The importance of Safety/Security glass
Demanding safety legislation has highlighted the critical areas where modern safety glazing must comply with the required safe practice allowing people to be protected from personal injury or in the most extreme cases protecting buildings from various forms of attack.
With this in mind, we Stock a wide range of sophisticated products, in order to meet these ever increasing demands, without compromising on the design criteria of natural light and visibility.
Although Safety and Security are closely linked topics, it is important to understand the distinction between the two terms, to ensure the right glass is specified.
The term “Safety” is applied to glazing used to reduce the risk of accident by impact, fracture, shattering.
The term “Security” is applied to glazing, which in addition to “Safety”, is able to withstand a variety of deliberate attacks such as manual, ballistic or blast resistant.
What is toughened glass?
Toughened glass is manufactured by subjecting the final glass size to a heating and cooling treatment which set up high compressive stresses at the surface, and balancing tensile stresses in the centre of the glass, which increases its strength. The result is a glass that is 5 times stronger than ordinary glass of the same thickness.
How it works
The high compressive surface stresses give the glass its increased resistance to mechanical and thermal stresses. It can, however, break under extreme loads or by severe impact. When broken, toughened glass shatters into small, blunt-edged fragments, reducing the risk of personal injury.
What Is Laminated Glass?
Laminated glass is produced by combining two or more sheets of float glass with one or more interlayers. The most popular interlayer used is a polyvinylbutyral (PVB) interlayer, which is processed with heat and pressure under factory conditions.
CGC Laminated safety glass product features:
- EN 12600 achieved through ™ 6.8mm Laminated is the most widely used thickness for protecting people against risk of accidental injury, and is needed for document Q legislation.
- 6.8mm Sound reduction Laminated when applied in IGU format will give an increase level of sound reduction.
- Laminated glass can be used in many applications to enhance security and DB reduction.
- available in a wide range of thicknesses
- Laminated glass contains a PVB interlayer which works as a UV filtration of upto 95%
How it works
The interlayers ensure the integrity of the glass, by holding the broken pieces in place should any damage occur. In fact, glass fragments adhere strongly to the interlayer, while the resistant cushioning effect dissipates the energy. Our laminated glass is called CGC Laminated Its performance can be influenced simply by changing the number and thickness of each layer of glass and PVB interlayer. By doing this, we can offer a wide range of products suitable for many applications.
For additional noise control performance, the product is further enhanced by using specially developed acoustic interlayers.
