When it comes to choosing your entry door, one of the most frequent questions we get is: what’s the difference between steel and fibreglass? When choosing the right entry system for your home, fibreglass and steel off significant advantages over wood entry doors, which require regular maintenance and lack the energy efficiency of more sophisticated materials. Here’s how each type of entry door is different, and the factors you should think about when choosing the right entry system for your home.


Fibreglass Doors: Fibreglass doors most closely resemble the defined grain of true wood doors. Our fibreglass doors are available in different wood grain textures and over 100 stain and paint options. Fibreglass doors are our most malleable entry option when it comes to designing your door, and have hundreds of glass options available. All Dorplex fibreglass doors are handmade to order, and can be customized by style, colour, and size.

Steel Doors: Steel doors are a more cost effective option for your entryway, but are still aesthetically pleasing. Dorplex steel doors are available in smooth textures and various wood grains. Some of the steel door options come with glass.


Fibreglass Doors: Unlike wood doors, fibreglass entry doors are weather resistant, do not shrink or warp, and are much more resistant to splitting.
