1, Laminated glass is a kind of construction safety glass; it is made of 2 or more layers glass, heated and pressed with PVB. Its appearance and installment is basically same as ordinary glass. The laminated glass keeps as same pure and transparent as ordinary ***** (1) Anti-impact: Effectively resist external impact, even gets broken, the pellets will stick middle membrane and will not hurt people. (2) Anti-penetration: Even if destroyed and appears aperture; its gap is tiny. (3) Anti-irradiation: Effectively weakens the ultraviolet rayincident intensity, meanwhile, will not lessen visible light and cause the chromatic distortion. (4) Soundproof: Eliminate resonance and assimilate both low and high frequency sound wave. (5) Bulletproof: Prevent people from glass fragment injury when it receives attack. (6) Decorative：To carry on handling curving, the color axis, the coloration, the frosting, the mirror surface, printing and the melt ties of the laminated glass processing according to artistic and safe needs 2, Insulating glass is made of two pieces of glass, sealed up with strong pressurization viscose and aluminum alloy frame with desiccating agent in the middle, the space between two pieces of glass always keeps dry. 3, The process of tempered glass is to heat the original glass to a very high temperature and cool it down rapidly to make the surfaceof the glass compressive. According to the shape, it can be divided into the fully tempered glass and the semi-tempered glass (also called heat strengthened glass).
