Energy-efficient windows are ingenious innovations that reduce heat gain or loss indoors, facilitate natural lighting, and offer better insulation than traditional glass panes. The outcome? Decreased reliance on artificial heating or cooling systems and reduced energy bills.
At McClellands Contracting and Roofing, we regularly share our expertise in home improvements to help create a better living environment for our readers and customers. As a window specialist, I am here to help you choose the perfect windows for your home.
In this guide, you will discover the best energy-saving windows, what makes them energy-efficient, and learn how to make the right choice.
How to Check The Energy Efficiency Of Windows
When installing new windows or upgrading existing ones, it’s essential to understand the labels or badges shown on them. Contrary to common perception, they’re more than just branding and trademarks. These labels also include details demonstrating the standards a particular window has met through rigorous testing processes.
Should these labels influence your buying decision? On a technical note, yes, they should. So, let’s learn about the labels and technologies underlying the energy efficiency of these windows.
Energy Efficiency Labels and Certifications
Firstly, I want you to pay close attention to a term that regularly appears on window labels: ENERGY STAR® certification. This designation is provided by an initiative backed by the U.S. Environmental Protection Agency (EPA) and the Department of Energy (DOE). ENERGY STAR certified windows meet strict guidelines for superior energy efficiency, helping keep your cooling or heating costs at bay throughout the year.
One rating that reflects the energy cost savings precisely is the Energy Performance Rating, which is offered as part of the National Fenestration Rating Council (NFRC) labeling. These ratings are based on independent tests given by the NFRC and provide homeowners with insights into different energy-efficient aspects of each product.
E Glass Technology
A crucial technology that revolutionized the field of energy-efficient windows is E Glass Technology. You might wonder what “E” is here. It refers to emissivity, reflecting how much heat radiation a window can absorb or reflect.
Low-E glass surfaces have a thin metallic oxide layer responsible for reflecting heat and reducing emissive power at a much higher rate than standard glass.
By using Low-E glass, homeowners can enjoy a significant reduction in their heating or cooling costs while maintaining excellent visibility through their windows. Moreover, it also filters out harmful UV rays that may fade your furniture over time.
Single-Pane Windows vs. Double-Pane Windows
Let’s talk about another innovation: pane counting. When considering window replacement, you’ll encounter terms like single-pane, double-pane, and perhaps even triple-pane windows.
Single-pane windows consist of just one sheet of glass, meaning they lack insulation against outside temperatures when compared with double or triple-pane versions.
Double-pane windows come with two sheets of glass separated by an insulating gap filled with argon or krypton gas. These form a shield against the transmission of cold and hot outer temperatures indoors.
Therefore, installing double-pane windows proves cost-effective on a few levels. You benefit from smaller utility bills due to less strain on your HVAC system, plus greater indoor comfort during extreme weather conditions.
U-Factor and SHGC Ratings
Lastly, let me introduce you to U-factor and solar heat gain coefficient (SHGC) ratings.
The U-factor represents the rate at which a window conducts non-solar heat flow. The smaller the U-factor, the more energy-conserving the window. It usually lies in the range of 0.2 to 1.2.
SHGC signifies how well your window blocks heat caused by sunlight. Lower SHGC values are ideal for warmer climates as they trap less solar heat, while higher SHGC is perfect for colder areas as it can help warm up interiors using natural solar warmth.
By finding the right balance between these ratings based on your home’s location, you can make an informed choice and buy a stellar set of energy-saving windows!

Installation and Placement Strategies To Maximize Your Window’s Energy Efficiency
Here are the best strategies that you, as a homeowner, can utilize to benefit fully from your new energy-saving windows.
1. Window Placement
Understanding the orientation of your home is essential in installing windows effectively. In general, windows facing north could let in less heat and glare, leading to potentially lower heating expenses during winter months. Moreover, south-facing windows are beneficial in colder climates as they allow more sunlight (and therefore warmth) to enter during winter, while in sunnier climates this might cause overheating issues in summer. To avoid such problems, consider applying window treatments or covers like blinds or films that offer solar control.
2. Shading Requirements
Installation without considering shade would result in inefficiency regardless of how advanced your energy-efficient window is. Particularly during sweltering summers, strategic placing of shades over windows could save significantly on air-conditioning costs.
For instance, overhangs placed correctly above south-facing windows deflect high-summer sun away, keeping interiors cooler, leading to less reliance on air conditioners and thus reducing energy use significantly.
3. Window Size
Don’t underestimate the impact of window size on energy efficiency. If a window is too large for its placement area, it may lead to quicker heat gain or loss despite having superior insulation properties due to greater surface area exposure.
The correct sizing according to your climate zone with the most suitable glazing should be considered carefully with help from building professionals or thermal performance assessors before the installation process begins.
4. Choose The Right Contractor For Window Installation
Look for window companies with a track record of success in installing high-quality windows. Check for manufacturer certifications or accreditations that demonstrate their expertise and workmanship assurance.
By executing these effective strategies along with picking top-quality energy-efficient models, you’ll maximize both monetary savings and environmental benefits. Remember, every little step counts on your journey towards sustainable living.
One more aspect is windows, like any other investment made in your home, need proper maintenance so that they function optimally and last longer.
Maintenance and Care Tips For New Windows
Here are some crucial care guidelines that can go a long way:
Cleaning & Inspections
One of the most basic yet significant steps to maintain your windows is to clean them regularly. Dust and dirt build-up can drastically affect their efficiency over time. Make sure you clean the window sills and tracks as well because neglecting these areas can lead to moisture issues, which might damage the frame materials.
Checking your windows from time to time for marks or framing issues is another critical step. Such flaws may not seem important initially but will eventually compromise thermal efficiency if left unchecked.
Correct Window Operation
If your windows are designed to slide, it’s important not to force them open or close. Rough handling can damage the mechanisms and seals, compromising their ability to insulate and protect your home. Instead, take care to operate them gently and smoothly, following any instructions provided by the manufacturer. By using your windows correctly, you can prolong their lifespan and maximize their performance for years to come.
Maintain the Quality of the Caulking
Lastly, maintaining the quality of the caulk or sealant is crucial for energy-efficient glass panes. Caulking protects the windows against unwanted drafts entering the home, providing an extra layer of thermal insulation. Always keep an eye on deteriorating caulk and replace it immediately when needed.
