Total infrared rejection properties are calculated over the spectral range of 780 2500nm.
Total solar energy rejection.
Total solar energy rejected tser on angle is not recognized by them as a measure of performance.
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.
Although it may be natural to.
The higher the number the less ultra violet rays are behind transmitted.
The total amount of solar energy heat rejected by the window film glass.
The total solar energy tser specification along with another specification that is commonly used in the glass.
Irr measures only the amount of ir infrared component that is rejected by the window film.
Reported values are taken from representative product samples and are.
So if a film has a 65 ir it means the film rejects 65 but lets in 35 ir.
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.
All film products indeed all glazing systems have improved total solar energy rejection as the sun climbs higher in the sky and sunlight strikes a vertical glass window less directly.
Let us help you understand some of these common terms better.
What is total solar energy rejected.
Separating the ir rejection for purposes of reporting heat gain is misleading.
The higher the.
Data captured using nfrc guidelines and calculated for single pane clear glass.
However irr does not measure the total amount of heat that is.
The total amount of visible light that is transmitted through the window film glass.
The lower the number the less visible light is being transmitted darker.
Total solar energy rejected.
The total amount of ultra violet that is rejected by the window film glass.
Almost all window film block 99 100 of uv rays.
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.
A lot of people think that infrared ir rejection and total solar energy rejection are the same thing but this is not the case.
