How Do Low-E Windows Work?

In the window world, many terms can confuse the average homeowner. After all, you want to make an informed decision on what goes into your home. That’s why we’re breaking down the science of Low-E windows, a popular window choice in recent years. By the end of this article, you’ll have enough information to decide whether Low-E windows are right for you. 

What does Low-E mean?

Low-E stands for “low emissivity.” In simpler terms, it means lower amounts of heat being radiated. Low-E windows are a game changer in energy efficiency, keeping your home comfortable all year round - not just in the hot or cold months. 

How do Low-E windows work?

Low-E windows work by reflecting and absorbing heat energy. The secret of Low-E windows is in the glass. This glass is coated in a thin, invisible layer of metallic oxide. This coating selectively lets in certain types of light and rejects others. It allows natural light to enter your home, while deflecting UV rays and infrared light, which is heat. 

This is great for keeping your home significantly cooler in the summer. And because they have low emissivity, it drastically reduces the amount of temperature transfer that occurs, meaning your home will stay warmer in the winter. So, with Low-E windows, your home is much less likely to be affected by how hot or cold it is outside. 

The Benefits of Low-E Windows

The energy savings provided by Low-E windows can be significant. Reducing the need for heating and cooling can help lower your energy bills throughout the year, saving you money. Because UV rays cause furniture to fade, the UV protection they offer can extend the lifespan of your furniture and rugs and save you money on replacements.

Using Low-E windows not only benefits your wallet but also the environment. By reducing your energy consumption, you're decreasing your carbon footprint. It's a small change that can make a big difference.

Low-E windows are more of a financial investment than regular windows, so talk to a trusted window manufacturer about the pricing options. Then, you can decide if Low-E windows are a good investment.

Determining If Low-E Windows Are Worth It To You

Low-E windows are great for your home in the long run and make it more valuable when selling. But, they do have a higher price tag than regular windows. Between this and the energy savings they provide, you can decide if they are worth the investment.
