This is made-up of two or more layers of glasses and one or
more inter layers of Plasticized Poly Vinyl Butyral (PVB)
permanently bonded together under heat and pressure. The
constituent glass layers of a laminated glass may be
annealed; heat strengthened or fully toughened and may
have holes and cutouts. Though interlayer of other materials
e.g. EVA, Polyurethane and PET are also used in glass
lamination to meet specific requirements, PVB is the
predominant and most widely used inert layer material for
over six decades. The thickness of the inter layer varies
from 0.38 mm to 1.52 mm for safety applications depending
on the size and the thickness of glass layer and may go up to
3 mm for security applications.
The ability of the laminated glass to retain the glass together in position even after glass
breakage makes it a safety glass. The glass continues to act as a barrier even after breakage
and hence is an ideal glazing solution for overhead, sloped, glazing’s or floorings.
In order to enhance the quality and quantity of production, our company decided to shift from
manual lamination by installing imported pre-processing machines and a lamination line from
Bystronic, Germany.
Features
� High safety performance: PVB film is firm, rich of adhesion and cannot be penetrated
when impacted. Therefore, even when the laminated glass is broken, the sheet glasses are
still able to adhere to PVB films and thus the persons and things around won't be hurt.
� Good sound insulation performance: PVB has good dampening action on sound waves;
therefore, the laminated glasses are able to minimise the transmission of sound effectively
and reduce the noise;
� Ultraviolet radiation prevention: Besides ensuring the visible lights are able to enter
indoors, PVB films are able to block 99% ultraviolet radiation and prevent the furniture and
other items indoors from discoloring due to exposure to ultraviolet radiation.
� Bullet-proof, anti-riot: Due to the toughness of PVB, laminated glass will absorb a large
amount of impact by any foreign object, such as bullets, stones etc.
� Sun control characteristics: Laminated glass with special interlayers reduce the
transmission of sunlight, thereby lowering the energy consumption of refrigeration, while
weakening sun glare without causing color distortion and maintaining the visibility factor.
Following are our brands of laminated glass:
(a) Armor Glass (Laminated glass for safety glazing applications)
A perfect blend of style and strength, laminated glass is the preferred choice amongst
renowned international architects and designers. The unique property of Armor Glass, to
remain integral even after breakage of the glass layer, makes it a perfect solution for
installations, where the barrier property of the glass is the primary architectural design
concern. Armor Glass can be configured with special inter-layers to offer solar performance
with special colors and designs to suit specific application requirements. Armor Glass made
with solid glass fully toughened or heat strengthened greatly enhances strength of the glass.
