For an expansive collection of window glass options, it’s time to call NEXT Door & Window. We’re dedicated to offering the highest quality window options available. From top-notch energy efficiency and superior insulation to decoration, our Design & Energy Experts help you find the perfect fit for your home’s comfort, energy, and style needs.

Unique & Stylish Window Glass Options

As clear-cut glass can appear, there is much more to it than a simple surface look. Glass plays a vital role in your home’s comfort, energy efficiency, design, and even security. With a huge selection of different high-performance glass types to choose from, it is essential to find the ideal one for your home.

The Design & Energy Experts from NEXT Door & Window are here to guide you through a wide selection of glass options.

Whether you need replacement glass with reduced glare, enhanced privacy, or improved noise reduction, we help you find glass that not only looks great but also works even better.

Decorative Glass

For homeowners looking for that one-of-a-kind look for their windows, decorative glass is the ideal selection. This glass is specially designed with a choice of designs and patterns, providing obstructed views.

Insulated Glass

Insulated glass utilizes two to three separate panes that are divided by a spacer bar. Between these spaces, an inert gas like argon is used for enhanced insulation, improving overall home comfort and energy savings.

Tempered Glass

These glass types undergo a heating or chemical tempering process to enhance their overall durability and resistance. When broken, tempered glass breaks into larger, dull pieces, rather than shattering into tiny fragments like other types, making it ideal for safety and security.

Tinted Glass

A type of decorative glass that uses a thin, slightly colored layer between its glass panes. The colored layer blocks out harmful UV rays while reducing heat gain in your home, improving overall energy efficiency, and lowering costs. We can refer you to a local company that specializes in tinted glass.

Laminated Glass

This glass type is made with multiple layers of glass bonded together, along with a clear underlayer. Once bonded, the underlayer will hold the glass in place, so if impacted, the broken pieces are held together. This reduces the risk of injury compared to typical glass types, which shatter and scatter upon breaking.

Double Glazed Glass

Double-glazed, also known as double-pane, windows are designed with two sheets of glass separated by an insulated air space. The space in between is filled with an inert gas, which increases the overall energy efficiency while also reducing noise and condensation.

OITC/STC Glass

Outdoor-Indoor Transmission Class (OITC) and Sound Transmission Class (STC) are specifically designed glass types that are designed for noise reduction. The design utilizes thicker glass panes to minimize the transmission of outdoor noise into the interior.

Annealed Glass

Also known as standard glass. These are the most common types of glass that undergo a slower cooling process after being made. The controlled cooling allows for the material to become more resistant to breaking.

Low-E Glass Options

When shopping around for new replacement glass windows, you may have come across the term Low-E glass. The E stands for emissivity, which indicates a material’s ability to radiate energy. This glass is made using a nearly invisible, thin metallic coating that helps control heat transfer.

This technology not only blocks out incoming heat from the sun’s UV rays during the summer but also redirects heat back into your home during the winter months. This means better thermal insulation, enhanced indoor comfort, and can even reduce your heating and cooling bills.

Below are the available levels of Low-E glass options at NEXT Door & Window:

Low E1 Glass

Best suited for colder climates, Low-E1 glass facilitates more effortless heat transfer into rooms. At the same time, the glass will also block heat loss, allowing any room to retain a consistent warm temperature.

Low E2 Glass

The Low-E glass provides exceptional performance for moderate climates. Low-E2 counters direct summer heat, blocking 84% of UV rays, reducing heat transfer into the home. When temperatures start to drop outside, the glass retains heat indoors, keeping your home warm and cozy.

Low E3 Glass

For homeowners in the hot and sunny climates, Low-E3 is the glass for you. This glass contains glazing that rejects solar heat and even blocks up to 95% of the sun’s UV rays. But don’t worry—the glass allows natural light to come through and brighten up your space.

Low E3/ERS Glass

Designed for use in any climate or conditions. The glass is equipped with an additional roomside metallic coating, reducing heat loss, providing maximum energy efficiency, and improving overall comfort year-round.

I had a very positive experience working with Next Door from the initial sales meeting through installation. This is my second experience working with Jason and the installation teams. The Marvin Signature windows are great and the installation team was fantastic. Their attention to detail and the care they displayed was amazing. Based on their high level of workmanship, respect for the house, and the manner in which they cleaned up after the job was completed, I would highly recommend Next Door for any window project you need done without hesitation. It was a pleasure working with the entire Next Door team.

We had a fairly small job replacing a front door and reframing two other doors to our courtyard. Although it took a while, the door, which os exposed on both sides, seems to be of high quality with excellent brass hinges and strong framing. We tried and failed to get Lowes, Andersen and other vendors to do the job, but for varied reasons, they refused to quote. Next Door is not cheap,but they did a great job.

We liked the style of our 60-year-old windows but they and the high-maintenance outdoor wood framing needed to go! Next Door consulted with us, measured, and delivered beautiful replacements that perfectly match the look of the old windows but provide an airtight, updated ease of use (and, as we discovered due to a brief but loud construction project at our neighbor's house, a more soundproof quality that is a bonus!). Thanks to our sales contact Luke, lead installer Daniel, and support staff along the way for a great experience.

