Laminated Glass - A type of safety glass that has a layer of plastic bonded between layers of glass. The film gives the glass an added degree of resistance to breakage.
Safety Glass - A general term used for either laminated or tempered glass. Only glass which has been laminated, can specifically be called laminated safety glass.
Tempered Glass - A strong, break-resistant type of safety glass that, if broken, shatters into small granular pieces.
Sandblasting - Sand blown by compressed air for etching or decorating glass.
Heat Strengthened Glass - Similar to tempered glass, it is made by heating annealed glass uniformly and then cooling it more slowly than tempered glass.
IG Units - Common name for insulating glass units. Two lites of glass, separated by an air space, hermetically sealed to form a single-glazed unit, to improve insulation against heat transfer and/or sound transmission (also known as an insulated glass unit).
Wired Glass - Made by feeding a welded wire net of a particular design into the molten glass just before it enters the roller. The wire holds the lite in the sash in the event of breakage.
Coated Glass - Glass with a chemical film applied to one surface. The film can provide such enhanced performance characteristics as privacy, solar or mirror effects.
