|Laminated Tempered Safety Glass Curtain Walls|
A layer of PVB film is sandwiched between two or more pieces of tempered glass of any other colors in tempered laminated glass which is processed under high temperature and pressure. Laminated glass is durable and provides long service life. The tough PVB film absorbs a great number of energy impacts when the glass is broken by violent external force. Therefore, laminated glass maintains perfect integrity and is not likely to be broken down. Even being broken, laminated glass is fully maintained inside door and window frames, which protects the inside room from being damaged by foreign objects and avoid the injury to personnel inside and outside the building resulting from splashing substances or broken glass pieces. Such characteristics make laminated glass be widely recognized as the truly safe glass.

In geographical areas requiring hurricane-resistant construction, laminated glass is often used in exterior storefronts, curtain walls and windows. The PVB interlayer also gives the glass a much higher sound insulation rating, due to the damping effect, and also blocks 99% of incoming UV light.

1) 5 times harder than ordinary float glass.
2) Once breakage occurs, the glass disintegrates into small cubical fragments, which are relatively harmless to human body.
3) It withstands abrupt temperature change of 220 Centigrade.
4) Sizes are produced as per customer request. Once tempered, can not be cut down.
