Frequently Asked Questions

My Local Big Box Store Sells Replacement Windows. Aren’t They All the Same?

Wall of Windows - Advanced Window Products

Not even close! Replacement windows from local home and garden stores are generally a low-quality replacement window. Local hardware stores carry often only carry windows for people looking for the cheapest window available. However, if you are looking for an energy efficient window to help decrease energy costs of your home or a triple paned window to keep street noise out – Advanced Window Products is your go to! We manufacture all of our replacement windows in our Salt Lake City warehouse with the highest quality materials available.

Another downside to buying replacement windows from a hardware store is that they come in standard sizes, and you may need to modify your home for the new window, which can be costly. On the contrary, Advanced Window Products will send a window professional out to your home to carefully measure your existing windows in order to manufacture the perfect sized window for optimal performance.


Why Does Condensation Form on a Window?

At the edge of most insulated glass units, there is a metal spacer which gives the unit its structural stability. The metal connection  permits heat loss by conduction, up to 120% faster than the center of the glass. We choose to use a Warm Edge Technology known as XL Edge because it eliminates condensation, as well as increases the seal of the glass unit five times more than a metal-sealed unit. See more reasons why it might be time to replace your windows here.


Will I See an Increased Level of Comfort and Savings in My Home with Double-Pane Vinyl Windows?

Yes! In fact, most people have experienced a dramatic,  25% energy savings.


Why Should I Order Custom-Fit Windows for My Home?

Because all window openings vary in measurement (due to settling or unsquared window openings). We custom make each window to ensure a perfect fit. Call 1-800-505-9622 for a free estimate. See other reasons why it is important to have secure and safe windows here.


New Sliding Glass Doors - Advanced Window ProductsWhat is a Replacement Window?

A replacement window is a window that has been custom built to fit the dimensions of an existing window. Advanced Window Products offers a wide array of windows styles and colors of replacement windows to compliment any homes’ architectural style.


What Advantages Do Vinyl Windows Have Over Aluminum?

If your existing frames are made of aluminum or steel, you are losing most of your energy through the frame. Metal acts like a magnet, drawing heat and moisture to your glass and window sill, losing energy and in some cases attracting mold and mildew to clean up.


Do Replacement Windows Have to Be White?

No, replacement windows do not have to be white. We have tan and almond color vinyl offerings, as well as a variety of colors that can be applied in a special painting process. See all the window frame color options here.


Will Replacement Windows Really Pay for Themselves?

Replacement windows have a great ROI. If you select high-quality, energy-efficient windows, your windows will get a return on your investment in savings through lower heating and cooling bills. Engineered and well-built windows have been proven to lower home energy consumption by 30-40%.


Does Advanced Windows Offer Window Privacy Glass Options?

We offer 3 different obscure glass options for those cases when extra privacy is needed, such as for a bathroom window. The different types of privacy glass you can choose from includes standard, rain drop, or glue chip privacy glass windows.


Gables with New Replacement WindowsWhat are the Benefits of Buying My Windows Straight from the Window Manufacturer?

There are three reasons. First, you will save time by bypassing the middleman. Second, you will receive a quality installation by factory-trained installers. And third, you will receive the peace of mind of knowing that your Lifetime Guarantee is backed directly by the factory, and not by a dealer who may not have the same longevity, or who may pass the warranty responsibility on to an out-of-state factory. Call today for a free in-home estimate at 1-800-505-9622, or fill out our no hassle form to the right.


How are Advanced Window Products Tested and Certified as Energy Efficient?

Our products go through rigorous testing regularly by the NFRC, to ensure their energy efficiencies meet the standards. The NFRC supplies the stickers that come on our products and show the ratings.


How Can I Prepare My Home for My Replacement Windows?

Preparing your home for replacement windows is as easy as 1-2-3:
1. We ask that you take down any curtains, blinds, or other window treatments.
2. Security devices on windows should be removed and turned off by your security company.
3. Please allow a clear path to the windows being replaced.


How Long Will It Take to Get My Replacement Windows? How Much Time Should I Allow for the Installation?

The demand for windows varies throughout the year based on weather and other factors. Your order could be fulfilled anywhere from 2 to 8 weeks from purchase. This is a question for your estimator to get an accurate expectation for your order timeline.


Does Advanced Window Products Install Replacement Windows Year-Round? If So, Will I Lose a Lot of Heat/Cooling at the Time of Installation?

Advanced Window Products installs new and replacement windows year-round, rain, shine or snow! We seal off the room, and then remove one window at time. This allows us to keep as much heat/AC in the home as possible; it works very well. PLUS the energy savings from your new windows will make up any costs incurred during the window installation process many times over!


What Happens to My Old Windows?

We will haul away all the old windows and debris. We will recycle anything that can be, and dispose of the rest of the waste for you.

We recently had new windows installed and the difference has honestly been incredible. The first thing we noticed was the noise reduction. We live close to two major roads, and traffic noise used to wake me up constantly throughout the night. Since installing these windows, it’s amazingly quiet inside the house — I can barely hear anything outside now. That alone has been life-changing for us.Beyond the sound reduction, the windows completely upgraded the look of our home. They feel modern, high-quality, and extremely well made. The value for the price was excellent, especially considering how much they improved both comfort and appearance.We’ve also noticed a huge difference in temperature control throughout the house. Rooms stay much more comfortable, and the home feels far more energy efficient overall. The house maintains temperature better and feels less drafty no matter the time of day.Overall, we could not be happier with the investment. The combination of appearance, quality, energy efficiency, and especially the noise reduction exceeded our expectations. - 5/12/2026

If you are on the fence about using Advanced Windows, go ahead and take the leap. The entire experience was seamless and professional. Mason was our initial sales contact. He was never pushy but he simply gave us the facts and let us ask the questions and do the research. He gave us a list of nearby addresses of customers. We drove by each one and even rang doorbells. Yes we sure did! All were happy with their choice and the windows are beautiful. They use argon gas in between panes and you really notice how the transfer of heat is stopped in the Arizona sun. Truly a game changer. The windows are manufactured by the same company used by the higher end companies but at a much more affordable cost. Life time warranty to boot.The installation team was outstanding. I asked for their names because they deserve a shout out Francisco,Mario,Julio,Saul and Martin. If you can, ask for them by name. They were professional, knowledgeable,detail oriented,courteous and clean. No mess. The company got our windows done in 1 day which is mostly due to this team’s hard work and due diligence. I will recommend this company to anyone! The windows work effortlessly and really add to the appearance of our home. I have no doubt the was one of the best decisions we have made to add value to our home. - 5/11/2026

My windows are beautiful that I got from Advanced Windows. Dallin helped me order my windows and he was amazing to work with. So professional and helpful. Gasson and his crew are second to none. You definitely want them when it comes to installation. They are perfectionists and will make sure everything is the exact way you want your windows to be. Grace in the office is kind and on top of scheduling all of the appointments. I would definitely recommend Advanced Windows if you are thinking about getting new windows. - 5/11/2026

From the first meeting where we discussed the product and price to the installation the whole Advanced Windows team was excellent. The price was great, the product is great, and the fact that they manufacture locally means I'm not worried about them being able to make good on any warranty issues. I recommend them wholeheartedly and would use them again. - 5/08/2026

It was great working with Advanced Window Products. The 0% finance and over all cost of our 15 windows was the lowest price out of 4 other companies.Installation was fast and easy only taking 2 days. We had a few issues and the team came back is fixed them in less than 1 hour. All our windows work great and we can feel the difference already.Looking forward to see how well the windows perform in summer - 4/16/2026
