Window Materials

At Custom Exteriors, we love helping homeowners choose the best window material that improves their home’s energy efficiency, decreases maintenance costs, and perfectly suits their aesthetic standards. Whether you prefer natural wood or fiberglass we take the guesswork out of the window replacement process and help you make the right choice for your home and budget.

Fiberglass Windows

For homeowners who prioritize energy efficiency, durability, and long-term value, fiberglass is one of the best window material choices available. Fiberglass windows are highly resistant to weather damage, dents, and warping, and they’re easy to maintain with simple cleaning. Their exceptional thermal stability helps keep indoor temperatures consistent, which can significantly reduce energy costs over time. In addition, fiberglass requires fewer natural resources to manufacture than many other window materials, making it a more environmentally responsible option. With a long lifespan and minimal maintenance needs, fiberglass windows offer both performance and sustainability without compromise.

WINDOW TYPES

The type of window you choose can greatly impact the quality, comfort, and safety of your home. Maintenance, security, light quality, and airflow are just a few factors to take into consideration when selecting your window. Rest assured, our team at Custom Exteriors will help you every step of the way. We offer sliders, hung and double hung, picture, casement, awning, bay, bow, and more!

Sliding Windows

Unlike traditional single or double hung windows, sliding windows open horizontally instead of vertically. This makes them one of the easier types to operate and maintain. Depending on your lighting and ventilation needs, sliding windows could be a superior option for your home or business.

Learn More

Single Hung & Double Hung Windows

Arguably the most common window style, Single Hung and Double Hung windows are versatile, stylish, and so easy to maintain. They come in a wide variety of colors and designs and are highly energy-efficient to boot. Single hung windows are defined by a top sash that is fixed in place. Double hung windows, on the other hand, have two moveable sashes.

Picture Windows

Picture windows are a great way to increase your home’s natural lighting. They’re cost-effective, picturesque, and inoperable—making them perhaps the most secure window type available. They’re often chosen because of the completely unobstructed view and natural light that they provide.

Learn More

Casements & Awning Windows

For windows placed in hard-to-reach areas, such as above countertops or furniture, Casement and Awning windows are by far the most suitable type to install. They’re opened by a hand crank typically found at the base of the window, making for easy operation. And because they open completely—unlike other windows that only open halfway—casement windows provide full ventilation for any room.

Bay Windows

Perhaps one of the most glamorous options on the market, bay windows can instantly become the focal point of any home. Made up of three or more panels, they can completely open up a room by letting in large amounts of fresh air and natural sunlight. Solidly built and beautifully crafted, bay windows are slowly becoming a homeowner favorite—even despite their size.

"Loved working with Custom Exteriors. Very responsive to inquiries. Precise in their measurements, estimate and timeframe for completion. Highly recommend them."

Brian I.

"Custom Exteriors provided a great product and good service in replacing 2 sliding glass doors and 2 other windows in my townhouse. One was a custom window that required extra work in refitting the plantation shutters to the new window. Although there were some bumps along the way, Jeff and his foreman Ryan excelled at follow up. I would recommend Custom Exteriors."

"Custom Exteriors did a wonderful job. The installation crew were neat and thorough. My salesman Mark kept me informed about delivery and the windows are beautiful, quiet and warm house. I’m very pleased."

"Kevin one of the owners of Custom Exteriors contacted me the following day and immediately tried to make things right. The first thing, I was impressed about was he took my call without hesitation. Many medium sized business will bounce me around to different people before finally being able to talk to the owner. He was an attentive listener and took to the time understand my needs and wants in an exterior entry door.His communication was top notch, sending me estimates the same day or the following day. He gave me choices in fiberglass doors: ProVia and Therma-Tru, hardware: Trilennium vs Emtek, and single point vs multiple point locks. I just ordered a ProVia doors through Kevin. This surprised both to my husband and me. Before contacting Custom Exteriors, we thought we were going to get a Therma-Tru door, but that totally changed once we the information we needed from Kevin. I get the sense that he truly wants to give customers options and information, but respects the customer's final decision. There is not high pressure sale pitch. Kevin wants customers to be informed and happy with the end product."
