What are fibreglass garage doors?

Popular for their innovative design, fibreglass garage doors are manufactured with a woven glass thread combined with resin and then connected to a metal chassis. 

They typically feature wooden moulds which give the door the graining and texture of real wood – this provides a sophisticated and authentic look without the need for regular maintenance. 

Advantages of fibreglass garage doors

There are a wide range of advantages to having a fibreglass garage door installed at your property. These include:


Fibreglass is one of the most lightweight materials when it comes to manufacturing garage doors.

This means it weighs less than other materials, therefore placing less strain on door openers, springs and motors. With this in mind, they offer greater longevity as they will require fewer frequent repairs or replacement of parts.

Low maintenance

Another reason why fibreglass garage doors are highly sought after is due to their low maintenance qualities.

While they often take on the appearance of wooden doors, they do not warp, shrink or twist like wood sometimes can.

Instead, a simple wash with water is all that’s required to keep the surface clean. 

Strong and secure

Many people seek security to keep their property safe when selecting a garage door.

When opting for a fibreglass product, this security is assured. This is because fibreglass garage doors are well-known for their strength and durability, giving you peace of mind that your building is protected.  

Furthermore, they’re a great choice for coastal locations as they can withstand harsh weather conditions while not compromising their reliability or strength.  

Stylish appearance

In addition to all of their practical benefits, fibreglass garage doors also offer a wonderful aesthetic appeal.

When paired with a faux wood look, they offer the stylish, sophisticated look that is commonplace with timber doors, while maintaining functionality.

What manufacturers sell fibreglass garage doors?

While the popularity of fibreglass garage doors is certainly on the rise, not every manufacturer sells them.
