Total Solar Energy Rejection Window Film

The industry accepted and most accurate performance values used to report heat gain or rejection due to the application of window film are solar heat gain coefficient shgc and its counterpart total solar energy rejected tser.

Total solar energy rejection window film.

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. Lets go through these few specifications that are most common in all window film one by one so that consumers can understand better. The sum of the tser total solar energy rejection in decimal form of a glazing system and its shgc value is 1. 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.

Total solar energy rejected. Total solar energy rejected tser on angle is not an industry accepted measure of a films performance and therefore cannot be used to assert the superiority of one film product over another. Comparing window tinting film. Therefore 1 tser shgc thus if the tser of a specified film glass combination is 58 then 1 58 42 which is the shgc of the window.

Window films alone cannot lower the temperature of a room but they can reduce the rate that energy enters a room which helps reduce the load placed air conditioning systems. The nfrc is the only independent agency to rate window performance and. 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 tser is a factor that describes the total amount of solar energy uv visible ir that is rejected from passing through glass.

The total amount of visible light that is transmitted through the window film glass. Total solar energy rejected tser on angle is not recognized by them as a measure of performance. Total solar energy rejected is the amount of heat that is cut out by the film. Clearly then when we read the specification called total solar energy rejection we can now see that it is not referring to temperature reduction percentage but rather it is the percentage of incident solar energy rejected.
