Composite glass is the collective term for a laminate having at least two glass panes which are in each case connected by means of an adhesive intermediate layer composed of plastic, e.g. by means of a casting resin or a thermoplastic composite film, which is highly tear-resistant and is viscoelastic. Composite glass should not be confused with ...
Laminated glass is a type of safety glass consisting of two or more layers of glass with one or more thin polymer interlayers between them which prevent the glass from breaking into large sharp pieces. [1]
Glare grades 1, 2, 3, and 6 have just two plies of glass fibers, so the thickness of an individual glass fiber layer is 0.25 mm (0.0098 in; 9.8 mils). Glare4 has three plies, so its glass fiber layers are each 0.375 mm (0.0148 in; 14.8 mils) thick.
For this reason, it is not considered a safety glass and must be laminated if a safety glass is required. Chemically strengthened glass is typically six to eight times the strength of annealed glass. The glass is chemically strengthened by submerging the glass in a bath containing a potassium salt (typically potassium nitrate) at 450 °C (842 °F).

Plastic screen protectors cost less than glass and are thinner (around 0.1 mm (0.004 in) thick, compared to 0.3 to 0.5 mm (0.012 to 0.020 in) for glass) [2] and more flexible. At the same price, glass will resist scratches better than plastic, and feel more like the device's screen, though higher priced plastic protectors may be better than the ...
