Armoursales anti-attack resistant glass laminates are designed to achieve the optimum delay factor as the first line of defense against intrusion over a considerable period of time by offering resistance to sustained manual attacks from hammers, pick-axes, crowbars, bricks and other heavy implements likely to be employed by criminals.

Laminated glass is produced by bonding two or more sheets of glass under heat and pressure. The inter-layers ensure that the integrity of the glass is maintained during an attack. The length of time a panel can sustain an attack is dependent on the thickness of the glass.

The use of poly carbonate and additional advanced polymers gives these products their extraordinary lightweight feature.

The combination of glass and poly carbonate enables the glass to maintain a high level of visible light transmission.

In general, the greater the total thickness of the laminate, the greater the protection achieved, although care must be taken in the selection of the thickness of the respective components in the lamination.

A major problem with security glazing whether manufactured as anti-attack or anti-ballistic glazing is that while it is possible to design a screen which withstands the force of repeated impact with heavy implements, all determined attacks produce spall off the rear face of the screen glazing.

The spall which consists of glass slivers and fragments can travel at high velocity through the air for some considerable distance during an attack. Hence spall is very dangerous and can seriously lacerate the face of a counter clerk or bank teller standing about 1 meter behind the glass.
