Processed Products

Coated glass: A popular glass solution, created by applying one or more coatings of inorganic materials which ultimately alter the physical properties of the glass, including its solar heat gain coefficient (SHGC), emissivity, color, light transmission, and reflection. Coated glass products can be produced through two processes:

  • Sputter or “soft” glass coatings: Applied by bombarding cooled float glass with metal atoms. The specific metal atoms deposited on the glass surface will ultimately determine its performance properties. This process, which takes place in a low-pressure chamber, is known as Magnetic Sputter Vapor Deposition (MSVD). Because it takes place after float manufacturing is complete, sputter coating is often referred to as an “offline” coating method.
