When it comes to replacing a front door, there are two main types to choose from: fiberglass and steel doors. Some homeowners swear by fiberglass doors. Others, however, absolutely love steel doors. So, which one works best for you?

The experts at New Jersey Siding & Windows, Inc. can let you in on a little secret: both types of doors are great options. It all depends on you, your home, and your needs. Here’s a look at some of the advantages each type of door has to offer, so you can understand the differences between them and make the best decision for your northern New Jersey home.

What to Look for in a Replacement Door

All the replacement doors available at New Jersey Siding & Windows, Inc. are made with quality in mind. You can trust that no matter which product you select, you’re getting a beautiful, long-lasting, and secure door that can help keep your family safe. The primary difference between these two types, of course, is the material.

Let’s take a closer look at some of the reasons homeowners might choose one type of door over the other.


The fiberglass doors and steel doors available at New Jersey Siding & Windows, Inc. come equipped with top security features. HOME GUARD doors — which are available at New Jersey Siding & Windows, Inc. — feature exclusive Timberframe all-composite frames. This composite material will not warp, swell, rot, or mold. So, no matter how often it rains, the door’s integrity won’t be compromised by weakening materials.

Timberframe is found in both fiberglass and steel doors, so you’ll get to enjoy this benefit no matter which type you choose. But fiberglass doors take it one step further. HOME GUARD FiberStar fiberglass doors also feature HydroShield technology that repels water away from the perimeter of the door, eliminating the potential for twisting and warping even more.

Some customers want the comfort of a steel door, however, which offers exceptional protection against intruders and fire.

Curb Appeal

Good security is a must, but looks are important, too — your entry door is the first thing guests see when they arrive at your home. If you prefer a more modern, industrial look, you may find that steel doors are right up your alley. With a powder-coat finish and a variety of styles, you can customize your steel door to match your home.

However, if you love the classic wood-grain texture, then a fiberglass door is perfect for you. Fiberglass doors offer the benefit of an authentic wood look, without the downsides of wood like warping or rotting. Plus, they’re available with deep, detailed embossments that can truly elevate your home’s exterior.

As far as color goes, both types of doors are available in a variety of attractive paint colors and stains to suit your needs. Whether you love neutrals or bold pops of color, it’ll be easy to get the curb appeal you desire.

Energy Efficiency

Both fiberglass and steel doors can help boost the energy efficiency of your home. New Jersey Siding & Windows, Inc. doors feature weather stripping, which reduces air leakage and drafts. Steel doors can also have a thermal break between their steel pieces. The thermal break acts as a barrier and prevents home temperature loss. In turn, this makes it easier — and cheaper — to cool and heat your home.

Meanwhile, because fiberglass doors are made with a more flexible material than steel, they’re able to expand and contract along with outside temperatures. The door and the weather work together instead of against each other, resulting in a longer door lifespan.
