Fiberglass has many attributes that make it a great material for making doors. Some of best features include durability, energy efficiency, and strength. A fiberglass door performs well in any climate and offers looks for every style, from traditional to modern.

Why Consider Fiberglass Doors

Fiberglass doors are two large molded skins with a polyurethane foam core between the skins which is a great insulator against heat and cold. The fiberglass sheets, along with the foam core, do not absorb moisture and therefore eliminate the rotting, warping, peeling, and bubbling that can affect other exterior doors.

Fiberglass doors mimic the grain of real wood doors and can be painted or stained. They are popular for their high insulation values, low maintenance, and resistance to dents and scratches. Premium fiberglass doors are architecturally correct like wood doors.

Advantages Of Fiberglass Doors?

Definis And Sons installs a lot of Fiberglass Doors. We have dozens of styles to choose from. Our showroom in Northeast Philadelphia has many styles on display. Here are some of the advantages of choosing a Fiberglass Entry Door.

Energy Efficient

These doors reduce heat transfer and improve energy efficiency. This can make a big difference in your energy bills as well as improve the comfort by helping to maintain the temperature.


Want the appearance of real wood without the maintenance of traditional products? Fiberglass doors look just like real wood and only the closest inspection betrays the truth. They are classy and elegant, allowing you to make the best first impression possible to anyone visiting your home.

Versatility & Styles

Fiberglass doors come in a variety of sizes, styles, and finishes. You can get them built to fit your opening with a factory finish to match your personal taste. Or you can choose factory-primed doors that you can stain or paint on your own.

Robust Durability

Fiberglass doors work well in almost any climate, even extreme cold and damp conditions. Unlike wood, fiberglass doors do not warp, crack, or rot. And unlike steel, the doors don’t rust, scratch, or corrode. Fiberglass is built to last and will not require yearly re-finishing to stay in top shape.
