For years, window glazing has been a pliable white substance that was sold in a can or sometimes a caulking tube. It was applied to the edge of a glass pane after the piece of glass had been set in place with window points. The material was applied with a special tool called a glazing knife and after the material was installed it was primed with paint and then painted the same color as the wooden window sash.
Glass Coating

As of 2010, window glazing can also refer to a high tech coating applied directly to the surface of the entire glass window. This clear sheen will moderate radiation from the sun, so that on cool days the sun rays are allowed to pass through the glass and heat the house. However, on hotter days the new coatings will block out sun radiation to create a cooling effect.

In the building market of the 21st century, high tech windows are sold with several pieces of glass installed with an air space in between the glass and sealed with a high-tech glazing system. The air space is actually a vacuum, which increases the insulation value, and more often than not the glazing consists of plastic weather stripping that seals and holds the glass in place.
