Laminate glass consists of two layers of flat glass with middle varnish or Poly Vinyl Butriral or PVB for short. In this method, glass and talc are glued together to form a laminate unit.
mostly used to increase safety, because if the glass is broken due to the presence of the middle of the glass, it does not lose its overall geometric shape and remains in its frame. Laminated glass is also a good insulator to control sound and UV rays.
Ordinary glass is broken in impact and turns into small pieces that will carry many dangers. If the laminated glass, due to having PVB talc, absorbs the force of the impact and as a result shows more resistance to the impact.
If the laminated glass is broken, the middle layer of PVB prevents the broken pieces from scattering around, in other words, the said layer adheres to the broken glass pieces, holding them together, thus the risk of damage and Injury is greatly reduced.
Sound insulation The sound resistance of laminated glass is significant, so that it prevents the entry of sounds from outside and is considered as sound insulation compared to ordinary glass.
UV control The main causes of erosion and discoloration of furniture and carpets are the interaction of chemical interactions created by the sun's UV radiation. UV absorbent additives used between the PVB layer in laminated glass can partially prevent these harmful rays and reduce the damage.
This type of glass can be used in commercial and residential buildings, offices, airports, banks, hospitals, factories, elevator cabins and floors, roof coverings, swimming pools and skylights, shop windows, greenhouses, partitions and In general, he used places where safety and security, as well as reducing noise pollution and harmful solar rays, are of great importance.
Also, laminated glass is a suitable option for use in buildings in areas where there is a strong wind and there is a risk of storms and dust. In the event of an earthquake, the laminated glass used in the building shows a much higher safety.
Bulletproof glass is similar in appearance to ordinary glass and in practice, due to their much higher resistance than ordinary glass, they prevent it from passing after being hit by a bullet. Bulletproof glass is made by laminating several layers of glass on top of each other.
In some cases, in order to increase the strength of the bulletproof glass produced, the middle glass is selected from the type of Securite glass. The middle polymer layer used to glue the glass together (laminating) itself significantly increases the tensile strength of the glass.
When a bullet hits this type of glass, it passes through the initial layers of glass and the kinetic energy of the bullet is taken by these layers and the bullet is no longer able to pass through the final layer and gets stuck inside the glass. Of course, there is a breakdown threshold for bulletproof glass, which depends on the type of bullet and the number of shots fired.
