Low-Emissivity glass (Low-E) is a glass having a microscopically-thin coating of metal oxide. This allows the sun's heat and light to pass through the glass into the building. At the same time it blocks heat from leaving the room, reducing heat loss considerably.

On-line coated (Pyrolitic Process) glass is coated with a metal oxide through pyrolysis when the glass leaves the tin bath. The coating is therefore very resistant to mechanical damage, and this Low-E glass can be cut, tempered or laminated just as normal uncoated glass.

Off-line coated (Magnetron Process) glass received one or several silver coating applied by magnetically-enhanced cathodic sputtering. This type of Low-E must be used exclusively in DGU, with the coating on an internal face. It can be heat treated and laminated.
