One of the main concerns of architecture in recent times is to protect the buildings from terrorist activities. Even the glass manufacturers are working very hard to manufacture glasses that will resist the heat and the impact blast-resistant building of bullets and bomb blasts.
These are commonly known as blast resistant glass. When a blast occurs, one of the chief things that harm people around is shards of broken glass. During a blast, the glasses in close proximity break and fly in the air in the form of sharp tiny pieces. Thousands of tiny shards of glass flying in the air prove to be very dangerous. These shards have the ability of flying to a distance due to the pressure wave in the air created by the explosive device.
resistant glazing has the ability of absorbing a lot of the energy Blast-Resistant Building Rentals created by the blast. The blast resistant glass can also deflect the energy. The manufacturers of glass have studied the effects of a blast in a building and have come up with the concept of resistant glazing.
The blast resistant glass is made in a way that it does not break away from the frame and fly around in the form of glass debris. When a blast is unable to break the glass, the integrity of the building is not lost.
How is blast resistant glass made?
Laminated glasses offer a higher degree of protection as they are thicker than regular glass. Laminated glasses are made by introducing a layer of PVB or Polyvinyl Butyral between two layers of glass. The PVB has a minimum thickness of 1.5 mm while laminated glasses have a minimum thickness of 7.5 mm. resistant glazing does not break; instead they bend under the impact.
However, the blast resistant should not be too rigid. This has an adverse effect during the blast. If the resistant glazing is too rigid it tends to transfer the entire energy of the blast to the frame and the structure of the building. The building gets affected badly as the forces of the blast penetrate the building
