Total Solar Energy Rejection Tint

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.

Total solar energy rejection tint.

Separating the ir rejection for purposes of reporting heat gain is misleading. 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. When developing and comparing films with like technologies and the same vlts only the ir spectrum can be impacted to improve the performance specs. Total solar energy rejected tser is the percentage of the total solar energy that is rejected.

My understanding is the total solar energy rejection tser is the best indicator of performance since it includes all three sources of heat. The total amount of ultra violet that is rejected by the window film glass. Other window films won t change heat rejection at any angle. 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.

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. 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. Tser includes visible light infrared radiation and ultraviolet energy. The crystalline films heat rejection gets higher the greater the angle.

Most tinting shops use infra red rejection irr as a guide to the level of heat rejection. The higher the. Total solar energy rejected. Almost all window film block 99 100 of uv rays.

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. The higher the percentage the higher the percentage of solar energy deflected. 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. The higher the number the less ultra violet rays are behind transmitted.

When the sun is directly overhead all vertical windows with or without film have 100 total solar energy rejection.
