VSG laminated glass
What is VSG laminated glass?
VSG laminated glass, or bonded or layered glass, is a special type of glass that consists of two or more panes of glass bonded together by one or more flexible EVA (ethylene-vinyl-acetate) or PVB (polyvinyl butyral) films. The lamination process involves combining those components under temperature and pressure in specialised ovens, ensuring that the film bonds inseparably to the glass.
Laminated glass has a number of advantages:
- minimises the risk of injury in case of breakage
- protects against attempted burglary
- increases the insulation performance of the partition compared to monolithic glass of the same thickness
- reduces the penetration of UV radiation, preventing the colours of walls or furniture from fading.
Basic types of laminated glass and their applications
We distinguish between safety and security laminated glazing:
- laminated safety glass is that which meets the requirements of one of the classes specified in European standard EN 12600. It is used wherever possible damage to or breakage of the glass could cause injury to those in the vicinity. It is most commonly used in the manufacture of balustrades, glass stairs, glass roofs, façades, high-rise façades, glass floors or internal partitions. By using it, life- or health-threatening situations can be avoided.
- safety laminated glass is a construction which meets the requirements of European standard EN 356. It provides temporary protection against burglary. Security glazing will work wherever there is a need to protect property or people, and where bars, shutters or blinds cannot be used for aesthetic reasons.
Types of laminated glass
We can divide laminated glass by the type of glass used during lamination:
- annealed plain glass (VSG), for example, for balustrades or insulating glass units,
- tempered glass (VSG ESG) or semi-hardened (VSG TVG) used mainly for self-supporting balustrades or rotary glass canopies, glass doors, glass stairs and spot-mounted façades.
In addition, there are two types of laminated glass in terms of the film used:
- PVB – most commonly used in insulating glass units, interior glass balustrades, partitions and other interior spaces.
- EVA – non-hygroscopic, moisture-resistant. Mostly used in rooms with moisture (bathrooms) and outdoors (exterior glass balustrades, glass canopies, etc.).
Depending on the customer's needs, we can use different types of film and glass when laminating:
- Film types: transparent, matt, acoustic, coloured
- Glass types: transparent, body-tinted, coated, reflective, mirrors, ornaments.
In addition to its safety qualities, laminated glass is increasingly being used as a decorative element. We can apply an unlimited number of designs to the laminates, in the form of graphics printed on glass or screen printing.
Tempered laminated VSG ESG glass in the Stan-Szkło offering
The VSG/ESG glass is particularly noteworthy.
Due to its properties, this glass is increasingly used in today's architecture. VSG ESG has a higher resistance to the stresses associated with temperature fluctuations and is much more resistant to point compression and breakage than laminated glass made of non-tempered glass. In addition, like all tempered glass, this glass can be subjected to the HST test. Control over every stage of production with such a multi-stage process (cutting, grinding, hardening, laminating) allows us to maintain the highest quality and short lead times.
