Low-Emittance (Low-E) is a term used for a surface that radiates, or emits, low levels of radiant energy. Low E Glass is most commonly used in architectural windows to reflect radiant energy. This coated material helps to reduce heat loss but allows the room to be warmed by any sunshine. Low E glass also helps to eliminate the transmission of degrading UV rays. Most of the Low-E glass supplied by JNS Glass & Coatings is used in the foodservice industry for applications such as ovens.
