What Makes a Good Fiberglass Door

Fiberglass doors are a great investment for your home, but that doesn’t mean you should settle for anything less than the best. Here are the three primary factors that will define the best fiberglass door for you


The desired style of your home is important when defining a good fiberglass door. Some people prefer a modern look and want their doors to match the rest of their home’s decor.

Others prefer an attractive traditional design with lots of light-colored woodwork or stained glass windows. 

You might also consider buying a custom-made fiberglass door that will reflect your unique tastes.


A fiberglass door can be made in almost any size or shape, depending on your chosen style and finish. The standard size is usually 36 inches wide by 72 inches high and typically features a single glass panel measuring 32 inches by 8 inches.

Here are answers to some of the most frequently asked questions about fiberglass doors.

What are the disadvantages of fiberglass doors?

Fiberglass doors are a great option for homeowners who want to save money on their heating and cooling costs, but they have some disadvantages. Here are some of the most common disadvantages of fiberglass doors:

Difficult to open and close – Fiberglass doors can be difficult to open and close due to their weight. The door itself is heavy enough that it’s hard for you to lift alone. You may have to use a tool or get help from another person to open or close the door.

Prone to breaking – Fiberglass doors are prone to breaking because they’re made of glass rather than wood or metal. If you try slamming your fiberglass door too hard, it could break. 

Incompatible with certain types of insulation – You’ll need insulation in your home if you install fiberglass doors because they won’t be able to keep out cold air like rigid wood or metal ones can. 

How much is a good fiberglass door?

Are fiberglass doors better than wood?

Is wood or fiberglass better for a front door?

Wood and fiberglass are both materials commonly used for front doors, but when it comes to durability, fiberglass tends to be the superior choice. Unlike wooden doors, which are prone to moisture damage and rot over time, fiberglass doors are molded without any breaks or seams, making them highly resistant to these issues. Even with regular maintenance, wooden doors will eventually deteriorate due to their natural sensitivity to moisture. Therefore, if durability is a priority, opting for an exterior fiberglass door would be the better decision.
