What is laminated glass ?
Laminated glass is a multifunctional glazing solution, often used for its exceptional safety properties. Composed of several layers of glass and plastic films, it plays a key role in protecting against glass breakage and the risk of injury. If the glazing breaks, the plastic films (PVB or Evasafe) hold the glass fragments in place, thereby reducing potential hazards.
VIT STOP CHOC custom-made laminated glass consists of layers of glass and PVB or Evasafe films, forming a solid, impact-resistant unit that remains in place even after breakage. This product is particularly suitable for applications requiring enhanced safety, especially in high-risk areas.
The advantages of custom laminated glass
Enhanced Security
In the event of breakage, the plastic films hold the glass in place, preventing injury.
Burglary protection
VIT STOP CHOC laminated glass provides a deterrent against vandalism and break-ins.
Customised aesthetics
Available in a variety of finishes (opal, decorative, burglar-proof), these glazing options can be adapted to suit all architectural styles.
Sustainability
Thanks to the accumulation of layers of glass and film, laminated glass is thicker and stronger than standard float glass.
Technical characteristics of custom laminated glass
VIT STOP CHOC laminated glass consists of several layers of glass (clear float glass, coloured glass, etc.) and plastic films. The standard thickness of PVB films is 0.38 mm, and that of Evasafe films is 0.40 mm. The glass is therefore thicker and more resistant than standard glass, offering enhanced safety performance.
Definition of laminated glass compositions
The designation of laminated glazing follows a simple rule: XXY or XX.Y or XX/Y, where :
XX, where each X corresponds to the thickness of a float glass component (in mm).
Y represents the number of plastic films integrated into the glazing.
Example: A laminated glass composed of a 4 mm glass and a 6 mm glass with two plastic interlayers is designated as 46², 46.2 or 46/2.
Classification of laminated glass
The EN 12600 standard defines the safety levels and the behavior of glazing in case of breakage based on a pendulum test (double tire test simulating the fall of a 50 kg mass on samples measuring 1938 mm x 876 mm).
This classification is expressed according to:
This classification is expressed according to:
The level of impact to which the sample has been subjected :
• 1 for a drop height of 1200 mm
• 2 for 450 mm
• 3 for 190 mm
The type of breakage. It is expressed from A to C (annealed glass A), (laminated glass B), (tempered glass C).
The maximum level of stress that the product has significantly withstood (without allowing a 76 mm sphere to pass through and without significant glass fragments being projected). This level is expressed on a scale of 0 to 3.
1B1 glazing is therefore laminated glass whose sample has been subjected to a drop of
1200 mm and has withstood level 1 stress.
1200 mm and has withstood level 1 stress.
The EN 356 standard classifies glazing according to its resistance to attacks, thrown objects or attempted break-ins.
Vandal-resistant glazing, classes P1A to P5A (4.1 kg ball dropped from a height of 1.50 m to 9 m).
Burglar-resistant glazing, classes P6B to P8B (hammer and axe attacks).
Please feel free to take a look at the STOP CHOC PLUS range, our burglar-resistant glazing.
The EN 356 standard defines the ability of glazing to withstand projectiles.
