The total amount of ultra violet that is rejected by the window film glass.
Total solar energy rejection window film.
Two common heat rejection indexes used are irr infrared rejection and tser total solar energy rejection.
The total solar energy tser specification along with another specification that is commonly used in the glass industry called the solar heat gain coefficient shgc are two excellent ways for a consumer to compare the performance of one window film to another.
There are some key terms you should understand when shopping for and comparing window film.
The higher the number the less ultra violet rays are behind transmitted.
The ir rejection rate is a number that lets customer understand that the film can reject majority of the heat from infrared it does not mean that if a large portion of the ir is blocked.
The shgc or its counterpart the total solar energy rejected tser reflects the true performance of solar heat gain or rejection through a window int o a building and its calculation includes ir rejection.
It comes with different specifications that cater to various needs from controlling visible light transmission to the ir rejection uv rejection and finally adjusting the total solar energy rejected tser.
Free window coating for entire car.
A deeper look at the specifications of a window film.
Window films alone cannot lower the temperature of a room but they can reduce.
Almost all window film block 99 100 of uv rays.
Film model black rainbow 97.
All film products indeed all glazing systems have improved total solar energy rejection as the sun climbs higher in the sky and sunlight strikes a vertical glass window less directly.
Films with higher numbers create more comfortable living spaces.
Total solar energy rejected tser is a factor that describes the total amount of solar energy uv visible ir that is rejected from passing through glass.
Speaking of which not all window films are made the same.
World class insulation film 97 heat insulation photochromic technology solar film best heat rejection top tser rejection.
Choose the window film with the highest heat rejection rate.
Total solar energy rejection 65 multilayer security film.
The total amount of solar energy heat rejected by the window film glass.
Separating the ir rejection for purposes of reporting heat gain is misleading.
Once the window film company and the film dealer or installer have been selected the next is to choose the film with the highest heat rejection rate.
If you want a film that cuts out the most light and heat choose one with a very low vlt around 5 15 and a very high total solar energy rejected around 80 85.
Total solar energy rejected.
Front back screen window film.
When the sun is directly overhead all vertical windows with or without film have 100 total solar energy rejection.
Light transmission a measurement that indicates how dark.
The higher this number is the more heat the film will stop from entering the room.