From initially stepping into Next Window showroom until after our Infinity replacement window install, our experience was amazing! Everything went so smoothly starting with our knowledgeable and helpful salesperson who had exceptional communication. During the entire process any question we had was immediately answered. The install crew was neat, friendly and helpful. The outcome resulted in a quality window with now an updated modern visual appearance. Can’t beat the extended 10 year labor warranty that Next offered as well. We are enjoying our home’s new look!

Below I break down each area with the good and needs improvement. I had to cut my review short because I guess I’m too wordy.

Sales: Zach Tobin was my salesman and he’s a very good salesman. He knows how to do his job and he knows the product. We purchased 12 Marvin fiberglass windows, Provia front door, and a storm door. Yes, he did his job. Products are pricey, but obviously, we agreed to it.
Process up until installation: We had a few other projects going on so we had to wait for the windows to be done. After signing the contracts you get to hear from your project manager and another individual who handles contracts. I assume it’s standard procedure. Didn’t really receive any phone calls, but rather just emails.
Installation: We had our windows installed in February. Unfortunately, that is the time one of our windows needed to go in because of remodeling the inside. I really didn’t want my house opened up to install all 11 windows when it was so cold but, unfortunately, Next stated they had to do it the same day. The installation crew (Greg and his team) arrived on time and were professional and courteous. They definitely knew what they were doing. My only complaint with this installation crew was they took out two windows and then went to lunch before reinstalling. It was about 20° outside. I mean, that is a first world problem considering I have a furnace; they were probably freezing and really hungry. Other than that, I really appreciated their expertise, thoroughness, and professionalism. Fortunately, they were weren’t able to get it to all the windows in one day so they had to come back at a later date to finish installation. They finished the installation of all the windows within 30 days of starting. Fred installed our storm door-he is FABULOUS as well.
Post Installation: I am writing this review and it is September. As stated above, the windows were installed in February. Due to quality issues, we had to have some sashes and frames replaced. In fact, the job is still not done. Still waiting on a few parts to be installed. The customer service post installation has been more than challenging. I send emails, for documentation, which go unanswered. When I speak with someone at Next, I have to explain my situation over again; kind of like they never received the emails. I stopped hearing from my project manager approximately two months ago, and to be honest, I think I only spoke with him on the phone once during this whole process. The lady I hear from the most, Kim, has a tendency to speak over you and doesn’t let you finish what you’re saying. An example of poor customer service with Kim was when we were discussing the pins that hold the window screens in place. These pins keep breaking and I requested additional ones. She requested to know how many I needed and I told her 10, which would be for five windows. She proceeded to tell me that my Warranty is up and I may have to pay for that. I questioned how my warranty is up and she said you’re no longer under warranty for customer service calls. I explained that the push pins are a part and requested the technician bring them when they finish up with the window parts. Not sure if I’m gonna be charged for those yet. However, I did comment on how poorly made the pins are that keep the window screen in place. Kim proceeded to say that’s a Marvin issue and not a Next issue. I was kind of flabbergasted and did tell her “it’s interesting Next stands behind a poor quality product”. She interrupted me to state Next has nothing to do with the pin quality ( she obviously didn’t get the correlation). I then interrupted her and said there’s no need to argue and requested her to follow up with me regarding finishing the windows. Definitely in need a better customer service.
Overview:
Contract signed in late 2024
Installation of windows in February 2025
It is now September and I’m still waiting on finishing the windows due to parts needed.
Would I do it again with Next? No (even though the installation crew was absolutely fabulous)

We ordered windows over 6 months ago after being contacted weekly by a salesman, the process of getting them installed took very long and no one updated us on the process. Mistakes were made that further delayed the ordering process. At the time of installment we noticed the largest window was incorrect and very wrong. The salesmen then proceeded to push me to try and admit that this was a mistake made between miscommunication between my husband and I. This was hugely incorrect as my husband and I were on a three way phone call at the time of ordering. Now they’re having are ordering the correct window, it’s been over a month and barely any updates or communication on when it will be installed. NOW finance is contacting us demanding to begin payments when the project has not been completed. This is a huge headache and we have no one helping us or reaching out.

From start to finish we give Next Door and Window five stars for their outstanding professional service each step of the way. We loved the finished product our new front door with sidelights. It is stunning and just how we imagined it would be when we went through the ordering process with our sales rep. Thank you Next Door and Window for your quality product and team that made it all happen.

We love our new front door with side light and storm door. Everyone was so professional and knowledgeable starting with Gary Armstrong from Sales. He came to our house and educated us on the different doors, had samples of different colors and hardware. After we made our decision he took a picture of our current front door and was able to show us exactly what our new doors would look like on our house so there was nothing left to the imagination. They offer several different options for payment. Our project manager John Nelson kept us updated along the way which was awesome because our door was confirmed to deliver earlier than expected. Installation was booked within two days of our door getting delivered at Next Door and Window. The installers Fred and Mike were right on time, professional and installation was completed perfectly. We highly recommend Next Door and Window and definitely deserve a five star rating! Thank you Next Door and Window!

