Fibreglass Doors vs Steel Doors: Which is Right for Your Home?

When it comes to choosing the right doors for your home, there are a lot of factors to consider. Do you want something that’s strong and durable or something that’s lightweight and easy to maintain? What about security – is steel the best option for you, or would fibreglass be more suited to your needs? In this blog post, we’re going to take a closer look at both steel doors and fibreglass doors and see how they compare in terms of security, cost and more. By the end of this article, you’ll be able to make an informed decision about which type of door is right for you.


Let’s start with the cost of each type of door. Generally speaking, steel doors are going to be more expensive upfront. However, they are also likely to last longer and require less maintenance over time, so the long-term cost may even out or even become lower for steel doors. On the other hand, fibreglass doors have a lower initial cost but may need to be replaced sooner and require more upkeep.


When it comes to security, steel doors are often considered the stronger option. They can withstand more force and potential break-ins, making them a good choice for homeowners who want added peace of mind. That being said, fibreglass doors can also provide significant security thanks to their reinforced design and technology, such as deadbolts and locking mechanisms. It’s important to note that both steel and fibreglass doors can be further strengthened with the addition of a steel or wooden frame.


Fibreglass doors are known for being low maintenance, as they don’t rust or dent as steel doors can. Steel doors, on the other hand, may need to be repainted or have dents repaired over time.

Climate Considerations

Depending on your climate, either steel or fibreglass could be a better option for your home’s doors. In areas with high humidity and salt air, fibreglass is typically the better choice as it won’t rust like steel can. In colder climates, steel may be a better option as it provides better insulation and can help keep your home warm in the winter.


When it comes to appearance, steel and fibreglass doors both have a lot of options. Steel doors can come in a variety of colours and textures and can even be made to mimic the look of wood. Fibreglass doors also come in a range of styles and can be painted to match your home’s exterior.

Energy Efficiency

In terms of energy efficiency, fibreglass doors tend to be the better option. They offer the ability to work with the weather as they expand and contract, allowing for a tighter seal and better insulation. Steel doors can also be energy efficient, but they may not provide the same level of insulation as fibreglass.


Both steel and fibreglass doors can provide long-lasting durability, but steel is typically considered the stronger option. It can withstand more force and potential damage, making it a good choice for high-traffic areas or homes in rough weather climates.


Ultimately, the choice between steel and fibreglass will likely come down to personal preference. Overall, there is no clear winner when it comes to steel vs fibreglass doors, as they both have their own strengths and drawbacks. It really depends on your individual needs and preferences, so take the time to weigh the factors mentioned above and make the best decision for your home.
