Laminated Glass

Laminated glass, regard as “Safety glass”, consist 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 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 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 barrier to noise. 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 provide protection from injury and property damage caused by glass breaking because of natural disasters such as hurricane and earthquake.

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.
