Below is a list of Coated Glass manufacturers from Ontario. Coated glass is standard glass which has been covered with a substance to protect or alter its appearance or performance. Glass is used in a number of applications which undergo certain levels of stress and therefore standard glass needs reinforcing in many of those applications. Examples would be heat resistant glass and sight glass. Coatings may be applied to any glass material or product, including car window shields, window panes, mirrors, bottles, interior architectural components and parts of DVD and CD players.
