Can New Windows Help You Save Energy?

Have you recently purchased your first home?

As a homeowner, it’s important to look for ways to save money on energy bills. This includes increasing the energy efficiency of your home.

One popular solution is to replace old, inefficient windows with new, energy-efficient ones.

In this article, we’ll provide you with detailed information about how new windows can help you save energy. We also look at what factors to consider when selecting the best energy-efficient windows for your home. Keep reading to learn more.

How Do New Windows Save Energy?

Before diving into the details about how to save energy, it’s crucial to understand how energy-efficient windows work to reduce heat loss in the winter and heat gain in the summer.

Some of the design features that make energy-efficient windows effective include:

Double-Paned Glass

One of the most notable features of energy-efficient windows is double-paned glass. This type of glass consists of two panes of glass with a layer of insulating gas between them.

This insulating gas serves as a barrier, which reduces the transfer of heat and cold through the window, thus making it more energy-efficient.

Low-E Coatings

Low-emissivity (Low-E) coatings are thin layers of metallic oxide applied to the glass that reflect heat and UV rays. They help to keep your home cooler during summer and warmer during winter, thus saving you energy costs.

Proper Installation

Even the most energy-efficient windows cannot save you energy if they are not installed correctly. Professional installation ensures that there are no gaps or leaks around the window frame that can lead to energy loss.

Poorly installed windows can negate the energy-saving benefits of the new windows.

How Much Can You Save with New Windows?

The amount of money you can save on energy costs depends on various factors. These include the climate in your area, the size and type of your home, and your energy usage habits.

Choosing the Right Windows

Choosing the right windows involves considering several factors. These include:

Window Frame Material

Different materials such as wood, vinyl, fiberglass, and aluminum are used for window frames. Each has its pros and cons in terms of durability, energy efficiency, and cost.

Wooden frames provide excellent insulation and are aesthetically pleasing but require regular maintenance. Vinyl frames are easy to maintain and provide good insulation, while fiberglass is a low-maintenance and energy-efficient option.

Aluminum is durable but has poor insulation properties. This can result in higher energy costs.

Window Style

The style of window you choose can also impact its energy efficiency. For example, casement windows provide a tight seal when closed, while double-hung windows may allow air leaks if they’re not closed correctly.

Awning and hopper windows are also energy-efficient as they offer a tight seal when closed.

Energy Star Certification

Windows that are Energy Star certified meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA). Energy Star windows can help reduce your carbon footprint and save money on your energy bills.

U-Factor and Solar Heat Gain Coefficient

U-factor and solar heat gain coefficient (SHGC) are measurements that determine a window’s energy efficiency. U-factor estimates how well the window keeps heat from getting away. SHGC estimates how well the window blocks heat from the sun.

The lower the U-factor and SHGC rating, the more energy-efficient the window.

Other Ways to Improve Your Energy Efficiency

While new windows can help you save energy, they’re not the only solution. Here are some other ways to improve your home’s energy efficiency:

Install Insulation

Proper insulation helps to keep your home warm in the winter and cool in the summer. It also reduces your reliance on heating and cooling systems. You can insulate your walls, attic, and basement to prevent heat loss.

Upgrade Your HVAC System

If your heating, ventilation, and air conditioning (HVAC) system is old or inefficient, consider upgrading to a newer, more energy-efficient model. This can assist you with getting a good deal on energy bills. It will also improve the overall comfort of your home.

Seal Air Leaks

Air leaks can occur around windows, doors, and other areas of your home, leading to energy loss. You can seal these leaks by using weather stripping or caulking to prevent cold air from entering your home.

Use Energy-Efficient Appliances

Replacing your old appliances with new energy-efficient ones can help you save money on energy bills. Look for the Energy Star label. This indicates that they meet strict energy efficiency guidelines.

Maintenance and Care

Proper maintenance and care of your energy-efficient windows are important to ensure their longevity and energy-saving benefits. Here are some tips on how to maintain and care for your energy-efficient windows:


Regular cleaning of your windows helps to maintain their energy efficiency. Use a soft, damp cloth or sponge and a mild, non-abrasive cleaner to remove dirt and grime from the window frames and glass.

Avoid using abrasive cleaners or rough sponges that can scratch the glass and damage the low-E coating.


Regular inspection of your windows can help identify any issues early and prevent further damage. Check for any cracks, gaps, or leaks around the window frame that may compromise the window’s energy efficiency.

Also, check the seals around the window to ensure they’re not worn out.


If you identify any issues with your windows, it’s essential to address them promptly. Small issues, such as a loose seal, can lead to energy loss, higher energy bills, and decreased comfort.

Hire a professional to repair any damage or issues with your windows to ensure they’re done correctly.
