Flat Laminated Tempered Glass, PVB Film Toughened sandwiched Safety
6.38mm thickness light green, bronze laminated tempered safely
glass with 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.
Laminated glass is normally used when there is a possibility of
human impact or where the glass could fall if shattered. Skylight
glazing and typically use laminated 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
