Steel vs. Fibreglass Door: Which Is Best for Your Home?

When you choose a door, you probably decide based on which one you like the best. Picking an entry based on aesthetics is fair; you don't want to be stuck with an entryway you don't like.

But there are other factors to consider when choosing a door, like durability and maintenance. Ideally, you'd have a good-looking door that can offer protection from intruders and the elements.

Steel and fibreglass are two of the most common types of entryways. Read on as we compare a steel vs fibreglass door to find the best choice for your home.


It may come as little surprise that steel is the more durable option. Steel doors can withstand harsh weather conditions with little trouble. Intruders will also have a tough time trying to break through the hard material.

Fibreglass can crack if hit with too much force. The relative fragility of fibreglass makes it a less durable and secure option.

Fibreglass is the longer-lasting material, though. Steel is prone to rusting after some time.


If you want to know how to choose a door for your home, consider picking one that's low maintenance. Luckily steel and fibreglass doors don't require much upkeep.

All fibreglass doors need is the occasional spray with a pressure washer and oiling. You can wipe the door down in between cleanings. You can paint over old worn colours also.

Steel doors require even less maintenance. All these doors require is oiling so they don't rust. You should avoid cleaning them with water to prevent oxidation.

Energy Efficiency

Steel and fibreglass are both energy-efficient types of doors. Fibreglass is a more flexible material that moves with outdoor temperatures, so it is better at keeping climate-controlled air inside the home.

Steel doors warm when exposed to hot weather and transfer heat indoors, so they're less energy-efficient.


When comparing steel vs fibreglass door aesthetics, steel loses. Fibreglass doors come in a variety of colours, grains, and styles. You can make fibreglass look like whatever you want - even wood.

Steel has much less limited customizable choices. You can get steel doors painted whatever colour you want, but you can't repaint them yourself. There aren't as finishes either.

You can get a faux wood finish for your steel door, but fibreglass would look more convincing.