We needed to replace the last 5 original windows in our 120 year-old home. After much research and numerous conversations with multiple window companies, Next Door & Window of Burr Ridge was our clear choice. From initial contact at the showroom through post-installation, they have consistently been knowledgeable, patient with our questions, thorough, personable, and not aggressive. Customer service was excellent, and the employees are skilled, really nice people.
The installation went very smoothly. The windows were ready at the projected time, scheduling was flexible, and the install itself took ½ day. Cleanup was thorough, and the installers were respectful to us and our home. No stress.
The windows look beautiful, the quality is great, and we are satisfied with the value. We do realize that we need to see how the windows manage seasonal changes.
We dealt primarily with Ron, who co-owns Next Door & Window with his son. Ron is an expert in the window and door business, and the kind of salesperson you hope you get to work with. He was always striving to ensure we were completely satisfied.
It was a pleasure doing business with Next Door & Window.

We had a Marvin Infinity sliding patio door installed by Next Door and Window. Sales rep Zach was good to work with and helped us arrive at a good price. Their showroom has lots of door options to browse through. Installer did a great job in removing the old door, installing the new one and cleaning up. We will go with Next Door for future projects of replacing all our windows with Marvin Infinity. Highly recommend this place for your next window/door project.

We chose Next to replace our front door and side lights. The one being replaced was the original from 1999 and had all sorts of issues. We chose to go with the ProVia 460 Style Smooth Steel entry door and side lights. We opted for full glass on both in order to brighten the entryway. We also did different colors for exterior (black) and interior (white) to fit our styles. The product was built to order so there was a several week delay from purchase to installation but that was expected. Once the materials arrived they delivered it at 8am and the installer worked all day to remove the entire casement and install everything new. It is very high quality. The door is perfectly balanced and hardware aligned to spec!

We absolutely love our new door!

Next Door and Window is definitely a 5 STAR business. Everyone at the office was extremely friendly and very helpful. Ron came out to the house in just a day or two and thoroughly explained and showed pictures of everything we needed to know about doors and storm doors, Next Door and Window also had a top-notch crew install our beautiful doors. I would highly recommend Next Door and Window!

We had two exterior doors and two storm doors installed. I am so happy with our experience with Next. They had excellent customer service from start to finish. The man who came to give us our quote did a thorough job measuring and talking to us about our options. The doors arrived sooner than expected which was a very pleasant surprise. Although it was expensive, I think it is worth it. The only negative is they told us both sets of doors would be installed on the same day with two crews, but unfortunately they sent only one man who had to come two days in a row and worked long hours to get the job done. He also moved our door stopper which left a large hole in our drywall, but didn’t tell us about the damage so now I need to figure out how to fix it.

Next Door and Window replaced an old, rotted exterior door. From the initial sales visit and estimate through installation, they were very prompt and professional. They kept me updated as to the expected installation date and the installation was done quickly and very cleanly. I am 100% satisfied with them and would highly recommend them.

We are very pleased with our Marvin replacement windows from Next Door and Window. The windows are very attractive, interior wood stained to match our existing woodwork and exterior fiberglass with aluminum used to trim out the brick mold. Project was completed on schedule without any problems, so minimally disruptive for us. The installers did an excellent job cleaning up both inside and outside. Highly recommended.

This is our second large project with Next Door and Window. Both projects turned out even better than we expected. We had Next replace all of our doors. They look beautiful and the better seal and outstanding insulation made a huge difference in keeping the house warm in winter and cooler in summer.

Two weeks ago we had Next replace all of the windows. Again, the windows are gorgeous, the installation was flawless and looks beautiful inside and outside. It has definitely improved our curb appeal and the house just looks brighter and sunnier inside. In the current summer heat, we've also already noticed that house feels like its significantly cooler to the insulation and the windows themselves.

Everyone we've worked with at Next has been wonderful. The installation teams were courteous and very professional. They also left our home spotless. When they finished the work you couldn't even tell they were there. The management team also cares--they checked with us multiple times to make sure everything was right.

Next Door and Window is highly recommended! I've recommended them to my family, friends and neighbors.

What is the average cost of replacement windows?

Replacement windows typically cost an average of $200 to $2000 per window. The exact cost will depend on various factors, including the type of glass, the window frame, and labor costs.

What are Replacement Windows?

Replacement windows are brand-new windows designed specifically to fit into a pre-existing opening in a home. They serve as a full upgrade to your current windows, enhancing energy efficiency and comfort, all while providing a fresh, clean look.

How Long Do Windows Last?

On average, windows typically last between 15 and 20 years. As windows age, the built-in seal will begin to weaken, increasing the risk of failure and allowing elements such as wind and water to enter.
