Low-E glass (low emissivity glass), is an advanced technological form of glazing which has quickly gained prominence within the construction and architectural industries. Specifically designed to reduce heat transfer while increasing energy efficiency in buildings. Low-E glass is coated with an invisible metallic layer to serve as a thermal barrier and allow visible light through while reflecting significant infrared energy back out into space. This special treatment also prevents intruding infrared energy from coming through to reach our eyes directly, further decreasing energy loss through infrared radiation. Low-E glass helps ensure a more consistent indoor climate by limiting heat loss during colder months and blocking solar gain during warmer ones. Low-E glass has become an effective solution for improving insulation, decreasing energy use and creating more environmentally sustainable living and working spaces. Due to its exceptional thermal properties, low-E glass has quickly become one of the go-to choices in energy-efficient buildings - contributing significantly towards green architecture advancement.
