Total Solar Energy Rejection Tint

Other window films won t change heat rejection at any angle.

Total solar energy rejection tint.

The total amount of solar energy heat rejected by the window film glass. The higher the. Most tinting shops use infra red rejection irr as a guide to the level of heat rejection. 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.

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. 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. Keep in mind that the sun will come in at an angle of 60 degrees or more for most of the day.

The higher the percentage the higher the percentage of solar energy deflected. 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 crystalline films heat rejection gets higher the greater the angle.

The higher the number the less ultra violet rays are behind transmitted. Separating the ir rejection for purposes of reporting heat gain is misleading. Tser includes visible light infrared radiation and ultraviolet energy. 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. 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. This is a comparison for the 3m window films heat rejection. The total amount of ultra violet that is rejected by the window film glass.
