Low-E Glass

Description

Low-emission glass (Low-E) is a clear glass, it has a microscopically-thin coating of metal oxide. This allows the sun&#**9;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. Production On-line coated (pyrolitic process): this is a clear glass which has been coated with a metal oxide through pyrolysis when the glass leaves the tin bath (at **0°C). 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): is a clear glass which has received, on one of its faces, a silver coating applied by magnetically-enhanced cathodic sputtering. This type of Low-E must be used exclusively in insulating glass, with the coating on an internal face. It can be tempered and laminated.
