Your front door is your home’s first impression. For many homeowners, this is reason enough to consider upgrade options for their exterior door. The right door can transform the look of your home and enhance curb appeal. If you’re thinking about upgrading your own, you’re probably in the middle of a lot of research.  
We know, it can be overwhelming. 
Between the door material, glass options and which style door complements your home’s architectural style, there is a lot to think about. At Masonite, we want to make the process easier for you. In this article, we discuss more about fiberglass doors, including what exactly they are and the reasons why choosing one for your exterior should be top of your list. 

What is a fiberglass door?

Fiberglass is a type of plastic that is strengthened with glass fibers. Fiberglass doors generally have two layers of fiberglass skin: an insulated foam core and a thick polyurethane frame. 
Fiberglass doors are a popular front door option because of the various benefits they bring to a home. At Masonite, we have a wide range of styles, designs and finishes to suit your personal preference and home’s architectural style. 

4 reasons to select a fiberglass exterior door

Read more about why fiberglass is a perfect choice for your exterior door:

1. Greater durability

Fiberglass doors are more durable than wood and steel doors, and are resistant to harsh weather conditions, like humidity, cold, rain and heat. They are also less likely to warp, rot, rust or expand, with an additional benefit of being resistant to dents and scratches. This means your door will look great longer.  

2. Lower maintenance

Compared to other materials, fiberglass doors require minimal maintenance. They do not need regular painting or staining and can be easily cleaned with mild soap and water. A fiberglass front door finish maintains its appearance over time with far less upkeep than other door materials.

3. Better energy efficiency

Fiberglass doors offer excellent insulation benefits to keep your home comfortable. They typically have a higher insulation rating than wood and steel doors, so they reduce heat transfer and energy loss. A well-sealed exterior door that keeps out wind and rain is critical to further reduce energy consumption and maintain your home’s comfort. What’s more is that many fiberglass doors come with an ENERGY STAR® rating, which can sometimes include tax and rebate incentives.

4. More design versatility

Fiberglass doors come in a wide range of styles, designs and finishes. They can closely mimic the look of wood, including wood grain textures and stains, giving you an appealing and authentic appearance without the upkeep of a traditional wood door. They also come in dozens of style and glass options to match any home or personal style.
