Window film helps with energy efficiency in two ways: It rejects solar heat. Window film rejects the heat from the sun, preventing it from entering into a space through the windows. It retains heat. When window film is applied, it seals up windows, improving insulation to retain heat indoors in the winter, while still rejecting heat in the summer.

Windows Welcome Sunlight-And Uncomfortable Temperatures

While windows are considered an architectural necessity in both homes and offices, they can dramatically impact interior temperatures. For instance, on a hot, sunny day, the sun through windows can bring with it uncomfortable hot spots, causing interiors to heat up and HVAC systems to burn through energy. On the other hand, in the winter, windows without window film may have difficulty retaining heat indoors. These inefficiencies not only cause uncomfortable temperatures, but they can also be harmful to HVAC systems. HVAC systems have to work harder to maintain the desired temperature, resulting in excessive wear and tear, and in turn, higher energy bills. Luckily, 3M offers numerous window film products that can improve the energy efficiency of your space without replacing your windows.

3M Thinsulate Window Film

3M Thinsulate Window Film provides improved insulation to both homes and offices. Additionally, its neutral appearance helps to maintain the look of existing windows. This low-emissivity window film can improve the insulation value of a single-pane window to that of a double-pane, and a double-pane window to that of a triple-pane. By improving insulation, this window film keeps heat out in the summer, while retaining heat indoors in the winter for improved comfort year round. In turn, energy efficiency will be improved and energy bills will drop. In addition to its insulating abilities, Thinsulate film also rejects up to 99% of UV rays.

3M Daylight Redirecting Window Film

3M Daylight Redirecting Window Film is designed to redirect the sun’s light deeper into the room to increase the amount of natural light within a space. This film is installed to the upper portion of a window, and daylight is redirected up towards the ceiling so it can reach further into a home or office. Its ability to redirect over 80% of the sun’s light reduces the need for artificial light, and in turn, cuts energy consumption and improves efficiency. Not only will this film help to achieve improved efficiency, but the natural light it provides will also create a more pleasant environment for occupants.

3M offers a variety of window film solutions that improve the energy efficiency in commercial and residential spaces. From improved insulation to redirected sunlight, our team members will help you discover the perfect window film solution for your space
