WHAT IS LOW
Low-Emissivity (Low-E) coatings are microscopically thin metal layers that are deposited on the glass surface to help keep heat on the same side of the glass from which it originated. These coatings have been developed to minimize the amount of ultraviolet and infrared light that can pass through glass without compromising the amount of visible light that is transmitted.
Low-E coated glass delivers year-round comfort in all types of weather. In summer, it rejects the sun’s heat and damaging UV rays. In winter, it reflects heat back into the room. When the interior heat energy tries to escape to the colder outside during the winter, the Low-E coating reflects the heat back to the inside, reducing heat loss through the glass. The reverse happens during the summer.
It may be surprising to learn that up to 25% of the heat in a home can be lost through the windows. Without energy-efficient glazing, you are effectively throwing your money out of the window. By installing Low-E windows, you can significantly improve your energy ratings and reduce the amount of energy lost through your windows by up to 75%!
SILVER LAYERS OF LOWE GLASS
Within the coating structure of single silver Low-E glass, there is one silver layer. Single Silver Low-E glass is not very common.
While maintaining the same visible light transmittance, it has lower shading coefficient, SC, than single silver Low-E glass. In other words, it filters the sunshine as a cool lighting source to a larger extent and provides a solution to energy efficiency.
Performs better against solar heat than double silver Low-E glass and is currently the best silver based Low-E glass in terms of high visible light transmission and energy efficiency.
