Products - Laminated Curved Glass
There are 2 types of safety glass, one being toughened and the other laminated.
Laminated glass is made by bonding 2 or more panels of glass together. The principle is that even if one of the panels forming the laminate is damaged or cracked the integrity of the entire panel is still maintained from a safety point of view.
Toughened glass on the other hand when broken ‘explodes’ into many small harmless fragments. This means that where the glass panel forms a barrier as in a toughened glass balustrade, on exploding there is no barrier remaining. This is normally overcome by laminating 2 toughened panels together.
Applications: Laminated glass is best used where safety, security or sound reduction considerations are paramount. Its ability to stop sunlight from fading colours in internal furnishings is also an important factor in many applications.
Versatility of laminated glass: The basic process of laminating glass together affords a wide choice of composites, which in turn means it is suitable for a wide range of applications.
For example you can have 3 or 4 layers in the laminate to achieve different security levels even to the point of stopping rifle bullets. In these instances the framework that ‘houses’ the glass, usually in steel, forms an integral part of the protective screen. Safety considerations, to stop someone being injured from an accident, would include areas such as glass in doors, glass overhead in a roof or canopy, or large shop windows.(These are normally a double ply of a suitable thickness). You could even bond 2 panels of tinted glass together to match an existing heavier tinted glass.
So, whether there is a need for a glass screen to provide security up to bullet proof level or to a lesser degree withstand the blast of a shotgun or the attempts of a burglar to gain entry to a premises, laminated glass can provide the solution. Laminated glass is also very good for sound reduction because the interlayer by its very composition helps to deaden the noise level by 35 – 40 dB. Not to be overlooked is its ability to minimise the colour fading effects of sunlight on internal furnishings by cutting out most of the harmful U.V rays.
Areas for application: include shop windows, office partitions, overhead glazing in canopies or domes, security screens, balustrade panels, stair treads and floor panels.
Note: Where laminated glass is made from two or more panes of annealed glass, it does not have the same structural properties as toughened glass. It should not therefore be considered for use where the glass forms part of the structural element of a building.
