Window Tinting Technical Terms
HELLO ALL.
Some new tinters asked me about definitions of some terms provided in the tint technical specifications. I am writing about most of the technical terms of window tinting.
SOLAR ENERGY TRANSMITTED is the radio of the total solar energy passing through the glazing system to the amount of total solar energy falling on that glazing system.
SOLAR ENERGY ABSORBED is the ratio of the amount of the total solar energy directly reflected by the glazing system to the amount of the total solar energy falling on that glazing system.
SOLAR ENERGY REFLECTED is the ratio of the amount of the total solar energy directed by the glazing system to the amount of total solar energy falling on that glazing system.
PLY is used to display the number of separate layers of polyester film that are used in the manufacturing process to make a particular window film product. Example: A 1-ply product would consist of one single layer of polyester film where a 3-ply product would be made with three separate layers of various types of polyester film.
MIL THICKNESS is the metric system unit of measurement equal to one thousandth of a meter. Mil thickness is used in the GWF nomenclature to display the overall thickness of the window film product in terms of millimeters (MIL)
VISIBLE LIGHT TRANSMITTED (VLT) is the ratio of visible solar energy (380-750nm) that passes through the glazing system to the total visible solar energy falling on the glazing system.
VISIBLE LIGHT REFLECTED (VLR) is the total percentage of visible light reflected by a glazing system that can be seen visually. GWF performance results includes interior and exterior VLR specifications on all films.
ULTRAVIOLET REJECTED (UVR) is the ratio of ultraviolet solar energy (wavelength of 300 -380nm) that is transmitted by glazing system to the total solar ultraviolet energy falling on the glazing system.
SHADING COEFFICIENT (SC) is the ratio of the solar heat gain through a given glazing system to the solar heat gain under the same conditions for clear plain glass. The lower the shading co-efficient number, the better the sun control capability of the glazing system.
SOLAR HEAT REDUCTION (SHR) is the reduction in solar energy gained by a building from the sun, often by the addition of solar control window film.
TOTAL SOLAR ENERGY REJECTED (TSER) is the percentage of incident solar energy rejected by glazing system which is equal to solar reflectance plus the part of solar absorption which is re-radiated outward.
GLARE REDUCTION (GR) is the percentage of reduction in visible light transmission through a glazing system without film to that with film.
EMMISIVITY (E) is a measure of surface's ability to absorb or reflect far-infrared radiation. The lower the emissivity the higher the infrared reflection. Infrared radiation is that which is sensed by the body as heat. the lower the emissivity, the better the insulating qualities of the glazing system.
U-VALUE is a measure of the rate of heat conductivity of a glazing system and it is independent of solar radiation. The lower the U-value the better the insulation qualities of the glazing system.
All right. You can now study technical specifications of all window films and then you can choose your favorite window film. Solar Control Films has 90 different types of window films with different colors. Visit Solarcontrolfilmsinc.com and get more information about your window films. SCF has free energy audit for you.
