FIBERGLASS WINDOWS
Fiberglass windows are a popular choice in Arizona, with thin frames that allow ample light and visibility into the home. While more costly than vinyl, fiberglass windows are impervious to rot and termites, and have a longer lifespan than vinyl windows with impressive durability that withstands decade after decade of Arizona sun.
They are slightly more energy efficient than vinyl, depending on the specific window and energy efficiency features or upgrades chosen, and can mimic the look of wood—a design feature important to some homeowners. Options are also available in a wide variety of style choices, including finished wood interiors.
DunRite Windows & Doors offers a selection of fiberglass windows and doors, and would be happy to come out to your home to provide a free estimate. We’ll share the pros and cons of different window materials, and suggest options that fit your home and budget. Contact us today!

Here’s What Our Customers Say…






































































The installers were efficient and cleaned everything up nicely. Our salesman, Sal, was awesome. He was very accommodating. He answered some questions for me about other windows and doors in my house. He offered my advice on some screen installation. He actually recommended a different type of company to complete the work I wanted done. (just like the movie Miracle on 34th Street). We were not happy with one of the choices we made with the door installation. We thought we would like our choice of framework but did not like the selection once it was up. Even though it was DunRite’s fault, they exchanged the section we were not happy with and did not charge us extra money for their time or the new materials.
I would highly recommend the company.




















“We would recommend him to friends and family in the future. We didn’t require his services for this particular job but his customer care is outstanding!
We called him to replace a window in our home on a Sunday. Not only did he get back to us immediately, he let us know that we contacted the wrong company and referred us to a company that could help us. He explained that if he did come out and do the job he would replace the entire window and what we actually needed was just a glass replacement, saving us a lot of money. He was professional and very easy to deal with.
Even though we didn’t use him – based on his integrity, professionalism and customer care, we would recommend him in the future.”
What is Fiberglass?
Fiberglass windows are made from a blend of polyester resin and glass fibers that can be shaped and molded, even stamped to look like wood.
Made from approximately 60% glass and recyclable when removed, fiberglass windows are an environmentally friendly choice. A strong, durable material that won’t bend or dent, fiberglass windows resist termites, water damage, corrosion and rotting. It also has minimal expansion or contractions from weather, and can withstand even the most extreme heat.
Options range from basic fiberglass windows, where the entire window or door frame is extruded fiberglass, to mid-range doors and windows that have a thin layer of fiberglass wrapped around a wood core, and higher-end windows that have the glass fiber pulled through a resin bath and a heated die, then topped (or clad) with an exterior thin layer of another material, such as aluminum, Fibrex or vinyl.
Many manufacturers include proprietary compounds in their fiberglass mix to extend durability and/or energy efficiency.
