choice for both residential and commercial properties. They offer a variety of advantages that make them a great choice for those looking for a durable, secure, and easily customized entryway. 

When it comes to durability, steel exterior doors are hard to beat. Steel is one of the strongest and longest-lasting materials, and it doesn’t rust or corrode over time. Steel doors are also fire-resistant and can withstand extreme temperatures, making them ideal for any climate. 

Security and safety are another great benefit of steel exterior doors. Steel is one of the safest materials and does a great job of keeping people out. Steel doors are also usually equipped with deadbolts and other lock systems to further increase their security. 

Finally, steel exterior doors are also easily customizable. You can choose from different finishes, colors, and styles to match the style of your home. Steel exterior doors are also available in different sizes and styles, so you can find the right one for your front door. 

Advantages of Fiberglass Exterior Doors 

When it comes to exterior doors, fiberglass has become an increasingly popular choice for homeowners. There are a number of reasons why fiberglass exterior doors are a good choice. 

Maintenance and Cost 

Fiberglass exterior doors are easy to take care of and don’t cost as much as other options. Aside from regular cleaning, they don’t need any extra care. Fiberglass doors are also very strong, so you won’t have to replace them as often as you would with other types of exterior doors. They are also resistant to cracking, shrinking, and warping. 

Variety of Styles 

Fiberglass exterior doors come in many different styles and designs, so you can find one that matches the look of your home. Whether you want a classic look or a more modern one, you have a lot of choices. You’ll also be able to make your door fit your home by choosing the color and hardware. 

Energy Efficiency 

Fiberglass exterior doors are highly energy-efficient. They are made to keep air out and can help keep your home warm in the winter and cool in the summer. They also help keep outside noise down. Nevertheless, to get best results, you should buy them from a trusted company like STL Windows and Doors.

Comparison of Steel and Fiberglass Exterior Doors 


Steel doors are extremely durable and can last up to 40 years with proper maintenance. On the other hand, fiberglass doors can last up to 25 years with proper maintenance. Steel doors are also more resistant to scratches, dents and dings, while fiberglass doors can be more easily damaged. 

Security and Safety 

Steel doors are much more secure than fiberglass doors as they are more difficult to break into. Steel doors are also more fire-resistant, making them the better choice for added safety. 

Maintenance and Cost 

Steel doors cost more than fiberglass doors, but they don’t need as much upkeep over time. Steel doors don’t need to be painted or stained, so they’re less expensive to maintain. On the other hand, fiberglass doors need to be painted or stained often to keep their look. 

Variety of Styles 

Steel doors can be made to fit any size or shape. They come in many different styles. Fiberglass doors come in many different styles, but you can’t change them as much as you can with steel doors. 

Energy Efficiency 

Most of the time, steel doors save you money on your energy bills because they keep heat in better than fiberglass doors. When the insulation is done right, fiberglass doors use less energy. 


In conclusion, it really depends on the specific needs of the homeowner. Steel doors last longer and are safer, but they are heavier, and are harder to put in than fiberglass doors. Fiberglass doors are lighter, and easier to install, but may not be as secure. The best thing to do is weigh the pros and cons of each material and choose the one that fits the homeowner’s needs best.
