In most of the cases it is seen that majority of the window panes come with some sort of glass coatings. However, the thickness of these coats may differ depending on the requirement and the purpose of the pane. Most often than not, a number of fine layers of film are gelled together, with one side coated with adhesive whereas, on the other you would notice a scratch resistant and hard coating.
There are numerous types of coats that are applied on window panes. Some of the basic ones are:
* Deposited film: In such coats the film is, first of all, drawn through a big container which contains metal ingots. This metal ingot is mainly of nickel-chrome or aluminum and at times copper. It is important to remember that in order for deposited film to work effectively it is necessary for the coat to be quite thick, mainly because the particles are fairly large.
* Dyed film: These types of glass coatings largely help to absorb heat. Since in most cases these types of window coats are applied on the inner surface of the pane, it is easy to understand that the heat, which gets absorbed, would be dispersed indoors. The heat which gets rejected by these types of window panes are mainly stored in the glass which ultimately gets carried away with the breeze outside. It is good to know that since double-glazed windows prevent air movement, especially in between the panes; internal dyed films should not be used on thermal glass. In most of the houses in some of the major cities in the US, like Tacoma and Bonney Lake, you would notice people using this type of glass coatings.
