Bullet proof glass

Bullet proof glass (also known as ballistic glass, transparent armor or bullet-resistant glass) is a type of strong but optically transparent material that is particularly resistant to being penetrated when struck by bullets, but like all other known materials, is not completely impenetrable. It is usually made from a combination of two or more types of glass, one hard and one soft. The softer layer makes the glass more elastic, so it can flex instead of shatter. The index of refraction for both of the glasses used in the bulletproof layers must be almost the same to keep the glass transparent and allow a clear, non-distorted view through the glass. Bulletproof glass varies in thickness from three-quarter inch to three inches (19mm to 76mm).

Another construction method, which is becoming popular rapidly, is the use of security laminates as a film on the inner surface of ordinary glass. This, when bonded with the application of a pressure sensitive adhesive and cured fully, also provides a protection similar to the multi-layered bullet-resistant glass. The optical clarity is much better and tint-free, thickness and weight are reduced as much as 50–70%, and the process can be done as a retrofit on existing windows.

Advantages

1. Safety. Laminated glass is hard to be penetrated and can remian integrally in the frame even when it is broken.

2. Sound insulation. PVB can effectively prevent sound wave. Sound wave can be obviously weakened when it goes through laminated glass so that noise disturbance in offcie or living environment is reduced.

3. Ultra-violet resistance. Laminated glass can effectively prevent UV (as high as more than 99% of UV) whcih can protect the valuable furnature, exibit and artwork etc. from discoloring from UV.

4. Public security. Laminated glass's high persistent and strong cohesion enable the fragments remain in place, thus it is suitable for hurricance and earthquake zone.

5. Multi-layer laminated glass can be made into various products of anti-bullet, anti-bombing and anti-explosion.
