Low-emissivity. Emissivity is the relative power of a surface to emit heat by radiation. A "low-e" metallic coating on window's glass pane slows the rate at which the glass will absorb heat, thus providing better insulation.
A "SHORT HAND" TERM FOR LOW EMISSIVITY COATED GLASS. IT IS A METALLIC OXIDE COATING APPLIED DIRECTLY TO THE GLASS IN EITHER A SOFT-COAT OR HARD COAT VERSION. THE COATING IS NEARLY INVISIBLE AND EASY TO SEE THROUGH. IT REFLECTS AWAY THE LONG-WAVELENGTH INFRARED RADIATION WHICH CUTS DOWN THE HEAT TRANSFER BETWEEN THE SHEETS OF GLASS.
(Low-Emissivity) insulating glass Low-E insulating glass provides the best year-round performance and lowers energy costs by at least 15 percent (based on savings over clear glass). Low-E glass features transparent microscopic layers of silver placed between layers of anti-reflective metal oxide coatings. These coatings block 83 percent of harmful UV rays and 96 percent of the sunâ€(tm)s infrared heat, so homes stay cooler in the summer and interior furnishings fade less. In the winter, Low-E helps keep homes warmer for improved comfort and reduces condensation. It also delivers greater visible light transmittance than tinted glass.
refers to a material designed to reduce the amount of radiant heat that can be transferred through glass or other translucent window coverings. Low-e (which stands for low-emissivity) coatings or films have the ability to re-radiate a high percentage of heat back toward its source. In summer low-e windows can be effective in reducing the amount of solar heat that can enter a house, and in winter they can reduce the amount of furnace-generated heat that can be lost to the outdoors.
Low emissivity, Low-E glass products are coated with microscopically-thin, optically transparent layers of silver sandwiched between layers of anti-reflective metal oxide coatings. In the summer Low-E glass products let in visible sunlight while blocking infrared and ultraviolet solar energy that drives up cooling costs and damages curtains, window treatments, carpeting and furnishings. In the winter, Low-E glass products offer greater comfort and reduced heating costs by reflecting room-side heat back into the room.
Most often used in reference to a coating for high-performance windows, the "e" stands for emissivity or re-radiated heat flow. The thin metallic oxide coating increases the U-value of the window by reducing heat flow from a warm(er) air space to a cold(er) glazing surface. The best location for the coating is based on whether the primary heat flow you want to control is from the inside out (heating climates) or the outside in (cooling climates).
stands for "low emissivity". Low-E coating on a window pane lets light in, yet reflects heat and keeps harmful UV rays out in the summer and keeps heat inside during the winter.
Low emissivity glazing has a thin metallic coating applied to glass or plastic. It reduces heat loss and solar heat gain through glazing.
A low emissivity coating applied to glass to reflect radiation and increase window efficiency.
An abbreviation for Low Emissivity coatings. They are applied to glass to reflect invisible long-wave infrared or heat. They reduce heat gain or loss in a building by redirecting the heat. In addition, they typically provide greater light transmission, low reflection and reduce heat transfer.
