Light Transmission (TL). Total amount of light visible, which goes through a glazing. It's expressed as a percentage between the light transmitted and the light that falls on the glazing.
Light Reflection (RL). Amount of visible light which is refleted by a glazing. It`s expressed by the percentage that result of dividing the reflected light between the light that influence this glazing.
Energy Transmission (TE). Amount of energy, which goes through a glazing. It's expressed as a percentage between the energy reflected and the energy, which falls on the glazing.
Energy Reflection (RE). Amount of energy reflected by a glazing. It`s expressed by the percentage that result of dividing the energy reflected between the energy that influence this glazing.
Solar Factor (FS). Total amount of energy that goes through the glazing.
Coefficient K. Amount of energy, expressed in kilocalories, lost by transmission through a square meter of glazing per hour and per every º C of difference between the interior and the exterior of a glazing (Kcal/m2 h º C). |  |
