What are Fiberglass Doors?

fiberglass exterior doorsYour entryway door not only keeps out the elements and protects your home from intruders, but it can do wonders for your curb appeal too.

Fiberglass exterior doors are made from a core of rigid insulation, clad with a fiber-reinforced polymer, and covered with an artificial grain to make them look like wood. Manufacturers have gotten so good at mimicking the look and feel of wood that you’d be mistaken for thinking you were handling a solid oak, pine or mahogany door, every time you reach for the handle.

Read on for the other amazing benefits of Fiberglass doors and why they’re a big contender if you’re on the market for a new front door.

Key Benefits of Fiberglass Doors


The polyurethane core in Fiberglass makes it more resistant to damage than traditional wooden doors. This means increased safety and peace of mind.

Fiberglass doors withstand the elements without cracking or bowing. They won’t rust, rot, or warp, and aren’t susceptible to insect infestation or corrosion.

Fiberglass doesn’t shrink or swell like wood, meaning your door won’t get jammed in the summer, or let in the drafts come winter.

Lighter than steel, Fiberglass’ light weight reduces tensile stress on door hinges, giving you a door that will continue to open and close without sticking or binding.

2)Low Maintenance

Fiberglass doors look clean and new for longer and require little to no upkeep. Regular cleaning with a damp cloth should be sufficient.

If your door faces the beating sun, or has a dark finish, a restorative coat of clear marine varnish can protect it and keep it looking fresh.

3)Energy Efficiency

Fiberglass doors offer up to four times the R-Value (professional insulation rating system) than wooden doors.

They feature fully insulated cores designed to reduce thermal transfer between outdoors and inside, giving you better protection against cold and heat.

With a Fiberglass door, you’ll be able to use less energy to keep your home at a comfortable temperature and can help save money on your bills.

The solid construction and quality hardware of a Fiberglass door makes it more secure than a wooden one.

Reinforced steel plates reduce the possibility of forced entry when the door is locked or closed, and other added safety features such as an extra deadbolt make it one of the safest options out there for you and your family.

5)Quality Designs

Your front door speaks volumes about your style and personality. Fiberglass doors come in a wide range of design options to suit every taste and budget.

Choose an authentic woodgrain texture or a multi-coat factory prefinishing option for a smoother and sleeker look.

Incorporate windows with glass options ranging from clear to highly ornate. Add the perfect finishing touches like a wrought-iron grille or knocker to create the door you’ve always wanted.
