Process:

The production process involves perfect cleaning of the glass panes in multi chamber glass washing and drying machine using filtered and de-ionized water and treatment chemicals. These panes are then mechanically transported to a clean and controlled atmosphere chamber, where the temperature and humidity are strictly maintained to exacting standards since unprocessed PVB is extremely sensitive to moisture and temperature. PVB is then applied in this lay-up room and the sandwich of glass and PVB is passed through preheating chamber, pre nip rolls, secondary heating and final nip rolls to squeeze out air bubbles and provide primary bonding.

The sandwiches are then stacked in a high pressure autoclave where PVB is cured under high pressure and temperature as per heat pressure cycle chart. The entire processing is done with computerized state of the art machines and technical assistance of M/s. Scholz of Germany and DuPont of USA. All basic products, heat strengthened glass and toughened glass can be laminated.

Characteristics:

Safety : Laminated glass doesn't shatter like ordinary glass. It absorbs impact, resists penetration and remains in glazing even if broken.

Security : Trutuf laminated glass resists intrusion because the interlayer continues to safeguard the building even after the glass itself is broken. In multiple configurations, it can even resist bullets, heavy objects or small explosions. In most cases, it takes many blows, all in the same spot, to penetrate the glass.

Sound Reduction : Glass is an excellent barrier to noise. The sheer damping performance of the plastic interlayer make the laminated glass an effective sound control product.

UV Control : Glass screens out 99% of the sun's damaging rays, protecting interior furnishing, displays or merchandise from fading effects of UV radiation.

Earthquake & Natural Disaster Protection : Laminated glass remains in the frame, maintaining a protective envelope around the home or building to keep weather out and deter glass shards from flying.

Durability : Laminated glass retains its color and strength for the life of the building, yet is as easily cleaned as any conventional glass.

Fire Retardant : While standard laminated glass doesn’t meet code requirements for fire-resistant glass, it will not disintegrate readily when exposed to heat, so it confines the fire longer, giving more time for evacuation and control of the fire.

Precautions:

In sloped glazing, the added weight of laminated glass must be taken into consideration when determining load limits and installation techniques.

The edges of a laminated lite must not be exposed to any prolonged contact with moisture.

Consideration must be given to the use of weep holes or other alternate glazing procedures to assure a dry framing cavity.

Edge delamination is possible in silicone structural glazing applications if precautions are not taken. U-values may vary by a small amount.

Laminated glass is made by joining two or more sheets of glass with a plastic medium, mostly PVB, between the sheets. PVB itself adheres well to glass. Laminating can also be done with certain resins. Some suppliers use PVC instead of PVB or use cheap resins, which are difficult to make out at the time of supply but these materials will most certainly discolor and delaminate in a short period and such glasses will have to be changed.

Availability:

Safety : Curtain wall and structural glazing, overhead glazing, sloped glazing and skylights, glass floors, aquariums and animal observatory windows, offices, hotels and restaurants, hospital, libraries and museums, airport terminals, residences and apartment buildings.

Wherever noise is a problem, we recommend Acoustic Control Glass.

High security places, for example - banks, teller and drive-through windows, ticket windows, gas stations, currency exchanges, armored vehicles, jewelry shops & burglar resistant showcases, embassies, sensitive research centers, computer centers etc.
