What Makes a Window “High Performance”?
By: Architectural Visions
If you are adding new windows to a home or replacing current windows, it makes a lot of sense to choose the best quality products that will last a long time. But only some windows are considered to be “high performance,” which is a designation that’s worth learning more about as a homeowner.
Here is an explanation of what high performance windows are and the various factors to consider when choosing them for the rooms of your house.
How Windows Perform Highly
High-performance windows may also be referred to as advanced window technology, high-efficiency windows, or enhanced comfort windows. Compared to traditional windows, high performance windows are designed to make you more comfortable in your home and conserve energy. These windows excel in the categories of energy efficiency, noise reduction, and durability. High performance windows also help minimize the effects of the sun and keep you cool inside on even the sunniest of days.
When you choose high performance windows for your home, you can feel confident that you’re getting the best of the best with your upgrade.
Standards of High Performance Windows
In order for a window to be classified as high performance, it must meet or exceed certain criteria for excellence. To evaluate a window’s performance, you can refer to the federal government’s that rates windows for their energy efficiency. Almost all Marvin windows meet or exceed Energy Star standards because they have passed rigorous performance tests that are conducted by third-party reviewers. According to the U.S. Department of Energy,
If you’re looking for high performance windows, also look for a label on the product. This is an independent organization that tests and rates windows to give you a better idea of how a window will perform after it is installed in your home. Many of the windows that we sell at AVI Windows & Doors have NFRC labels, which we can tell you more about and explain the ratings when you visit one of our locations.
Meanwhile, U-factor is a measurement of how much heat energy is gained or lost. This is another standard for high performance windows to consider. A low U-factor is better than a high U-factor for saving energy. Also, SHGC (Solar Heat Gain Coefficient) is a measurement of how much solar radiation comes in through your windows. A lower value SHGC is desirable for windows to keep more of the sun’s energy out of your house and lower your summertime cooling costs.
If you are interested in buying high performance windows, it’s a good idea to buy them from a company that specializes in this type of product to ensure that you get what you’re paying for. AVI Windows & Doors is an EPA Lead-Safe Certified firm, our Atlanta location has earned EarthCraft Light Commercial certification, and our experts are trained in environmentally sensitive practices too.
Benefits of High Performance Windows
There are many reasons why homeowners choose to have high performance windows installed in their homes. Here are some of the top benefits of high performance windows and why you might want to consider them for your next project.
- An eco-friendly choice with high energy efficiency
- Save money on your monthly energy bills

- Tight seals to reduce air leakage
- Feel more comfortable on hot and cold days
- Beautiful, timeless design that you’ll love for a long time

Styles of High Performance Windows
Something else to know about high performance windows is that the style of window you choose impacts its level of performance. Due to their construction and functionality, some styles of windows are simply more efficient and durable than others.
For example, Marvin’s Ultimate Casement Windows have very high efficiency and are considered high performance because they have multipoint locks that seal very tightly to keep inside air in and outside air out. This is important on hot and sunny days when you’re trying to keep your home cool and also on cold winter days when you have your heater running indoors.
Other styles of windows that are generally very energy efficient are picture windows and special shape windows. As long as these windows are properly sealed, these windows are great options because they don’t typically open up and therefore don’t allow air drafts to flow in. Many double hung windows that we offer at AVI Windows & Doors are energy efficient too because of their advanced design improvements and excellent craftsmanship.
Materials Used for High Performance Windows
The types of materials used to create a window affects how high performance it is as well. If you want great performance, consider tri-pane windows with krypton gas between the layers of glass for awesome energy efficiency. Krypton helps control temperature extremes, while three layers of glass saves more energy than just two layers of glass.
Marvin is a great brand name to know for high performance windows because of the insulating glass these windows have with their multiple panes. Additionally, Marvin window frames are made with advanced materials to reduce air leakage and increase efficiency for many years. Wood is a great insulating material and a classic choice for windows. Aluminum cladding can be added to windows to add extra weather durability.
Another important material used in high performance window is a low-emissivity (Low-E) glass coating that reflects sunlight. This is a great feature to have if you want to prevent your flooring, furniture, and curtains from fading over time due to sunlight coming in the windows.
