Glazing on building is particularly vulnerable if an explosion occurs nearby. The resulting high energy forces can cause the glass to break into pieces and become dangerous flying missiles capable of inflicting injury to people and causing extensive damage to property and equipment.
As a precaution, an organisation representing the interests of the British insurance industry has had Clear Safety film installed on the glazing of its Gresham Street Head Office in the City of London. The film forms a strong transparent shield that strengthens the glass to BS6206: 1981 Class A.
In the event of an explosion it absorbs energy from the blast and reduces the level of shattering and flying shards, thus reducing the risk to personnel and property.
The Opalux 200-micron optically clear safety film is specially structured, strengthened and coated with a formulated adhesive which bonds it to the glass. It is made up of multiple layers of polyester film laminated together to give superior break and tear resistance.
