Toughened glass is actually made from annealed or float glass. Float glass is heated to more than 600 °C and then quickly cooled. If broken, it shatters into many small blunt pieces. Due to the increased heat treatment and rapid cooling of the glass especially between the surface and the inside of the glass, the treatment produces different physical properties which result in compressive stresses on the surface and balanced stresses in the body of the glass which makes the toughened glass stronger than float glass. A very high grade tempered glass that is several orders of magnitude stronger than ordinary glass. Tempered glass makes glass safer and durable by lowering the risk of impact-related breakage.
The tempered glass retains the light transmission and energy properties of the base product. Once toughened, they can no longer be cut or shaped.
When float glass breaks, it shatters into dagger-like pieces and can be harmful, it is therefore unsuitable for some applications, whereas toughened glass shatters into small chunks which are less likely to harm than the usually jagged shards(Big Sharp Pieces) produced when annealed glass breaks which can easily cause injury.
Toughened glass is treated in such a way as to enable it to be more resistant to breakage. This is a major safety advantage of this glass in almost all of its applications.
Laminated glass, regarded as “Safety glass”, consists of two or more panes of glass with one or more layers of Poly-Vinyl Butyral (PVB) or Ethylene-Vinyl Acetate (EVA), sandwiched between them and treated. The glass panes can be basic float glass or tempered or heat strengthened panel. If the glass is broken fragments tend to adhere to the PVB interlayer thereby reducing the risk of injury from falling glass and helping to resist further impact or weather damage. PVB membrane has good tenacity performance and when the laminated glass breaks due to violent force, the PVB will absorb a large amount of impact energy and disperse it rapidly. Therefore, it hard to break the laminated glass and the shape of the glass may be maintained even if being broken. Furthermore, personnel inside and outside the buildings will not be hurt by the glass fragment.
Features of Laminated Glass
SAFETY
An important feature of laminated glass is its performance under impact. That is, the interlayers in laminated glass have the capacity to absorb the energy of impact and resist penetration. Safety hazards caused due to breakages are minimized with the use of laminated glass. Although the glass may break, the glass fragments will adhere to the plastic interlayer, minimizing the risk of injury and property damage.
SECURITY
Burglars often break windows to get to the door and window handles, but laminated glass can resist the intrusion because it is virtually impossible to cut through the thick PVB layers even if the glass gets broken.
SOUND CONTROL
Laminated glass has proven to be an excellent noise barrier. The shear damping performance of the PVB makes laminated glass an effective sound control product. UV CONTROL While natural light plays an important role in architectural design, Ultra Violet (UV) rays in the sunlight can cause itching and fading of curtains/furniture. Laminated glass can block over 99% of the UV rays while allowing most of the visible light through.
WEATHER AND DISASTER CONTROL
Laminated glass helps protect from injury and property damage caused by glass breaking because of natural disasters such as hurricanes and earthquakes.
DURABILITY
Laminated glass is exceptionally durable, maintaining its color and strength. It can be used for a variety of architectural and interior design applications such as floor glazing, stairs, balconies, balustrades, internal paneling, and exterior cladding as well as for the more traditional doors and windows.
DESIGN VERSATILITY AND INSTALLATION EASE
Laminated glasses can be manufactured flat or curved. They can include annealed, toughened, heat-strengthened, wired, patterned, tinted, or reflective glasses. Interlayers can be used to add color tints and for further aesthetic and privacy needs. Laminated glass is simple to install. If the glass is not heat-treated, it can also be cut, drilled, or notched.
Insulated Glass, often called double glazing, is a combination of two or more panes of glass spaced apart with a spacer bar and hermetically sealed with a primary and secondary sealant to form a single unit with one or more air spaces in between. IG units improve thermal performance, thus significantly reducing heating and air-conditioning costs. IG units also reduce interior condensation in cold climates, and increase comfort near windows, thus maximizing the usable interior space.
By combining Low-E coatings, tinted glasses, reflective coatings, silk-screened patterns, laminated glass products, and more, a wide variety of insulating glass configurations are available to satisfy a wide range of performance and aesthetic requirements. IG units can be fabricated to meet state energy codes, sound control requirements, seismic requirements, impact resistance, bullet resistance, and hurricane and blast resistance requirements. IG units can be designed to reduce heat loss and solar heat gain entering the building, with a minimal reduction of visible light transmittance.
IGU (Insulated Glass Unit) FEATURES
OPTICAL PROPERTIES
The visible light transmittance of insulating glazing systems is normally in the range of 7-80% and the visible light reflectance is in the range of 13-48%
THERMAL PROPERTIES
The U value is effectively lowered by insulating glazing and can be further reduced by filling inert gases
ACOUSTICAL INSULATION
Insulating glazing can reduce noise by about 30dB and further reduction is obtainable by filling inert gases and using laminated glazing.
CONDENSATION
The dew point of CSG insulating glazing systems is below-65C which guarantees no condensation formation under normal applications.
SEALING
The aluminum spacer frame is automatically curved and formed with only one joint and two seals are applied in insulating glass production, which ensures excellent sealing characteristics and a long application life-time.
Bent Glass is made via heating flat glass until soft, carefully formed to the desired shape, and then annealed by controlled cooling to minimize trapped energy within the glass. The resulting bent annealed product offers un-enhanced strength and the stability of minimized internal stresses.
BENT CAN BE TRANSFORMED INTO THE FOLLOWING TYPES:
• Tempered Bent Glass
• Laminated Bent Glass
• Insulated Bent Glass
APPLICATIONS
• Architectural bent glass applications
• Curved Railings
• Refrigerating Counters
• Display counters
• Curved windshields
• Glass Furniture
