Laminated Glasses

 

Laminated glass is a combination of two or more glass sheets with one or more plastic inter layers

(EVA /PVB /SGP)sandwiched by the glass sheets. In case of breakage the interlayer will hold the glass fragments together. It is manufactured through a process of heat and vacuuming.

 

Laminated glass is used when there is a possibility of human impact or where the glass could fall if shattered. It can be found in windshields, skylights, balconies, bank teller windows, and jewelry counters to name a few applications.

 

Interlayer Film : SGP / PVB / EVA

Cost: SGP > PVB > EVA

Safety:SGP > PVB > SGP

Color:EVA > PVB > SGP

(also EVA does well connected with many different materials,so it’s a very nice interlayer for decoration glass)

Bulletproof glass is als laminated glass, it is several film and glass laminated.

Normally,it comes with PVB,dear client,if you have enough budget,then think about SGP  : )

 

We are known in the industry for offering a complete range of Laminated Glasses comprising PVB Laminated Glass and EVA Laminated Glass in various dimensions, as per the specifications of our clients. These glasses are widely applicable in homes and offices owing to their distinguishing features of high strength, soundproof, anti-shock and fade resistance. Our range of precisely designed Laminated Glasses is explained below:

 

PVB Laminated Glass

Laminated glass, commonly used in the automotive and architectural fields, comprises a protective inter layer, usually polyvinyl butyral, bonded between two panels of glass. The bonding process takes place under heat and pressure. When laminated under these conditions, the PVB inter layer becomes optically clear and binds the two panes of glass together. Once sealed together, the glass “sandwich” (i.e., laminate) behaves as a single unit and looks like normal glass. The polymer inter layer of PVB is tough and ductile, so brittle cracks will not pass from one side of the laminate to the other.

 

We source a wide range of Laminated Glasses from trusted vendors of the industry. PVB Laminated Glass is formed from a combination of two or more glass sheets with one or more inter layers of plastic (PVB) or resin. The inner plastic offers strength to the glass, especially in case of a breakage. In such as case, the interlayer holds the fragments together and continues to provide resistance. These glasses are best suited for shop-fronts, balconies, stair-railings and roof glazing, where it is important to ensure the resistance of the whole sheet after breakage.

We offer two types of laminated glasses, PVB and resin laminated glass. PVB laminated glass is formed by the combination of two or more sheets of glass which are bonded together with one or more layers of PVB under heat and pressure. The resultant is a single piece of glass. On the other hand, resins laminated glass is manufactured by pouring liquid resin into the cavity between two sheets of glasses that are held together till the time resin gets cured. Our range of PVB Laminated Glasses is characterized by the following features:

 

Good safety performance

Anti-bumping and anti-shock

Pierce resistance

Soundproof and heat isolated

Strong UV resistance

Available in diversified colors

Durable and fadeless

 

The range is offered in the following technical specifications, to suit the diverse requirements of our clients.

 

Maximum size: 2000 mm × 3000 mm

Minimum size: 300 mm × 300 mm

Thickness: 4 -80 mm

Number of layers: 1- 4

PVB color: Clear, milky, gray, blue, green, pink and bronze

PVB thickness: 0.38 mm, 0.76 mm and 1.52 mm or above

 

EVA Laminated Glass

We are engaged in supplying Resins Laminated Glass that is manufactured by pouring liquid resin into the cavity between two sheets of glasses. These sheets are held together until the resin cures. The material of construction used in laminated glasses is a high adhesive film made of polymer resins of ethylene vinyl acetate. Further, the range is appreciated by the clients for the following features:

 

Excellent safety performance

Wide range of processing temperature

High anti-aging and optics performance

Suitable for small oven producing

Simple curing process

Storage at normal temperature

Good adhesive to other material

 

We offer laminated glasses in different dimensions of thickness, width and length to meet the diverse requirements of the clients:

 

Thickness: 0.15 mm, 0.20 mm, 0.25 mm, 0.38 mm, 0.76 mm, 1.14 mm

Width: 1800 mm x 2200 mm

Length: 150 m, 100 m per roll

 

Fabric EVA Lamination is the combination of plain, tinted, reflective, figured, mirror in various thickness from 2 mm to 12 mm with clear, colored films and clothes. it is frequently used by architects and interior decorators for various application such as exterior, interior and decorative purpose.

It has following advantages:

  • Anti UV clear
  • Transparent colors
  • White Opaque
  • Transparent clear
  • Opaque colored
  • Frosted effect.

Tempered Heat Socked Glass

Overview of Heat Soaked Glass:

Tempering process increases the strength of glass many folds, offering a greater resistance to breakage. However, the raw-materials used in the manufacturing of tempered glass are not free from certain defects like nickel-rich contaminants such as stainless steel might be present, and then combine with sulphur to form nickel sulphide inclusions, which put tempered glass at potential risk of spontaneous breakage.

 

Spontaneous breakage due to NiS inclusions:

When glass is heat-treated, the nickel sulfide inclusions are modified into a form that grows or transforms with time and temperature. Once glass is installed and the nickel sulfide inclusions are solar heated, small cracks may develop from the inclusion. If these cracks penetrate the tension layer of fully tempered glass, the resulting release of energy will cause the glass to spontaneously break.

 

NiS inclusions change their structure and volume during the heating process of tempering. This changed state is ^trapped^ during the quenching process. So at room temperature, the NiS inclusions tend to change back to their original state, which having bigger volume, cause spontaneous breakage. This changing back of state could happen in a few minutes to a few years, making it unpredictable when the tempered glass may break. To minimize the risk of NiS breakages, a heat soak test is performed.

 

Heat Soak Process:

Effective Heat soaked test has been proposed and applied for tempered glass to avoid spontaneous failure in buildings, and the probability of spontaneous breakage was decreased. However, it was considered that a sufficiently low breakage risk was remained because of small NiS inclusion and small residual stress.

 

Heat soaking of tempering glass has carried out in respect to the draft of European Standard EN 14179. Following the tempering process, glass is heated to a temperature of about 290C for a minimum of 2 hours of the heat soak period, and then cooled slowly. This process allows the inclusions to revert to their original form and thus regain their stability. The advantage in using this process is that the heat-soak test removes over 95% of the problem without affecting the properties of the glass. The idea behind heat soaking is to allow the glass to break in the factory before installation to minimize the risks of accidents and injury. The amount and size of these inclusions vary from glass to glass. In all probability, the glasses that have NiS inclusions will break during this heat soaking process.

 

Applications of Heat Soaked Glass:

The use of heat soaked tempered glass is recommended where the risk of spontaneous breakage would cause difficulty, either from a replacement point of view, or where falling glass fragments may be unsuitable, such as roof or high level glazing, balustrades, screens and high level curtain walling.

Heat soak glass is appropriate where there is a risk of human impact. If breakage does occur, the breakage pattern is such that the resultant pieces of glass are relatively harmless and are unlikely to cause severe injury.
