Here’s a quick overview of fiberglass vs steel doors to help you make an informed decision:

Fiberglass Doors
Fiberglass doors are made from a combination of glass fibers and resin. They are designed to resemble wood, but without the upkeep or vulnerability to weather and pests. Fiberglass doors can be stained or painted to match the look of your home’s exterior.

-Low maintenance
-Resistant to weathering and pests
-Can be stained or painted to match your home’s exterior

-May dent more easily than steel doors
-Not as energy efficient as steel doors

Steel Doors
Steel doors are made from…you guessed it, steel! They are often used in commercial buildings because they are incredibly durable and low maintenance. Steel doors can also be insulated to improve their energy efficiency. However, they are more susceptible to rusting than fiberglass doors.

-Very durable
-Low maintenance
-Can be insulated for improved energy efficiency

Drawbacks: -More susceptible to rusting than fiberglass doors

Fiberglass Doors

Fiberglass doors are made from, well, fiberglass. They can be either hollow or solid, and they’re usually insulated. Fiberglass doors are also low-maintenance and can withstand harsh weather conditions.

Pros of Fiberglass Doors

There are many benefits that come with choosing a fiberglass door for your home. Fiberglass doors are:
-Resistant to rotting, warping, and splitting
-Low maintenance (they never need to be painted or stained)
-Impact resistant
-Energy efficient
-Available in a variety of styles to complement any home

Cons of Fiberglass Doors

Fiberglass doors have a number of advantages over steel doors, but there are a few potential disadvantages to be aware of as well. Fiberglass doors can dent and scratch more easily than steel, so they may not be the best choice if you have young children or pets. They also tend to be more expensive than steel doors, although the price difference has decreased in recent years.

Steel Doors

If you’re looking for a new exterior door, you might be wondering if steel or fiberglass is the better option. Both have their pros and cons, but steel doors have a few advantages over fiberglass doors. Steel doors are more durable and less likely to warp or crack than fiberglass doors. They’re also more energy-efficient, which can save you money on your energy bills.

Pros of Steel Doors

There are several benefits that steel doors have to offer. One of the main advantages is that they are extremely durable. Steel doors can withstand a great deal of wear and tear, which is why they are often used in commercial settings. They are also very good at insulating against both heat and cold, which can help to keep your energy bills down. In addition, steel doors are very low maintenance and require little in the way of upkeep.

Cons of Steel Doors

There are a few potential downsides to steel doors that you should be aware of before making your final decision.

First, steel doors can dent and ding more easily than fiberglass doors. This is because fiberglass is a softer material. So if you’re looking for a door that will stay looking flawless for years to come, steel may not be the best option.

Second, steel doors can rust if they’re not properly maintained. If you live in an area with high humidity or near the ocean, this is something to keep in mind.

Finally, steel doors can be more expensive than fiberglass doors. So if you’re on a tight budget, fiberglass may be the better option for you.


So, which is better? The answer isn’t as simple as you might think. Both fiberglass and steel have their own set of benefits and drawbacks. It really depends on your needs and preferences as to which one would be the best choice for you.

If you need a door that is energy-efficient, low-maintenance, and can stand up to extreme weather conditions, then fiberglass would be the way to go. However, if you need a door that is more secure and durable, then steel would be the better option.

Both fiberglass and steel doors can provide you with many years of use if they are properly maintained. Ultimately, the decision comes down to your own personal needs and preferences.
