Between Low-E and Window Film; Which Is Better?


Tinting your windows today isn’t negotiable. Window tinting offers a wide range of benefits that protect your property, health, and finances.

But, when it comes to deciding which window tint to use, you may wonder which option is the best for you. Low emissivity or Low-E window tint is a type of glass film that many property owners are using today. Although it is more expensive, it offers a better return of investment compared to other films for windows.

Low-E glass windows increase a home’s value and fix drafty windows. But, sun-blocking window films also have benefits that you may want to consider. For instance, they are a quick and low-cost solution for reducing UV rays.

If you’re deciding between low-E glass windows and window films, this guide can help you make an informed decision.

Benefits of Low-E Windows

Low-E films are built-in permanently to windows. They are designed to filter out long heat wavelengths while allowing short heat wavelengths to pass through. Thus, if your windows are tinted with an e-film, they’ll block out UV infrared light. This window film increases energy efficiency in your home without blocking your view from outside. Also, you can enjoy sunlight as it allows it to penetrate through. According to EPA, low-emissivity windows prevent heat loss by as much as 50%.

Low-E films are also durable and reduce the cost and effort of cleaning windows. That’s because they repel water particles, dirt, and sand from sticking to your glass. Again they reduce condensation and protect against UV damages.

Why You May Have Second Thoughts about Low-E Windows

The cost is expensive. It ranges from $300-$1000 per window. Therefore, it’s not a suitable option for those on a tight budget. The installation is also costly compared to normal glass. And you may also need to upgrade all your windows. Otherwise, the final look won’t be that uniform. Note that upgrading one window may not be that efficient. Also, the view can be mild hazy, although most people say that it’s not noticeable.

Perks of Window Film

If your budget is tight, a sun-blocking window film to reduce heat can be your best bet. The cost ranges between $6-$14 per square foot, making it affordable. Also, you don’t need to cover all windows or remove or replace them. You can pick which windows to tint and tint them as they are. However, they’re not a very durable solution. After some years, you may notice peeling. Also, it darkens your view and can make your windows appear shiny.


Additionally, if the problem leading to heat loss is window fit, installing a window film won’t fix it. Plus, while it doesn’t need window replacement or removal, you may need to fix drafty windows to get maximum benefits.  Also, you risk voiding the window manufacturer’s warranty if you install an aftermarket film.

Low-E Windows VS Sun Blocking Window Film

Older homes may not benefit from a window film as it may not be effective in lowering energy bills. Low-E films are the best alternative since they are more efficient.The newer Low-E version comes with a transparent film that minimizes heat while letting natural light in. The only drawbacks are that it is expensive and the warranty isn’t as long.  But, for a new home, the windows are still energy efficient. Therefore, a window film can be the best solution for heat loss.

Final Thoughts

Both low-E and sun blocking window films are designed for tackling energy consumption. The best for you depends on your preference and budget.
