Safety glass (extra-strength and safe breaking)

Safety glass (extra-strength and safe breaking)
Choose a suitable safety glass to protect yourself from the risk of serious injury caused by accidental breakage or impact.

Safety glass can be either toughened or laminated depending on where and how it is being used. When it breaks, it breaks safely thus protecting against the risk of serious injury.

How does it work?
There are two glass types available to protect against the risk of injury. The choice is made depending on where and how the glazing is being used.
Toughened safety glass has undergone a heat treatment to increase its overall strength. Generally it is 5 times stronger than normal glass. To give an example a piece of 8mm toughened glass can withstand the impact of a 0.5kg steel ball dropped from 2 metres. If the glass does break, it breaks safely into thousands of tiny pieces with dull, safe edges.
Laminated safety glass comprises two pieces of glass held together by one or several plastic films like a glass sandwich! In the effect of breakage or impact, these films hold the glass in place. The glass still breaks into pieces, but they remain adhered to the film(s).

Benefits
Safety glass has many benefits:

Toughened glass
Avoids potential cuts and injuries as a result of broken glass (for example used in doors, table tops, shower screens etc).
Laminated glass
Laminated glass: assembled using a single plastic film.
basic protection
provides protection against the risk of injuries due to accidental breakage (for example windows or patio doors)
Laminated glass: assembled using two or more plastic films. enhanced protection
provides protection against a change in level (e.g. balconies or guarding) and objects falling on to or penetrating the glass (e.g. glass roofs and canopies).
The pieces of glass stay in place, stuck to the plastic interlayers, until a replacement arrives.
Safety glass for safe breakage or overhead glazing can be combined with other glass functions for additional comfort: security, thermal insulation, acoustic insulation, low-maintenance and decorative glass.

Laminated Glass--Protection against burglary or vandalism

Laminated Glass--Protection against burglary or vandalism

What is it ?
Laminated safety glass are made up of two or more sheets of glass bonded together with a plastic interlayer. After the plastic has been placed between the glass sheets, the whole assembly is subjected to heat and pressure. This results in the complete adhesion of the vinyl and the glass.

In the event of breakage, the glass fragments remain bonded to the plastic interlayer. In a fully framed conventional installation the glass fragments are held together and the glass retains a residual strength while awaiting replacement.

Advantages
This laminated safety glass provides many solutions for the protection of people. If broken, the glass remains bonded to a plastic sheet and is less likely to cause injury to people or property. The plastic sheet also makes penetration more difficult
These glass products are designed for differing levels of protection, from vandalism to burglary

Application
Sloped/Overhead Glazing
Museums, Prisons, Government Buildings
Jewelry Stores, Banks, Airports
Safety Glazing Applications
Schools, Hospitals, Hotels

Ideal for use in interiors, acid etched glass can be sited in a wide variety of applications:
All doors (sliding-glass, French, and patio). 
Side windows within 24 in. of an opening or door. 
Stair landing windows within 4 ft. of the floor. 
Bathroom windows, within 5 ft. of the floor. 
All windows within 18 in. of the floor. 
All tub and shower enclosures.

Installation Guidelines
Toughened glass cannot be drilled or any other processed and edgeworked in any manner. Toughened glass ordered to templates must be accompanied with a full scale template made to the correct dimensions.
Minimum edgework finish on toughened glass up to 12mm is a standard arrissed edge. Minimum edgework on greater thicknesses should be a flat ground edge; 
Slight distortion or bowing may occur after toughening but is largely controllable. It will vary with substance, tint, surface treatment, size and shape of the glass. Ceramic painted, sandblasted or reflective coated glass has a greater tendency to bow and special tolerances would be advised. Flatness will be measured when the glass is standing on edge with a straight edge placed along the full length of the panel and a wedge measurement taken at the centre position. Refer to our technical department for more information.

Glass Stairs

Glass stairs or glass staircases are becoming more and more in vogue. AJJ Glass produce glass components for glass staircase systems; i.e. glass stair treads and glass balustrade infill panels.

Glass stairtreads are generally manufactured using a combination of 10mm float and 25mm float, laminated together. A non slip surface can be achieved in several ways, the most popular being an all over sandblast and ritec coat finish. Another popular anti-slip preference is for grooves to be cut into the front edge of the tread.

Approximately 1m² is usually considered to be a practical maximum area for each panel - due to handling considerations. The glasses should be installed with the thicker glass ply uppermost, and consideration must be given to the surface finish of the glass.

