Total Solar Energy Rejection Tint
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 rejection tint. The higher the number the less ultra violet rays are behind transmitted. The higher the percentage the higher the percentage of solar energy deflected. 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.
Separating the ir rejection for purposes of reporting heat gain is misleading. The total amount of ultra violet that is rejected by the window film glass. 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.
Total solar energy rejected tser is the percentage of the total solar energy that is rejected. 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. Tser includes visible light infrared radiation and ultraviolet energy. 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.
This is a comparison for the 3m window films heat rejection. Total solar energy rejected. 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. The crystalline films heat rejection gets higher the greater the angle.
The higher the. The total amount of solar energy heat rejected by the window film glass. Most tinting shops use infra red rejection irr as a guide to the level of heat rejection. My understanding is the total solar energy rejection tser is the best indicator of performance since it includes all three sources of heat.
Other window films won t change heat rejection at any angle.
