Glass Performance

INFRARED
Transmission percentage represents the amount of heat from the sun that your window allows to pass into your home.  You can save money on their energy bills by blocking the sun's heat.  Different coatings and films on glass will function differently regarding infrared energy. For Far Infrared (FIR), both soft coat and hard coat Low E coatings reflect thin long-wave infrared energy (heat) back inside a home, thus reducing heat loss through the windows. For Near Infrared (NIR), spectrally selective coat Low E coatings prevent significant portion of the NIR energy transmitting through a window. The NIR energy is reflected away from a window, thus reducing the amount of NIR energy that is permitted into a building to be converted to long-wave (FIR) heat.
