    Security Glass is produced worldwide for a range of applications using many different manufacturing methods, as a result there is often some confusion as to which construction is most suited to which application.

    To help explain it’s probably best to give a brief guide of the most commonly used types of glass, and how some are used in the manufacture of security glazing systems.

    Float Glass

    Float glass is a single monolithic piece of flat glass; it’s made by floating molten glass on a bed of molten metal to give the sheet a uniform thickness and very flat surface. When used on its own, float glass has almost no security value as it’s easily broken and breaks into large, jagged shards.

    Toughened Glass

    Toughened glass is manufactured by subjecting the float glass to a heating and cooling treatment. A balance of high compressive stresses at the surface and tensile stresses in the centre of the glass increases its strength. The result is a glass that is approx. 5 times stronger than ordinary glass of the same thickness, but it can be easily broken by an impact such as a ball hammer, where upon it breaks into small, blunt-edged fragments instead of splintering into jagged shards. When used alone it could be considered safety glass but has little security value as it leaves nothing in place to protect your assets.

    Laminated Glass

    Laminated glass is manufactured by bonding together two or more layers of high quality float glass under heat and pressure using an interlayer such as polyvinyl butyral (PVB). In this instance the PVB serves to maintain the integrity of the glass following deliberate or accidental damage. Dependent on the make up of the laminated glass, it could be considered a safety, attack or bullet resistant glass:

    Laminated Safety Glass is intended for use in architectural applications where in the instance of accidental damage the use of monolithic glass would present a hazard. Laminated safety glass may crack locally following impact, but will retain its' integrity. Typically, Laminated Safety Glass is a 3 ply construction, consisting of two layers of glass sandwiching an interlayer, the thickness of both the glass and PVB can be varied to give a number of different options dependent on application, but even when laminating toughened or heat strengthened glass they do not always provide the level of integrity of multiple layered constructions you can find in bullet resistant glazing.

    Laminated Security Glass

    Security Glass is a broad term used to describe multiple products that ultimately offer people or possessions protection against a threat.  The term can cover Bullet Resistant, Blast and Manual Attack glass to name but a few.  Standard laminated glass can even offer a degree of security compared to a single toughened or float panel.
