Total Solar Energy Rejected, Explained

Why You Should Know About Total Solar Energy Rejected

There is no denying that it can be difficult to understand the different window film specifications that are available. However, it is important to know how much sunlight and heat can pass through a window. This is not only imperative in terms of creating the right environment but it is important for health purposes too, such as reducing the risk of skin cancer. With that being said, below, we will explain what total solar energy rejected means, to help you get a better understanding. 

What Is Total Solar Energy Rejected?

In order to determine how much heat a window and window film can block, you need to check the specifications for Total Solar Energy Rejected. A lot of people think that infrared (IR) rejection and total solar energy rejection are the same thing, but this is not the case. Although it may be natural to consider heat when you think of IR, this is not accurate because infrared rays only account for just over half of the total solar energy. Around three percent is made from ultraviolet (UV) light and then visible light accounts for around 44 percent. All three of these energies make up the solar spectrum. When we refer to total solar energy, this is what we are referring too. Because of this, when we are comparing how much heat can be rejected by window film, TSER must be contemplated, i.e. UV + visible + IR. Therefore, Total Solar Energy Rejected is a factor that is used to determine the total amount of solar energy that is not able to pass through the glass. 

When a number is presented to describe TSER, the higher the number is, the greater the amount of total solar energy, i.e. heat, that is rejected. Most window films on the market today will reject anywhere from 30% - 80% TSER. As a general rule of thumb, window films with a high TSER percentage are darker and allow less visible light to enter the room. If visible light is important to you, then you must determine how much visible light you are willing to sacrifice coming in to the room to reach the TSER percentage you desire.

IR rejection, on the other hand, is a number that enables the consumer to understand that the majority of heat can be rejected from infrared. However, this does not indicate that almost no heat is going to be transmitted through the window film. There are other types of window films as well, for example, that only handle visible light transmission. 

Choosing the Right Window Film Specifications

When choosing the right window film specification for your business environment or home, there are a number of different factors to take into account. The first factor is the issues that are facing your office or house, for example, furniture/privacy or fading/glare/heat. Other elements you need to consider are the level of visible light you would like into your office or house, as well as what sort of heat blocking technology you would prefer. Asking for a sample in order to do a demo test comes advised too. 

So there you have it: everything you need to know about Total Solar Energy Rejected. Hopefully, this has helped you to get a better understanding regarding the different window film specifications that are available. This is important when looking for the right product for your business or home.
