What You Need To Know About Total Solar Energy Rejected

It can be difficult to fully understand the different types of window film specifications available on the market. Our team of window film experts make sure to provide you with all the information you need to make the decision easier. One of the most important things to know is how much sunlight and heat can pass through a window. We’ll break it down below in an easy way to understand.

What Is Total Solar Energy Rejected?

To determine how much heat a window and window film can block, you first need to check the specifications for what’s known as Total Solar Energy Rejected. Many people think that infrared rejection (IR) and total solar energy rejection are the same but this isn’t the case.

While it may seem natural to consider heat when thinking of IR, it isn’t fully accurate since infrared rays only account for slightly over half of the total solar energy.

Ultraviolet light (UV) makes up around three percent of total solar energy and visible light accounts for around forty four percent. Together, all three of these energies make up the complete solar spectrum.

When comparing how much heat can be rejected by window film, TSER must be considered as well (UV + visible + IR). This is why Total Solar Energy Rejected is such a large factor and must be used to determine the total amount of solar energy that is unable to pass through the glass.

It’s important to know that when a number is used to describe TSER, the higher the number, the greater the amount of total solar energy (heat) is rejected. Many window films will reject anywhere from 30% – 80% TSER. A general rule of thumb is that window films with a high TSER percentage are typically darker and allow less visible light to enter the room. If visible light is important then you must also determine how much you are willing to sacrifice to reach your desired TSER. On the other hand, IR rejection measures the majority amount of heat that can be rejected from infrared.

Choosing the Right Window Film Specifications

While choosing the right window film specifications for your business or home there are a variety of factors to take into consideration. The first is the specific issues you are facing and attempting to resolve. Some of these issues can be furniture and floor fading, privacy concerns, excessive glare, and overwhelming heat. Other factors to consider are levels of visible light you would like to allow into your home or office, along with the level of heat-blocking technology you prefer to reach the optimal comfort level you’d like to achieve.