Glass Floor panels

Glass floor panels are increasingly popular in contemporary interior and exterior applications. Glass floor panels allow light to pass from underneath to show illumination or to allow light to brighten the space below the floor.

AJJ Glass Products supplies thick laminated glass floor panels to meet your most demanding requirements and you can have patterns, decorative interlayers, colors, textures and more.

Glass floor panels are usually constructed of 2 or more glass panels, laminated together.

Approximately 1m² is usually considered to be a practical maximum area for each panel - due to handling considerations. The glasses should be installed with the thicker glass ply uppermost, and consideration must be given to the surface finish of the glass.

Glass dance floors for instance are usually specified in 15mm float laminated to 25mm float. Corridors are 25mm laminated to 25mm, and for domestic dwellings, 10mm laminated to 19mm is more usual.

Main steps:
1、Material arrangement
2、Laminating
3、Vacuum & heat
4、Joint wire5、Making protector

Mirrored Glass

To produce mirrored glass, a metal coating is applied to one side of the glass. The coating is generally made of silver, aluminium, gold or chrome. For simple mirrored glass, a fully reflective metal coating is applied and then sealed with a protective layer. To produce "one-way" mirrors, a much thinner metal coating is used, with no additional sealing or otherwise opaque layer.

Mirrored glass is gaining a more prominent place in architecture, for important functional reasons as well as for the aesthetic effect.

Coated

Surface coatings can be applied to glass to modify its appearance and give it many of the advanced characteristics and functions available in today's flat glass products, such as low maintenance, special reflection/transmission/absorption properties, scratch resistance, corrosion resistance, etc.

Coatings are usually applied by controlled exposure of the glass surface to vapours, which bind to the glass forming a permanent coating. The coating process can be applied while the glass is still in the float line with the glass still warm, producing what is known as "hard-coated" glass.

Alternatively, in the "off-line" or "vacuum" coating process, the vapour is applied to the cold glass surface in a vacuum vessel.

Annealed Glass

Annealed glass is the basic flat glass product that is the first result of the float process. It is the common glass that tends to break into large, jagged shards. It is used in some end products -- often in double-glazed windows, for example. It is also the starting material that is turned into more advanced products through further processing such as laminating, toughening, coating, etc.

Laminated Glass

Laminated glass is made of two or more layers of glass with one or more "interlayers" of polymeric material bonded between the glass layers.

Laminated glass is produced using one of two methods:

Poly Vinyl Butyral (PVB) laminated glass is produced using heat and pressure to sandwich a thin layer of PVB between layers of glass. On occasion, other polymers such as Ethyl Vinyl Acetate (EVA) or Polyurethane (PU) are used. This is the most common method.

For special applications, Cast in Place (CIP) laminated glass is made by pouring a resin into the space between two sheets of glass that are held parallel and very close to each other.

Laminated glass offers many advantages. Safety and security are the best-known of these -- rather than shattering on impact, laminated glass is held together by the interlayer, reducing the safety hazard associated with shattered glass fragments, as well as, to some degree, the security risks associated with easy penetration. But the interlayer also provides a way to apply several other technologies and benefits, such as colouring, sound dampening, resistance to fire, ultraviolet filtering, and other technologies that can be embedded in or with the interlayer.

Laminated glass is used extensively in building and housing products and in the automotive and transport industries. Most building façades and most car windscreens, for example, are made with laminated glass, usually with other technologies also incorporated.

Toughened glass

Toughened glass is treated to be far more resistant to breakage than simple annealed glass, and to break in a more predictable way when it does break, thus providing a major safety advantage in almost all of its applications.

Toughened glass is made from annealed glass treated with a thermal tempering process. A sheet of annealed glass is heated to above its "annealing point" of 600 °C; its surfaces are then rapidly cooled while the inner portion of the glass remains hotter. The different cooling rates between the surface and the inside of the glass produces different physical properties, resulting in compressive stresses in the surface balanced by tensile stresses in the body of the glass.

These counteracting stresses give toughened glass its increased mechanical resistance to breakage, and are also, when it does break, what cause it to produce regular, small, typically square fragments rather than long, dangerous shards that are far more likely to lead to injuries. Toughened glass also has an increased resistance to breakage as a result of stresses caused by different temperatures within a pane.

Toughened glass has extremely broad application in products both for buildings and for automobiles and transport, as well as other areas. Car windshields and windows, glass portions of building façades, glass sliding doors and partitions in houses and offices, glass furniture such as table tops, and many other products typically use toughened glass. Products made from toughened glass often also incorporate other technologies, especially in the building and automotive & transport sectors.
