Other window films won t change heat rejection at any angle.
Total solar energy rejection tint.
This is a comparison for the 3m window films heat rejection.
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.
The higher the percentage the higher the percentage of solar energy deflected.
The total amount of solar energy heat rejected by the window film glass.
The higher the number the less ultra violet rays are behind transmitted.
Therefore when looking for tint that blocks the most heat it would not make sense to only look at individual ratings such as ir rejection.
This is because all formulaone films block 99 of the uv spectrum and if we are comparing the same vlts 50 vlt vs 50 vlt the solar energy contribution from the visible light spectrum is the same.
Total solar energy rejected.
Tser includes visible light infrared radiation and ultraviolet energy.
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.
When developing and comparing films with like technologies and the same vlts only the ir spectrum can be impacted to improve the performance specs.
Sunlight solar radiation is made up of 2 ultraviolet 49 visible light and 49 infrared energy and all of this energy generates heat if it enters a room through a window.
Separating the ir rejection for purposes of reporting heat gain is misleading.
Keep in mind that the sun will come in at an angle of 60 degrees or more for most of the day.
Total solar energy rejected tser is the percentage of the total solar energy that is rejected.
The higher the.
Almost all window film block 99 100 of uv rays.
When the sun is directly overhead all vertical windows with or without film have 100 total solar energy rejection.
Llumar atc series window film offers 99 uv rejection up to 44 total solar energy rejection tser suntek carbon series window film offers 99 uv rejection up to 46 total solar energy rejection tser ceramic window tint best for maximum heat rejection glare rejection and scratch resistance.
My understanding is the total solar energy rejection tser is the best indicator of performance since it includes all three sources of heat.
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.
