glass coating, coating, Low-E, hard coat, soft coat

Coating

Glass coatings come in different varieties and serve different purposes, from strictly aesthetics (how the glass looks) to practical (how it performs), such as Low-E glass. Coatings can be applied during the float process, while the glass is warm, and those are referred to as hard coats; or a coating can be applied in post-production, via a vacuum process, which creates a soft coat.
