When it comes to enhancing your windows and incorporating smart solutions, window film is climbing the charts. Architectural window films were designed to enhance glass performance and are often applied to homes, commercial buildings, and vehicles.

However, it can be quite daunting to find one that suits your needs with all the types of films available in the market. But to help you narrow down your choices, it pays to know the different solar optical properties these films have.

Seeing as window film is extremely beneficial for your space, it’s only right that you understand the solar optical properties to know exactly what you can expect when you have them installed on your windows.


What are the Different Solar Optical Properties?

You need to consider different key elements when choosing the best window film for you. When you know these properties, you’ll find the best type that will suit your property’s needs. Of course, it’s worth checking out credible window film companies to ensure that you’re only getting the highest quality films for your space.


  • Total Solar Energy: This refers to the total energy from the sun that is transmitted through the entire window. It is important to note that this does not consider the window’s thermal or visual properties of the window, so it’s actually the least important of all solar optical properties.
    • Total Solar Energy Transmitted: This refers to the total amount of light that is transmitted through the window
    • Total Solar Energy Reflected: This refers to the total amount of light reflected through the window. This is the most important solar optical property as it is directly proportional to the energy that a window can retain.
    • Total Solar Energy Absorbed: This refers to the total amount of light that is absorbed by the window. This is important to note because it can lead to your room getting warmer.


  • Visible Light: This refers to the amount of visible light that is transmitted through the window. This is also the second most important solar optical property.
    • Visible Light Reflected (Interior): This refers to the amount of visible light that is reflected through the window from the interior. You’ll want to maximise this percentage as it adds to the brightness of the space.
    • Visible Light Reflected (Exterior): This is what’s seen when you’re standing outside, and if it has a higher reflectance value, the more mirror-like your window is.


  • Emissivity: Refers to the film’s ability to reflect infrared energy and how much heat is re-radiated back into the room.


  • Ultraviolet Light Rejected: This refers to the film’s ability to reject ultraviolet light from the sun. The higher the number, the safer it is for your space.


  • Total Solar Energy Rejected: This refers to the window’s percentage rejecting solar energy. This is also known as heat rejection.


The Bottom Line: It’s Important to Choose a Window Film that Will Suit Your Needs

Whether you’re looking for the best window film that will help save you money on your utility bills or you want some added security and privacy, you’ll want to consider the different types of window films that are available.

Seeing as there are many things to consider when selecting a window film for your property or vehicle, it’s crucial that you speak to a credible company to ensure that you’re purchasing high-quality film and that it’s being installed correctly.
