Window upgrades have become a hot topic amongst homeowners looking to improve their energy efficiency. You may be contemplating which type of windows are right for you and your home. We are here to help!
You may have heard the terms single pane and dual pane used while researching windows. Older homes have single-pane windows while others have outdated dual-pane, inefficient windows. You’ve probably wondered “Are dual-pane windows really worth it?” When it comes to upgrading your windows, today’s dual-pane windows are the recommended choice. Single-pane windows are ineffective at reducing heat flow into and out of your home.
If you have been tolerating window problems for quite some time this might be a good excuse to upgrade your windows!
Single-Pane Windows vs. Dual-Pane Windows
Dual-pane windows, also known as double-pane, are made of two panes of glass secured in a single frame. The space between the panes — ranging from a quarter to three-quarters of an inch thick — is either a sealed vacuum or filled with non-toxic argon gas. Argon gas significantly enhances the window’s energy efficiency.
6 Dual-Pane Window Benefits
The type of window you choose can drastically affect your utility bills. According to the U.S. Department of Energy, the heat gained or lost through windows is responsible for 25–30% of residential HVAC energy use. Dual-pane windows have been shown to reduce heat loss through windows by about 50% (New York Times).
Fun Fact: One of the first uses for double-pane glass was for oven doors to retain heat while cooking.
When replacing your windows, look for ENERGY STAR qualified windows, which feature:
- Two panes of glass with argon gas, which dramatically improves the insulation of your home.
- Window frames that are designed to improve the window’s insulating abilities and reduce heat flow.
- Special low-emissivity (low-E) coatings that reflect heat energy either into or out of the home and reduce interior, UV-induced fading by as much as 75%.
The U.S. Energy Department estimates the typical home will save $126–$465 a year when replacing single-pane windows with ENERGY STAR qualified dual-pane windows.
Low-Emittance (Low-E) Glass
Low-emittance (low-E) glass is coated with metal oxides to contain indoor heat while repelling outdoor heat and UV rays. Unlike tinted or reflective glass, which darkens a room, low-E glass allows visible light to pass through easily. Low-E glass is more energy efficient and reduces fading of your interiors. There are different types of low-E glass, so make sure you speak with one of our window specialists about your options.
It is important to pay attention to your window’s U-factor. What is a U-factor? It is a rating system created by the National Fenestration Rating Council (NFRC) that measures the rate of heat transfer from your windows to the inside of your home. Essentially, a U-factor tells you how energy efficient your windows are. U-factor is the opposite of R-value. The lower the U-factor, the more efficient the windows are.
Our dual-pane windows have a U-factor of 0.26. For comparison, a glazed single-pane window has a U-factor of 1.11.
Other NFRC window performance factors are solar heat gain coefficient, air leakage, and visible transmittance. All of our windows meet the California Standard Requirements.
Keep in mind that you won’t experience much energy savings if you only replace one window. You will need to upgrade many windows at a time to experience any significant energy savings.
Don’t lose any more sleep to loud noises outside like dogs barking, highway traffic, or construction. The right windows can significantly dampen outdoor sounds and make your home quieter. Dual-pane windows reduce outdoor noise levels by as much as 75%. In addition to our dual layers of thick glass, our frames are filled with foam for improved noise reduction. Thicker glass panes increase noise reduction by disrupting the sound waves entering the home.

Increased Home Value
Not only will dual-pane windows save you money on your utility bills, they also increase the value of your home. We offer the most exclusive warranty in the industry on our windows. A true double lifetime warranty that is fully transferable to one subsequent homeowner. This means if you replace your windows and decide to sell your home, all warranties will transfer over to the new owner. That’s worry-free coverage for two lifetimes.
Enhanced Curb Appeal
Windows are the eyes of your home; changing their size, shape, or style can give your house a whole new look and feel.
Bell Brothers offers custom, aesthetically pleasing dual-pane windows that make it possible for you to upgrade your current look. For example, you can add bay windows to your home as part of a new window installation. You can even transform an existing slider into beautiful French doors. Dual-pane windows are entirely customizable with the help of a windows expert at Bell Brothers.
Bell Brothers offers a wide variety of window options:
- Double-Hung Windows – slides down at the top and up at the bottom, both sashes move.
- Single-Hung Windows – top sash stays fixed, only the bottom sash can move.
- Casement Windows – attached to the frame by hinges on the side.
- Sliding Windows – slides horizontally from one side to the other in a single frame.
- Awning Windows – similar to casement windows, but hinged at the top.
- Custom Windows – select from a wide variety of types, shapes, glazing, and frames.
Increased Safety & Security
Old, weak, and improperly installed windows present a safety and security hazard to the household. Your windows should easily open and shut without too much or too little resistance. Window locks should work properly and the glass should be strong enough to withstand significant force. Our windows offer a pull-tight cam lock and continuous interlocking rails to prevent tampering with the lock from the outside.
Old window frames are sometimes easier to pry open. Dual-pane windows have heavy-duty frames that are almost impossible to pry loose.
Tempered glass, also known as safety glass, is 4-5 times stronger than annealed glass. The quenching process creates extra sturdy glass, making it more resistant to breakage. If tempered glass does break, the pieces are small, granular chunks instead of long, jagged shards. Think how hard it is to break a windshield. With this type of glass, intruders would have a much harder time breaking in.
Our manufactured Anlin windows and doors earn all three certifications of the American Architectural Manufacturers Association (AAMA) Gold Label. All products pass the Air, Water & Structural, Forced Entry Resistance, and Thermal Performance tests.
Mold and Mildew Control
When your windows are not properly sealed, condensation can form in between the panes and make the windows appear misty or foggy. Often, dual-pane windows use metal spacers, which are notorious for allowing moisture to seep in. However, Bell Brothers uses polymer foam spacers and vinyl framing, which includes an insulating glass sealing system to reduce condensation and energy loss. Additionally, all of our custom windows come with a lifetime guarantee.
Dual-Pane Window Ventilation Concerns
Dual-pane windows will create a tighter, more energy-efficient home, but they will also reduce the amount of natural ventilation in your home. If you are replacing multiple windows with tight, insulated dual-pane windows, make sure you have an HVAC specialist inspect your insulation and ventilation levels.
While modern homes are more comfortable and energy efficient, ventilation and indoor air quality could get compromised. Luckily, the experts at Bell Brothers also specialize in HVAC and IAQ. We will make sure you have sufficient ventilation for a healthy indoor environment.
