Visible light transmittance: Visible light (380-780) through the percentage of the glass/window film composite layer.
Visible light reflectivity: Visible light (380-780) percent reflected by the composite layer of glass/glazing membranes.
Solar penetration Rate: The percentage of solar energy through the glass/glazing membrane composite layer.
UV-Barrier Rate: ultraviolet (280-400) The percentage of the composite layer reflecting the glass/window film.
Solar reflectance: The percentage of the solar energy being reflected by the glass/foil composite layer.
Solar Absorption Rate: The percentage of solar energy absorbed by the glass/foil composite layer.
Total solar penetration Rate: solar energy through the glass/glazing membrane composite layer and absorbed into the internal radiation of the total solar energy.
Total Solar reflectance: That is, the heat insulation rate, it is the solar energy by the glass/window film composite layer reflecting part and absorbed into the external radiation of the total solar energy.
Masking coefficient: The total solar penetration rate of glass/window film composite layer relative to glass.
U value: hourly, internal and external temperature difference each degree, through the amount of thermal radiation per square foot.
